Ambiguity is a central problem for operators working in dynamic, high‐risk environments. Operators must decide on a course of action before knowing with certainty how the system will respond. Though ambiguity is expected, how it presents is unexpected. We reduce ambiguity when we can give meaning to information and events through use of context, responsiveness of the system, and when we can view events from a higher level. Preparation and training for routine operations helps identify potential ambiguities before events begin. The experienced operator engages the situation relying on real‐time experience to learn what works through action, thus further reducing ambiguity. 相似文献

We describe a memory-based classification architecture for word sense disambiguation and its application to the SENSEVAL evaluationtask. For each ambiguous word, a semantic word expert isautomatically trained using a memory-based approach. In each expert,selecting the correct sense of a word in a new context is achieved byfinding the closest match to stored examples of this task. Advantagesof the approach include (i) fast development time for word experts,(ii) easy and elegant automatic integration of information sources,(iii) use of all available data for training the experts, and (iv)relatively high accuracy with minimal linguistic engineering. 相似文献

Folksonomies, often known as tagging systems, such as the ones used on the popular Delicious or Flickr websites, use a very simple Knowledge Organisation System. Users have thus been quick to adopt this system and create extensive annotations on the Web. However, because of the simplicity of the folksonomy model, the semantics of the tags used is not explicit and can only be inferred from their context of use. This is a barrier for the automatic use of such Knowledge Organisation Systems by computers and new techniques have been developed to extract the semantic of the tags. In this article we discuss the drawbacks of some of these approaches and propose a generalization of the different approaches to detect new senses of terms in a folksonomy. Another weak point of the current state of the art in the field is the lack of formal evaluation methodology; we thus propose a novel evaluation framework. We introduce a dataset and evaluation methodology that enable the comparison of results between different approaches to sense induction in folksonomies. Finally we discuss the performances of different approaches to the task of homonymous/polysemous tag detection and synonymous identification. 相似文献

在漫长进化过程中人类逐渐发现:仅靠自身的五个感觉器官接收外界信息已不能满足制造较为复杂的劳动工具以及探寻自然界奥秘的需要,为谋求生存和发展,必须制作能够替代和扩展五官功能的工具。因此自从古埃及人发明了天平,传感器便与人类结下了不解之缘。如今历史车轮已碾进二十一世纪,人类的部分劳动也已交由机器人完成。在众多机器人中智能机器人的工作过程完全模仿了人体的活动机理:感觉传感器将外界信息传送给相当于人脑的计算机处理,相当于人体四肢的执行机构则按计算机指令操作。下面我们就将人体五官与感觉传感器作一个对比介绍… 相似文献

This paper specifically addresses the question of polysemy with respect toverbs, and whether or not the sense distinctions that are made in on-linelexical resources such as WordNet are appropriate for computational lexicons.The use of sets of related syntactic frames and verb classes are examined as ameans of simplifying the task of defining different senses, and the importanceof concrete criteria such as different predicate argument structures, semanticclass constraints and lexical co-occurrences is emphasized. 相似文献
