Web Science 2014 Data Challenge
The datasets described below are used in the Web Science 2014 Data Challenge. For more, information, please the call for participation. For updates, see the Data Challenge section of the Web Science 2014 website.
There are 4 datasets in this collection. Each is available as a .tar.gz file containing either .json or .csv files. When the JSON format is used, each .json file contains a single JSON object. The format of that object is dependent on the dataset. See below for details. The datasets have been prepared by Dimitar Nikolov.
1. Web Traffic
A collection of Web (HTTP) requests for the month of November 2009. This is a small sample of the larger click dataset, documented here. (More on Web Traffic project).
JSON object format:
{ 'timestamp': 123456789, # Unix timestamp 'from': '...', # the referrer host 'to': '...', # the target host 'count': 1234 # the number of request between the referrer and target hosts that occurred within the given hour }
The data has been aggregated for every hour of the day. Thus, if more than one request occurred from the same referrer host to the same target host between, say, 2pm and 3pm, this is reflected in the ‘count’ field of the JSON object with a timestamp for 2pm, rather than by a different JSON object with a different timestamp.
Dataset statistics:
- Dataset size: 235M requests
- File size: 2.7GB uncompressed
- Time period: Nov 1, 2009 – Nov 22, 2009
Data: web-clicks-nov-2009.tgz
