BRIEF SUMMARY
Systems, methods, apparatuses, and computer program products described herein facilitate determination of a message recipient. The systems, methods, apparatuses, and computer program products provided in accordance with example embodiments of the invention may provide several advantages to computing devices, network providers, and computing device users. Some example embodiments determine to which of a plurality of active messaging conversations a message to be sent is relevant. Some such example embodiments determine which active messaging conversation a message is relevant to based at least in part upon data from historical conversations. Accordingly, some example embodiments enable determination of an appropriate recipient of a message by determining the conversation to which the message is relevant and designating the message to be sent to a recipient that is a party participating in the determined conversation. In this regard, some example embodiments utilize word correlation, such as based on one or more relevant word-to-word translation pairs accumulated from past messaging conversations, to calculate a semantic relevance between a message and an active conversation to facilitate determination of a target message recipient.
Users may particularly benefit from some example embodiments because a user may be able to enter messages to be sent in one of a plurality of active conversations without having to switch among different conversation windows. In this regard, in some example embodiments, a user may enter a message to be sent without designating a recipient for the message and the recipient may be determined by determining the conversation from among the plurality of active conversations to which the message has the greatest degree of relevance. Users may therefore benefit by not having to enter key strokes, mouse clicks, and/or other user input required to switch between active conversation windows to enter a message in a particular conversation window. Users may further benefit because some example embodiments may reduce the potential of a message being sent to the wrong recipient due to a user error resulting in a message being entered into a wrong conversation window. Network providers may benefit because some example embodiments may reduce the amount of excess data transfer that may occur if a user sends a message to an unintended recipient and then has to resend the message to the intended recipient. Some example embodiments may be easily and flexibly integrated into existing messaging applications and thus may be flexibly and rapidly deployed to improve the messaging experience of users of a variety of messaging platforms.
In a first example embodiment, a method is provided, which comprises determining a message to be sent in one of a plurality of active messaging conversations. The method of this embodiment further comprises determining a conversation to which the message is relevant from among the active messaging conversations based at least in part on data from historical conversations. The method of this embodiment additionally comprises designating the message to be sent to at least one recipient, wherein the at least one recipient comprises a party participating in the determined conversation.
In another example embodiment, an apparatus is provided. The apparatus of this embodiment comprises at least one processor and at least one memory storing computer program code, wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to at least determine a message to be sent in one of a plurality of active messaging conversations. The at least one memory and stored computer program code are configured, with the at least one processor, to further cause the apparatus of this embodiment to determine a conversation to which the message is relevant from among the active messaging conversations based at least in part on data from historical conversations. The at least one memory and stored computer program code are configured, with the at least one processor, to additionally cause the apparatus of this embodiment to designate the message to be sent to at least one recipient, wherein the at least one recipient comprises a party participating in the determined conversation.
In another example embodiment, a computer program product is provided. The computer program product of this embodiment includes at least one computer-readable storage medium having computer-readable program instructions stored therein. The program instructions of this embodiment comprise program instructions configured to determine a message to be sent in one of a plurality of active messaging conversations. The program instructions of this embodiment further comprise program instructions configured to determine a conversation to which the message is relevant from among the active messaging conversations based at least in part on data from historical conversations. The program instructions of this embodiment also comprise program instructions configured to designate the message to be sent to at least one recipient, wherein the at least one recipient comprises a party participating in the determined conversation.
In another example embodiment, an apparatus is provided that comprises means for determining a message to be sent in one of a plurality of active messaging conversations. The apparatus of this embodiment further comprises means for determining a conversation to which the message is relevant from among the active messaging conversations based at least in part on data from historical conversations. The apparatus of this embodiment additionally comprises means for designating the message to be sent to at least one recipient, wherein the at least one recipient comprises a party participating in the determined conversation.

