Full textAbstract:
This thesis reports the research which led to the development of the P.R .O. Expert System Shell. The P.R.O . System is primarily, though not exclusively , designed for use in ecological domains. In the light of two specific expert systems, The RCS (River Conservation Status) and the Aquaculture Systems, which were developed as part of this research, a number of areas of importance have been identified. The most significant of these is the need to handle uncertainty effectively. The style of knowledge representation to be implemented also plays an important role. After consulting the relevant literature and the available microcomputer expert system shells, a number of ideas have been included in the P.R.O. System. The P.R.O . System is a backward chaining, production system based expert system shell. It embodies a simple but effective method of handling uncertainty. An important feature of this method is that it takes cognizance of the different relative importances of the conditions which need to be satisfied before a conclusion can be reached. The knowledge base consists of more than rules and questions. It also contains meta-knowledge, which is used by the inference engine. The P.R.O. System has been designed to be of practical use. Its strongest recommendations are therefore, that the two non-trivial systems which have been implemented in it, have been accepted by the experts and their peers as systems which produce good, accurate answers .KMBT_363

Many expert systems have been developed over the past decades. ProGrammar is a modest expert system shell that has been developed recently. It is built on top of the CProlog/UNIX* system running on a VAX† 11/750. ProGrammar is designed for processing and developing grammars. It can also be used as a knowledge base constructor for other fields besides grammars, a learning tool, a Prolog interpreter, and as a consulting system. ProGrammar is an interactive system meaning not only can the user query ProGrammar but ProGrammar also can question the user. The user is allowed to request an explanation from the ProGrammar on how the solution to the query was derived.Science, Faculty of

Electrical EngineeringM.S.E.
In a technology driven world, efforts are being made to make education/learning available to individuals at any time with no compromise in the quality of teaching/training. To make learning flexible, different techniques such as distributing learning material, uploading audio lectures on the web, and creating intelligent tutoring systems (ITS) are being used. The technique considered here is an adaptive ITS, a system that replicates the learning that occurs in a student teacher relationship. This thesis develops an adaptive intelligent tutoring system architecture prototype where the addition, modification and removal of educational material are relatively easy. The resulting software will take into account: the goals of the specific educational experience, the concepts to be covered, the preferred learning style of the student, measures to detect misuse of the system functionality, behavior based on the student's performance and the generation of hint sequences and feedback messages to improve learning gain. The system will accomplish these objectives by assessing the student's prior knowledge level, observing the actions performed by the student and by adapting to his/her learning abilities. The ITS will attempt to be more intelligent by performing some actions traditionally done by a human teacher - such as diagnosing misconceptions, identifying the most suitable learning style, stressing concepts that the student is finding difficult to understand, switching back to the learning material if the student shows no improvement after a set of trials. The system makes sure that the student is getting feedback where appropriate. Using this prototype system, the student will be tutored to acquire declarative knowledge. A problem based learning (PBL) approach will be used to strengthen the acquired knowledge by providing a high degree of personal attention to the student. To show how the prototype system works, an example of analysis of a control system problem using bode plot technique will be used to assist the student in using the technique to perform the stability analysis of an analog, linear, time-invariant control system problems and to recommend a controller to attain stability (if the system is not stable). Ideas of porting the system from standalone to web-based architecture and features required for collaborative learning will be discussed and an architecture for a web-based tutoring system for supporting multiple students enabling communication between students and sharing data among them will be proposed.

This thesis implemented a prototype of an expert system shell for support of engineering design activities in the way of logic programming. The development of the system is based on the theoretical framework for knowledge-based system design and the formal modeling concepts. Under the above methodologies, two knowledge representations, production rule system and system entity structure, are incorporated into the knowledge base for figuring design structures. Here the production system scheme is employed for synthesis of design models represented in the system entity structure. The whole system is coded in Turbo Prolog and a specific domain knowledge, namely a local area network, is currently used as a testbed environment.

