     DETAILED DESCRIPTION 
     Network-connected computing devices can provide their users with an unprecedented ability to engage in interpersonal communication. People may engage in messaging interactions with their friends, family, coworkers, and other associates. A user&#39;s message exchanges with their contacts may each be maintained within a distinct message thread. 
     These network-connected computing devices can also provide their users with access to network-accessible services. For instance, transportation services, dining services, entertainment services, and other services may use web sites, web applications, client applications, or other network-accessibility techniques to empower people to use their client devices to engage with their services. In some cases, such as some entertainment or media services, the service can be both arranged and delivered via the client devices. For example, music may be purchased via a client device and delivered to the client device for playback. In other cases, such as with transportation, dining, and in-person entertainment, the service can be arranged via the client devices, but is performed external to the client device. For example, a ride-sharing service may be arranged via a client device but performed through a vehicle and driver providing ride sharing to the user. 
     In some cases, the use of a network-accessible service may relate to more than one person. Particularly where a user&#39;s access to the service is a client device that they also use for messaging, a user may benefit from sharing their engagement with the network-accessible service in the messaging client with the others to whom the service relates. As such, message threads may act as hubs for a user&#39;s online social relationship with their contacts, with the message threads incorporating services requested, monitored, or engaged with via the same client used for messaging. 
     To aid a user in interacting with a service via a messaging context, services may be represented as messaging bots within a messaging system. A messaging bot may be an automated front-end to a network-accessible service that can be represented as a participant within a message thread. In some cases, a messaging bot may be corresponded with in a message thread that explicitly includes the messaging bot, such as a one-on-one message thread between a particular user and the messaging bot. In other cases, a messaging bot may be corresponded with in a message thread in which the messaging bot is not a regular participant, the messaging bot a temporary participant in the message thread for the purposes of interacting with the service. The messaging bot may be included as a temporary participant in any other thread, whether a one-on-one thread between two users or a group thread between multiple users. 
     In some cases, the use of a network-accessible service may relate to more than one person. Particularly where a user&#39;s access to the service is a client device that they also use for messaging, a user may benefit from sharing their engagement with the network-accessible service in the messaging client with the others to whom the service relates. As such, message threads may act as hubs for a user&#39;s online social relationship with their contacts, with the message threads incorporating services requested, monitored, or engaged with via the same client used for messaging. 
     To aid a user in interacting with a service via a messaging context, services may be represented as messaging bots within a messaging system. A messaging bot may be an automated front-end to a network-accessible service that can be represented as a participant within a message thread. In some cases, a messaging bot may be corresponded with in a message thread that explicitly includes the messaging bot, such as a one-on-one message thread between a particular user and the messaging bot. In other cases, a messaging bot may be corresponded with in a message thread in which the messaging bot is not a regular participant, the messaging bot a temporary participant in the message thread for the purposes of interacting with the service. The messaging bot may be included as a temporary participant in any other thread, whether a one-on-one thread between two users or a group thread between multiple users. 
     As such, a user may engage with network services within the familiar experience of a messaging client. Further, by using a messaging client, a user may engage with network services within a messaging context so as to allow the inclusion of other people. In some cases, this may simply inform the other people as to the services, such as letting friends or family know about transportation details. In other cases, this may empower the performance of services for multiple people, such as where dinner, a ride, entertainment, or other service is arranged for the use of multiple people. As a result, the embodiments can improve the experience of using network-accessible services and can extend the reach of network-accessible services to the user of a messaging system. 
     Users may be suggested bots with which to engage with. These suggestions may be made within the context of a message thread between two or more users. As such, these suggestions may be made using techniques that control the amount of screen space used to display the suggestions. These suggestions may be controls that, when selected, instantiate a larger interface for the configuration of a service request with a messaging bot. 
     A developer may be aided by being provided a natural way to specify the capabilities of their messaging bot. The bot platform may provide a bot engine that empower developers to define the capabilities of their bots using a set of developer-defined examples. Examples may be example statements or conversations that the developer believes should cause their messaging bot to be recommended. As a result, the embodiments can reduce the difficult of determining messaging bots for recommendation to a user. 
     Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in block diagram form in order to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives consistent with the claimed subject matter. 
     It is worthy to note that “a” and “b” and “c” and similar designators as used herein are intended to be variables representing any positive integer. Thus, for example, if an implementation sets a value for a=5, then a complete set of components  122  illustrated as components  122 - 1  through  122 - a  may include components  122 - 1 ,  122 - 2 ,  122 - 3 ,  122 - 4  and  122 - 5 . The embodiments are not limited in this context. 
       FIG. 1  illustrates a block diagram for a consumer-to-business communication system  100 . In one embodiment, the consumer-to-business communication system  100  may comprise a computer-implemented system having software applications comprising one or more components. Although the consumer-to-business communication system  100  shown in  FIG. 1  has a limited number of elements in a certain topology, it may be appreciated that the consumer-to-business communication system  100  may include more or less elements in alternate topologies as desired for a given implementation. 
     A consumer-to-business service  110  may serve as an intermediary between consumers and businesses. Consumers and businesses may both be users of the consumer-to-business service  110 , with consumers represented via an individual user account and businesses represented by a commerce account and, possibly, one or more individual user accounts associated with the business, such as individual user accounts associated with representatives and other employees of the business. A consumer user may be represented with a user entity in a social graph. A business or other commercial user may be represented by a business entity in a social graph. The relationship between the consumer user and the commercial user may be represented by one or more edges between the user entity and business entity in the social graph. 
     The consumer-to-business service  110  may comprise a messaging system  140 . The messaging system  140  may be generally arranged to receive, store, and deliver messages between individual entities such as individual users and collective entities such as businesses and other organizations. The messaging system  140  may store messages while messaging endpoints, such as messaging endpoint  125 , are offline and deliver the messages once the messaging endpoints are available. The messaging system  140  may empower a user to use multiple messaging endpoints (e.g., a messaging client on a mobile device, a web browser on a personal computer) for the same user account, with the messaging system  140  keeping all of the messaging endpoints up-to-date as to the messaging state of the user account. 
     The consumer-to-business service  110  may comprise a social networking service  130 . The social networking service  130  may maintain a social graph data structure representing a social graph. The social graph may represent relationships between entities, such as user entities, commerce entities, and any other sort of entity. The social graph may represent the relationships as graph relationships, in which all information is encoded as either being attached to a particular node in the graph or attached to a particular edge between two nodes in the graph. A messaging system  140  may be an element of a social networking service  130 , with the social graph containing, at least in part, social-networking information. The whole of the consumer-to-business service  110  may be an element or composed of elements of a social networking service. 
     The consumer-to-business service  110  may comprise a consumer portal  150 . The consumer portal  150  may be a unified entry point into the consumer-to-business service  110  for client applications being used by consumers. The consumer portal  150  may serve as a general user portal for non-commerce entities, including users that are not or do not engage in commerce using the consumer-to-business service  110 . The consumer portal  150  may provide access to the messaging system  140  and the social networking service  130 . In some embodiments, all access to the social networking service  130  may be mediated by the consumer portal  150  in which the information of the social networking service  130  is used and managed on behalf of the user without the user having direct access to some or all of the social graph information. In some embodiments, the user may have direct access to the messaging system  140  using their user account, with the consumer portal  150  limited to consumer functions of the consumer-to-business service  110  with general messaging functionality (e.g., messaging with friends) provided through direct network communication between the messaging endpoint  125  and the messaging system  140  without the mediation of the consumer portal  150 . 
     The consumer-to-business service  110  may comprise a business portal  160 . The business portal  160  may be a unified entry point into the consumer-to-business service  110  for client application being used by business entities. The business portal  160  may provide access to the messaging system  140  and the social networking service  130 . In some embodiments, all access to the social networking service  130  may be mediated by a business portal  160  in which the information of the social networking service  130  is used and managed on behalf of the business entity without the business entity having direct access to some or all of the social graph information. In some embodiments, the business entity may have direct access to the messaging system  140  using their commerce account, with the business portal  160  limited to business functions of the consumer-to-business service  110  with general messaging functionality (e.g., messaging with customers) provided through direct network communication between one or more bots  190  and the messaging system  140  without the mediation of the business portal  160 . 
     A user may participate in the consumer-to-business communication system  100  and interact with the consumer-to-business service  110  using a messaging endpoint  125  software application executing on a client device  120 . The client device  120  may typically be a smartphone—a mobile phone capable of executing software applications that provide functionality beyond that of a conventional telephone—such as an iPhone®, Android® phone, or other smartphone. The messaging endpoint  125  may be specifically associated with a particular messaging system  140  that forms part of the consumer-to-business service  110  or may be a general-purpose messaging client operative to interact with a plurality of messaging services. The messaging endpoint  125  may interact with one or both of the consumer portal  150  and the messaging system  140  for the performance of messaging tasks and commerce tasks. 
     A business entity may be represented in a messaging system by a commerce representation comprising a collection of information for display to a user. A commerce representation may comprise a business page, the business page being the identity of a business within the consumer-to-business communication system  100 . The business page may display information regarding a business entity. The business page may include information for the business entity, such as one or more of a physical location for the business entity, the operating hours of the physical location, or the hours in which the business entity (e.g., a representative of the business entity) is available for messaging through the consumer-to-business communication system  100 . The business page may include social-networking information for the business entity, such as a list of friends of a viewing user that have “liked” or “followed” the business entity within a social network as may be represented in a social graph. 
