New Specialty Database: Science: ChemxSeer to Hunt Molecules Online; Also Say Hello to TableSeer
The exciting and pioneering work of Dr. C. Lee Giles and his students/colleagues (more about Dr. Giles here) at Penn State University continues. We have background about his past work following today's news.
Today's news is on the release of ChemxSeer. Giles is the codirector of the project.
ChemxSeer, the first publicly available search engine designed specifically for chemical formulae, can sort out when "He" refers to helium and not a person more than nine times out of 10, according to the Penn State College of Information Sciences and Technology (IST) researchers who created the tool.
With the new engine, scientists searching for research on CH4 or methane no longer have to wade through search results about Channel 4 or Chapter 4 as ChemxSeer will only return documents with references to the chemical formula. "Results from our search engine are much more relevant than results returned by popular search engines," Giles said. "It is one of several cyber tools under development in our lab which will enable better access to and sharing of information and data among scientists and scholars."
So, targeted web searching with a focus on chemistry.
One of many interesting features that make-up ChemxSeer is TableSeer.
From the web site:
This tool automatically identifies tables in digital documents and extracts the contents in the cells of the tables. The contents are stored in a queryable table in a database. TableSeer extracts table metadata, and uses a novel ranking function to search for tables relevant to user queries.
As many of you know, Dr. Giles is one of the developers of ResearchIndex/CiteSeer), a targeted search engine for "scholarly" information (on the open web) and citation information in the areas of computer science, info tech, etc. It predates Google Scholar by several years and continues to offer several features not available elsewhere. Links to CiteSeer can also be seen via Microsoft's Live Search Academic where some articles list and link to "Citeseer citations." Here's an example as seen in the first result.
Dr. Giles is also involved with SmealSearch (scholarly business material) and eBizSearch (no longer online, redirects to SmealSearch). It's hard to tell if SmealSearch is still being updated but it's still worth a look when searching for older material.
See Also: In 2004, the technologies that power CiteSeeer (autonomous citation indexing, for example) was licensed by the Institute for Scientific Information (Web of Science) .
See Also: As we mentioned a couple of weeks ago in this post about science search on the web, Dr. Steve Lawrence (now at Google) and Dr. Gary Flake (now at Microsoft), and Kurt Bollacker worked at NEC Research with Giles.

Recently I have found myself cooing over visualisation maps (and heat maps) of health and well being resources. The content rich data is overlayed with mapping technologies, and some interesting themes and patterns are emerging.
A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?
Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.
What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
