When applying CBR for Electronic Commerce, the adaptation capabilities of CBR can be used for product customization. Most adaptation techniques suffer from the problem that they require a large knowledge acquisition effort which leads to problems in the rapidly changing E-Commerce scenario. In this paper we present a new approach to adaptation that is particularly suited to Electronic Commerce applications.

Customers of electronic shops find more and more support for the search and selection of products in the sales systems. Unfortunately, most of the shops do not provide additional support with parameterizable or configurable products. Such products could be further customized. One of the major problems most customization techniques suffer from is that they require large knowledge acquisition effort, which leads to problems in the rapidly changing e-Commerce scenario. In this paper, we present a new approach to customization that is particularly suited to e-Commerce applications. It assumes that products can be structured hierarchically into subcomponents. Customization is achieved by incrementally replacing unsuitable sub-components through recursively finding best-matching alternative sub-components, using Case-Based Reasoning technology for this search process. The presented approach avoids huge portions of the knowledge acquisition effort. The approach is implemented as a prototypica...

This paper presents a new approach for compositional adaptation and investigates its applicability for a tutoring library system. Compositional adaptation has been applied in the designed tutoring library system, since many cases at the same time can be similar to the user request, and through this way, the possibility will exist to combine the corresponding solutions (books' chapters in our case) in an efficient way yielding the final solution. Each case in the library itself is represented in terms of a presuggested set of chapters from different books in general. Such an approach to suggesting solution to the user provides a suitable ground to take into account a variety of factors such as current knowledge level and the desired status of knowledge which have not been considered sufficiently in standard library systems.

Current CBR applications for sales support in electronic commerce are limited to fixed, unchangeable products. In order to support sales support for configurable products, customization of base products must be supported as well. For this purpose, an interactive operator-based transformational adaptation approach from CBR can be applied and realized as a flexible client-server architecture for business-to-business as well as business-to-consumer applications. Such an approach is currently realized as part of the ESPRIT project WEBSELL.

. Nowadays, many configurable products and services are sold via web.

Abstract. We present a form of case-based reuse conducive to the cooperation of multiple CBR agents in problem solving. First, we present a form of constructive adaptation for configuration tasks with compositional cases. We then introduce CoopCA, a multi-agent constructive adaptation technique for case reuse. The agents suggest possible components to be added to the ongoing configuration problem, allowing an open, distributed process where components used in cases of different agents are pooled together in a principled way. Moreover, the agents can use their case base to inform about a similarity-based likelihood that the suggested component will be adequate for the current problem. We illustrate CoopCA by applying it to the task of agent team formation 1. 1

We present a Personalized Health Information Generation and Delivery System that leverages case based reasoning techniques to dynamically author a Personalized Health Information Package based on an individual's current health profile. The work features a compositional adaptation approach, whereby relevant health information elements from the solution component of multiple similar past cases are carefully selected and systematically combined to yield a new personalized health information package. We have implemented a generic Java-based case based reasoning engine that applies a novel compositional adaptation algorithm to author a HTML-based personalized health information package that can be emailed to users.

. Existing electronic shops based on CBR technology allow customers to search for adequate products by only specifying the attributes for the products in a fuzzy way. Unfortunately, most electronic shops do not further support customers after the retrieval step. However, especially configurable products could be customized at this stage. Based on the approach of interactive adaptation operators, we present a flexible system architecture for a customization module which can be easily integrated in electronic shops. Our approach of a modular adaptation concept is implemented and currently tested within the ESPRIT project WEBSELL 1 1 Introduction CBR technology becomes more and more important in e Commerce scenarios, especially in online shops on the Internet or CDR OM catalogs. CBR systems can be used to support electronic sales intelligently, which can be seen by the growing number of CBR applications on the Internet (e.g., real estates 2 ,last minute flights 3 ,...

The number of electronic catalogs has grown rapidly during the past few years. Most of these catalogs use standard databases for storing and retrieving product information. Using ordinary databases for product catalogs, however, has the major drawback that it is often very difficult to find the products desired: very often, the database does not return a matching product at all or it returns many products that have to be examined manually. To overcome this problem, we propose the use of Case-Based Reasoning (CBR) techniques as an approach to requirement-oriented retrieval of products. CBR incorporates product knowledge into the database by means of a similarity measure. Recently, a number of commercial electronic catalogs based on CBR have been realized. We take a closer look at Analog Devices' on-line catalog of operational amplifiers, which helps an engineer to find a suitable amplifier for her specific requirements. 1 Introduction The number of electronic catalogs -- especially on...
