I Integration of Data Sources through Data Mining
نویسنده
چکیده
• Source databases can be organized by using several different models, such as the relational model, the object-oriented model, or semistructured models (e.g., XML). • Information stored in a single table in one relational database can be stored in two or more tables in another. This problem is common when source databases show different levels of normalization and also occurs in nonrelational sources. • A single field in one database, such as Name, could correspond to multiple fields, such as First Name and Last Name, in another.

Integration of Data Sources through Data Mining
INTRODUCTION Integration of data sources refers to the task of developing a common schema as well as data transformation solutions for a number of data sources with related content. The large number and size of modern data sources make manual approaches at integration increasingly impractical. Data mining can help to partially or fully automate the data integration process.

متن کاملJoint Bayesian Stochastic Inversion of Well Logs and Seismic Data for Volumetric Uncertainty Analysis
Here in, an application of a new seismic inversion algorithm in one of Iran’s oilfields is described. Stochastic (geostatistical) seismic inversion, as a complementary method to deterministic inversion, is perceived as contribution combination of geostatistics and seismic inversion algorithm. This method integrates information from different data sources with different scales, as prior informat...
متن کاملRatio Rule Mining from Multiple Data Sources
Both multiple source data mining and streaming data mining problems have attracted much attention in the past decade. In contrast to traditional association-rule mining, to capture the quantitative association knowledge, a new paradigm called Ratio Rule (RR) was proposed recently. We extend this framework to mining ratio rules from multiple source data streams which is a novel and challenging p...
متن کاملUnstructured information integration through data-driven similarity discovery
Information integration from multiple heterogeneous sources is one of the major challenges facing enterprises and service providers today, and one of the important problems in this domain is the integration of structured and unstructured (or text) data. In this paper we describe our work on a data-driven approach to integrating various sources of text data, without relying on the availability o...