Full textAbstract:
Spatial decision making is a process of providing an effective solution for a problem that encompasses semi-structured spatial data. It is a challenging task which involves various factors to consider. For example, in order to build a new industry, an appropriate site must be selected for which several factors have to be taken into consideration. Some of the factors, which can affect the decision in this particular case, are air pollution, noise pollution, and distance from living areas, which makes the decision difficult. The geographic information systems (GIS) and the expert systems (ES) have many advantages in solving problems in their prospective areas. Integrating these two systems will benefit in solving spatial decision making problems. In the past, many researchers have proposed integrating systems which extracts the data from the GIS and saves it in the database for decision making. Most of the frameworks which have been developed were system dependent and are not properly structured. So it is difficult to search the data. This thesis proposes a framework which extracts the GIS data and processes it with the help of ES decision making capabilities to solve the spatial decision making problem. This framework is named GeoFilter. This research classifies various types of mechanisms that can be used to integrate these two systems.

Full textAbstract:
"A Single Function Agent (SiFA) is a software agent, with only one function, one point of view, and one target object on which to act. For example, an agent might be a critic (function) of material (target) from the point of view of cost. This research investigates the possibilities and implications of the SiFA concept, and analyzes the definition language, negotiation language and negotiation strategies of the agents. After defining a domain-independent set of agent types we investigated negotiation, analyzing which pairs/groups of agents have reason to communicate, and what the information passed between them should be, as well as what knowledge was needed to support the negotiation. A library for the CLIPS expert system shell was built, which allows development of SiFA based expert systems from domain independent templates. We will present two such systems, one as implemented for the domain of ceramic component material selection and the other (in development) for simple sailboat design. The effect of negotiation on the design process and the results are discussed, as well as directions for future research into SiFAs."

Full textAbstract:
The Generalized Constraint Language (GCL), introduced by Zadeh, is the essence of Computing with Words (CW). It provides an genda to represent the meaning of imprecise words and phrases in natural language and introduces advanced techniques to perform reasoning on imprecise knowledge. Despite its fundamental role, the definition of GCL has remained informal since its introduction by Zadeh and, to our knowledge, no attempt has been made to formalize GCL or to build a working GCL deduction system. In this dissertation, two main interrelated objectives are pursued: First, the syntax and semantics of GCL are formalized in a logical setting. The notion of soundness of a GCL argument is defined and Zadeh's inference rules are proven sound in the defined language. Second, a CW Expert System Shell (CWSHELL) is implemented for the realization of a GCL deduction system. The CWSHELL software allows users to express their knowledge in terms of GCL formulas and pose queries to a GCL knowledge base. The richness of GCL language allows CWSHELL to greatly surpass current fuzzy logic expert systems both in its knowledge representation and reasoning capabilities. While many available fuzzy logic toolboxes can only represent knowledge in terms of fuzzy-if-then rules, CWShell goes beyond simple fuzzy conditional statements and performs a chain of reasoning on complex fuzzy propositions containing generalized constraints, fuzzy arithmetic expressions, fuzzy quantifiers, and fuzzy relations. To explore the application of CWSHELL, a realistic case study is developed to compute the auto insurance premium based on an imprecise knowledge base. The alpha version of CWSHELL along with the case study and documentation is available for download at http://cwjess.cs.siu.edu/.

