Finding the right term: Retrieving and exploring semantic concepts in astronomical vocabularies

Astronomy, like many domains, already has several sets of terminology in general use, referred to as controlled vocabularies. For example, the keywords for tagging journal articles, or the taxonomy of terms used to label image files. These existing vocabularies can be encoded into skos, a W3C proposed recommendation for representing vocabularies on the Semantic Web, so that computer systems can help users to search for and discover resources tagged with vocabulary concepts. However, this requires a search mechanism to go from a user-supplied string to a vocabulary concept.     

The StartwithXML Project: Understand the Point and Path to a Digital Workflow

To pursue emerging revenue opportunities in the most cost-efficient way (or sometimes to be able to pursue them at all), book publishers are going to have to adopt a StartwithXML workflow. That means their content needs to live in an XML-structured document from the earliest possible moment, which could be “inception”, and carry within it metadata about the document structure, the content itself, and the rights to all components. The tools exist to do this, but the organizational challenges of changing workflows and inventing new procedures are daunting. This project explores the business case and the implementation challenges, including case studies of companies who have already begun to work this way.     

XML: Why Bother?

An XML-first workflow provides a framework that will empower publishers to move from a print-centric to a content-centric creation process, freeing them to find new and creative ways to present content to the world, to connect with readers in new ways. XML is far more than a production workflow—it is the medium that will allow publishers to deliver their message most effectively, and will enable a rapid and necessary evolution in the way publishers manage and disseminate an author’s content.     

基于协同标注的B2C电子商务个性化推荐系统研究

针对B2C电子商务系统中“信息过载”与“信息缺失”共存的问题,在综合分析电子商务个性化推荐技术和协同标注基础上,提出采用协同标注方法构建推荐系统为顾客提供个性化的商品信息,描述了该系统的总体结构,并对系统中的概念生成器、查询分析器、商品标签地图等功能模块进行详细论述。     

汉语人名标注及其方法

论述了汉语中词、短语和短语词的概念，在此基础上讨论了中信息处理中的汉语人名的标注问题以及相关的“专名 通名”式短语词的标注问题，提出了汉语人名的标注方法。这一问题的研究，对于汉语自动切词研究具有重要作用。     

最新标签本体：标签和民俗分类法语义模型

当前,人们越来越关注协作化标签系统中标签数据的表示和共享。传统的标签（指随意标注的、没有与结构化本体相关联的标签）由于语言和语法的差异以及录入错误等,不适于做协作化处理。而且标签反映的是用户个人的观点,也不对同义词、词形变化或者其他对照映射关系做规范处理。因此笔者认为,标签的常规处理方法对语义协作的贡献非常有限,即便是有,要让计算机实现自动共享也是极其困难的。在语义层面上讨论数种协作标签标注的方法,提出一个标签协作标注和设计民俗分类法的概念模型,同时比较已有的标签本体,提出一个评价标准,并参照该标准讨论这些标签本体的优缺点。
