Query Expansion in Folksonomies
2011People share resources in folksonomies and add tags to these resources. There are often only a few tags associated with each resource, which makes the data available in folksonomies extremely sparse. Spareness in folksonomies makes searching resources difficult.

This chapter demonstrates how feature-based models can be extended and used for query expansion using a technique known as latent concept expansion (LCE). The approach has three key benefits, including the ability to go beyond the bag of words assumption, the ability to employ arbitrary features during the query expansion process, and the ability to ...

Query expansion through weighted word Pairs
2014The aim of this paper is to propose a novel query expansion method to improve accuracy of text retrieval systems. Our technique makes use of a minimal explicit relevance feedback to expand an initial query with a structured representation called Weighted Word Pairs.
