  3. 3. Introducing Data Mining Data mining is one process of extracting patterns from data. Data mining involves sorting through large amounts of data and picking out relevant information. Data mining can be used in any organization including library to apply to the two separate processes of knowledge discovery and prediction. Data mining is one of the important parts of Bibliomining, where large amount of data are associated with the library systems in order to aid decision-making or justify services. Data mining and its elements, functions, process and some other involving factors have been discussed in this paper. SIS-2012 3
  4. 4. Scope of Data Mining Automated prediction of trends and behaviors: Data mining automates the process of finding predictive information in large databases. Questions that traditionally required extensive hands-on analysis can now be answered directly from the data — quickly. Automated discovery of previously unknown patterns: Data mining tools sweep through databases and identify previously hidden patterns in one step. An example of pattern discovery is the analysis of retail sales data to identify seemingly unrelated products that are often purchased together. SIS-2012 4

  7. 7. Elements of Data Mining Extract, transform, and load transaction data onto the data warehouse system Store and manage the data in a multidimensional database system Provide data access to business analysts and information technology professionals. Analyze the data by application software. Present the data in a useful format, such as a graph or table.

  9. 9. BibliominingA new term to describe the data mining process inlibraries is Bibliomining (Nicholson and Stanton, Inpress). Bibliomining is defined as “the combination ofdata mining, bibliometrics, statistics, and reporting toolsused to extract patterns of behavior-based artifacts fromlibrary systems” (Nicholson, 2002). Instead of behavior-based artifacts, however, this project is usingbibliomining to discover patterns in artifacts contained inand associated with Web pages. The techniques todiscover novel and actionable patterns still apply. SIS-2012 9
  10. 10. Conclusion The need and application of data mining has become essential to manage, organize, and disseminate information to the right users at right time. Though it is primarily intended for the business class, still then it has got practical implications in Libraries and Information Centers due to overwhelming growth of literature especially in digital formats. Now-a-days, more and more digital data are being collected, processed, managed and archived in Libraries and Information Centers to suit to the varied need of the user communities every day.
