SparTerm: Learning Term-based Sparse Representation for Fast Text Retrieval [article]

Yang Bai, Xiaoguang Li, Gang Wang, Chaoliang Zhang, Lifeng Shang, Jun Xu, Zhaowei Wang, Fangshan Wang, Qun Liu

Term-based sparse representations dominate the first-stage text retrieval in industrial applications, due to its advantage in efficiency, interpretability, and exact term matching.  ...  These two modules cooperatively ensure the sparsity and flexibility of the final text representation, which unifies the term-weighting and expansion in the same framework.  ...  Analysis of Term Weighting To further evaluate the ability of SparTerm on term weighting, we normalize the term weights of passages weighted by DeepCT and SparTerm(literal-only) to the same range and visulization  ...

Modeling higher-order term dependencies in information retrieval using query hypergraphs

Classical query expansion techniques such as the local context analysis (LCA) make use of term co-occurrence statistics to incorporate additional contextual terms for enhancing passage retrieval.  ...  Previous studies have demonstrated the importance of relationship analysis for natural language queries in passage retrieval.  ...  Traditional passage retrieval algorithms perform a density based weighting of query terms [4, 5, 9, 16] that prefer passages containing query terms that are close together.  ...

Query terms that distinguish well among documents in the database become candidate anchors; links are mediated by passage-based relevance feedback queries.  ...  In addition, large hyper-linked collections may overwhelm users with the range of possible links from any node, only a fraction of which may be appropriate for a given user at any time.  ...  ACKNOWLEDGMENTS This research was conducted as part of the author's Ph.D. research in the Department of Mechanical and Industrial Engineering at the University of Toronto.  ...

Many QA systems have been developed and most follow the same broad pattern of operation: first an information retrieval (IR) system, often passage-based, is used to find passages from a large document  ...  recall and precision measures, and (b) demonstrate their use in evaluating a variety of passage retrieval approaches using questions from TREC-9 and TREC 2001.  ...  These two approaches might lead to significantly different rankings of the same passages, and this difference could have important implications for QA.  ...
