More about LSI and SEO

Marie-Claire Jenkins (a.k.a CJ), the Author of Science for SEO has an excellent article How does a search engine know what words mean?

My favorite section from CJ’s post is:

“Language is very ambiguous (meaning can be misleading – more than one meaning) and so are the senses used by different people. It is not always possible for the machine to give a very precise solution because of this variance. In fact humans have been shown to be about 90% accurate. ”

It fascinates me as an SEO how contextual words can completely change the meaning of a single word. How human perspective can completely change a definition for a word.

CJ was also interviewed by Joe Hall at Marketing Pilgrim Where she explains Natural Language Processing in-depth for the layman. I didn’t realize search engines were using NLP since the 1950′s or how integrated it is in our everyday lives. Read the interview Understanding Natural Language Processing for SEO
