A Reuse-based Spatial Data Preparation Framework for Data Mining

The constant increase in use of geographic data in different application domains has resulted in large amounts of data stored in spatial databases and in the desire of data mining. Many solutions for spatial data mining have been proposed. Most create data mining languages or extend existing query languages to support data mining operations. This paper presents an interoperable framework for sp...

A Framework for Mining Association Rules in Data Warehouses

The effort of data mining, especially in relation to association rules in real world business applications, is significantly important. Recently, association rules algorithms have been developed to cope with multidimensional data. In this paper we are concerned with mining association rules in data warehouses by focusing on its measurement of summarized data. We propose two algorithms: HAvg and...

A Framework for Efficient Association Rule Mining in XML Data

In this paper, we propose a framework, called XAR-Miner, for mining ARs from XML documents efficiently. In XAR-Miner, raw data in the XML document are first preprocessed to transform to either an Indexed XML Tree (IX-tree) or Multi-relational Databases (Multi-DB), depending on the size of XML document and memory constraint of the system, for efficient data selection and AR mining. Concepts that...

A Framework for Efficient Association Rule Mining in XML Data

The performance of a database is greatly affected by the performance of its indexes. An industrial quality database typically has several indexes associated with it. Therefore, the design of a good quality index is essential to the success of any nontrivial database. Parallel to their significance, indexed data structures are inherently complex applications that require a lot of effort and cons...

Portfolio Performance Evaluation in a Modified Mean-Variance-Skewness Framework with Negative Data

   The present study is an attempt toward evaluating the performance of portfolios using mean-variance-skewness model with negative data. Mean-variance non-linear framework and mean-variance-skewness non- linear framework had been proposed based on Data Envelopment Analysis, which the variance of the assets had been used as an input to the DEA and expected return and skewness were the output. C...
