Mobile qualified electronic signatures for secure mobile brokerage (2004)

Heiko Roßnagel

Despite a legal framework being in place for several years, the market share of qualified electronic signatures is disappointingly low. Mobile Signatures provide a new and promising opportunity for the deployment of an infrastructure for qualified electronic signatures. We that SIM-based signatures are the most secure and convenient solution. However, using the SIM-card as a secure signature creation device (SSCD) raises new challenges, because it would contain the user’s private key as well as the subscriber identification. Combining both functions in one card raises the question who will have the control over the keys and certificates. We propose a protocol called Certification on Demand (COD) that separates certification services from subscriber identification information and allows consumers to choose their appropriate certification services and service providers based on their needs. This infrastructure could be used to enable secure mobile brokerage services that can ommit the necessity of TAN lists and therefore allow a better integration of information and transaction services.

Implementing the Syntax of Japanese Numeral Classifiers (2004)

Emily M. Bender Melanie Siegel

While the sortal constraints associated with Japanese numeral classifiers are wellstudied, less attention has been paid to the details of their syntax. We describe an analysis implemented within a broadcoverage HPSG that handles an intricate set of numeral classifier construction types and compositionally relates each to an appropriate semantic representation, using Minimal Recursion Semantics.

Video goes online - Szenarien für eine Lehre der Zukunft (2004)

Werner Große

Vortrag gehalten bei der 34. Jahrestagung des Fachverbandes Medien und Technik im Bildungsbereich (MTB) am 25. September 2003 in Göttingen: "Sehr verehrte Damen und Herren, „Video goes online“ ist ganz allgemein etwas, das auch ohne unser Zutun passieren wird. Wie weit und wie schnell es in die praktische Lehre eindringen wird, wage ich angesichts des heutigen Einsatzes sehr viel älterer Medientechnologien im deutschen Hochschulunterricht nicht abzuschätzen. Damit wäre ich eigentlich am Ende meines Vortrags. Dennoch möchte ich sie mit einigen Gedanken konfrontieren, die um die Frage kreisen: Gibt es für einen künftigen, Internet basierten Einsatz hinreichend geeignete Videos und wie müssen die beschaffen sein?.."

The DeepThought Core Architecture Framework (2004)

Ulrich Callmeier Andreas Eisele Ulrich Schäfer Melanie Siegel

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.

Head-Initial Constructions in Japanese (2004)

Melanie Siegel Emily M. Bender

Japanese is often taken to be strictly head-final in its syntax. In our work on a broad-coverage, precision implemented HPSG for Japanese, we have found that while this is generally true, there are nonetheless a few minor exceptions to the broad trend. In this paper, we describe the grammar engineering project, present the exceptions we have found, and conclude that this kind of phenomenon motivates on the one hand the HPSG type hierarchical approach which allows for the statement of both broad generalizations and exceptions to those generalizations and on the other hand the usefulness of grammar engineering as a means of testing linguistic hypotheses.

Hybrid Robust Deep and Shallow Semantic Processing for Creativity Support in Document Production (2004)

Hans Uszkoreit Ulrich Callmeier Andreas Eisele Ulrich Schäfer Melanie Siegel

The research performed in the DeepThought project (http://www.project-deepthought.net) aims at demonstrating the potential of deep linguistic processing if added to existing shallow methods that ensure robustness. Classical information retrieval is extended by high precision concept indexing and relation detection. We use this approach to demonstrate the feasibility of three ambitious applications, one of which is a tool for creativity support in document production and collective brainstorming. This application is described in detail in this paper. Common to all three applications, and the basis for their development is a platform for integrated linguistic processing. This platform is based on a generic software architecture that combines multiple NLP components and on robust minimal recursive semantics (RMRS) as a uniform representation language.
