Do I need to give credit to the original writer if I rewrote something in my own words? Situation Suppose I have built a computer program which fetches articles from websites, rewrites them and posts them. Since I'm rewriting the article I think copyright law is not violated since information can not be copyrighted on its own. Questions Do I need to give credit to the original article writing website even after rephrasing the article? Can websites declare web scraping to be illegal? What if the program mimicks the human behaviour?
Ideas are not Subject to Copyright Copyright does not protect ideas. This is true in the US, in the UK, and under the copyright laws of every country that I know of. Article 2 paragraph 8 of the Berne Copyright Convention reads: The protection of this Convention shall not apply to news of the day or to miscellaneous facts having the character of mere items of press information. If the ideas of a work have been so re-written or recast as not to constitute a derivative work, the original author has no rights over the new work, which becomes a separate work with its own copyright. In such case there is no legal requirement for any credit or acknowledgement, at least not under copyright law. Also the use of a work whose copyright has expired, or is for some other reason in the public domain and not protected by copyright, may be legally made without acknowledgement of the author, or even under a false designation of authorship. Plagiarism Passing someone else's work off as one's own is generally considered to be plagiarism. Some people consider that using significant parts of another's work without proper credit is also plagiarism. Plagiarism is not a legal matter. It is considered highly improper in the academic and journalistic worlds, and may carry serious consequences there. It is considered unethical by many in other situations as well. However, it does not constitute copyright infringement, and copyright law cannot be used to prevent or punish plagiarism that is not also infringement. Works Created by an Automated Process or Script Whether an automated process can (at the current state of the art) truly extract facts and re-express them to a degree that would constitute a new, non-infringing work, I tend to doubt. Whether even sufficient alteration could be made by an automated process to reliably constitute fair use, fair dealing, or have any similar exception apply I also doubt. The US Copyright Office Compendium of Copyright practice (an official publication of the US Copyright Office) states in item 307: The U.S. Copyright Office will register an original work of authorship, provided that the work was created by a human being. The copyright law only protects “the fruits of intellectual labor” that “are founded in the creative powers of the mind.” Trade-Mark Cases, 100 U.S. 82, 94 (1879). Because copyright law is limited to “original intellectual conceptions of the author,” the Office will refuse to register a claim if it determines that a human being did not create the work. Burrow-Giles Lithographic Co. v. Sarony, 111 U.S. 53, 58 (1884) Similar legal limits on AI authorship apply in many other countries. Fair Use Fair use is a specifically US legal concept, and generally does not apply in any other country, although I understand that Israel has closely followed US law in this matter. Fair use is defined by 17 USC 107. That law specifies four factors which a court must consider in making a decision on whether a use is a fair use. particularly important is whether the new work will harm actual or potential markets for the original, and whether it will serve as a replacement for the original. US Courts also often consider whether a new work is &quot;transformative&quot;, that is whether it serves a significantly different purpose than the original does. For example, in a popular song, lyrics are often intended to have an emotional effect. In a textbook on verse, the same lyrics may be used to demonstrate poetic technique, rhyme, meter, etc. That would be a transformative use. The presence of proper attribution or credit is often a significant factor in the decision by a court as to whether a use is fair. Using another's work without proper credit is significantly less likely to be found to be a fair use, although credit is not an absolute requirement of fair use. See Is this copyright infringement? Is it fair use? What if I don&#39;t make any money off it? and the various questions on this site tagged fair-use for many more details on fair use. Fair dealing and Other Exceptions to Copyright In the UK and some commonwealth countries, there is a doctrine known as &quot;fair dealing&quot; It is somewhat similar to fair use, but is generally more limited. In other countries there are various &quot;exceptions to copyright&quot;. Some countries have a few broad exception, some have many narrower exceptions. India, for example, has more than 28 separate exceptions. What is covered varies from country to county. Exceptions for teaching, comment and analysis, and news reporting are common. Article 9, paragraph 2 of the Berne Copyright Convention (linked above) recognizes such exceptions, stating: It shall be a matter for legislation in the countries of the Union to permit the reproduction of such works in certain special cases, provided that such reproduction does not conflict with a normal exploitation of the work and does not unreasonably prejudice the legitimate interests of the author. The convention goes on to state, in article 10, that: (1) It shall be permissible to make quotations from a work which has already been lawfully made available to the public, provided that their making is compatible with fair practice, and their extent does not exceed that justified by the purpose, including quotations from newspaper articles and periodicals in the form of press summaries. (2) It shall be a matter for legislation in the countries of