Dear all
After a more inside exploration on the tools for image annotation, here are
some
basic characteristics that could be used for the categorization of the
tools.
1) Type of content: Jpeg Images,Video etc
2) Type of metadata: Descriptive, administrative, structural etc
3) Format of metadata: OWL, RDF
4) Annotation Level: Extraction of visual characteristics and association
with domain ontology concepts-operation using ontologies.
5) Operation mode: plug-in, stand-alone
6) Open source: YES, NO
Concerning the benchmarking, it could be based on the creation of some
examples
taken from the use cases which will be annotated with the aid of all the
tools. In my
opinion, it is better to avoid criticism on the tools. It is rather better
to provide the
users with the output of the tools and leave them to decide which is better
for their
application.
Best Regards,
Nikolaos Simou.
