_ADS Abstract Service: A Remarkable Eclectic Index_
In response to my recent posting for candidates for my new column in Library
Hi Tech News tentively titled e-Profiles, Michael Kurtz, an astronomer
and computer scientist with the Smithsonian Astrophysical Observatory
http://cfa-www.harvard.edu/~kurtz/vita.html ] reminded me about the ADS
Abstract Service of the Astrophysics Data System
http://adsabs.harvard.edu/abstract_service.html [See below for
edited reponse which is re-posted with his permission] Upon reading
the 'What's New'
http://adsabs.harvard.edu/abs_doc/whatsnew.html ] section (as well as
Michael instructions below) I've concluded that this is perhaps the
finest example of an Eclectic Index/Abstracting service that I know.
I defined Eclectic in the context of e-journals in a recent posting:
"By the "Eclectic Journal", I mean a Web-based resource that at its core
provides access to e-journals that offer not only access to the conventional
content of a digital form of a journal but
also provides or permits interaction with novel and innovative _features
and functionalities_ (e.g., reference linking, cross-publisher searching,
page customization, open peer review, etc.) _AND_ novel and innovative
_content_ (e.g., e-Books, pre-publication history, electronic
discussions, translation services, e-prints, bibliographic
databases, etc.)"
http://sunsite.berkeley.edu/Web4Lib/archive/0101/0131.html
Here's are some the features, functionalities, and content I find noted for
in the ADS Abstract Service from its 'What's Next' page:
* Citation indexing
* Collaborative Filtering
* Font, Format, and Display Control
* Database Linking
* Sorting
* Data Extraction
* Access to Dissertations and Theses
* Personalization
* FAX Delivery
* Access to Conference proceedings
[For examples of some of these features in e-journals, see my EJI(sm)
registry http://www.public.iastate.edu/~CYBERSTACKS/EJI.htm I invite
MyWebColeagues to explore this Most Remarkable Eclectic Index at their
earliest convenience, if only to test its ollaborative Filtering
functions and Citation Indexing feature described below.

****************************
I saw a note on the **** listserv from you requesting web resources
for your column.
Essentially every astronomer uses the NASA ADS Abstract Service
http://adsabs.harvard.edu/abstract_service.html The average use by the
average astronomer is more often than once per day.
For a set of articles describing the system go to:
http://adsabs.harvard.edu/pubs/A+AS/
For your column I suggest you look at our use of second order
information retrieval functions. I believe they are unique in their IR
retrieval power among literature search facilities.
I will give you an example of how to use these functions. First go to our
main query page: http://adsabs.harvard.edu/abstract_service.html. Next type
"redshift survey" (use the quotes) into the Enter Text
Words/Keywords window, then click the Send Query button.
You now should have a list of the most recent 100 papers which contain
the phrase "redshift survey" in the abstract, title, or keywords, ordered
by publication date.
Next page to the bottom of this list and click on the button which
says: Get also-read lists for all articles in the above list.
You now have a list of the 500 articles most read (in the last three
months) by people who read articles from the first list, of recent articles
on redshift surveys. The list is ordered by how frequently these articles
were read, thus the list is, in order, those papers currently most read by
people interested in recent work on redshift surveys.
Now page to the bottom of this list and click on the button: Get reference
lists for all articles in the above list.
You now have a list of papers referenced by the 500 papers most read by
people interested in redshift surveys, ranked by the number of times
they were cited. A large number of these papers are not about redshift
surveys, but they are the most generally useful for people interested in
redshift surveys. A more specific list to usefulness to redshift surveys, as
opposed to usefulness
to people who are interested in redshift surveys, could have been gotten by
clicking the return references button after getting the results from the
first "redshift survey" query.
Now (finally) go again to the bottom this list and click on the button
which says: Get citation lists for all articles in the above list. You
now have a list of those articles which cite the largest number of the
articles in the previous list, sorted by the number of articles from that
list which they reference. This is a list of articles with the most
extensive discussions of topics of interest to people interested in
redshift surveys. The high number of references found, both as a fraction
of the papers in an article (49% of the papers referenced in Cole, et al
were in the previous list, 57% from Cohen, et al), and in absolute terms
(105 papers from the list were referenced in Ellis' review article, out of
237 in his reference list) demonstrates clearly that these second order
query methods work very well.
So finally, in response to a simple text query for "redshift survey" we
have four lists of papers:
1. The most recent papers on redshift surveys (What's New?)
2. The most currently popular papers among people interested in redshift
surveys (What's Hot?)
3. The most currently referenced papers by people interested in redshift
surveys (What's Useful?)
4. The papers with the most citations to papers useful to people interested
in redshift surveys (What's Instructional?) [snip]
