## Abstract

Techniques, systems, and articles of manufacture for determining the current logical state of a social media communication thread. A method includes computing an initial probability for applicability of each of multiple logical states for a first entry in a social media communication thread, wherein each logical state corresponds to a stage of interaction between customers of an enterprise and/or agents of the enterprise based on features derived from content of entries in the communication thread, network structure of entries, and identity of authors of entries, computing a transition probability between each subsequent consecutive entry in the communication thread, wherein the transition probability indicates the probability of moving from one logical state to another, and determining the current logical state of the communication thread based on the computed initial probability for the first entry and the computed transition probability between each subsequent entry in the communication thread.

## Background
FIELD OF THE INVENTION
Embodiments of the invention generally relate to information technology, and, more particularly, to customer relationship management over social media channels.
BACKGROUND
As social customer relationship management (CRM) becomes more prevalent, tools, techniques and protocols will be required to manage the threaded and collaborative communications conducted on social media forums. Threaded and public communication on such forums can, for example, result in fellow community members solving problems, and reducing the burden on corporate social responsibility (CSR). However, a negative reaction on such a forum, if not addressed in a timely manner and/or with proper care, can lead to a chain of negative reactions. Accordingly, given the potential for considerable amounts of noise on such forums, a need exists for providing efficient solutions to prioritize, open, close and reopen cases identified on social media forums that pertain to customer relations.
SUMMARY
In one aspect of the present invention, techniques for determining the current logical state of a social media communication thread are provided. An exemplary computer-implemented method for determining one or more logical states of a communication thread includes steps of computing an initial probability for applicability of each of multiple logical states for a first entry in a social media communication thread, wherein each logical state corresponds to a stage of interaction between one or more customers of an enterprise and/or one or more agents of the enterprise based on one or more features derived from content of one or more entries in the communication thread, network structure of one or more entries in the communication thread, and identity of one or more authors of one or more entries in the communication thread. The method also includes computing a transition probability between each subsequent consecutive entry in the communication thread, wherein the transition probability indicates the probability of moving from one logical state to another logical state, and determining the current logical state of the communication thread based on the computed initial probability for the first entry and the computed transition probability between each subsequent entry in the communication thread from the first entry to a current entry.
In another aspect of the invention, an exemplary computer-implemented method for automatically determining a current logical state of a threaded communication can include steps of computing an initial probability for applicability of each of multiple logical states for a first entry in a social media communication thread, wherein each logical state corresponds to a stage of interaction between one or more customers of an enterprise and/or one or more agents of the enterprise based on one or more features derived from content of one or more entries in the communication thread, network structure of one or more entries in the communication thread, and identity of one or more authors of one or more entries in the communication thread. The method can also include computing a transition probability between each subsequent consecutive entry in the communication thread, wherein the transition probability indicates the probability of moving from one logical state to another logical state, automatically determining the current logical state of the communication thread based on the computed initial probability for the first entry and the computed transition probability between each subsequent entry in the communication thread from the first entry to a current entry, and executing an action in connection with the threaded communication based on the determined current logical state of the threaded communication.
Another aspect of the invention or elements thereof can be implemented in the form of an article of manufacture tangibly embodying computer readable instructions which, when implemented, cause a computer to carry out a plurality of method steps, as described herein. Furthermore, another aspect of the invention or elements thereof can be implemented in the form of an apparatus including a memory and at least one processor that is coupled to the memory and operative to perform noted method steps.
Yet further, another aspect of the invention or elements thereof can be implemented in the form of means for carrying out the method steps described herein, or elements thereof; the means can include hardware module(s) or a combination of hardware and software modules, wherein the software modules are stored in a tangible computer-readable storage medium (or multiple such media).

