The Active Knowledge Engineering Laboratory activities are focused on research and development of new approaches on knowledge representation as well as involving them into different application areas. The current research topics are the following:
1. Filmfications of Methods and Data
Existing systems of symbols and notations are usually very abstract and there is a great gap between the form and meaning of data/knowledge. Our long-term education, in an essential part, is reduced to training our brain for being 'encoding-decoding' machine bridging this gap. The abstractness mentioned and bridging operations are sources of serious mental and physical problems for a great variety of people and, especially for disabled and elderly. Our aging society is also becoming information society. So, the above-mentioned aspect of our environment is becoming crucial. That is why, our research is to develop a new environment with lesser level of abstraction and with the better quality of people life. Our general program is cyber-infrastructure including high-performance computing. We are also thinking about active knowledge being developed by humanity and undertaking research efforts in visual (multimedia) languages and tools, parallel and distributed systems. In a great part, our research and development are based on an idea of self-explanatory components in a cyberFilm format. A cyberFilm is a set of color stills supported, if necessary, by text, voice/sound and special links. Each still is to represent a view (some features) of objects or processes. Each cyberFilm is to represent a multiple view (an extended set of dynamic and/or static features) of objects or processes. The more accurate and relevant views are used, the greater adequacy is reached. The idea of cyberFilms is used for the specification of information resources and programming operations with the resources, as well as for the representation of multimedia messages and implementation of human-computer interfaces. The idea of equal opportunities to all individuals in the use of information resources is used to create a right set of cyberFilms and methods of their adaptation. We lead four clusters of projects related to filmification of methods and data: 1) Active Knowledge Studio for teachers, students, and programmers, 2) Semantic Surfaces in Ambient Living Environments for elderly, 3) Virtual objects, haptic interface and 3D printers for rapid prototyping, and 4) WWW-based software for users involved in multimedia programming and distance learning.
2. Human-Computer Interaction and Natural Language Parsing
Experimenting with human behavior via human-computer interaction is challenging and interesting topic with many possible problems. Our research interests include: - Artificial intelligence systems for computer games; - Virtual experiments based on human-computer interaction; - Understanding and modeling human behavior. Natural language processing is a challenging branch of modern artificial intelligence. Its applications include text analysis, machine translation, computer-assisted language learning, grammar checking, and information retrieval. Our current research is mostly focused at parsing, i.e. at analysis of language sentences in order to discover dependencies between individual words.
3. WWW-based Ubiquitous Environment for e-Learning and High-Performance Computing
The main goal of the project is in research and development of the multi-purposed Distributed Heterogeneous Environment that can easily be adapted to the different application areas. The basic system architecture consists of the server and client parts. The server part will include developing a set of utilities allowing programming and adaptation to the user's profiles and concrete application area. It will also include a set of tools supporting visual programming and Internet computing. We are based on a concept of the Movie-Based Programming using a movie-like representation of algorithms and methods. This environment supports different types of the user's projects distinguished according to programming platforms and languages, type of a target machine, user's specialization, etc. The set of application-oriented clients can be realized as usual workstations increasing the total computational power of the system as well as end-user mobile ubiquitous devices created on the basis of embedded technologies. The e-Learning Task Management subsystem is focused on systems supporting management of exercises and tests requiring not only numerical answers but also mathematical expressions or formulas. The originality of the proposed research is in developing the special visual tool to input and verify arithmetic/logical expressions, as well as special user-oriented interface using multimedia icons and high-level program keyboards. Accordingly, the client part as an ubiquitous multimedia calculator in order to support task solution process for problems from math, physics, chemistry, etc. Modern computational technologies are making possible to calculate rather well tsunami wave propagation over the deep ocean provided that initial displacement is known. The set of tsunami scenarios includes of many pre-calculated data of possible tsunami behaviors according the epicenter coordinates, coast shape, features of media, etc. A public server client/server architecture and infrastructure is developing developed including input/output parameters of numerical tasks for remote computational facilities as well as structure of tsunami data to be stored and assembled.
