Knowledge-based and vertical-driven information retrieval
The paper introduces the architecture and functionality of the knowledge-based information retrieval technology developed at Vertical Search Works. A large-scale language-independent ontology is used during indexing, query analysis, and document retrieval as part of a web-scale vertical search engine. Three specific areas are examined: the knowledge resource, its visualization and editing toolb...
متن کاملOntology-driven Information Retrieval in FF-Poirot
This paper proposes a new approach for supporting domain information retrieval and information extraction on the web, using an original query expansion technique supported by an ad-hoc ontology focused on a specific domain of interest. The system has been built and tested in the framework of the FF-Poirot project, for supporting fine-grain retrieval from the Internet aiming at detecting financi...
متن کاملResearch on Ontology-Driven Information Retrieval
An increasing number of recent information retrieval systems make use of ontologies to help the users clarify their information needs and come up with semantic representations of documents. A particular concern here is the integration of these semantic approaches with traditional search technology. The research presented in this paper examines how ontologies can be efficiently applied to large-...
متن کاملData-driven information retrieval in heterogeneous collections of transcriptomics data links SIM2s to malignant pleural mesothelioma
MOTIVATION Genome-wide measurement of transcript levels is an ubiquitous tool in biomedical research. As experimental data continues to be deposited in public databases, it is becoming important to develop search engines that enable the retrieval of relevant studies given a query study. While retrieval systems based on meta-data already exist, data-driven approaches that retrieve studies based ...
