CiteSeer, techXtra and computer science literature Saturday, 27 May 2006 4:03 pm

Posted by Dongmei in computer science, search engines.

For those doing computer science (and applied mathematics) research, I'm sure that you use CiteSeer a lot. (CiteSeer is a public digital library and search engine in computer and information science (and related areas) that's hosted at Penn State, currently includes over 700,000 documents).

TechXtra (used to be called EEVLXtra), an initiative of Heriot Watt University cross-search 25 databases in engineering, math, and computing.

In addition to CiteSeer, TechXtra also searches arXiv ePrints, ePrints UK, NASA Technical Reports, CISTI (Canada Institute for Scientific and Technical Information), EEVL Ejournal Search Engine, Euclid Mathematics and Statistics Journals, and others.

So, when CiteSeer is busy (happens a lot), you can use techXtra as an alternative, however, I do find some discrepancy (tried "vector space model" as an example). And you can't do citation search in techXtra which is a nice feature of CiteSeer


Doing research for math and computer science: in the library and on the Internet (a presentation) Tuesday, 23 May 2006 4:23 pm

Amy in the Math Dept. asked me if I could do a presentation for her research group which includes two graduate students, three undergraduate students ( I knew Amy from the New Faculty Orientation, we both came to CofC last summer). I asked what kind of research they will be doing, it seems that they'll study a lot in between math and computer science, general topics are text mining, information retrieval, esp. Web information retrieval (to be more specific, Fiedler vector, Spectral graph partitioning, PageRank — mathematics of, vector space model, latent semantic indexing). We chatted and after much preparation, this is the presentation that I came up with. I also put together a resource page for the group.

Here is the presentation (http://www.cofc.edu/~caod/present4amy.ppt), you should be able to download to your PC or open it in a browser. Here is the resource page (http://www.cofc.edu/~caod/resources_guide4amy.html).

I learned (or reinforced) quite a few things during the preparation for this presentation, I hope you too :-).
