This paper proposes an approach how the search and navigation process can be supported by the usage of lexical knowledge such as WordNet or GermaNet. Those databases contain information about the linguistic relationships between words, e.g. hyponym and hypernym. The approach shows how linguistic relationships can be used to support search and navigation in legal information databases. Analysis of the search term and proposing of related hypernyms and hyponyms in the front-end enables users to expand or refine their search term depending on the selected word in the facet. The drawbacks, limitations and open issues regarding this approach are discussed at the end of this paper.
