Information visualization is an effective means of communicating information on large quantities of data. It allows the user to quickly identify patterns and relationships that might otherwise remain buried in long stretches of sequential alphanumeric data. The financial services industry uses this method to make sense of reams of data on companies and markets. Information scientists also use this method to make sense of citation patterns among scholars. Take a look at this document posted on Drexel University's web site. It shows multiple visuals of "co-citation networks".

Now a company named Groxis has brought its information visualization software, Grokker, to the free web through an agreement reached with Yahoo. There's also a more advanced version for a fee. Grokker provides "A New Way to Look at Search". The principle behind Grokker is that the sequential lists of web sites that search engines provide are ineffective for complicated, multi-faceted searches because relevant web sites are often buried on the 9th, 23rd, or 64th page of results and few have the time or patience to scroll away the day. Instead, Grokker provides a visual "lay of the land", an overview in pictures that helps you to understand the different angles of your topic. Once you get an initial results screen, you can drill down on the areas that you're most interested in. It functions a bit like a table of contents in a book.

So take a look and play around with Grokker. This product will probably be followed by many more like it because information visualization has the potential for making web searching more intelligible and efficient.

An interesting article in this week's Chronicle of Higher Education (51.45 (15 July 2005): A35) (the online version may require a password, inquire from one of us and we can give it to you) about using wikis in the classroom. It focuses on professor Mark Phillipson's use of a class wiki to get his students writing about Romantic poetry. The article briefly discusses the uses and benefits of a wiki for annotation, discussion, writing, and class participation.

If you don't know what a wiki is (and that article doesn't explain it well enough for you) check out this article from the most famous wiki, the Wikipedia. Wikipedia has garnered a lot of media attention (especially from librarians) because it is a publicly editable (anyone can edit it) online encyclopedia. Like any other reference source it has its pluses and minuses, but many fear that the lack of traditional peer-review negates its utility as a reference for information.

The U.S. National Institutes of Health (NIH) plays an important role in fostering biomedical research and providing publicly accessible databases like PubMed, PubMed Central, and the genetic resources of NCBI. It funds research in-house as well as in the academic and private sectors. All in all, it plays a vital role in encouraging basic biomedical research.

Recently, NIH has come into conflict with The American Chemical Society (ACS), the largest professional chemical society in the US and a vendor of important subscription-based information products, over a new NIH database called PubChem. In 2002 NIH created a framework known as the NIH Roadmap in order to optimize biomedical research. PubChem is the chemical informatics component, containing information on small molecules that may be used in areas such as drug discovery and the study of gene function. ACS is concerned that PubMed replicates and therefore unfairly competes with its own CAS Registry, a database that provides curated substance identification of small molecules. They have asked the NIH to avoid any significant duplication of the CAS Registry. ACS has also asked Congressional supporters to put pressure on the NIH, but the House Appropriations Committee has approved NIH's annual budget and asked both parties to work together to settle the dispute.
