Dear all,
We are proud to announce that we will organize the masterclass “DBpedia
Knowledge Graph Tutorial for Beginners” at the Connected Data World
event. The masterclass will take place online on December 2, 2021 at
4:15pm CET and it targets existing and potential new users of DBpedia,
developers that wish to learn basics about the DBpedia Knowledge Graph
and learn how to replicate and deploy DBpedia on a local infrastructure
as well as Linked Data and Knowledge Graph adopters.
# Highlights
In this masterclass, participants will learn how to consume the DBpedia
Knowledge Graph (KG) with the least amount of effort. The masterclass
will introduce the DBpedia KG and explain its dataset partitions.
Particular focus will be put on “usability”. On a selected use case, we
will explain the process of working with DBpedia KG and DBpedia
technology stack (DBpedia Databus, DBpedia Spotlight, DBpedia Docker)
and illustrate the potential and the benefits of using DBpedia.

What is the “DBpedia Snapshot” Release?
Historically, this release has been associated with many names: "DBpedia
Core", "EN DBpedia", and — most confusingly — just "DBpedia". In fact,
it is a combination of —
*
EN Wikipedia data— A small, but very useful, subset (~ 1 Billion
triples or 14%) of the whole DBpedia extraction
<https://link.springer.com/chapter/10.1007/978-3-030-59833-4_1>using
theDBpedia Information Extraction Framework
<https://github.com/dbpedia/extraction-framework>(DIEF), comprising
structured information extracted from the English Wikipedia plus
some enrichments from other Wikipedia language editions, notably
multilingual abstracts in ar, ca, cs, de, el, eo, es, eu, fr, ga,
id, it, ja, ko, nl, pl, pt, sv, uk, ru, zh.
*
Links— 62 million community-contributed cross-references and
owl:sameAs links to other linked data sets on the Linked Open Data
(LOD) Cloud that allow to effectively find and retrieve further
information from the largest, decentral, change-sensitive knowledge
graph on earth that has formed around DBpedia since 2007.
*
Community extensions— Community-contributed extensions such as
additional ontologies and taxonomies.
Release Frequency & Schedule
Going forward, releases will be scheduled for the 15th of February, May,
July, and October (with +/- 5 days tolerance), and are named using the
same date convention as the Wikipedia Dumps that served as the basis for
the release. An example of the release timeline is shown below:
September 6–8
Sep 8–20

The Journal of Web Semantics (JWS) invites submissions for a special
issue on Community-based Knowledge Bases and Knowledge Graphs, edited by
Tim Finin, Sebastian Hellmann, David Martin, and Elena Simperl. (contact
email: cbkb(a)cs.umbc.edu <mailto:cbkb@cs.umbc.edu>) Submissions are due
by November 01, 2021. Please see the JWS post here:
http://www.websemanticsjournal.org/2021/06/cfp-community-based-knowledge-ba…
<http://www.websemanticsjournal.org/2021/06/cfp-community-based-knowledge-ba…>
Introduction
Community-based knowledge bases (KBs) and knowledge graphs (KGs) are
critical to many domains. They contain large amounts of information,
used in applications as diverse as search, question-answering systems,
and conversational agents. They are the backbone of linked open data,
helping connect entities from different datasets. Finally, they create
rich knowledge engineering ecosystems, making significant, empirical
contributions to our understanding of KB/KG science, engineering, and
practices. From here forward, we use "KB" to include both knowledge
bases and knowledge graphs. Also, "KB" and "knowledge" encompass both
ontology/schema and data.
Community-based KBs come in many shapes and sizes, but they tend to
share a number of commonalities:
*
They are created through the efforts of a group of contributors,
following a set of agreed goals, policies, practices, and quality norms.
*
They are available under open licenses.
*
They are central to knowledge-sharing networks bringing together
various stakeholders.
*
They serve the needs of a community of users, including, but not
restricted to, their contributor base.
*
Many draw their content from crowdsourced resources (such as
Wikipedia, OpenStreetMap).
Examples of community-based KBs include Wikidata, DBpedia, ConceptNet,
GeoNames, FrameNet, and Yago. This special issue will highlight recent
research, challenges, and opportunities in the field of community-based
KBs and the interaction and processes between stakeholders and the KBs.
We welcome papers on a wide variety of topics. Papers that focus on the
participation of a community of contributors are especially encouraged.
Topics of interest
We are looking for studies, frameworks, methods, techniques and tools on
topics such as the following:
*
The impact of community involvement on characteristics of KBs such
as requirements, design, technology choices, policies, etc. For
example, how are KB characteristics driven by the community and
reflective of the community's needs?
*
Conversely, the impact of KB characteristics on community
involvement. For example, how do changes in these characteristics
affect the participation and behavior of members of the community?
*
Organizational challenges and solutions in developing and managing
community-based KBs.
*
Technical challenges and solutions in community-based KBs,
concerning a technical area such as:
o
Representation of knowledge and logical foundations
o
Reasoning, querying, and constraint-checking
o
Knowledge acquisition
o
Knowledge preparation (e.g., cleaning, deduplication, alignment,
merging)
o
Maintaining consistency with external sources
o
Representing and managing metadata (including issues involved in
adding metadata to relation instances)
o
Provenance
o
Quality assurance
*
User interfaces and experience, both for contributing to the KB and
using it, by different user groups.
*
Implemented metrics and quality tests to guide the community in
improving KG quality and expanding KG coverage.
*
Achieving and managing knowledge diversity, for instance, in the
form of multilinguality, multi-cultural coverage, multiple points of
view, and a diverse and inclusive contributor base.
*
Detecting and avoiding malicious, inappropriate, and misleading
content in community-based KBs.
*
Biases in community-based KBs and their impact on downstream uses of
KB content.
*
Community-based KBs in science, medicine, law, government, or other
domains.
*
Handling specialized types of knowledge (such as commonsense,
probabilistic, or linguistic knowledge) in a community setting.
*
Methods and tools to manage KB evolution, including change
detection, change management, conflict resolution, visualization of
change history.
*
Tools and affordances supporting community or collaborative
activities, including discussions, feedback, decision making, task
allocation, etc.
*
Motivations and incentives affecting community participation.
*
Approaches and metrics for community health, including but not
restricted to community growth or diversity.
*
Roles and participation profiles in communities building and
maintaining KBs.
*
Frameworks and approaches to support group decision-making and
resolve conflicts.

