Data Set Information:
The data comes from Internet Information Server (IIS) logs for msnbc.com and news-related portions of msn.com for the entire day of September, 28, 1999 (Pacific Standard Time). Each sequence in the dataset corresponds to page views of a user during that twenty-four hour period. Each event in the sequence corresponds to a user's request for a page. Requests are not recorded at the finest level of detail---that is, at the level of URL, but rather, they are recorded at the level of page category (as determined by a site administrator). The categories are "frontpage", "news", "tech", "local", "opinion", "on-air", "misc", "weather", "health", "living", "business", "sports", "summary", "bbs" (bulletin board service), "travel", "msn-news", and "msn-sports". Any page requests served via a caching mechanism were not recorded in the server logs and, hence, not present in the data.
Other Relevant Information:
* Number of users: 989818
* Average number of vitis per user: 5.7
* Number of URLs per category: 10 to 5000
Attribute Information:
Each category is associated--in order--with an integer starting with "1". For example, "frontpage" is associated with 1, "news" with 2, and "tech" with 3. Each row below "% Sequences:" describes the hits--in order--of a single user. For example, the first user hits "frontpage" twice, and the second user hits "news" once.
