"Silver Bullets" / Check Type: Word-to-Word VS Re-Written
« on: September 18, 2015, 12:32:09 AM »
Plagiarism Detector team is proud to announce the absolutely awesome feature added to Plagiarism Detector – presets for different kinds of documents are now available “out of the box”!

Some theory behind this:
It has been some time, since we first observed cases, when our usual Plagiarism detection algorithms provided unsatisfactory results for certain documents. Additional research highlighted some common features for such cases. These are the specific features of the text in the Arts subjects and Exact Sciences subjects, as we started to call them. While the language for these documents is the same, they usually have some very interesting characteristics, which require different attitude from the Plagiarism detection algorithms.

So, starting with version 885, a user can select the preferable algorithm of check in the Step-by-Step Wizard! Please select “detect Text Rewrite (maximum detection)” if you documents are in the Arts subjects or other similar, and “detect Word-to-Word (maximum exactness)” if your documents are in the Exact Sciences’ fields.

We really believe that this new feature (that we have never seen before elsewhere) will help our customers in the ever-ongoing struggle against copy-paste!

We are aware of the false-positive Norton alert about the setup-file (at the time of posting, v885).

You are most likely to see the WS.Reputation.1 as the alert reason. It looks like Norton react to our file, as we have released a new version and their anti-virus software is not "familiar" with it.

You can read more on the problem here:
http://community.norton.com/forums/clarification-wsreputation1-detection

There should be an option to remove the file from Quarantine, which would allow you to use it.

We are sure the install package for our software does not have any virus inside, as the online-service confirms:
https://www.virustotal.com/en/file/e500af153be86bd6ce305f1440f04f183a38eff8b059b04bcae01937dd59c4eb/analysis/

We see it possible later setups can also be falsely detected, so client are encouraged to use VirusTotal for checks.

We hope it helps.

For the version 848 there is a problem when there is just one report shown in the list of the reports and this report is opened each time any document is checked.

It happens when there are more then 200 reports in the report folder. An easy way around is moving older reports in a separate folder.

This will be fixed in the next version released.

8
We have received several requests regarding references in the footnotes of the docX documents not being detected.

The problem is this: text from footnotes is not extracted. It is easy to check - no links that are present in the footnotes, are present in the report. We can do nothing here, since even Microsoft iFilters don't do this.

We recommend adding all the links from footnotes in the end of the document as text. For example as a list of used resources. In this case it will work just fine (remember to have URL-references enables in the program).

I hope it helps.

Over the time of our work in the field of Plagiarism Detection we have answered a lot of questions like "Are our documents stored elsewhere?". The answer is always the same: Your documents don't leave your computer during Plagiarism Detector checks.

But not so long ago a user started a more general discussion about the safety of such products in general. Safety for Your Documents, for sure.

With a permission from that kind person, I will publish our conversation here (with little edition). It may be useful for those worried about the problem.

User:

I have a question regarding this software..

If I make a test with my documents to test against plagiarism? Why my documents and my scientific works must remain on the server online
stored? This software must be 100 % confidential. No need to upload my scientific works on the server and stay there permanently.

PD Team:

No checked documents leave your computer when searching for plagiarism (except for fragments used for a search itself), nor do we have any database at our side with users' documents. Thus your documents are confidential.

You  may have misunderstood PDAS software description. But PDAS is a software that a client can use to store documents in his own database and check against them. It is not used for Plagiarism Detector Internet check.

User:

That's why I asked because has hovered the suspicion that these softwares for against plagiarism take us the documents which we scan with these softwares against plagiarism and you receive and publish them before us and upload them on the internet.. It is not good with our work.
On many websites people complains regarding this thing. And many do not want to scan for against plagiarism for this reason, because they worked in vain and software developers receive all scanned documents and they publish them or upload on the websites.
It is intellectual theft.

PD Team:

We didn't do any research on the way our competitors work, but we can assure you that no documents leave your computer during check with Plagiarism Detector.

The thing you are worried about would seem rather counter-productive for any service that takes care of its clients. Thus the first risk-factor I would predict is "free of charge". Meaning that I wouldn't trust any plagiarism-check service that is free to all. As a question stands: "what's their interest then?".

But for any serious and well-established service a revenue lost from unsatisfied customers leaving (and making bad PR) would be of more importance then their documents. At least I believe so.

