Markup of a Test Suite with SGML

Recently, there have been various attempts to set up a test suite covering the syntactic\udphenomena of a natural language (cp. [Flickinger et al. 1989], [Nerbonne et al. 1993]).\udThe latest effort is the TSNLP project (Test Suite for Natural Language Processing)\udwithin the Linguistic Research and Engineering (LRE) framework sponsored by the\udEuropean Union (cp. [Balkan et al. 1994]). These test suites are meant for the testing of\udNLP software regarding their coverage of syntactic phenomena. [Volk 1995] showed that\uda well-organised test suite can also be used to support incremental grammar development\udand grammar documentation. The key issues in the organisation of a test suite are the\udease of extensibility and interchangeability as well as the avoidance of redundancy. We\udhave implemented a test suite, which is optimized for the avoidance of redundancy and\udwe report on the trade-off for extensibility and interchangeability
