中文简介:
在线知识的可用性的提高导致了一些算法的设计,这些算法通过收集语义网络来解决各种任务,即通过动态选择和探索大量在线本体。我们的假设是,这种新算法的性能隐式地提供了对所用本体质量的洞察,从而为基于任务的语义Web评估开辟了道路。我们通过研究在线本体在解决本体匹配、民俗学丰富和词义消歧三个任务中所学到的经验来研究这一假设。我们的分析得出了一系列关于语义网现状的结论,突出了在线语义信息的一些优缺点,并补充了其他语义网景观分析的结果。
课程简介: The increased availability of online knowledge has led to the design of several algorithms that solve a variety of tasks by harvesting the Semantic Web, i.e., by dynamically selecting and exploring a multitude of online ontologies. Our hypothesis is that the performance of such novel algorithms implicitly provides an insight into the quality of the used ontologies and thus opens the way to a task-based evaluation of the Semantic Web. We have investigated this hypothesis by studying the lessons learnt about online ontologies when used to solve three tasks: ontology matching, folksonomy enrichment, and word sense disambiguation. Our analysis leads to a suit of conclusions about the status of the Semantic Web, which highlight a number of strengths and weaknesses of the semantic information available online and complement the findings of other analysis of the Semantic Web landscape.
