AMBIENT (AMBIgous ENTries) is a dataset designed for evaluating subtopic information retrieval.

It consists of 44 topics, each with a set of subtopics and a list of 100 ranked documents.

The topics were selected from the list of ambiguous Wikipedia entries; i.e., those with "disambiguation" in the title 
(see wikipedia disambiguation page

The 100 documents associated with each topic were collected from a Web search engine as of January 2008,
and they were subsequently annotated with subtopic relevance judgments.

The AMBIENT dataset consists of four files where each row is terminated by Linefeed (ASCII 10)
and fields are separated by Tab (ASCII 9). The four files are described below.

==================== topics.txt ========================

It contains topic ID and description

ID	description
1	Aida
2	B-52
3	Beagle

==================== subTopics.txt ========================

It contains subtopic ID (formed by topic ID and subtopic number) and description; 

ID	description
1.1	Aida, female given name
1.2	Aida can be a Japanese name
1.3	A Persian name


==================== results.txt ========================
The file is obtained directly by the search engine API and characters are coded using UTF8 (a variable-length character encoding for Unicode).
e.g. é  195 169 codifies the small letter e with acute accent.
It contains result ID (formed by topic ID and search engine rank of result), url,  title, and snippet