The expert systems are computational tools built from argument of strong methods in artificial intelligence. This argument states that the resolution of complex problems is only possible when specific knowledge of the nature of the problem to be solved is known. The construction of expert systems in addition to be a very complex task involves a precious expenditure of time. Due to this, there are tolls called Shell that allow rapid prototyping of an expert system, demonstrating or not the viability of a Integral System construction. In this work, the main concern was to develop a Shell that was used with priority, but not exclusively, to diagnosis applications in medicine. In this sense, the system has been provided with the ability to handle linguistic data, data like image and numeric interval data (expressed by ranges of values: a x b). The possibility of working with numerical interval data and with multivalued variables is the main difference between Shell proposed in this work compared to other publications found in literature. In order to be possible to deal with interval data, a specific inference algorithm that incorporates an unification algorithm was developed. It has been given to the system the treatment of uncertainty through certainty factors. There is the possibility of working with multiples targets simultaneously. In the results, an original system was developed for atherosclerosis diagnostics that uses rules with interval variables and a system for AIDS treatment that uses multivalued variables. Moreover, the uncertainty treatment in the Shell proposed is compared with the uncertainty treatment in two other systems nationally developed. As a conclusion, the great application of the proposed system is highlighted, which allows the diagnosis in areas so varied that ranges from radiology to laboratory diagnosis.
Os sistemas especialistas são ferramentas computacionais construídas a partir do argumento dos métodos fortes em inteligência artificial. Esse argumento afirma que a resolução de problemas complexos só é possível quando se dispõem de conhecimentos específicos sobre a natureza do problema a ser resolvido. A construção dos sistemas especialistas, além de ser uma tarefa assaz complexa, envolve o dispêndio de tempo. Devido a isso, dispõe-se de ferramentas denominadas de Núcleo de Sistemas Especialistas (NSE) ou Shell, que permitem a prototipagem rápida de um Sistema Especialista, demonstrando ou não a viabilidade da construção de um Sistema Integral. Neste trabalho, a principal preocupação foi desenvolver um NSE que fosse utilizado de forma prioritária, mas não exclusiva, para aplicações diagnósticas em medicina. Nesse sentido, dotou-se o sistema da capacidade de lidar com dados literais, dados tipo imagem e dados numéricos intervalares (dados expressos por meio de faixas de valores: a x b). A possibilidade de trabalhar com dados numéricos intervalares e com variáveis multivaloradas é o principal diferencial entre o NSE proposto neste trabalho em relação a outras publicações. Para tornar possível o tratamento de dados intervalares, desenvolveu-se um algoritmo de inferência próprio que incorpora algoritmo de unificação também original. Dotou-se o sistema de um tratamento da incerteza por meio de fatores de certeza. Existe a possibilidade de trabalhar-se com múltiplas metas simultaneamente. Nos resultados, desenvolveu-se um sistema original para diagnóstico da aterosclerose que utiliza regras com variáveis intervalares, um sistema para tratamento da AIDS que utiliza variáveis multivaloradas. Compara-se, outrossim, o tratamento da incerteza no NSE proposto com o tratamento da incerteza em outros dois sistemas desenvolvidos nacionalmente. Como conclusão, destaca-se o amplo espectro de aplicações do sistema proposto, que permite o diagnóstico em áreas tão variadas que vão desde a radiologia à diagnóstico com dados laboratoriais.

