Web Services and Processing Pipelines in HLT: Tool Evaluation, LR Production and Validation WORKSHOP PROGRAMME

At the end of 2009 the review of a number of available Web services implementing linguistic processing chains (CLARIN deliverable D5R-3a, 2009) was prepared as part of Common Language Resources and Technology Infrastructure (CLARIN) Working Group 5.6 (LRT integration) activities. Basing on the showcases contributed by WG members, the summary of features of both chained and individual Web Services was compiled, preparing the ground for comparisons between selected linguistic properties of registered frameworks. The article aims at presenting preliminary generalizations regarding functionalities, communication standards and representation of linguistic resources being adopted as web services, which were initially put forward in the CLARIN paper. The major features of the tools are summarized to provide starting point for discussion over interchange formats and tagsets, standards of encoding of linguistic resources and linguistic data categories. Apart from concentrating on representation of linguistic annotation, very preliminary conclusions concern technical, formal and semantic interoperability of language resources.
