Distance Similarity as a CBR Technique for Early Detection of Breast Cancer: An Egyptian Case Study

Case-based reasoning as a concept covers almost a lot of technologies and techniques including knowledge management, artificial intelligence, machine learning techniques as well as database technology. The usage of all these technologies can easily aid in early detection of breast cancer as well as help other decision makers take the right decision on time and all the times. Of the main hot topics nowadays concerning executive managers and decision makers is measuring the similarity between objects. For better performance most organizations are in need on semantic similarity and similarity measures. This article presents mathematically different distance metrics used for measuring the binary similarity between quantitative data within cases. The case study represents a quantitative data of breast cancer patients within Faculty of medicine Cairo University. The experimental results show that the squared chord distance yields better with a 96.76 % without normalization that correlate more closely with human assessments compared to other distance measures used in this study.
