Change to the function model: make Z7 more uniform
by Denny Vrandečić 23 Oct '20

23 Oct '20

This is a rather technical question. If you are not interested in the inner working of the function model, feel free to safely skip this one. Currently, a function call is represented as follows (assume, Z142 is the concatenation function): Z1K1: Z7 Z7K1: Z144 Z144K1: "Wiki" Z144K2: "data" If we use global keys, it would look like this: Z1K1: Z7 Z7K1: Z144 K1: "Wiki" K2: "data" The local keys in this case get expanded against the Z7K1 value, not the Z1K1 value, as is the case for all other local keys. This makes it very different than all the other objects, and requires special handling. The suggestion is to change the representation of function calls and make them more unified compared to the other entries, i.e. like this: Z1K1: Z7 Z7K1: Z1K1: Z144 Z144K1: "Wiki" Z144K2: "data" So, instead of pulling the values into the Z7 object, we basically instantiate a function just like any other type, and wrap it into a Z7 to say that this is a function call. This needs one extra object, but it leads to much more uniform handling of objects. Any thoughts? Cheers, Denny

Newsletter #3: Naming contest first round closed, Outreachy, and more
by Denny Vrandečić 14 Oct '20

14 Oct '20

[The on-wiki version with images, links and markup is available here: https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Updates/2020-10-14] Naming contest. Today we closed the first round of the naming contest. 176 proposals were submitted, and more than 500 votes tallied over these. Two proposals are clearly leading the tally, Wikilambda and Wikifunctions. Four more proposals made it past the first round: Wikimedia Functions, Wikicode, Wikifusion, and Wikicodex. These six proposals will now undergo a first, preliminary check by the legal team of the Wikimedia Foundation, and the ones that pass the review will enter as candidates into the second and final round of the naming contest. The second round will begin October 27 and go for two weeks, until we close the voting on November 10. I am very excited to see the creativity of the community making so many proposals, and for so many people having joined the voting. Outreachy. Abstract Wikipedia also submitted a task to the Outreachy program. Outreachy is a program that was started in 2006 by the GNOME Foundation, and has grown in scope and in the number of participating organizations over the years. The goal of the program is to increase the diversity of contributors to free and open source projects by providing internship opportunities. Wikimedia joined the program in 2013 for the first time, and there have been many interns that have been mentored by the Wikimedia Foundation within the Outreachy program. For Abstract Wikipedia we have created a task that aims at analyzing the current code base in the Wikimedia projects. The wiki of functions aims to make a diverse range of functions available to the Wikimedia projects: unit conversions, calculations, formatting, and much more. Currently, the Wikimedia projects already have a mechanism to solve some of these use cases, by using modules written in Lua. The task is to take stock of the current situation. What kind of problems are being solved with the Lua modules? Which of these are available across many of our projects? Which of these are suitable for the approach that we plan for the wiki of functions, i.e. can they be resolved with purely functional solutions without access to context? Do modules have small, but important differences between their implementations in different projects? We are curious to see the results of this work, and it will directly feed into our roll-out plans to support the Wikimedia projects we plan for next year. It will hopefully help us identify which functions would be most valuable for the projects, and how to allow the projects which are interested in doing so to use them and rely on the new repository of functions. Development. Our own code base has also been developing. A new view mode is now available that considerably improves the display and readability of ZObjects in the wiki (see screenshots of before and after). The development of the programmatic evaluation of the content based on its types is ongoing, which is the last big part of our work on Phase β. External publications. Smashing Magazine published an article on “Developing for the Semantic Web”, which uses Abstract Wikipedia as its vehicle, but goes well beyond the scope of Abstract Wikipedia and discusses the meandering history of Semantic Web technologies and its current incarnations and hopes.

