Dear Dr Deepthi Balla . I usually use Turnittin software. It very good.

Turnittin software is best, but unfortunately not free

Turnitin- is mistly used in Indian Universities as per the review. But I read in the reviews that it doesn't do accurate plagiarism check. Just does text to text comparision.

I am just stating the review here. It would be helpful if you can express your previous experiences with using any software you suggest. Please forgive my request if it offended any. I am so thankful to you all for giving such tremendous replies and support.

I will be checking each of the suggestions you give me here.

Turnitin is the best software but you need to pay for it

There are many avaiable online, But not very good.

If you dont have a subscription, ask your friend etc. to check it for you. It just takes few minutes.

Prof. Deepthi Balla: In my opinion, most of the free-software-checkers for plagiarism don't work effectively. Since there is no guarantee that the original content of your manuscript might not be copied and sold to others before it is published by you, I discourage using any free-software-checkers for plagiarism; some of them are betrayers.

• WARNING 1: There are a massive number of betrayers!
• WARNING 2: Plagiarism is a sin! If it is, severe action may be taken and/or legal notice may be given.

Unfortunately, you have to pay for the sake of getting good results. In any way, it is not well for your reputation if there were accusations of plagiarism.

In my personal opinion, free anti-plagiarism software is not safe.

On the other side, my university, WISE, uses the TURNITIN plagiarism checker. The maximum allowed percentage of plagiarism should be commonly less than 20%. However, from the same reference, it should not exceed 5%.

We must completely understand that the plagiarism is never allowed and it is almost impossible to have 0% similarity.

Dear Prof. Deepthi Balla & all the honorable researchers,

Plagiarism is a common problem facing almost all professors. This respected portal (i.e. RG) defines plagiarism as:

The term “plagiarism” has different meanings, but it usually includes copying somebody else’s work without permission.

On the other side, self-plagiarism is when the author republishes portions of his/her own previously written research work while authoring a new work.

I may be somewhat old-fashioned, but please have a look at the following golden principles on how to avoid plagiarism in academic writing, especially Self-Plagiarism:

Now, I think that the above-mentioned rules are helping in setting boundaries to avoid plagiarism in general, and self-plagiarism in special.

Finally, believe me, or not: If you make one plagiarizing, you may solve one problem and fall into many others where some of which may be described as a knockout. Again and again, please always remember that if there were accusations of plagiarism, it is not well for any researcher's reputation, in any meaning.

Dear respected colleagues,

Related to this valuable discussion thread of Prof. Deepthi Balla, please let me point to another critical issue related to plagiarism software-detectors.

My friend was accused of plagiarism. Why?

After about five months, his promotion process to associate professor was rejected because of plagiarism. When he checked the promotion report, he found that one of his papers was accused of plagiarism and with a 100% percentage. The reason is that his manuscript was checked by his co-author using one of these checkers. It took him several months time of following up to solve the problem and removing the manuscript from their database. After that long period, he re-applies the promotion order for the second time.

Therefore, plagiarism software may retain a copy of the manuscript in its database. To state the truth, this is depending upon the settings and type of account subscription.

So, you may face a similar situation when you submit your manuscript after plagiarism checking to a journal. It may be rejected instantly because it would show up 100% similarity index.

To solve the problem, it may take several months time of following up and removing the manuscript from their database.

If there were accusations of plagiarism, it is not well for your reputation, in any meaning.
