It includes a core English lexicon and grammar, a concept network, processes for applying these to lexical, syntactic, semantic, and discourse analysis, and tools that support the adaptation of the generic core to new domains, primarily by acquiring sublanguage and domain-specific lexicon and conceptual topic patterns of interest. The lexical, syntactic, and semantic analysis components were completed before MUC-4 and required little adaptation. The discourse analysis component is new and was completed in the course of applying the system to MUC-4, although it is generic. The overall system is described in [1]. The present description concentrates on discourse analysis.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130432662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to being a domain-independent NLP system, starting in the fall of 1990, SOLOMON has been extended as part of the MURASAKI project to become a multi-lingual text understanding system. It currently understands Spanish and Japanese as well as English texts. In order to achieve domain- and language-independence, SOLOMON separates data from processing modules. The processing modules do not assume any domain- or language-dependent facts; rather they are designed so that they work off separate data, i.e. lexicons, grammars, patterns, and knowledge bases, which vary according to the domain or language. To facilitate data acquisition, SRA has developed 2 tools: LEXTool for the development of lexicons and KBTool for the development of knowledge bases.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124014916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study showed a degradation in correctness of message processing as the information distribution in the message became more complex, that is, as slot fills were drawn from larger portions of the message and required more discourse processing to extract the information and reassemble it correctly in the required template(s). The study also suggested that systems did worse on messages requiring multiple templates than on single-template messages. These observations led us define the MUC-4 adjunct test to examine two hypotheses related to discourse complexity and expected system performance:• The Source Complexity HypothesisThe more complex the distribution of the source information for filling a given slot or template (the more sentences, and the more widely separated the sentences), the more difficult it will be to process the message correctly.•The Output Complexity HypothesisThe more complex the output (in terms of number of templates), the harder it will be to process the message correctly.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131982333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
