Description:
CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    The present application claims the benefits, under 35 U.S.C.§119(e), of U.S. Provisional Application Ser. No. 61/994,625 filed May 16, 2014 entitled “Method and System for Generating Business Referrals from Chat Discussion Groups” which is incorporated herein by this reference. 
     
    
     TECHNICAL FIELD 
       [0002]    The invention relates to methods of using the Internet to promote goods and services and connect merchants with potential purchasers. More particularly the invention relates to methods of using software agents to assist chat groups in obtaining suitable sources of goods and services. 
       BACKGROUND 
       [0003]    Various methods have been developed for directing online shoppers to merchant web sites of interest and rewarding the referring party for the referral. For example U.S. Pat. No. 6,029,141 to Amazon.com, Inc. discloses a method of Internet-based referral wherein associates market products of a merchant on their websites which customers may then purchase through a referral link on the associate website which takes the customer to the merchant website. If the customer purchases the product then the associate is paid a referral fee. 
         [0004]    Similarly searches on map sites such as Google maps will provide recommendations to the searching party as to a restaurant, hotel etc. in the vicinity of the location searched. A large proportion of communications by smartphone now consist of smartphone instant messaging or SMS messaging. To date however businesses have not taken advantage of group discussions such as chat messaging groups where such groups are searching for products or services on a group basis, nor have they taken advantage of contextual information which can affect the current inclination of such groups to purchase goods or services. 
         [0005]    Google has created an online knowledge base called Knowledge Graph which uses semantically organized information to enhance its search results. Interest graphs are also used as online representations of a particular individual&#39;s specific interests. 
         [0006]    A “software agent” is a computer program that acts independently to perform tasks for its principal, whether a person or another computer program. 
         [0007]    Software agents have been used for many years in such roles as shopping or buyer agents, monitoring and surveillance agents, data mining agents and communication agents. Software agents add to the user&#39;s capability to obtain useful information. 
         [0008]    Programmatic advertising is a term for the buying of impressions on smartphone apps or websites, known as “programmatic direct”. Buying can be triggered automatically through a predefined set of conditions in much the same way that stock trading is done. Since smartphones generate contextual data about their users, it would be desirable to use such contextual awareness and programmatic buying of ads to allow companies to target users on mobile apps and websites for advertising. 
         [0009]    The foregoing examples of the related art and limitations related thereto are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those of skill in the art upon a reading of the specification and a study of the drawings. 
       SUMMARY 
       [0010]    The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope. In various embodiments, one or more of the above-described problems have been reduced or eliminated, while other embodiments are directed to other improvements. 
         [0011]    An embodiment provides a computer-implemented method of using the Internet to promote goods and services and connect merchants with potential purchasers in chat groups who wish to obtain suitable sources of goods and services, wherein a plurality of users each have a computer device provided with chat application software and software for accessing and interactively communicating via a computer network with a server provided with a search engine for searching the Internet comprising:
   a) said users initiating a chat conversation among a group of users;   b) one of said users invoking a search application for utilizing said search engine;   c) said one of said users conducting a search of the Internet for products or services;   d) said one of said users reviewing the results of said search of the Internet for products or services and selecting a product or service located by said search;   e) said one of said users injecting said selected search result into said chat conversation;   f) said one of said users or others of said users ordering said selected product or service.   
 
         [0018]    A further embodiment provides a consumer-oriented software agent accessed from any mobile device, tablet, smart device, laptop or desktop computer. The agent curates an understanding of each user&#39;s past, current and possible future states and needs in the form of a user graph which creates and tracks the constantly evolving and changing User state. To do this a novel form of notation can be used for communication between User and Agent, such as a Simple Knowledge Graph Notation. Once the Agent has built a User Graph, the agent can assist the user in locating useful information and predicting the user&#39;s future states and needs. The agent then can also assist chat groups in obtaining suitable sources of goods and services by combining the user graphs of the users in a chat group into a group graph. 
         [0019]    In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the drawings and by study of the following detailed descriptions.

     DESCRIPTION 
       [0033]    Throughout the following description specific details are set forth in order to provide a more thorough understanding to persons skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. Accordingly, the description and drawings are to be regarded in an illustrative, rather than a restrictive, sense. 
         [0034]    For purposes of this application the following definitions apply: 
         [0035]    A “User Graph” is a real time dynamic graph formed from contextual data relating to a specific user which is built from data collected from User chats, searches, existing interest graphs such as the User&#39;s Facebook interest graph, smartphone apps, web browsing and other available User behavioral data in which the nodes consist of objects, people, places, things, concepts etc. and an edge defines a relation between the vertices connected by the edge. It can be visually represented as a graph consisting of nodes and edges. It can consist of a number of subgraphs. 
