  1. Automatic discovery of program unitsAutomatyczne przeszukiwanie repozytoriów jednostek programowych Promoter: Jerzy Nawrocki, Professor Bartosz Paliświat

  2. Where can I find program XXX? Goal – reusability improvement • Reusability: • Decreases effort • Improves quality • Improves modularity

  3. Goal – reusability improvement Discovery improvement Reusability improvement

  4. Subject of discovery • Simple methods • Modules • Classes (standalone class or package) • Components

  5. Repository programXXX programYYY Discovery - overview Query engine

  6. WSFL, XLANG Context SemanticWeb Semantic networks UDDI, JNDI Taxonomies Naming conventions, standardization Java Beans, ebXML Interface definition WSDL, IDL Discovery - technologies

  8. Problem What kind of categories should I have in my Taxonomy? Why there is no such category, it’s so obvious!

  9. Problem - example Dictionary

  10. Problem - example Dictionary WITH SPECIALIZED TERMS

  11. Additional filtering Taxonomies, Semantic networks Usage scenarios, canonical aproach Componentfound

  12. Usage scenarios, canonical aproach Additional filtering

  13. Canonical aproach Function(x1:T1, x2:T2, ... x3:T3): RT [0, 0, ..., 0] = 1 [0, 0, ..., 1] = 2 ... [0, 1, ..., 0] = 0 ...

  14. Canonical aproach • Advantages: • Simple and effective way for finding computational functions • Does not require components execution

  15. Canonical aproach • Disadvantages: • Canonical input data may not be accurate • Difficulties with canonical representation of non-basic data types • Exponential number of possible permutations • Applies only to stateless methods

  16. TestCase 1 ? TestCase 2 Usage scenarios

  17. Usage scenarios • Advantages: • Test data provided by user, thus more accurate • State and context aware

  18. Usage scenarios • Disadvantages: • Requires component execution • Difficulties with methods and parameters maping • Complicated component-side description • Exponential algorithms

  19. Thank you ?
