Oktober 2010Dresden, den 11.08.2010ABSTRACTSearching is a fundamental task to support research. Current search engines are keyword-based.Semantic technologies promise a next generation of semantic engines, which will be ableto answer questions. Current approaches either apply natural language processing to unstructuredtext or they assume the existence of structured statements over which they can reason.This work provides a system for combining the classical keyword-based search engines withsemantic annotation. Conventional search results are annotated using a customized annotationalgorithm, which takes the textual properties and requirements such as speed and scalability intoaccount. The biomedical background knowledge consists of the GeneOntology and Medical Sub-ject Headings and other related entities, e.g. proteins/gene names and person names. Togetherthey provide the relevant semantic context for a search engine for the life sciences.