         [0036]    A “User State Graph” is the state of a User Graph at a given point in time. 
         [0037]    A “Group Graph” is a real time dynamic graph formed from the User Graphs relating to a number of specific users who form a chat group. 
         [0038]    A “Group State Graph” is the state of a Group Graph at a given point in time. 
         [0039]    “Agent” is a software agent which maintains the User and Group Graphs. 
         [0040]    With reference to  FIG. 1   a,  the method of the invention is carried out by users  10  via a plurality of user computer terminals, whether desktop, tablet, laptop, smart phone, other mobile device or the like, and provided with application software to access Agent server  22  via Agent web server  12  via the Internet  14  and a social network hosting server  24 . A vendor advertising agent server  16  also accesses Agent web server  12  via the Internet  14 . 
         [0041]    In a first basic embodiment of the invention illustrated in  FIG. 1 b   - 1   g,  a group of users  10  participate in a chat conversation over smartphones  10  provided with a chat application such as Facebook Messenger, and a search agent application according to the invention. Fig. lb illustrates a screen shot from the smartphone of a participant in a chat session among the group “Calgary Troublemakers” on Facebook Messenger. The control panel at the bottom of the screen includes an extra icon, shown as a magnifying glass  11 , which is a search button. During the chat conversation, a user  10  may touch the search button  11  to send a request to the operating system, which invokes the search agent (“Max”) screen shown in  FIG. 1   c.  The user can then enter search terms in box  13 . The device&#39;s GPS may automatically enter a geographic limiter for the search in box  15 , or the user can enter a different geographic location. A search engine (e.g. Google or the system&#39;s own search engine) then carries out a web search based on the key words and returns the search results as shown in Fig. lc, preferably filtered into different categories, one of the examples in this case being “Products”.  FIG. 1 d    illustrates a screen shot when the user selects the “Product” category to review the search hits. Each search hit is displayed as a card or tile  17 . The source of the search hit is shown by the logo at  19 . By tapping the card  17  on the smartphone screen, the screen shown in  FIG. 1 e    is invoked. At the screen shown in  FIG. 1   e,  the user can compose a message to insert the selected search result into the chat group, or directly order the product. A comment about the selected product can be entered in box  21 . Selecting the order button at  25  takes the user to the source of the search hit to order the product. 
         [0042]    Still with reference to  FIG. 1   e,  by selecting the “Send” button  27  the user can inject the selected product card into the chat group or send it to other recipients. Tapping the “Send” button  27  takes the user to the screen shown in Fig. if where the user can select the recipients to be sent the product card. Tapping the arrow at  29  will inject the product card and comment as shown in  FIG. 1 e    back into the chat conversation in  FIG. 1 b    from which the search function was invoked, or the user can elect to send the card as a separate message to each selected recipient by tapping the “Send Separately” button  31 .  FIG. 1 g    illustrates the product card having been injected into the chat group. Any user can then re-distribute the card or order the product displayed by tapping the card  33 , which takes the user to the screen shown in  FIG. 1   e,  from which the user can order the product or re-send the card. The display on each user&#39;s screen includes a “Reply” button  35  which when tapped will take the user to the “Max” search screen shown in  FIG. 1 c    to review the other search results or conduct a new search. 
         [0043]    While the foregoing method illustrates the search for a product, the same method also functions for searching for services, such as a restaurant. In the case of a restaurant service, selecting the “Order” button  25  once a search result card has been selected will take the user to a reservation page for the selected restaurant (such as “Open Table”). 
         [0044]    Thus the method allows the participant in a chat group to use a search agent “Max” to locate a product or service, during the course of a conversation, and display a selected product or service to the group for ordering. Thus a process of chatting, searching for a product/service, selecting the product/service from the search results and sharing the selected product/service into the chat group is provided. Until the Agent has a complete enough User Graph to automatically return requested content directly into the chat itself, this more manual system of search, select and share must be used to help build the User Graph and train the Agent. The system is monetized by obtaining a payment from the source of the product or service when the product/service is ordered and paid for from the vendor of the product/ service. In carrying out the foregoing activity, the User&#39;s searches, selections and sharing actions further build out the User Graph, as described in detail below, every time a search is performed. 
       User Interest Graph Structure, Building &amp; Maintaining 
       [0045]    In a more sophisticated embodiment, a number of the Users  10  on smart phones  10  provided with the necessary app register with Agent  22  over web site  12  and provide certain common basic information about the User such as age, sex, marital status, residential address, education etc. The User enters an agreement with the Agent to address privacy and other issues to permit the Agent to collect information from the User concerning the User&#39;s location, searches and communications. 
