The present study poses the question on what phonetic and phonological grounds postalveolar fricatives in Polish can be analyzed as retroflex and whether postalveolar fricatives in other Slavic languages are retroflex as well. Velarization and incompatibility with front vowels are introduced as articulatory criteria for retroflexion, based on crosslinguistic data. According to these criteria, Polish and Russian have retroflex fricatives, whereas Bulgarian and Czech do not. In a phonological representation of these Slavic retroflexes, the necessity of perceptual features is shown. Lastly, it is illustrated that palatalization of retroflex fricatives both in Slavic languages and more generally causes a phonetic and phonological change to a non-retroflex sound.
Düsseldorf is the capital of North Rhine-Westphalia, the state with the highest number of inhabitants in Germany. The city has a rich cultural history: The theatre history started in 1485 (the festivities in the context of a princely marriage at Düsseldorf). Theatre historiography marks three great periods for Düsseldorf (Immermann, 1834-1837; Dumont-Lindemann, 1905-1933; Gründgens, 1947-1955). The city has a long history of involvment with film, too. For instance the first German film journal „Der Kinematogaph“ began publishing here in 1907. Düsseldorf became after 1945 a distribution center and served for decades as site of all major German and foreign distributors‘ headquartes. It offers still a lot of cultural events: performing arts in different forms (theatre at the Düsseldorfer Schauspielhaus, musical at the Capitol, opera and ballet at the German Opera Düsseldorf-Duisburg, dance at the Tanzhaus (Dance House) North Rhine-Westphalia, free and independant theatre groups, private theatres, cinema, media, museums, cultural institutions, representing other countries like France, Poland ...
Based on a detailed case study of parallel grammar development distributed across two sites, we review some of the requirements for regression testing in grammar engineering, summarize our approach to systematic competence and performance profiling, and discuss our experience with grammar development for a commercial application. If possible, the workshop presentation will be organized around a software demonstration.
In the last years, much effort went into the design of robust anaphor resolution algorithms. Many algorithms are based on antecedent filtering and preference strategies that are manually designed. Along a different line of research, corpus-based approaches have been investigated that employ machine-learning techniques for deriving strategies automatically. Since the knowledge-engineering effort for designing and optimizing the strategies is reduced, the latter approaches are considered particularly attractive. Since, however, the hand-coding of robust antecedent filtering strategies such as syntactic disjoint reference and agreement in person, number, and gender constitutes a once-for-all effort, the question arises whether at all they should be derived automatically. In this paper, it is investigated what might be gained by combining the best of two worlds: designing the universally valid antecedent filtering strategies manually, in a once-for-all fashion, and deriving the (potentially genre-specific) antecedent selection strategies automatically by applying machine-learning techniques. An anaphor resolution system ROSANA-ML, which follows this paradigm, is designed and implemented. Through a series of formal evaluations, it is shown that, while exhibiting additional advantages, ROSANAML reaches a performance level that compares with the performance of its manually designed ancestor ROSANA.

This article examines the expression of natural gender in Icelandic nouns denoting human beings. Particular attention will be paid to the system's symmetry with regards to nouns denoting women and men. Our society consists more or less exactly of half women and half men. One would therefore assume that systems for terms denoting persons would also be symmetrically organised. Yet this assumption could not be further from the truth, and not just in single isolated cases, but in many languages: I will attempt to show that Icelandic has numerous methods for referring to women, but also many barriers and idiosyncrasies.
