In this paper, semantic aspects of P1N1P2 word sequences will be discussed. Based on syntactic analysis of Trawinski (2003), which assumes prepositions heading P1N1P2NP combinations to be able to raise and realize syntactically complements of their arguments, we will investigate whether semantic representation of these expressions can be considered as an instance of the combinatorics semantics. We will investigate three German PPs involving expressions under consideration with respect to two criteria of internal semantic regularity adopted from Sailer (2000) and we will observe that the discussed expressions are not uniform with regard to the semantic properties. While the logical form of some of them can be computed by means of ordinary translations and a set of standard derivational operations, the other require additional handling methods. However, there are approaches available within the HPSG paradigm that are suited to account for these data. Here, we will briefly present the external selection approach of Soehn (2003) and the phrasal lexical entries approach of Sailer (2000) and we will show how they interact with the syntactic approach of Trawinski (2003).
In this paper we outline our corpus-driven approach to detecting, describing and presenting multi- word expressions (MWEs). Our goal is to treat MWEs in a way that gives credit to their flexible nature and their role in language use. The bases of our research are a very large corpus and a Statistical method of collocation analysis. The rich empirical data is interpreted linguistically in a structured way which captures the interrelations, patterns and types of variances of MWEs. Several levels of abstraction build on each other: surface patterns, lexical realizations (LRs), MWEs and MWE patterns. Generalizations are made in a controlled way and in adherence to corpus evidence. The results are published online in a hypertext format.