DETAILED DESCRIPTION
As described herein, an aspect of the present invention includes techniques for inferring a current logical state of a threaded communication. As detailed herein, a threaded communication implies a multi-party communication initiated by a community member and subsequently responded to or commented on by fellow community members. The subsequent responses (also referred to herein as entries) themselves may appear in response to either the first entry or any of the entries made up to that point in the communication thread. A logical state is characterized by the logical action intended when that state is reached. In an example context, these states can be defined on the basis of what logical actions an enterprise would like to take for the threaded communications in question.
At least one embodiment of the invention includes leveraging content features and threaded structure of a communication, and integrating human knowledge with a machine learning algorithm to provide an automated mechanism to determine and/or infer the logical current state of a threaded communication. By way of illustration, in an example embodiment of the invention, logical states can include “Respond,” “Do Not Respond,” “Closed,” and “Awaiting More Information.”
Additionally, at least one embodiment of the invention includes utilizing sequence analysis algorithms such as Hidden Markov Models (HMMs), Conditional Random Fields (CRFs), etc. As also detailed further herein, at least one embodiment of the invention includes training and runtime phases. During a training phase, data can be labeled in terms of threads and states, and used for inferring parameters of the model. During a runtime phase, the trained model can be used for determining and/or identifying the most likely logical state sequence of a particular communication.
Accordingly, aspects of the invention include leveraging the sequential and collaborative nature of threaded communications, as well as fusing human knowledge with machine learning techniques to automatically to derive a current logical state of a communication thread.
FIG. 1 is a diagram illustrating an example threaded communication and possible logical states, according to an embodiment of the invention. Specifically, FIG. 1 depicts a communication thread 102 (for example, from a social media forum) and a set of logical states 104. As noted above and further used herein, logical states can include respond (R), awaiting more information (AW), closed (C), and do not respond (DR).
In thread 102, Post 1 includes a complaint by Customer 1, which is related and/or relevant to Issue 1 on the main post. As used subsequently herein, the first entry in a communication thread can also be referred to as the main post or the root post. The corresponding logical state in connection with Post 1 is State 1, which is a “Respond” state. This indicates that, at this point in the communication thread, when only the first entry is observed, the action most suited for an enterprise to take would be to “respond,” and that is why the threaded communication is noted as in the “respond” state. After observing a few more exchanges or entries, if it turns out that the issue raised in the main post has been resolved, the action an enterprise should take at that point is to “wait for more information,” and, accordingly, the threaded communication would be marked as in the “awaiting more information” state. Further, if a positive satisfactory response appears from the author of the main post, the threaded communication can be marked as in a “closed” state, indicating that there are no remaining tasks to be carried out at that point.
Additionally, in thread 102, Post 2 includes a response by Customer 2, which is not relevant to Issue 1. The corresponding logical state in connection with Post 2 is State 2, which is a “Respond” state. Post 3 in thread 102 includes a response by an Agent, which is relevant to Issue 1. The corresponding logical state in connection with Post 3 is State 3, which is an “Awaiting More Information” state. As noted herein, a state is said to be in the “awaiting more information” state when the person who initiated the complaint has not yet acknowledged a full closure of the problem. It is also possible, for example, that the enterprise agent, in his or her response, has asked for more information (such as the date of a purchase) and is waiting for the customer, who is also the author of the main post, to provide that information.
Post 4 includes a question by Customer 3, wherein the question brings up Issue 2 in the communication. The corresponding logical state in connection with Post 4 is State 4, which is a “Respond” state. Post 5 includes a required response by the Agent, wherein the response is relevant to Issue 2. The corresponding logical state in connection with Post 5 is State 5, which is an “Awaiting More Information” state. The agent is now waiting for information from either customer 1 or customer 3, depending on the exact nature of the communication.
FIG. 2 is a block diagram illustrating an example embodiment, according to an aspect of the invention. By way of illustration, FIG. 2 depicts one or more social media forums 202, which provide input to a database 204. The database stores threaded communications, related metadata, agent responses, relevant logical current states, etc. FIG. 2 also depicts a most recent portion (or slice) 206 provided by the database 204. The most recent “slice” includes all of the entries made during a predefined duration of time (for example, one hour), ending at the current time instant. The most recent portion or slice 206 can be parsed into new threads 208 and posts 210 written to existing threads. Posts written to existing threads refer to those entries which were made in response to one of the entries made prior to the most recent slice.
