It is well known that the meaning of a verb-based construction depends not only on the lexical meaning of the verb but also on its specific syntagmatic environment. Lexical meaning interacts with constructional meaning in intricate ways and this interaction is crucial for theories of argument linking and the syntax-semantics interface. These insights have(More)
The proper interpretation of prepositions is an important issue for automatic natural language understanding. We present an approach towards PP interpretation as part of a natural language understanding system which has been successfully employed in various NLP tasks for information retrieval and question answering. Our approach is based on the so-called(More)

In the so-called information society with its strong tendency towards individualization, it becomes more and more important to have all sorts of textual information available in a simple and easy to understand language. We present an approach that allows to automatically rate the readability of German texts and also provides suggestions how to make a given(More)
Different types of linguistic classification, ranging from simple inheritance hierarchies to systemic networks, are classified algebraically and order-theoretically. To this end, classifications are reformulated as observational theories. Classifications that do not involve disjunction correspond to Horn theories, whose generic universe ordered by(More)
We describe the treatment of verbs with prepositional complements in HaGenLex, a semantically based computer lexicon for German. Prepositional verbs such as bestehen auf (‘insist on’) subcategorize for a prepositional phrase where the preposition usually has no independent meaning of its own. The lexical semantic information in HaGenLex is specified by(More)
