Corpus based Enrichment of GermaNet Verb Frames

Lexical semantic resources, like WordNet, are often used in real applications of natural language document processing. For example, we integrated GermaNet in our document suite XDOC of processing of German forensic autopsy protocols. In addition to the hypernymy and synonymy relation, we want to adapt GermaNet's verb frames for our analysis. In this paper we outline an approach for the domain related enrichment of GermaNet verb frames by corpus based syntactic and co-occurred data analyses of real documents.

Clever Search: A WordNet Based Wrapper for Internet Search Engines

This paper presents an approach to enhance search engines with information about word senses available in WordNet. The approach exploits information about the conceptual relations within the lexical-semantic net. In the wrapper for search engines presented, WordNet information is used to specify user's request or to classify the results of a publicly available web search engine, like google, yahoo, etc.

Issues in Exploiting GermaNet as a Resource in Real Applications

This paper reports about experiments with GermaNet as a resource within domain specific document analysis. The main question to be answered is: How is the coverage of GermaNet in a specific domain? We report about results of a field test of GermaNet for analyses of autopsy protocols and present a sketch about the integration of GermaNet inside XDOC. Our remarks will contribute to a GermaNet user's wish list.

Transforming and Enriching Documents for the Semantic Web

We suggest to employ techniques from Natural Language Processing (NLP) and Knowledge Representation (KR) to transform existing documents into documents amenable for the Semantic Web. Semantic Web documents have at least part of their semantics and pragmatics marked up explicitly in both a machine processable as well as human readable manner. XML and its related standards (XSLT, RDF, Topic Maps etc.) are the unifying platform for the tools and methodologies developed for different application scenarios.

Context Related Derivation of Word Senses

Real applications of natural language document processing are very often confronted with domain specific lexical gaps during the analysis of documents of a new domain. This paper describes an approach for the derivation of domain specific concepts for the extension of an existing ontology. As resources we need an initial ontology and a partially processed corpus of a domain. We exploit the specific characteristic of the sublanguage in the corpus. Our approach is based on syntactical structures (noun phrases) and compound analyses to extract information required for the extension of GermaNet's lexical resources.

Transforming Business Rules Into Natural Language Text

The aim of the project presented in this paper is to design a system for an NLG architecture, which supports the documentation process of eBusiness models. A major task is to enrich the formal description of an eBusiness model with additional information needed in an NLG task.

An Approach for Resource Sharing in Multilingual NLP

In this paper we describe an approach for the analysis of documents in German and English with a shared pool of resources. For the analysis of German documents we use a document suite, which supports the user in tasks like information retrieval and information extraction. The core of the document suite is based on our tool XDOC. Now we want to exploit these methods for the analysis of English documents as well. For this aim we need a multilingual presentation format of the resources. These resources must be transformed into an unified format, in which we can set additional information about linguistic characteristics of the language depending on the analyzed documents. In this paper we describe our approach for such an exchange model for multilingual resources based on XML.

Exploiting Sublanguage and Domain Characteristics in a Bootstrapping Approach to Lexicon and Ontology Creation

It is very costly to build up lexical resources and domain ontologies. Especially when confronted with a new application domain lexical gaps and a poor coverage of domain concepts are a problem for the successful exploitation of natural language document analysis systems that need and exploit such knowledge sources. In this paper we report about ongoing experiments with `bootstrapping techniques' for lexicon and ontology creation.

An XML based Document Suite

We report about the current state of development of a document suite and its applications. This collection of tools for the flexible and robust processing of documents in German is based on the use of XML as unifying formalism for encoding input and output data as well as process information. It is organized in modules with limited responsibilities that can easily be combined into pipelines to solve complex tasks. Strong emphasis is laid on a number of techniques to deal with lexical and conceptual gaps that are typical when starting a new application.
