Abstract

We discuss descriptors and templates within relational information systems. We provide examples how to use attribute-specific similarity measures to equip standard information systems with relational structures. We introduce new types of descriptors, which take an advantage of available relations, forming cliques or stars of inter-related attribute values. We also show how to build relational templates from collections of such relational descriptors. We illustrate the proposed framework with possible applications.
