This paper presents an approach for the automatic acquisition of qualia structures for nouns from the Web and thus opens the possibility to explore the impact of qualia structures for natural language processing at a larger scale. The approach builds on earlier work based on the idea of matching specific lexico-syntactic patterns conveying a certain semantic relation on the World Wide Web using standard search engines. In our approach, the qualia elements are actually ranked for each qualia role with respect to some measure. . | Automatic Acquisition of Ranked Qualia Structures from the Web1 Philipp Cimiano Inst.

The approach builds on earlier work based on the idea of matching specific lexico-syntactic patterns conveying a certain semantic relation on the World Wide Web using standard search engines. In our approach the qualia elements are actually ranked for each qualia role with respect to some measure. The specific contribution of the paper lies in the extensive analysis and quantitative comparison of different measures for ranking the qualia elements. Further for the first time we present a quantitative evaluation of such an approach for learning qualia structures with respect to a handcrafted gold standard. 1 Introduction Qualia structures have been originally introduced by Pustejovsky 1991 and are used for a variety of purposes in natural language processing NLP such as for the analysis of compounds Johnston and Busa 1996 as well as co-composition and coercion Pustejovsky 1991 but also for bridging reference resolution Bos et al. 1995 . Further it has also 1The work reported in this paper has been supported by the X-Media project funded by the European Commission under EC grant number IST-FP6-026978 as well by the SmartWeb project funded by the German Ministry of Research. Thanks to all our colleagues for helping to evaluate the approach. 888 been argued that qualia structures and lexical semantic relations in general have applications in information retrieval Voorhees 1994 Pustejovsky et al. 1993 . One major bottleneck however is that currently .
