Construction of online catalog topologies using decision trees

Organization of a Web site is important to help users get the most out of the site. A good Web site should help visitors find the information they want easily. Visitors typically find information by searching for selected terms of interest or by following links from one Web page to another. The first approach is more useful if the visitor knows exactly what he is seeking, while the second approach is useful when the visitor has less of a preconceived notion about what he wants. The organization of a Web site is especially important in the latter case. Traditionally, Web site organization is done by hand. In this paper, we introduce the problem of automatic Web site construction and propose a solution for solving a major step of the problem based on decision tree algorithms. The solution is found to be useful in automatic construction of product catalogs.published_or_final_versio

Automatic Construction of Online Catalog Topologies Using Decision Trees

Measuring whole field strain over two-dimensional fields is important in NDE, especially if such measurements permit the qualitative representation of data, allowing for the imaging and detection of defects. A number of techniques have been used to achieve this, including moire interferometry, holographic interferometry and speckle interferometry. Although all of these methods can provide qualitative images representative of the deformation field, they share the disadvantage of being difficult to analyze quantitatively. This is due to the need for the interpretation of the fringes generated by these techniques, which is time consuming and requires highly skilled practitioners. Additionally, even though these experimental techniques provide a whole-field qualitative appraisal of a two-dimensional field, quantitative data are obtained only at discrete points over the areas of interest
