  1. PSYCHO: A Prototype System for Pattern Management Barbara Catania, Anna Maddalena, Maurizio Mazza DISI - University of Genoa, Italy VLDB ’05 – Trondheim (Norway)

  2. What is a pattern? Any compact and rich in semantics representation of raw data

  3. PSYCHO Aim Customizable system for generating, representing, and manipulating heterogeneous patterns, possibly user-defined

  4. Related Work • Theoretical proposals • Inductive databases (CINQ project): data mining patterns, no combination • 3World model: data mining patterns represented as linear constraints, combination supported • Standards: only data mining patterns, no combination, no synchronization • representation: PMML, CWM-DM • manipulation: Java Data Mining, SQL/MM DM

  5. PSYCHO added value • Powerful pattern model • user-defined patterns • pattern hierarchies • relationship with source data • Pattern Manipulation Language (PML) • extraction/direct insertion • validity, synchronization • Pattern Query Language (PQL) • selection • combination of patterns of possible different types • combination of patterns and data (cross-over queries)

  6. pattern type class 1..1 0..* name name 1..1 0..* structure schema source schema pattern 0..* measure schema 1..1 PID validity period schema structure 0..* image formula source mining function measure function 1..1 measure 0..* 0..* validity period name name code code image expression PSYCHO pattern model PANDA EU project (IST-2001-33058)

  7. User interface Import/Export Java PBMS Engine Query processor Jasper + SICStus Prolog Formula handler PML interpreter Oracle 10g + Oracle Data Mining PDL interpreter Pattern Base Data sources PBMS ... PSYCHO architecture

  8. Scenarios • Scenario 1 • manipulation and querying capabilities over (heterogenous) data mining patterns • Scenario 2 • representation and management of pattern hierarchies • Scenario 3 • representation and management of user-defined patterns
