The Sogou-SRR Dataset


The Sogou-SRR (Search Result Relevance) dataset was constructed to support researches on search engine relevance estimation and ranking tasks. The dataset consists of 6,338 queries and corresponding top 10 search results. For each search result, the screenshot, title, snippet, HTML source code, parse tree, url as well as a 4-grade relevance score (1-4) and the result type are provided. The queries are sampled from search logs of The sampled queries with frequency between 100 and 10,000 are usually regarded as torso queries , and usually the most important concerns for ranking algorithm design.

Data Instructions

The files and directories contained in Sogou-SRR are shown below. The dataset is totally about 3.2 GB in size when compressed.

File or Directory Data
SRR.json All the information needed for search results in Sogou-SRR.
Screenshot/ The screenshots of search results.
Tree/xml_raw/ The xml files directly parsed from HTML source codes of search results.
Tree/xml/ The xml files of pruned search result parse trees.
Tree/image/ The images in search result parse trees.
Train.txt/Val.txt/Test.txt The training/validition/testing queries.

The “SRR.json” is organized hierarchically. Keys in “results” denote the positions of search results (from 0 to 9). Smaller key number means higher position in the original ranking list of search engine. The key “tree” denotes the parse tree of each search result. It can be either the XML file in “Tree/xml_raw/” or “Tree/xml/”.