     A commerce representation may not correspond precisely to a business entity. A single business entity, such as a business, may have multiple commerce representations and therefore multiple business pages. For example, a single business may have different representations for different brands owned and operated by the same business. A retailer or reseller may sell multiple brands and may have different representations for different brands that they sell. A business may have different representations for different geographic areas in which they operate, such as one business page for the United States, another for Europe, another for Russia, etc. 
     To aid a user in interacting with a service within a messaging context, services may be represented as bots  190 . A bot may be a fully or partially automated front-end to a network-accessible service that can be represented as a participant in an interaction. In some instances, an interaction may comprise a messaging interaction embodied within a message thread, with the bots  190  comprising messaging bots. In some cases, a messaging bot may be corresponded with in a message thread that explicitly includes the messaging bot, such as a one-on-one message thread between a particular user and the messaging bot. In other cases, a messaging bot may be corresponded with in a message thread in which the messaging bot is not a regular participant, the messaging bot a temporary participant in the message thread for the purposes of interacting with the service. The messaging bot may be included as a temporary participant in any other thread, whether a one-on-one thread between two users or a group thread between more than two users. 
     Bots  190  may interact with users using communication channels other than messaging. For example, a bot may comprise a voice bot operating via a voice system, such as a smartphone, personal computer, voice-activated appliance, or other device with which a user may interact via voice. In these embodiments, the voice system may perform voice recognition and voice generation on behalf of the bots  190 . Other types of interactive systems may be used to mediate between bots  190  and users. 
     A messaging bot for a commerce representation may be presented in a messaging conversation in a messaging system  140 . A user of the messaging system  140  may interact with a business by messaging with the messaging bot that comprises a virtual representation of the business. A messaging bot may specifically correspond to a commerce representation presented as a business page, with the messaging bot being the representation of the business page in a messaging context. Messaging with the bot may therefore extend the presence of a commerce representation from a business page, primarily dedicated to providing information from the business to users, to interactive messaging in which users and the business can engage in a conversation. 
     A business may use one or more commerce applications to engage with the messaging system  140 . An application may correspond to a specific registration empowering access to the messaging system  140  and/or social networking service  130  via an application programming interface (API). An application may be registered with the messaging system  140  via various registered hooks for the application specifying how the application can be contacted by the messaging system  140 . These hooks may be used to contact the application in response to events, such as user messaging, within the messaging system  140 . An application may be assigned a secure token that may be used for authentication and the secure (e.g., encrypted) reception and sending of information with the messaging system  140 . An application may correspond to a specific AppID with the messaging system  140  and/or social networking service  130 . Because the business may surface multiple aspects of the services and products it provides via the agent, multiple different applications may be used by a business entity to interact with a user via the messaging system  140 . Each application may be subscribed with the messaging system  140  to the one or more commerce representations, such as business pages, that it powers. 
     The network  180  may comprise any form of computer network operative to carry computer transmissions between computer devices. The network  180  may include one or both of intranets and the Internet. The network  180  may include cellular data and/or Wi-Fi data networks, such as may be used to provide connectivity to a mobile client device  120 . 
     The consumer-to-business communication system  100  may use knowledge generated from interactions between users. The consumer-to-business communication system  100  may comprise a component of a social networking service  130  and may use knowledge generated from the broader interactions of the social networking service  130 . As such, to protect the privacy of the users of the consumer-to-business communication system  100  and the larger social networking service  130 , consumer-to-business communication system  100  may include an authorization server (or other suitable component(s)) that allows users to opt in to or opt out of having their actions logged by the consumer-to-business communication system  100  or shared with other systems (e.g., third-party systems), for example, by setting appropriate privacy settings. A privacy setting of a user may determine what information associated with the user may be logged, how information associated with the user may be logged, when information associated with the user may be logged, who may log information associated with the user, whom information associated with the user may be shared with, and for what purposes information associated with the user may be logged or shared. Authorization servers or other authorization components may be used to enforce one or more privacy settings of the users of the consumer-to-business communication system  100  and other elements of a social networking service  130  through blocking, data hashing, anonymization, or other suitable techniques as appropriate. For example, while interactions between users of a social networking service  130  and the social networking service  130  may be used to learn media content preferences and the relationship between preferences for different pieces of content, these interactions may be anonymized prior to or as part of the learning process. 
       FIG. 2  illustrates an example of a social graph  200 . In particular embodiments, a social-networking system may store one or more social graphs  200  in one or more data stores as a social graph data structure. 
     In particular embodiments, social graph  200  may include multiple nodes, which may include multiple user nodes  202  and multiple concept nodes  204 . Social graph  200  may include multiple edges  206  connecting the nodes. In particular embodiments, a social-networking system, client system, third-party system, or any other system or device may access social graph  200  and related social-graph information for suitable applications. The nodes and edges of social graph  200  may be stored as data objects, for example, in a data store (such as a social-graph database). Such a data store may include one or more searchable or queryable indexes of nodes or edges of social graph  200 . 
     In particular embodiments, a user node  202  may correspond to a user of the social-networking system. As an example and not by way of limitation, a user may be an individual (human user), an entity (e.g., an enterprise, business, or third-party application), or a group (e.g., of individuals or entities) that interacts or communicates with or over the social-networking system. In particular embodiments, when a user registers for an account with the social-networking system, the social-networking system may create a user node  202  corresponding to the user, and store the user node  202  in one or more data stores. Users and user nodes  202  described herein may, where appropriate, refer to registered users and user nodes  202  associated with registered users. In addition or as an alternative, users and user nodes  202  described herein may, where appropriate, refer to users that have not registered with the social-networking system. In particular embodiments, a user node  202  may be associated with information provided by a user or information gathered by various systems, including the social-networking system. As an example and not by way of limitation, a user may provide their name, profile picture, contact information, birth date, sex, marital status, family status, employment, education background, preferences, interests, or other demographic information. In particular embodiments, a user node  202  may be associated with one or more data objects corresponding to information associated with a user. In particular embodiments, a user node  202  may correspond to one or more webpages. A user node  202  may be associated with a unique user identifier for the user in the social-networking system. 
     In particular embodiments, a concept node  204  may correspond to a concept. As an example and not by way of limitation, a concept may correspond to a place (such as, for example, a movie theater, restaurant, landmark, or city); a website (such as, for example, a website associated with the social-network service or a third-party website associated with a web-application server); an entity (such as, for example, a person, business, group, sports team, or celebrity); a resource (such as, for example, an audio file, video file, digital photo, text file, structured document, or application) which may be located within the social-networking system or on an external server, such as a web-application server; real or intellectual property (such as, for example, a sculpture, painting, movie, game, song, idea, photograph, or written work); a game; an activity; an idea or theory; another suitable concept; or two or more such concepts. A concept node  204  may be associated with information of a concept provided by a user or information gathered by various systems, including the social-networking system. As an example and not by way of limitation, information of a concept may include a name or a title; one or more images (e.g., an image of the cover page of a book); a location (e.g., an address or a geographical location); a website (which may be associated with a URL); contact information (e.g., a phone number or an email address); other suitable concept information; or any suitable combination of such information. In particular embodiments, a concept node  204  may be associated with one or more data objects corresponding to information associated with concept node  204 . In particular embodiments, a concept node  204  may correspond to one or more webpages. 
     In particular embodiments, a node in social graph  200  may represent or be represented by a webpage (which may be referred to as a “profile page”). Profile pages may be hosted by or accessible to the social-networking system. Profile pages may also be hosted on third-party websites associated with a third-party server. As an example and not by way of limitation, a profile page corresponding to a particular external webpage may be the particular external webpage and the profile page may correspond to a particular concept node  204 . Profile pages may be viewable by all or a selected subset of other users. As an example and not by way of limitation, a user node  202  may have a corresponding user-profile page in which the corresponding user may add content, make declarations, or otherwise express himself or herself. A business page such as business page  205  may comprise a user-profile page for a commerce entity. As another example and not by way of limitation, a concept node  204  may have a corresponding concept-profile page in which one or more users may add content, make declarations, or express themselves, particularly in relation to the concept corresponding to concept node  204 . 
     In particular embodiments, a concept node  204  may represent a third-party webpage or resource hosted by a third-party system. The third-party webpage or resource may include, among other elements, content, a selectable or other icon, or other interactable object (which may be implemented, for example, in JavaScript, AJAX, or PHP codes) representing an action or activity. As an example and not by way of limitation, a third-party webpage may include a selectable icon such as “like,” “check in,” “eat,” “recommend,” or another suitable action or activity. A user viewing the third-party webpage may perform an action by selecting one of the icons (e.g., “eat”), causing a client system to send to the social-networking system a message indicating the user&#39;s action. In response to the message, the social-networking system may create an edge (e.g., an “eat” edge) between a user node  202  corresponding to the user and a concept node  204  corresponding to the third-party webpage or resource and store edge  206  in one or more data stores. 
