how well it works. Randomly appearing tips are a bit irritating. No
other major complaints; seems to work pretty well.

natural language as for Alta Vista. Proximity selector is nice feature.

visually distracting. Did not like not being able t osee number of hits
without going to the very end. Did not understand why sometimes 50 hits
were returned and why sometimes many more.

May like Alta Vista better - but maybe only because it is familiar. 
Maybe I don't understand search engines - but I didn't feel the survey
helped me to form an opinion on the value of either one.

if I was searching for a seminar. I probablywould have searched for
""Writing About History"" in quotes. I said ""no"" to the question ""Are
you closerto the information you"" need ornot?"" (number 6, ""writing
NEAR history"") because the first relevent link (which was from the
April calendar of events) was 15th in the ranking. I received only one
hit for ""writing about history, but it was a good one: the History
Course Register for 1997 --which lists the course, and links to the
Course and Room Roster and the CourseTimetable. Also, the simple query
gave me the same result (I used the simple version first by mistake). I
said ""No"" to ""Are you closerto theinformation you needor not"" in
number6 of Part II, becausethe first page of hits were all documents
from theGartner Group, about directions incomputing -- I got better
results with the natural language query and with just the "U.S.
Robotics" quoted search.

exactly how many were returned -- this may be my ignorance. I didn't
want to follow page by pageto figure it out because AltaVista foundsome
2000 hits for those samesearches. Part II, number 1: I went backto using
""rank"" for proximity, though it wasn't specified. Went back and did
the same searches using ""one word"" justin case; search times were 1/2
to one second longer, and with fewer results (1 versusthe 11 I received
fornumber 3, for example) -- but those results were better. Part II,
Number 4: first two pages were all lists of supported products, and old
essays from PennPrintout-- but the third page gave me alist of Vendor
support lines! Part III, number 2: the detailed context available by
button is very helpful--I especially like that you canfind othe
rdocuments that point to the one theengine found. But I would like to
have the URL listed. Part III, number 3: the results of hitting the

research in a specific department, but I don't see any documents in my

I think that Webinator is better than what we currently have (almost
anything is) but AltaVista is clearly better. I think that you would do
well to customize the AltaVista interface a little bit -- maybe offer a
few search fields (the user fills in as much or as little as he/she
wants) and then the form output passes through Alta Vista's Advanced
query engine?  I canelaborate, if need be (aedelman@english.upenn.edu).

"I am more experienced on AltaVista.  That said, I like the
possibilities of searches with webinator, though the test didn't
exercise them all (set searches? more with the proximity and comparisons
of the various settings). If most Penn folks know AltaVista more, it
might be more intuitive.  On theother hand, Webinator feels more like
Franklin's search engine, with the similar power.

1. In addition to the summaryevaluation, I would have liked to rate each
of the listed criteria for each product. 2. The comparison was
complicated because Webinator kept timing out, and it seemed more
finicky about syntax of search entries - for example "+writing+history"
returned nothing, whereas 
"+writing +history" returned a bunch.

+ There were a lot of ways to search and it was fairly intuitive to use.

"Overall, I'd say that Alta Vista was the best.  It combined the
easy-to-use simple interface with power, accuracy,and incredible speed.
Most importantly, I was able to quickly and easily find what I was
looking for.  Webinator required a bit more tuning to find what I was
searching for.

Strangely enough, even though it appears that Webinator may actually do
a better job of zeroing in on materials, I still like Alta Vista better,
partially out of brand loyalty, but also because I like to have zillions
of things put in front of me so that I can do the work of looking for
materials -- it gives me the sense that *I* am in charge, and that the
big-brother aspects of information retrieval are lessened, even though I
get deluged with extraneous materials.  But I have been using AltaVista
for a long time and am very comfortable guiding my way through the
morass of materials it produces. My major comment would be that whatever
we choose, there should be a significant effort to teach people -- very
easily! -- howto use the variables and operating terms ( ~, +, etc) in
order to get the real power out of these systems.  Of course, a really
great interface makes that happen automatically, but I don't feel that
either of these have completely done that.  Whichever we choose should
be accompanied by a genuinely useful guide to cutting through clutter.
On your specific concerns:  no significant difference in speed, and I
did this in the middle of the day on a monday.  Overall power and
richness:  can those operating terms in Webinator get replicated in Alta
Vista?  If not, then it mightbe the more powerful system. Number of
steps:  did not seem very significant difference to me.  Default
interface:  easier on AltaVista than Webinator.  Search results:  always
come up rosy with an experienced operator; hence, the simplest most
powerful interface wins, in situations where you can not count on most
(ie, the most casual) users to invest the time to learn how to do
focussed searches.

Before participatingin this study, I""played"" with the search engines
at Yale and Columbia.I had much better luck finding what I was looking
for at Columbia than at Yale - perhaps it was more to do with the""
nature of their pages than with the search engines.  In both cases, I
did betterfinding what I wanted by simply picking links startingat their
homepages. I guess a well-organized website is as good as any search
engine.

Additional thought - Webinator does not display the number of hits from
a search upfront: can't tell how many hits you have until you scroll
down the display, and then, if it's > 10, you still don't know how many
are lurking.

For the general user,I thinkAlta Vista will be most functional because
it handles simple searches more efficiently.  A non-technical person is
going to have trouble with the more advanced features of ""Webinator,
though those will help researchers more than Alta Vista.

Overall, I liked Webinator better personally. But I think the fact that
it can't search outside of Penn would make Alta Vista the better choice
for the average Penn user.
