چکیده

This paper describes the UMass TREC 2005 Robust Track experiments. We focus on approaches that use term proximity and pseudo-relevance feedback using external collections. Our results indicate both approaches are highly effective.

NLPR at TREC 2005: HARD Experiments

1 Overview It is the third time that Chinese Information Processing Group of NLPR takes part in TREC. In the past, we participated in Novelty track and Robust track, in which we had evaluated our two key notions: Window-based Retrieval Algorithm and Result Emerging Strategy [1][2]. This year we focus on investigating the significance of relevance feedback, so HARD track is our best choice. HARD...

Dirichlet Mixtures for Query Estimation in Information Retrieval

Treated as small samples of text, user queries require smoothing to better estimate the probabilities of their true model. Traditional techniques to perform this smoothing include automatic query expansion and local feedback. This paper applies the bioinformatics smoothing technique, Dirichlet mixtures, to the task of query estimation. We discuss Dirichlet mixtures’ relation to relevance models...

Query expansion based on relevance feedback and latent semantic analysis

Web search engines are one of the most popular tools on the Internet which are widely-used by expert and novice users. Constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. Query expansion is a way to reduce this concern and increase user satisfaction. In this paper, a new method of query expa...

UMass Amherst and UT Austin @ the TREC 2009 Relevance Feedback Track

We present a new supervised method for estimating term-based retrieval models and apply it to weight expansion terms from relevance feedback. While previous work on supervised feedback [Cao et al., 2008] demonstrated significantly improved retrieval accuracy over standard unsupervised approaches [Lavrenko and Croft, 2001, Zhai and Lafferty, 2001], feedback terms were assumed to be independent i...

UMass at TREC WEB 2014: Entity Query Feature Expansion using Knowledge Base Links

Entity linking tools predict links between entity mentions in text and knowledge base entries. In this work we leverage the rich semantic knowledge available through these links to understand relevance of documents for a query. We focus on the ad hoc task on the category A subset and demonstrate the benefit of entity-centric approaches even for non-entity queries like “dark chocolate health ben...
