I blogged about CiteSeer in the past (see CiteSeer, techXtra and computer science literature), a targeted search engine for computer science, info tech, etc. Now, Dr. Giles (one of the developers of CiteSeer) and his students and colleagues at Penn State have developed another targeted search engine for chemistry.
So what is it?
From the news release:
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.”
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.

PubMed is now available as a search engine add-on on the search bar in the upper-right corner of Firefox 2.0 and Internet Explorer 7.0. From a PubMed Web page (say, PubMed Home Page), click the search box drop down arrow next to the default search engine Google, and then select Add PubMed search.

Gary Price pointed out on his Resource Shelf that Yahoo and Microsoft have recently released similar services. Also Rollyo is online for almost a year and Swicki from Eurekster all offer these types of tools.

search smiley faces in Ask.com (former askjeeves.com) Monday, 28 August 2006 5:08 pmPosted by Dongmei in search engines.
I’m sure that you’re familiar with :), or :(. What about other emoticons? Now you can search these in Ask.com. If you search 😛, it gives the explanation that “:-P is an emoticon that typically means sticking out tongue”.
You can also search chat shorthand such as BRB (Be Right Back).
Pretty cool, isn’t it?
