Description

• This data was first collected in November, 2003 at the Computer Science Department at UIUC.
• To collect the data the dblp bibliography server was occassionally crawled to gather information about an author. The crawl would result in a set of html pages which where then transformed into XML pages.
• This data was collected as a designed experiment for the purpose of Entity Integration.
• There has been some preprocessing of the data that has been done. The preprocessing steps are as follows
  • The data that was collected had unicode characters that most standard XML parsers could not handle. These characters were replaced by the nearest alphabet available.
  • The ID attribute in the schema was not present in the original data set. This is generated by concatenating the researchers name (in a modified form) and the publication number for that researcher. This ID is unique for every publication.
• As of now the Projects that have used this data are:
  • The PROMER project.

Data Format

The data is stored in XML format. The XML DTD is also provided to help the users understand the data. There are four access formats to the data that are provided.

• The user can browse through the publication information of one researcher at a time through the "Browse Data Set by Researcher" link.
• The user can download the entire data set in a Single XML file which is provided also in a gzipped format
• A tar ball of XML files containing information about one Researcher.
• A tar ball of actual HTML pages collected from the dblp website
