{"type":"ScholarlyArticle","title":"X2MORF: A Morphological Component Based on Augmented Two-Level Morphology","authors":[{"name":"Harald Trost","slug":"harald-trost","given":"Harald","family":"Trost","affiliation":""}],"abstract":"X2MORF1 is a language independent morphological component for the recognition and generation of word forms based on a lexicon of morphs. The approach is based on two-level morphology. Extensions are motivated by linguistic data which call into question an underlying assumption of standard two-level morphology namely the independence of morphophonology and morphology as exemplified by two-level rules and continuation classes. Accordingly, I propose a model which allows for interaction between these two parts. Instead of using continuation classes, word formation is described in a feature-based unification grammar. Twolevel rules are provided with a morphological context in the form of feature structures. Information contained in the lexicon and the word formation grammar guides the application of two-level rules by matching the morphological context against the morphs. I present an efficient implementation of that model where rules are compiled into automata (as in the standard model) and where processing of the feature-based grammar is enhanced using an automaton derived from that grammar as a filter.","doi":null,"url":"https://ijcai.org/proceedings/1991/151","pdf":"https://ijcai.org/proceedings/1991/0151.pdf","markdown":"https://ijcai.org/proceedings/1991/151.md","bibtex":"https://ijcai.org/proceedings/1991/bibtex/151","volume":{"slug":"1991","title":"Proceedings of the Twelfth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1991","url":"https://ijcai.org/proceedings/1991/","year":1991,"location":"Sydney, New South Wales, Australia","dates":"24-30 August 1991","editors":"John Mylopoulos and Ray Reiter","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Natural Language","track":"Natural Language","number":151,"pages":{"first":1024,"last":1029},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
