Artykuł, na przykładzie systemu diagnostycznego, opartego na probabilistycznej bazie wiedzy i wnioskowaniu typu naive bayes, analizuje problem niedopasowania toku rozumowania systemu do ciągu myślowego eksperta i proponuje rozwiązanie oparte na rozszerzeniu podstawowej bazy wiedzy o specjalizowaną metawiedzę zależną dziedzinowo. Ocena rozwiązania problemu prezentowana jest na podstawie stworzonego systemu z bazą wiedzy, dedykowaną rozpoznawaniu typów nadciśnienia tętniczego.

EN

The article uses an example of a diagnostic system based on a probabilistic knowledge base and Naive Bayes Classifier inference, analyzing mismatch characteristic of the system’s reasoning and an expert’s reasoning to show the solution extending basic knowledge base with specialized, domain-dependent meta-knowledge. The evaluation of the solution is represented by the expert system dedicated to recognition of hypertension.

By-products of the combustion of coal (wastes) are often used for various types of construction (dwellings, roads, etc.). The legal regulations (The Ordinance of the Council of Ministers of 2 January 2007 “On the requirements for the content of natural radioactive isotopes of potassium K-40, radium Ra-226 and thorium Th-228 in raws and materials used in buildings for the residence of people and livestock, as well as in the industrial by-products used in the construction, and the control of the content of the aforementioned isotopes” – Law Gazette no. 4/2007 item 29) are in force in Poland. The regulations permit the possibility of utilization of raws and by-products basing upon the level of the natural radioactivity of the examined raws and materials. The article is a survey of the results obtained during the measurements of many types of raws and building materials for almost 30 years by the network of the laboratories in Poland. It is based upon the results stored in the database of the Central Laboratory for Radiological Protection (CLRP), Warsaw. The article tends to outline the radioactivity of the waste materials with respect to other raws and materials used in the construction industry. The article shows the possibilities for the use of by-products originating in the power stations and heat- and power stations (mainly ashes, slag and hinter) in the construction of dwellings and roads.