DETAILED DESCRIPTION
Some embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like reference numerals refer to like elements throughout. As used herein, the terms “data,” “content,” “information” and similar terms may be used interchangeably to refer to data capable of being transmitted, received and/or stored in accordance with embodiments of the present invention. Thus, use of any such terms should not be taken to limit the spirit and scope of embodiments of the present invention. Further, where a computing device is described herein to receive data from another computing device, it will be appreciated that the data may be received directly from the another computing device or may be received indirectly via one or more intermediary computing devices, such as, for example, one or more servers, relays, routers, network access points, base stations, and/or the like.
Additionally, as used herein, the term ‘circuitry’ refers to (a) hardware-only circuit implementations (for example, implementations in analog circuitry and/or digital circuitry); (b) combinations of circuits and computer program product(s) comprising software and/or firmware instructions stored on one or more computer readable memories that work together to cause an apparatus to perform one or more functions described herein; and (c) circuits, such as, for example, a microprocessor(s) or a portion of a microprocessor(s), that require software or firmware for operation even if the software or firmware is not physically present. This definition of ‘circuitry’ applies to all uses of this term herein, including in any claims. As a further example, as used herein, the term ‘circuitry’ also includes an implementation comprising one or more processors and/or portion(s) thereof and accompanying software and/or firmware. As another example, the term ‘circuitry’ as used herein also includes, for example, a baseband integrated circuit or applications processor integrated circuit for a mobile phone or a similar integrated circuit in a server, a cellular network device, other network device, and/or other computing device.
Computing device users frequently use their computing devices to communicate with other users via messaging conversations. These messaging conversations may include any form of electronic messaging by which two or more parties may exchange text-based messages, graphics, data, and/or the like. Messaging conversations may be facilitated through use of any of a variety of electronic messaging types. One example of a messaging type that is widely used is instant messaging. Accordingly, instant messaging is used herein as an example to facilitate description of some example embodiments. It will be appreciated, however, that example embodiments may be applied to other messaging types used for engaging in messaging conversations, including, for example, electronic mail, text messaging, a conversation via multimedia messaging service (MMS) messaging, a conversation via short message service (SMS) messaging, twitter feed, microblog, internet relay chat, online chat, chat rooms, message board threads, community conversations having more than two parties, and/or the like. Further, it will be appreciated that messaging conversations are not strictly limited to text-based messaging. In this regard, a messaging conversation may comprise exchange of text content, graphic content, multimedia content, some combination thereof, or the like between users engaged in a messaging conversation. Thus, where instant messaging is referred to herein it is merely by way of example and not by way of limitation to a particular messaging type.
When talking with several people simultaneously via instant messaging, a user often is required to maintain multiple two-party conversation windows (for example, a conversation window for each person with which the user is engaged in a conversation), and switch among them during the messaging conversations. This arrangement may not be convenient to users in practice. Users may be inconvenienced by having to provide user input to switch between windows when engaged in the messaging conversation. Further, users often mistakenly type a message intended for a recipient participating in a first conversation in a conversation window for a second conversation.
Accordingly, some example embodiments may improve user experience when engaging in multiple messaging conversations by facilitating determination of a message recipient. Referring now to FIG. 1, FIG. 1 illustrates a block diagram of a system 100 for facilitating determination of a message recipient according to an example embodiment. It will be appreciated that the system 100 as well as the illustrations in other figures are each provided as an example of one embodiment of the invention and should not be construed to narrow the scope or spirit of the invention in any way. In this regard, the scope of the disclosure encompasses many potential embodiments in addition to those illustrated and described herein. As such, while FIG. 1 illustrates one example of a configuration of a system for facilitating determination of a message recipient, numerous other configurations may also be used to implement embodiments of the present invention.
In at least some embodiments, the system 100 includes a messaging apparatus 102 and a plurality of recipient apparatuses 104. The messaging apparatus 102 and recipient apparatuses 104 may be configured to engage in messaging conversations over the network 106. The network 106 may comprise a wireless network (for example, a cellular network, wireless local area network, wireless personal area network, wireless metropolitan area network, and/or the like), a wireline network, or some combination thereof, and in some embodiments comprises at least a portion of the Internet. As another example, the network 106 may comprise an ad hoc network formed between a messaging apparatus 102 and one or more recipient apparatuses 104. Such an ad hoc network may be formed, for example, through wireless communication between the messaging apparatus 102 and one or more recipient apparatuses 104.

