In order to do such an analysis, a method of computer intensive hypothesis testing was developed by SAIC for the MUC-3 results and has been used for distinguishing MUC scores since that time. The implementation of this method for the MUC evaluations was first described in [1] and later the concepts behind the statistical model were explained in a more understandable manner in [2]. This paper gives the results of the statistical testing for the three MUC-6 tasks where a single metric could be associated with a system's performance.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128748706","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}

It improves on the original approach by: (1) grounding the scoring scheme in terms of a model; (2) producing more intuitive recall and precision scores; and (3) not requiring explicit computation of the transitive closure of coreference. The principal conceptual difference is that we have moved from a syntactic scoring model based on following coreference links to an approach defined by the model theory of those links.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128200262","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}

For the Named Entity task, SRA adapted a subset of NameTag's capabilities to the MUC-6 specification. For the Template Element task, SRA fed the full results of NameTag into HASTEN, which performed additional processing to extract and generate the organization and person templates. For the Scenario Template task, SRA fed NameTag's results into HASTEN, which used its full extraction capabilities to extract and generate the management succession templates. Figure 1 illustrates the contribution of each system to the MUC-6 tasks. Due to the relative complexity of the scenario template task, this paper will focus on HASTEN and the experimental results for scenario extraction, and will provide brief descriptions of NameTag and the other tasks.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"940 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116429692","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}

The FASTUS system was originally developed for participation in the MUC-4 evaluation [3] in 1992, and the performance of FASTUS in MUC-4 helped demonstrate the viability of finite state technologies in constrained natural-language understanding tasks. The system has undergone significant revision since MUC-4, and it is safe to say that the current system does not share a single line of code with the original. The fundamental ideas behind FASTUS, however, are retained in the current system: an architecture consisting of cascaded finite state transducers, each providing an additional level of analysis of the input, together with merging of the final results.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134002032","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}

The PIE system, on the other hand, relies heavily on a principle-based broad-coverage parser, called PRINCIPAR [2, 6, 8], that we have developed over the past three years. Most of the information extracted are directly \"read-off\" the parser outputs by a subtree pattern-matcher, bypassing the usual step of constructing semantic representations.","PeriodicalId":424990,"journal":{"name":"Message Understanding Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114434067","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}

We knew we would need an alternative to traditional linguistic grammars, even to the somewhat non-traditional categorial pseudo-parser we had in place at the time.
