EIA-0205448Joshi, AravindUniversity of PennsylvaniaITR: Mining the Bibliome -- Information Extraction from the BiomedicalLiterature The major goal is the development of qualitatively better methods for automatically extracting information from the biomedical literature, relying on recent research in high-accuracy parsing and shallow semantic analysis. The special focus will be on information relevant to drug development, in collaboration with researchers in the Knowledge Integration and DiscoverySystems group at GlaxoSmithKline. This project will also address several database research problems, including methods for modeling complex, incomplete and changing information using semistructured data, and also ways to connect the text analysis process to an information integration environment that can deal with the wide variety of extant bioinformatic data models, formats, languages and interfaces.The engine of recent progress in language processing research has been linguistic data: text corpora, treebanks, lexicons, test corpora for information retrieval and information extraction, and so on. Much of this data has been created by Penn researchers and published by Penn's Linguistic Data Consortium. Hence, one of our major goals is to develop and publish new linguistic resources in three categories: a large corpus of biomedical text annotated with syntactic structures `Treebank' and shallow semantic structures (proposition bank or `Propbank'; several large sets of biomedical abstracts and full-text articles annotated with entities and relations of interest to drug developers, such as enzyme inhibition by various compounds or genotype/phenotype connections `Factbanks'; and broad-coverage lexicons and tools for the analysis of biomedical texts.

EIA-0205448Joshi，Aravind 宾夕法尼亚大学ITR：挖掘文献库——从生物医学文献中提取信息主要目标是依靠高精度解析和浅层语义分析的最新研究，开发质量更好的方法，从生物医学文献中自动提取信息。将与葛兰素史克知识整合和发现系统小组的研究人员合作，特别关注与药物开发相关的信息。 该项目还将解决几个数据库研究问题，包括使用半结构化数据对复杂、不完整和变化的信息进行建模的方法，以及将文本分析过程连接到可以处理各种现有生物信息数据模型的信息集成环境的方法、格式、语言和界面。语言处理研究最新进展的引擎是语言数据：文本语料库、树库、词典、用于信息检索和信息提取的测试语料库等等。其中大部分数据是由宾夕法尼亚大学研究人员创建的，并由宾夕法尼亚大学语言数据联盟发布。 因此，我们的主要目标之一是开发和出版三类新的语言资源：用句法结构“树库”和浅层语义结构（命题库或“Propbank”）注释的大型生物医学文本语料库；几套大型生物医学摘要以及注释有药物开发商感兴趣的实体和关系的全文文章，例如各种化合物或基因型/表型连接的酶抑制“事实库”以及广泛覆盖的词典和工具；生物医学文本的分析。
