[RIF][UCR] Straw poll comments

The following comments of [1] are based on discussions with Derek Sleeman, Peter
Gray and Alun Preece.


First of all, we found it hard to comment on Sections 2.1 to 2.8, without
commenting on Section 1, since the latter should set some basic tones and
principles for the document. One of the most important principles is, like [2,
3] indicate, there are different classes of rules and accordingly different
classes of rule engines, and generally exchanging rules only makes sense, at
least in Phase 1, in the context of a class of particular rule engines. We
think this should be clear in Section 1; furthermore, we agree with [3] that
the classification of rules should be used in use cases.

Among the eight categories of use cases, we choose "No, this text is not okay
unless changes are made" for Section 2.1 and 2.2.


*Section 2.1* (No)

The role of rules is unclear in this use case. More specifically, it is not
clear whether rules are only used to help integration, or rules are also part
of the information to be integrated. In the former case, it is not obvious why
and how it is related to rule interchange. In the latter case, we should
clarify how useful a rule interchange format alone can be in solutions of
information integration, and how it can facilitate information integration.

*Section 2.2* (No)

This section should have mentioned that decision support is not rule engine
independent. That says, given the same set of rules, different classes of rule
engines can give completely different recommendations. Furthermore, we agree
with [4] that it is not convincing that the example given is closely related to
decision support. We suggest using other examples, such as personalisation
(i.e., supporting decision making by taking into account users' preference).


Greetings,
Jeff
