  1. Efficient Mining of Recurrent Rules from a Sequence Database David Lo Siau-Cheng Khoo Chao Liu DASFAA 2008

  2. Outline • Introduction • Preliminaries • Generation of Recurrent Rules • Algorithm • Performance Evaluation • Conclusion

  3. Introduction • Mining for knowledge from data has been shown useful for many purposes ranging from finance, advertising, bio-informatics and recently software engineering. “Whenever a series of precedent events occurs, eventually another series of consequent events occurs”

  4. Introduction 1. Resource Locking Protocol: Whenever a lock is acquired, eventually it is released. 2. Internet Banking: Whenever a connection to a bank server is made and an authentication is completed and money transfer command is issued, eventually money is transferred and a receipt is displayed. 3. Network Protocol: Whenever an HDLC connection is made and an acknowledgement is received, eventually a disconnection message is sent and an acknowledgement is received.

  5. Preliminaries • Linear-time Temporal Logic (LTL) ‘G’ specifies that globally at every point in time a certain property holds. ‘F’ specifies that a property holds either at that point in time or finally (eventually) it holds. ‘X’ specifies that a property holds at the next event.

  6. Preliminaries

  7. Preliminaries • Checking/Verifying LTL Expressions. (main, lock) → (unlock, end) (main, lock, use) → (unlock, end)
