Typologies and Taxonomies: An Introduction to Classification Techniques
I’m not rating this because I didn’t understand it, and I don’t think I was the audience for it. I was approaching it as something for editors and content managers, but this is a book for statisticians or research scientists. There’s a lot of math here, and it’s geared towards the classification of large datasets based on the correlation of variables (I think, anyway).
It’s short, so I did read it to the end because it revealed some aspects of classification I wasn’t aware of. So, helpful in that sense.
