CBR*Tools is an object-oriented software library for Case-Based Reasoning (CBR). It provides a basic reusable CBR framework that supports the development of CBR applications. It can be especially used for problems addressing behavorial situation retrieval and indexation.

CBR*Tools consists of three packages, namely, the core, time, and navigation package. The library is specified with the OMT method and written in Java. Click on the icon (on the right hand side), to get a full image of the system's main user interface.

• Plant nutrition control in collaboration with INRA Sophia-Antipolis.
  

• Navigation on internet : BROADWAY-V1 is a case-based system for supporting navigation on internet which is based on the http server called Jigsaw (W3C) (written in Java) and the CBR*Tools library. The first version of BROADWAY V1 will be avalaible soon.

• Argumentation in collective decision making (see ICCBR'97 on HERMES)

• Query reformulation in the context of a meta search engine in collaborationn with XRCE : BeCBKB

• Others applications for supporting Navigation inside a Web site (BROADWAY-PREDICT) )

Broadway V1 is a WWW browsing advisor reusing past navigations from a group of users : it follows a gorup of users during their navigations on the WWW (proxy-based architecture) and advise them by displaying a list of potentially relevant documents to visit next. Click on the icon (on the right hand side), to get a full image of the system's main user interface. Broadway uses case-based reasoning to reuse precise experiences derived from past navigations with a time-extended situation assessment : the advice are based mainly on similarity of ordered sequence of past accessed documents. In addition, the dynamic of the WWW is addresses in the reuse step and with a specific method for case forgetting.

Broadway V1 is written in Java using the Jigsaw proxy (W3C consortium) and CBR*Tools. It will be soon running on the Web. Click here for the slides of UK-CBR97 presentation.

Hermes An Argumentation System for the Web

Hermes is an Argumentation System for cooperative or non-cooperative type of discussions on the Web. It provides means of expressing and weighing individual arguments and preferences, in order to support or challenge the selection of a certain choice. The system supports defeasible and qualitative reasoning in the presence of ill-structured information. Argumentation is performed through a set of discourse acts which call a variety of procedures for the propagation of information in the corresponding discussion graph.

Hermes can be used by groups of agents to express their claims and judgements, aiming at informing or convincing, depending on the kind of the interaction. Unlike most current systems which merely provide threaded, hierarchical discussion forums (for an online survey click here), the system includes reasoning mechanisms that monitor the discussion, performing consistency checking and constantly updating the status of the argumentative discourse according to the proof standards involved.

Hermes is written in Java, and is running on the Web. Click on the icon (above), to get a full image of some user interfaces. A real application (on Preventive Medicine) will be starting in November '97, in the context of a project with EPFL, Switzerland.
