In this paper, we provide the preliminaries of basic concepts about association rule mining and survey the list of existing association rule mining techniques. Of course, a single article cannot be a complete review of all the algorithms, yet we hope that the references cited will cover the major theoretical issues, guiding the researcher in interesting research directions that have yet to be e...
In this paper, we provide the basic concepts about association rule mining and compared existing algorithms for association rule mining techniques. Of course, a single article cannot describe all the algorithms in detailed, yet we tried to cover the major theoretical issues, which can help the researcher in their researches. KeywordsAssociation rules, algorithm, itemsets, database.
Based on unique data from a world-wide survey of agents involved in international climate policy, this paper empirically analyzes the importance of equity in this field. We find that equity issues are considered highly important in international climate negotiations and that the polluter-pays rule and the accompanying poor losers rule are the most widely accepted equity principles. Our economet...
Association rule mining is used in various applications. Also information systems may need to take privacy issues into account when releasing data to outside parties. Due to recent advances, releasing data to other parties may be done in a streaming fashion. In this paper, we introduce a new system in which association rule mining over data streams and association rule hiding for traditional da...
The reasoning should tackle big data issues like other domains as the size of ontology grows bigger and bigger. Especially, rule-based reasoning should overcome the following challenges: duplicate elimination and rule matching efficiency. To deal with these challenges, we introduce a new rulebased reasoning method which materializes each generic instance rule into several schema-specific instan...
This final rule updates and makes revisions to the end-stage renal disease (ESRD) prospective payment system (PPS) for calendar year (CY) 2013. This rule also sets forth requirements for the ESRD quality incentive program (QIP), including for payment year (PY) 2015 and beyond. In addition, this rule implements changes to bad debt reimbursement for all Medicare providers, suppliers, and other en...
This paper deals with the principles of rule-based systems in databases and gives an overview of existing approaches. First, we introduce the concept of rules. The application of rule-based systems to databases is categorized. Deductive database systems are introduced as the first extension of classical database management systems. We briefly describe the concept of deductive databases and thei...
The parallel execution of rules in a production system provides the potential for faster execution, but increases the complexity of control and design issues. We address two issues: controlling the execution of productions without introducing serial bottlenecks and maintaining correctness during the course of simultaneous rule executions. Two novel rule-firing policies are described: an asynchr...
In this paper, we present an evaluation of novel rule evaluation support method for post-processing of mined results with rule evaluation models based on objective indices. Post-processing of mined results is one of the key issues in a data mining process. However, it is difficult for human experts to evaluate many thousands of rules from a large dataset with noises completely. To reduce the co...
We present a formal framework that can be used to specify and study a number of different semantics for rule execution in active databases. We shall consider the core of several active rule languages that are already available (e.g., Ariel, Starburst and HiPAC) but whose rule execution is specified only by informal descriptions. The framework is based on a generic active rule language and relie...
