Demand for Question Answering systems is increasing day by day since they deliver short, precise and question specific answers. Huge amount of redundant data from irrelevant documents through the World Wide Web has given rise to an Information Technology (IT) Question Answering system to be used by secondary students. The main aim of developing such a system is to allow students obtain concise and...
Using SMS (Short Message System), cell phones can be used to query for information about various topics. In an SMS based search system, one of the key problems is to identify a domain (broad topic) associated with the user query; so that a more comprehensive search can be carried out by the domain specific search engine. In this paper we use a rule based approach, to identify the domain, called Short...
FAQ system is a QA retrieval system which finds the question sentence from question-answer collection and then returns its corresponding answer to user. The task of matching questions to corresponding question-answer pairs has become a major challenge in FAQ system. In this context, we address the problem by using a semantic knowledge base, namely, word co-occurrence corpus, to improve its ability...
Extracting question-answer pairs from online forums is a meaningful work due to the huge amount of valuable user generated resource contained in forums. In this paper we consider the problem of extracting Chinese question-answer pairs for the first time. We present a strategy to detect Chinese questions and their answers. We propose a sequential rule based method to find questions in a forum thread,...
Open domain question answering (QA) represents a challenge of natural language processing, aiming at returning exact answers in response to natural language questions. Recently, it has been found that pattern matching is an effective strategy for QA. The technique of pattern optimization and its applications in QA are demonstrated in the paper. Named entity recognition is used to optimize the answer...
While semantic search technologies have been proven to work well in specific domains, they still have to confront two main challenges to scale up to the Web in its entirety. In this work we address this issue with a novel semantic search system that a) provides the user with the capability to query Semantic Web information using natural language, by means of an ontology-based Question Answering (QA)...
