Effective online search for apparel products was investigated, and three systems were proposed, constructed and evaluated. The first system developed (Projection System) can project and display apparel products along a plane of two attributes chosen from a master list attributes relevant to apparel products. A second system (SOM System) was developed to resolve the problems found in “Projection System”. “SOM System” was created, based on a Self-Organized Map (SOM). In the last system (Improved SOM System), the arrangement of products in “SOM System” could be customized for each user and provided a better user experience with more effective results. Search experiments were conducted for these systems. The number apparel products displayed in “Projection System”, was much higher than that of a conventional search system, due to duplicate displays. While the display of “SOM System” seemed to be more effective, the arrangement of products was difficult to understand. In “Improved SOM System”, the issue of the arrangement of the products was resolved. With each new system, it was possible to find the desired product from a larger product offering, while also improving the quality of the search experience.
