Reusable Architecture for INtelligent Brokering Of Web information access

(Further motivation of the name: the different modules for analysis of web data should synergistically "shed light" on the otherwise "obscure" web content, in a similar way as the different colours of the rainbow join together to form the visible light.)

New content:

June 2008: After some period of unavailability, the Rainbow pages have been ported to the KEG server. The project itself is now considered as a stopped one; however, some of its ideas have been transmitted to the K-Space and MedIEQ projects, as well as to the Ex project, which focuses on web information extraction using extraction ontologies.

May 2006: Due to breakdown of our server and migration to an 'emergency' one, some applications relying e.g. on Java (such as the Sesame repository) don't work any longer. We hope to get them back to life again in early Autumn 2006, as soon as we get a new piece of hardware.

1 January 2006: Two new EU projects started, in which the to-date Rainbow team actively participates.

• The K-Space Network of Excellence focuses on multimedia semantics; the synergistic analysis of images and texts, addressed in Rainbow, is one of relevant topics there.
• The MedIEQ project deals with medical website quality labelling using information extraction, also taking advantage of website navigation and classification techniques. It thus directly follows up with previous research on Rainbow, in a specific application domain.

December 2005 - February 2006, section Bibliography
Two overview publications describing Rainbow were published. One is the the habilitation thesis of V. Svatek, Sv05d, and the other is a short paper with summary project presentation Sv06a.

14-16 September, 2005: the First International Workshop on Representation and Analysis of Web Space (RAWS-05) was organised by the Rainbow team, with support from our CSF grant.

Demo of information extractor trained for bike offer pages, see also documentation. Contact Martin Labsky for details. Also refer to the underlying paper La05b.

February 23, 2005, section Downloads and shows
Updated collection of training data with semantic tags (103 pages from bicycle catalogues, in XHTML). The collection is tagged twofold: once with HTML tags visible (colour) in browser, once with semantic XML tags. Contact Martin Labsky for details. Also refer to an underlying paper La05a.
