Using Coreference to Improve Passage Retrieval for Question Answering
نویسنده
چکیده
We present a system which retrieves answers to queries based on term weighting supplemented by coreference relationships between entities in a document. An evaluation of this system is given which demonstrates that the coreference relationships allov~ significantly more questions to be answered than with a baseline system which doesn’t model these relationships.

Boosting Passage Retrieval through Reuse in Question Answering
Question Answering (QA) is an emerging important field in Information Retrieval. In a QA system the archive of previous questions asked from the system makes a collection full of useful factual nuggets. This paper makes an initial attempt to investigate the reuse of facts contained in the archive of previous questions to help and gain performance in answering future related factoid questions. I...
متن کاملSimple is Best: Experiments with Different Document Segmentation Strategies for Passage Retrieval
Passage retrieval is used in QA to filter large document collections in order to find text units relevant for answering given questions. In our QA system we apply standard IR techniques and index-time passaging in the retrieval component. In this paper we investigate several ways of dividing documents into passages. In particular we look at semantically motivated approaches (using coreference c...

Passage retrieval is an essential part of question answering systems. In this paper we use statistical language models to perform this task. Previous work has shown that language modeling techniques provide better results for both, document and passage retrieval. The motivation behind this paper is to define new smoothing methods for passage retrieval in question answering systems. The final ob...

متن کاملApplying Data Fusion Methods to Passage Retrieval in QAS
This paper investigates the use of diverse data fusion methods to improve the performance of the passage retrieval component in a question answering system. Our results obtained with 13 data fusion methods and 8 passage retrieval systems show that data fusion techniques are capable of improving the performance of a passage retrieval system by 6.43% and 11.32% in terms of the mean reciprocal ran...
