Oggetto: Using wikidata to extract aditional information about entities
Data: Thu, 16 Dec 2021 10:33:49 +0000
Mittente: Ricardo Pinto
My name is Ricardo Pinto, I am currently doing my thesis, and I am trying
to make calls to Wikidata. I am presently using SPARQLWrapper in python to
make the calls, but I am having trouble with some things that I hope you
can help me with.
1. How can I get the entity identifier? Given an entity (e.g. Portugal) I
need to get its identifier (e.g., Q45). Currently, I am doing this
by searching on google, but I need this to be systematic. Can you help me?
2. While searching for entities related to another entity, I need to make
calls using properties. Is there a way to know what the most used
properties are? I need a systematic way to choose properties to search. Can
you help me?

We’ve been collecting lexicographical data for quite a while now. The first
applications are being built on top of it as well. One big remaining wish
is to make it possible to access the data in Lexemes also from Wiktionary.
We’re enabling it on the first Wiktionaries now.
On December 15th, we’ll enable the *initial version of Lua access to
lexicographical data* on the following wikis:
- Bengali Wiktionary https://bn.wiktionary.org/
- Basque Wiktionary https://eu.wiktionary.org
- Wikidata https://www.wikidata.org/
- Test Wikidata https://test.wikidata.org/
The Lua interface (i.e. the available functions and methods) is documented
<https://www.mediawiki.org/wiki/Extension:WikibaseLexeme/Lua> (you can see
a live example, with links to the relevant template and module, at Beta
English Wiktionary: cat <https://en.wiktionary.beta.wmflabs.org/wiki/cat>).
If you have suggestions for improving it (e.g. extra functions that would
be useful), feel free to add them to phab:T294637
Please note that *the Lua interface is not stable yet*; breaking changes
may be made at any time, though usually not without some note on
Phabricator first. We recommend not fully relying on this yet. If your wiki
would nevertheless like to have Lua access while it is not stable yet, feel
free to leave a note at phab:T294159
<https://phabricator.wikimedia.org/T294159>. Otherwise, we hope to
stabilize the interface soon, at which point we’ll start enabling this
feature on more Wiktionaries. If you're active on another Wiktionary and
would like to see the feature enabled, feel free to reach out to us after
talking to your community, and we will make sure to include it in the list
for future deployments..
Change dispatching, i.e. the automatic updating of local wiki pages when
relevant changes on Wikidata are made, as well as integration with recent
changes and the watchlist, ought to work; however, usage tracking (i.e.
determining which changes on Wikidata affect the local wiki) is not very
fine-grained yet: if a local page uses any data from a Lexeme, then any
change to the Lexeme on Wikidata will cause the page to be rerendered and
that change will be added to the recent changes on the wiki, even if the
change is unrelated to the data which the page actually uses. We will
improve this at a later point; in the meantime, wikis that heavily use
lexicographical data may see “too many” Wikidata entries in their recent
changes and watchlists.
We are really happy to beta-test Lua access to Lexemes with you, and we are
looking forward to your *feedback and bug reports* (they can be tracked
under phab:T294159 <https://phabricator.wikimedia.org/T294159> or on the Report
a Technical Problem page <https://www.wikidata.org/wiki/Wikidata:RATP>). We
would love to know *how you are using Lexemes on Wiktionary*, so when you
are running your first experiments, feel free to let us know!

As many of you know, there is a risk of Blazegraph, Wikidata Query
Service’s backend, catastrophically failing before we are able to properly
scale the service.
Thus, it is important for us to have a playbook for what actions we will
take in the event of such a disaster, as well as making that playbook
This Blazegraph failure playbook
is now available, and we welcome you to take a look at it, though we hope
to never use it.

# **30th ACM Conference on User Modeling, Adaptation and Personalization
Barcelona*, Spain, July 4–7, 2022
(*) Due to the ongoing COVID-19 pandemic, we are planning for a hybrid
conference and will accommodate online presentations where needed.