Weekly newsletter #2
by Denny Vrandečić 07 Oct '20

07 Oct '20

The on-wiki version is here: https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Updates/2020-10-07 Functions are a form of knowledge. Functions answer questions. A growing number of technology companies realize that and give access to functions through an increasing number of interfaces. Virtual assistants such as Apple’s Siri, Google Assistant, Amazon’s Alexa, Microsoft’s Cortana, or the open source project Mycroft all give us access to functions. You can ask Siri how many teaspoons are in two tablespoons, and it will calculate the answer for you. Web search interfaces also provide access to functions for various queries. You can ask Google about the volume of a pyramid, and you will get a beautiful user experience where you can enter the necessary values and see how the function to calculate the volume looks like. You can ask Bing about the age of Sigourney Weaver, and it won’t show you search results or find the answer on the web, but it will run a function based off of knowledge of her date of birth stored within Microsoft’s knowledge base and today’s date and show you the result. In fact, it will show you a different result if you ask this on the day this text is published and on the end of the week, as she is going to have her birthday this week. Congratulations! But the experiences these companies provide, as beautiful and useful as they are, are curated and selected by these companies. If you look for a function that goes beyond what these companies offer, you are out of luck. Let’s take one example: did you hear about the QWERTY effect <https://www.wikidata.org/wiki/Q28730063>? There was some research that claimed that since for right-handed people it is easier to type the keys on the right-hand side of their keyboard, they have a more positive sentiment towards words that have more letters typed by the keys on the right-hand side than those on the left-hand side of the keyboard. Since the majority of people are right-handed, this translates into a measurable effect where a sentiment towards a text might be influenced by the ratio of right- vs left-handed letters in the text. Now, without commenting on the merit of this research, let’s assume you are a high school graduate, writing up your application essays for the college you dream of going to. Or someone looking for a job writing a cover letter. And you hear about this effect, and, you know, it can’t hurt, why not check what the ratio of right-hand and left-hand letters in your text is before sending it off? If you are a programmer, you have the ability to write a function and run it on your text. But you know what? That’s a superpower! And if you don’t have that superpower, you’re out of luck. If the tech companies didn’t yet create that function for you to use yet, you have to go hunting for a Website or an app that offers you that function, and maybe you’ll be lucky, maybe you won’t. Most of us hold enough computing power in our hand, or around our wrist, sometimes in our fridges and light bulbs, to easily compute the answer to a question like this, and to millions of questions more. But we can’t easily run the relevant functions on the powerful computing devices we own. We want to change that. With the wiki of functions we want to democratize this superpower. We want to make functions available to many, many more people. We want to show people what they can do with the amazing computing power that they have available. And it is not just about using these functions -- this is a Wikimedia project: it is also about writing functions. It is about contributing and working together on making a large, comprehensive catalog of functions available to everyone. Maybe you know about a rare unit of measurement, or a seldomly used calendar, and want to provide a function to convert to the calendar or unit. Maybe you want to collaborate with others on functions to calculate the area that are spanned by geoshapes on Commons or Open Street Maps. Or implement a function from a scientific paper so that others can easier reuse it. We will create a platform in which a new community will collaboratively create, curate, and maintain a catalog of functions that are widely useful, where we explore a new way for everyone to share in a new form of knowledge. This is why, even if the goal of a truly multilingual Wikipedia should turn out to be even more challenging than we expect, the wiki of functions will provide a useful stepping stone and will be an interesting project in its own right. And we are working towards making it happen. Since last week, we have implemented a number of improvements to the first UX for object creation - particularly, the editing of multilingual labels is now MUCH nicer! Thanks to Arthur P. Smith for implementing that! We are currently aiming to tie in the type definitions into the object system, and to use the types for validating values and for creating generic viewers and editors. Also, the voting for the name is ongoing. You have made more than 170 proposals so far, and cast hundreds of votes. The first round of voting continues until October 13, next week Tuesday. Then the six proposals with the most votes will have a first round of legal review, and all proposals that pass that round will be taken to a second round of voting using instant-runoff. What can you do? - Vote on the name

