Author as an IconAuthor as an IconAn author– represents a person;– represents a body of writings.
A group of related authors – comes to stand for a body of ideas– represents subject relationships of
documents.

Data for Information Scientists MapData for Information Scientists Map
120 highly cited authors in Information Science
Co-citation count of every pair of the 120 authors
A matrix of 120 by 120 of their co-citation counts, converted to Pearson r’s

Data CollectionData CollectionLabor-intensive process– Decided who are highest-cited authors
in the field– Conducted thousands of DIALOG
searches on paired authors• C(120, 2) =7140 searches
– Processed data in a spreadsheet White and McCain (JASIS, April 1998)

New Interactive SystemNew Interactive SystemThe challenges– To process data and generate the map
instantly. – To provide interactive functions for the
viewer to explore the map and the underlying data (with search engines).
– To provide different maps (with different mapping algorithms).
