The following paper presents the problem of classification (identification) elements in the internal structure of a technical object. This problem is directly linked with diagnostics and compilation of an expert data base. The basis of a process of grouping elements into classes is to make a diagnostic model of a given object in a form of a structure or set of basic elements of an object. In order to conduct the grouping of elements into subsets of s-th classes, the following paper compiles and presents analytical formulas and classification rules. Theoretical considerations presented in this paper are also verified using an engine control system as an example of a complex technical object.

W artykule zaprezentowano istotę budowania ekspertowych baz wiedzy z wykorzystaniem wnioskowania na podstawie prostych hipotez statystycznych. W tym celu określane jest prawdopodobieństwo sumy zdarzeń parami wykluczających się, tj. nie mających elementów wspólnych, musi być przy tym równe sumie prawdopodobieństw poszczególnych zdarzeń składowych. Prawdopodobieństwo całej przestrzeni {d}, czyli zdarzenia pewnego, musi być równe jedności w konsekwencji też, prawdopodobieństwo zdarzenia niemożliwego musi być równe zeru.

The paper presents the essence of building expert knowledge bases using inference on the basis of simple statistical hypotheses. For this purpose, the probability of total pairs of mutually exclusive events, i.e. not having the common elements must in this case be equal to the sum of the probabilities of the individual events of components. The probability of the entire space {d}, that is some events must be equal to unity, in consequence, also the probability of an event impossible to be equal to zero.

The paper focuses on technical aspects of creating a centralized expert knowledge base of vehicle repairs which is shared among its contributors. The proposed system is storing unstructured data gathered over the network from different sources such as workshops and authorized resellers. The novelty of the proposed system is to use a semantic web data store in form of OWL (Web Ontology Language) ontology in order to classify and explore the gathered data to significantly improve the process of resolution of challenging vehicle repair problems. Similar problems can be identified by using appropriate pattern recognition techniques and algorithms utilizing the Resource Description Framework (RDF) and its query language - SPARQL Protocol and RDF Query Language (SPARQL).