         [0046]    The Agent generates the User Graph for the registered user, starting with the basic information provided on registration and collected over time by the Agent which processes such information to curate, learn, query and predict things of use and interest to the User. Each User Graph itself may comprise many subgraphs: event, search, social, interest, behavioral, biological, location, etc. Each of these subgraphs may have its own specific set of applied properties and ontologies. The User Graph can be built and curated by the Agent through automated collection of in-context data and by direct entry from the User themselves to directly curate parts of their own User Graph or Subgraphs. An example of automated collection is the User&#39;s Interest Graph where in Facebook the User can like something. Another example would be to use the in-chat search app described above to map the User&#39;s search, selection and sharing choices. The Agent collects and processes the information to create and track the state of each of these subgraphs and may employ sub-agents or external services to format and update these subgraphs. This approach of subgraphing the User Graph provides flexibility in curating current in-use subgraph data collections with the ability to add new subgraph types defined by new ontologies or processes without disruption to existing in-use subgraphs. For example, a User “Search Subgraph” that contains the User&#39;s solo or in-chat searchs, selections and what they then shared, as described above, can be created and updated by the Agent. 
         [0047]    Preferably the User&#39;s relationship with the Agent starts before a chat with others even begins, using features like search or a feed app described below and others where the User and the Agent are working together initially to build out the fully curated User Graph. The Agent interacts and learns from the User and fills out subgraphs to the point of curation. A trust relationship is developed between the User and the Agent. Helping the user work with the Agent to build out the other User Graph subgraphs like the Event subgraph (planning/calendar), plugging in wearables data (heart rate, blood pressure, blood chemistry etc) into the Biological subgraph, etc. 
         [0048]    By using a particular notation, described herein as Simple Knowledge Graph Notation (SKGN) to communicate data to the Agent, the User can help build higher density knowledge faster with less required computational resources. From the outset, the User may ‘chat’ with the Agent and tell them things and/or the Agent presents them with various User Interfaces (i.e. interest graph “Like”, “dislike”, “Loves”, “hates”, “Scary”, “Agrees” etc). This helps accelerate the building of the User Graph which in turn allows the Agent to do things and find things of high value to the User. Initially the Agent may start as a slightly more useful search function for the User (than other search engines), much like current search engines but as the User and Agent interact by the filling out or collection of information to fill out the User Graph, there will be a curve of convenience and reliance wherein the User begins to interact more intimately with the Agent and there is an exponentially growing level of detail in the User Graph, which then levels off when the bulk of the user subgraphs are filled out and the rate of density increase resembles a true machine prediction and curation curve. This is illustrated in  FIG. 2 . 
         [0049]    Currently other search agents play a passive role, analyzing the User&#39;s actions and behavior behind the scenes and present the user with suggestions based on probability-based lower density knowledge sets. By using SKGN the User can direct the Agent to higher density knowledge sets while utilizing less computational power, all producing much more accurate suggestions for the User. 
       User Graph Knowledge Density and its Value 
       [0050]    High density knowledge sets in the User Graph are valuable because they represent richer paths through knowledge space and thus capture more accurate user context, user state and subgraph state information. 
         [0051]    As an example, a low density knowledge set would look like: (UserA)—[LIKES]—&gt;(Beer) 
         [0052]    A high density knowledge set would look like: 
         [0053]    (UserA)—[LIKES]—&gt;(Beer)—[TYPE]—&gt;(Lager)—[BRANDED]—&gt;(BeerWorks Lager)—[PACKAGED]—&gt;(Stubby Bottles)—[STATE]—&gt;(chilled) 
         [0054]    It is difficult to build high density knowledge sets using passive methods as is currently done and costs more in processing time and analysis to infer the same level of density, which may still suffer from a probability of failure. If the User formats the foregoing knowledge set using one or more SKNG operator, the Agent can become much more accurate i.e. #beer&gt;lager&gt;chilled or #beerlagerchilled—the Agent will be able to leverage a higher density knowledge set to make more desirable suggestion sets. This leverages the ability for the user to directly supply the agent with personal explicit knowledge to use in the subgraph as contrasted to the agent filling the subgraph with inferred probabilistic knowledge (i.e. bayesian). 
