Description	We consider querying containing several vague concepts of user’s preferences, which is quite typical in semantic web. These particular preferences need to be combined to get an overall ordering of results. We propose ELdescription logic allowing existential restrictions, crisp roles, fuzzy concepts and fuzzy combining functions. This has same semantics as a variant of generalized annotated programs and an extension of description logic programs with fuzzy aggregation. We discuss problems of consistency, subsumption and the instance problem. We show some results on polynomial complexity of this problem.

(en) Uvažujeme dotazování obsahující několik vágních pojmů s uživatelovy preferencemi (typické pro semantický web). Tyto jednotlivé preference musí být kombinovány abychom obdrželi celkové uspořádáí výsledků. Navrhujeme EL deskripční logiku která povoluje existenční restrikci, ostré role a fuzzy pojmy a fuzzy kombinační funkce. Tato má stejnou semantiku jako variant anotovaných programů a rozšíření deskripčních logických programů s fuzzy agregací. Diskutujeme problém konzistence, subsumpce a instancí. Ukazujeme několik výsledků o polynomiální složitosti těchto problémů. (cs)