     In particular embodiments, a pair of nodes in social graph  200  may be connected to each other by one or more edges  206 . An edge  206  connecting a pair of nodes may represent a relationship between the pair of nodes. In particular embodiments, an edge  206  may include or represent one or more data objects or attributes corresponding to the relationship between a pair of nodes. As an example and not by way of limitation, a first user may indicate that a second user is a “friend” of the first user. In response to this indication, the social-networking system may send a “friend request” to the second user. If the second user confirms the “friend request,” the social-networking system may create an edge  206  connecting the first user&#39;s user node  202  to the second user&#39;s user node  202  in social graph  200  and store edge  206  as social-graph information in one or more data stores. In the example of  FIG. 2 , social graph  200  includes an edge  206  indicating a friend relation between user nodes  202  of user “Amanda” and user “Dorothy.” Although this disclosure describes or illustrates particular edges  206  with particular attributes connecting particular user nodes  202 , this disclosure contemplates any suitable edges  206  with any suitable attributes connecting user nodes  202 . As an example and not by way of limitation, an edge  206  may represent a friendship, family relationship, business or employment relationship, fan relationship, follower relationship, visitor relationship, subscriber relationship, superior/subordinate relationship, reciprocal relationship, non-reciprocal relationship, another suitable type of relationship, or two or more such relationships. Moreover, although this disclosure generally describes nodes as being connected, this disclosure also describes users or concepts as being connected. Herein, references to users or concepts being connected may, where appropriate, refer to the nodes corresponding to those users or concepts being connected in social graph  200  by one or more edges  206 . 
     In particular embodiments, an edge  206  between a user node  202  and a concept node  204  may represent a particular action or activity performed by a user associated with user node  202  toward a concept associated with a concept node  204 . As an example and not by way of limitation, as illustrated in  FIG. 2 , a user may “like,” “attended,” “played,” “listened,” “cooked,” “worked at,” or “watched” a concept, each of which may correspond to a edge type or subtype. A concept-profile page corresponding to a concept node  204  may include, for example, a selectable “check in” icon (such as, for example, a clickable “check in” icon) or a selectable “add to favorites” icon. Similarly, after a user clicks these icons, the social-networking system may create a “favorite” edge or a “check in” edge in response to a user&#39;s action corresponding to a respective action. As another example and not by way of limitation, a user (user “Carla”) may listen to a particular song (“Across the Sea”) using a particular application (SPOTIFY, which is an online music application). In this case, the social-networking system may create a “listened” edge  206  and a “used” edge (as illustrated in  FIG. 2 ) between user nodes  202  corresponding to the user and concept nodes  204  corresponding to the song and application to indicate that the user listened to the song and used the application. Moreover, the social-networking system may create a “played” edge  206  (as illustrated in  FIG. 2 ) between concept nodes  204  corresponding to the song and the application to indicate that the particular song was played by the particular application. In this case, “played” edge  206  corresponds to an action performed by an external application (SPOTIFY) on an external audio file (the song “Across the Sea”). Although this disclosure describes particular edges  206  with particular attributes connecting user nodes  202  and concept nodes  204 , this disclosure contemplates any suitable edges  206  with any suitable attributes connecting user nodes  202  and concept nodes  204 . Moreover, although this disclosure describes edges between a user node  202  and a concept node  204  representing a single relationship, this disclosure contemplates edges between a user node  202  and a concept node  204  representing one or more relationships. As an example and not by way of limitation, an edge  206  may represent both that a user likes and has used at a particular concept. Alternatively, another edge  206  may represent each type of relationship (or multiples of a single relationship) between a user node  202  and a concept node  204  (as illustrated in  FIG. 2  between user node  202  for user “Edwin” and concept node  204  for “SPOTIFY”). 
     In particular embodiments, the social-networking system may create an edge  206  between a user node  202  and a concept node  204  in social graph  200 . As an example and not by way of limitation, a user viewing a concept-profile page (such as, for example, by using a web browser or a special-purpose application hosted by the user&#39;s client system) may indicate that he or she likes the concept represented by the concept node  204  by clicking or selecting a “Like” icon, which may cause the user&#39;s client system to send to the social-networking system a message indicating the user&#39;s liking of the concept associated with the concept-profile page. In response to the message, the social-networking system may create an edge  206  between user node  202  associated with the user and concept node  204 , as illustrated by “like” edge  206  between the user and concept node  204 . In particular embodiments, the social-networking system may store an edge  206  in one or more data stores. In particular embodiments, an edge  206  may be automatically formed by the social-networking system in response to a particular user action. As an example and not by way of limitation, if a first user uploads a picture, watches a movie, or listens to a song, an edge  206  may be formed between user node  202  corresponding to the first user and concept nodes  204  corresponding to those concepts. Although this disclosure describes forming particular edges  206  in particular manners, this disclosure contemplates forming any suitable edges  206  in any suitable manner. 
     The social graph  200  may further comprise a plurality of product nodes. Product nodes may represent particular products that may be associated with a particular business. A business may provide a product catalog to the consumer-to-business service  110  and the consumer-to-business service  110  may therefore represent each of the products within the product in the social graph  200  with each product being in a distinct product node. A product node may comprise information relating to the product, such as pricing information, descriptive information, manufacturer information, availability information, and other relevant information. For example, each of the items on a menu for a restaurant may be represented within the social graph  200  with a product node describing each of the items. A product node may be linked by an edge to the business providing the product. Where multiple businesses provide a product, each business may have a distinct product node associated with its providing of the product or may each link to the same product node. A product node may be linked by an edge to each user that has purchased, rated, owns, recommended, or viewed the product, with the edge describing the nature of the relationship (e.g., purchased, rated, owns, recommended, viewed, or other relationship). Each of the product nodes may be associated with a graph id and an associated merchant id by virtue of the linked merchant business. Products available from a business may therefore be communicated to a user by retrieving the available product nodes linked to the user node for the business within the social graph  200 . The information for a product node may be manipulated by the social-networking system as a product object that encapsulates information regarding the referenced product. 
       FIG. 3A  illustrates an embodiment of a user interface  300  with a message interaction display  310  with messaging bot invocation controls  315 . 
     A client device  320  may correspond to any device used to access a consumer-to-business communication system  100 . While in the illustrated embodiment of  FIG. 3A  the client device  320  resembles a smartphone device, it will be appreciated that the techniques described herein may be used with any type of device. The user interface  300  may generally correspond to a display of a message thread for the messaging system  140 . 
     A messaging client may display a messaging client header  305 . The messaging client header  305  may comprise a title for a message thread, such as the name of one or more users participating in the message thread, which may be selected according to real name, nick names, or other name information. The messaging client header  305  may comprise a control to return a user to an inbox view for the messaging client. An inbox view control may be augmented with a number of recent message threads with unread messages. 
     The user interface  300  for a message thread may include composition controls  322 . Many, most, or nearly all of the composition controls  322  may empower access to and use of interface controls for the performance of various tasks, such as text entry, media selection, emoji selection, camera use, a social approval icon, etc. The controls may include text entry controls empowering the entering of text for the composition of text-based messages. The controls may include hardware controls. In some embodiments, controls may be touchscreen-based controls. 
     The user interface  300  for the message thread may comprise a message interaction display  310 . The message interaction display  310  may comprise the messages exchanged within the message thread. The message interaction display  310  may be iteratively updated as additional messages are added to the message thread by the participants in the message thread. Messages may be displayed in association with an avatar for the user. 
     A messaging client and/or messaging system  140  may detect messaging content for use in selecting and configuring one or more messaging bots. Extracted messaging content may generally correspond to a word, phrase, sentence, sequence or interchange of messages, or other element of a message thread that a messaging system  140  associates with a potential action, option, or other suggestion. The messaging system  140  using identified messaging content may invoke suggested services, such as suggested messaging bots, related to the messaging content. Messaging content for extraction may be determined based on predetermined and pre-assigned associations between words and/or phrases and various suggestions, or may be automatically determined based on natural language programming techniques. 
     Detecting potential user interest in interacting with a messaging bot may invoke the display of messaging bot invocation controls  315 . The messaging client may retrieve and display a plurality of suggested services, such as may correspond to suggests messaging bots, in a plurality of triggered messaging bot invocation controls  315 . In some embodiments, the plurality of suggested services may be automatically displayed on response to the messaging client and/or messaging system  140  detecting a relevant context. The messaging bot invocation controls  315  may comprise a plurality of messaging bot options. A messaging bot invocation control may comprise a particular messaging bot associated with a particular service. 
     The messaging bot invocation controls  315  may comprise suggestions for services, as may be represented by messaging bots. The messaging bot invocation controls  315  may comprise a ranked list of suggested messaging bots. Suggested messaging bots may be determined based on a variety of techniques and based on a variety of factors. The ranking of the suggested messaging bots may be represented in the ordering of the messaging bot invocation controls  315 , with higher-ranked messaging bots displayed more prominently and lower-ranked messaging bots displayed less prominently. For instance, some lower-ranked messaging bots may be arranged such that they are completely or partially off-screen and only revealed (or fully revealed) if the user navigations through the messaging bot invocation controls  315 . 
     Information may be extracted from the content, or a portion of the content, of the messaging interaction embodied in a message thread. In some cases, a recent portion of the message thread may be used, such as by detecting a current period of engagement with the message thread and analyzing the message thread for that current period. The recent portion of a message thread may be defined according to a variety of techniques. In some cases, the recent portion may be defined according to a predefined length of time, with the recent portion being the segment of the thread exchanged during an extent of time spanning a length equal to the predefined length of time and concluding at the current time. In some cases, the recent portion may be determined as spanning a variable length, such as by detecting the most recent break in conversation of sufficient length, which may be predefined, to indicate temporary disengagement with the message thread. For example, the recent portion of the message thread may be the maximum extent of the thread concluding at the current time that does not include any gap in conversation longer than one hour. Other techniques for defining a recent portion of a thread may be used. 