Full textAbstract:
The goal of this dissertation is to organize a probabilistic expert system with use of
the Shell Spirit in order to evaluate the default risk of borrowers in a financial
institution or minimize the risk that it represents. The study was limited to private
individuals, since the variables used to analyse the risk in the concession of credit to
legal entities are different, and also to the fact that this area is less explored by
academics. The applied methodology was inserted in the context of a quantitative
empirical research, which aimed to bring the model developed as close to reality as
possible. However, in this step it was necessary to collect inside information of the
institution used to study, referring to risk analysis, credit policies, profile of borrowers,
and also to extract knowledge from the experts with the purpose of selecting the
relevant variables for the system and to make the interaction of these when
composing rules along with the definition of their weights. Consecutive to the
conclusion of the model, tests occurred with some favorable situations and/or
unfavorable to the granting of credit, considering that in this phase were instantiated
the pertinent variables to each situation at hand. The main idea of the system is to
manage and reduce the credit risk of bank institutions, for SPIRIT, an expert system
is able to work with uncertainties and manipulates data, being fed with information
that indicates the no default probability. The results obtained with the tests were
satisfactory as they were able to identify the probability of a borrower turn out to be a
no default or minimize the risk, even before the credit was released.O objetivo desta dissertação é estruturar um sistema especialista probabilístico com utilização da Shell Spirit para avaliar o risco de inadimplência de tomadores de crédito em uma instituição financeira ou de reduzir o risco que ele representa. O estudo foi limitado a pessoas físicas, uma vez que, as variáveis utilizadas para a análise de risco na concessão de créditos se diferem das pessoas jurídicas e, também, pelo fato de esta ser uma área menos explorada pelos acadêmicos. A metodologia aplicada foi inserida no contexto de uma pesquisa empírica quantitativa, na qual se buscou aproximar o máximo possível o modelo elaborado à realidade. Contudo, nesta etapa foi necessário coletar informações internas da instituição utilizada para o estudo, referentes à análise de riscos, políticas de crédito, perfis de tomadores, bem como extrair conhecimentos de especialistas com a finalidade de selecionar as variáveis relevantes para o sistema e de fazer a interação destas ao compor regras juntamente com a definição dos seus pesos. Consecutivo à conclusão do modelo, ocorreram testes de algumas situações favoráveis e/ou desfavoráveis a concessão de créditos, considerando que nesta fase foram instanciadas as variáveis pertinentes a cada situação em questão. O sistema é capaz de gerenciar e reduzir os riscos de crédito de instituição bancária, pois o SPIRIT trabalha com incertezas e manipula dados, sendo alimentado com informações que indiquem a probabilidade de inadimplência não . Os resultados obtidos com os testes foram satisfatórios à medida que estes possibilitaram identificar a probabilidade de um tomador de crédito vir a torna-se um não inadimplente ou de reduzir o risco, antes mesmo da liberação do crédito.

Brazil is among the most entrepreneurial countries in the world, but the mortality rates of the small companies are high. With very fierce competition levels among the companies it is necessary for the entrepreneurs to know their competences and possibilities to set up with
success. In the ambience of small businesses the owners and the companies are closely linked, making it impossible to evaluate the causes of successes or insuccesses of the business without diving into the entrepreneur s personal life. These small companies differ from great corporations with shareholders and executives because these roles are played by the same person. To have an appropriate profile it is necessary to know them in aspects such as: personal organization, networking, financial availability, academic degree, field knowledge, previous experiences, motivation, health and time available, among other variables defined by
experts as important for the success of the business. Using Shell Spirit enabled to quantify variables, establish rules and develop a probabilistic expert system of success assessment in new business opening. The results that represent the tendency of success of the future
business analyzed were segmented in scales ranging from to 98% in average. The tool is flexible and allows the individual assessment of the entrepreneur and each individual impacts of helps them to make decisions in the business plan elaboration.O Brasil está entre os países mais empreendedores do mundo, mas as taxas de mortalidade dos pequenos negócios são altas. Com intensos níveis de competição entre as empresas, cada vez mais é necessário os empreendedores conhecerem suas competências e possibilidades para se estabelecer com sucesso. No ambiente dos pequenos negócios os donos e as empresas estão umbilicalmente ligados, sendo impossível avaliar as causas de sucesso ou insucesso dos negócios sem fazer um mergulho na vida pessoal do empreendedor. Diferentemente das grandes corporações, com acionistas e gestores profissionais, nas pequenas empresas esses papéis são exercidos pela mesma pessoa. Para ter um perfil adequado é necessário conhecê-los em aspectos como organização pessoal, rede de contatos, disponibilidade financeira, formação acadêmica, conhecimentos do setor, experiências anteriores, motivação, saúde e tempo disponível, entre outras variáveis definidas por especialistas como importantes para o sucesso nos negócios. Através do uso da Shell Spirit foi possível quantificar variáveis, estabelecer regras e desenvolver um sistema especialista probabilístico de avaliação de sucesso na abertura de novos negócios. Os resultados, que representam as tendências de sucesso dos futuros negócios analisados, foram segmentados em escalas, variando de 1% até 98% em média. A ferramenta é flexível e além de permitir a avaliação individual do empreendedor e quais os impactos individuais de cada variável no resultado final, auxilia-os na tomada de decisão quando da elaboração do plano de negócios.

