Automatic evaluation of search ontologies in the entertainment domain using text classification Academic Article uri icon

abstract

  • Information Retrieval (IR) research has recently started addressing the information need of exploratory search. where the searcher may be unfamiliar with the domain or not have decided what is the goal of his query. A popular tool to support exploratory search is the use of faceted search. The implementation of faceted search requires that documents be annotated by metadata in the form of attributes and hierarchical categories. In many applications, the metadata is maintained manually, in the form of a search ontology. Recent work has also investigated methods to automatically acquire such metadata from sample documents [1, 2]. In this work, we propose a new method to automatically evaluate the quality of such a search ontology. Our method relies on mapping ontology instances to textual documents. On the basis of this mapping, we evaluate the adequacy of ontology …
