Intelligent Systems Laboratory - ISL


Intelligent Systems Laboratory was established in 2000. This laboratory primarily supports research on various aspects of intelligent systems, including semantic-web systems, multimedia databases, knowledge engineering, knowledge-based systems, automated reasoning, natural language processing, text mining, web service composition, artificial life, intelligent collaborative systems for technology-enhanced learning, neural networks, genetic algorithms, and robotics. The research groups currently work on various projects about semantic web technologies and ontology-based question answering systems.

Current Projects


Today's information and communication systems hold a huge amount of multimedia data. In addition to professionally produced multimedia content, user generated volume of multimedia content has been increasing dramatically with the advent of widely available sources such as mobile phones, digital cameras and recorders. The aim of this project is to develop architectures and technologies for intelligent ways of storing, searching, retrieving, managing, and consuming this enormous amount of data.

Metadata is necessary to understand and reason the multimedia content. This project will fully utilize widely accepted standards for describing multimedia data semantically. Existing multimedia data without sufficient metadata needs technologies like image processing, text mining and information extraction for generating semantic information.

Personalisation plays a key role in this project. The system will learn user profiles and continuously update them by considering usage histories. It can then find new multimedia content from TV broadcasts or Internet in accordance with the user profiles.


The main activities of the system involve the use of pedagogical approaches and the exploitation of interactivity and context-awareness. The interactivity will be provided by ontology-based question answering systems integrated into technology-enhanced learning systems. This way, users will be able to ask questions to the system in natural language and get appropriate answers from the system. Moreover, the system will be able to learn users' behaviour and configure itself accordingly. This framework provides faster and more effective ways of knowledge acquisition, and also increases user competences, and skills.

This framework also aims to develop standards for machine understandable content representation and for easy integration of question answering systems into technology-enhanced learning. The content generation phase has to be done by using special tools that help users create content in the norms of the standards.
