CBR is considered to be a methodology not a technology to use. Different applications and techniques can be used to find the similarities and make use of objects/cases within the case-library you have.
Such as CBR using fuzzy logic, using Rough-sets, similarity measures and maybe K-nearest neighbor. What about CBR using DB technology?
Do you mean database technology? Yes, most CBR systems, especially not intended for research purposes, uses some form of database. Many databases implement some form of similarity search such as the nearest neighbour algorithm.
Yes Tomas, but the problem with using database technology for
CBR is that databases retrieve using exact matches to the
queries. So the wildcards are used then. However the usage of some similarity searches as you mentioned it is much easier to make use of the DB technology within CBR systems.
But the problem here with the usage of DB technology within CBR is the retrieval as in DB the SQL statements maybe a bit harder for some cases. The usage of patterns and wild cards i mean... so in that case maybe the usage of AI and similarity measures could be much efficient in the retrieval process.