In the new threads 208, there are only two logical states 212 possible, “Respond” and “Do Not Respond,” given that there is no further dialogue with the customer. Note that the “Awaiting more information” and the “Closed” states are only possible after a dialogue between the author of the main post and either the community or the enterprise. In the posts 210 written to existing threads, a logical state is detected 214 from the set of logical states 216 (“Respond,” “Do Not Respond,” “Closed,” or “Awaiting More Information”). In the example depicted in FIG. 2, the state of “Awaiting More Information” 218 is ultimately identified. This most current logical state 218 is stored in the database 204 to be used for future analysis, that is, analysis of slices later in time.
FIG. 3 is a diagram illustrating an example training technique, according to an embodiment of the invention. By way of illustration, FIG. 3 depicts Post 0, Post 1, Post 2 and Post n, which are provided as input into a feature (f) extraction component 302. The feature extraction component 302 identifies elements in the communication content such as, for example, positive sentiments, negative sentiments, domain words, a post index, thread length, identification of a same author, etc. An example logical state training sequence, such as depicted in FIG. 3, can include a beginning point 304, a “Respond” state 306, a “Do Not Respond” state 308, an “Awaiting More Information” state 310, and a “Closed” state 312.
More specifically, in the example depicted in FIG. 3, during training, at least one embodiment of the invention includes learning initial probabilities, I1 and I2, wherein I1 is the initial probability that a “Respond” state is applicable based on the relevant portion(s) of the communication thread, and I2 is the initial probability that a “Do Not Respond” state is applicable based on the relevant portion(s) of the communication thread. These probabilities can be computed, for example, based on how many times in the training data a threaded communication starts with a “Respond” or “Do Not Respond” state.
Additionally, at least one embodiment of the invention includes learning the transition probabilities, for example, T1 through T6. A transition probability is defined between two states and indicates the probability of moving from one state to another. In the case of HMMs, for example, training algorithms such as Baum-Welch can be used for this purpose. However, it is to be appreciated that embodiments of the present invention are not limited to only HMM algorithmic possibilities. Subsequently, probability distributions, P(feature|state), can be calculated using labeled data (post, state). By way of example, in the case of HMMs, the Baum-Welch algorithm can be used. However, it is to be appreciated that any other sequence modeling approach can be used for this purpose. In the case of HMM, for example, all of the features corresponding to one state are analyzed together to compute the distribution P(feature|State).
Further, during runtime, at least one embodiment of the invention includes computing likelihoods P(feature|state) of current logical states. In contrast to the training phase, wherein P(feature|State) is determined—that is, the parameters required to estimate P(feature|State) were estimated—in the runtime phase, P(feature|State) is actually used to compute a probability value.
Also, at least one embodiment of the invention includes determining and/or identifying the most likely state sequence that maximizes the joint likelihood of the sequence as well as the extracted features. Accordingly, at least one embodiment of the invention includes exploiting information from i) the sequence of the communication to a current point, and ii) the content of each entry. Consider, for example, a scenario where it becomes clear that the second entry in a communication thread is an “Answer.” Knowing that the second entry is an answer reinforces the belief that the first entry was a “Question,” even though that might not have been apparent from the content of the first entry. The sequence of the communication is characterized by the transition probabilities, whereas the content of the entries is characterized by the features and the probability distributions P(feature|state). An algorithm such as, for example, the Viterbi decoding algorithm can efficiently determine the optimal state sequence, exploiting the two above-noted factors. It is to be appreciated that any other sequence model (for example, CRF) can be also used for this purpose.
