Knowledge vs. verifiability[edit]

Your recent edits to nalidixic acid challenged the content of published sources without offering alternate sources. One of the pillars of Wikipedia is verifiability. Facts should be backed up by reliable sources. While you might be right, you need to be able to demonstrate it. Contradicting published sources without providing alternate sources is not the way to go about things. If you had a second source which contradicted the an existing source, it would still be inappropriate to say which one is correct. If it was obvious, the first source would be dropped in favor of the second, otherwise it is an opinion, and opinions have their own guidelines (n.b. the section, Assuming the 'obvious' ) and requirements for sourcing. You may well be right, and you seem knowledgeable, but you need the sources to show the other editors that you are right, especially, when a reputable journal contradicts your claims. I'll double check the journal and see if there was a correction, and check a few books.Novangelis (talk) 03:51, 9 September 2010 (UTC)

In response to your reply on my page, I've had a chance to look things up. I replaced the reference with one that specifies the naphthyridine structure as well as being discovered during the synthesis of chloroquine. I did not use the references you provided, since the Bayer website, while informative, is not an ideal source, and the book was not immediately available to me. There are some technical issues on Wikipedia. Never cite sources you haven't read (WP:SAYWHEREYOUGOTIT). I'm not saying you didn't, but I didn't. Also, don't use Wikipedia as a source for itself (WP:CIRCULAR) in articles. Of course, its fine for discussion. As an aside, the problem with the word "wrong" is that it is very negative and can be imprecise. In addition to the specific compound, the word quinine may also refer to a general class of drugs including both quinine and chloroquine, plus others. Here is a comparison of your version and what I did with it.
Thank you for your help on the article. Never worry about making "mistakes" in procedure—good info trumps nice formatting and things can be undone until the ideas are fleshed out and researched. Other editors can always tidy up, and the revision process may generate something better than the individual contributions.Novangelis (talk) 17:17, 9 September 2010 (UTC)
While quinines aren't a class of organic compounds, the term is used to refer to a group of pharmaceuticals. You will find chloroquine and primaquine described as "quinines" in the medical literature. Pharmacological terminology is often ambiguous. For example, anticoagulants are imprecisely called blood thinners although they do not impact viscosity. (On the other hand, statins reduce viscosity.) The important thing is you saw something amiss and brought scrutiny to it. Your approach might have been a little clumsy, but one knowledgeable editor who doesn't have all the ins and outs can do more than dozens of "expert" editors who know little but Wikipedia procedures. Thank you, again.Novangelis (talk) 13:11, 13 September 2010 (UTC)

CRF background[edit]

You tagged Conditional random field as lacking background in the intro text. Could you elaborate a bit on what you feel is missing? I might be able to improve it. Arnsholt (talk) 10:26, 5 July 2011 (UTC)

July 2012[edit]

Welcome to Wikipedia. Everyone is welcome to contribute to the encyclopedia, but when you add or change content, as you did to the article Bene Israel, please cite a reliable source for your addition. This helps maintain our policy of verifiability. See Wikipedia:Citing sources for how to cite sources, and the welcome page to learn more about contributing to this encyclopedia. Thank you.
