Even inside those semantic domains, problems can come up. Take plant classification: you've got hundreds of unfamiliar groups, and scattered among those are a relatively few groups that contain the more familiar plants. Also, these hierarchies can be wildly unbalanced. Ginkgo is a whole division of the plant kingdom all by itself, while three levels deeper on the hierarchy, the family Asteraceae has some 23,000 species according to Wikipedia. I was browsing around at random on Wikipedia today and ran across a page on the controversy over the classification of babblers (Timaliidae), which reminded me of the problems I ran into when making the taxonomy for Eklektu. At the time, I thought a classification would be useful in defining the meanings of words and the boundaries between one and the other, by defining a particular example as representative of the group, and using the classification to set the boundaries. But then it turns out that the groups in the classification are not as well delineated as you assumed.

Yahoo used to have a classified index of web pages (and perhaps still does; I haven't used it in a long time). I found it useful for finding pages when I was trying to learn Japanese. Wikipedia's categorical index can also be useful, although it can be haphazard in places. I still use categorical word lists for my recent languages, which can be useful for later clarifying the intended meanings of words if you weren't careful enough in the first place, or finding words of similar meaning.
