Semantic MediaWiki/SMWCon2023

From Freephile Wiki

The 3-day program was fantastic!

One major announcement is that through Open Collective individuals and organizations can donate money to the Semantic MediaWiki project.

Day One[edit | edit source]

Day Two[edit | edit source]

Canasta[edit | edit source]

Canasta is a production grade distribution of MediaWiki developed by an informal consortium of the leading wiki hosters: WikiWorks, WikiTeq and MyWikis. It is also used / developed by the United States Space Force (USSF)

Digital Accessibility[edit | edit source]

Accessibility is extremely important, so do it everywhere all the time.

From the conference, here's the 5 minute call to action

Major changes on interfaces of MediaWiki RDBMS library[edit | edit source]

https://www.mediawiki.org/wiki/Manual:Database_access

This interesting example of Python3 code[1] uses antlr, php lexer and php parser to clean up deprecated Database::select() calls in PHP codebases

Day Three[edit | edit source]

Open Semantic Lab[edit | edit source]

Open Semantic Lab starts with the premise that Ontologies[2] are key to standardize everything... but tools are needed to make ontologies applicable in everyday research. The OSL is the holistic and community driven platform to fulfill this roll... and links people (knowledge), machines (data) and algorithms (AI) equally.

Since last year, the project has been completely based on the industry standards of JSON-SCHEMA and JSON-LD, enabling new applications quickly with easy integration to any third party software. Experimental support has been added to achieve Python triggered workflows through REST APIs and LocalGPT Q&A + search assistance.

The whole subject is quite advanced, so it can be hard to wrap your head around it. A good way to understand the power of the Open Semantic Lab system is to look at an example use case where it was put into practice[3]. At https://kiprobatt.de/wiki, they illustrate Intelligent battery cell manufacturing. The diagramming capabilities of the system are impressive - showing interactive (clickable) node graphs plus Draw.io integration. The underlying software application is not for the faint-of-heart. Checking the Special:Version page shows an extensive list of complex MediaWiki and Semantic MediaWiki extensions. The latest version's technology stack is represented here.

See also: https://opensemantic.world/ - a reference deployment of the OpenSemanticWorld packages. Here is a brief explanation of the key differences from 'vanilla' Semantic MediaWiki[4]. You can see at Special:Version, the extensions and software components.

Task tracking[edit | edit source]

HalloWelt! combines four extensions they created to make useful task tracking in (Semantic) MediaWiki

Miriam Schlindwein presented how it's possible to create tasks, assign them to someone, add due dates and how they can be controlled

Realtime integrations with GitLab[edit | edit source]

Natural Language Queries to Wikidata: A Naïve Prototype[edit | edit source]

Application architecture
architecture

Robert Timms - Sr. Software Engineer Wikibase Suite, Wikimedia Deutschland gave a talk (code slides try it) about querying Wikibase with an LLM. Slides 9-22 go from the application architecture to the 'tada' moment.


Not the goal of the talk, but he revealed some of the key drawbacks of using "AI" in the first place:

  1. Outdated information
  2. Prone to hallucinations
  3. No sources (AI doesn't tell you how or why it claims to be authoritative.)

This is supposed to be addressed in part by using the RAG technique.

Fixing Wikidata[edit | edit source]

Yaron Koren gave a great presentation (slides) called Enhanced Wikibase on how Wikibase (and therefore Wikidata) are missing features. He showed how he implemented these missing features in a series of developments. One is showcased at Wikidata Walkabout - a drill-down and query interface to Wikibase sites; powered by Anvesha - a JavaScript library. Video presentation

Codex, the Design System for Wikimedia[edit | edit source]

The Wikimedia Codex design system is analogous to Google's Material Design, Shopify's Polaris, or IBM's Carbon

Codex leverages Vue.js See mw:Codex for details about using the system and it's relationship to prior efforts like MediaWiki UI (deprecated) or OOUI
