Textual and Content-Based Search in Repositories of Web Application Models – TWEB paper

The paper “Textual and Content-Based Search in Repositories of Web Application Models” I co-authored together with Bojana Bislimovska, Alessandro Bozzon, and Piero Fraternali has now been published on the ACM Transactions on the Web (TWEB).

The article examines two different techniques for indexing and searching model repositories, with a focus on Web development projects encoded in the domain-specific language WebML. Keyword-based and content-based search (also known as query-by-example) are contrasted with respect to the architecture of the system, the processing of models and queries, and the way in which metamodel knowledge can be exploited to improve search. A thorough experimental evaluation is conducted to examine what parameter configurations lead to better accuracy and to offer an insight in what queries are addressed best by each system.

On June 23rd, 2009 I chaired the Pharos Federation Day, in Como. The program was the following:

09:30 – 10:00: Welcome and introduction (Marco Brambilla, WBM)

10:00 – 12:00: Exploitation scenarios and possibilities. Open discussion (Tonina Scuderi, ENG)

12:00 – 12:30: Demonstration of the PHAROS platform – front end demo (Alessandro Bozzon, WBM) [30’]

14:00 – 14:30: Demonstration of the PHAROS platform – content provisioning demo (Kathrine Hammervold/ Eric Cai, FAST) [30’]

14:30 – 15:30: The PHAROS platform (Vincenzo Croce, ENG) [1h30]

16:00 – 17:30: Federation role, exploitation and feedbacks – open discussion (Tonina Scuderi, ENG; Marco Brambilla, WBM) [1h]

Special session on Multimedia indexing for content-based search engines at IEEE CBMI 2009

I have been chair of the special session SS3 Multimedia indexing for content-based search engines at CBMI 2009 (7th International Workshop on Content-Based Multimedia Indexing), held in Chania, Crete (Greece).

All the main scientific contributors of the Pharos project will be represented in the session, together with a set of selected invited speakers from other European projects. The event has been a great opportunity for discussion, joint work and presentation of project outcomes.

The presented papers are:

  1. Petros Daras and Apostolos Axenopoulos. A Compact Multi-View Descripto for 3D Object Retrieval
  2. Alessandro Bozzon, Marco Brambilla and Piero Fraternali. Model-Driven Design of Audiovisual Indexing Processes for Search-Based Applications
  3. Reede Ren and Joemon Jose. Query Generation From Multiple Multimedia Examples
  4. Azeddine Zidouni, Mohamed Quafafou and Herve Glotin. Structured Named Entity Retrieval in Audio Broadcast News
  5. Oliver Schreer, Ingo Feldmann, Isabel Alonso, Pedro Concejero, Abdul Sadka and Rafiq Swash. RUSHES – Retrieval of Multimedia Semantic Units for Enhanced Reusability
  6. Peter Dunker, Christian Dittmar, Andre Begau, Stefanie Nowak and Matthias Gruhne. Semantic High-Level Features for Automated Cross-Modal Slideshow Generation
  7. Georges Quenot, Tien Ping Tan, Viet Bac Le, Stephane Ayache, Laurent Besacier and Philippe Mulhem. Content-Based Search in Multi-Lingual Audiovisual Documents using the International Phonetic Alphabet
  8. Cyril Laurier, Owen Meyers, Joan Serra, Martin Blech and Perfecto Herrera. Music Mood Annotator Design and Integration
  9. Alan Smeaton and Sandra Rothwell. Biometric Responses to Music-Rich Segments in Films: The CDVPlex
