WikiCite issue

GLAM ♥ data — what is a gallery, library, archive or museum without a catalogue? It follows that Wikidata must love librarians. Bibliography supports students and researchers in any topic, but open and machine-readable bibliographic data even more so, outside the silo. Cue the WikiCite initiative, which was meeting in conference this week, in the Bay Area of California.

Wikidata training for librarians at WikiCite 2018

In fact there is a broad scope: "Open Knowledge Maps via SPARQL" and the "Sum of All Welsh Literature", identification of research outputs, Library.Link Network and Bibframe 2.0, OSCAR and LUCINDA (who they?), OCLC and Scholia, all these co-exist on the agenda. Certainly more library science is coming Wikidata's way. That poses the question about the other direction: is more Wikimedia technology advancing on libraries? Good point.

Wikimedians generally are not aware of the tech background that can be assumed, unless they are close to current training for librarians. A baseline definition is useful here: "bash, git and OpenRefine". Compare and contrast with pywikibot, GitHub and mix'n'match. Translation: scripting for automation, version control, data set matching and wrangling in the large, are on the agenda also for contemporary library work. Certainly there is some possible common ground here. Time to understand rather more about the motivations that operate in the library sector.

NPR Newsletter No.16 15 December 2018Edit

Hello Diptanshu Das,

Reviewer of the Year
New page reviewer of the year cup.svg

This year's award for the Reviewer of the Year goes to Onel5969. Around on Wikipedia since 2011, their staggering number of 26,554 reviews over the past twelve months makes them, together with an additional total of 275,285 edits, one of Wikipedia's most prolific users.

Thanks are also extended for their work to JTtheOG (15,059 reviews), Boleyn (12,760 reviews), Cwmhiraeth (9,001 reviews), Semmendinger (8,440 reviews), PRehse (8,092 reviews), Arthistorian1977 (5,306 reviews), Abishe (4,153 reviews), Barkeep49 (4,016 reviews), and Elmidae (3,615 reviews).
Cwmhiraeth, Semmendinger, Barkeep49, and Elmidae have been New Page Reviewers for less than a year — Barkeep49 for only seven months, while Boleyn, with an edit count of 250,000 since she joined Wikipedia in 2008, has been a bastion of New Page Patrol for many years.

See also the list of top 100 reviewers.

Less good news, and an appeal for some help

The backlog is now approaching 5,000, and still rising. There are around 640 holders of the NPR flag, most of whom appear to be inactive. The 10% of the reviewers who do 90% of the work could do with some support especially as some of them are now taking a well deserved break.


Really good news - NPR wins the Community Wishlist Survey 2019

At #1 position, the Community Wishlist poll closed on 3 December with a resounding success for NPP, reminding the WMF and the volunteer communities just how critical NPP is to maintaining a clean encyclopedia and the need for improved tools to do it. A big 'thank you' to everyone who supported the NPP proposals. See the results.


Training video

Due to a number of changes having been made to the feed since this three-minute video was created, we have been asked by the WMF for feedback on the video with a view to getting it brought up to date to reflect the new features of the system.

Learning from Zotero

Zotero is free software for reference management by the Center for History and New Media: see Wikipedia:Citing sources with Zotero. It is also an active user community, and has broad-based language support.

Zotero logo

Besides the handiness of Zotero's warehousing of personal citation collections, the Zotero translator underlies the citoid service, at work behind the VisualEditor. Metadata from Wikidata can be imported into Zotero; and in the other direction the zotkat tool from the University of Mannheim allows Zotero bibliographies to be exported to Wikidata, by item creation. With an extra feature to add statements, that route could lead to much development of the focus list (P5008) tagging on Wikidata, by WikiProjects.

Zotero demo video

There is also a large-scale encyclopedic dimension here. The construction of Zotero translators is one facet of Web scraping that has a strong community and open source basis. In that it resembles the less formal mix'n'match import community, and growing networks around other approaches that can integrate datasets into Wikidata, such as the use of OpenRefine.

Looking ahead, the thirtieth birthday of the World Wide Web falls in 2019, and yet the ambition to make webpages routinely readable by machines can still seem an ever-retreating mirage. Wikidata should not only be helping Wikimedia integrate its projects, an ongoing process represented by Structured Data on Commons and lexemes. It should also be acting as a catalyst to bring scraping in from the cold, with institutional strengths as well as resourceful code.

Everything flows (and certainly data does)

Recently Jimmy Wales has made the point that computer home assistants take much of their data from Wikipedia, one way or another. So as well as getting Spotify to play Frosty the Snowman for you, they may be able to answer the question "is the Pope Catholic?" Possibly by asking for disambiguation (Coptic?).

Amazon Echo device using the Amazon Alexa service in voice search showdown with the Google rival on an Android phone

Headlines about data breaches are now familiar, but the unannounced circulation of information raises other issues. One of those is Gresham's law stated as "bad data drives out good". Wikipedia and now Wikidata have been criticised on related grounds: what if their content, unattributed, is taken to have a higher standing than Wikimedians themselves would grant it? See Wikiquote on a misattribution to Bismarck for the usual quip about "law and sausages", and why one shouldn't watch them in the making.

