I have read several articles on Latent Semantic Analysis and Latent Semantic Indexing, all of them prove the importance of knowing the latent content for a certain subject or even for a search term. I have been looking for some time for an application to generate latent content. Anyone has an idea?

I don't know much about this, but i assume that you believe this is part of an SE algorhythm for indexing sites, comparing the contents of the sites and then deciding what pages would be returned in the results.
I may be missing something, but isn't all content latent content?
also, the LSA and LSI you refer to was patented in 1988, before the internet as we know it came into being. As twenty year old technology, actually, it wasn't even technology, is was concept, would it even be relevant today?

It certainly is: LSA has evolved in PLSA or Probabilistic latent semantic analysis in the mean time, and several derivates are used by all major search engines. You simply need some model to define which content is on an which one is of topic. PLSA related models seem to do the job. The trick is to find the backwards model: starting from the search term coming to the latent content; could be the holey grail of SEO. Haven’t found it yet though

Google has been working on LSI for some time now.
Search for the word zoo and check the results. All should be as normal, then invoke the LSI index by using the ~ symbol so that you now search for ~zoo
You will find a different set of results.

Google's LSI is not working as it used to earlier. The problem is with a limited set of data, most of these LSI engines work well. I have seen a beta version somewhere which displayed amazing results.
But consistent results with a large quantum of data is yet to show up.

We must stay informed. If Google suddenly let their LSI results in the wild, there would be a massive "Florida" style loss of rankings.

I think the latent optimization model based on PLSA as it is developed by the university in Leuven can be used for websites with topics where there is a high competition, and the top 10 position matters (read: costs a lot of money) Don't think this will be a wide spread application, think it will be selectively offered... no main stream…

I searched "Ranking Optimization of a Web Page by Means of Latent Models" and found a PDF on the Leuven website.
It's not exactly inspirational.
Is there a more up-to-date document you can point me towards?

Hi
LSI for sometime has troubled SEOs and ultimately became the part of bigger Google Algo but i suggest that Search Engine Marketing Experts should focus on next Google Hydrogen Bomb, i mean from then positions will be based on
Query Score & Profile Ranking.
Cheers!

interesting...