In this regard, the messaging apparatus 102 may be embodied as any computing device configured to implement a messaging conversation application and provide a user interface allowing a user to enter messages for sending to a party participating in a messaging conversation, such as to a user of a recipient apparatus 104.
As another example, the messaging apparatus 102 may be embodied as one or more servers, one or more desktop computers, one or more laptop computers, one or more mobile computers, one or more network nodes, multiple computing devices in communication with each other, any combination thereof, and/or the like. In this regard, the messaging apparatus 102 may be configured to provide a messaging service that a user of a remote computer may access over a network, such as the network 106 to facilitate engagement in messaging conversations with other users. For example, in such embodiments the messaging apparatus 102 may be configured to provide a messaging web service enabling a user of a remote computing device to access an online messaging application over the network 106 to enable the user to engage in messaging conversations with users of recipient apparatuses 104.
A recipient apparatus 104 may be embodied as any computing device, such as, for example, a desktop computer, laptop computer, server, mobile terminal, mobile computer, mobile phone, mobile communication device, game device, digital camera/camcorder, audio/video player, television device, radio receiver, digital video recorder, positioning device, wrist watch, portable digital assistant (PDA), any combination thereof, and/or the like. In this regard, the data processing apparatus 104 may comprise any computing device configured to engage in a messaging conversation with a user of a messaging apparatus 102 over the network 106. Accordingly, a recipient apparatus 104 may be configured to receive a message sent by the messaging apparatus 102 and to send a message to the messaging apparatus 102.
It will be appreciated that although the messaging apparatus 102 and recipient apparatus 104 are illustrated and described as distinct entities, such labeling and description is merely to facilitate description of various example embodiments. In this regard, a messaging apparatus 102 may be configured to function as a recipient apparatus in order to receive messages sent by a recipient apparatus 104 in a messaging conversation.

The memory 112 may comprise, for example, volatile memory, non-volatile memory, or some combination thereof. Although illustrated in FIG. 3 as a single memory, the memory 112 may comprise a plurality of memories. The plurality of memories may be embodied on a single computing device or on a plurality of computing devices collectively comprising the messaging apparatus 102. In various embodiments, the memory 112 may comprise, for example, a hard disk, random access memory, cache memory, flash memory, a compact disc read only memory (CD-ROM), digital versatile disc read only memory (DVD-ROM), an optical disc, circuitry configured to store information, or some combination thereof. In embodiments wherein the messaging apparatus 102 is embodied as a mobile terminal 10, the memory 112 may comprise the volatile memory 40 and/or the non-volatile memory 42. The memory 112 may be configured to store information, data, applications, instructions, or the like for enabling the messaging apparatus 102 to carry out various functions in accordance with example embodiments of the present invention. For example, in at least some embodiments, the memory 112 is configured to buffer input data for processing by the processor 110. Additionally or alternatively, in at least some embodiments, the memory 112 is configured to store program instructions for execution by the processor 110. The memory 112 may store information in the form of static and/or dynamic information. The stored information may, for example, comprise key word pairs, such as may be stored in a database. This stored information may be stored and/or used by the recipient determination circuitry 118 during the course of performing its functionalities.