- Abstracts due: February 10, 2022 (mandatory)
- Full paper due: February 17, 2022
**BACKGROUND AND SCOPE**
**ACM UMAP** – ***User Modeling, Adaptation and Personalization*** – is
the premier international conference for researchers and practitioners
working on systems that adapt to individual users or to groups of users,
and that collect, represent, and model user information. **ACM UMAP** is
sponsored by ACM SIGCHI (https://sigchi.org) and SIGWEB
(https://www.sigweb.org), and organized with User Modeling Inc.
(https://um.org) as the core Steering Committee, extended with past
years’ chairs. The proceedings are published by the **ACM** and will be
part of the ACM Digital Library (https://dl.acm.org).
**ACM UMAP** covers a wide variety of research areas where
personalization and adaptation may be applied. The main theme of **UMAP
2022** is ***“User control in personalized systems”***. Specifically, we
welcome submissions related to user modeling, personalization, and
adaptation in all areas of personalized systems, with an emphasis on how
to balance adaptivity and user control. Below we present a short (but
not prescriptive) list of topics of importance to the conference.
ACM UMAP is co-located and collaborates with the ACM Hypertext
conference (https://ht.acm.org/ht2022/). UMAP takes place one week after
Hypertext, and uses the same submission dates and formats. We expect
authors to submit research on personalized systems to UMAP and invite
authors to submit their Web-related work without a focus on
personalization to the Hypertext conference. The two conferences will
organize one shared track on **personalized recommender systems** (same
track chairs and PC, see the track description).
- Paper Abstracts: February 10, 2022 (mandatory)
- Full paper: February 17, 2022
- Notification: April 11, 2022
- Conference: July 4-July 7, 2022
**Note**: The submissions deadlines are at 11:59pm AoE time (Anywhere on
We welcome submissions related to *user modeling, personalization, and
adaptation in any area*. The topics listed below are not intended to
limit possible contributions. **Detailed descriptions and the suggested
topics for each track are reported in the online version of the CFP on
the UMAP 2022 web site.**
### **Personalized Recommender Systems***
**Track Chairs: Osnat Mokryn (University of Haifa), Eva Zangerle
(University of Innsbruck, Austria) and Markus Zanker (University of
Bolzano, Italy, and University of Klagenfurt, Austria)**
(*) This is a joint track between ACM UMAP and ACM Hypertext (same track
chairs, overlapping PC). Authors planning to contribute to this track
can submit to either conference, depending on their broader interest in
either Hypertext or UMAP. Track chairs organize a special issue in the
journal New Review of Hypermedia and Multimedia.
This track aims to provide a forum for researchers and practitioners to
discuss open challenges, latest solutions and novel research approaches
in the field of recommender systems. In addition to mature research
works addressing technical aspects pertaining to recommendations, we
also particularly welcome research contributions that address questions
related to the user perception and the business value of recommender
### **Adaptive Hypermedia, Semantic, and Social Web**
**Track Chairs: Alexandra I. Cristea (Durham University, UK) and Peter
Brusilovsky (University of Pittsburgh, US)**
This track aims to provide a forum to researchers to discuss open
research problems, solid solutions, latest challenges, novel
applications, and innovative research approaches in adaptive hypermedia,
semantic and social web. We invite original submissions addressing all
aspects of personalization, user models building, and personal
experience in online social systems.
### **Intelligent User Interfaces**
**Track chairs: Elisabeth Lex (Graz University of Technology, Austria)
and Marko Tkalcic (University of Primorska, Slovenia)**
This topic can be characterized by exploring how to make the interaction
between computers and people smarter and more productive, which may
leverage solutions from human-computer interaction, data mining, natural
language processing, information visualization, and knowledge
representation and reasoning.
### **Technology-Enhanced Adaptive Learning**
**Track chairs: Judy Kay (University of Sydney, Australia) and Sharon
Hsiao (Santa Clara University, US)**
This track invites researchers, developers, and practitioners from
various disciplines to present their innovative learning solutions,
share acquired experience, and discuss their modeling challenges for
personalized adaptive learning.
