Ongoing Projects
Stratuslab – "Enhancing Grid Infrastructures with Virtualization and Cloud Technologies"
PRESEMT – "Pattern REcognition-based Statistically Enhanced MT "
The PRESEMT project is a European funded project that intends to provide a flexible and adaptable MT system based on a language-independent method. PRESEMT aims to address the issue of effectively managing multilingual content and proposes a language-intependent machine-learning-based methodology. The produced result by the translation procedure is adapted to the preferences of the user's and adapts to their requirements. Moreover, parallelization techniques are applied to boost up performance. (www.presemt.eu)
Stratuslab is a co-funded programme by the European Community's Seventh Framework Programme aiming at deploying distributed computing infrastructures with a purpose-built and open-source cloud distribution. The developed cloud distribution enables the efficient execution of scientific research using cloud computing power. Stratuslab follows the Infrastructure-as-a-Service (IaaS) cloud paradigm and it mainly focuses on the development of novel services for grid computing and other scientific applications in private clouds.The StratusLab distribution builds on-top of popular infrastructure virtualization solutions like KVM and OpenNebula and addresses cores aspects for the provisioning of computing resources related to computing power (life-cycle management of virtual machines), storage, networking, appliance management.

Past Projects
EGEE II & EGEE III – "Enabling Grids for E-sciencE"
GREDIA – "Grid Enabled Access to Rich Media Content"
GridNews – "A distributed Grid-enabled Platform for the Efficient Provisioning and Querying of Audiovisual Content"
The EGEE projects (www.eu-egee.org) aimed at building a large-scale distributed infrastructure of production level based on Grid technologies. This infrastructure is avaliable as a service to scientists independent of the geographic location, while the operation of the infrastructure was continuous offering seamless access to computational and data resources. A basic initiative of the project was the wide adoption of the infrastructure for the execution of applications from various scientific fields. In the context of this initiative, I participated as a lecturer in many seminars in greek universities and academic institutions (e.g. (http://indico.cern.ch/conferenceDisplay.py?confId=23475, http://indico.cern.ch/conferenceDisplay.py?confId=27626).
The design of a generic middleware for efficient search and retrieval of annotated content in a distributed Grid environment has been largely motivated by the requirements posed by the GREDIA research project, supported by the European Committee. GREDIA’s main objective is the development of a Grid application platform, providing high level support for the implementation of Grid business applications through a flexible graphical user interface. This generic platform facilitated the provision of business services, which mainly demand access and sharing of large quantities of distributed annotated numerical and multimedia content. Furthermore, the GREDIA platform exploited Grid technologies to enable access to the distributed content by mobile devices. A user may access the platform in order to upload content or perform searches. www.gredia.eu
The goal of this National funded project was the storage and processing of high fidelity audio-visual material from television signals for the efficient identification of segments containing specific keyword. It aimed to create an integrated information system based on Grid technologies, where users were able to identify and then reproduce audio-visual segments by keyword searches.
