This Computing Research Infrastructure planning grant addresses two challenges for automatic systems performing deep semantic processing: identifying the context-appropriate sense of polysemous words and interpreting the meanings and interrelations of verbs and nouns in event-denoting phrases. Preliminary steps are taken for aligning and linking four existing widely used lexical resources (WordNet, FrameNet, PropBank and VerbNet) with different but complementary contents and coverage. Methods for completing current cross-resource links and full transitive closure are explored and tested. The resulting infrastructure (LexLink) is designed to make the resources fully interoperable, capitalizing on their particular strengths with respect to word sense disambiguation and Semantic Role labeling.Four activities are carried out in the context of planning LexLink. First, a workshop is held where key representatives of the Natural Language Processing and computational semantics communities articulate needs and requirements for the planned resource and offer advice on algorithms, annotation techniques and evaluation. Second, a subsection of cross-resource links for word senses and Semantic Role labels (Agent, Instrument, etc.) resulting from the automatic transitive closure is evaluated, yielding estimates for the error rate and leading to fine-tuning of algorithms. Third, current best performing mapping algorithms for word senses and Semantic Role labels are evaluated against a human-annotated Gold Standard. Fourth, new Gold Standard data are created for additional training and testing and to refine existing algorithms. As a whole, the work provides a solid foundation for a resource with significant beneficial impact on a range of natural language applications, including machine translation, text summarization and sentiment analysis affecting areas such as health care, marketing, and education.

这项计算研究基础设施规划拨款解决了自动系统执行深度语义处理的两个挑战：识别多义词的上下文相关意义，以及解释事件表示短语中动词和名词的含义和相互关系。初步的步骤，调整和连接四个现有的广泛使用的词汇资源（WordNet，FrameNet，PropBank和VerbNet）不同，但互补的内容和覆盖面。探索和测试完成当前跨资源链接和完全传递闭包的方法。由此产生的基础设施（LexLink）的目的是使资源完全互操作，利用其特定的优势，在词义消歧和语义角色labeling.Four活动的规划LexLink的背景下进行。首先，举办一个研讨会，自然语言处理和计算语义社区的主要代表阐明计划资源的需求和要求，并提供算法，注释技术和评估方面的建议。第二，一个子部分的跨资源链接的词义和语义角色标签（代理，仪器等）。从自动传递闭包产生的结果进行评估，产生错误率的估计，并导致算法的微调。第三，目前表现最好的映射算法的词义和语义角色标签进行评估，对人类注释的黄金标准。第四，创建新的黄金标准数据用于额外的训练和测试，并改进现有算法。总的来说，这项工作为资源提供了坚实的基础，对一系列自然语言应用产生了重大的有益影响，包括机器翻译，文本摘要和情感分析，影响了医疗保健，营销和教育等领域。