In at least one embodiment, the communication interface 114 is at least partially embodied as or otherwise controlled by the processor 110. The communication interface 114 may, for example, be in communication with the processor 110, such as via a bus. The communication interface 114 may include, for example, an antenna, a transmitter, a receiver, a transceiver and/or supporting hardware or software for enabling communications with one or more entities of the system 100. The communication interface 114 may be configured to receive and/or transmit data using any protocol that may be used for communications between entities of the system 100. The communication interface 114 may additionally be in communication with the memory 112, user interface 116, and/or recipient determination circuitry 118, such as via a bus.
The user interface 116 may be in communication with the processor 110 to receive an indication of a user input and/or to provide an audible, visual, mechanical, or other output to a user. As such, the user interface 116 may include, for example, a keyboard, a mouse, a joystick, a display, a touch screen display, a microphone, a speaker, and/or other input/output mechanisms. In this regard, the user interface 116 may provide means to allow a user to enter a message to be sent to a recipient. The user interface 116 may further provide means for a user to view a message received from a recipient apparatus 104. In embodiments wherein the messaging apparatus 102 is embodied as one or more servers, aspects of the user interface 116 may be reduced or the user interface 116 may even be eliminated. In such embodiments wherein aspects of the user interface 116 are reduced or eliminated, user interface elements allowing a user to enter a message to be sent to a recipient apparatus 104 and view messages received from a recipient apparatus 104 may instead be embodied on a remote user terminal configured to access messaging services provided by the messaging apparatus 102 over the network 106. The user interface 116 may be in communication with the memory 112, communication interface 114, and/or recipient determination circuitry 118, such as via a bus.
The recipient determination circuitry 118 may be embodied as various means, such as circuitry, hardware, a computer program product comprising computer readable program instructions stored on a computer readable medium (for example, the memory 112) and executed by a processing device (for example, the processor 110), or some combination thereof and, in one embodiment, is embodied as or otherwise controlled by the processor 110. In embodiments wherein the recipient determination circuitry 118 is embodied separately from the processor 110, the recipient determination circuitry 118 may be in communication with the processor 110. The recipient determination circuitry 118 may further be in communication with one or more of the memory 112, communication interface 114, or user interface 116, such as via a bus.
In some example embodiments, the recipient determination circuitry 118 is configured to determine a message to be sent in one of a plurality of active messaging conversations. In this regard, a user may enter a message for transmission in one of a plurality of messaging conversations in which the user is engaged. Accordingly, a message to be sent in a messaging conversation may be intended to be sent to one or more parties participating in the conversation. The recipient determination circuitry 118 may be configured to use data from historical conversations to determine a conversation to which the message is relevant from among the active messaging conversations.
The data from historical conversations may, for example, comprise semantic relations between key words extracted from historical messaging conversations. In this regard, the data from historical conversations may be generated through analysis of historical conversations by a semantic word model configured to determine key word pairs binding two or more messages within a particular conversation as being related. Accordingly, the semantic relations may comprise key word pairs. A key word pair may comprise a pair of words determined to be related through analysis of historical conversations. In this regard, where a first key word in a key word pair appears in a first message and a second key word in a key word pair appears in a second message, there may be some likelihood that the first and second message are relevant to each other, such that they may belong in the same conversation.
As previously discussed, a messaging conversation is not limited to strictly text-based messaging. Accordingly, it will be appreciated that a word is not limited to a textual word recognized in a written language. In this regard, a word may comprise any kind of media unit utilized for various types of messaging. By way of example, a word may comprise a series of characters (e.g., a portion of a textual word), a plurality of words (e.g., a phrase), a sentence, a sentence fragment, multimedia content, an image, image data, a video frame, video data, a video clip, audio data, audio clip, an emoticon, other media unit, and/or the like. Accordingly, a key word pair may comprise any pairing of related media units.
When determining a conversation to which a message is relevant, the recipient determination circuitry 118 may be configured to iteratively select a conversation from a subset of the active messaging conversations and compare the content of the message to each of a subset of the previous messages in the selected conversations. In this regard, semantic key word data extracted from historical conversations may be used to determine whether there is a correlation between the message and one or more previous messages in an active conversation. In this regard, the message may be relevant to an active conversation if there is a correlation between the message and one or more previous messages in the active conversation.
In some example embodiments, the recipient determination circuitry 118 is configured to consider temporal information in addition to data from historical conversations when determining a conversation to which a message is relevant. The temporal information may comprise an interval between a message to be sent and a last received and/or sent message in an active conversation. In this regard, messages spaced closer in time may be more relevant to each other. Thus, for example, if a last message in a first conversation has a larger temporal gap to a message to be sent than a last message in a second conversation, the second conversation may be more relevant to the message to be sent.
