Automatic suggestion of phrasal-concept queries for literature search

Youngho Kim, Jangwon Seo, W. Bruce Croft, David A. Smith
2014 Information Processing & Management  
In the specific domain of literature search (e.g., finding academic papers), the initial queries are usually based on a draft paper or abstract, rather than short lists of keywords.  ...  The merits of phrasal-concept query suggestions for this domain are their readability and retrieval effectiveness: (1) phrasal concepts are natural for academic authors because of their frequent use of  ...  Any opinions, findings and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect those of the sponsor.  ...

Selecting expansion terms as a set via integer linear programming

Qi Zhang, Yan Wu, Xuanjing Huang
2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12  
Pseudo-relevance feedback via query expansion has been widely studied from various perspectives in the past decades.  ...  In this paper, we first examine the influence of combinations of terms through data analysis, which demonstrate the significant effect of term-to-term relationship on retrieval effectiveness.  ...  Pseudo-relevance feedback (PRF) is one of the most attractive and well-known expansion techniques.  ...

A quantitative evaluation of query expansion in domain specific information retrieval

Mitra Akasereh
2013 Proceedings of the American Society for Information Science and Technology  
Our results show that expansion with both pseudo-relevant documents and external resources improve the retrieval. While the impact of expansion using an external resource is more significant.  ...  To do so we considered different strategies based on blind-query expansion as well as using external resource, namely Wikipedia.  ...  ACKNOWLEDGMENTS This work was supported in part by the Swiss NSF under Grant #200020-129535/1.  ...

Query Expansion Techniques for Information Retrieval: a Survey [article]

Hiteshwar Kumar Azad, Akshay Deepak
2017 arXiv   pre-print
With the ever increasing size of web, relevant information extraction on the Internet with a query formed by a few keywords has become a big challenge.  ...  It has also become very influential in the field of personalized social document, Question Answering over Linked Data (QALD), and, Text Retrieval Conference (TREC) and REAL sets.  ...  A recent work [243] uses fuzzy logic-based query expansion techniques and selects top-retrieved documents based on pseudo-relevance feedback.  ...

Sources of evidence for vertical selection

Jaime Arguello, Fernando Diaz, Jamie Callan, Jean-Francois Crespo
2009 Proceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '09  
We focus on three sources of evidence: (1) the query string, from which features are derived independent of external resources, (2) logs of queries previously issued directly to the vertical, and (3) corpora  ...  We address the problem of vertical selection, predicting relevant verticals (if any) for queries issued to the search engine's main web search page.  ...  Any opinions, findings, conclusions, and recommendations expressed in this paper are the authors' and do not necessarily reflect those of the sponsors.  ...
