Skype discussion 2017-09-14[edit]

Agenda:

Observations type available from Environment Canada (per station)
1. Climate
2. Monthly
3. Daily
4. Hourly
Which weather elements do we want to include?
1. "Average Max. Temp. (°C)"
2. "Average Min. Temp. (°C)"
3. "Frequency of Precip. (%)"
4. "Highest Temp. (°C)"
5. "Highest Temp.Year"
6. "Highest Temp. Period"
7. "Highest Temp. Data Quality"
8. "Lowest Temp. (°C)"
9. "Lowest Temp. Year"
10. "Lowest Temp. Period"
11. "Lowest Temp. Data Quality"
12. "Greatest Precip. (mm)"
13. "Greatest Precip. Year"
14. "Greatest Precip. Period"
15. "Greatest Precip. Data Quality"
16. "Greatest Rainfall (mm)"
17. "Greatest Rainfall Year"
18. "Greatest Rainfall Period"
19. "Greatest Rainfall Data Quality"
20. "Greatest Snowfall (cm)"
21. "Greatest Snowfall Year"
22. "Greatest Snowfall Period"
23. "Greatest Snowfall Data Quality"
24. "Most Snow on the Ground (cm)"
25. "Most Snow on the Ground Year"
26. "Most Snow on the Ground Period"
27. "Most Snow on the Ground Data Quality"
How do we relate a station to an element?
1. Based on Lat/Lon, IATA airport code (when available)
2. Linked to closest city (if not within), airport page?
Proof of concept
1. Could we try with one station?
2. Do we have to create an element (identificator?) ?

Example: Let's take a concrete example. For the airport near the city where I was born (Bagotville Airport, code AITA YBG), the « Average max temperature » for « January 1st » is « -9,6 °C » (it is pretty cold in the winter).

WikiData elements

Bagotville Airport
Saguenay (City in which the airport is now located)

Changing weather history[edit]

Properties get created via our property proposal process and changes in the meaning of a property should at least reflect a kind of consensus. I don't see that there's any consensus for changing weather history (P4150) in a way that discourages the storage of daily/hourly weather. ChristianKl (talk) 09:21, 29 October 2017 (UTC)[reply]

@ChristianKl: Should I create a sub-property to discriminate between monthly/daily/hourly observations? This is an important information, where could it be located? Dirac (talk) 10:55, 29 October 2017 (UTC)[reply]

We haven't yet much discussions about how to deal with the tabular datatype. I consider subproperties to be a good idea and if there's a property proposal for monthly/daily/hourly we can get more input from other people as well about how they consider it to be good way to model it. ChristianKl (talk) 14:18, 29 October 2017 (UTC)[reply]

@ChristianKl:Where can we discuss about this? Dirac (talk) 14:27, 29 October 2017 (UTC)[reply]

Salut,

Juste pour te signaler une erreur dans les coordonnées de Point Lepreau (Q60882708) que je viens de corriger (classique inversion est/ouest).

Cdlt, VIGNERON (talk) 12:25, 19 March 2019 (UTC)[reply]

En effet. J'ai avisé le SMC pour qu'ils corrigent le fichier source.

Trouver les auteurs sans entrées dans Wikidata[edit]

L'idée, c'est de trouver les chaînes de caractères de author name string (P2093) les plus communes, ce qui permettra d'identifier les auteurs avec le plus d'articles rédigés, mais sans entrée dans Wikidata.

SELECT  ?item ?value

WHERE {
  ?item wdt:P31 wd:Q13442814.

Hello.

Can you merge the page "Azerbaijan at the Youth Olympics" (Q25540970) with the page "Azerbaijan at the Youth Olympics" (Q17995725)? The pages with language articles about the same topic were unknowingly created separately and have not been merged.

Thank you in advance.

Call for participation in a task-based online experiment[edit]

Dear Dirac,

I hope you are doing well,

I am Kholoud, a researcher at King's College London, and I am working on a project as part of my PhD research, in which I have developed a personalised recommender model that suggests Wikidata items for the editors based on their past edits.

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 model 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 should take no more than 15 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

Then, 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 Kholoudsaa (talk) 00:05, 14 February 2023 (UTC)[reply]

Descriptions écrasées par openrefine[edit]

Bonjour ! J'avais bien fait attention à ne pas cocher "override if present" sur openrefine, et pourtant je vois que mon import (via QuickStatements) remplace les descriptions existantes avec le "personne ayant travaillé sur la transidentité" que je ne veux absolument pas imposer sur les éléments déjà décrits. Sais-tu comment éviter ce souci ? Merci en tout cas de l'avoir remarqué, j'ai mis l'import en pause :) Exilexi (talk) 00:15, 14 October 2023 (UTC)[reply]

Aucune idée! Personnellement, je fais des requêtes SPARQ pour identifier les personnes qui n'ont pas de description, mais ce n'est peut-être pas la meilleur façon de fonctionner, ou qui s'appliquer à votre cas. Peut-être demander à la communauté? Dirac (talk) 00:19, 14 October 2023 (UTC)[reply]

Merci, je vais faire ça ! Exilexi (talk) 00:21, 14 October 2023 (UTC)[reply]

Northwest Territories weather station descriptions[edit]

Bonjour Miguel. I noticed that all the Northwest Territories weather station descriptions are misspelled as "North-Western Territory". This seems to be a systematic issue.[1][2][3][4] Can they be batch corrected? OhanaUnited^{Talk page} 17:11, 15 April 2024 (UTC)[reply]

Indeed! I'll fix that soon. Thanks for reporting, Dirac (talk) 15:20, 23 April 2024 (UTC)[reply]