Wikipedia has now turned 18, so should act like as adult, as well as being treated like one. The Web itself turns 30 some time between March and November this year, per Tim Berners-Lee. If the Knowledge Graph by Google exemplifies Heraclitean Web technology gaining authority, contra GIGO, Wikimedians still have a role in its critique. But not just with the teenage skill of detecting phoniness.

There is more to beating Gresham than exposing the factoid and urban myth, where WP:V does do a great job. Placeholders must be detected, and working with Wikidata is a good way to understand how having one statement as data can blind us to replacing it by a more accurate one. An example that is important to open access is that, firstly, the term itself needs considerable unpacking, because just being able to read material online is a poor relation of "open"; and secondly, trying to get Creative Commons license information into Wikidata shows up issues with classes of license (such as CC-BY) standing for the actual license in major repositories. Detailed investigation shows that "everything flows" exacerbates the issue. But Wikidata can solve it.

What is a systematic review?

Systematic reviews are basic building blocks of evidence-based medicine, surveys of existing literature devoted typically to a definite question that aim to bring out scientific conclusions. They are principled in a way Wikipedians can appreciate, taking a critical view of their sources.

PRISMA flow diagram for a systematic review

Ben Goldacre in 2014 wrote (link below) "[...] : the "information architecture" of evidence based medicine (if you can tolerate such a phrase) is a chaotic, ad hoc, poorly connected ecosystem of legacy projects. In some respects the whole show is still run on paper, like it's the 19th century." Is there a Wikidatan in the house? Wouldn't some machine-readable content that is structured data help?

2011 photograph by Bernard Schittny of the "Legacy Projects" group

Most likely it would, but the arcana of systematic reviews and how they add value would still need formal handling. The PRISMA standard dates from 2009, with an update started in 2018. The concerns there include the corpus of papers used: how selected and filtered? Now that Wikidata has a 20.9 million item bibliography, one can at least pose questions. Each systematic review is a tagging opportunity for a bibliography. Could that tagging be reproduced by a query, in principle? Can it even be second-guessed by a query (i.e. simulated by a protocol which translates into SPARQL)? Homing in on the arcana, do the inclusion and filtering criteria translate into metadata? At some level they must, but are these metadata explicitly expressed in the articles themselves? The answer to that is surely "no" at this point, but can TDM find them? Again "no", right now. Automatic identification doesn't just happen.

Actually these questions lack originality. It should be noted though that WP:MEDRS, the reliable sources guideline used here for health information, hinges on the assumption that the usefully systematic reviews of biomedical literature can be recognised. Its nutshell summary, normally the part of a guideline with the highest density of common sense, allows literature reviews in general validity, but WP:MEDASSESS qualifies that indication heavily. Process wonkery about systematic reviews definitely has merit.

Hello Diptanshu Das,

News
Discussions of interest
  • Two elements of CSD G6 have been split into their own criteria: R4 for redirects in the "File:" namespace with the same name as a file or redirect at Wikimedia Commons (Discussion), and G14 for disambiguation pages which disambiguate zero pages, or have "(disambiguation)" in the title but disambiguate a single page (Discussion).
  • {{db-blankdraft}} was merged into G13 (Discussion)
  • A discussion recently closed with no consensus on whether to create a subject-specific notability guideline for theatrical plays.
  • There is an ongoing discussion on a proposal to create subject-specific notability guidelines for chemicals and organism taxa.
Reminders
  • NPR is not a binary keep / delete process. In many cases a redirect may be appropriate. The deletion policy and its associated guideline clearly emphasise that not all unsuitable articles must be deleted. Redirects are not contentious. See a classic example of the templates to use. More templates are listed at the R template index. Reviewers who are not aware, do please take this into consideration before PROD, CSD, and especially AfD because not even all admins are aware of such policies, and many NAC do not have a full knowledge of them.
NPP Tools Report
  • Superlinks – allows you to check an article's history, logs, talk page, NPP flowchart (on unpatrolled pages) and more without navigating away from the article itself.
  • copyvio-check – automatically checks the copyvio percentage of new pages in the background and displays this info with a link to the report in the 'info' panel of the Page curation toolbar.
  • The NPP flowchart now has clickable hyperlinks.

When in the cloud, do as the APIs do

Half a century ago, it was the era of the mainframe computer, with its air-conditioned room, twitching tape-drives, and appearance in the title of a spy novel Billion-Dollar Brain then made into a Hollywood film. Now we have the cloud, with server farms and the client–server model as quotidian: this text is being typed on a Chromebook.