     Selecting a messaging bot invocation control of the plurality of messaging bot invocation controls  315  may invoke an interface for interaction with that particular selected messaging bot. 
     In some embodiments, a message thread may be a multi-user message thread in which multiple participants engage in a message interaction. However, in an alternative embodiment, the message thread may be a bot-request thread in which a user engages directly and purposefully with a system that can recommend and guide the user to various messaging bots. A user may select a bot-request thread from a list of bots, engage with a bot-request engine to receive recommended bots, and then engage with the bots in the bot-request thread. For example, rather than asking “Want to get dinner tonight? I&#39;m thinking Chinese food.” a user might submit “I&#39;d like to get dinner tonight and am thinking Chinese food.” in the bot-request thread, with the bot-request system recommending messaging bots to the user in response. The messaging bot invocation controls  315  may then be presented, not as a response to the detection of an opportunity for recommendations implicit in a user-to-user interaction, but instead as a response to a direct query by the user. 
     In another alternative embodiment, a request for assistance from a messaging bot may be directly invoked within a user-to-user message thread. A bot request may be made by directly addressing the bot-suggestion system. Directly addressing the bot-suggestion system may be performed using a variety of techniques. For instance, the bot-suggestions system may be addressed by prefixing a text-based request with a text segment indicating that the bot-suggestion system is being addressed. For example, a user might enter “@M I&#39;d like to get dinner tonight and am thinking Chinese food,” with the “@M” text segment invoking the bot-suggestion system. Alternatively or additionally, a control may be provided as part of the composition controls  322  empowering addressing of the bot-suggestion system with the user-to-user message thread. In some embodiments, where the bot-suggestion system is directly invoked, the invocation of the bot-suggestion system, any responses by the bot-suggestion system (such as messaging bot invocation controls  315  or other responses), or interactions with the messaging bot may only be shown to the user of the client device  320  that invokes the bot-suggestion system and any bots, with the messaging system  140  refraining from providing these interactions to other client devices. This creates a side-conversation within a user-to-user message thread between the invoking user and the bot-suggestion system and messaging bots that is private from any other participants in the thread. However, in other embodiments, other client devices, and therefore their users, may be provided some or all of these interactions. 
       FIG. 3B  illustrates an embodiment of a user interface  325  with a messaging bot menu  335 . 
     A messaging bot menu  335  for a particular messaging bot may be displayed in response to a messaging bot invocation control for that messaging bot being selected by a user of a client device  320 . The messaging bot menu  335  may be displayed in association with the messaging thread from which it is invoked. 
     The messaging bot menu  335  is a display element specifically associated with a particular messaging bot and empowers a user to interact with an interface for the messaging bot within the context of the message thread from which it is invoked. The user of the client device  320  may move into the messaging bot menu  335 , interact with the messaging bot menu  335  to interact with the messaging bot, back out of the messaging bot menu  335  to re-engage with the messaging conversation in the message thread, move back into the messaging bot menu  335  to re-engage with the messaging bot, move between different messaging bot menus, and generally dynamically interact with messaging bot menus within the context of the message thread so as to select and interact with a messaging bot while retaining a connection to an ongoing messaging conversation. 
     Messaging bot invocation controls  330  may be displayed adjacent to the messaging bot menu  335 . The messaging bot invocation controls  330  may be substantially similar to the messaging bot invocation controls  315  displayed adjacent to a messaging conversation, but relocated to a top portion of the screen of the client device  320 . The relocated messaging bot invocation controls  330  may be tabs for selecting between the various messaging bot menus. As such, selecting a currently-unselected messaging bot invocation control may transition the messaging client to display the messaging bot menu for the now-selected messaging bot invocation control. The particular messaging bot invocation control associated with the current messaging bot menu  335  may be displayed with a distinct visual style, so as to indicate that the messaging bot for that messaging bot invocation control currently has the active messaging bot menu  335 . Re-selecting the control for the currently-active messaging bot menu  335  may minimize the messaging bot menu  335  to empower the user to return to the view of the messaging bot conversation in a messaging interaction display  310 . 
     The messaging bot menu  335  may comprise a plurality of customization options  345 . These customization options  345  comprise settings configuring a messaging bot as set by controls for the messaging bot provided as part of the messaging bot menu  335 . Customization options  345  may be initially set automatically based on the context of the message thread, based on the content of the specific messaging interaction prompting the display of the messaging bot invocation controls  315 , based on user information for the message thread and/or the specific messaging interaction, and/or according to other analysis of the context of the messaging bot menu  335 . These customization options  345  may then be retained by the user or modified using the controls of the messaging bot menu  335 . 
     In general, the messaging bot menu  335  is configured based on the customization options  345 , whether customization options  345  set automatically or set manually by the user of the client device  320 . In some instances, a messaging bot menu  335  may include one or more menu entries. For example, for a messaging bot menu  335  designed for configuring, displaying, and selecting restaurant recommendations, a menu entry  340  may correspond to a particular restaurant. A menu entry  340  may include a name, location, pricing information, performance information, and other information relating to the menu entry  340 . A menu entry  340  may include one or more controls. For example, a control for a restaurant menu may empower the selection of both a restaurant and a particular available reservation time for the restaurant. In these instances, the menu entries are determined at least in part based on the customization options  345 . The menu entries may also be determined in part on additional information, such as information relating to a message thread or participants in a message thread. 
       FIG. 3C  illustrates an embodiment of a user interface  350  with a messaging bot menu with a multi-user request control  355 . 
     In some cases, an interface for interacting with the consumer-to-business service  110  may be distributed across multiple client devices, such that multiple users on multiple client devices contribute to the configuration of a service request. A primary user may initiate an interaction with a messaging bot and use a primary interface for interacting with that messaging bot. However, the other users in a message thread may be offered the opportunity to engage with the messaging bot in concert with the primary user and any other secondary users. 
     In some cases, an interface for a messaging bot, or other agent using the consumer-to-business service  110  to communicate with users, may be instantiated across multiple client devices based on the selection of the agent by a primary user. In other cases, an agent may initially instantiate a single-user interface on a single client device and optionally or only eventually instantiate on multiple client devices. The interface on the instantiating client device may be a primary multi-user interface being the primary or controlling interface for the multi-user interface. 
     A multi-user request control  355  may be used to instantiate secondary user interfaces on secondary client devices. The secondary client device may be identified as those being currently used by other participants in a group message thread. The multi-user request control  355  may initiate the instantiation of secondary user interface on one or more other client devices in order to configure a service request. In the illustrated embodiment, the multi-user request control  355  instantiates a user interface on the secondary client device asking the users of the secondary client devices to indicate whether or not they should be included in the count of people who will be participating in the requested service. 
       FIG. 3D  illustrates an embodiment of a user interface  360  with a secondary multi-user interface  365 . 
     The user interface  360  may be displayed on a secondary client device  370 . A secondary client device  370  may comprise a client device used by a participant in a message thread other than user who initiated contact with a messaging bot. 
     The user interface  360  for the secondary client device  370  may include a secondary multi-user interface  365  instantiated on the secondary client device  370  based on a primary multi-user interface on a primary client device. The secondary multi-user interface  365  may include information specified in the primary multi-user interface. For example, for a restaurant reservation, the primary multi-user interface may determine the specific restaurant, date, and time for the reservation. The secondary multi-user interface  365  may include a multi-user control  368  of one or more multi-user controls. The multi-user control  368  on a secondary multi-user interface may empower the participant in the message thread to contribute to the configuration of a service request. For example, where a service request is being configured, one or more multi-user controls may empower a user to register whether or not they want to be included in the service being requested. 
     The user interface  360  for a message thread may include composition controls  369 . Many, most, or nearly all of the composition controls  369  may empower access to and use of interface controls for the performance of various tasks, such as text entry, media selection, emoji selection, camera use, a social approval icon, etc. The controls may include text entry controls empowering the entering of text for the composition of text-based messages. The controls may include hardware controls. In some embodiments, controls may be touchscreen-based controls. 
       FIG. 3E  illustrates an embodiment of a user interface  380  for a messaging bot menu  390  for a configured service request including a multi-user contribution element  395 . 
     A messaging bot menu  390  may advance to a point where a service request has been sufficiently configured as to allow a service request. Once the messaging bot menu  390  has reached this state, a service request control  385  may be displayed. The service request control  385  empowers a user to request that a service be performed. 
     The messaging bot menu  390  for a configured service request may include options configured based on the multi-user interface, where at least a portion of the configured options are based on the participation in the multi-user interface by users of the one or more secondary multi-user interfaces. The configured options may include a multi-user contribution element  395 , where the multi-user contribution element  395  reflects user interface interactions on one or more secondary client devices other than the primary client device  320  for the multi-user interface. In the illustrated embodiment, the multi-user contribution element  395  reflects the results of secondary multi-user interfaces collecting information on whether participants in a message thread will join a group reservation. 
       FIG. 4A  illustrates an embodiment of a user interface  400  with a message interaction display  410  with administrative text  415  communicating a service request. 
