Title

Experiences of harvesting Web resources in engineering using automatic classification

Source

Ariadne magazine. 2003, no.37

Year

2003

Abstract

Authors describe the background and the work involved in setting up Engine-e, a Web index that uses automatic classification as a mean for the selection of resources in Engineering. Considerations in offering a robot-generated Web index as a successor to a manually indexed quality-controlled subject gateway are also discussed
