AbstractWe present RefRef, a tool for viewing and exploring coreference space, which is publicly available for research purposes. Unlike similar tools currently available whose main goal is to assist the annotation process of coreference links, RefRef is dedicated for viewing and exploring coreference-annotated data, whether manually tagged or automatically resolved. …...

AbstractIn this paper, we propose a formal framework that takes into account the influence of the intended context of use of an NLP system on the procedure and the metrics used to evaluate the system. We introduce in particular the notion of a context-dependent quality model and explain how it …...

AbstractWe present a non-deterministic finite-state transducer that acts as a tokenizer and normalizer for free text that is input to a broad-coverage LFG of German. We compare the basic tokenizer used in an earlier version of the grammar and the more sophisticated tokenizer that we now use. The revised tokenizer …...

AbstractIn this article, we present an experiment that aims to evaluate the feasibility of a superficial morphological analysis, to analyse unknown constructed neologisms. For any morphosyntactic analyser, lexical incompleteness is a real problem. This lack of information is partly due to lexical creativity, and more especially to the productivity of …...

AbstractAs part of a project to construct an interactive program which will encourage children to play with language by building jokes, we have developed a large lexical database, closely based on WordNet. As well as the standard WordNet information about part of speech, synonymy, hyponymy, etc, we have added phonetic …...

AbstractThis paper discusses evaluation methodologies for a particular kind of meaning models known as word-space models, which use distributional information to assemble geometric representations of meaning similarities. Word-space models have received considerable attention in recent years, and have begun to see employment outside the walls of computational linguistics laboratories. However, …...

AbstractThis paper describes the design, collection and current status of the Hans Christian Andersen (HCA) conversation corpus. The corpus consists of five separate corpora and represents transcription and annotation of some 57 hours of English spoken and deictic gesture user-system interaction recorded mainly with children 2002-2005. The corpora were collected …...

AbstractThe performance of three different taggers (Treetagger, Freeling and GRAMPAL) is evaluated on three different languages, i.e. English, Italian and Spanish. The materials are transcripts from the European Parliament Interpreting Corpus (EPIC), a corpus of original (source) and simultaneously interpreted (target) speeches. Owing to the oral nature of our materials …...

AbstractWe describe a case study in the reuse and transfer of tools in language resource development, from a corpus of spoken Dutch to a corpus of written Dutch. Once tools for a particular language have been developed, it is logical, but not trivial to reuse them for other types or …...

AbstractWe introduce MaltParser, a data-driven parser generator for dependency parsing. Given a treebank in dependency format, MaltParser can be used to induce a parser for the language of the treebank. MaltParser supports several parsing algorithms and learning algorithms, and allows user-defined feature models, consisting of arbitrary combinations of lexical features, …...

AbstractThis paper presents an overview of the work in progress at the W3C to produce a conversion of WordNet to the RDF/OWL representation language in use in the Semantic Web community. Such a standard representation is useful to provide application developers a high-quality resource and to promote interoperability. Important requirements …...

AbstractAt the MPI for Psycholinguistics a large archive with language resources has been created with contributions from many different individual researchers and research projects. All of these resources, in particular annotated media streams and multimedia lexica, are accessible via the web and can be utilized with the help of web-based …...

AbstractUtilization of computer tools in linguistic research has gained importance with the maturation of media frameworks for the handling of digital audio and video. The increased use of these tools in gesture, sign language and multimodal interaction studies has led to stronger requirements on the flexibility, the efficiency and in …...

AbstractWe describe the implementation of a FrameNet-based semantic role labeling system for Swedish text. To train the system, we used a semantically annotated corpus that was produced by projection across parallel corpora. As part of the system, we developed two frame element bracketing algorithms that are suitable when no robust …...

AbstractThis paper presents the SINOD database, which is the first Slovenian non-native speech database. It will be used to improve the performance of large vocabulary continuous speech recogniser for non-native speakers. The main quality impact is expected for acoustic models and recogniser’s vocabulary. The SINOD database is designed as supplement …...

AbstractTo meet a variety of needs in information modeling, software development and integration as well as knowledge management and reuse, various groups within industry, academia, and government have been developing and deploying sharable and reusable models known as ontologies. Ontologies play an important role in knowledge representation. In this paper, …...

AbstractA WordNet is a lexical database in which nouns, verbs, adjectives and adverbs are organized in a conceptual hierarchy, linking semantically and lexically related concepts. Such semantic lexicons have become oneof the most valuable resources for a wide range of NLP research and applications, such as semantic tagging, automatic word-sense …...

AbstractMetadata descriptions of language resources become an increasing necessity since the shear amount of language resources is increasing rapidly and especially since we are now creating infrastuctures to access these resources via the web through integrated domains of language resource archives. Yet, the metadata frameworks offered for the domain of …...

AbstractLEXUS provides a flexible framework for the maintaining lexical structure and content. It is the first implementation of the Lexical Markup Framework model currently being developed at ISO TC37/SC4. Amongst its capabilities are the possibility to create lexicon structures, manipulate content and use of typed relations. Integration of well established …...

AbstractA number of serious reasons will convince an increasing amount of researchers to store their relevant material in centers which we will call "language resource archives". They combine the duty of taking care of long-term preservation as well as the task to give access to their material to different user …...