Weekly update
by Denny Vrandečić 06 Oct '20

06 Oct '20

(A version with links is available on-wiki: https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Updates/2020-09-30 ) Hello all, Abstract Wikipedia will be a long journey, and I expect the project to shift and pivot over time. Our ultimate goal is clear: a system that allows more people to share more knowledge with more people, across languages. And we have an idea which path we are going to take. Runa Bhattacharjee, the lead of the WMF’s language team made the suggestion to keep a journal or blog of our journey, and I will try to follow the suggestion. The posts will be personal, reflective, aspirational, trying to capture unfinished thoughts. Maybe we’ll have guest posts. These might, over time, morph into more structured weekly updates. We see how it goes. I also will try to not have the posts be too long and meandering, which is particularly hard in the beginning, when there is so much still undiscussed. I constantly feel like I want to say more about everything in here, but I will try to keep these posts succinct, and will come back to many of the topics later. If there is anything you are particularly interested in, let me know! So, how have our first three months been? We are a small team, so the code base development is going on slowly. The advantage of things moving slowly is that we have the time to think through different options, and to socialize the idea of what we are doing more widely with the communities, with the many related teams, and others. I have been busy with writing documents, getting settled into a new job, and giving presentations to a wide number of stakeholders. At the same time, I was trying to read up the discussions on the mailing list and the wiki, and follow up on what the enthusiastic community is doing. We had a volunteer, ZI Jony, create Facebook pages and Telegram chats and IRC channels and more pages on-wiki, and it was all great to watch. It looks like we as a community are figuring out our communication channels, and it’s looking like a great start: in July, our mailing list has been the most active public mailing list across the whole movement. Things have cooled down since then, but community members are busily working on gathering the state of the art in natural language generation and other tasks - thanks for the volunteering effort by GrounderUK, Chris Cooley, and Adam Sobieski for their contributions. Nick has caught up on the ongoing conversations and existing documents, and will be the crucial link between the development team and the communities. He has now started and is leading the vote for the name of the wiki of functions - the first voting round started yesterday, spread the word and join the voting! So far, more than 150 proposals have been collected, displaying the amazing creativity of our community. Adam has been invaluable in helping me navigate the Foundation, and setting up meetings with people inside the Foundation. There are so many teams whose work will be paramount to the success of Abstract Wikipedia, and we are starting to have some of the meetings. Be it legal, be it comms, be it the community relation experts, be it partnerships, be it the language team, be it SRE, design, security, performance, analytics, or one of the many other teams we are working with - a project like Abstract Wikipedia obviously doesn’t happen in a vacuum, but in the context of a larger organization, which in turn is embedded in an even larger movement. And in fact, this is the only way such a project even has a shot at succeeding. Adam is also leading to find our first new hire and has posted the job description for a full-stack software engineer. We hope for more positions opening soon. Regarding our code base, James has been turning requirements and vague wishes into architecture and code. Thanks to James’s in-depth knowledge of the MediaWiki code base, he was able to set up the WikiLambda extension and build a solid foundation for further development quickly. We have defined eleven phases to take us to the launch of the wiki of functions, and so far we have finished the first one, phase α, which allows us to store objects in MediaWiki. Phase β is currently in full swing, and allows for the objects to be typed and types to be created. We are also very thankful to Arthur P. Smith, a volunteer, who has created frontend components in Vue that provide a first version of an editing interface. His first patch landed last week. Arthur is also joining our daily stand-up meetings once a week. If you want to help with development, please reach out. A screenshot of Arthur’s results is available - and also a demo system, set up by Lucas Werkmeister (in his volunteer capacity), is up and running. Lucas and Arthur, you're awesome! There are currently so many ideas floating and being discussed and so many wishes and hopes being projected onto Abstract Wikipedia, that it is almost a given that we will disappoint some of those. Apologies for that. I as well have great expectations as to where the project will lead to, and when I allow myself to dream, I imagine that this will be groundbreaking and change fundamentally not only the way Wikipedia works, but have impact well beyond that. But then I remind myself that projects like these have a terrible history of failing, and I plan to get to some of these failures in the following posts. And what we can learn from them. I am extremely grateful for the very warm welcome to the project by the communities. Now, one of the steps for us is to manage expectations. First, we are a very small, exploratory project - so don’t expect us to launch a wiki next week. Or next month. Next year? That’s our current plan. Also, even when we launch, we will launch with a very minimal project. There won’t be an integration into local Wikipedias yet. There won’t be any support for natural language generation (that is planned for 2022, if all goes well). And in fact, I am afraid, it will be even confusing, because we’re starting with a wiki for the collaborative curation of a catalog of functions, and there might well be the question, why are we doing this and not focusing on the generation of text for the local Wikipedias? And what is a function anyway and why do we need a catalog of these? I will come back to this in future posts. You can see our current best attempt at a clear and concise explanation of functions at the main project page. I want to end each post with a list of things that can be done right now, things as actionable as possible. Feel free to send suggestions my way. Things to do: * Vote in the first round of the Wiki of function naming contests (new proposals are also still allowed). The first vote ends October 13. * Work on lexicographic knowledge in Wikidata. I will come to how central this is in later posts, but this will be needed for Abstract Wikipedia to succeed and can be worked on right now. Cheers, Denny