         [0055]    Unlike other existing agents there are two coupled learning curves in action: One for the Agent about the User and One for the User about the Agent. The Users themselves collect data/knowledge to build User Graph Knowledge Density (and for the Group State Graph a discussed below) by the User being asked questions and taught how to format Knowledge information and questions for the Agent (for example using SKGN). Existing systems scan through users&#39; data, for example emails and searches. Here active collection is done in parallel with background Natural Language Processing and Inference. Here not only will the Agent receive communications from the User to build the User Graph but also the User will receive communications from the Agent, such as communications in Simple Knowledge Graph Notation (SKGN) suggesting paths of possible interest. The Users learn how to better communicate with the Agent using SKGN. Hence there is a two-way dialogue. 
       Three Distinct Phases in the User-Agent Relationship Curve 
       [0056]    a) Phase I: With specific reference to  FIG. 2 , in Phase I the User and Agent are just getting to know each other. User Graph (and subgraph) knowledge density is low. The Value to the user is similar to a Google search with somewhat more usefulness because of Agent&#39;s basic knowledge about the User&#39;s gender or raw data like the User&#39;s geolocation. Typically in this phase, there is reliance on Natural Language Processing (NLP) and Inference to build the User Graph with probabilistic guesses. As the user selects specific suggestion tiles, those knowledge sets are added to the relevant User subgraph, the subsequent Group State Graph (GSG) and to the Conversation subgraph. 
         [0057]    b) Phase II: As the User begins to use more direct methods to actively direct the Agent to specific tasks, the Agent is able to build accurate, high density knowledge in the User Graph. This gives the Agent better data for machine learning and conversely, it is able to ask the User more relevant questions and present more relevant suggestion tiles. This methodology of using SKGN in conjunction with other methods has an advantage over existing approaches and creates an exponentially-sloped curve simply because the User and Agent know how to talk to each other and more efficiently transfer information between them. The SKGN notational efficiency provides operational advantage over existing agent services. 
         [0058]    c) Phase III. Like any relationship, the amount of new information and knowledge set sharing will taper off and the emphasis will be on the maintenance and curation of the User Graph of knowledge sets. Once this part of the curve has been reached, the ability for the Agent to predict accurately what the User will want will be greater than existing approaches because the Agent will have access to deeper value high density knowledge sets and the ability to curate them directly via the User. This power will also be passed on to the GSG where the Agent(s) will be able to leverage group usage of SKGN to deliver more accurate suggestion tiles. 
       User Case: The Feed App 
       [0059]    As additional tools for assembling a deeper User Graph, a News Feed 
         [0060]    App may be provided by allowing the Agent to chat directly with the user (and other UI components). In this context, there are no others involved with the User and the Agent and the Agent is engaging the three phases with the user to build the User Graph and to find interesting things on the internet to build a continuous feed of items for the user to consume, much like a Smart RSS feed. The User gives the Agent permission to scan and pull information directly from the Facebook and Twitter feeds as well as other sources like RSS news feeds. The User also informs the Agent of topics and contexts of interest to build knowledge sets to help the Agent find and filter links to interesting content. 
         [0061]    For example, 
         [0062]    (UserA)—[LIKES]—&gt;(Beer)—[TYPE]—&gt;(Lager)—[BRANDED]—&gt;(BeerWorks Lager)—[PACKAGED]—&gt;(Stubby Bottles)—[STATE]—&gt;(chilled) 
         [0063]    + 
         [0064]    Beerworkslager&gt;events&gt;beergarden 
         [0065]    Could produce a contextual Topic filter for the Feed like: 
         [0066]    (UserA)—[LIKES]—&gt;(Beer)—[TYPE]—&gt;(Lager)—[BRANDED]—&gt;(BeerWorks Lager)—[EVENT]—&gt;(BeerGarden)—[STATE]—&gt;(chilled) 
         [0067]    might lead to a link to relevant events within a geofence where BeerWorks Lager is being served chilled, possibly in stubby bottles. 
         [0068]    The user may take a resulting feed item like this and use it to INITIATE a chat with others. 
         [0069]    For example, a Feed item has a (start chat) button on it which allows the user to select a few chat participants and initiates a chat with the feed item at the top. 
         [0070]    [Feed Item A]—&gt;‘beerWorks Beer Garden Event’ (link) 
         [0071]    [Feed Item A]—&gt;Select Item Chat 
         [0072]    [Contacts List]—&gt;Select Group members 
         [0073]    [Initiate and Invite to chat] 
         [0074]    In Chat; 
         [0075]    [link to Beer Garden Event] 
         [0076]    [Hey guys! I found a Beer Garden gig this weekend where they are serving our fav BeerWorks Lager!] 
         [0077]    In this way the Agent technology is involved from the outset, even being used to seed the beginning of any conversation. 
