HPSG and TAG

Through this exercise we attempt to gain further insights into the nature of the two theories and to identify correlating concepts. While HPSG has a more elaborated lexicalized and principle-based theory of functor argument structures, TAG provides the means to represent lexical-based structural information more explicitly and to factor out recursion. Our objectives are met by giving clear and simple definitions for projecting structure from the lexicon, for determining "maximal" projections, and for identifying potential auxiliary trees and foot nodes. 1 Introduction Head Driven Phrase Structure Grammar (HPSG) and Tree Adjoining Grammar (TAG) are two frameworks which so far have been largely pursued in parallel, taking little or no account of each other. In this paper we will describe an algorithm which will allow to compi...

The approach is illustrated with examples from English, German and French where the source and the target language sentences show noteworthy differences in linguistic analyses.

The description also includes some characteristics of the grammar formalism and of the various processing components corresponding to different descriptive layers in the grammar. 1 General Characteristics The DISCO grammar is a German grammar whose syntactic part was developed by K. Netter (with support by J. Nerbonne) and which has an integrated semantic representation developed by J. Nerbonne and W. Kasper [Ner92], [Kas93]. The style of the grammar follows very much the spirit of Head Driven Phrase Structure Grammar (HPSG) [PS87], [PS93]. However, it also incorporates insights from other grammar frameworks (e.g., categorial grammar) and extensions to the theory which are not yet part of standard HPSG. The grammar is implemented in a formalism called Type Description Language (TDL) which was developed by H.-U. Krieger and U. Schafer [SK92]. The grammar provides interfaces to a morpho...

This saves on the preliminary basic research, always necessary to establish the fundamental practicability and feasibility of a new formalism.

MIETTA facilitates multilingual information access in a number of languages (English, Finnish, French, German, Italian) to the tourist information (web documents and database information) provided by three different geographical regions: the German federal state of Saarland, the Finnish region around Turku and the Italian City of Rome.

MIETTA --- a framework for uniform and multilingual access to structured database and Web information

The design of the search engine is based on a new crosslingual framework. The framework integrates a crosslingual retrieval strategy with a strategy using natural language techniques: information extraction and multilingual generation. The combination of information extraction and multilingual generation enables on the one hand, multilingual presentation of the database content, and on the other hand, free text crosslingual information retrieval of the structured data entries. We will demonstrate that the new framework is useful for domain specific and multilingual applications.

The tsnlp (Test Suites for Natural Language Processing) project 1 has investigated various aspects of the construction, maintenance and application of systematic test suites as diagnostic and evaluation tools for NLP applications. The paper summarizes the motivation and main results of tsnlp: besides the solid methodological foundation of the project, tsnlp has produced substantial (i.e. larger than any existing general test suites) multipurpose and multiuser test suites for three European languages together with a set of specialized tools that facilitate the construction, extension, maintenance, retrieval, and customization of the test data. The publicly available results of tsnlp represent a valuable linguistic resource that has the potential of providing a widespread pre-standard diagnostic and evaluation tool for both developers and users of NLP applications.

MIETTA is designed to enable users to search and retrieve information on the regions covered in their own language preferably. In order to facilitate the user with such functionality, the system includes document translation, cross-language query translation, multilingual generation from information extraction templates and document classification. In addition, query expansion is offered to identify proper query translation and enable template matching for information extraction purposes.

It was prepared at the request of the European Commission DG XIII by an ad hoc study group, and is now being made available in the form in which it was submitted to the Commission. However, the report is not an official European Commission document, and does not reflect European Commission policy, official or otherwise. After a discussion of terminology, the report focusses on combining user-centred and technology-centred assessment, and on how meaningful comparisons can be made of a variety of systems performing different tasks for different domains. The report outlines the kind of infra-structure that might be required to support comparative assessment and evaluation of heterogenous projects, and also the results of a questionnaire concerning different approaches to evaluation.
