SEO and LSI – How to Use Latent Semantic Indexing

People get worried when they hear about terms such as SEO and LSI, and when they try to find out how to use latent semantic indexing, they get even more worried when they get conflicting messages. On the one hand some say that LSI does not exist and therefore can not be used, while others, on the other hand, state that it is critical to your website's success with the search engines.

We all know what computer people are like, the way they try to make acronyms of everything. LSI is one of these, although not quite what you would call an acronym. LSI does exist, but not in the form that Google would have us believe, and not in any form that you can use to make your website 'LSI compliant'. Anybody claiming that they can do that are simply playing Google's trick and using big names for what is a very simple thing to do.

LSI or LSA?

Without going into any detail as to the mathematical background of LSA, it can be used and is used, to determine the relevancy of a passage of text to any given topic based upon a keyword or multiple word search term. LSA was, incidentally, patented by a group of people in 1988, although the basics were known prior to this. LSI is nothing more than the use of LSA in the indexing and retrieval of information. It is therefore a concept, and you can not make a 'concept compliant' web page.

However, it is all semantics (ha-ha!) And the meat of this article is not to knock holes in the way the terms LSA and LSI are being wrongly used by SEO experts, but inform as to how you can make your web page more likely to be considered relevant to the main keyword for which you want your page indexed. This is very simple and does not warrant all the books being being offered on the subject.

The Development of AdSense

Latent semantic analysis is used by Google primarily to detect spam, in respect of excessive repetition of keywords in order to fool the search engines into providing a high listing for that keyword. There was a time when smart people could indeed achieve this simply by writing a meaningless template with rotating synonyms into which any keyword could be multiply inserted by means of software. Thousand of pages could be generated in minutes, each targeting a different keyword. Some were making $ thousands daily from AdSense using this method.

In fact the principles of LSA to determine the content of web pages were used by a small company called Oingo that changed its name to Applied Semantics who developed a search system to determine the relevancy of page content for specific advert placement. They called this Adsense. This company was in turn bought by Google in April, 2003, and AdSense used to replace their own system which was still under development. Adsense, then, was not developed by Google, …

Continuing Strides in the Research and Technology of Solar Energy

At this time the research being done in the matter of solar energy, finally reaching at an increased rate towards advances we have never seen before. Much has to do with increasing reports and warnings by the media that we need to conserve power and energy. People are really starting to take this seriously ad if you are reading this article you are involved. You are considering solar energy too.

Current research in solar energy ha much to do with technological options and test facilities – we could figure out more about generating solar heat into energy if we had even more space in which to do so.

For example: The "Power Tower"

The power tower is a system of generating solar power by method of a large sequence of mirrors. The mirrors can then, when in the correct position, generate a vast amount of heat. Heat is then the vessel between light and energy. The technology has allowed these power towers to track the path of sunlight that will generate the most heat.

This prototype, the amazing power station, unfortunately emphasizes the centralized system of generating energy.

Of course, there are many other types of research out there that continue to improve our ability to collect and power. We may possibly be near the day when naturally everything can be powered with some kind of solar light. Other methods, more democratic methods for obtaining solar energy are being technology improved as we speak.

Everything from glass panels to mirrors to extreme interior design, solar power must be compacted and contained. The challenge, of course, is and always will be the method of transforming sunlight into energy by collecting the solar cells prove to us that are decentralized by nature. If solar cells function only a when collected and condensed they must be controlled.

Failing to collect enough solar cells, naturally results in failure to generate solar power into any significant amount of solar energy. Things such as solar powered lights, pool heaters, home systems, solar ovens and more, however, are already in our grasp, so try a solar energy system. You will be glad you did. …