         [0078]    To be of practical usage, the User Graph with all subgraphs may be ‘quantized’ into a number of “User State Graphs” which are a snapshot of the User Graph at a time (t) as illustrated in  FIG. 3 . For example that answers simple questions like “What did the user like last Wednesday?”, “What mood is the user in at the moment?”, “What do we think the user will want to eat next Friday at lunch?” The visual representation of the User State Graphs can be thought of as a slice across the time axis revealing the User Graph and its subgraphs as a fixed entity-edge graph diagram. 
       Leveraging the User Graph 
       [0079]    This quantization of state is necessary for the Agent to be able to perform discrete analysis and processing of the User Graph or to hand off an anonymized User State Graph to other Agents for processing, conversation and transaction graph construction. Examples of User State Graphs for Users A, B and C are shown in  FIG. 8 . User State Graph processing can be done by the Agent, sub-agents, affiliated Agents or arms length Agents or by a number of technologies to analyze it and perform valuable services such as (but not limited to) inferring the User&#39;s likelihood of hunger, choosing and suggesting an appropriate meal or finding a meal purchase discount in advance and lining that up with a mobile payment provider. 
         [0080]    To perform its analysis, the Agent may use, but is not limited to, open ontologies/taxonomies, folksonomies or private thesauri versions. The Agent may use (but is not limited to) SKOS, OWL or OWL2 open source Inference engines or private black box inference engines. The Agent may use (but is not limited to) statistical analysis to determine relevance, deep learning techniques between successive User State Graphs or Natural Language Processing to augment User State Graph processing.  FIG. 4  illustrates User A&#39;s State Graphs at two times t 1  and t 2 . Between those times User A has eaten a spicy meal. The Agent Actions on the User Graph are shown, The Agent updates the User Graph at t 2  based on the changes which occurred after t 1 . The Agent may then infer that the User needs water or medical assistance and presents suggestions to the User for action. Finally the Agent updates the User Graph at time t 3 . 
       Group Chat Assembly 
       [0081]    With reference to the flow chart in  FIG. 5 , this illustrates the process for server  22  (or other server) to assemble a group chat among Users, even on different chat platforms. As the first step ( 1 ) Contacts: inside the mobile native or web app, User A navigates to his list of contacts, shown in  FIG. 6 . This list is the aggregation of contacts pulled from the smart phone as well as various social networks. The entire list might therefore contain a number of contacts for the same person. 
         [0082]    At step  2  of  FIG. 5 , Contact Select, User A selects  1  or more contacts from the list that they want to start communications with. These contacts could be from anywhere in the contact list and do not have to be from the same chat provider. At step  3 , Invite—User A now posts a message into the newly created chat room. This message is now sent to the server to allow it to deal with routing and user creation. At step  4 , Transport—information is sent to the server for processing. 
         [0083]    At step  5  Routing—Server  22  uses a routing table to look up which providers User B and C are on. Once the server knows how to handle the message it forwards the message on to be sent out by the message handlers. At step  6 , Link—the server looks to construct a unique url that will allow the user A or B a temporary login to the chat. At step  7 , User Create—server  22  will find or create a “Pseudo” user account that will be used in the authentication of the link that is given out. The link is then sent using the proper provider to the users. 
         [0084]    Those chat group members who are pseudo-users and do not register with the Agent will not have a password to the system and may not have full access to features in the system such as the ability to independently utilize the Agent outside of the chat group. The system assigns an account identifier for each pseudo-user referenced to the pseudo-user&#39;s email, Facebook, Twitter, Linked-In, Xbox (or any other current or future provider&#39;s) account through which the user was invited into the chat group. One individual therefore may have multiple pseudo-user accounts which eventually may become merged. The Agent will nonetheless build up the pseudo-user&#39;s User Graph as described below with whatever data is available as it would for a regular user. Eventually the pseudo-user may register as a regular user, either after participating in additional group chats, or when attempting to use the Agent. Various user interfaces can be provided at various intervals which will encourage the pseudo-user to register and log in. 
         [0085]    In step  8 , Acquisition—Users B and C click the link that was delivered in the chat as illustrated in  FIG. 7 , The link will launch the browser on that device and begin loading the web chat. In step  9  Authentication—the system uses the link to authenticate the “pseudo” user and move them into the web chat. Step  10  Unified Chat—Users are now in a unified chat view as illustrated in  FIG. 8  and are able to participate in the group chat and launch applications. 
         [0086]    With reference to  FIG. 9 , User State Mapping, the Agent  22  now combines the group chat members&#39; User State Graphs into a Group Graph. This can be done by complete Union, or statistical relevance (e.g. “We all like/love/crazy about Elvis”). This can also be done by simply working out the intersecting commonalities in all the User Graphs and maintaining those in the Group Graph as Group Common Interests (e.g. Everyone likes Lager and Spicy Food, Everyone dislikes Marching Band Music). In step  2  of  FIG. 10 , the Group State Graph (GSG) is derived from User State Graphs. This is used to process Group Chat activity and track it. 
