摘要

There are two types of keywords used as metadata: controlled terms and free terms. Free terms have the advantagenthat metadata creators can freely select keywords, but there also exists a disadvantage that the information retrievalnrecall ratio might be reduced. The recall ratio can be improved by using controlled terms. But creating and maintainingncontrolled vocabularies has an enormous cost. In addition, many existing controlled vocabularies are published innformats less suitable for programming. We introduce a JavaScript library called “covo.js” that enables us to make usenof controlled vocabularies as metadata for the organization of web pages.