In some example embodiments, the recipient determination circuitry 118 is configured to determine a degree of relevance of a message to be sent to each of a subset of the plurality of active messaging conversations. The recipient determination circuitry 118 may calculate a degree of relevance of a message to be sent to an active conversation based on any number of factors including. Example factors that may affect the degree of relevance of a message to a conversation include the temporal relationship of the message to the conversation, a number of semantic key word pairs found in a comparison of the message to one or more previous messages in the conversation, and/or the like. The recipient determination circuitry 118 may determine the active messaging conversation having the greatest degree of relevance to the message to be sent to be the conversation to which the message is relevant from among the active messaging conversations.
The recipient determination circuitry 118 may be further configured to designate a message to be sent to at least one recipient (for example, recipient apparatus 104) that is a party participating in the active conversation determined to be relevant (for example, most relevant) to the message. The number of designated recipients may depend on the number of parties to the relevant messaging conversation. For example, if the relevant messaging conversation is a two-party messaging conversation (e.g., a conversation to which the messaging apparatus 102 and a single recipient apparatus 104 are parties), a single recipient may be designated. If, however, the messaging conversation has more than two parties (e.g., a conversation to which the messaging apparatus 102 and a plurality of recipient apparatuses 104 are parties), such as a community chat conversation, the recipient determination circuitry 118 may designate multiple recipients.
In various embodiments, designating a message to be sent to a recipient may comprise automatically sending the message to the recipient and/or may comprise suggesting the recipient as the intended recipient to a user and requesting user confirmation before sending the message to the designated recipient. In embodiments wherein the recipient determination circuitry 118 is configured to calculate a degree of relevance of an active conversation to a message to be sent, the recipient determination circuitry 118 may be configured to automatically cause the message to be sent to a designated recipient when the degree of relevance of the message to the determined conversation meets a predefined threshold degree of relevance. When the relevance of the message to the determined conversation does not meet a predefined threshold degree of relevance, however, the recipient determination circuitry 118 may be configured to cause the determined conversation to be suggested to a user and seek user confirmation that the designated recipient is the user-intended recipient prior to sending the message.
FIG. 4 illustrates an example model that may be used by the recipient determination circuitry 118 for determining a message recipient according to an example embodiment of the invention. More particularly, FIG. 4 illustrates an example model for determining a recipient of an instant message according to an example embodiment. It will be appreciated, however, that the model illustrated in and described with respect to FIG. 4 may be modified to apply to messaging conversations other than instant messaging conversations. Referring now to FIG. 4, the recipient determination circuitry 118 may utilize an instant message (IM) receiver auto-detection model 404 to determine which of a plurality of active instant messaging conversations a message 402 (for example, a message to be sent) is related. Accordingly, in an example embodiment, the recipient determination circuitry 118 comprises and/or is configured to implement the elements of the model 404. In this regard, the model 404 may comprise a message relevance calculator and receiver selector 406. The message relevance calculator and receiver selector 406 may be configured to access previous messages and temporal information from active conversations (“active conversation data 408”) for purposes of analysis and comparison with the message 402. In this regard, the message relevance calculator and receiver selector 406 may be configured to utilize stored semantic relations between words 410 (“semantic relations 410”) to analyze and compare the message 402 to the active conversation data 408.
The semantic relations 410 may comprise a set of basic semantic related word pairs 416 and/or a set of semantic related word pairs generated by a semantic word pair training module 412 from past instant messaging conversation records 414. The set of basic semantic related word pairs 416 may, for example, comprise seed data used to initialize the model 404 to enable determination of a recipient for a message prior to collection of any messaging conversations. Accordingly, accuracy of the model 404 may be improved with continued use as additional messaging conversation records are collected and used for generation of semantic relations between words to supplement the basic semantic related word pairs 416
The message relevance calculator and receiver selector 406 may use the semantic relations 410 and the active conversation data 408 to calculate a degree of relevance of each active conversation in a subset of the active conversations to the message 402. The active conversation having the greatest calculated degree of relevance to the message 402 may be determined to be the conversation to which the message 402 is relevant and one or more recipient apparatuses 104 that are parties participating in the determined conversation may be designated as the receiver 418 of the message 402.
An example algorithm that may be used by the recipient determination circuitry 118 to determine a conversation to which a message is relevant may be described as follows:












