Established in 1994, SZTAKI DSD (Department of Distributed Systems) played a pioneering role in the introduction and application of the Internet and WWW technologies in Hungary. Since the mid-90s DSD has specialized in the research and development of artificial intelligence, internet science, digital library and archiving systems, distributed knowledge management, distributed computer systems, applications and middleware including World Wide Web-based software systems, web, semantic web, groupware applications and services, CSCW, digital art projects and mobile computing.

In the picture below DSD scientific areas are introduced which, based on web, cloud and several other technologies, and enforced by the three DSD-specific pillars, support our present work related to artificial intelligence and internet science.

DSD gives priority to the planning and development of distributed network infrastructures that support the research and development of AI (artificial intelligence), and to the research and development regarding the special services of data management tasks in these infrastructures.

Infrastructural approach enables DSD to directly apply its know-how created in the areas of data management, graph-based knowledge management and semantic web, and to integrate it into a unified research and development supporting system. 

DSD develops specialized artificial intelligence solutions and applications for data filtering and data cleansing particularly related to research data handling.

Facing today’s challenges regarding the load and diversity of information and digital content, DSD is actively involved in the research and development (methods, technologies, applications) of digital library and archiving systems, repositories, metadata registers, semantic data management and data storage services (nowadays, most significantly for artificial intelligence) which aim at ensuring usability, accessibility, scalability and long-term preservation.

Current activities of DSD involve, with the help of virtualization methodology and middleware software, and using cloud or cloud related network services (cloud, fog, edge, P2P computing), the development of knowledge management systems, semantic web, linked data architectures, platforms, methods and tools that enable content awareness, personalization and dynamic service- and datafusion. 

DSD also initiates research to form the service system for the Internet of the Future. It has also conducted research and development in the architectural, functional and user interface aspects of groupware including calendar/agenda applications, group based project management systems, workflow systems, meeting support systems, discussion forums, decision support and voting systems.

Our mission

Our main task is to find solutions to problems where such unique and special IT knowledge is needed where only few try. We take the challenge to enter research and development projects, where interdisciplinarity inside and out of informatics is inevitable, and where our colleagues can show their wide range of expertise, interests and experience.  

Great emphasis is put on reliability: DSD would rather not undertake a task if we are not absolutely certain that a solution of outstanding quality is delivered on time. However, high quality solutions are not presented only on commission or due to project obligations. During „in-between-projects” time several, for the Hungarian society, important and useful activities have taken place – not as if our projects have been fruitless. As a result, among others, the most popular Hungarian on-line dictionary service SZTAKI Szótár was created in 1994, serving 40,000 users every day.

DSD develops complex systems, let them be either abstract (theoretical fundamental research) or operating and complicated software systems along the paradigm of post-academic scientific research and knowledge creation. When developing systems, we mainly use JAVA, Javascript, PHP, SQL, SPARQL, JSON, but we may also turn to other technologies. Rarely we use PERL, but deny it afterwards.