Full textAbstract:
Digital educational technology is capable of contributing supplementary strategies that can be used to address various educational challenges faced by higher education. Foremost among these challenges is the widespread lack of academic preparedness of students who enter South African higher education institutions. The legacy of Apartheid, teachers' poor domain knowledge and command of the language of instruction, together with a lack of commitment to the cognitive development of learners are some of the reasons why students have not developed the cognitive skills required to engage in meaningful learning. Meaningful learning requires a high level of conceptual engagement and development. To assist in the learning process, educators must focus on student learning rather than on the instructor and the technology used in the instruction. A powerful means of supporting meaningful learning is through a process of model building. Computer technology can effectively be used to facilitate the building of conceptual models. By encouraging students to use computer technology to build models that represent their personal understanding, the students are performing the role of designer and the technology is used as a cognitive tool. Using digital technology as a cognitive tool allows students to engage in critical thinking and higher-order learning. An expert system shell is one way in which technology can be used as a cognitive tool. When students build expert systems they are required to demonstrate the reasoning of an expert and to exhibit an understanding of causal relationships and procedural knowledge. There is very little evidence of research concerning the application of expert systems as a cognitive tool in education. The primary aim of this study is to formulate design principles in the form of conjectures and principles related to a learning environment that uses technology as a cognitive tool in the form of an expert system shell to promote higher-order thinking skills. The second aim of this study is to explore the experiences of students who are exposed to a learning environment based on the conjectures and principles formulated during the design phase of the research. The conjectures and principles formulated during this study are expressed in terms of the characteristics, procedures and arguments associated with a learning environment that uses technology in the form of an expert system shell to facilitate higher-order thinking. These conjectures and principles were separated into seven interrelated clusters that can be summarised as follows: - initial exposure;
- guided discovery learning;
- designing the expert system on paper;
- creating domain awareness;
- linking conceptual understanding to a representation of that understanding;
- hands-on development; and
- problem engagement.

Full textAbstract:
Dans cette thèse, nous fournissons un examen complet des technologies du Web sémantique et de leurs utilités dans le contexte actuel des petites et moyennes entreprises (PME). Les approches traditionnelles d'intégration des entreprises favorisent essentiellement les grandes entités. Les obligations contractuelles fortes sur les PME, mais en même temps leur volonté de garder leurs compétences individuelles, et ce, dans un environnement limitant leur choix, les obligent à prendre des décisions stratégiques et de conclure des accords sur le long terme avec leurs partenaires, limitant ainsi leur flexibilité aux fluctuations du marché. Nous proposons, donc, une approche ontologique basée sur Web sémantique pour l'intégration de l'information ainsi que des ressources matérielles de l'entreprise distribuée. Cette approche, basée sur le Web, agit comme un système d'aide à la décision pour utiliser des ressources de meilleure qualité ainsi que pour l'intégration de l'information distribuée. Les travaux relatifs à l'ontologie web, pour l'intégration d'information ne sont pas nouveaux, mais l'approche proposée par nous est une valeur ajoutée pour l'entreprise distribuée. De plus, nous avons également proposé l'ontologie Web sémantique comme un système de configuration pour gérer les ressources distribuées de l'entreprise virtuelle. Puis, nous avons modélisé l'ontologie OWL-DL en nous basant sur la sémantique de la norme ISA-95, relative à l'intégration d'entreprises industrielles. Ensuite, nous utilisons cet artefact ontologique comme un artefact de configuration permettant de gérer le matériel de l'entreprise virtuelle distribuée ainsi que les ressources matérielles. C'est la proposition principale de cette thèse : utiliser l'ontologie Web sémantique comme un système d'aide à la décision pour la configuration de l'utilisation des ressourcesIn this thesis, we have provided a complete review of the semantic web technologies and their corresponding utility in the current environment for small to medium sized enterprise (MSE). The traditional approaches to enterprise integration favour large enterprise entities and force contractual limitations on smaller partners, but at the same time the pressure to guard the individual enterprise competence is ever increasing, the distributed enterprise (MSE) in such an environment have limited number of choices, which forces them to make strategic decisions and enter into a long term agreements with their partners and this limits their flexibility to the market changes. We, in this thesis, propose a semantic web based ontology approach for integrating the information as well as physical resource of the distributed enterprise. This web based approach acts as a decision support for better resources utility as well as distributed information integration. The work related to web ontology?s for information integration is not new, but the approach proposed in this thesis for distributed enterprise is an added value. Similarly, we have also proposed semantic web ontology as a configuration system to manage the distributed resources of the virtual enterprise, for this we have modelled OWL-DL ontology on the semantic of the industrial integration standard ISA-95, and subsequently used this ontology artefact as a configuration artefact to manage the distributed virtual enterprise material and equipment resources this is the main proposition of the thesis of utilizing semantic web ontology as resource configuration decision support

