In this note I consider a recent paper which explores the use of factor hierarchies in this connection. In that work it was shown both that cases constrained with the use of a hierarchy may be unconstrained if the hierarchy is flattened, and that cases unconstrained with a hierarchy may be constrained when the hierarchy is flattened. I discuss the nature of factor hierarchies and attempt to explain these results.<\/jats:p>","DOI":"10.3233\/faia230940","type":"book-chapter","created":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T09:35:49Z","timestamp":1702287349000},"source":"Crossref","is-referenced-by-count":1,"title":["A Note on Hierarchical Constraints"],"prefix":"10.3233","author":[{"given":"Trevor","family":"Bench-Capon","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Liverpool, UK"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Legal Knowledge and Information Systems"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA230940","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T09:35:50Z","timestamp":1702287350000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA230940"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,7]]},"ISBN":["9781643684727","9781643684734"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia230940","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,12,7]]}}}
