Web Based Pattern Mining and Matching Approach to Question Answering

Dell Zhang, Wee Sun Lee
2002 Text Retrieval Conference  
We describe herein a Web based pattern mining and matching approach to question answering.  ...  Given a new unseen question, these textual patterns can be utilized to extract and rank the plausible answers on the Web.  ...  The power of textual patterns for question answering looks quite amazing and stimulating to us. We describe herein a Web based pattern mining and matching approach to question answering.  ...

Factoid Question Answering over Unstructured and Structured Web Content

Silviu Cucerzan, Eugene Agichtein
2005 Text Retrieval Conference  
For unstructured content, we used a web-based system with novel features such as web snippet pattern matching and generic answer type matching using web counts.  ...  This system attempts to answer factoid questions by guessing relevant rows and fields in matching web tables and integrating the results. We believe a combination of the two approaches holds promise.  ...  Acknowledgments We thank MSN Search for providing us access to their search engine. We also thank Eric Brill for extremely valuable discussions and feedback on this work.  ...

Question answering from the web using knowledge annotation and knowledge mining techniques

Jimmy Lin, Boris Katz
2003 Proceedings of the twelfth international conference on Information and knowledge management - CIKM '03  
Knowledge annotation is an approach to answering large classes of frequently occurring questions by utilizing semistructured and structured Web sources.  ...  Our approach, implemented in a system called Aranea, extracts answers from the Web using two different techniques: knowledge annotation and knowledge mining.  ...  Exact queries in Aranea are generated by approximately a dozen pattern matching rules based on query terms and their part-of-speech tags; morpho-lexical pattern matches trigger the creation of reformulated  ...

A survey on question answering systems with classification

Amit Mishra, Sanjay Kumar Jain
2016 Journal of King Saud University: Computer and Information Sciences  
Question answering systems (QASs) generate answers of questions asked in natural languages. Early QASs were developed for restricted domains and have limited capabilities.  ...  To identify the future scope of research in this area, the need of a comprehensive survey on QASs arises naturally. This paper surveys QASs and classifies them based on different criteria.  ...  These are: Statistical based approach, Rule based pattern matching approach and hybrid approach. Statistical based approach: these are a data driven approach.  ...
