Case-Based Reasoning (CBR) paradigm is very close to the designer behavior during the conceptual design, and seems to be a fruitable computer aided-design approach if a library of design cases is available. The goal of this paper is to presents the general framework of a case-based retrieval system: REPRO, that supports chemical process design. The crucial(More)
One of the most important challenges in developing problem solving methods is to combine and synergistically utilize general and specific knowledge. This paper presents one possible way of performing this integration that might be generally described as follows: "To solve a problem, first try to use the conventional rule-based approach. If it does not work,(More)
Social networks have generated great expectations connected with their potential business value. The purpose of our research is to present that even a rudimentary application of data mining techniques can bring statistically significant improvement in marketing response accuracy throughout the virtual community. In our test the C&RT (classification and(More)
Business usage of online social networks is a natural result of their intense development in last years. The information about members of a given community can be treated as a basis of correct identification of their needs and as a result adjusting personalized marketing messages. In this study, we will discuss the classification and regression trees(More)
Data mining and/or case-based retrieval in object-oriented databases seems to be one of the crucial techniques in real-life engineering applications. The goal of this paper is to present the similarity measure for aggregation taxonomies. The computational complexity of the proposed measure is linear due to a domain-oriented matching heuristic. A detailed(More)
