Querying Relational Concept Lattices
Navigating a Concept Lattice Family w.r.t a Query Introduction Relational Concept Analysis (RCA) constructs conceptual abstractions from a relational context family (RCF). An RCF is sets of objects described by both own properties and inter-object links. It generates several lattices that are connected via relational attributes. Navigating such interrelated lattice family in order to find conce...
متن کاملRelational Data Exploration by Relational Concept Analysis
Relational Concept Analysis [4] is an extension to FCA considering several contexts with relations between them. Often used to extend the knowledge that can be learned with FCA, RCA also meets the issue of combinatorial explosion. The initial specification of RCA implies a monotonic growth of the number of concepts and an exhaustiveness of all the concepts that can be obtained when a fixed poin...
متن کاملConfidence-based Concept Discovery in Multi-Relational Data Mining
Multi-relational data mining has become popular due to the limitations of propositional problem definition in structured domains and the tendency of storing data in relational databases. Several relational knowledge discovery systems have been developed employing various search strategies, heuristics, language pattern limitations and hypothesis evaluation criteria, in order to cope with intract...
متن کاملMulti-Relational Data Mining
An important aspect of data mining algorithms and systems is that they should scale well to large databases. A consequence of this is that most data mining tools are based on machine learning algorithms that work on data in attribute-value format. Experience has proven that such ’single-table’ mining algorithms indeed scale well. The downside of this format is, however, that more complex patter...
متن کاملOn-demand Relational Concept Analysis
Formal Concept Analysis and its associated conceptual structures have been used to support exploratory search through conceptual navigation. Relational Concept Analysis (RCA) is an extension of Formal Concept Analysis to process relational datasets. RCA and its multiple interconnected structures represent good candidates to support exploratory search in relational datasets, as they are enabling...
