Intelligent Interface for Knowledge Based System

2014

Every knowledge-based system has its own knowledge formalism depending on the problem that needs solving, goal to be achieved, and proposed solution. This means the knowledge contained in the system will differ from one system to another. This also means that this knowledge cannot be used by another system, which in turn means every system must start with a learning phase right at the beginning. One of the solutions to overcoming this problem is providing a unified model that can accept all types of knowledge, which guarantees automatic interaction between the knowledge-based systems. Interaction in this paper is defined as knowledge sharing, integration, and transfer from one system to another. This research provides a model and conducts a test on interaction capability. It will help to accelerate the establishment of a new knowledge-based system because it does not need knowledge initialization.

The process of generating user interfaces is complex and demands a great deal of effort from the specialist, because there are several possible combinations and uncertainties regarding any one option. We believe that the modeling of HCI concepts and of the knowledge of all parties involved is of great importance, as well as the reuse of this modeling to automate and optimize such process. Therefore, we are proposing a KBS (Knowledge-Based System) that represents the knowledge of the interface designers. This System possesses the feature of interactivity, so that the user can have an explanation of the results produced, thus improving the understanding and acceptance of the proposed interface. Furthermore, the system allows for its knowledge base to be modified. We applied the proposed method to generate an abstract user interface for a system of email control and for a system of simulation of criminal activity.

The process of group decision making requires a set of databases and knowledge bases with coordinated communication between them. A distributed knowledge-based system consists of several knowledge-based systems, and there is a possibility for their physical or logical separation. The article presents the conceptual model of a distributed knowledge-based system. The suggested architecture supports sharing and integration of knowledge and data in addition to allowing heterogeneous knowledge-based systems to communicate with each other. The article also outlines the implementation of interaction protocols comprising intelligent objects which cooperate with each other in order to find solutions to assigned tasks. Keywords – Decision support systems, Distributed knowledge-based system, Interaction protocols, Multi-agent systems.

Knowledge-Based Systems (KBS) are computer programs based on technologies established by Artificial Intelligence research, which express some characteristics of human knowledge and expertise to perform tasks normally done by human experts. Thus, a knowledge-based system has two distinguishing features: a knowledge base and an inference engine. The first part, the knowledge base, represents facts about the world. The second part, the inference engine, allows new knowledge to be inferred. Most commonly, it can take the form of IF-THEN rules coupled with forward or backward chaining approaches. The paper introduce the concept of knowledge based systems, Architecture of a Knowledge-Based System, Tools for Building KnowledgeBased System, and brief introduction to the most popular knowledge based systems found in the literatures.

ATLAS (EP 7280) is a collaborative research project to improve the competitiveness of European Large Scale Engineering companies within the world market. The project focuses on the development of software Architectures and Tools based on non proprietary information exchange standards such as STEP and EDIFACT to improve business integration and co-ordination. The understanding of software integration does not only cover classical engineering applications but also addresses knowledge based systems (i.e. rule based and case based) by means of STEP based AI environments including a LISP binding of the SDAI specification (STEP Part 22). The work undertaken during the course of the project opens the road to the future integration of KB systems within STEP architectures. ATLAS strongly rely on the concept of semantic integration (Brisson et al., 1993), (Böhms et al., 1994b). This means that the integration between different software applications is performed by means of a suite of referenc...

Representing knowledge with the use of ontology description languages offers several advantages arising from knowledge reusability, possibilities of carrying out reasoning processes and the use of existing concepts of knowledge integration. In this work we are going to present an environment for the integration of knowledge expressed in such a way. Guaranteeing knowledge integration is an important element during the development of the Semantic Web. Thanks to this, it is possible to obtain access to services which offer knowledge contained in various distributed databases associated with semantically described web portals. We will present the advantages of the multi-agent approach while solving this problem. Then, we will describe an example of its application in systems supporting company management knowledge in the process of constructing supply-chains.

Laser thermal lithography is a good alternative method for forming small pattern feature size by taking advantage of the structural-change threshold effect of thermal lithography materials. In this work, the heat-diffusion channels of laser thermal lithography are first analyzed, and then we propose to manipulate the heat-diffusion channels by inserting thermal conduction layers in between channels. Heat-flow direction can be changed from the in-plane to the out-of-plane of the thermal lithography layer, which causes the size of the structural-change threshold region to become much smaller than the focused laser spot itself; thus, nanoscale marks can be obtained. Samples designated as "glass substrate/thermal conduction layer/thermal lithography layer (100 nm)/thermal conduction layer" are designed and prepared. Chalcogenide phase-change materials are used as thermal lithography layer, and Si is used as thermal conduction layer to manipulate heat-diffusion channels. Laser ...

The physicochemical properties of 10% Co/silica-alumina cat.&& prepared by impregnation were studied by TPR, thermoanalysis and carbon monoxide adsorption. The temperature at which the catalyst was pretreated was found to have a great influence on its adsorption capacity for carbon monoxide. Both reduced and unreduced samples calcined in air at relatively high temperatures adsorbed carbon monoxide, but the reduced ones adsorbed much larger amounts. The adsorption capacity tended to increase with increasing pretreatment temperature. The character of carbon monoxide TPD profiles and the proportions of the individual adsorption forms were found to depend on tbe pretreatment temperature and the degree of cobalt reduction. Carbon monoxide was found to be adsorbed in three forms on species originating in cobalt-support interactions, metallic cobalt and on CosO,. Cakination in air was found to cause a decrease of both cobalt reduction and the activity in hydrocarbon synthesis. While the yield of gaseous products remained constant, that of the liquid ones decreased substantially with increasing pretreatment temperature, reaching a maximum value when the degree of cobalt reduction was ca. 40-50%. The average carbon number decreased with increasing cobalt reduction. The catalytic properties of Co/silica-alumina are more similar to those of Co/SiOz than of Co/A&O,, but Co/silicaalumina catalysts are less efficient in polymerization tban either Co/SiO, or Co/Al,Ox. The hypothesis, suggesting that the adsorption centres of weakly bonded carbon monoxide were involved in the production of liquid hydrocarbons and that the cobalt oxide species act dire&y in this synthesis, was confirmed.

The grass family Poaceae includes major crop genera like Triticum (wheat), H​ordeum (barley) and S​ecale (rye) in the subfamily Pooideae, and ​Saccharum (​sugarcane), ​Sorghum (sorghum) and Z​ea ​(maize) in the subfamily Panicoideae. Species from this family have been used for extensive hybridization experiments. No less than 59 valid nothogenera are listed in IPNI, yet dozens of intergeneric hybrids remain nameless.1 Notho- generic names are proposed here for eighteen intergeneric hybrids, including one tetrageneric hybrid, ten trigeneric hybrids and seven bigeneric hybrids. In addition, seven new combinations for nothospecies are proposed.