         [0087]    The process for generating a Group State Graph from User State Graphs is shown in  FIG. 9 . As noted above, the Agent has the task of monitoring, curating, and mapping the User State Graphs to a Group State Graph continuously over time. The User Stage Graph may be restricted to relevant subgraphs and not all subgraph members. The objective with Group State Graph creation is not to lose any user information but also to map it into relevant subgraph information that can be acted on without referring to original user state graphs of group member users. Thus some computational inference and smart organization of the group state graph can be applied by the Agent to achieve this. 
         [0088]    Referring to the illustration of User State Graph Mapping in  FIG. 9 , the Agent preserves information but at the same time can map and reduce the Group State Graph. For example, as shown there is no need to preserve User C&#39;s normal blood sugar level, only the outlier user subgraph for Users A and B where the blood sugar levels are abnormal thus affecting a suggestion from the Agent. The same approach is shown in the example for a behavioral subgraph. Generally the Agent maps the union (overlap) of the User State Graphs but not necessarily the intersection or difference, though that may be useful for some situations. In the example shown, the Agent will normally want to keep the fact that User C dislikes spicy meals but in this particular state, User C will not be eating so that might be inferred as redundant information for this Group State Graph time slice, but would still be relevant to a later time slice. 
         [0089]    As the User State Graphs are updated, so is the Group State Graph which is made up of time slices of mapped User State Graphs. 
         [0090]    As an example of the Agent now utilizing the Conversation Graph which results from the conversation in  FIG. 8  and as described below to generate a suggestion, User A asks User B and User C if they have any plans and would like to get together in the early evening for a while. The Agent can infer that because User C is not eating, a more casual dinning selection might be more relevant as a more formal dinner would make User C feel uncomfortable. The Agent can infer that because User B is not attending but also has friends at the hockey game, perhaps the Agent should see if there are any tickets available for User B if they have no other plans that evening. 
       Chat Entities and Conversation Subgraphs 
       [0091]    In step ( 3 ) of  FIG. 10 , the Conversation Subgraph the building of which is shown in  FIG. 11 , is added to the Group State Graph. The Conversation Subgraph is the Agent&#39;s notes obtained from the group conversation to date. It is obtained by the Agent through the users&#39; use of a graph notation in the chat messages (for example a Simple Knowledge Graph Notation or SKGN) and the Agent&#39;s analysis of it. The Conversation Graph may or may not be maintained after a group ‘closes’. This may depend on whether or not group is ad hoc or is named/saved. A Conversation Graph for a chat session is constantly developing and added to as the conversation threads and branches. SKGN (or direct Agent involvement) sets a current focus state of the Conversation Graph so that incoming agent or vendor suggestions can be added to the conversation graph at the focus topics. “Focus topics are shown as bold circle/ovals in  FIG. 11 . 
         [0092]      FIG. 11  illustrates the Conversation Subgraph &amp; Agent Action Initiation. At the initiation of every chat, the Agent adds (if not already present, i.e. saved) a subgraph to the GSG called the Conversation Subgraph. The Conversation Subgraph is a mutual shared graph between all of the users and agents in the chat. Like any social network conversation, there is typically a starting topic, that participants comment on and over the course of time, the comments and conversation tend to branch into new topics related or relevant to the first topic. This bifurcation process is a natural part of human communication and is seen in most social network comments and instant messaging chats. 
         [0093]    Every Group Graph can have one or more conversation subgraphs representing different chats or conversations belonging to that group. At the beginning of every chat session, the agent chooses a pre-existing conversation subgraph or creates a new one for that Group Graph. Different conversation subgraphs can be accessible by some or all of the group members. Every Conversation Subgraph is composed of discrete chat entities, each of which represents a new entry into the Conversation Subgraph. A chat entity is a member of the graph database and can have other entities and properties associated with it. 
         [0094]    The chat entities are related to each other via a time sequence, as would be found in a normal chat sequence of entries. Different conversation subgraphs may be organized around users or topics and may not use a temporal sequence per se. All conversation subgraphs capture context in the way their chat entities are created and organized whether sequentially or topic-wise. 
         [0095]    Thus a given chat group may have multiple Conversation Subgraphs, with each Conversation Subgraph directed to a particular area/topic. The Agent can provide specialized application with customized user interfaces which are focused/trained on particular topics e.g. hockey, gardening etc. 