     Once a user has selected a service request control  385 , or otherwise requested a service from a messaging bot, the messaging bot may provide administrative text  415  to the messaging system  140 , the administrative text  415  communicating the configured service. The administrative text  415  is then provided by the messaging system  140  to the client device  320  for display as part of the messaging interaction display  410 . The administrative text  415  may also be distributed to other client devices belonging to the user and to client devices associated with other participants in the message thread. The administrative text  415  may include text, images, controls, or any other element. The administrative text  415  may be customized based on the viewer. For example, the administrative text may identify the user requesting a service differently to that user and to other users 
       FIG. 4B  illustrates an embodiment of a user interface  425  with a message interaction display  435  with administrative text  440  communicating a service request customized to a secondary user of a multiple-user interface. 
     The administrative text  440  is provided to the message interaction display  435  on a secondary client device  370 . Administrative text may be customized to each client device for the participants in a message thread. The administrative text  440  for a secondary client device  720  may communicate the service request that the user of the secondary client device  370  participated in the configuration of. The administrative text  440  for a secondary client device  370  may reflect the specific contributions of the secondary client device  370 . For example, for a request for a service, the administrative text  440  may reflect whether the user opted to participate in the service request. In some embodiments, a user that declines to participate in a service request may be exempted from receiving the administrative text, such that administrative text is sent to those and only those users that opted to participate in the service request. 
       FIG. 5  illustrates an embodiment of a consumer-to-business communication system  100  determining a user intent  515  based on a messaging interaction. 
     A messaging system  140  may comprise a plurality of components. In some embodiments, these plurality of components may be distributed among a plurality of servers. In other embodiments, a single server may implement the plurality of components. In some embodiments, a plurality of servers may be executed by a single server device. In other embodiments, the plurality of servers may be executed by a plurality of server devices. In some embodiments, multiple instances of the various components and various servers may be executed to provide redundancy, improved scaling, and other benefits. Similarly, a client device may execute a plurality of components as part of a messaging client. 
     A client device may communicate with other devices using wireless transmissions to exchange network traffic. Exchanging network traffic, such as may be included in the exchange of messaging transactions, may comprise transmitting and receiving network traffic via a network interface controller (NIC). A NIC comprises a hardware component connecting a computer device, such as client device, to a computer network. The NIC may be associated with a software network interface empowering software applications to access and use the NIC. Network traffic may be received over the computer network as signals transmitted over data links. The network traffic may be received by capturing these signals and interpreting them. The NIC may receive network traffic over the computer network and transfer the network traffic to memory storage accessible to software applications using a network interface application programming interface (API). The network interface controller may be used for the network activities of the embodiments described herein, including the interoperation of the messaging client and messaging servers through network communication. For example, the messaging client transmitting or receiving messages to or from a client front-end server  535  may be interpreted as using the network interface controller for network access to a communications network for the transmission or reception of information. 
     A messaging client may comprise a user interface component  523 . A user interface component  523  may be generally arranged to display user interfaces to a user of a client device and to receive user commands for the messaging client for the client device. A messaging client may comprise a client messaging component  526 . A client messaging component  526  may be generally arranged to conduct messaging interactions on the behalf of the messaging client via communication with the client front-end server  535 . 
     A client front-end server  535  may be generally arranged to act as a network access point to the messaging system  140  for client devices such as sender client device  520 . The client front-end server  535  may comprise a messaging component  530 , the messaging component  530  generally arranged to act as a network access point to messaging services for the messaging system  140 . The messaging component  530  may receive messages from client devices and add the messages to message queues. 
     A message queue  580  may be specifically associated with the user of sender client device  520 , such as by being uniquely associated within the messaging system  140  with a user account for the user of sender client device  520 . The message queue  580  may be a single queue used for all messaging endpoints used by this user. The message queue  580  may comprise a representation of updates in a strict linear order. The message queue  580  may be organized as a data unit according to a variety of techniques. The message queue  580  may be stored in semi-persistent memory, persistent storage, both semi-persistent memory and persistent storage, or a combination of the two. The message queue  580  may be organized according to a variety of data structures, including linked lists, arrays, and other techniques for organizing queues. The message queue  580  may generally comprise a first-in-first-out (FIFO) queue in which no update will be removed or retrieved from the queue before any updates that were received prior to it. 
     The messaging system  140  may comprise one or more worker servers, such as worker servers  545 ,  555 ,  565 . In general, the messaging system  140  may comprise a plurality of worker servers that may be assigned to various tasks. A worker server  545  may comprise a message queue monitoring component  540 , the message queue monitoring component  540  arranged to monitor updates, such as may comprise messages, in the message queue  580  and other message queues of the messaging system  140  for various flags, indicators, and other information. A worker server  55  may comprise an interaction processing component  550 , the interaction processing component  550  operative to manage the generation of a user intent  515  based on the contents of a messaging interaction. A worker server  565  may comprise a natural-language processing component  560 , the natural-language processing (NLP) component  560  operative to use natural-language processing techniques to analyze messaging interactions to analyze messaging interactions and generate user intent  515  based on the messaging interactions. The NLP component  560  may comprise a natural-language machine-learning component operative to use natural-language machine-learning techniques to improve its NLP operations. 
     The interaction processing component  550  may interface with the NLP component  560 . The NLP component  560  performs natural-language processing for the consumer-to-business communication system  100 . The performance of natural-language processing may include the analysis the contents of a messaging interaction to determine an intent of the messaging interaction. The intent represents a goal being sought to by the messaging interaction. For instance, people discussing where to get dinner may have an intent of “dinning,” “eating,” “restaurant,” or other related term. The interaction processing component  550  may provide the content of a messaging interaction, including one or more messages, to the NLP component  560  and the NLP component  560  replies with the user intent  515 , or multiple user intents, it detects for that interaction. The NLP component  560  may be implemented using known natural language processing (NLP) and machine learning (ML) techniques. 
     The message queue monitoring component  540  monitors a messaging interaction. This messaging interaction is exchanged via a messaging system  140 . This messaging interaction involving at least one client device, such as a sender client device  520  and/or a recipient client device  590 . A message  510  may be sent from a client messaging component  526  of a messaging client on a sender client device  520 . This message  510  is associated with a message thread, the message thread involving two or more participants, including the user of the sender client device  520 . This message  510  comprises a portion of the messaging interaction of a message thread. 
     The message  510  is received by the messaging component  530  of the client front-end server  535  and is added to a message queue  580  associated with the sender. The message  510  is distributed using the message queue  580  to the recipient client device  590 . The message queue monitoring component  540  also receives the message  510  and provides it to the interaction processing component  550 . 
     The interaction processing component  550  provides the message  510  to the NLP component  560  and receives the user intent  515  in response. The message  510  may be provided to the NLP component  560  as part of a repository of multiple messages, so as to empower the analysis of a messaging interaction as a whole. As such, the interaction processing component  550  determines determine a user intent for the messaging interaction by submitting at least a portion of the messaging interaction to a NLP component  560  and receiving the user intent  515  from the NLP component  560  in response to submitting at least the portion of the messaging interaction to the NLP component  560 . The interaction processing component  550  may therefore detect the user intent  515  for the messaging interaction by using the NLP component  560 . 
       FIG. 6  illustrates an embodiment of a consumer-to-business communication system  100  determining a messaging bot options configuration based on a user intent  515 . 
     In some embodiments, a consumer-to-business communication system  100  may include a bot management component  660  that acts as an access point to messaging bot services for the consumer-to-business communication system  100 . The bot management component  660  may act as an intermediary between the servers of the messaging system  140  and one or more internal and/or external bot execution servers. The bot management component  660  may comprise a bot framework generally arranged to provide an accessible framework to the messaging bot system. The bot management component  660  may be executed by a worker server  665  substantially similar to the worker servers  545 ,  555 ,  565  described with reference to  FIG. 5 . 
     In some cases, messaging bots may be executed by servers external to the consumer-to-business communication system  100 , such as an external bot server operated by the service associated with the bot. A bot management component  660  may determine an external bot server for the service associated with the messaging bot. The bot management component  660  may submit messages to the messaging bot by sending the messages to the external bot server associated with the messaging bot. In some embodiments, submitting messages may comprise extracting message content and transmitting the message content to the external bot server using a bot server interaction application programming interface (API). Bot messages from the messaging bots may similarly be received by the bot management component  660  from an external bot server. 
     In other cases, messaging bots may be executed by the servers of the consumer-to-business communication system  100 . The bot management component  660  may determine a hosted bot server for the service associated with a messaging bot. A hosted bot server may comprise a bot server maintained by the provider of the consumer-to-business communication system  100 . The bot management component  660  may submit messages to the messaging bot by sending the messages to the hosted bot server associated with the messaging bot and may receive messages from the messaging bot by receiving them from the hosted bot server. 
     The bot management component  660  receives the user intent  515  from the interaction processing component  550  and determines a messaging bot options configuration  610  for the client device based on the user intent  515 . The messaging bot options configuration  610  configures one or more client devices with interface controls empowering the one or more users of the one or more client devices to engage with one or more messaging bots. 
