Improving understandability of semantic search explanations
<22> The long-term goal of explanation-aware software design is to provide methods and tools for systematically engineering comprehensibility into software systems. This paper describes how we improved a semantic search engine, RadSem, in this regard. RadSem is based on formal ontologies and designated for different kinds of users. Semantic search results are often hard to understand. An explanation facility for justifying and exploring search results was integrated into RadSem employing the same ontologies used for searching also for explanation generation. We evaluated the comprehensibility of algorithmically selected concept labels with different user groups using word class frequencies for selecting appropriate labels.
