Relational attribute systems
We introduce a relational operationalisation of data which generalises, among others, the deterministic information systems of [22], the indeterministic systems of [15] and [20], and the context relation of [26]; it can also be used for fuzzy data modelling. Using an example from the area of psychometrics, we show how our operationalisation can lead to an improved understanding of agreements an...
متن کاملRelational Attribute Systems II: Reasoning with Relations in Information Structures
We describe deduction mechanisms for various types of data bases with incomplete information, in particular, relational attribute systems, which we have introduced earlier in [7].
متن کاملAttribute Retrieval from Relational Web Tables
In this paper, we propose an attribute retrieval approach which extracts and ranks attributes from HTML tables. Given an instance (e.g. Tower of Pisa), we want to retrieve from the Web its attributes (e.g. height, architect). Our approach uses HTML tables which are probably the largest source for attribute retrieval. Three recall oriented filters are applied over tables to check the following t...
متن کاملRelational Knowledge Extraction from Attribute-Value Learners
Bottom Clause Propositionalization (BCP) is a recent propositionalization method which allows fast relational learning. Propositional learners can use BCP to obtain accuracy results comparable with Inductive Logic Programming (ILP) learners. However, differently from ILP learners, what has been learned cannot normally be represented in first-order logic. In this paper, we propose an approach an...
متن کاملAttribute-Oriented Induction in Relational Databases
It is beneficial as well as challenging to learn knowledge rules from relational databases because of the vast amount of knowledge implied in databases and the large amount of data stored in databases. In this thesis, we develop an attributeoriented induction method to extract characteristic rules and classification rules from relational databases. The method adopts the artificial intelligence ...
