Penn State Event Data
The Penn State Event Data Project (formerly Kansas Event Data System) is a long term project aimed at collecting events among political actors. The events are extracted from regular news reports in a semi-automatic fashion. Specifically, we use data encoding events in or around the Persian Gulf region in the time from 1979 to 1999 available at http://eventdata.psu.edu/data.dir/gulf.html under the link Gulf data coded from full stories. This data set consists of more than 304 thousand events; the first lines in the file look like this.

The file encodes a tab-separated table whose rows have the following components (from left to right).
- A 6-digit number encodes the time when the event happened, given by the day. For instance, the string 790415 refers to April 15, 1979.
- The source actor is the one who initiates the event. This can be a country (e.g., SAU for Saudi Arabia), an organization (e.g., UNO), or - depending on the data set - even an individual person.
- The target actor is the recipient of the event and is coded in the same way as the source.
- The event type is a three-digit number giving the event code as defined in the World Event/Interaction Survey (WEIS) project. It specifies what happened in the event.
- The last column is a textual description of the WEIS event type.
