These Plagiarism detectors!

Are these plagiarism detector tools even 90% correct? copyscape, frase, quetext?

I read somewhere someone said the best way is to manually check a couple of sentences within inverted commas on Google.

For example: Let's say this is your article - Wikipedia is hosted by the Wikimedia Foundation, a non-profit organization that also hosts a range of other projects.

On Google search, put: "Wikipedia is hosted by the Wikimedia Foundation, a non-profit organization that also hosts a range of other projects". If results are found, then it is copied, if no results are found, then its original?

What do you think?

How do you double-check yourself?

I don't think Frase has a plagiarism detector. As far as I'm aware, anyway, and I've been using it for a few years now.

When I was at university we had to use Turnitin, which is pretty much the gold standard of plagiarism detection and is used mainly for academic purposes. But even then, we were told that just because something comes back as plagiarism, it doesn't mean that it needs to be changed or that it actually is plagiarised. Assessors had to look at the context of how things are used and whether it is just common phrases that are being picked up by the matching system. So no plagiarism detector will ever be perfect - especially if you're using quotes in your articles - they will always come back as plagiarised even if you're citing them correctly. What they're good at is seeing if you've copied some text directly into your own text.

Basically, what you should be doing is using a detector that allows you to check each sentence that has been detected individually, ignore the number and check the context of each "plagiarised" phrase. If they're common phrases or an important quote cited correctly (as long as it's not practically an entire article of quotes) then ignore it.

If your concern is duplicate content - in my opinion - the effect of a percentage of the article being "plagiarised" isn't really an issue. The main issue is if you're wholesale copying the entirety - or the majority - of the article onto multiple sites. Just getting 10-30% copied on Copyscape isn't an issue. And I definitely wouldn't waste my time copying multiple sentences into Google to check it.

But this is a good way to determine if the content is original or duplicated, right?

Not necessarily. It will do a direct match between what you copy and what's on other sites. So if you copy 4 sentences, and 3 of them are directly copied then it won't return anything, even though 75% of what you searched for was directly copied. Unless you did it sentence by sentence for every sentence of the article, which would take a ridiculous amount of time, it wouldn't be accurate.

I get your logic, but you're best off using a detector that shows you what it's found so you can see if it's just cited quotes/generic text that everyone uses, or genuine plagiarism.

yeah you should go with the plagiarism detector, as you cannot check a whole article in Google search using inverted commas.

is better to use plagiarism detectors, check everything will take time some time, but if you are willing to check sections manually you can add your comments and sue your own words so it looks more like something you are providing for your own knowloedge that copy paste still requires some and effort to do that.