Once again: with our software no documents leave your computer to be stored elsewhere.

As you have raised a serious problem, I kindly ask your permission to publish this conversation (text only, no names) on our forums, as it may be of interest for other people.

User:

I raised this issue because, as I said, has hovered the suspicion that these kind of softwares of against plagiarism steal our PC documents, scientific works etc, when when we add in the software the document and check and scan the document.
And now, I don't just mean just at this software Plagiarism Detector. Generally this kind of software that checks if the document is plagiarized or not, people worryes, that their work would be compromised in vain due of intelectual thieft, ie, the thieft of the software..
Yes, you can use these phrases and put on the application's forum, but without my name or my e-mail. Thank you in advance!

PD Team:

Well, I totally understand your concerns. So let me analyze the risks from my experience.

In addition to the already mentioned "free cheese can be a mouse-trap":

1. Software installed at your computer is more secure then some Internet-site, providing the check service. All the following is said about an installed software, since noone knows what happens server-side.

2. Having a certain skills, you can check what data leaves you computer during the check. I can't go into the detail of the algorithms we use, but to my knowledge one cannot reproduce the document with those search-requests generated by our software. Besides, any traffic-analysis will show the requests are going to different places (since several search-engines are used), thus separating the fragments even more. If such analysis shows a whole document uploaded somewhere in one piece -  it doesn't look secure.

3. Easier way: if a software is observed to heavily-load the CPU - it is working on your side. If the CPU is not loaded - the software is either not so good, or the document is uploaded to some server and is checked there. Evidently, less secure.

4. Additional data. You can always check the Internet for third-party sites mentioning the software you are interested about. The more "serious business" it looks - the more secure it is likely to be. As I have said before - one is unlikely to risk his profits from a well-established business with stealing clients' intellectual property. But if the site looks like a home-work of post-graduate student and noone has ever heard of this product before - well, use it at your own risk.

Besides, I have just consulted our RnD about this and they did provide some additions from their perspective:

1. It is rather unlikely that clients' works are stolen for their scientific value. More likely as a part of regular process of filling the database that documents are checked against. For a widely-used service it looks impossible to analyze all the incoming documents for scientific value.

2. Indeed, some services do store all the documents that are checked with them (we don't see it right to mention them). You can follow the  above mentioned list of criteria to reduce the chance to use such a service. Even if the service stores clients' documents, there are two options: documents are stored for the service internal use only (later documents are checked against old ones) or documents are later indexed by search engines, which is indeed a serious threat, as you document becomes publicly available.

3. Someone interested in a detailed research in the field can make a set of "trap-documents" that are 100% original and check them with different services. Then in about 1.5 month repeat the same. If a document remains 100% with the same service - no documents are stored. If it is found plagiarized by the same service, but none of the others - documents are stored in the internal database. But if different services start finding plagiarism in a clean document that was checked with once service only - those services are just mirrors of a singe document-storing server or the document became publicly available.

We hope you find this information useful.

FAQ - Frequently Asked Questions / Exclude/Include lists
« on: January 13, 2014, 03:44:17 AM »
At the last page of the Step-By-Step Wizard you can open the second tab, which is Exclusion lists. It allows you to edit two different list, giving specific details for the search engine.

Exclude list: if any exclusion mask in this list is present in the found page URL - the page is ignored during check.
For example, adding the title of the document to the list will ignore all the Internet sources, that use the document name in the page address.
Example:
If the exclusion list contains "wikipedia" then ALL URLs to wikipedia.org will be ignored.

Include list: any URL in the list is thoroughly checked against during the search.
If you expect the page to be a source of part of the checked document, but the software does not find it, you can add the page to this list, to make sure it is checked in detail. The fact that the document is not detected without it can be explained by the SEP-stage fast check, finding candidates for a REP detailed comparison, is not so specific and detailed, but relies on the quantities of sites checked.

12
+ "Detect URL references" now works fine. If a document contains a section with a direct link to the Internet page containing it - the section is marked as Referenced (if the check-box is checked)
+ Exclude list now works as intended: if any word in this list is present in the found page URL - the page is ignored during check
+ Include list now works as intended: any URL in the list is thoroughly checked against during the search.
+ "Check against folder of documents" will now always ignore the file that is checked, if it is contained in the same folder.
+ Improved PDAS compatibility.

Planned for the next minor release: faster loading of Available Reports list.