     The bot management component  660  then sends the messaging bot options configuration  610  to the sending client device  520  in response to the change in the context of the messaging interaction enacted by the message  510  being sent by the sender client device  520 . Sending the messaging bot options configuration  610  to the sender client device  520  may comprise adding the messaging bot options configuration  610  to a message queue  580 , such as a message queue  580  associated with a message thread in which the messaging interaction is occurring. The messaging bot options configuration is then distributed to the sender client device  520  by a server messaging component  530  retrieving the messaging bot options configuration  610  from the message queue  580  and delivering it to the client messaging component  526 . The messaging bot options configuration  610  may be distributed to every user and client device involved in the messaging interaction, such as every client device belonging to every participant in the message thread. As such, a recipient client device  590  for the message  510  may also receive the messaging bot options configuration  610  generated in response to the message  510 . In some embodiments, a messaging bot options configuration  610  may be distinctly configured for a primary client that initiated a messaging bot interaction and one or more secondary clients that are present in the message thread but did not initiate the messaging bot interaction. 
     A messaging interaction comprises a plurality of exchanged messages. This plurality of exchanged messages includes a most-recent message  510  of the message interaction. A message package sent to the client device via the messaging component  530 , with this message package associated with the most-recent message  510 , may be used to deliver the messaging bot options configuration  610 . A message package sent to the sender client device  510  may be used to confirm receipt of the message  510  by the messaging system  140 , may be used to report delivery of the message  510  to one or more recipient users, and/or may be used to report that a recipient user has viewed the message  510 . A message package sent to a recipient client device  590  may comprise both the message  510 , as may be the initial delivery of the message  510  to the recipient client device  590 . In either case, the message package may additionally include the messaging bot options configuration  610 . 
     In general, the message  510  may be sent to every client device related to a message thread, including the client device used to send the message  510 . This message  510  may be augmented in the package used to deliver the message  510  with the messaging bot options configuration  610 . The messaging bot options configuration  610  configures the messaging interface for the messaging client in displaying a message thread with controls empowering interactions with a messaging bot. Therefore, the bot management component  660  is operative to send a message package to the client device, the message package associated with the most-recent message  510 , such that the message package comprises the messaging bot options configuration  610 . This message package updates the client device with the most-recent message  510 . In some cases, this most-recent message  510  is received from a different client device than the one receiving the message package. In some cases, the message package  510  may acknowledge receipt of the most-recent message from the client device. 
     In some instances, the messaging bot options configuration  610  may be a messaging bot menu associated with a messaging bot. The messaging bot menu is customized based on the user intent  515 . The messaging bot menu may consist of a plurality of user-customizable options. Customizing the messaging bot menu based on the user intent may consist of pre-filling one or more of the user-customizable options based on the user intent. The messaging bot menu may comprise a later stage or second stage of providing messaging bot options configurations to a client device, with a first stage being messaging bot options configurations and the second stage being a customized messaging bot menu provided in response to an activation of a messaging bot invocation control. 
     In some instances, the messaging bot options configuration  610  may consist of a plurality of messaging bot invocation controls. Each of the messaging bot invocation controls is associated with a different messaging bot. This plurality of messaging bot invocation controls is selected based on the user intent  515 . The user intent  515  may reflect a user-expressed goal or subject of a messaging interaction. Various messaging bots may be associated with this user intent  515 . For instance, messaging bots may be assigned one or more user intents during a registration with the consumer-to-business communication system  100 . A plurality of messaging bots associated with the user intent  515  are determined and provided to a client device. In some instances, the plurality of messaging bot invocation controls may be additionally selected based on a user context. A user context may consist of one or more of a user location and a local user time, without limitation. The plurality of messaging bot invocation controls may additionally be selected based on a user profile, such as based on user service preference information stored in the user profile. 
     After the delivery of a messaging bot options configuration  610  comprising messaging bot invocation controls, the user of the client device may select one of the messaging bot invocation controls. The messaging component  550  may then receive a user messaging bot selection of a selected messaging bot invocation control of the plurality of messaging bot invocation controls from the client device. A selected messaging bot invocation control is associated with a selected messaging bot. The user messaging bot selection is passed to the bot management component  660 , which then sends a messaging bot interface to the client device in response. This messaging bot interface may comprise, in some instances, a messaging bot menu. 
     To process the messaging bot selection, the bot management component  660  sends a messaging bot invocation message to a bot server associated with the selected messaging bot. The messaging bot invocation message includes the user intent  515  to empower the messaging bot to configure itself according to the user intent  515 . In some instances, the bot server may be hosted by the consumer-to-business communication system  100 . In other instances, the bot server may be externally hosted, such as by the developer of the messaging bot. The bot management component  660  then receives a messaging bot interface specification from the bot server in response to the messaging bot invocation message, where this messaging bot interface is based on the messaging bot interface specification. 
     The messaging component  530  may instantiate a multiple-user interface on a plurality of client devices. The instantiating indicates display of a at least a portion of the multiple-user interface on each of the plurality of client devices. In response, a messaging client on each of the plurality of client devices displays at least a portion of the multiple-user interface. The messaging component receives a user-interface interaction from a first client device of the plurality of client devices and updates the multiple-user interface on the plurality of client devices based on the user-interface interaction. The messaging component  530  may receive a multiple-user application initiation from an initiating client device of the plurality of client devices and instantiate the multiple-user interface on the plurality of client devices in response to the multiple-user application initiation. 
     A multiple-user application initiation may be associated with a message thread for a messaging system. The message thread may be associated with a plurality of participant user accounts, with the plurality of participant user accounts associated with the plurality of client devices. The multiple-user interface is instantiated on the plurality of client devices based on the plurality of participant user accounts being associated with the plurality of client devices for the plurality of participant user accounts in the message thread. 
     The messaging component  530  may update the multiple-user interface on the plurality of client devices by distributing a user-interface update object based on the association between the plurality of participant user accounts and the message thread. The user-interface update object may be distributed using a message queue  580 , with the object queued for distribution to the plurality of client devices. 
     An initiating client device may be associated with an initiating user account of the plurality of participant user accounts. The initiating user account may be used as a primary account for interaction with a bot, where a requested service is requested as being a request from the initiating user account. The messaging component  530  may receive a service request via the multiple-user interface, the service request comprising input from the plurality of participant user accounts, and submit the service request to a messaging bot. The service request is submitted by the initiating user account as being associated with the initiating user account. The service request is sent to the messaging bot as originating with the initiating user account. 
     The plurality of participant user accounts may comprise the initiating user account and one or more contributor user accounts other than the initiating user account. The input comprising the service request may comprise a group service configuration from the initiating user account and one or more individual service configurations from the one or more contributor user accounts. For instance, each participating user may indicate a particular portion of the service they&#39;d like to receive. For example, a participating user may select a food order, transportation order, or other service order. As such, the one or more individual service configurations may comprise one or more option selections. Alternatively, the one or more individual service configurations may comprise one or more service-request participation confirmations, such that a participant count for a requested service is determined based on the one or more service-request participation confirmations. 
     A multiple-user application may be used to generate a service request with an associated cost. In some cases, the messaging component  530  may receive a cost-split request from the initiating user account and send the cost-split request to the one or more contributor user accounts. The cost-split request may be sent via the message queue  580 . The cost-split request may be operative to initiate a financial transfer from the one or more contributor user accounts. In some instances, the financial transfer may be used to reimburse the initiating user account. Alternatively, the financial transfer from one or more participant user accounts may be pooled to pay for the requested service. 
       FIG. 7  illustrates an embodiment of a consumer-to-business communication system  100  determining a messaging bot options configuration  610  based on a user information exchange  730  and a bot information exchange  795 . 
     The user-to-bot conversation may be mediated by a bot management component  660 . The bot management component  660  may be coupled to messaging servers for a messaging system  140 . The messaging servers may perform the sending and receiving of messages between the bot management component  660  and the user client  720 . The messaging servers may perform the sending and receiving of information between the bot management component  660  and the bot application  790 , or a bot-application front-end may be used, such as business portal  160 . 
     A user client  720  may comprise a messaging client, a dedicated client for access to the bot application  790  or a plurality of bot applications for a plurality of bots  190 , or any other client including messaging functionality. The user client  720  may execute on the client device. The user client  720  may engage in a user information exchange  730  with the bot management component  660  using a client communication component  740 . The client communication component  740  may provide a client front-end to the bot management component  660 , which may be mediated by the transmission of messages by a messaging system  140 . The user information exchange  730  may comprise the sending of user-composed messages from the user client  720  to the bot management component  660  and the sending of bot messages from the bot management component  660  to the user client  720 . The user information exchange  730  may further include additional user information in addition to user messages, such as, without limitation, social-networking information for one or more users, bot interaction history information for one or more users, or other user information. 
     A bot application  790  may comprise a software program, such as may execute on a developer computer system or may be hosted by the consumer-to-business communication system  100 . The bot application  790  may engage in a bot information exchange  795  with the bot management component  660  via a bot application interface component  780 . The bot application interface component  780  may act as a front-end to the bot management component  660  and/or messaging system for bot applications. The bot information exchange  795  may comprise the submission of example conversations to the bot management component  660  and the performance of bot API calls by the bot application interface component  780  with the bot application  790 . The bot information exchange  795  may comprise the submission of a bot capability catalog to the bot management component  660  and/or other information exchange for the selection of a bot for suggestion to a user. 
     The bot application interface component  780  receives a plurality of bot capability catalogs  770  for a plurality of bots at a bot-service system. The bot-service system may comprise a component of a messaging system  140 . The bot capability catalog for a particular bot application  790  may be received as at least part of a bot information exchange  790  with that bot application  790 . The bot application interface component  780  provides the bot capability catalogs  770  to the interaction processing component  760  as part of a bot information exchange  795  for each of the bots. 