Logo of Cloud API on Google Cloud Platform

The term Applications Programming Interface or API is 50 years old, and refers to a type of software library as well as the interface to its use. While a compiler is what you need to get high-level code executed by a mainframe, an API out in the cloud somewhere offers a chance to perform operations on a remote server. For example, the multifarious bots active on Wikipedia have owners who exploit the MediaWiki API.

APIs (called RESTful) that allow for the GET HTTP request are fundamental for what could colloquially be called "moving data around the Web"; from which Wikidata benefits 24/7. So the fact that the Wikidata SPARQL endpoint at query.wikidata.org has a RESTful API means that, in lay terms, Wikidata content can be GOT from it. The programming involved, besides the SPARQL language, could be in Python, younger by a few months than the Web.

Magic words, such as occur in fantasy stories, are wishful (rather than RESTful) solutions to gaining access. You may need to be a linguist to enter Ali Baba's cave or the western door of Moria (French in the case of "Open Sesame", in fact, and Sindarin being the respective languages). Talking to an API requires a bigger toolkit, which first means you have to recognise the tools in terms of what they can do. On the way to the wikt:impactful or polymathic modern handling of facts, one must perhaps take only tactful notice of tech's endemic problem with documentation, and absorb the insightful point that the code in APIs does articulate the customary procedures now in place on the cloud for getting information. As Owl explained to Winnie-the-Pooh, it tells you The Thing to Do.

Completely clouded?
Cloud computing logo

Talk of cloud computing draws a veil over hardware, but also, less obviously but more importantly, obscures such intellectual distinction as matters most in its use. Wikidata begins to allow tasks to be undertaken that were out of easy reach. The facility should not be taken as the real point.

Coming in from another angle, the "executive decision" is more glamorous; but the "administrative decision" should be admired for its command of facts. Think of the attitudes ad fontes, so prevalent here on Wikipedia as "can you give me a source for that?", and being prepared to deal with complicated analyses into specified subcases. Impatience expressed as a disdain for such pedantry is quite understandable, but neither dirty data nor false dichotomies are at all good to have around.

Issue 13 and Issue 21, respectively on WP:MEDRS and systematic reviews, talk about biomedical literature and computing tasks that would be of higher quality if they could be made more "administrative". For example, it is desirable that the decisions involved be consistent, explicable, and reproducible by non-experts from specified inputs.

What gets clouded out is not impossibly hard to understand. You do need to put together the insights of functional programming, which is a doctrinaire and purist but clearcut approach, with the practicality of office software. Loopless computation can be conceived of as a seamless forward march of spreadsheet columns, each determined by the content of previous ones. Very well: to do a backward audit, when now we are talking about Wikidata, we rely on integrity of data and its scrupulous sourcing: and clearcut case analyses. The MEDRS example forces attention on purge attempts such as Beall's list.

Semantic Web and TDM – a ContentMine view

Two dozen issues, and this may be the last, a valediction at least for a while.

It's time for a two-year summation of ContentMine projects involving TDM (text and data mining).

Wikidata and now Structured Data on Commons represent the overlap of Wikimedia with the Semantic Web. This common ground is helping to convert an engineering concept into a movement. TDM generally has little enough connection with the Semantic Web, being instead in the orbit of machine learning which is no respecter of the semantic. Don't break a taboo by asking bots "and what do you mean by that?"

The ScienceSource project innovates in TDM, by storing its text mining results in a Wikibase site. It strives for compliance of its fact mining, on drug treatments of diseases, with an automated form of the relevant Wikipedia referencing guideline MEDRS. Where WikiFactMine set up an API for reuse of its results, ScienceSource has a SPARQL query service, with look-and-feel exactly that of Wikidata's at query.wikidata.org. It also now has a custom front end, and its content can be federated, in other words used in data mashups: it is one of over 50 sites that can federate with Wikidata.

The human factor comes to bear through the front end, which combines a link to the HTML version of a paper, text mining results organised in drug and disease columns, and a SPARQL display of nearby drug and disease terms. Much software to develop and explain, so little time! Rather than telling the tale, Facto Post brings you ScienceSource links, starting from the how-to video, lower right.

Hello Diptanshu Das,

WMF at work on NPP Improvements

Niharika Kohli, a product manager for the growth team, announced that work is underway in implementing improvements to New Page Patrol as part of the 2019 Community Wishlist and suggests all who are interested watch the project page on meta. Two requested improvements have already been completed. These are:

  • Allow filtering by no citations in page curation
  • Not having CSD and PRODs automatically marked as reviewed, reflecting current consensus among reviewers and current Twinkle functionality.
Reliable Sources for NPP

Rosguill has been compiling a list of reliable sources across countries and industries that can be used by new page patrollers to help judge whether an article topic is notable or not. At this point further discussion is needed about if and how this list should be used. Please consider joining the discussion about how this potentially valuable resource should be developed and used.

Backlog drive coming soon

Look for information on the an upcoming backlog drive in our next newsletter. If you'd like to help plan this drive, join in the discussion on the New Page Patrol talk page.
