APPLICATIONS OF INDUCTION TECHNIQUE USING ATTRIBUTE-ORIENTED FOR THE BOOK CIRCULATION DATA AT LIBRARIES (CASE STUDY: DATA CIRCULATION OF IPB CENTER LIBRARY). The book circulation data at libraries, especially at IPB Center Library,are being recorded everyday creating a collection of big-sized data. The data include book loans andreturns for every student from all the faculty, including the Faculty of Post-Graduate School. To see thedifferent characteristics of book loaners from every faculty, the book loans data collection can beanalyzed using the Attribute-Oriented Induction approach. The information gained hopefully could beuseful for the library manager to improve the services offered to the visitors. Attribute-Oriented Inductionis a method used to extract generalized data from the actual data in a database. The result of theexperiment showed that the most relevant attribute to describe book loaners class between faculties is theBook Class on the most general classification in UDC format, with the value of Information Gain of 0.066224. Based on the cross-tabulation and the rules derived, it is concluded that the Book Class whichhas the highest possibility of being loaned by all IPB students is the book class 500 (Mathematics andNatural Sciences). The book classes that have the lowest possibilities of being loaned by IPB students arethe book class 000 (Generalities), 100 (Philosophy), 200 (Religion), 400 (Phylogogy of LinguisticLanguanges), 700 (The Arts. Recreation. Entertainment. Sport, Etc), 800 (Literature), and 900 (Geography. Biography. History). Keywords: Attribute-Oriented approachImas S.