ZObject in the extension's interface

Re: [Abstract-wikipedia] NLP issues severely overlooked (Amir E. Aharoni)
by Louis Lecailliez 24 Sep '20

24 Sep '20

Hi Amir, I understand the process is different that usual research. In fact I've seen Wikipedia grown from an unknown website to the biggest encyclopedia it is now. I use it daily in multiple languages and love it. I know what crowd sourcing could achieve. > It's also possible that the mere *finding* of these stumbling blocks by such a big, diverse, open, and active community, will itself be a contribution to the scientific knowledge around this subject. I disagree here. It would be contribution to scientic knowledge if and only if it wasn't discovered before. My email was precisely about that: capitalizing on the knowledge that has already been discovered, to avoid making the same mistake them again. It would not matter for a small project, but this one is really ambitious. We are speaking of 40 years of work by a horde of talented and very knowledgeable people, so this isn't to be dismissed easily. This thing is, my previous email was a bit abstract, because it were a review of the paper, not of the project itself. I should have made more examples to illustrate where the problem lies. Let's start with a simple example, in English, with corresponding Wikidata entities in-between parenthesis. I'm also using pseudo-turtle notation with made up relationships. France (Q142) is a country (Q6256). <Q142> <rel_is> <Q6256> . Creating the English sentence is straightforward with the naive approach presented in the paper. What is the French equivalent? La France est un pays. More information is required in the abstract representation: the text generator needs to know about the gender of both nouns (France and pays). So we need to extend the model as such: <Q142> <rel_gender> <Q1775415> . <Q6256> <rel_gender> <Q499327> . Fine! Now what about Chinese? 法國是一個國家。 What we have in the middle of the sentence is a classifier (個). The model needs the following update: <Q499327> <rel_use_classifier> <Q63153> . To handle these 3 languages, the model has already 3 additional triples just for accounting for linguistic facts occuring in these languages. Wikipedia exists in more than 300 languages, and the world has about 6000 of them, each of them having particularities that must be taken into account. Fortunately they recoup themselves in-between languages. Nonetheless the World Atlas Language Structures (https://wals.info/chapter/s1) count 144 distinct language features. Some are related to speech, but this means there is probably something like a hundred features that must be taken into account in the data model to produce valid natural language sentence. Note that in the Chinese example, there is also a number (一, one) showing up. This is a phenomenon that must be taken into account; and it's not always appearing when using 是 (to be). How complex the "lambda" system will be just to deal with this issue? Hint: very much. It also needs to be compatible with dozen of other phenomena. Then each of those features require extensive and complete data. For French, the gender of every noun entity *must* be present, otherwise there is half a chance of producing a wrong sentence each time a noun entity is encountered. For Chinese and Japanese, classifier information must be present for all noun, in case one must be enumerated. Where does the project will get the data from? (we are speaking of millions of item, most not referenced in existing dictionaries) How will this be encoded? Those are real questions that must be answered. Suppose now we have done the work for "renderers" in these three languages. They both use the more or less similar A X B structure where X is a verb meaning "to be". What would be the Japanese equivalent? The more natural structure would be like: フランスは国(だ)。 What is a play here is a topicalization (Q63105) of France, followed by a predicate (it's a country). This is very different from the previous structure, which, not surprisingly enough, needs it's own representation. To make situation more difficult, the previous (A be B) structure can also exists in Japanese, but would lead to a totally different sentence if used. The paper states that Figure 1 and 2 are examples that will be more complex in real life. Yet, the use of any existing formalism is dismissed, which mean all the situations I illustrated in this email will need to be dealt with in an ad hoc fashion. Moreover, changing formalism (be it ad hoc or not) will require to change every piece of code/data using it. This will happen everytime a language with unsupported feature(s) is added to the project. It's not hard to see how this will waste a huge amount of time and goodwill from involved people. The very code focussed tone of the paper, the english-centric approach used in the examples and the lack of references shows that the complexity of the task on the NLP front is not sufficiently conceptualized.

