!Ontosum
''Ontology Management and Use to Support Summarization''

Ontologies constitute  the infrastructure of such systems in the Semantic Web and for this reason there are numerous endeavours towards the growth of relative  technologies funded by the IST programme of the European Union. The  research community today, not only conceives the role of ontologies  as the basic technology in the effective management of knowledge, but  also as a technology that contributes in the transformation of WWW in  the Semantic Web. The problems however that are related with the creation  of suitable ontologies, with their coordination (when more than one  ontologies exist on the same thematic region), as well as with their  effective maintenance, impede the spread of the Semantic Web and the  applications that it supports. The success of the Semantic Web and its  relevant technologies depend heavily on the fast and low cost growth,  co-ordination and development of multiple ontologies, as well as from  their effective exploitation of its various applications. Up  to today, these activities require high cost and a lot of time, in order  to be materialised by experts in the various thematic regions. The great importance of ontologies, requires the growth of new  techniques in the scientific region of ontology engineering, as well  as the innovative exploitation of ontologies from various brilliant  applications.

The project aims at the growth of new methods and techniques for:
# Learning of new ontologies from existing data bases (Ontology Learning from Databases)
# The coordination of existing ontologies (Ontology Coordination) on the same thematic region, with accent in their correspondence (mapping) and in their fusion (merging)
# The production of summaries with the use of ontologies (Ontology-based Summarization)

!CASAM
''Computer Aided Semantic Annotation of Multimedia''

CASAM introduces the concept of computer-aided semantic annotation to accelerate the adoption of semiautomatic multimedia annotation in the industry. The project is unique in that it facilitates the synergy of human and machine intelligence to significantly speed up the task of human-produced semantic annotation of multimedia content.

The proposed approach is motivated by the limitations of current efforts to fully automate multimedia content annotation, i.e. the immature machine-only annotation and the cost-prohibitive manual annotation.

The balance of the human and machine effort will depend on the context and complexity of the multimedia document. Therefore, it is particularly important that this balance is not predetermined and fixed, but rather adaptive to the situation. Hence, the novelty of CASAM lies in the difficult task of online aggregating human and machine knowledge with the ultimate target of minimizing human involvement in the annotation procedure.

!synC3
''Synergetic Content Creation & Communication''

The goal of SYNC3 is to create a framework for structuring, rendering more accessible and enabling collaborative creation of the extensive user-provided content that is located in personal blogs and refers to running news issues. The main obstacle for blogosphere content exploitation has been the difficulty to structure the disparate and vast information found in blog posts. On the other hand, news articles have a multitude of favourable characteristics that make their analysis easier. The pioneering concept of SYNC3 is that while the underlying semantics of news events is not studied, the news event is the most appropriate thematology atom for the task of associating user commentaries on news articles. SYNC3 can also derive relations between news events and connect them with blog post excerpts, while through sentiment analysis of these excerpts can derive user opinions that are associated to news events. The final product which combines news events and their relations and users and their opinions is the SYNC3 graph of the commentaries of blog users on current news. The graph is presented to the user through an intuitive interface which also enables the user to re-use the now structured content attached to the graph and create content collaboratively.
