I’m reading with great interest the paper

I’m happy to read they referenced our Tutorial on Cosine Similarity Measures. Their CBR-based search system combines a tf*IDF term vector scoring scheme and ontologies.

Their abstract follows:

In a dynamic industrial environment changes occur more and more rapidly, new machines, new staff when scaling up production and reduced staff when scaling down during a recession, staff with varying experience etc. This puts a high focus on experience reuse and sharing; much experience is lost during down-scaling and tied up in knowledge transfer/teaching during up-scaling. This is recognised as very costly for industry and reduces productivity and competitiveness. Condition Monitoring and diagnostics is such an area where lack on knowledge and mistakes can have severe consequences for a company’s long term existence. Maintenance staffs, technicians and engineers also gain much experience during their every day work, often during many years, but there are rarely any good processes for experience sharing and reuse inside the organisations. In this paper we present an experience sharing system based on case-based reasoning and limited natural language processing. The system is a tool for maintenance staff and engineers and enables efficient experience collection, reuse and sharing. The implemented prototype is web-based to promote access from any location and may be local or global enabling experience sharing openly or in clusters of collaborating companies. Case based reasoning has proven to be an efficient method to identify and reuse experience if the application domain has cases. Our target application domain has these features and there are plenty of cases valuable to reuse. We have validated this in close collaboration with maintenance engineers through field studies. The prototype developed shows promising features and will be tested in real industrial environments during 2007 and 2008.
