This corpus is an extension of the Ambient data set created by Carpineto and Romano. For each subtopic, the websites of the given URLs were downloaded (if accessible). Those documents are named as the original documents, for example, 1/1.4/1.3.html. Each subtopic was then manually enriched to ten documents with websites retrieved by Google (for example, 1/1.1/g00.html - 'g' for Google, 00 for the first Google result). Some subtopics could not be sufficently enriched and were discarded. Moreover, some subtopics were duplicates or not interpretable and were also discarded.
