LISp-Miner

LISp-Miner is an academic pattern mining system developed from mid-1990s.The theoretical foundation of the system is constituted by the GUHA method and the observational calculi.

LISp-Miner is primarily a desktop Windows application, but it can be run also in Linux using wine. I:ZI miner interacts with LISp-Miner through a PMML-based format GUHA AR PMML.

Key features

  • Preprocessing module
  • Mining algorithm based on bit-string operations not apriori-family algorithms
  • Multiple pattern-mining procedures
  • 4ft-Miner - mines for association rules. Key features:
    • Negation and disjunction connectives
    • 18 interest measures, which can be freely combined
    • Rules contain the optional condition part in addition to antecedent and consequent.
    • Mines directly on multivalued attributes, no need to create "items"
    • Dynamic binning operators
    • PMML-based import and export
    • Computing grid support
    • I:ZI Miner provides a web interface to this module
  • Action-Miner, KL-Miner, SD4ft-Miner, SDKL-Miner, CF-Miner
    • These procedures are currently not supported by I:ZI Miner
    • SD4ft-Miner and Action Miner support PMML-based export

4ft-miner features not supported by I:ZI Miner

  • Condition part of association rules
  • Handling Missing values
  • Negation wildcard - the system tries the attribute with and without negation
  • Some binning wildcards
  • Cedent and partial cedent lengths. This feature allows to set how many attributes from the task setting must appear in discovered rules. The default used by I:ZI Miner

Screenshots

This section shows LISp-Miner 4ftTask module, where the user defines the mining task, and the 4ftResult module, where the discovered association rules are shown. For comparison, the same task is shown for I:ZI Miner, here the same screen features both the settingĀ  and results.