FIG. 4 is a flow diagram illustrating techniques for determining the current logical state of a social media communication thread, according to an embodiment of the present invention. Step 402 includes computing an initial probability for applicability of each of multiple logical states for a first entry in a social media communication thread, wherein each logical state corresponds to a stage of interaction between one or more customers of an enterprise and/or one or more agents of the enterprise based on one or more features derived from content of one or more entries in the communication thread, network structure of one or more entries in the communication thread, and identity of one or more authors of one or more entries in the communication thread. Computing an initial probability can include computing the initial probability of each logical state for the first entry based on the number of times in a set of training data that a communication thread starts with a first state (for example, a “Respond” state) or a second state (for example, a “Do Not Respond” state).
Step 404 includes computing a transition probability between each subsequent consecutive entry in the communication thread, wherein the transition probability indicates the probability of moving from one logical state to another logical state. Computing a transition probability can include incorporating human knowledge in terms of one or more allowable transitions.
Step 406 includes determining the current logical state of the communication thread based on the computed initial probability for the first entry and the computed transition probability between each subsequent entry in the communication thread from the first entry to a current entry. The techniques depicted in FIG. 4 can also include storing the communication thread (along with one or more items or relevant metadata) and the determined logical state for each entry in the communication thread in a database.
The techniques depicted in FIG. 4 can also include extracting at least one feature for each entry in a communication thread, wherein said extracting is based on the content of each entry. As described herein, a threaded communication can include a multi-party communication initiated by a first user or community member and subsequently responded to and/or commented on by one or more fellow users or community members.
FIG. 5 is a flow diagram illustrating techniques for automatically determining the current logical state of a social media communication thread, according to an embodiment of the invention. Step 502 includes computing an initial probability for applicability of each of multiple logical states for a first entry in a social media communication thread, wherein each logical state corresponds to a stage of interaction between one or more customers of an enterprise and/or one or more agents of the enterprise based on one or more features derived from content of one or more entries in the communication thread, network structure of one or more entries in the communication thread, and identity of one or more authors of one or more entries in the communication thread.
Step 504 includes computing a transition probability between each subsequent consecutive entry in the communication thread, wherein the transition probability indicates the probability of moving from one logical state to another logical state. Step 506 includes automatically determining the current logical state of the communication thread based on the computed initial probability for the first entry and the computed transition probability between each subsequent entry in the communication thread from the first entry to a current entry.
The techniques depicted in FIG. 5 also include extracting at least one feature for each entry in a communication thread, wherein said extracting is based on the content of each entry. Automatically determining a current logical state can include determining a logical state sequence among the entries in the communication thread with the highest likelihood based on the one or more features identified.
Step 508 includes executing an action in connection with the threaded communication based on the determined current logical state of the threaded communication. Executing an action can include, for example, automatically prioritizing an action item in a customer relationship management system based on the determined logical states, automatically reopening an action item in a customer relationship management system based on the determined logical states, and/or automatically closing an action item in a customer relationship management system based on the determined logical states.
The techniques depicted in FIG. 4 and FIG. 5 can also, as described herein, include providing a system, wherein the system includes distinct software modules, each of the distinct software modules being embodied on a tangible computer-readable recordable storage medium. All of the modules (or any subset thereof) can be on the same medium, or each can be on a different medium, for example. The modules can include any or all of the components shown in the figures and/or described herein. In an aspect of the invention, the modules can run, for example, on a hardware processor. The method steps can then be carried out using the distinct software modules of the system, as described above, executing on a hardware processor.

Additionally, the techniques depicted in FIG. 4 and FIG. 5 can be implemented via a computer program product that can include computer useable program code that is stored in a computer readable storage medium in a data processing system, and wherein the computer useable program code was downloaded over a network from a remote data processing system. Also, in an aspect of the invention, the computer program product can include computer useable program code that is stored in a computer readable storage medium in a server data processing system, and wherein the computer useable program code is downloaded over a network to a remote data processing system for use in a computer readable storage medium with the remote system.
