Using Noun Phrases for Local Analysis in Automatic Query Expansion

João Marcelo Azevedo Arcoverde, Maria das Graças Volpe Nunes, Wendel Scardua
2006 Conference and Labs of the Evaluation Forum  
It is well known the power of noun phrases in the role of descriptors with high discriminatory and informative potential.  ...  This work presents a local analysis technique to automatic query expansion through the use of noun phrases extracted from the pseudo-relevant set, for the Ad-Hoc, monolingual (Portuguese) track.  ...  Then it is possible to rank the set of noun phrases from the pseudorelevant documents according to its weight, in descendent order, and pick up the first top n noun phrases.  ...

Keyphrase extraction-based query expansion in digital libraries

Min Song, Il Yeol Song, Robert B. Allen, Zoran Obradovic
2006 Proceedings of the 6th ACM/IEEE-CS joint conference on Digital libraries - JCDL '06  
In this paper, we present a novel unsupervised query expansion technique that utilizes keyphrases and POS phrase categorization.  ...  In pseudo-relevance feedback, the two key factors affecting the retrieval performance most are the source from which expansion terms are generated and the method of ranking those expansion terms.  ...  [13] used noun phrases for query expansion. Specifically, four types of noun phrases were identified: proper names, dictionary phrases, simple phrases, and complex phrases.  ...

2006 Information Processing & Management  
The TREC results show that one of the methods is an effective means of interactive query expansion and yields significant performance improvements.  ...  The second method consists of showing to the user a list of noun phrases extracted from the initial document set. Both methods then expand the query based on the user feedback.  ...  Further interactive experiments are needed to evaluate how helpful are noun phrases to users in selecting potential expansion terms.  ...
