SYSTEM AND METHOD FOR CHAT COMMUNITY QUESTION ANSWERING
A method, a system, and an article are provided for automatically posting answers to questions generated by users of a chat room. In one example, a set of chat messages is used to develop a database of question and answer pairs. When a subsequent chat message is identified as being similar or identical to a question in the database, the corresponding answer to the question can be retrieved from the database and posted in the chat room.
1 . A method, comprising:
receiving a stream of text messages for a chat messaging system, the stream of text messages comprising messages from a plurality of users of the chat messaging system;
processing each text message to generate a plurality of features for the text message;
providing the plurality of features for each text message to a question classifier trained to determine, based on the plurality of features, if the text message comprises a question;
identifying, using the question classifier, one or more questions in the text messages;
for each identified question, identifying in the stream of text messages a corresponding answer to the question;
storing, in a database, each identified question and corresponding answer;
determining that a subsequent text message in the stream of text messages comprises a question from the one or more questions;
retrieving, from the database, the corresponding answer to the question in the subsequent text message; and
posting the retrieved answer to the stream of messages for the chat messaging system.
2 . The method of claim 1 , wherein the plurality of features for each text message comprises a bag of words.
3 . The method of claim 1 , wherein identifying the one or more questions comprises:
determining that each question in the one or more questions relates to a software application used by the plurality of users.
4 . The method of claim 1 , wherein identifying the one or more questions in the text messages comprises:
clustering the one or more questions into one or more groups, each group comprising identical questions or similar questions.
5 . The method of claim 1 , wherein identifying the one or more questions in the text messages comprises:
identifying frequently asked questions among the identified one or more questions.
6 . The method of claim 1 , wherein identifying the corresponding answer comprises:
finding a message in the stream of text messages that is semantically similar to the question.
7 . The method of claim 1 , wherein identifying the corresponding answer comprises:
generating a pool of candidate answers that are semantically similar to the question; and
selecting a best answer from the pool of candidate answers.
8 . The method of claim 1 , wherein storing each identified question and corresponding answer comprises:
storing the identified question and corresponding answer in the database as a question and answer pair.
9 . The method of claim 1 , wherein determining that the subsequent text message comprises the question comprises:
processing the subsequent text message to generate a plurality of features for the subsequent text message;
using the question classifier to determine, based on the plurality of features for the subsequent text message, that the subsequent text message comprises a question; and
determining, based on the plurality of features, that the question in the subsequent text message is similar or identical to the question from the one or more questions.
10 . The method of claim 1 , further comprising:
obtaining a set of training messages for the question classifier, a portion of the training messages comprising questions;
processing each training message to generate a plurality of features for the training message; and
training the question classifier to recognize the questions in the training messages based on the plurality of features for the training messages.
11 . A system, comprising:
one or more computer processors programmed to perform operations comprising:
receiving a stream of text messages for a chat messaging system, the stream of text messages comprising messages from a plurality of users of the chat messaging system;
processing each text message to generate a plurality of features for the text message;
providing the plurality of features for each text message to a question classifier trained to determine, based on the plurality of features, if the text message comprises a question;
identifying, using the question classifier, one or more questions in the text messages;
for each identified question, identifying in the stream of text messages a corresponding answer to the question;
storing, in a database, each identified question and corresponding answer;
determining that a subsequent text message in the stream of text messages comprises a question from the one or more questions;
retrieving, from the database, the corresponding answer to the question in the subsequent text message; and
posting the retrieved answer to the stream of messages for the chat messaging system.
12 . The system of claim 11 , wherein identifying the one or more questions comprises:
determining that each question in the one or more questions relates to a software application used by the plurality of users.
13 . The system of claim 11 , wherein identifying the one or more questions in the text messages comprises:
clustering the one or more questions into one or more groups, each group comprising identical questions or similar questions.
14 . The system of claim 11 , wherein identifying the one or more questions in the text messages comprises:
identifying frequently asked questions among the identified one or more questions.
15 . The system of claim 11 , wherein identifying the corresponding answer comprises:
finding a message in the stream of text messages that is semantically similar to the question.
16 . The system of claim 11 , wherein identifying the corresponding answer comprises:
generating a pool of candidate answers that are semantically similar to the question; and
selecting a best answer from the pool of candidate answers.
17 . The system of claim 11 , wherein storing each identified question and corresponding answer comprises:
storing the identified question and corresponding answer in the database as a question and answer pair.
18 . The system of claim 11 , wherein determining that the subsequent text message comprises the question comprises:
processing the subsequent text message to generate a plurality of features for the subsequent text message;
using the question classifier to determine, based on the plurality of features for the subsequent text message, that the subsequent text message comprises a question; and
determining, based on the plurality of features, that the question in the subsequent text message is similar or identical to the question from the one or more questions.
19 . The system of claim 11 , further comprising:
obtaining a set of training messages for the question classifier, a portion of the training messages comprising questions;
processing each training message to generate a plurality of features for the training message; and
training the question classifier to recognize the questions in the training messages based on the plurality of features for the training messages.
20 . An article, comprising:
a non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more computer processors, cause the one or more computer processors to perform operations comprising:
receiving a stream of text messages for a chat messaging system, the stream of text messages comprising messages from a plurality of users of the chat messaging system;
processing each text message to generate a plurality of features for the text message;
providing the plurality of features for each text message to a question classifier trained to determine, based on the plurality of features, if the text message comprises a question;
identifying, using the question classifier, one or more questions in the text messages;
for each identified question, identifying in the stream of text messages a corresponding answer to the question;
storing, in a database, each identified question and corresponding answer;
determining that a subsequent text message in the stream of text messages comprises a question from the one or more questions;
retrieving, from the database, the corresponding answer to the question in the subsequent text message; and
posting the retrieved answer to the stream of messages for the chat messaging system.
