By building sites and writing articles with LSI theory and principles in mind you're sites are going to come off as more authority than those who are using the traditional keyword-targeted article model.
If you researched then you'd know the benefits so obviously you havent researched enough.
Yes, maybe I need to do more research.

The reason I asked the question is because I've come across numerous SEO gurus and websites proclaiming the benefits of LSI and promising to be able to use "LSI theory and principles" to create supposedly LSI-friendly websites. However, I doubt half these self-styled gurus touting the Next Big Thing in SEO have ever performed even the most basic of Singular Value Decomposition (SVD) calculations that is a prerequisite to LSI.

The reason this seems like snake oil to me is because a search engine is represented, in LSI terms, by a term-document matrix of many billions of documents. The LSI scores are therfore a function of the co-occurance of terms/keywords in this global corpus. Therefore, the only way in which a person could possibly attain the sort of influence some of these SEO gurus and companies promise would be if they were somehow able to alter the scores of all the other documents in the matrix (unlikely).

I could, of course, be wrong in my understanding of LSI.

Anyway, as you said, this thread isn't about LSI so I'll leave it there
