基于Ontology的Web文本分类法

传统方法处理文本分类时都需要进行文本训练,并且在文本表示时需要抽取特征项。搜集训练文本的过程需要费时费力的人工参与,而且中文信息的特征项抽取工作难度较大。为了解决这些问题,本文探讨了一种新的文本分类法———基于Ontology的Web文本分类法。该方法首先通过“知网”建立一个Ontology,然后根据分类体系建立每个类的Ontology,最后根据每个类的Ontology对文本进行分类。试验表明这种分类法与KNN分类法在准确率上相当,但比KNN方法稳定,在召回率上优于KNN方法。

Humanities E-Books: An Affective Faculty Survey

Subject specialists seek to understand humanists' perceptions of e-books. The investigator conducted an online survey of humanities faculty at The College of New Jersey (TCNJ) to find out. The survey uncovered information about the e-book collections humanist scholars benefit from most. Respondents used and valued e-books but felt printed books were more important in their disciplines. The major disadvantages of e-books outnumbered the major advantages in scholars' estimation, but the desire for ready access to book content largely eclipsed their affinity for print and any perceived disadvantages of the e-book format. The investigator considers implications for local humanities collection development.

The American Community Survey: An introduction to the basics

The Bureau of the Census initiated the American Community Survey (ACS) in 2005. It will revolutionize the use of census data by providing annual updates to statistics that in the past were collected only every 10 years. Statistics will be published for areas of 65,000 people or more every year. The Bureau of the Census will distribute data for areas of between 20,000 and 64,999 in "3-year period averages." The first 3 year average will appear in 2008 covering 2005–2007. Subsequent data will be issued annually for the following three year periods. (e.g., 2006–2008, 2007–2009) Statistics for areas smaller than 19,999 will be published in 5-year period averages, the first to be published in 2010 covering 2005–2009. Subsequent data to be issued annually will cover 2006–2010, 2007–20011, … This paper provides background information about ACS, similarities and differences between it and the decennial census, the interpretation of statistics based upon period averages, relationships among ACS and other Bureau of the Census Surveys, and the expected future of the survey.     

Public Service Broadcasting in Four Countries: Overview

The structure, funding, and audience size of public service broadcasting (PSB) revealed in the four countries examined in the articles in this issue of The Journal of Media Economics differ markedly from one another but exhibit few surprises. PSB in the United Kingdom, Australia, and Canada is highly centralized, but relatively decentralized in the United States. The United Kingdom devotes the largest proportion of its gross national product to PSB, and the United States devotes the smallest. Similarly, PSB in the United Kingdom attracts the largest share of the television audience among the four countries, and U.S. public television attracts the smallest. Although the future relevance of PSB in Canada may be at risk, the provision of PSB in the United Kingdom, Australia, and the United States seems likely to continue in its present form for the foreseeable future.
