A Semantic Search Engine could be described as an agent that allows users to search at the topic level. Once a topic of interest is identified, then drill down to the specific document. Semantics is been applied these days by search engines in a few closely related fields. A possible way, is by using statistical analysis to retrieve semantic matches to a query. With this approach, they are capable of providing relational results based on the topics and keywords given by the user, and help them in the process of narrowing the search to be more specific.
To outline the process, there are basically 3 steps to consider:
(1) User enters a search query, with a given number of words describing with the topic of their search is,
(2) The engine returns results matching the words user entered, plus adding suggested alternatives
(3) The second step repeats itself untill the results returned are satisfactory to the user.
Automated semantic tagging is also possible, when the topic of a given page is well known. In this application, dynamic categorization of topical information about a query is implemented without any human intervention. These categorizations could take place in real time or be maintained incrementally over a time period. This is possible because there are available cognitive objects and conceptual models to identify sense information. Then these could be precisely weighted and measured, to determine the relevance among variable words forms and grammars in multiple corpus of content. You could have a travel site wanting to optimize for "discount tickets" when actually your visitors are searching for "cheap tickets". Another thing is the timeline to achieve results, like in the short, mid, or long-term. No unrealistic expectations here. One way I like to approach this is to optimize by levels. For example, I will choose 3 levels of difficulty and select the according keywords.
As I achieve the easiest level, I move on to the next and so on. Results differ per competition volume and markets, but overall results prove it does work.
On-Page Factors.
The most important elements in the page are the Title, Headings within the copy and keyword focused content. Keeping your code compliant is also beneficial. On-page optimization a very important part of the process, but it is almost indirectly proportional with the competition levels for the given target keywords. So it is highly scored into rankings when present within low to medium levels, but less significant among high competitive terms.
Google's application of semantics goes beyond Adsense. Relational Search is now evident when returning results from their index. This takes place if you get search results alternatives based upon an initial query you performed or after pulling pre categorised phrases on a database. Not so generalized yet due to multiple current limitations like speed, scalability and others. Performance is getting better and better, but it will be a matter of years before the big search engines start annotating webpages purely by using semantic ontologies.
Semantic Web Search Engine
First of all what is Latent Semantic Indexing? Well it is a complex mathematical formula, but it is being used by search engines to help them determine what is the theme of the site.
It is now known that Google especially are giving more importance to websites that are closely themed, and this can be very effective for achieving a good position in search engine results.
Google when it visits a web page will not only look at the keywords included on a page, but will look at all the content to see the relevance of the content to the keywords.
This will help search engines to better understand the overall theme of the page.
Assuming you have done some keyword research using one of the keyword tools available, I personally recommend Wordtracker as I find the results more reliable. What is the next step to make website pages more closely themed?
The answer is to try to use as many of the results returned from the keyword tool in your content. This of course needs to be done so that the pages reads well of course.
Using this method, search engines are in no doubt as to the theme of the web page.
Google uses LSI to associate words for classifying pages, as opposed to depending only on the keywords of the past.
Another use of latent semantic indexing is in helping Google in assessing the write type of adsense ads to display on web pages.
To see what words Google thinks are related to a keyword for example, just do a search for any word with the ~ tilde key first. It is possible to get a list from Google of related keywords.
Use their keyword tool, it may provide new words that haven't been returned by the keyword tool you have used.
A list of results will be returned that Google say are related to your keyword.
Now to get top positions in search engines, it will be important to consider latent semantic indexing because of the close theming of pages will result in higher rankings in search engines.
There is nothing complicated with using latent semantic indexing for your web pages, it is a question of having closely themed sites with content that is related to one theme, so there can be no doubt as to the pages topic.
Another important point to consider is to make sure that you have the anchor text (the words in the hyper links) should vary. It is a good idea to use different words related to your main keyword.
Do not have all the incoming links pointing to one page. By varying the anchor text this will not only get more pages indexed, but will also help with the theming of websites.
For example if your main keyword is seo, you could use anchor text like search engine, search engines, search engine optimization.
First of all what is Latent Semantic Indexing? Well it is a complex mathematical formula, but it is being used by search engines to help them determine what is the theme of the site.