the Union, and for special agreements existing or to be concluded between them, to permit the utilization, to the extent justified by the purpose, of literary or artistic works by way of illustration in publications, broadcasts or sound or visual recordings for teaching, provided such utilization is compatible with fair practice. (3) Where use is made of works in accordance with the preceding paragraphs of this Article, mention shall be made of the source, and of the name of the author if it appears thereon. Thus article 10 paragraph 3 of the Berne Copyright Convention establishes an international norm that works used under an exception to copyright, such as fair use or fair dealing, shall be properly credited. Web-Scraping The law on computer scraping is still under development, and varies from country to country. If a site operator makes it clear to users that scraping is unwelcome, it may be unlawful, depending on the rules of the country or countries involved. When a Terms of Service (TOS) document constitutes a binding contract or agreement that users must accept, and when such an agreement prohibits scraping or other automated access, that prohibition may be enforceable. in Craigslist Inc. v. 3Taps Inc., 942 F.Supp.2d 962 (N.D. Cal. 2013) a US Federal district court held that sending a cease-and-desist letter and enacting an IP address block is sufficient notice of online trespassing, which a plaintiff can use to claim a violation of the Computer Fraud and Abuse Act (CFAA). However, that decision has been criticized by many, and was not a Circuit court or Supreme Court case. In the recent case of Van Buren v. United States, 593 U.S. ___ (2021) the US Supreme Court narrowed the application of the language in the CFAA making access that &quot;exceeds authorization&quot; criminal. In the case of HiQ Labs, Inc. v. LinkedIn Corp. The Supreme Court addressed the question of whether scraping a public website after a cease-and-desist letter has been sent constitutes a violation of the CFAA (this was the fact pattern in Craigslist v. 3Taps). The Court sent the case back to the Ninth Circuit for reconsideration. The Ninth Circuit Court reaffiremd its prior decision that when the website had been made publicly accessible, the CFAA did not apply, even in the face of a C&amp;D letter. This seems to overrule 3taps. Note that other means of prohibiting scraping may still be legally sound and enforceable. See &quot;hiQ Labs v. LinkedIn&quot; from the National Law Review. (This article and the decision it reports was brought to my attention via a comment by user Michael Seifert.) The article &quot;Web Scraping Watch: Cases Set to Clarify Application of the Computer Fraud and Abuse Act&quot; discusses these cases in more detail, but does not incloude the latest ruling in the HiQ Labs case. Conclusion Unless the results of the &quot;rewrite&quot; done by the &quot;program&quot; are sufficiently original to be neither a quotation, a fair use, nor a derivative work, but a new work using the same ideas, they will need to qualify under fair use or some other exception to copyright (unless permission has been obtained). This may well require a proper attribution of the original article. In any case, such credit is considered to be ethically mandatory by many. The web-scraping done to obtain the initial data may or may not be lawful, depending on the contents of any TOS document, and whether the relevant laws make such a document enforceable, which is still not a fully settled point under the law, and which varies by country. Personally, I would think giving proepr credit much easier and safer than trying to justify not doing so, but that is not law, just my opnion.
The notice has a lot to do with legacy requirements in the United States to claim the copyright to a work. Up until 1989, the copyright notice was required. Today, the statements are mainly maintained to protect against "innocent infringement" which might reduce what a content owner can get in court. What exactly do those terms entail? That the owner stated owns all rights and you may do nothing with the content. My biggest concern is this: by writing that, is the company claiming to own everything on the website, even potentially copyrighted user-submitted material? That's exactly what they are doing. Depending on the terms of the specific site, content contributors generally either assign copyright to the site owner or license the content in a way that allows the site owner to do exactly what they want with it. Site creators with the smarts or money to do it right/get someone to do it right usually state something like: Copyright [Site Owner] and contributors. Other sites (like this one) state specifically what they hold the copyright to: site design / logo © 2015 Stack Exchange Inc THIS IS NOT LEGAL ADVICE. CONSULT AN ATTORNEY REGARDING YOUR SPECIFIC SITUATION.
There is no special exemption where academic work is unprotected by copyright. You can quote from academic sources to the same extent that you can copy from non-academic sources, without getting permission. In fact, it is legally impossible to tell if a source of &quot;academic&quot; versus &quot;non-academic&quot;. Attribution is not particularly relevant for copyright, what matters is permission (when required). It may be that a copyright holder will grant permission for an extensive quote provided you attribute the source, and it may be that academic publishers or authors are more willing to grant permission than other publishers / authors. On the other hand, many academic works are very expensive, so that distributing the text for free may have more &quot;effect on market&quot;, and may result in disinclination to grant permission to quote. On the third hand, such quotes are more likely to be squarely directed at the &quot;commentary&quot; motivation behind fair use law. The point here is that there isn't a special law about just academic sources.
