I am interested in using the Term Extraction webservice (part of the more
general content analysis service). More info here:
http://developer.yahoo.com/search/content/V1/termExtraction.html

However it is not clear to me which Terms Of Use, Terms of Service, and
Guidelines are applicable to Yahoo Term Extraction, aka YTE.

To wit:

1. The Yahoo! Developer Network Guidelines at
http://info.yahoo.com/guidelines/us/yahoo/ydn/ydn-3955.html says "**Some** of
our APIs and Web Services are made available only for non-commercial use. For
such APIs and Web Services, it's NOT PERMITTED to: [...] Access these services
through productivity tools for businesses created to bring value to a business
function, typically only accessible to select users"

-- Q: does YTE apply to this non-commercial use restriction?

2. The Yahoo! APIs Terms of Use (Yahoo Developer Network Terms of Use) at
http://info.yahoo.com/legal/us/yahoo/api/api-2140.html says under Section
1.e.iii,

iii. You represent and warrant to Yahoo! that if you submit or permit the
submission of your or your users' content or activity through or into a Yahoo!
web service or API, you also grant the following perpetual, non-exclusive
license to, use of, and rights to your or your users' content or activity to
others (such "others" may include but are not limited to Yahoo! users): (i) to
access, distribute and/or display your or your users' content or activity; (ii)
the ability for Yahoo! registered users to rate, review, comment on and tag Your
Content; and (iii) the ability to access, reproduce, distribute and/or perform
your or your users' content, activity, or information via Yahoo!'s web service
APIs or via RSS or any similar XML or related feeds both on and off
Yahoo!-controlled web sites.


--Q: Really? In other words if I consider the content from which I want to
extract terms to be sensitive, then I should not use YTE because they are
granted ability to parse their logs and sell my content to another entity and/or
distribute as they see fit across their user base?