     Each of the plurality of bot capability catalogs  770  expresses bot capability in natural language for an associated bot. A particular bot is built to provide a particular service or set of services. These services may be expressed in natural language, such as English, Spanish, or any other language. These services may use natural language to describe in human-readable terms what service or services the bot may provide to the user. Various human-readable bot capability descriptions may be used. For example, a developer may describe a food-delivery-ordering bot with the sentence “This bot can help find and order food for delivery in the San Francisco area.” One or more of the plurality of bot capability catalogs  770  may express bot capability in one or more example user prompts. An example user prompt is an example of a user statement, user interaction, or other user behavior that the developer indicates should prompt an interaction with the bot, such as suggesting the bot to a user. For example, an example user prompt may be the human-readable natural-language sentence, “What do you think about ordering something in?” As illustrated in the example sentence, an example user prompt may comprise a portion of a user-to-user exchange, such that a user may be suggested bots to accompany the natural flow of their conversation with one or more other users. 
     The bot application interface component  780  may receive one or more bot capability catalogs of the plurality of bot capability catalogs  770  via a developer bot-configuration interface. As such, the natural-language expression of the bot capabilities may be developer-written bot capability descriptions. Further, the developer-written bot capability descriptions may be developer-written example user prompts. In some cases, a developer may receive logs of user interactions with their bot. The developer may then mark a user prompt as an example user prompt that should, moving forward, be used as an example of a user statement that should prompt interaction with the bot. As such, at least some bot capability descriptions may be developer-approved user-generated example user prompts. In some cases, a developer may edit a user-generated prompt before using the user-generated prompt as an example user prompt for the bot. 
     The client communication component  740  receive a user service prompt from a user client device. A user service prompt is any indication in relation to a user that it may be appropriate to suggest a bot to the user. The user service prompt may be expressed in natural language. This natural language may comprise written text, spoken word, visual gestures or signs (e.g., sign language), or any other use of natural language. In some cases, the user prompt may be received via a messaging client on the user client device. The user prompt may comprise a portion of an interaction between two or more users. This interaction may comprise a messaging interaction performed using a messaging client. 
     In some cases, the user prompt may comprise a bot interaction result. A bot interaction result is the result of an interaction between one or more users and one or more bots. For example, a user making a restaurant reservation via a bot is a bot interaction result. A bot interaction result may be recognized as a user prompt in order to encourage chains of interactions with bots. For instance, a user may be suggested transportation-service bots in response to a bot interaction result of making an appointment, reservation, or other plan to travel to a particular location. For example, in response to a restaurant reservation being made via a bot, the user may be suggested a ride-sharing bot without any other user action (such as expressing a specific interest in transportation) by the user. 
     The interaction processing component  760  determines one or more selected bots of the plurality of bots by matching the user service prompt against the plurality of bot capability catalogs  770 . In some cases, the consumer-to-business system  100  may be configured to, where possible, suggest multiple bots to provide options to the user. As such, the interaction processing component  760  may determine two or more selected bots of a plurality of bots. 
     The client communication component  740  then identifies the one or more selected bots to the user client device in response to receiving the user service prompt from the user client device as part of the user information exchange  730 . The one or more selected bots may be identified to the same messaging client on the user client device that was used to detect the user prompt. 
     The interaction processing component  760  may use an NLP component  560  to match natural-language user prompts to natural-language bot capabilities. The interaction processing component  760  submits the plurality of bot capability catalogs  770  to the NLP component  560  and receives a bot capability table  710  from the NLP component  560  in return. The interaction processing component  760  submits the user prompt to the NLP component  560  and receives a user intent from the NLP component  560  in return. The interaction processing component  760  then determines the one or more selected bots by comparing the user intent to the bot capability table. 
     This comparison may be performed using numerical vectors that represent an inferred meaning of a natural language expression in an abstracted numerical form. The bot capability table  710  may represent the plurality of bot capability catalogs as a plurality of bot capability vectors. The plurality of bot capability vectors encode the natural-language bot capabilities in an abstracted numerical form. In some embodiments, each bot may be represented by a single bot capability vector, such that even a plurality of natural-language bot capability expressions are combined into a single numerical vector. However, in other embodiments, bots may be represented by multiple vectors, such as by having a distinct vector for each of a plurality of bot capability expressions (e.g., a plurality of example user prompts) in the bot capability table  710 . The translation from natural-language bot capabilities to non-natural-language bot capability vectors is performed by the NLP component  560  using natural-language-to-vector techniques. 
     Similarly, the user intent may represent the user prompt as a user intent vector. The translation from a natural-language user prompt to a non-natural-language numerical vector is performed by the NLP component  560  using natural-language-to-vector techniques. 
     Comparing the user intent to the bot capability table  710  therefore may comprise performing a similarity search of the plurality of bot capability vectors based on the user intent vector. The interaction processing component  760  may search the bot capability table  710  using the vectorized user intent as a search term. The similarity search may be based on a cosine similarity comparison. The bot capability table  710  may be organized to empower efficient cosine similarity comparisons, such that the plurality of bot capability vectors are searched without a direct cosine similarity calculation being performed between all of the plurality of bot capability vectors and the user intent vector. The interaction processing component  760  selects one or more bots based on the similarity search determining that the one or more bot capability vectors for the one or more bots are similar to the user intent vector. 
     The interaction processing component  760  may select a predefined number of bots by selecting the predefined number of bots with bot capability vectors with the highest similarity to the user intent vector. Alternatively, the interaction processing component  760  may select a selection of bots by selecting those bots with bot capability vectors that exceed a predefined similarity threshold to the user intent vector. These techniques may be used in combination, such as by selecting those bots with bot capability vectors that exceed a predefined similarity threshold to the user intent vector without exceeding the predefined number of bots, such that if more bots exceed the predefined similarity threshold than allowed by the predefined number, the predefined number of bots with the highest similarity to the user intent are selected. As such, the selected bots may be those that exceed the predefined similarity threshold up to the predefined number of bots. The selected bots may be ranked for display on a client device according to the degree of similarity, with higher-similarity bots ranked higher than lower-similarity bots. 
     In some embodiments, the selected bots may be filtered based on user-specific information to improve the selection and ranking of bots for a specific user. As such, the interaction processing component  760  may determine two or more filtered bots of the two or more selected bots based on bot relevancy and identify the two or more filtered bots to the user client device in response to receiving the user service prompt from the user client device. Bot relevancy corresponds to the predicted relevancy of a particular bot to a particular user. Filtering the selected bots for bot relevancy to a particular user, or to the plurality of users in a message thread, addresses the particular preferences of a user or users so as to improve the individual experience of the particular users as compared to performing recommendations uniformly across the user base of a consumer-to-business communication system  100 . 
     The interaction processing component  760  determines the bot relevancy for the two or more suggested bots to determine one or more filtered bots. Determining bot relevancy may be based on one or more signals, such as, without limitation, user profile information, user behavior information, user location information, user messaging context information, and user bot history information. The client communication component  740  may retrieve user information for use in analyzing the signals and provide the user information as part of the user information exchange  730 . 
     User profile information may include a variety of different types of information. User profile information may include demographic information. User profile information may include relationship information. User profile information may include education and/or occupational information. User profile information may include preference information, such as user-generated information indicating a user&#39;s favorite media, services, or other preferences. As such, the user profile information may include user service preference information in the user profile for a user. 
     Bots may be empowered to provide bot ranking information relevant to ranking the bots to the consumer-to-business communication system  100  to aid the consumer-to-business communication system  100  in ranking the bots. A bot may be provided with information describing a user service prompt and/or the one or more users prompting an offer of one or more bots. The bot is allowed to analyze this information and provide bot ranking information indicating its own analysis of whether it is appropriate for responding to the user service prompt and/or providing service to the one or more users. The bot may be encouraged to provide an honest and accurate assessment by penalizing bots that provide bot ranking information indicating that they should be highly ranked, but who are then poorly received by users. In general, the bot may be encouraged to provide an honest and accurate assessment by rewarding bots that provide bot ranking information that positively corresponds to user reception of the bot and by punishing bots that provide bot ranking information that poorly corresponds to user reception of the bot. User reception of the bot may comprise one or more measures of user response to a suggested bot, such as, without limitation, a bot being selected for use, a user using a bot to receive a service, and user satisfaction with a service received from a bot or some other element of a bot experience. 
     The interaction processing component  760  queries the two or more filtered bots for bot ranking information and ranks the two or more filtered bots based on the bot ranking information. The ranking of the filtered bots may determine which of the filtered bots are displayed for one or more users and/or the order in which the one or more filtered bots are displayed for the one or more users. The ranking bot information may contribute to the determination of a ranking order for the filtered bots. A highest-ranked groups of filtered bots may be provided to one or more client devices for display and ordered for display based on the ranking order of the provided filtered bots. The bot ranking information may comprise at least a portion of the bot information exchange  795 . The bot ranking information may comprise a numerical score generated by the bots, with the numerical score contributing to a ranking number for each bot through a mathematical combination of multiple factors including the numerical score. 
     In some cases, a bot may be provided with user information for a user to aid it in generating the bot ranking information. Querying the two or more filtered bots for the bot ranking information may comprise providing user information for a user account, where the user service prompt is associated with the user account for the bot-service system. The user information may comprise user profile information, such as may include demographic information and user-interest information. The user information may comprise user-service-preference information. The user information may include location information, which may be particularly of use for bots that relate to service that include a physical component, such as for food delivery or transportation. 
