Abstract
In this paper, we propose a new approach to extracting question-context-answer triples from online discussion forums. More specifically, we propose a general framework based on Conditional Random Fields (CRFs) for context and answer detection, and also extend the basic framework to utilize contexts for answer detection and to better accommodate the features of forums.

A system for discovering questions and answers in a forum stored in a database, the system comprising:
- a component for identifying questions from text entries of the database, wherein the questions are identified using a classification method configured to identify questions from forum data as focuses of a thread;
- and
- a component for identifying contexts and answers from text sections of the database, wherein the contexts and answers are identified by the use of conditional random fields, and wherein the component for identifying answers is configured to capture the relationships between contiguous sentences, the component for identifying answers is also configured to produce a list of ranked candidate answers for the identified questions.
A method for discovering questions and answers, the method comprising:
- identifying questions from text entries of the database, wherein the questions are identified using a classification method configured to identify questions from forum data as focuses of a thread;
- and
- identifying contexts and answers from text sections of the database, wherein the contexts and answers are identified by the use of conditional random fields, and wherein the component for identifying answers is configured to capture the relationships between contiguous sentences, the component for identifying answers is also configured to produce a list of ranked candidate answers for the identified questions.
A computer-readable storage media comprising computer executable instructions to, upon execution, perform a process for discovering questions and answers, the process including:
- identifying questions from text entries of the database, wherein the questions are identified using a classification method configured to identify questions from forum data as focuses of a thread;
- and
- identifying contexts and answers from text sections of the database, wherein the contexts and answers are identified by the use of conditional random fields, and wherein the component for identifying answers is configured to capture the relationships between contiguous sentences, the component for identifying answers is also configured to produce a list of ranked candidate answers for the identified questions.
