how to code related articles automatically?

[DeLaVega]

Hi, I'd like to have in a website related articles to a specific one, like a lot of sites and online newspapers have.

Do they do this automatically? Is it possible? How should I do it? (I'm thinking and looking for a strategy)

Thank you a lot

I reckon some do it automatically and probably some don't.

Programming wise it's not that hard to do, it depends how proficient a developer you are. If you're using wordpress, there is a plugin available which does it for you (http://wordpress.org/extend/plugins/...-posts-plugin/) and I'm sure most other blogging platforms have something similar.

Thank you!

It's a customized development, so I'd like to know about the logic I should use for generating automatic related articles.

Thanks!

It's similar logic to a search engine really, get all the terms in the title of the post and then search against an index. Zend_Search_Lucene would probably be useful for this.

Let me see If I understood well.

For example if I insert a new article called:

"The life of the butterfly"

I should insert in a table all these words (maybe excluding "The", "of" and common words) and link it to the article row in the articles table?

Thanks a lot
