How can I use php to categorize different keywords, for example, to look at shoes, boots, nike, etc. in similar categories.
Any code would be appreciated.
(Warning: fundamentalist approach) Go to http://commons.media.mit.edu/ and http://www.cyc.com/cyc/opencyc . These are two open commonsense databases. Do a few searches for the categories you are interested in. You will get some related terms for each category. Put it in a fast database to your liking and you are set up.
