Controlled and uncontrolled indexing terminology and metadata may be converted from one to another. Decision criteria are developed that can be used to determine which terms should be assigned when converting vocabularies. Methods are developed for computing the parameters of these systems, as well as means for estimating the parameters when given limited information. These conversion technique...

Managing change in controlled medical vocabularies is labor intensive and costly, but change is inevitable if vocabularies are to be kept up to date. The changes that are appropriate for a controlled medical vocabulary depend on the data stored for that vocabulary, and those data in turn depend on the needs of users. The set of change operations is the change model; the data stored about concep...

This chapter presents an analytical study about methodology and methods to build ontologies and controlled vocabularies, compiled by the analysis of a literature about methodologies for building ontologies and controlled vocabularies and the international standards for software engineering. Through theoretical and empirical research it was possible to build a comparative overview which can help...

The Simple Knowledge Organization System (SKOS) is a standard model for controlled vocabularies on the Web. However, SKOS vocabularies often differ in terms of quality, which reduces their applicability across system boundaries. Here we investigate how we can support taxonomists in improving SKOS vocabularies by pointing out quality issues that go beyond the integrity constraints defined in the...

As language data and associated technologies proliferate and as the language resources community rapidly expands, it has become difficult to locate and reuse existing resources. Are there any lexical resources for such-and-such a language? What tool can work with transcripts in this particular format? What is a good format to use for linguistic data of this type? Questions like these dominate m...

This paper presents an architecture to place index references from control vocabularies into XML documents. This provides three advantages currently not present in XML: the ability to simplify the writing of complex document type definitions that refer to control vocabularies, the ability to write XML documents with better indexing, and better retrieval of XML documents.
