1 Vorlesung Grammatikformalismen Hans Uszkoreit Kategorialgrammatik und Kategoriale Unifikationsgrammatik

2 Vorlesung Grammatikformalismen Hans Uszkoreit Die Wurzeln Kategorialgrammatik: Ajdukiewicz 1934 Cresswell, Montague, Lambek, Bach,... Neuere Ansätze: Steedman, Moortgat, Hepple, Morrill,... Kategoriale Unifikationsgrammatik: Uszkoreit; Zeevat, Klein & Calder; Karttunen; Bouma,...

3 Vorlesung Grammatikformalismen Hans Uszkoreit Kategorien Mindestens zwei Basiskategorien: N und S Mindestens ein Funktor-Markierer: / meist auch \ Potentiell unendlich viele abgeleitete Kategorien: wenn und Kategorien sind, dann ist auch eine Kategorie z.B. S/N nicht alle abgeleiteten Kategorien sind linguistische Kategorien z.B. (S/S)/(N/N)
