Building an ontology based on hub words for information retrieval
Sang Ok Koo, Soo Yeon Lim, Sang Jo Lee · 2004
We suggest a semiautomatic ontology construction method based on hub words. To do this, we define the words that are related to many other words as hub words. We determine the hub words by the statistical analysis of documents. Additionally, we discuss the base ontology construction process based on hub words and automatic ontology extension method. The proposed ontology can be used like an index file for traditional document retrieval and can offer more semantic information than simple index files.