### **Fairness, Transparency, Accountability, and Privacy**
**Track chairs: Bamshad Mobasher (DePaul University College of Computing
and Digital Media, US) and Munindar P. Singh (NC State University, US)**
Adaptive systems researchers and developers have a social responsibility
to care about the impact of their technologies on individual people
(users, providers, and other stakeholders) and on society. This track
invites work that pertains to the science of building, maintaining,
evaluating, and studying adaptive systems that are fair, transparent,
respectful of users’ privacy, and beneficial to society.
### **Personalization for Persuasive and Behavior Change Systems**
**Track chairs: Julita Vassileva (University of Saskatchewan, Canada)
and Panagiotis Germanakos (SAP SE, Germany)**
This track invites original submissions addressing the areas of
personalization and tailoring for persuasive technologies, including but
not limited to personalization models, user models, computational
personalization, design and evaluation methods, and personal experience
designing personalized and adaptive behaviour change technologies.
### **Virtual Assistants and Personalized Human-robot Interaction**
**Track chairs: Radhika Garg (Syracuse University, US) and Cristina Gena
(University of Torino, Italy)**
This track aims at investigating new models and techniques for the
adaptation of synthetic companions (e.g., virtual assistants, chatbots,
social robots) to the individual user.
### **Research Methods and Reproducibility**
**Track chairs: Odd Erik Gundersen (Norwegian University of Science and
Technology, Norway) and Dietmar Jannach (University of Klagenfurt,
This track accepts works on methodologies for the evaluation of
personalized systems, benchmarks, measurement scales, with particular
attention to reproducibility of results and of techniques.
**SUBMISSION AND REVIEW PROCESS**
Please consult the conference website for the submission link:
The maximum length is **14 pages (excluding references) in the ACM new
single-column format**. We encourage papers of any length up to 14
pages; reviewers will be asked to comment on whether the length is
appropriate for the contribution.
**Additional review criteria are available in the online version of the
CFP on the UMAP 2022 web site.**
Each accepted paper will be included in the conference proceedings and
presented at the conference.
UMAP uses a **double blind** review process. Authors must omit their
names and affiliations from submissions, and avoid obvious identifying

after the very successful panel on "20 years into ISWC: What's next beyond
Knowledge Graphs?", the Distributed Knowledge Graphs (DKG) COST Action
[1,2] organizes a talk series in collaboration with SWSA  on aspects
related to the Semantic Web research. On *Tuesday 7th December at 18.00 CET**
Ora Lassila will give a talk "On the broad applicability of Semantic Web
technologies". I include the talk's abstract here but you can also find
more information as well as the link to the online stream before the talk
starts at https://cost-dkg.eu/talks.
Ora Lassila: "On the broad applicability of Semantic Web technologies"
About the talk: The Semantic Web, despite how it was originally advertised,
was not a replacement for the World Wide Web, nor was it really knowledge
representation (KR) solely for the Web. Rather, the Semantic Web is KR
using Web technologies. The different technologies and standards of the
Semantic Web have broad applicability in many areas distinctly outside of
what we consider to be the “Web”. The DAML-S (later OWL-S) effort was one
such example: apply ontologies to the problem of describing the semantics
of functionality and services (in this case Web services, but the concept
was more general). While the effort may not have been successful in the
long term, it was an early example of the application of Semantic Web
technologies and approaches to a wide variety of use cases and domains.
These include agent-based computing, ubiquitous computing,
context-awareness, policies, privacy, enterprise knowledge graphs, and many
others. But there is still an even bigger role for Semantic Web
technologies: Modern enterprise data practice is messy, with daunting
problems such as data integration, elimination of “data silos”, and
alignment of semantics. This “messiness” will be perpetuated until we have
a practical unifying logical representation for data and semantics, and the
promise of Semantic Web is that it could be this representation.
