Abstract

One of the main features of classic libraries is metadata, which also is the key aspect of the Semantic Web. Librarians in the process of resources annotation use different kinds of Knowledge Organization Systems; KOS range from controlled vocabularies to classifications and categories (e.g., taxonomies) and to relationship lists (e.g., thesauri). The diversity of controlled vocabularies, used by various libraries and organizations, became a bottleneck for efficient information exchange between different entities. Even though a simple one-to-one mapping could be established, based on the similarities between names of concepts, we cannot derive information about the hierarchy between concepts from two different KOS. One of the solutions to this problem is to create an algorithm based on data delivered by large community of users using many classification schemata at once. The rationale behind it is that similar resources can be described by equivalent concepts taken from different taxonomies. The more annotations are collected, the more precise the result of this crosswalk will be.