Full textAbstract:
Recent years hve seen the increasing use of expert systems and expert system shells in industry and commerce. However, there has been little use of the technology in schools and colleges, partly due to dissatisfaction with the available software. This thesis describes the design, implementation and evaluation of an expert system shell for use in education. An initial evaluation was carried out to establish some criteria for the design of the new shell. This comprised an evaluation of expert system shells by experienced teachers; an evaluation of several expert system shells by the author; and a case-study visit to a school Computer Studies department. The teachers were also asked for their views on the possible uses of shells in the classroom. An expert system shell was designed and implemented as a result of this evalation. This has an environment for building knowledge bases; an environment for consulting knowledge bases; a knowledge representation language allowing separation of domain and problem solving knowledge; and three supplementarty tools. The most important of these is an explanation tool, which allows exploration of the domain knowledge in a knowledge base. In response to posed questions, the tool can produce domain-based explanations using a domain-independent generation technique, and each explanation can be explored further through relevant follow-up questions. This tool provides a means whereby users can learn about the domain of the knowledge base being explored. An evaluation of this shell by teachers with previous experience of expert system shells suggests that it has the potential for use throughout the school curriculum as an educational medium.

This thesis uses the technology of artificial intelligence and expert system to build an expert system shell suitable for configuration design of mechanical systems. First, the composition relationships between system components are obtained through applying a decomposition process on the mechanical system, and these relationships are represented in a semantic network. Then, the design data of system components was modeled by the frame-based knowledge representation method. Because of the inheritance nature of the frame-based representation method, hierarchical relationships between components can be established. In order to do the actual design work, such as selection of a component from its component library, satisfying design requirements and determination of design parameters, a constraint representation algorithm and a constraint satisfaction process was developed. After the configuration design of a mechanical system is completed, a 3D solid model of the system will be constructed by an interface program between the developed expert system and the AutoCAD software. In order to prove the functions of this expert system shell, several commonly used mechanical components and systems are chosen as examples and results are great.

A dissertation submitted to the Faculty of Engineering, University of the Witwatersrand,
Johannesburg, in fulfilment of the requirements for the degree of Master of
Science in EngineeringA multi-layered expert system shell that specifically addresses real-time issues is designed and implemented. The architecture of this expert system shell supports the concepts of parallelism, concurrent computation and competitive reasoning in that it allows several alternatives to be explored simultaneously. An inference engine driven by a hybrid of forward and backward chanining methods is used to achieve real-time response, and certainty factors are used for uncertainty management. Real-time responsiveness is improved by allowing the coexistence of procedural and declarative knowledge within the same system. A test bed that was set up in order to investigate the performance of the implemented shell is described. It was found in the performance analysis that the proposed system meets the real-time requirements as specified in this research.

