Abstract

The significance of statistics plays a major role in society, business and government. In commercial applications, software tools are effectively applying the statistical techniques in order to improve the performance as well as to minimize the cost by drawing timely decisions. This paper focuses the significances of statistics in three main systems namely decision support system, data mining system and data warehousing system. This paper prominently contributes the roles of statistical techniques in DSS, DM and DW systems.

Abstract

Since research trends can change dynamically,researchers have to keep up with these new trends and undertake new research topics. Therefore, research communities for new research domains are important. Domain-specific search engines (or vertical search engines) alleviate the problem to some extent, by allowing researchers to perform searches in a particular domain and providing customized community researchers. In this paper, we propose a method to discover research communities. The key features of our method are a network model of papers and a word assignment technique for the communities obtained. This research work is focused on evaluating a bibliometrics search engine called Domain Expert, which produces list of community researchers e-mail addresses of cyber domain experts available freely in the Web. This exploits techniques such as bibliometrics and community mining using Brush structure, which is a new data structure model for indexing by community formation.

Abstract

The proposed EasyMiner (version 2) will extract knowledge from the data warehouse. The traditional data mining query language (DMQL) requires (a) the set of task-relevant data to be mined, (b) the kind of knowledge to be mined, (c) the background knowledge to be used in the discovery process, (d) the interestingness measures and thresholds for pattern evaluation and (e) the expected representation for visualizing the discovered patterns. These lengthy processes should be minimized so that the query processing time could be reduced. The ultimate goal is to simplify the data mining process by using a simple DMQL through EasyMiner. Normally, DMQL adopt several methodologies at each stage of knowledge mining. But the new DMQL propose some sort of eliminated or updated or simplified model of these methodologies namely concept hierarchy, association rules, classification, data cube, etc., Here the supervised learning ie., classification techniques are used. The user will realize the simplicity of the data mining process through EasyMiner. The outcome of the proposed EasyMiner is that expected knowledge from given data warehouse by saving more amount of query processing time. Further, the level of mining the knowledge might be indicated. The multi-dimensional database could be controlled to 3Ds only in order to maintain the simplification process of the EasyMiner. At last, the EasyMiner will extract the required and/or expected knowledge from the data warehouse by using simplified query processing models.
