In this paper we introduce a new “scoring” description logic s-EL(D) with concept instance ordering and top-k restriction queries. This enables to create ontologies describing user preferences (ordering of concept instances) and to describe concepts consisting of top-k instances according to this ordering. We construct algorithm for instance problem in s-EL(D). The main application is an extension of web modeling languages to model user preferences and top-k in web services and web search.