Input: ConvSet: Set of the active conversations, C1,C2,...,Cn


M: Current message typed by a messaging user


Output: the most relevant Conversation to M, say ConvRel


 (1) MsgRel= NULL


 (2) FOR EACH conversation C ∈ ConvSet








 (3)
FOR EACH message m ∈ C








 (4)
IF MsgRel == NULL or Rel(M|m) > Rel(M|MsgRel)








 (5)
MsgRel=m








 (6)
END of IF








 (7)
END of FOR







 (8) END of FOR


 (9) Let ConvRel be the conversation that MsgRel belongs to


(10) RETURN ConvRel









In this example algorithm, Rel(M|m) is the function used to calculate the relevance between M (for example, the message to be sent) and m (for example, a previous message in an active conversation) based on semantic word pairs and message's temporal factor. As a reference, an example concrete function may be defined as:

Rel(M|m)=ΠqεMP(q|m)  [1],

where q is a word in M and P(q|m) is the probability of generating q from m based on the set of semantic related word pairs.

To avoid zero probabilities, linear interpolation may be used to smooth equation [1] as:

P(q|m)=(1−λ)Σwεmtran(q|w)Pml(w|m)+λpml(q|D)  [2],

where w is a word in m, and where tran(q|w) denotes the probability that word q is the translation of word w. D denotes the whole conversation collection. Suppose |D| and |m| are the total number of words in D and m, respectively. If tf(w,m) denotes the frequency of word w in m, tf(q,D) denotes the frequency of word q in D, then Pml(w|m)=tf(w,m)/|m|, Pml(q|D)=tf(q,D)/|D|. Using Pml(q|D), zero probabilities may be avoided. λ is a smoothing parameter, (for example 0.8). Given an assumption that tran(w|w)=1, the probability of self translation is always 1.

Based on equation [1], equation [3] for calculating the relevance between an incoming message and an active conversation by considering the message's temporal factor may be obtained:

may be applied to limit the influence of time, where α>0 (for example, α=2) is a parameter to control the temporal factor's influence.

