Development of semantic search technologies
Together with scientists of the Technical University Dresden, Dresden-based Transinsight GmbH and BASF SE, Ludwigshafen, scientists of ZEBET are developing the world’s first knowledge-based search engine for alternative methods to animal experiments with support from the Federal Ministry of Research. In April 2008 the beta version of the semantic search engine “Go3R”, which is available free of charge to internet users, went live under www.Go3R.org.
Special feature of the search engine Go3R
The search engine Go3R makes proposals in respect of a certain search term with which the search can be further refined. If a user is, for instance, looking for publications on “eye irritation” Go3R offers the following result categories:
If the user decides, for instance, in favour of the category “Toxicity Testing Strategy, 3Rs” and restricts his search by clicking on the sub category, “In Vitro Test Battery”, he can restrict a large amount of search results with a few clicks to the most relevant aspects using Go3R.
Benefits of the semantic search engine Go3R
Unlike the usual search engines, Go3R identifies, as a semantic search engine, the relationships between the terms and establishes a link to other important term categories. In these categories the searcher can then continue to search in a selective manner. In addition, the search engine also works with synonyms and natural language. For successful searching it is, therefore, no longer necessary to enter the precise keyword. If a user looks for “eye irritation”, the engine searches automatically for “eye tolerance”, too. The search results using Go3R are hence more comprehensive than the results of conventional search engines.
