An alternative approach to natural language query expansion in search engines: Text analysis of non-topical terms in Web documents

Rahmatollah Fattahi, Concepción S. Wilson, Fletcher Cole
2008 Information Processing & Management  
This paper presents a new approach to query expansion in search engines through the use of general non-topical terms (NTTs) and domain-specific semi-topical terms (STTs).  ...  Our findings suggest that web searching could be greatly enhanced combining NTTs (and STTs) with TTs in an initial query.  ...  Acknowledgement This work was funded, in part, by the John Metcalfe Visitor's Grant awarded to the first author, Rahmatollah Fattahi.  ...

Linggle: a Web-scale Linguistic Search Engine for Words in Context

Joanne Boisson, Ting-hui Kao, Jian-Cheng Wu, Tzu-Hsi Yen, Jason S. Chang
2013 Annual Meeting of the Association for Computational Linguistics  
In this paper, we introduce a Web-scale linguistics search engine, Linggle, that retrieves lexical bundles in response to a given query.  ...  We plan to extend Linggle to provide fast and convenient access to a wealth of linguistic information embodied in Web scale datasets including Google Web 1T and Google Books Ngram for many major languages  ...  Related work Web-scale Linguistic Search Engine (LSE) has been an area of active research. Recently, the state-of-the-art in LSE research has been re-viewed in Fletcher (2012) .  ...

A knowledge-based search engine powered by wikipedia

David N. Milne, Ian H. Witten, David M. Nichols
2007 Proceedings of the sixteenth ACM conference on Conference on information and knowledge management - CIKM '07  
Koru exhibits an understanding of the topics of both queries and documents. This allows it to (a) expand queries automatically and (b) help guide the user as they evolve their queries interactively.  ...  It was capable of lending assistance to almost every query issued to it; making their entry more efficient, improving the relevance of the documents they return, and narrowing the gap between expert and  ...  an alternative title of an article with the preferred one.  ...

Introducing lateral thinking in search engines

Yann Landrin-Schweitzer, Pierre Collet, Evelyne Lutton
2006 Genetic Programming and Evolvable Machines  
This common statement applies to huge databases, where state of the art search engines may retrieve hundreds of very similar documents for a precise query.  ...  User queries are rewritten with the help of the user profile, then the database is searched with the set of rewritten queries and presented to the user as a list of documents, in the same way as any usual  ...  Acknowledgements The authors are grateful to Thierry Prost, MD, PhD, for his educated analysis of the innards of ELISE.  ...

Building Better Search Engines by Measuring Search Quality

Ellen M. Voorhees, Paul Over, Ian Soboroff
2014 IT Professional Magazine  
Origins of TREC Today we take search for text documents in our native language for granted, but web search engines such as Yahoo, Google, and Bing were not built in a day, nor is web content the only area  ...  Search engines are developed using standard sets of realistic test cases that allow developers to measure the relative effectiveness of alternative approaches.  ...  document set and a natural language statement of an information need, called a topic.  ...

A survey of Web clustering engines

Claudio Carpineto, Stanislaw Osiński, Giovanni Romano, Dawid Weiss
2009 ACM Computing Surveys  
Web clustering engines organize search results by topic, thus offering a complementary view to the flat-ranked list returned by conventional search engines.  ...  We discuss how to compare the retrieval effectiveness of a clustering engine to that of a plain search engine and how to compare different clustering engines, including an experimental study of the subtopic  ...  ACKNOWLEDGMENTS We are very grateful to three anonymous reviewers for their constructive suggestions and comments.  ...

2013 2013 35th International Conference on Software Engineering (ICSE)  
We evaluated Refoqus empirically against four baseline approaches that are used in natural language document retrieval.  ...  Refoqus outperformed the baselines and its recommendations lead to query performance improvement or preservation in 84% of the cases (in average).  ...  Such approaches are designed to work for natural language documents as they rely on word relationships that exist in natural language.  ...

Essie: A Concept-based Search Engine for Structured Biomedical Text

N. C. Ide, R. F. Loane, D. Demner-Fushman
2007 JAMIA Journal of the American Medical Informatics Association  
Essie's design is motivated by an observation that query terms are often conceptually related to terms in a document, without actually occurring in the document text.  ...  Essie shows that a judicious combination of exploiting document structure, phrase searching, and concept based query expansion is a useful approach for information retrieval in the biomedical domain.  ...  Background The Essie search engine was originally developed in 2000 at the National Library of Medicine to support ClinicalTrials.gov, 5, 6 an online registry of clinical research studies.  ...
