We have to have some criteria based on which an evaluative statement about an ontology is produced, otherwise it might be labeled as a 'biased' opinion. Also, if we say every-ontology is good (which they certainly arent) that’s not productive either.<br />
<br />
[Barry's suggestions]<br />
<br />
Does it have a clear name?<br />
<br />
Does it have clear documentation?<br />
<br />
Does it have a clear subject matter?<br />
<br />
Are its assertions universally true <br />
(e.g. if it says A part_of B then is it true of all instances of A that they are part of some instance of B)?<br />
<br />
Is it used by other independent groups?<br />
<br />
[Nigam's suggestions]<br />
<br />
There are four main axes on which an ontology ought to be reviewed:<br />
<br />
1 - extent to which it satisfies the purpose for which it was built <br />
<br />
2 - ability to express what a user might want to express (use case tests) <br />
<br />
3 - ease with which one can express non-sense while using it (i.e. take a few hundred use case instances and see how many were actually meaningful)<br />
<br />
[2 and 3 will be at odds with each other much like sensitivity and specificity]<br />
<br />
4 - consistency checking (i.e. is the ontology formally consistent)<br />
<br />
[Barry's input on 4]<br />
<br />
These are two related questions: are there tools/methodology for checking? <br />
what is the result of such checking? (and if no tools, what is the <br />
result of a quick manual check?)</div>Jessica121
