The subcategories may consist not only of named classes but also of compound class expressions. We define the notion of focused categorization power of a given ontology, with respect to a focus class and a concept expression language, as the (estimated) weighted count of the categories that can be built from the ontology\u2019s signature, conform to the language, and are subsumed by the focus class. For the sake of tractable initial experiments we then formulate a restricted concept expression language based on existential restrictions, and heuristically map it to syntactic patterns over ontology axioms (so-called FCE patterns). The characteristics of the chosen concept expression language and associated FCE patterns are investigated using three different empirical sources derived from ontology collections: first, the concept expression pattern frequency in class definitions; second, the occurrence of FCE patterns in the Tbox of ontologies; and last, for class expressions generated from the Tbox of ontologies (through the FCE patterns); their \u2018meaningfulness\u2019 was assessed by different groups of users, yielding a \u2018quality ordering\u2019 of the concept expression patterns. The complementary analyses are then compared and summarized. To allow for further experimentation, a web-based prototype was also implemented, which covers the whole process of ontology reuse from keyword-based ontology search through the FCP computation to the selection of ontologies and their enrichment with new concepts built from compound expressions.<\/jats:p>","DOI":"10.3233\/sw-233401","type":"journal-article","created":{"date-parts":[[2023,8,4]],"date-time":"2023-08-04T12:46:09Z","timestamp":1691153169000},"page":"1209-1253","source":"Crossref","is-referenced-by-count":0,"title":["Focused categorization power of ontologies: General framework and study on simple existential concept expressions"],"prefix":"10.1177","volume":"14","author":[{"given":"Vojt\u011bch","family":"Sv\u00e1tek","sequence":"first","affiliation":[{"name":"Department of Information and Knowledge Engineering, Prague University of Economics and Business, N\u00e1m.
