There is one thing which confuses me with the use of multiple broader terms and classification.
Suppose I have the following thesaurus:
> colors
> green
> red
> blue
> yellow
> orange
> favorite colors
> orange
> red
> yellow
where the concepts orange, red and yellow have two broader concepts: favorite colors and colors.
What is the effect then if I give a document the concept 'orange'? Can I make the difference between 'favorite color' and just 'color'?
