Incremental update on sequential patterns in large databases by implicit merging and efficient counting

Current approaches for sequential pattern mining usually assume that the mining is performed in a static sequence database. However, databases are not static due to update so that the discovered patterns might become invalid and new patterns could be created. In addition to higher complexity, the maintenance of sequential patterns is more challenging than that of association rules owing to sequ...

A theory of contexts in information bases

Although semantic data models provide expressive conceptual modeling mechanisms, they do not support context, i.e. providing controlled partial information on conceptual entities by viewing them from different viewpoints or in different situations. In this paper, we present a model for representing contexts in information bases along with a set of operations for manipulating contexts. These ope...

One of the few areas in management accounting and control research that has attained critical mass concerns the organizational and behavioral e€ects of budgeting. Many studies in this area focus on the use of budgets for managerial performance evaluation, and revolve around the construct Reliance on Accounting Performance Measures (RAPM). Despite the volume of the RAPM literature, concern has b...

To Preference via Entrenchment

We introduce a simple generalization of G ardenfors and Makinson’s epistemic entrenchment called partial entrenchment. We show that preferential inference can be generated as the sceptical counterpart of an inference mechanism de ned directly on partial entrenchment.
