Anonymous Microsoft Web Data Data Set (R language)
We created the data by sampling and processing the www.microsoft.com logs. The data records the use of www.microsoft.com by 38000 anonymous, randomly-selected users. For each user, the data lists all the areas of the web site (Vroots) that user visited in a one week timeframe.
Users are identified only by a sequential number, for example, User #14988, User #14989, etc. The file contains no personally identifiable information. The 294 Vroots are identified by their title (e.g. "NetShow for PowerPoint") and URL (e.g. "/stream"). The data comes from one week in February, 1998.

We created the data by sampling and processing the www.microsoft.com logs.
The data records the use of www.microsoft.com by 38000 anonymous,
randomly-selected users. For each user, the data lists all the areas of
the web site (Vroots) that user visited in a one week timeframe.
Users are identified only by a sequential number, for example, User #14988,
User #14989, etc. The file contains no personally identifiable information.
The 294 Vroots are identified by their title (e.g. "NetShow for PowerPoint")
and URL (e.g. "/stream"). The data comes from one week in February, 1998.
Dataset format:
-- The data is in an ASCII-based sparse-data format called "DST".
Each line of the data file starts with a letter which tells the line's type.
The three line types of interest are:
-- Attribute lines:
For example, 'A,1277,1,"NetShow for PowerPoint","/stream"'
Where:
'A' marks this as an attribute line,
'1277' is the attribute ID number for an area of the website
(called a Vroot),
'1' may be ignored,
'"NetShow for PowerPoint"' is the title of the Vroot,
'"/stream"' is the URL relative to "http://www.microsoft.com"
-- Case and Vote Lines:
For each user, there is a case line followed by zero or more vote lines.
For example:
C,"10164",10164
V,1123,1
V,1009,1
V,1052,1
Where:
'C' marks this as a case line,
'10164' is the case ID number of a user,
'V' marks the vote lines for this case,
'1123', 1009', 1052' are the attributes ID's of Vroots that a
user visited.
'1' may be ignored.- Attribute (A): the description of the website area
- Case (C): the case for each user, containing its ID
- Vote (V): the vote lines for the case
The ratings matrix is preprocessed by independent R program
