Welcome to Wikidata, FlocciNivis!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

• Introduction – An introduction to the project.
• Wikidata tours – Interactive tutorials to show you how Wikidata works.
• Community portal – The portal for community members.
• User options – including the 'Babel' extension, to set your language preferences.
• Contents – The main help page for editing and using the site.
• Project chat – Discussions about the project.
• Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, don't hesitate to ask on Project chat. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

Geklammerte Ortsangaben in Bezeichnungen

Hallo DavidJRasp,
ich wollte dich darum bitten, soweit möglich nicht geklammerte Ortsangaben in den Objektbezeichnungen zu verwenden, soweit diese nicht Teil des Namens sind. Generell kann ich bei der Thematik den Hilfsartikel zu Bezeichnungen wärmstens empfehlen.
Beste Grüße --Nw520 (talk) 22:45, 7 January 2020 (UTC)

Hallo Nw520,

Geht klar. Werd ich mich ab sofort dran halten. Ich komm so mehr oder weniger von Commons und benutze hier das Wikidata vor allem, da ich die Wikidata Infoboxen da mag. Daher hab ich meistens den Namen der Kategorien von dort übernommen. Werd ich in Zukunft dann drauf achten und auch mal meine bisherig erstellten Items dahingehend ändern. Danke dir.

Isomeric SMILES

Hey, I've noticed that you're adding isomeric SMILES to items about chemical compounds. However, I see some problems with your additions. In valproic acid (Q240642) you added canonical SMILES instead of isomeric (in that case there should be no isomeric SMILES as this compound have no stereocenters). Same in methylparaben (Q229987), danthron (Q5221244), p-aminophenol (Q2548040) and many others. What's more, in some cases isomeric SMILES was deleted earlier manually for this reason. I see also that most – if not all – additions causes constraint violations, i.e. value for isomeric SMILES does not correspond to a regular expression format specified in isomeric SMILES (P2017).

Hey, I was filling this data from PDB ligands using a script. And I didn't realize that the data there regarding the SMILES isn't consistent. I could undo the batches, in which I submitted those changes and refine my script, so that it checks if the compound has a stereocenter and that the SMILES correspond to the regex. What do you think about that? Best, DavidJRasp (talk) 21:38, 20 February 2021 (UTC)

Checking if a compound have at least one stereocenter would be great (we have a constraint that checks if there is a canonical SMILES in items having only isomeric SMILES, but there is no simple method in WD to check if an item should have an isomeric SMILES). I don't know who wrote the regexp in isomeric SMILES (P2017), but I think it usually works – if you're sure that a specific isomeric SMILES is correct and the value causes a constraint violations, report it on the property discussion page. Regards, Wostr (talk) 23:08, 20 February 2021 (UTC)

Alright, as far as I understand the regex specified for isomeric SMILES (P2017), it makes sure that at least one character is included indicating a stereocenter (\, / or @). I included this regex now into my script, which is something I should have probably done in the first place. Thank you definitely for checking my edits and making me aware of this problem.

Call for participation in a task-based online experiment

Dear DavidJRasp,

I hope you are doing good,

I am Kholoud, a researcher at King's College London, and I work on a project as part of my PhD research, in which I have developed a personalised recommender system that suggests Wikidata items for the editors based on their past edits. I am collaborating on this project with Elena Simperl and Miaojing Shi.

I am inviting you to a task-based study that will ask you to provide your judgments about the relevance of the items suggested by our system based on your previous edits.

Participation is completely voluntary, and your cooperation will enable us to evaluate the accuracy of the recommender system in suggesting relevant items to you. We will analyse the results anonymised, and they will be published to a research venue.

The study will start in late January 2022 or early February 2022, and it should take no more than 30 minutes.

If you agree to participate in this study, please either contact me at kholoud.alghamdi@kcl.ac.uk or use this form https://docs.google.com/forms/d/e/1FAIpQLSees9WzFXR0Vl3mHLkZCaByeFHRrBy51kBca53euq9nt3XWog/viewform?usp=sf_link

I will contact you with the link to start the study.

For more information about the study, please read this post: https://www.wikidata.org/wiki/User:Kholoudsaa

In case you have further questions or require more information, don't hesitate to contact me through my mentioned email.

Thank you for considering taking part in this research.

Regards

Incorrect use of instance of (P31)

Hello –

This edit to "Q105414527" (Q105414527) was in error. The properties instance of (P31) and subclass of (P279) define key ontological relationships. Because subclass of (P279) is transitive, such errors lead to numerous false inferences, such as Q105414527instance of (P31)recreation (Q184872). Before you use these properties, please look at the object item to be sure it's the one you intend. You can also review the usage instructions on these two properties, and Help:Basic membership properties. (In particular, note that all instances of a class must be of the same type.) There is often another property better suited to expressing the relationship you had in mind; you can search for one here. In this case, genre (P136) works better. Thanks!
