The research performed in the DeepThought project aims at demonstrating the potential of deep linguistic processing if combined with shallow methods for robustness. Classical information retrieval is extended by high precision concept indexing and relation detection. On the basis of this approach, the feasibility of three ambitious applications will be demonstrated, namely: precise information extraction for business intelligence; email response management for customer relationship management; creativity support for document production and collective brainstorming. Common to these applications, and the basis for their development is the XML-based, RMRS-enabled core architecture framework that will be described in detail in this paper. The framework is not limited to the applications envisaged in the DeepThought project, but can also be employed e.g. to generate and make use of XML standoff annotation of documents and linguistic corpora, and in general for a wide range of NLP-based applications and research purposes.
We present a detailed study of chemical freeze-out in nucleus-nucleus collisions at beam energies of 11.6, 30, 40, 80 and 158A GeV. By analyzing hadronic multiplicities within the statistical hadronization approach, we have studied the chemical equilibration of the system as a function of center of mass energy and of the parameters of the source. Additionally, we have tested and compared different versions of the statistical model, with special emphasis on possible explanations of the observed strangeness hadronic phase space under-saturation.
During the past fifty years sign languages have been recognised as genuine languages with their own syntax and distinctive phonology. In the case of sign languages, phonetic description characterises the manual and non-manual aspects of signing. The latter relate to facial expression and upper torso position. In the case of manual components these characterise hand shape, orientation and position, and hand/arm movement in three dimensional space around the signer's body. These phonetic charcaterisations can be notated as HamNoSys descriptions of signs which has an executable interpretation to drive an avatar.
The HPSG sign language generation component of a text to sign language system prototype is described. The assimilation of SL morphological features to generate signs which respect positional agreement in signing space are emphasised.
Background The detection of the new Coranavirus (CoV) causing agent of the severe acute respiratory syndrome (SARS) for diagnostic purposes is still a critical step in prevention of secondary hospital infections. In this respect the PCR for SARS diagnostic is the fastest and most sensitive method and was published very early after the description of the new pathogen by different groups. To evaluate the quality and sensitivity of the SARS PCR performed in diagnostic laboratories all over the world an external quality assurance (EQA) for SARS PCR was initiated by the WHO, the European Network for Diagnostics of "Imported" Viral Diseases (ENIVD) and the Robert Koch-Institut. Methods Therefore 10 samples of inactivated SARS CoV strains isolated in Frankfurt and Hong Kong in different dilutions and negative controls were prepared. The freeze dried samples were send by mail to 62 different laboratories, in 37 countries in Europe and Israel (35), Asia (11), The Americas (11), Australia and New Zealand (4) and Africa (1). The results were returned by email or fax 1 week (13), 2 weeks (14), 3 weeks (6) and later (29) after receiving the material which does not mimic at all the possible speed of this fast method. But this was not considered in the evaluation of these first SARS EQA. Results 44 laboratories showed good or excellent results (26 = 100%, 18 = 90%) and even the 14 laboratories which archived only 80% (10) or 70% (4) correct results are mostly lacking sensitivity. The results of the other 4 laboratories show basic problems in regard to sensitivity, specificity and consistency of results and must be overcome as soon as possible. 4 laboratories seem to have problems with the specificity finding a positive signal in negative samples. The different methods used for preparation of the SARS CoV genome and diagnostic PCR test procedure used by the participating laboratories will be discussed in more detail in the presentation. Conclusion However, in contrast to previous EQAs for Ebola, Lassa and Orthopoxviruses the quality of PCR results was rather good which might be caused by the early publication and distribution of well developed PCR methods. An EQA for evaluation of SARS specific serology is still ongoing, first results will be available beginning of April 2004.
Background and Aim: In Germany, the discharge medication is usually reported to the general practitioner (GP) by an inital short report (SR) /notification (handed over to the patient) and later by a more detailed discharge letter (DL) of the hospital.
Material and Method: We asked N=536 GPs (from Frankfurt/Main and Luebeck) after the typical report format of their patients discharge medication by the local hospitals. The questionnaire asked for 26 items covering (1) the designation of the medication (brand name, generic name) in SR and DL, (2) further specifications e.g. possibilities of generic substitution or supervision of sensible medications, (3) reasons why GPs do not follow the hospitals recommendations and (4) possibilities for an improvement in the medication-related communication between GP and hospitals.
Results: 39% GPs responded sufficiently to the questionnaire. The majority of the GPs (82%) quoted that in the SR only brand names are given (often or ever) and neither the generic name or any further information on generic substitution is available (seldom or never). 65% of the responders quoted that even in the DL only brand names are given. Only 41% of the responders quoted that further treatment relevant specifications are given (often or ever). 95% responded that new medications or change of custom medication is seldom or never explained in the DL and GP were not explicitly informed about relevant medication changes. 58% of the responders quoted economic reasons for re-adjustment of the discharge medication e.g. by generic substitution. The majority of responders (83%) are favouring (useful or very useful) a pre-discharge information (e.g. via fax) about the medication and 54% a hot-line to some relevant person in the hospital when treatment problems emerge. 67% of the responders quoted in favour of regular meetings between GPs and hospital doctors regarding actual pharmacotherapy.
Conclusion: In conclusion, our survey pointed to marked deficiencies in reporting the discharge medication to GPs.

The Russian data presented in Perlmutter and Moore (2002) seem to call into question the standard analysis of raising within Head-driven Phrase Structure Grammar (HPSG): In Russian, the case marking of the raising target and raising pivot does not seem to be shared. In this paper, we show that the phenomena described by Perlmutter and Moore can receive another analysis, fully compatible with HPSG's theory of raising. We argue in addition that our account leads to a slightly simpler model of the Russian data than Perlmutter and Moore's. Crucially, our analysis is only available if we avail ourselves of a rich network of language-specific constructional schemata, a stance recently advocated within HPSG, following the lead of Construction Grammar.
Vor gut einem Jahr ist im Archiv für die civilistische Praxis ein Aufsatz erschienen, in welchem ich mich mit den Perspektiven des Verbrauchervertragsrechts nach der Schuldrechtsreform auseinandergesetzt habe. Der leicht provozierende Unterton der dort vorgetragenen Kritik hat nun nicht nur – wie beabsichtigt – den einen oder anderen Leser zum Lachen verführt, sondern offensichtlich auch Irritationen bezüglich der Richtung hervorgerufen, in die der Verbraucherschutzzug in Zukunft fahren soll: zurück in die Siebziger Jahre und – nach erneutem Schlagen vergangener Schlachten – ins bürgerliche Formalrecht des 19. Jahrhundert? Oder was soll mit dem Stichwort "Prozedurales Verbrauchervertragsrecht" gemeint sein? Ich möchte an dieser Stelle einen Präzisierungsversuch unternehmen.
This paper discusses a special kind of syntax-semantics mismatch: a noun with a relative clause is interpreted as if it were a complement clause. An analysis in terms of Lexical Resource Semantics is developed which provides a uniform account for ''normal'' relative clauses and for the discussed type of relative clause.
The volume is a collection of papers given at the conference “sub8 -- Sinn und Bedeutung”, the eighth annual conference of the Gesellschaft für Semantik, held at the Johann-Wolfgang-Goethe-Universität, Frankfurt (Germany) in September 2003. During this conference, experts presented and discussed various aspects of semantics. The very different topics included in this book provide insight into fields of ongoing Semantics research.
