Query Expansion with Freebase

Proceedings of the 2015 International Conference on The Theory of Information Retrieval, 2015
Large knowledge bases are being developed to describe entities, their attributes, and their relationships to other entities. Prior research mostly focuses on the construction of knowledge bases, while how to use them in information retrieval is still an open problem.

Query expansion using associated queries

Proceedings of the twelfth international conference on Information and knowledge management - CIKM '03, 2003
Hundreds of millions of users each day use web search engines to meet their information needs. Advances in web search effectiveness are therefore perhaps the most significant public outcomes of IR research. Query expansion is one such method for improving the effectiveness of ranked retrieval by adding additional terms to a query.

Social semantic query expansion

ACM Transactions on Intelligent Systems and Technology, 2013
Weak semantic techniques rely on the integration of Semantic Web techniques with social annotations and aim to embrace the strengths of both. In this article, we propose a novel weak semantic technique for query expansion. Traditional query expansion techniques are based on the computation of two-dimensional co-occurrence matrices.

On relevance, time and query expansion

Proceedings of the 20th ACM international conference on Information and knowledge management, 2011
We present the results of our exploratory analysis on the relationship that exists between relevance and time. We observe how the amount of documents published in a given interval of time is related to the probability of relevance, and, using the time series analysis, we show the existence of a correlation between time and relevance.

Query expansion based on ontology for Vietnamese query

Proceedings of the 14th International Conference on Information Integration and Web-based Applications & Services, 2012
User's query sometimes does not fully reflect the semantics, so the information retrieval systems return no results as expected results, it is necessary to add semantics to the user's query. The paper represents how to add semantics into a query in Vietnamese language based on Ontology of Object Member Property (OOMP) by improved Similar Noun Phrase ...