         [0096]    Like any social network conversation, there is typically a starting topic, that then participants comment on and over the course of time, the comments and conversation tend to branch into different topics related or relevant to the first topic. This bifurcation process is a natural part of human communication. 
         [0097]    The User can invoke the Agent to perform different tasks from searching for things or doing other actions based on the User&#39;s request. These are typically invoked by the use of SKGN, as shown in  FIG. 11 , by using the “#” and “&amp;” operators in conjunction with a keyword. 
         [0098]    In the example shown in  FIG. 11 , User C initiates an Agent search for tickets via “#tickets” to the event shared by User A. The Agent searches for tickets and then suggests ticket purchase options to User C to decide which to share with the rest of the group. In this case User A decides that purchasing the tickets from TicketVendor 3  is a good idea, they click the link presented in the Agent suggestion tile (shown as box “SUGGEST”) and are taken to TicketVendor 3 ′s website to complete the transaction for the ticket purchase. This may be by way of an Agent Tile Buy (Action) button which invokes the agent to open a window/tab to a vendor purchase screen (such as a ‘click here to purchase’ link below). 
         [0099]    The Ticket purchase details are sent to User A′s email and that ticket information link can be shared with the rest of the group as shown below. In addition to sharing the ticket information link, User A decides it would be a good idea to create a container (i.e. folder or bundle etc.) to attach the ticket info link to it as there will probably be more information that needs to be organized for the event such as maps, photos of the event etc. By using the “&amp;WeekendEvent” SKGN, the Agent creates a container (if one doesn&#39;t exist) called “WeekendEvent” and adds the Music Event Link, ticket purchase info link to it, including additional links for the redemption of three free beers at the event that were part of the ticket info web page. Note any of the other Users in the group chat can now add things to the group container. 
         [0100]    Later in the chat, User B decides to search for an Uber cab to convey the group to and from the Music Event. Again this is done using the SKGN #Uber hashtag and the append tag, “&amp;WeekendEvent”. At any point, any of the users can click the Agent presented ‘WeekendEvent’ link and see a display of all the information in the container. 
         [0101]    The primary goal of the conversation graph is to create a real time mappedgraph of the conversation so that the users and agents have a ‘scaffold’ to make decisions with. The conversation graph ‘grows’ with a the addition of focus topics (shown in bold) that are added to the conversation graph from the chat entities, typically in context to previous focus topics as shown in  FIG. 11 . Users can ‘vote’ on Agent suggestion tiles with semantic context such as literal vote, like, dislike, agree etc. These contexts are also recorded in the conversation graph as edge information between the focus topics and may allow the Agent to perform actions or add more focus topics to the conversation graph. Every incoming chat entity message can be analyzed by NLP, Inference or other method and the result can be a probabilistic addition of more focus topics to the growing conversation graph. 
         [0102]    By using SKGN, users can also directly grow the conversation graph, in this case one topic node at a time via usage of “#” As users react to each chat message or item introduced, they can add context to it and the agents can begin to infer possible actions to take or refine introduced suggestions. As Users ask agents to perform actions (such as search, buy, book, reserve, sell etc.), this creates an ‘n-branch decision path’ which is a subset of the conversation graph where decisions that lead to actions were made. In  FIG. 9 , these are represented by the heavier outlined objects and dotted lines. 
         [0103]    These decision paths are valuable in that they represent a ‘learned’ group behavior set completely in context and relevance to that user group. These may be stored in the Group&#39;s Behavior graph (so the next time the group wants to drink beer, the Agent has  3  previous choices to offer them) and also used in aggregate so that similar groups with similar context might also find them useful and actionable. 
         [0104]    With reference back to  FIG. 10 , step ( 4 ), Transaction Graph, the Agent builds and maintains the Transaction Graph from the Group State Graph. The Transaction Graph acts as an anonymized, simplified version of the GSG that contains essential details about the group and the groups desires. Most subgraphs may be removed and the GSG conversation subgraph may be normalized into strictly relevant purchase queries for Vendors and/or Vendor Agents to consume for Product/Service Entity suggestions. 
       ConversationTopics &amp; Simple Knowledge Graph Notation (SKGN); Agent Conversation Knowledge Collection &amp; Context/Relevance 
       [0105]    Looking at step ( 5 ) in  FIG. 10 , Group Chat User Interface—Focus Topics, this is the Primary interface for chat participants. It uses, for example the Simple Knowledge Graph Notation (SKGN) as described above to directly invoke the Agent. For example the users use the symbol “#” to designate a main topic of a chat and other symbols such as “&gt;” and “.” may be used to designate additional context for the main topic. The Agent may also self-invoke contextual data from the Users via Natural Language Processing or Inference derived queues as well, based on the Conversation Graph. The Agent curates the Conversation Graph as the group chat progresses and in turn also updates the GSG and Transaction Graphs. Users can set active focus topic nodes on the conversation graph by using the SKGN, and by returned suggestions from the Agent which get ‘attached’ to the conversation. The group chat can have more than one focus topic but even then may be in some relevant context (e.g. taxi, dinner &amp; movie). 
