Applications using COLIBRI

Using ‘Case based reasoning’ for the solution of water stress problems.
Aquastress (6th European Frame Project)
“…An application of Case Based Reasoning (CBR) for the solution of water stress problems. The (software) application is developed in the framework of Aquastress project that is focused on developing interdisciplinary methodologies and tools, enabling actors to mitigate water stress problems. In Europe, various regions may encounter similar kinds of water stress due to among others comparable physiographic conditions, land use functions and/or socio-economic conditions.”
“The Aquastress CBR software application is developed in cooperation with Good Heavens company and it uses a JColibri CBR Framework provided by Group of AI applications, University of Madrid.”

Ambient-Intelligent Interactive Monitoring System for Energy Use Optimisation in Manufacturing SMEs
AmI-MoSES Project (7th European Frame Project)
“The AmI-MoSES project is about realising an innovative, beyond the state-of-the-art solution for Energy Efficiency optimisation in manufacturing companies. The solution is based on (…) Knowledge Management technologies to realise a decision support system as add-on to the currently used Energy Management Systems.”
“The Knowledge Management Service was realized using free software JColibri. The CBR core service itself is used in the Service platform directly as a part of the problem solving ASCS and indirectly in the EE services for Online Diagnostics, Continuous Improvements and Ramp-up support.” AmI-MoSES_D7.6_EP_Platform_Public_v1.0.pdf

Open Negotiation Environment
One Project (6th European Frame Project)
“The main objective of the ONE project is to enrich Digital Business Ecosystems with an open, decentralised negotiation environment and enabling tools that will allow organisations to create contract agreements for supplying complex, integrated services as a virtual organisation/coalition. (…) Within the ONE framework, one of the core components is the Recommender System (RS). The RS plays a key role in supporting users during negotiation processes with recommendations on how best to conduct a given negotiation. (…) A recommendation function based on the Case-Based Reasoning methodology consists of three different parts: (i) Third-Party Framework. This is the external Case-Based Reasoning system, such as jCOLIBRI. It has its own CBR Models and API. (…)”

BULCHINO: an Intelligent Web-based Catalogue for electronic presentation of culture-historical heritage of Bulgaria.
E-Commerce Laboratory (ECL), University of Plovdiv, Bulgaria.

  • CBR-Based Search in BULCHINO Catalogue
    “(…) the Framework jCOLIBRI is adapted and utilized for the configuration of a CBR-based application in the particular domain BULCHINO Catalogue. (…) Since BULCHINO Catalogue is integrated in J2EE environment and has distributed architecture, we think that the framework could be easily adapted for the development of PersonExample Module”
  • An Ontology Based CBR Architecture for Knowledge Management in BULCHINO Catalogue
    “jCOLIBRI enhances the other CBR shells: CAT-CBR, CBR*Tools, IUCBRF, Orenge in several aspects: availability (open source framework), implementation (the Java implementation is one of our main requirements with respect to the easy integration in the BULCHINO system which is implemented in J2EE environment), GUI (the provided graphical tools facilitate the system design). Another decision criterion for our choice is connected with the fact that jCOLIBRI affords the opportunity to incorporate ontology in the CBR application to use it for case representation and content-based reasoning methods to assess the similarity between them.”