The recipient determination circuitry 118 may be further configured to update stored data from historical conversations with data from an active conversation. In this regard, the recipient determination circuitry 118 may be configured to extract semantic key word pairs from an active conversation in order to update the extracted historical data. The recipient determination circuitry 118 may, for example, update the data from historical conversations with data from an active conversation upon completion (for example, termination) of the active conversation. As another example, the recipient determination circuitry 118 may update the data from historical conversations with data from an active conversation as messages are exchanged in the active conversation. As a further example, conversations may be at least temporarily archived in a message archive. Accordingly, the recipient determination circuitry 118 may be configured to periodically update the data from historical conversations with data from the message archive.
It will be appreciated that example embodiments described herein may be used in conjunction with a variety of messaging types and integrated into a variety of messaging interfaces. As one example, a common window or entry form may be provided for user entry of messages to be sent. Accordingly, even when a user is engaged in a plurality of messaging conversations, the user may enter all messages to be sent, regardless of the intended recipient, in a common message entry form. The recipient determination circuitry 118 may determine a conversation to which the message is relevant and designate the message to be sent to a recipient that is party participating in the determined conversation. In this regard, a user may not have to switch between several message entry windows in order to enter a message and have the message sent to an intended recipient.
As another example, each messaging conversation may be displayed in a separate window including a dedicated message entry form for entering messages to be sent in that conversation. The recipient determination circuitry 118 may be configured to verify that a message entered into the message entry form for a particular conversation is relevant to the conversation prior to sending the message to a recipient that is a party participating in the conversation. In this regard, if the recipient determination circuitry 118 determines that the message to be sent is not related to the conversation to which it is entered by the user, but rather is relevant to another active conversation, the recipient determination circuitry 118 may be configured to notify the user of a potential entry error and/or send the message in the correct conversation so as to reduce the risk of user error.
FIG. 5 illustrates a flowchart according to an example method for facilitating determination of a message recipient according to an example embodiment of the invention.

FIG. 6 illustrates a flowchart according to an example method for facilitating determination of a message recipient according to an example embodiment of the invention. \ The operations illustrated in and described with respect to FIG. 6 may, for example, be performed by with the assistance of, and/or under control of one or more of the processor 110, memory 112, communication interface 114, user interface 116, or recipient determination circuitry 118. Operation 600 may comprise determining a message to be sent in one of a plurality of active messaging conversations. Operation 610 may comprise determining a degree of relevance of the message to each of a subset of the plurality of active messaging conversations. Operation 620 may comprise determining the message to be relevant to the active messaging conversation having the greatest degree of relevance to the message. Operation 630 may comprise designating the message to be sent to at least one recipient. The at least one designated recipient may comprise at least one party (e.g., a recipient device 104 and/or user thereof) participating in the conversation determined in operation 620.
FIGS. 5-6 are flowcharts of a system, method, and computer program product according to example embodiments of the invention. It will be understood that each block of the flowcharts, and combinations of blocks in the flowcharts, may be implemented by various means, such as hardware and/or a computer program product comprising one or more computer-readable mediums having computer readable program instructions stored thereon. For example, one or more of the procedures described herein may be embodied by computer program instructions of a computer program product.

As such, then, some embodiments of the invention provide several advantages to computing devices, network providers, and computing device users. Some example embodiments determine to which of a plurality of active messaging conversations a message to be sent is relevant. Some such example embodiments determine which active messaging conversation a message is relevant to based at least in part upon data from historical conversations. Accordingly, some example embodiments enable determination of an appropriate recipient of a message by determining the conversation to which the message is relevant and designating the message to be sent to a recipient that is a party participating in the determined conversation. In this regard, some example embodiments utilize word correlation, such as based on one or more relevant word-to-word translation pairs accumulated from past messaging conversations, to calculate a semantic relevance between a message and an active conversation to facilitate determination of a target message recipient.
Users may particularly benefit from some example embodiments because a user may be able to enter messages to be sent in one of a plurality of active conversations without having to switch among different conversation windows. In this regard, in some example embodiments, a user may enter a message to be sent without designating a recipient for the message and the recipient may be determined by determining the conversation from among the plurality of active conversations to which the message has the greatest degree of relevance. Users may therefore benefit by not having to enter key strokes, mouse clicks, and/or other user input required to switch between active conversation windows to enter a message in a particular conversation window. Users may further benefit because some example embodiments may reduce the potential of a message being sent to the wrong recipient due to a user error resulting in a message being entered into a wrong conversation window. Network providers may benefit because some example embodiments may reduce the amount of excess data transfer that may occur if a user sends a message to an unintended recipient and then has to resend the message to the intended recipient. Some example embodiments may be easily and flexibly integrated into existing messaging applications and thus may be flexibly and rapidly deployed to improve the messaging experience of users of a variety of messaging platforms.
