Word clouds open windows to content inside research documents

information bridge

To give you a window into the content of full-text research documents, OSTI has added word clouds in Information Bridge. Information Bridge provides free public access to over 200,000 full-text documents and bibliographic citations of Department of Energy research report literature. The word clouds visually represent word frequency within each document and can be viewed from the search results screen or on the bibliographic citation page when hovering over the title or the PDF icon. The top 50 terms are shown alphabetically within the word cloud. Font size is determined by the frequency of usage within the document.  Depending upon the term weighting, fonts can be as much as 80 percent larger than the least used terms in the document. The colors are random. Documents in Information Bridge are primarily from 1991 forward and were produced by DOE, the DOE contractor community, and/or DOE grantees. Legacy documents are added as they become available in electronic format.
