Association and Sequencing Products


DBMS, Data Mining Solutions Supplement

A number of data mining products support association and sequencing. All these are suite products that include other data mining algorithms such as classification and regression.

HyperParallel Inc. //Discovery (UNIX on Sun, Pyramid, and NCRıs Worldmark) with the //Affinity engine supports both association and sequencing. It has limited presentation capabilities but numerous options and controls over the algorithm. It allows users to select from time-related objectives, making it especially strong in sequencing. //Discovery supports item hierarchy as well as product grouping and multistore analysis. It uses parallelized algorithms for scalability.

IBM Corp. Intelligent Miner (AIX, OS400, MVS) supports both association and sequencing. The product's sequencing algorithm is more limited than most, as it supports only subsequent transactions. It supports item hierarchies. Rules can be presented either as tables, or in natural language. Intelligent Miner's algorithm is scalable on parallel processing architectures.

Integral Solutions Ltd. Clementine (UNIX, VMS, and Windows NT) supports association only. It requires that data be in horizontal format. As a result, its algorithm is less flexible than most. It does not compute lift, which is a significant drawback.

NCR Corp. Knowledge Discovery Workbench is an NCR implementation of Integral Solutions Ltd.'s Clementine.

NeoVista Software Inc. Decision Series (UNIX on DEC, HP, and Sun) with DecisionAR supports both association and sequencing, with extensive controls for both algorithms. For sequencing, it supports distinction between subsequent visit and next visit. Decision Series's algorithm is scalable on parallel processing architectures.

Silicon Graphics Inc. MineSet (Silicon Graphics Indy/OS2/Indigo workstations and Challenge and Origin servers) supports association only. The algorithm is more limited than most; it will only find rules with a single item in the left-hand side, only find rules with positive lift, and has no item hierarchy. MineSet has the best visualization of all products, however.


Estelle Brand (estelle@xore.com) and Rob Gerritsen (rob@xore.com) are founders of Exclusive Ore Inc., based in Bluebell, Pennsylvania, which is a consulting and training company specializing in data mining. During the last two years they have used more than a dozen data mining products. Their database management systems experience dates back to the dark ages.
