Abstract—Closed frequent itemset mining plays an essential role in data stream mining. It could be used in business decisions, basket analysis, etc. Most methods for mining closed frequent itemsets store the streamlined information in compact data structure when data is generated.

Whenever a query is submitted, it outputs all closed frequent itemsets. However, the online processing of existing approaches is so slow that those methods cannot deal with data streams generated at a high speed. In this paper, a novel method DELAY-CFIM for mining closed frequent itemsets is proposed to solve the problem of slow online processing. It divides the closed frequent itemset mining process over data streams into two steps. Firstly, when transactions are generated, it stores the frequency information of itemsets in a summary data structure. Then it mines closed frequent itemsets until a query is submitted. The method can improve the speed of online processing.

Abstract. In this work we present an approach, based on a

Knowledge Federation, for the management of the information regarding the life-cycle of Software Application ad IT services for organizations' operations. We need many information about software and IT to study the software product's life-cycle management, and to understand the lifecycle of information, which is based on four phases: introduction, growth, maturity, and decline. We need a knowledge base about the products and their costs to understand how to manage the single software products. We will focus our attention on mapping software applications,

Abstract— Maintainability denotes the ease of a defect correction or software changes that is extremely dependent on how simple the software can be understood and tested. The flexibility of a system is strongly linked to the maintainability of a system. High maintainability is essential for systems that are to go through periodical revisions and for products that are developed quickly. Most of the researchers do not have the adequate knowledge to define how maintainability quality factor should be assessed. This paper aims to claim the entities to be used in placing maintainability requirements and describe them into metrics. Then the main contribution of the proposed manuscript is the interpretation of the vague external maintainability quality attribute or in other words the imprecise non-functional requirements into specific structured functional requirements for implementation in the software system project.
