Commonality-Based ABox Retrieval
Thomas Mantay · 2000
In commonality-based information retrieval, the commonalities of user-specied examples of desired information is used for information retrieval. As described in previous literature, such a retrieval mechanism can be built using a combination of description logic reasoning services making this retrieval technique an interesting research topic in the eld of description logic applications. However, as will be shown in this article, the existing technique does not always yield a desirable retrieval result. Therefore, we present a theoretical framework useful for commonality-based information retrieval and other description logic applications. Part of this framework is a formal denition of the notion of ABox subsumption using the standard semantics for ABoxes and provide an algorithm for deciding this problem. Based on ABox subsumption, we will present an operation for determining the least common subsuming ABox of a set of ABoxes w.r.t. the expressive description logics AL...
