plagiarism checking script for article directory in PHP ?

Hi

I have an article directory. I am facing problem of plagiarism Authors are submitting UnOrignal articles in a large number daily. It is very difficult for me to check them one by one of copyscape and grammarly.

Please can you guide me how can I develop a piece of code in php that check an article before interting in database for plagiarism If text orignal Insert in database other wise not.

I have good php programming skills I can code what ever that will be, but I am thinking where to start which technique will be used.

There are lost of directories those have build-in plagiarism checking system like ezine.

Please share your ideas about this with me I shall be thank full to you

 

The CopyScape http://copyscape.com/premium.php has a premium service where they allow to use API to check if the page isn't plagiarised. I do not know if there are any free scripts that do this out of the box, since you need to have Internet indexed first before you can do a search for duplicate content.

 

copyscape API becomes very expensive when a guy submitting same article again and again. Or submitting unoriginal contents in hugh number. I suppose it will cost me 100$+ daily which is un affordable.

I want to build a system just like ezine use.

 

Good recommendation! Check copyscape like Greg said... Im a member of copyscape & its great!

iam also looking for same script... but less expensive then copyscape

 

If you can't use CopyScape, then you can always try searching in Google. Just search for a sentence in the first paragraph of any article surrounded by quotation marks. You'll be able to find any copies of the article that way.

 

mmm ... that's right u can use the premium account.. very difficult for check php plagiarism or copyscape ...

 

But, premium membership of copyscape costs you 5 cents a search, i.e. 1 USD per 20 articles if am not wrong; This 20/$1 API can easily be integrated using PHP (if that is not costly for you).
Besides, my team can build you a system that can do the job though.

Hope it helps.

 

you can try Google CSE API , which may not powerful as copyscape buy it's free , here the sample tool using CSE API : Plagiarism Checker
