A new similarity measure for objects that are represented by feature vectors of fixed dimension is introduced. It can simultaneously deal with numeric and symbolic features. Also, it can tolerate missing feature values. The similarity measure between two objects is described in terms of the similarity of their features. IF-THEN rules are being used to model the individual contribution of each feature to the global similarity measure between a pair of objects. The proposed similarity measure is based...

The purpose of this extended abstract is to summarize the report on the final achievements of the RusDML project, where this acronym stands for Russian Digital Mathematical Library. The initial phases of the project have been described in [Evstigneeva, G. A., Wegner, B.: O proekte sozdanija elektronnogo archiva russkich publikatsii po matematiki. Proceedings of LIBCOM 2002, Yershovo, November 2002.] and [Evstigneeva, G. A., Zemskov, A.: RusDML — a Russian-German project for establishing a digital...
