OntoLog

Ontology-Based Annotation of Video and Audio

Introduction

Looks *really* good – Danny Ayers

OntoLog is a tool for annotating (describing and indexing) video and audio using ontologies – structured sets of terms or concepts. It is designed to be flexible and adaptable; you can to a large degree decide yourself how you want to describe your data – what properties to use, what level of detail and completeness to use, and how to organise and describe your ontologies. It is also designed to be usable right off the bat with little setup. It contains default description schemes that are usable for most purposes (and that are widely used Internet standards as well), and creating a simple ontology (or importing an existing one) is fast and straightforward.

OntoLog was developed as part of my doctoral studies at IDI, NTNU. My objectives with this work were primarily

to explore the issues of enabling flexible, user-defined description schemes and application profiles,
to simplify production of semantic, temporal annotations by using user-defined ontologies or vocabularies, and
to experiment with a novel visualisation of temporal annotations.
