Answer Extraction by Flexible Matching, Filtering, and Interpretation [chapter]

Kyung-Soon Lee, Jae-Ho Kim, Key-Sun Choi
2002 Lecture Notes in Computer Science  
In answer extraction, we filter non-fact answers with negative or uncertain contexts, and interpret a relative expression as an absolute date answer for date type question.  ...  Through component analysis, we show that terms need to be matched flexibly according to their characteristics, answer filter make a system more reliable, and answer interpretation make a system more intelligent  ...  Acknowledgments This research was conducted while I was a PhD student at KAIST (Korea Advanced Institute of Science and Technology) and supported by the Korean Ministry of Science and Technology.  ...

FAQ-based Question Answering via Knowledge Anchors [article]

Ruobing Xie, Yanan Lu, Fen Lin, Leyu Lin
2020 arXiv   pre-print
The multi-channel matching strategy also enables most sentence matching models to be flexibly plugged in our KAQA framework to fit different real-world computation limitations.  ...  Question answering (QA) aims to understand questions and find appropriate answers.  ...  Inspired by Siamese network, DSSM [6] and Arc-I [5] extract high-order features and then calculate similarities in semantic spaces.  ...

2016 Spatial Information Research  
The approach is demonstrated with a proof of concept web interface, developed to interpret a text query to find and show bus stop locations within a named boundary by coordinating multiple online search  ...  Some online tools circumvent these problems by putting more filter controls into the hands of users, but this leads to more complex interfaces which can raise usability barriers.  ...  ACKNOWLEDGEMENTS The research reported in this paper was supported by the Australian Primary Health Care Research Institute (APHCRI), which was supported by a grant from the Australian Government Department  ...

2013 IEEE 7th International Conference on Research Challenges in Information Science (RCIS)  
It bases on popular standards like RDF and SparQL and is therefore very easy to adapt to other domains or usecases.  ...  In our experiments, we demonstrate that with our approach one can easily achieve a similar answering quality as one of the most popular Q&A systems on the Web.  ...  It does not match our running example question to underline the power and flexibility of the described mechanism.  ...

Answering natural language queries over linked data graphs

André Freitas, Fabrício F. de Faria, Seán O'Riain, Edward Curry
2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
The approach uses a distributional semantic vector space model to semantically match user query terms with data, supporting vocabularyindependent (or schema-agnostic) queries over structured data.  ...  This query also returns related triples which are not the answer for the query but which can be quickly filtered by users.  ...  In the query pre-processing phase the natural language query is analyzed by the Interpreter component, where a set of query patterns and features are detected in the user query.  ...