Besides Wiktionary, there is the "lexeme" namespace of Wikidata. It is a relatively new part of Wikidata, dealing with verbal forms. >To finish on a positive note, I would like to highlight the points I really like in the paper. First, its collaborative and open nature, like all Wikimedia projects, gives him a much higher chance of success than its predecessors. It is worth saying, for context, that there is a certain style or philosophy coming from the wiki side: more precisely, from the wikis before Wikipedia. There is the slogan "what is the simplest thing that would actually work?" You might argue, plausibly, that Wikipedia at nearly 20 years old, shows that there is a bit more to engineering than that. On the other hand, looking at Wikidata at seven years old, there is some point to the comment. It has a rather simple approach to linked structured data, compared to the Semantic Web environment. (Really, just write a very large piece of JSON and try to cope with it!) But the number of binary relations used (8K, if you count the "external links" handling) is now quite large, and has grown organically. The data modelling is in a sense primitive, sometimes non-existent. But the range of content handled really is encyclopedic. And in an area like scientific bibliography, at a scale of tens of millions of entities, the advantages of not much ontological fussiness begin to be seen. Wikidata started as an index of all Wikipedia articles, and is now five times the size needed for that: a very enriched "index". I suppose the NLP required to code up, for example, 50K chemistry articles about molecules, might be a problem that could be solved, leaving aside the general problems for the moment. In any case, there is a certain approach, neither academic nor commercial, that comes with Wikimedia and its communities, and it will be interesting to see how the issues are addressed.

I am not one of the people implementing Wikilambda, but I am just very curious about it as a member of the wider Wikimedia community. But there's a good chance that they will be useful to people who do work on the implementation. I will dare to add a little thought I have about it, however. It's possible that the challenge of building a well-functioning natural language generator is underestimated by the founders, and that they don't pay enough attention to existing work (although, knowing Denny, there is a good chance that he actually is aware of at least some of it). But there is something that the wide Wikimedia community has that I'm not sure that the past projects in this field did: The community itself. A big, worldwide, and diverse group of passionate volunteers, who love the idea of spreading free knowledge and who love their languages. Quite a lot of them also know some programming, and in the past they proved unbelievably creative and productive when writing code for Wikimedia projects as a community, in the form of templates, modules, gadgets, bots, extensions, and other tools. I'm quite sure that once the new tools become usable, this community will start doing creative things again, and it will also start reporting bugs and limitations. So yes, while it's possible that along the way both the core developers and the volunteer community will find all kinds of stumbling blocks, I'm pretty sure that they will also have all kinds of surprising success stories. It's also possible that the mere *finding* of these stumbling blocks by such a big, diverse, open, and active community, will itself be a contribution to the scientific knowledge around this subject. And don't underestimate the "open" part—that's where we really shine. This won't be a theoretical work in a lab, published in a paywalled and copyright-restricted academic journal, but fully optimized for accessibility to everyone. Yes, this whole email from me is incredibly naïve, but it's the same attitude that got us to writing the biggest and most multilingual encyclopedia in history, so maybe we can do something cool again :) -- Amir Elisha Aharoni · אָמִיר אֱלִישָׁע אַהֲרוֹנִי http://aharoni.wordpress.com ‪“We're living in pieces, I want to live in peace.” – T.

