Semantic query expansion is the process of supplementing a user query with additional terms that interpret and extend the user's information needs. This work presents the results of an empirical study that investigates user preferences for different designs of user interfaces that provide semantic query expansion for data search from geo-data repositories. The study assesses further whether it is possible to map qualitative gradations of semantic relatedness between geographic key terms to ranges of numerical similarity values.
