RefViz 2 text analysis and data visualization tool works with EndNote, ProCite and Reference Manager bibliographic management software, and is available for Mac OS X and Windows. Users can search for references using Reference Retriever, the search interface that queries multiple data sources simultaneously. Enter the query once, and the retriever identifies and retrieves relevant references from each data source, removes duplicates, and automatically creates the data visualization. The software also provides a way to explore reference collections visually for major themes and topics. Users can evaluate large results sets from online searches, and an at-a-glance summary reveals trends and associations in the references, providing an additional level of analysis that allows researchers to find the most relevant citations for their papers.
