A survey of automatic query expansion in information retrieval
C Carpineto, G Romano - Acm Computing Surveys (CSUR), 2012 - dl.acm.org
The relative ineffectiveness of information retrieval systems is largely caused by the
inaccuracy with which a query formed by a few keywords models the actual user information …

Predicting the effectiveness of queries and retrieval systems
C Hauff - 2010 - research.utwente.nl
In this thesis we consider users' attempts to express their information needs through queries,
or search requests and try to predict whether those requests will be of high or low quality …

An alternative approach to natural language query expansion in search engines: Text analysis of non-topical terms in Web documents
R Fattahi, CS Wilson, F Cole - Information Processing & Management, 2008 - Elsevier
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). NTTs …
