We need to provide linking axioms from GAZ to ENVO

These should be rdf:type/ClassAssertion links

E.g.

'Lake Nyar' rdf:type ENVO:lake

There are a variety of approaches

 1. manual curation
 2. parsing labels
 3. mining wikipedia
 4. use some external resource

The simplest cheapest approach is (2). E.g. "Lake Nyar" is a lake.

This will undoubtedly produce multiple false positives, we don't know how many 
until we try the experiment.

After the experiment we can try approaches (e.g. override list, using OWL 
axioms) to weed out incorrect assertions.

This issue was updated by revision r73.

added scoring scheme - longer words score more, use of 'of' adds a bonus (e.g. 
city of X), appearing last has a slight edge (e.g. glacier bay is a bay not a 
glacier)
only select best match

Note:

ENVO EXACT synonyms are not reliable enough to be used here.

E.g. "islands" not be an exact syn for "island". Use PLURAL tag. "Canary 
Islands" is not a single island.

Consider adding a new term "collection of islands" or "island cluster" (not 
necessarily an archipelago)

However, we have many missing links because we are not using exact syns.
For example, the many GAZ terms that end "Trench" are probably "ocean trenches" 
(but not all).

Probably better to use rules here. E.g. if a path to GAZ:00000590 ! Oceans and 
Seas, AND ends in "trench" then it is an 'ocean trench'

It would help if we added more synonyms to Gaz. E.g.

Add synonym "amphoe" to "second-level administrative distrinct" (maybe add Thai 
language tag? But it's not really a language distinction I think). Same for 
"tambon". See http://en.wikipedia.org/wiki/Tambon

It would be useful to have collections in envo:

 * chain of islands
 * chain of lakes
 * chain of hills

..

@ #12 and #14
"archipelago" may also refer to the stretch of water that contains several 
islands. Is this the concern? The term is used interchangeably with island 
group or island chain, however. Perhaps we can replace "archipelago" with a 
class like "island chain", but keep the archipelago term as a broad or related 
synonym?

We do have "hill range", "montain range", etc. Are these terms not appropriate?

I was naively assuming archipelago = mereological sum of islands, but it makes 
sense it can be the sum of islands plus water in the region, i.e. the whole 
connected region. I think it's fine to go with this definition, whatever the 
experts say. It would be good to be precise in the definition.

#12 - here is an example:

[Term]
id: ENVO:00000098
name: island
...
synonym: "islands" EXACT [Geonames:feature]

I don't think it's good to include the plural form as a synonym. However, where 
this is done, I think it is good to tag this. E.g.

synonym: "islands" EXACT PLURAL [Geonames:feature]

#14

I retract this suggestion for now. I think existing "range" terms are much 
better than making abstract disconnected mereological sum classes. (the ranges 
could still be defined in terms of a mereological sum plus connecting "tissue" 
- sorry can't help but think in anatomical terms - but this would be more in 
the background)