Contractions (shortened forms of words)
by Thad Guidry 31 Aug '20

31 Aug '20

Hi Team, As usual for me, I love digging and pulling out weeds from the garden beds on the weekend. :-) I searched the repo and did not see "apostrophe" or "contraction" mentioned at all. https://github.com/google/abstracttext/search?q=apostrophe&unscoped_q=apost… https://github.com/google/abstracttext/search?q=contraction&unscoped_q=cont… I was hoping to see an example conversion function to help with contractions (shortened forms of words where letters have been omitted and replaced by apostrophes and sometimes other characters) ? My use case (in the future) is to help Abstract Wikipedia to more easily handle search & matching for English idioms and deal with alternative variants that sometimes have contracted forms of words within them. For example: https://www.wikidata.org/wiki/Lexeme:L311061 "We will cross that bridge when we come to it" "We'll cross that bridge when we come to it" Idioms are so complex in English and many alternative variants with optional hyphens, apostrophes, etc. So I'm (<-- a contraction!) trying to understand some of the future ideas on how searchability might be improved by allowing hints somehow in Wikidata Lexemes and what a first practice (maybe not best practice yet!) would begin to look like. We might have parsing functions that already know that "we will" = "we'll". The lexeme for "we'll" is in fact already there https://www.wikidata.org/wiki/Lexeme:L269709 GREAT! But I think that lexeme and others are missing additional information to make them really useful with our later conversion functions or renderers? So... Some of these questions are deep, forward thinking, and probably will not have the best answers right now, but it's (<--another contraction!!) useful to ask them now I think: 1. Perhaps somehow mentioning that https://www.wikidata.org/wiki/Lexeme:L269709 is a contraction and not only a phrase? But I don't see how to do that currently. Lexical category allows only 1. If you know, let me know. 2. How would a function determine equivalency handled with Z-objects in the case of contractions? For example, would the mere fact that on L269709 that there are 2 forms -F1 and -F2, automatically return a boolean True on some function? Is that best? 3. Seeing as how ubiquitous contractions are... does that make them a good candidate in the future for separate indexing? a. Is L269709 and its -F1 and -F2 forms good enough for further building very fast lookup or conversion functions for contractions that would use ElasticSearch indexes? This could be performant enough and completely stored in memory for English language, I guess? I'm all ears (<-- an idiom!!)(means I am listening) Thad https://www.linkedin.com/in/thadguidry/

More mockups!
by Denny Vrandečić 26 Aug '20

26 Aug '20

Hello all, we have uploaded further mocks for more workflows to Meta. This includes workflows for creating new objects, view objects, edit objects, and a few mock ups for different designs, particularly on mobile. https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Early_mockups Feedback is very welcome. Stay safe, Denny

Some questions and concerns
by Trey Jones 25 Aug '20

25 Aug '20

Hi everyone, Depending on the eventual implementation details, Abstract Wikipedia may need support from the WMF Search Platform team. So a couple of us from our team had a conversation with Denny about Abstract Wikipedia, and we had some questions and concerns. Denny suggested sharing them in a more public forum, so I've posted them on the talk page on Meta: https://meta.wikimedia.org/wiki/Talk:Abstract_Wikipedia#Some_questions_and_… —Trey Trey Jones Sr. Computational Linguist, Search Platform Wikimedia Foundation UTC-4 / EDT

Phase Alpha completed
by Denny Vrandečić 24 Aug '20

24 Aug '20

Hello all, we had broken down the development work on the function wiki into a number of short phases, as can be found here: https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Phases Note that the wiki page is a bit outdated, but is used to keep a form of the backlog. The up to date view is on Phabricator here: https://phabricator.wikimedia.org/project/view/4876/ We have concluded Phase α of the development - this allows us to create ZObject on wiki and a few more things, and we have started with Phase β - creating and using on-wiki Types. (I think it is still too early for most, unless you want to dive in the code and play with that, to go and try out the wiki. We expect that the first time this would become interesting for some would be when we conclude Phase ε, after which new functions can be composed.) Stay safe, Denny
