A data stream is a sequence of time-stamped data elements which arrive on-line, at consecutive time points. In this work we propose a multi-relational approach to mine complex data streams in order to identify novelty patterns which target new or unknown situations in the stream. Multi-relational data mining is motivated by the existence of several real-world data stream applications where data...

Offshore outsourcing has facilitated exchange of knowledge and services with clients and suppliers situated in diverse economic markets. To better manage knowledge exchange and mitigate risks from international partnerships, client and suppliers use various elements of relational governance practice. This study investigates three cases engaged in supplier-client relationships, to examine how th...

Document Type Definition (DTD) is very important because it contains a set of rules that specifies and captures the structure of XML (eXtensible Markup Language) document. Most of the current approaches for generating DTD from relational views do not support nested elements for DTD. Furthermore, these approaches may not generate automatically DTD from flat relational views where they depend on ...

Three experiments investigated whether the similarity of relational structures influences the interpretation of spatial representations. Adults were shown diagrams of hand gestures paired with simple statements and asked to judge the meaning of new gestures. In Experiment 1 the gestures were paired with active declarative statements. In Experiment 2, the gestures were paired with conjunctive an...

The Ottawa Charter for Health Promotion exhibits a substantialist approach to the agency-structure dichotomy. From a substantialist point of view, both individual agency and social structure come preformed and subsequently relate to and influence one another, starkly positioning the choices made by individuals against the structured sets of opportunities and constraints in reference to which ch...

BACKGROUND The need for better partnerships between Aboriginal organisations and mainstream agencies demands attention on process and relational elements of these partnerships, and improving partnership functioning through transformative or iterative evaluation procedures. This paper presents the findings of a literature review which examines the usefulness of existing partnership tools to the ...

With the growing interest on Network Analysis, Relational Data Mining is becoming an emphasized domain of Data Mining. This paper addresses the problem of extracting representative elements from a relational dataset. After defining the notion of degree of representativeness, computed using the Borda aggregation procedure, we present the extraction of exemplars which are the representative eleme...

Due to their numerous benefits, relational systems play a major role in storing XML documents. XML also benefits relational systems by providing a means to publish legacy relational data. Consequently, a large volume of XML data is stored in and produced from relations. However, relational systems are not well-tuned to produce XML data efficiently. This is mainly due to the flat nature of relat...

Extended Abstract In this Note I prove a representation theorem for Peirce algebras introduced in Brink, Britz and Schmidt (1994b, 1994a). I show that the class of full Peirce algebras is characterised by the class of complete and atomic Peirce algebras in which the set of relational atoms is restricted by two conditions. One requires simplicity. The other requires that each relational element ...
