Resumo:
The Data Mining field has received great attention lately, due to the increasing amount of data stored by companies and institutions. A great number of Data Mining methods have been proposed so far, which is good but sometimes leads to confusion. This dissertation investigates the performance of many different methods and techniques of Data Mining used to model and solve Marketing problems. The goal of this research was to look for and study some data mining methods, compare them, and try to integrate them to solve Marketing problems involving clustering and classification tasks. This research can be divided in four stages: a study of the process of Knowledge Discovery in Databases (KDD); a study about Marketing problems involving clustering and classification; a study of some methods and techniques of Statistics and Computational Intelligence that could be used to solve some of those problems; and case studies. On the first stage of the research, the different tasks (clustering, classification, modeling, etc) and phases (data cleansing, data selection, data transformation, Data Mining, etc) of a KDD process were studied in detail. The second stage involved a study of the main concepts of Marketing and Database Marketing and their relation to the KDD process. The most common types of problems in the field were studied and, among them, two were selected to be furthered analyzed as case studies. One case was related to Direct Marketing and the other to Market Segmentation. These two cases were chosen because they were complex enough and it was possible to find a company to provide data to the problem and access to their marketing department. On the third stage, many different methods for clustering and classification were studied and compared. Among those methods, there were: Multilayer Perceptrons, Self Organizing Maps, Fuzzy C-Means, K-Means, Neuro-Fuzzy systems, Decision Trees, Hierarquical Clustering Methods, Logistic Regression, Fisher`s Linear Discriminants, etc Finally, on the last stage, all the methods and techniques studied were put together to solve the two case studies proposed earlier. Once they were solved, their solutions were submitted to the Marketing Department of the company who provided the data, so that they could validate the results in the context of their business. The case studies were able to show the large potential of applicability of the methods and techniques studied on problems of Market Segmentation and Direct Marketing. Without employing those methods, it would be very hard or even impossible to solve those problems. The case studies also helped verify the very important role of the data pre-processing phase on the KDD process. Many challenges persist in the data mining field. One could mention, for example, the difficulty to model non-linear data and to manipulate larges amounts of data. These and many other challenges provide a vast field of research to be done in the next years.
