Welcome to Konstantinos' OLD personal (semantic) Web document. This document (written in XHTML) is based on early efforts to provide both human and machine readable portions of a specific content (RDF-in-HTML). From this URL he also provides machine process-able content of this document (as an example case), in form of OWL annotations (from SWRC ontology) and additional metadata such as VCard, Dublin Core and FOAF (click the icons below).

Research Topics
Ontology Engineering (read his work on HCONE and SharedHCONE ontology engineering environment and HCOME methodology)
Ontology alignment (read his work on HCONE-merge and AUTOMS methods/tools towards automatic alignment of ontologies)
Semantic Web technologies (Grid ontologies/services matchmaking (SIS), Search engines, Wiki4OE, ...)
Semantic Web applications (in e-learning, environmental engineering) focusing on semantic interoperability
Semantic Web Services
Short Description of Ph.D research
The aim of his thesis was the design and implementation of multilingual
collaborative ontological environments for the management of
knowledge from non-expert users. The main objective was to
identify the human factors and needs during the use of such
environment in order to finally shift from a machine-centered
ontology management to human-centered one. The ultimate goal was to
build new generation environments where the distributed around
the world Knowledge Workers (domain experts) will be the
in-collaboration end-users without needing any support by the
Knowledge Engineers.
His research towards ontology management tools and
methods has accentuated the role of human-centered computing
within the loop of knowledge (ontology + information)
construction and consumption, and at the same time has presented
the principles, framework, and key issues of the design and
development of HCONE (Human-centered Collaborative Ontological
Engineering Environment). His major intention was to motivate
future knowledge and ontology management tools’ designers to
strongly consider human factors and a collaborative ontology engineering
methodology called HCOME (Human Centered Ontology Engineering Methodology).
One of the most important research he has carried out concerned on automating ontology
mapping process using the intended interpretations of terms for mapping concepts.
To accomplish an effective (minimum user involvement) mapping between the
intended interpretations and the concepts of ontologies, WordNet and
Latent
Semantic Indexing (LSI) were utilized.