         [0000]    Agent Semantic Analysis &amp; Product/Service Matching; Agent Product/Service Selection from Context/Relevance; Agent Selection Tile Formatting and Presentation; User Selection Tile In-Chat Presentation 
         [0106]    Looking at step ( 6 ) in  FIG. 10 , Group Agents. On invoke, the Agent analyses the GSG and draws Product/Service Entity suggestions from Product and Service Knowledge Graph database (using for example the Google Knowledge Graph). These are displayed as ‘suggestion tiles’ in the Agent User Interface for the user to choose from. Once one or more tiles are selected, they are displayed in the Group Chat User Interface for the other chat members to consider. The User may also directly invoke a purchase/reservation directly from the Agent User Interface without informing other chat members. 
         [0107]    ( 7 ) &amp; ( 8 ) Vendor &amp; Vendor Agents. The Transaction Graph may also be made available to Vendors who have registered with the system and their Vendor Agents  24 . A Vendor who is interested in soliciting a group through their Transaction Graph can do that themselves ( 8 ) or through a more automated fashion via their own agent  24 . Vendor Agents can analyse the group&#39;s Transaction Graph and suggest products and services from the Vendor&#39;s database. 
         [0000]    Group Selection Tile Interaction &amp; Feedback; Group Selection Tile Execution &amp; Conversion (Call to Action); Call to Action Tile in-Chat Presentation 
         [0108]    Step ( 9 ) in  FIG. 10  illustrates the Agent User Interface—Suggestion Tile Display described above. The Agent User Interface displays all the suggestions for the current conversation state from the group&#39;s agent(s) or the Vendor and/or their agents. The User selects a suggestion and this gets added to the Conversation Graph focus node. Unselected suggestions can also be added to the focus node in different contexts. A User can also directly engage a transaction with the suggested product or service without Group participation. A User can save any or all members of the suggestion set for future recall and/or engagement. 
         [0109]    ( 10 ) Group Chat UI—Product Entity Selection. The User selections in step  9  are displayed in the Group Chat User Interface. Other group members can then offer comment, vote or otherwise participate in the decision to purchase the suggested product of service. 
         [0110]    ( 11 ) Purchase User Interface. The Purchase UI provides a transaction function by way of a payment system. Purchase UI may be hosted and operated by a selected product vendor such as Paypal or may be handed off to vendor site and the transaction completed outside of the Agent server  22 . Purchase is added to conversation graph as a purchased entity. 
         [0111]    ( 12 ) Fee Collection. A portion of the purchase transaction is credited to the Agent as representing the system operator. 
         [0112]    ( 13 ) Group Chat UI—Product Purchase Update. A Purchase Details (i.e. bundle) Tile is displayed in the Group Chat UI. The Purchase Tile is saveable/storable/retrievable by all group members. The Purchase Tile can include a receipt, map, scannable barcode, and the like. 
         [0113]    ( 14 ) Update Group Graph and GSG. At step  14  the Group Graph, GSG, Conversation and all other relevant graphs are updated. 
         [0114]    While those chat group members who are pseudo-users will not have a password to the system and may not have full access to features in the system such as the ability to independently utilize the Agent outside of the chat group, the Agent will have has generated a User Graph for each pseudo-user referenced to the pseudo-user&#39;s email, Facebook, Twitter, Linked-In, Xbox etc. account through which the user was invited into the chat group. One individual therefore may have multiple pseudo-user accounts which eventually can become merged. The Agent will build up the pseudo-user&#39;s User Graph with whatever data is available. Eventually the pseudo-user may register as a regular user, either after participating in additional group chats, or when attempting to use the Agent through user interfaces which may be provided at various intervals to encourage the pseudo-user to register and log in. There will further be an incentive for the pseudo-user to register with the system given that the pseudo-user will likely experience some of the benefits that come with the knowledge acquisition which has been carried out by the Agent. 
         [0115]    While a number of exemplary aspects and embodiments have been discussed above, those of skill in the art will recognize certain modifications, permutations, additions and sub-combinations thereof. It is therefore intended that the following appended claims and claims hereafter introduced are interpreted to include all such modifications, permutations, additions and sub-combinations as are within their true scope.