You are in general correct, KBurchfiel. A code snippet such as import math; or For i := 1 to 10 print i; has no originality, and is not protected by copyright. A post eplaining the meaning an usage of such a snippet might well be original enough to be protected by US copyright, indeed it probably would. But the code on its own would not be. Anyone could read such a post, and if s/he understood it, use the code snippet and not be in violation of copyright, not compelled to place the entire program in which such a snippet was used under a CC-=BY-SA license. The creative commons people would prefer that a CC license not be applied to a publication that is not protected by copyright, and if it is so applied it is legally meaningless. But they have no legal way to enforce such a preference. A stack exchange post that consisted of nothing but such an uncopyrightable code snippet, with no explanation r discussion, might well be downvoted or even deleted. But that is a matter of site policy on what is a useful answer, not a matter of copyright. Using an excerpt from a copyrighted work so small that the excerpt alone would be uncopyrightable, would probably be fair use under US law, and might well be fair dealing in UK law. Something that is fair use does not compel the reuser to abide by the terms of a CC license, because those terms apply only when the content could not be reused without the CC license's permission. However, a code snippet does not need to be very much more original than the above examples before it becomes copyrightable. Whether it can be used via fair use rather than via the CC-BY-SA license is a very fact-based decision (the usual four-factor analysis is spelled out in 17 USC 107).. But if the snippet can be rewritten to express the same concepts but in a different expression, then there is no copyright issue, and again the CC license will not apply. If the snippet is complex and original enough to be copyrightable (a fairly low bar) and it is re-used unchanged, under conditions where fair use does not apply, then the CC-BY-SA license's terms must be complied with for the use to be legal. That is several &quot;IFs&quot; however. The exact details of a specific case will matter in such cases, there is not one rule for all snippets, all posts, or all programs.
You are in breach of Copyright. Plain and simple. Certain websites allow you to use the website content as long as a link is made, but the website must clearly state that. You may also use a tiny portion of the content if it falls under Fair Use, where "Fair Use" does not mean "I want to". The best thing to do is not to do it. You can't copy anybody's work without consent. If you're thinking about Google specifically then they offer multiple APIs so that you can use their content in a wide variety of ways.
It's allowed by the Creative Commons Attribution -ShareAlike license, and intentionally so. The Wikimedia Foundation wants things like this to be possible; that is part of the goal of open content. (This license is also used on Stack Exchange content, so the same applies to e.g. this answer.) However, it is important to remember that this is not a public-domain equivalent license. If you copy from a Wikipedia article (or an SE post), you must comply with the &quot;Attribution&quot; and &quot;ShareAlike&quot; requirements. Attribution: You must give credit to the author. For Wikipedia articles, which typically have many authors, a link to the page is sufficient; editors agree to this in addition to the license when they save their edits. For Stack Exchange content, a link to the post itself should be enough. (To get a link to a post, click the &quot;share&quot; link below the post.) ShareAlike: If you modify the content, you must release your modified version under the same or a compatible license. You can't copy this answer, add more information (or translate it into another language, or make any other change), and keep an all-rights-reserved copyright on it, or release it into the public domain; your version must also be released under CC BY-SA. As long as you follow these requirements, copying is allowed and encouraged.
If you create a new work that is derived from or based on someone else's work, it is a derivative work, and you cannot do so without permission from the original copyright holder. If the original work is made available under a CC-BY_SA 4.0 license, you have permission, but it comes with conditions. One of those is that you must attribute the original work -- you must say what work yours is based on and who created it. Another is that you must license your own derived work under the same CC-BY-SA license (or a compatible one). This does not mean that your work is not copyrighted -- it is. But it does mean that you must grant to others the same rights that the creator of the work you used granted to you. That is what the "share alike" or SA part of the license means. if you don't like that, you should not use a work licensed under CC-BY-SA terms to create your own work. If you publish your work but fail to grant that license to others, you are infringing the copyright of the work you used, and could be sued. Note that if you had created a compilation rather than a derived work -- for example if you created an album of images from various sources, some of them under CC-BY-SA licenses, you would retain a copyright on the collection as a whole, and that would not have to be under CC-BY-SA. But in this case you say that you used the other person's image as a background for your own illustration. That is creating an "adapted" or derivative work, i am fairly sure, and invokes the share alike clause of the license. You might also want to consider the different case mentioned in If I include an unmodified CC-BY-SA work in a book, does the whole book have to be CC-BY-SA?
Person A has to have created the data to hold copyright; for most kinds of data this has no legal effect because facts are not protected by copyright. A mineable database probably does not have the necessary creative elements for copyright. An algorithm is not protected by copyright (it might be patented). Person C's program is copyrighted. The product created by D is probably copyrighted, depending on what degree of creativity is involved in their transformation. If the transformation is automatic then no, but if creative judgments are applied to the output of the program then maybe. Though the resulting product is another database of facts, and the facts cannot be protected. In terms of "using the model", only C and possibly B have any control. If it is necessary to validate the software using A's data and A has kept the data secret, C might negotiate with A to use the data, in order to complete his program, and that could give A some interest in the program.
