    abstract     = "We describe MuZeeker, a search engine with domain knowledge based on Wikipedia. MuZeeker enables the user to refine a search in multiple steps by means of category selection. In the present version we focus on multimedia search related to music and we present two prototype search applications (web-based and mobile). A category based filtering approach enables the user to refine a search through relevance feedback by category selection instead of typing additional text, which was found to be an advantage in the mobile MuZeeker application. We report from a usability evaluation using the think aloud protocol, in which N=10 participants performed tasks using respectively MuZeeker and a customized Google search engine. The experiment gave initial indications that participants were capable of solving tasks slightly better using MuZeeker, while the {''}inexperienced{''} MuZeeker users performed slightly slower than experienced Google users. 75\% of the participants reported a subjective preference for MuZeeker."
