HEADLINE: Scientists try to map world's information
DATELINE: ARLINGTON, Va., April 7 (UPI)
BODY:
About 20 U.S. computer scientists are attempting to create maps of science from the ever-growing and
constantly evolving ocean of digital data.
College students might use such maps to see how well a syllabus covers a field's major topics, while
companies could map out plans for targeting their investments, said the scientists, who are working under
grants from the National Science Foundation.
Several efforts are trying to analyze article collections and map out landscapes that humans can view.
Some methods "read" scientific articles and use understanding the content as the basis for a map. Other
methods use relationship networks between the articles, such as citation of other papers.
Such scientific landscapes might have hundreds of possible dimensions, their designers said, presenting a
challenge in creating two- or three dimensional maps.
