Exploiting Synonyms to Improve Question and Answering Systems

چکیده
Community Question and Answering (CQA) systems are a popular way for Internet users to get answers to complex and common everyday questions. One of the challenges with CQA is that some of the asked questions are not answered [8]. This paper addresses this challenge by using a synonym-based approach that expands each unanswered question into several related questions. This paper argues that the number of unanswered questions can be reduced by searching the data set for the most similar resolved question(s) (questions that have been satisfactorily answered) to either the unanswered question and / or any of its expanded questions. If this search returns more than one resolved question, we rank the returned questions and choose the highest ranking resolved question as the most similar to the unanswered question.

Optimizing question answering systems by Accelerated Particle Swarm Optimization (APSO)
One of the most important research areas in natural language processing is Question Answering Systems (QASs). Existing search engines, with Google at the top, have many remarkable capabilities. But there is a basic limitation (search engines do not have deduction capability), a capability which a QAS is expected to have. In this perspective, a search engine may be viewed as a semi-mechanized QA...

متن کاملQuestion categorization for a question answering system using a vector space model
The purpose of the thesis is to assign questions to sense categories, where the sense categories are represented by predefined paraphrase sets of questions. The paraphrase sets are available for each domain in the Question Answering system and consist of different framings of questions that will lead to the same answer in the Question Answering system. A Java program was developed for the categ...
