While reading "Patterns in Unstructured Data" which is one of the readings for the topic Dimensionality Reduction, I remembered the sentence: James while John had had had had had had had had had had had a better effect on the teacher. I had read about this sentence many years back and reading about Latent Semantic Indexing just brought it back.

The English language does recongnize this sentence as a valid and grammatically correct English sentence. It would be interesting to understand how LSI works in this case, or even for that matter what will the this look like after the SVD (Singular Value Decomposition) a.k.a Bob's Magic Wand has worked it's magic.

If you thought this was an absurd word, chew on this: Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo

This is also another example of a confounding but very valid sentence from the English language.

These sentences work as a perfect example for the discussion on linguistics and semantics that we saw in class today. For now looking at these sentences, I'll just agree to go with the theory of the 'Bag of Words'. Makes my life easier...
