Background Because of the increasing number of electronic resources, designing efficient
tools to retrieve and exploit them is a major challenge. Some improvements have been …

A large amount of biomedical and genomic data are currently available on the Internet.
However, data are distributed into heterogeneous biological information sources, with little …

Ontologies have proven to be useful in the area of Information Retrieval and the biomedical
informatics community has acknowledged, in recent years, their utility. However, building …

Ontologies are frequently used in information retrieval being their main applications the
expansion of queries, semantic indexing of documents and the organization of search …

The volume of publicly available genomic scale data is increasing. Genomic datasets in
public repositories are annotated with free-text fields describing the pathological state of the …

The huge number of available documents on the Web makes finding relevant ones a
challenging task. The quality of results that traditional full-text search engines provide is still …

OntoSearch, a full-text search engine that exploits ontological knowledge for document
retrieval, is presented in this paper. Different from other ontology based search engines …

In recent years, technological advances in high-throughput techniques and efficient data
gathering methods, coupled with a world-wide effort in computational biology, have resulted …

The exponential growth of available electronic data is almost useless without efficient tools
to retrieve the right information at the right time. This is especially crucial in the context of …

We define a general framework for ontology-based information retrieval (IR). In our
approach, document and query expansion rely on a base taxonomy that is extracted from a …
