Abstract.
This paper describes GoNTogle, a framework for document annotation
and retrieval, built on top of Semantic Web and IR technologies. GoNTogle
supports ontology-based annotation for documents of several formats, in a fully
collaborative environment. It provides both manual and automatic annotation
mechanisms. Automatic annotation is based on a learning method that exploits user
annotation history and textual information to automatically suggest annotations for
new documents. GoNTogle also provides search facilities beyond the traditional
keyword-based search. A flexible combination of keyword-based and semantic-
based search over documents is proposed in conjunction with advanced ontology-
based search operations. The proposed methods are implemented in a fully
functional tool and their effectiveness is experimentally validated.
