Conference on Data Mining and Data Warehouses (SiKDD 2007)

October 12, 2007, Ljubljana, Slovenia

---------------------------------------- ----------------------------------------

To be held at 10th International Multi-conference on Information Society  IS-2007

Data handling technologies have significantly progressed in the last ten years. The first phases mainly dealing with storing and efficiently accessing the data, resulted in the development of industry delivering tools for handling large databases, standardization of related processes, queering languages, etc. When the data storage was not a primary problem any more the need for improving the database organization resulted in the databases supporting not only transactions but also analytical views of the data. At this point data warehousing with OLAP (On-Line-Analytical-Processing) entered as a usual part of a company information system. The OLAP paradigm still requires from the user to set well defined questions which is not always easy and possible. This led to the development of Data Mining offering automatic data analysis trying to obtain some new information from the existing data and enabling the user some new insights in the data. Further development of methods for Text Mining enables handling textual data in addition to well structured data in databases. Large amount of data and activities on the Web is further  addressed in Web Mining where in addition to content of the Web documents, the structure of  the Web and Web log-files are analyzed.