This thesis uses the concepts of Object-Oriented Methodology to develop an expert system shell for assembly design of mechanical systems. First, an object-oriented knowledge representation method is defined for representing the necessary design data and design parameters for a mechanical assembly, then the connective relationships between mechanical components are established by the concepts of semantic network. A constraint representation format is developed to represent the design constraints between components of the system. Finally, an expert system shell is developed for operation and management of the knowledge base. After the initial data for the system are specified, assembly parameters for all feasible solutions can be found through the inference engine by satisfying the design constraint. The solid model of the assembly design for any feasible solution can be automatically generated in AutoCAD software. The detail design process of some demonstrative examples are included to show the capability of the developed expert system shell. The design process of two real machines are also included. It shows that the developed expert system shell can handle the assembly design easily and effectively.

Full textAbstract:
Σκοπός της παρούσας εργασίας ήταν η δημιουργία ενός ευφυούς συστήματος για τη διάγνωση νοσημάτων του προστάτη αδένα με βάση σημεία και συμπτώματα που διαπιστώνονται σε έναν ασθενή όπως καταγράφονται κατά την κλινική του εξέταση.
Τα βασικά σημεία της εργασίας είναι τα εξής: αρχικά παράγεται το μοντέλο της διαγνωστικής στρατηγικής που ακολουθείται για τη διάγνωση των συγκεκριμένων παθήσεων και στη συνέχεια γίνεται εκμαίευση της διαγνωστικής γνώσης από ειδικούς ή/και από εμπειρικά δεδομένα. Η διαδικασία και η γνώση αναπαρίστανται με χρήση υβριδικών μεθόδων αναπαράστασης και με τη χρήση ασάφειας ή/και αβεβαιότητας, η οποία είναι εγγενής σε τέτοια διαγνωστικά συστήματα.
Το σύστημα αναπτύχθηκε με τέτοια εργαλεία που δίνουν την δυνατότητα στέγασής του σε ιστότοπο ώστε να χρησιμοποιηθεί ως ειδικός συμβουλευτικός οδηγός από ενδιαφερομένους μη ειδικούς ιατρούς & από ασθενείς καθώς και από φοιτητές υγειονομικών σχολών για εκπαιδευτική χρήση. Το σύστημα περιέχει γνώση εμπειρογνωμόνων σε συνδυασμό με στοιχεία πλούσιας βιβλιογραφικής αναζήτησης και μελέτης. Τέλος πραγματοποιήθηκε επικύρωση των αποτελεσμάτων μέσα από μια τυχαιοποιημένη κλινική έρευνα.
Η υλοποίηση του συστήματος μας στηρίζεται σε ένα ειδικό κέλυφος δημιουργίας ευφυών συστημάτων και σε εργαλεία μεθόδων μηχανικής μάθησης. Επίσης, υλοποιούνται δύο εκδοχές (Hirofilos Ι & ΙΙ) και γίνεται σύγκριση των απο-τελεσμάτων. Αναγνωρίστηκε η σαφής υπεροχή του Hirofilos ΙΙ που αναπτυχθηκε με σύστημα μηχανικής εκμάθησης και με δυνατότητα διαχρονικής αναβάθμισης.During making this project our concern was the creation of a new expert system for diagnosis prostate disease depending on the clinical status of a patient as these are identified during medical examination. The main points were as follows: First has been constructed a diagnosis process model which was followed by the diagnosis for the most common prostate diseases. Secondly was implemented extracting of the medical knowledge based on specialists or/and experimental data. The whole process and the medical Knowledge will be developed using hybrid methods of representation and having the partcipation of such saying fuzziness or inaccuracy, that is innate in that kind of intelligent decision-support. The new intelligent system is already accommodated on a hospital server and is used as a decision-support system, as well as an e-learning platform for medical students. For the implementation of the new system have been used an expert system shell and knowledge engineering tools.
