Semantic Coordination for Document Retrieval

We present CtxMatch, an algorithm that finds mappings between two heterogeneous partially overlapping Classification Hierarchies (e.g. taxonomic structures used to organize documents). CtxMatch relies on the semantic interpretation of both the labels provides in the CHs and the hierarchical structures of the Chs; it does not consider the content of classified documents, thus allowing the retrieval of any kind of documents (e.g. text files, images, applications, videos, etc.). The Web Directories of Google and Yahoo! have been chosen as an evaluation set for discussing the performance of CtxMatch
