Unknown words are a major issue for large-scale grammars of natural language. We propose a machine learning based al- gorithm for acquiring lexical entries for all forms in the paradigm of a given un- known word. The main advantages of our method are the usage of word paradigms to obtain valuable morphological knowl- edge, the consideration of different con- texts which the unknown word and all members of its paradigm occur in and the employment of a full-blown syntactic parser and the grammar we want to im- prove to analyse these contexts and pro- vide elaborate syntactic constraints. We test our algorithm on a large-scale gram- mar of Dutch and show that its application leads to an improved parsing accuracy.
