Latent Semantic Index

Hello Guys,

What is this latent semantic index? When I attended for an interview interviewer asked this question to me. I hadn't any idea about this.
Please give me some ideas about this.

Thx

 

Latent Semantic Indexing (LSI) is a unique information retrieval method developed that improves your ability to find applicable information. Using a powerful and fully automatic statistical algorithms LSI can retrieve relevant documents even when they do not share any words with your query — concepts replace keywords to improve retrieval. Latent semantic indexing adds an important step to the document indexing process. In addition to recording which keywords a document contains, the method examines the document collection as a whole, to see which other documents contain some of those same words. LSI considers documents that have many words in common to be semantically close, and ones with few words in common to be semantically distant.

 

Nice copy and paste

LSI is a system that looks at all the words within a document and try to associate it with a meaning or intent.

For instance take the word "apple". Apple could be referring to the fruit or the company.

LSI keeps a record of what other words appear often around other words.

So if a spider finds the word apple and the word ipod or computer in the same document, because of it's vast database, it knows that this sort of thing is common and can figure that the document is about apple the company and not the fruit.

That, as far as I know is what LSI is all about.

 

based on my own experience, LSI is very effective on my SEO campaign. Because I believe that LSI belongs with their algorithm.

 

you were asked about it in a company ? was it a seo one ?

 

yeah it was a SEO company

 

Thank you very much T_Media. you has given a simple description about LSI

 

How can I check my document through LSI??? is there available any software or help??

 

Based on my own experience, what you just said makes 0 sense and you are just trying to get your post up.

 

Latent semantic indexing adds an important step to the document indexing process. LSI used by search engines to determine what page is about outside of specifically matching search text….

 

Providing your writing content that is naturally written you dont need to worry about LSI, it will come naturally

 

xD, lol, exactly what I was thinking.
