Supervised query modeling using Wikipedia

14/07/2010 Conference Papers Publications No Comments

In a web retrieval setting, there is a clear need for precision enhancing methods. For example, the query “the secret garden” (a novel that has been adapted into movies and musicals) is a query that is easily led astray because of the generality of the individual query terms. While some…

Entity Search: Building Bridges between Two Worlds

20/04/2010 Publications Workshop Papers No Comments

We have come to depend on technological resources to create order and find meaning in the ever-growing amount of online data. One frequently recurring type of query in web search are queries containing named entities (persons, organizations, locations, etc.): we organize our environments around entities that are meaningful to us.…

Learning Semantic Query Suggestions

25/10/2009 Conference Papers Publications No Comments

An important application of semantic web technology is recognizing human-defined concepts in text. Query transformation is a strategy often used in search engines to derive queries that are able to return more useful search results than the original query and most popular search engines provide facilities that let users complete,…

Investigating the Semantic Gap through Query Log Analysis

25/10/2009 Conference Papers Publications No Comments

Significant efforts have focused in the past years on bringing large amounts of metadata online and the success of these efforts can be seen by the impressive number of web sites exposing data in RDFa or RDF/XML. However, little is known about the extent to which this data fits the…

A Semantic Perspective on Query Log Analysis

17/09/2009 Publications Unrefereed No Comments

We present our views on the CLEF log file analysis task. We argue for a task definition that focuses on the semantic enrichment of query logs. In addition, we discuss how additional information about the context in which queries are being made could further our understanding of users’ information seeking…

An evaluation of entity and frequency based query completion methods

16/07/2009 Conference Papers Publications No Comments

From the days of boolean search on library catalogues, users have reformulated their queries after an inspection of initial search results. Traditional information retrieval studies this in frameworks such as query expansion, relevance feedback, interactive retrieval, etc. These methods mostly exploit document contents because that is typically all information that…

Investigating the Demand Side of Semantic Search through Query Log Analysis

17/04/2009 Publications Workshop Papers No Comments

Semantic search is by its broadest definition a collection of approaches that aim at matching the Web’s content with the information need of Web users at a semantic level. Most of the work in this area has focused on the supply-side of semantic search, in particular elevating Web content to…

Concept models for domain-specific search

16/02/2009 Conference Papers Publications No Comments

We describe our participation in the 2008 CLEF Domain-specific track. We evaluate blind relevance feedback models and concept models on the CLEF domain-specific test collection. Applying relevance modeling techniques is found to have a positive effect on the 2008 topic set, in terms of mean average precision and precision@10. Applying…

The University of Amsterdam at the CLEF 2008 Domain Speciﬁc Track – Parsimonious Relevance and Concept Models

16/09/2008 Publications Unrefereed No Comments

We describe our participation in the CLEF 2008 Domain Specific track. The research questions we address are threefold: (i) what are the effects of estimating and applying relevance models to the domain specific collection used at CLEF 2008, (ii) what are the results of parsimonizing these relevance models, and (iii)…

Towards a combined model for search and navigation of annotated documents

16/07/2008 Conference Papers Publications No Comments

Documents whose textual content is complemented with annotations of one kind or another are ubiquitous. Examples include biomedical documents (annotated with MeSH terms) and news articles (annotated with IPTC terms). Such annotations—or concepts—have typically been used for query expansion, to suggest alternative or related query formulations, and to facilitate browsing…
