This function is mostly implemented by search agents that should help customers to find relevant product information. While these search functions are considered quite important by the online sellers, the quality of the retrieval results is miserable [7.4]. The key to enhancing search quality and, more generally, to approaching the vision of ...

We compare and contrast the two technologies (that are often confused) and show how they complement one-another. We then describe how they can be integrated in a single platform for reasoning from cases: the INRECA system.

We study integration along two dimensions: Integration of case-based methods with methods based on general domain knowledge, and integration of problem solving and incremental learning from experience. In the INRECA system, we perform case-based reasoning as well as TDIDT (Top-Down Induction of Decision Trees) classification by using the same data structure called the INRECA tree. We extract decision knowledge using a TDIDT algorithm to improve both the similarity assessment by determining optimal weights, and the speed of the overall system by inductive learning. The integrated system we implemented evolves smoothly along application development time from a pure case-based reasoning approach, where each particular case is a piece of knowledge, to a more inductive approach where some subsets of the cases are generalised into abstract knowledge. Our proposed approach is driven by the needs of a concrete pre-commercial system and real diagnostic applications. We evaluate the system on a database of insurance risk for cars and an application involving forestry management in Ireland.

The users should deliver requirements to the technical work packages to stimulate their thinking about how semantic technology should be developed to enhance the benefit of user applications. Another task was to test out the technology being developed. In particular, test out if and how the various technologies can be integrated. The final objective was to gain feedback from user trials, both regarding the functionality proposed and also regarding the modes of user interaction.

The main reason for this well-known deficit in e-commerce is that, unlike normal business situations, there is no intelligent support or assistance for the user on the Web. This is particularly evident in the selection of products/services or when navigating through the complex space of available product information. Current product-oriented database search facilities are widely used on the ...

Depending on the user (i.e. according to his/her declared profile), the task that has to be performed and the product that the user is interested in, the system generates personalized content on-demand. The system is applied to the management of service literature at a large international company that publishes vast amounts of technical documents.