     User information is kept secure by the consumer-to-business communication system  100  and, as such, permission from a user to share user information may be required before the information is shared. As such, the interaction processing component  760  may determine a user-information share setting for a bot of the two or more filtered bots and request a user-information share permission from the user account based on the user-information share setting and the determining of the bot as a filtered bot. A user-information share permission is a permission for user information associated the user account to be shared with third parties. Such a permission may be required before information is shared with third parties. In some embodiments, permission to share information with third parties may be asked and received for all bots using the consumer-to-business communication system  100 , such that permission is granted to share certain information in general when determining suggested bots. Alternatively, in some embodiments, permission to share information with third parties may be asked and received for a specific bot, such that permission to share user information is requested from the user for that specific bot and a received permission is only for that specific bot. As such, in these embodiments, a user may be asked for further permission to share information with other bots. 
     In one case, the filtered bots may include an account-based bot. An account-based bot is a bot where use of the bot to receive a service uses a user account in addition to the user account used for the consumer-to-business communication system  100 . For example, the user may have a messaging account for a messaging system  140  and then a distinct user account for use with a ride-sharing bot. While these accounts may be linked to each other to ease use of the service with the consumer-to-business communication system  100 , they represent distinct registrations of the user with distinct systems. In this case, the user information provided to the account-based bot may comprise account information for the account-based bot, such as account information for a service associated with the account-based bot. For example, a ride-sharing bot associated with a ride-sharing service, such as may also be represented by a ride-sharing application on a user client device. 
     The bot-service system may be operative to chain user interactions with agents such that one interaction with an agent produces additional suggestions that can lead into an additional agent, with this pattern potentially continuing indefinitely. An agent may comprise any entity operative to interact with a message thread in service of the participants in the message thread. Agents may comprise one or more of one or more messaging bots, one or more multiple-user applications, one or more messaging client tools, and one or more social-networking tools. A messaging client tool may comprise a messaging client feature operative to provide a service to a message thread based on user input and producing a result for the message thread. A social-networking tool may comprise a messaging client feature operative to provide a service based on social-networking information and/or generating social-networking information for a message thread. 
     An agent may comprise a multiple-user poll tool. A multiple-user poll tool may provide a pool on multiple client devices that collects a selection from the client devices and provides a group selection based on the individual selections from the client devices in the message thread. A multiple-user poll comprises a plurality of options. In some cases, the options of a multiple-user poll tool may be configured by a primary user, with the primary user and one or more secondary users—collectively comprising the participants in a message thread—then voting on those options, with the result of the multiple-user pool comprising the majority or plurality selection from among the options. In some embodiments, the consumer-to-business communication system  100  may configure the one or more options automatically. The automatic configuration of options may be based on one or both of messaging interaction information and bot information from a messaging bot. Bot information from a messaging bot may comprise messaging bot configuration options. Messaging bot configuration options may comprise options available for configuring a messaging bot for the configuration of a service to be provided by the messaging bot. 
     Chaining user interactions with agents may be based on the agents subscribing to particular events. Events include, but are not limited to, a result being produced from an interaction with a message thread. The interaction processing component  760  may receive a plurality of agent-event subscriptions for a plurality of agents at a bot-service system as part of a bot information exchange  795 . An agent is subscribed to one or more events as part of the configuration of the agent for use with the consumer-to-business communication system  100 . For instance, a messaging bot may be subscribed to various events as part of a developer configuration of the messaging bot. 
     The interaction processing component  760  detects an event associated with a user account. This user account associated with a user client device. The interaction processing component  760  matches the event against the plurality of agent-event subscriptions to determine one or more event-response agents and identifies the one or more event-response agents to the user client device in response to detecting the event. The event-response agents may be identified to the user client device as a plurality of suggested agents available for selection by the user. 
     An event may comprise one or more of a user service prompt, a social-information update for the user account, and a user context change for the user account. A user service prompt may comprise a detected interest in engaging in an agent-based service in an interaction between two or more users. A social-information update may comprise, without limitation, one of a relationship status change and a friend addition. A user context change may comprise, without limitation, a user location change. An event may comprise a bot interaction result. A user location change may correspond to a arriving on a particular city block, arriving in a particular city, or any other user location change. 
     The event may be detected based on a portion of an interaction between two or more users. For instance, the consumer-to-business communication system  100  may perform a multiple-user poll tool, receive a multiple-user poll result from the multiple-user poll toll, and generate a subsequent event for the interaction based on the multiple-user poll result. A subsequent event may be matched against the plurality of agent-event subscriptions to determine one or more additional event-response agents. These additional event-response agents may then be identified to the user client device in response to detecting the subsequent event. The event may be detected according to event information. The event information may be received via a messaging client on the user client device, with the one or more event-response agents identified to the messaging client on the user client device. Event information may comprise, for example, planned attendance at a particular location for a particular event. 
     An NLP component  560  may comprise a natural-language machine-learning component, such that the NLP component  560  is operative to improve its performance using machine-learning techniques. The interaction processing component  760  may therefore teach the natural-language machine-learning component based on a bot interaction history for the bot-service system. 
     In some embodiments, a taxonomy may be used for an initial period of a bot-service system and then replaced with a machine-learning based matching between bot capabilities and service prompts. A taxonomy may comprise a human-generated taxonomy that represents bot capabilities according to a defined taxonomy, with the interaction processing component  760  matching user prompts against the bot capabilities based on the defined taxonomy using techniques for defined taxonomies. The interaction processing component  760  may perform a plurality of taxonomy-based bot selections for the bot-service system to generate at least a portion of the bot interaction history. 
     The consumer-to-business communication system  100  may iteratively improve its performance by using machine learning based on its ongoing experience with suggestions bots to users. The bot application interface component  780  receives a plurality of bot capability catalogs for a plurality of bots at the bot-service system. Each of the plurality of bot capability catalogs expresses bot capability in natural language for an associated bot. The client communication component  740  receives a plurality of user service prompts from a plurality of user client devices, the plurality of user service prompts expressed in natural language. The interaction processing component  760  determines selected bots of the plurality of bots for each of the plurality of user prompts by matching the plurality of user service prompts against the plurality of bot capability catalogs using a bot capability table  710  generated by a natural-language machine-learning component. 
     The client communication component  740  provides the selected bots to the plurality of user client device in response to receiving the plurality of user service prompts. The interaction processing component  760  records a bot interaction history based on user interactions with the selected bots and then updates the natural-language machine-learning component based on the bot interaction history. The interaction processing component  760  gathers signals related to the performance of the bots based on the bot interaction history. 
     The interaction processing component  760  may update the natural-language machine-learning component based on optimizing for bot completion rate. Bot completion rate may correspond to the rate at which users complete an interaction with a bot. An interaction with a bot is completed where the interaction produces a result for the user. Optimizing for bot completion rate may be based on user bot dismissal rates. Optimizing for bot completion rate may be based on maintaining a user bot dismissal rate below a defined bot dismissal threshold. Optimizing for bot completion rate may be based on user-bot-history signals. User-bot-history signals indicate information about the interactions between users and bots. Where the bot capability table represents the plurality of bot capability catalogs as a plurality of bot capability vectors, the interaction processing component  760  may update the natural-language machine-learning component to modify the mapping between the plurality of bot capability catalogs and the plurality of bot capability vectors. 
     In some embodiments, the interaction processing component  760  may update the natural-language machine-learning component based on increasing bot information sharing. Bots which produce a result but do not share information about the result using formal information-reporting signals to the bot-service system may be penalized by having their rank in the suggested bots lowered. Similar penalization may be performed where a bot receives user information in the configuration of a service but does not provide that user information to the bot-service system. In contrast, bots may be rewarded with higher ranking where they provide information to the bot-service system, such as user information about a user determined during the configuration of a service.

These and other input devices are often connected to the processing unit  1104  through an input device interface  1142  that is coupled to the system bus  1108 , but can be connected by other interfaces such as a parallel port, IEEE 1394 serial port, a game port, a USB port, an IR interface, and so forth. 
     A monitor  1144  or other type of display device is also connected to the system bus  1108  via an interface, such as a video adaptor  1146 . The monitor  1144  may be internal or external to the computer  1102 . In addition to the monitor  1144 , a computer typically includes other peripheral output devices, such as speakers, printers, and so forth. 
     The computer  1102  may operate in a networked environment using logical connections via wire and/or wireless communications to one or more remote computers, such as a remote computer  1148 . The remote computer  1148  can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer  1102 , although, for purposes of brevity, only a memory/storage device  1150  is illustrated.

     A procedure is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. These operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic or optical signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It proves convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be noted, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to those quantities. 
     Further, the manipulations performed are often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. No such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein which form part of one or more embodiments. Rather, the operations are machine operations. Useful machines for performing operations of various embodiments include general purpose digital computers or similar devices. 
     Various embodiments also relate to apparatus or systems for performing these operations. This apparatus may be specially constructed for the required purpose or it may comprise a general purpose computer as selectively activated or reconfigured by a computer program stored in the computer. The procedures presented herein are not inherently related to a particular computer or other apparatus. Various general purpose machines may be used with programs written in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the required method steps. The required structure for a variety of these machines will appear from the description given.
