Hi Linas, the name "more"/"_more" and "less"/"_less" were inspired by the "that"/"_that" which the current RelEx is using, so that we won't miss the information that the comparative format of the adjective/adverb is "more+adj/adv." and "less+adj/adv." or not without looking up the dictionary, and the comparative grade can be known as "GreaterThan" or "LessThan" to create the "GreaterThanLink" or "LessThanLink" for RelEx2Logic rules, besides that, "compare" just gives me the feeling that is supposed to connect two parallel objects/events that are being compared. Anyway, I don't really think the name matters that much. For the example you gave, RelEx is expected to have exactly the same relations as you suggested with either name... 
```
I have fewer chairs than Ben.
==>
_more(chair, have)
_quantity(chairs, few)
than(I, Ben)
degree(few, comparative)

I have ampler chairs than Ben.
==>
_more(chair, have)
than(I, Ben)
degree(ample, comparative)

I have more chairs than Ben.
==>
more(have, chair)
than(I, Ben)
_quantity(chair, many)
degree(many, comparative)
```
Anyway, I'm happy to change the name to "_compare"...

Regarding to "_quantity(chairs, fewer)", shouldn't it be "_quantity(chair, few)"?