Dear all,
Exactly 1 year ago, we presented DBpedia Archivo
https://archivo.dbpedia.org <https://archivo.dbpedia.org/>(paper
<https://svn.aksw.org/papers/2020/semantics_archivo/public.pdf>, video
<https://2020-eu.semantics.cc/dbpedia-archivo-web-scale-interface-ontology-a…>)
at SEMANTiCS 2020. Our initial vision was to create a fully automated,
persistent Ontology Archive that serves as a backbone for the Semantic
Web and brings a convenient and stable interface to ontology users. We
are listing some points that we would judge as great successes and
highlights of running Archivo for over a year. Read the full list on our
blog <https://www.dbpedia.org/blog/dbpedia-archivo-1-year-retrospective/>.
September 9th, 2021 at 1pm CEST: In particular, we would like to invite
you to the DBpedia Ontology session
<https://www.dbpedia.org/events/dbpedia-day-semantics-2021/>at the
DBpedia Day at SEMANTiCS 2021 <https://2021-eu.semantics.cc/>to discuss
the future roadmap for Archivo as a Unified Semantic Ontology Space
(USOS) and what the role of the DBpedia Ontology will be in the Semantic
Web.
The session will host impulse talks with ample room for discussion. For
the first time in the history of the Semantic Web, Archivo offers the
possibility to create a Unified Semantic Ontology Space (USOS), a
holistic view over all available ontologies. Instead of soft and fuzzy
principles such as FAIR, we will discuss hard, implementable criteria to
evaluate ontologies in preparation of a well-defined, measurable
standard, which will ultimately yield better and reliable ontologies for
industrial applications. Another topic is the central collaboration on
links and mappings between ontologies to create a more dense and
well-connected web of ontologies. Join the discussion and register here
https://www.dbpedia.org/events/dbpedia-day-semantics-2021/
<https://www.dbpedia.org/events/dbpedia-day-semantics-2021/>.
Stay tuned and stay safe!

The Journal of Web Semantics (JWS) invites submissions for a special
issue on Community-based Knowledge Bases and Knowledge Graphs, edited by
Tim Finin, Sebastian Hellmann, David Martin, and Elena Simperl. (contact
email: cbkb(a)cs.umbc.edu <mailto:cbkb@cs.umbc.edu>) Submissions are due
by November 01, 2021. Please see the JWS post here:

Introduction
Community-based knowledge bases (KBs) and knowledge graphs (KGs) are
critical to many domains. They contain large amounts of information,
used in applications as diverse as search, question-answering systems,
and conversational agents. They are the backbone of linked open data,
helping connect entities from different datasets. Finally, they create
rich knowledge engineering ecosystems, making significant, empirical
contributions to our understanding of KB/KG science, engineering, and
practices. From here forward, we use "KB" to include both knowledge
bases and knowledge graphs. Also, "KB" and "knowledge" encompass both
ontology/schema and data.
Community-based KBs come in many shapes and sizes, but they tend to
share a number of commonalities:
*
They are created through the efforts of a group of contributors,
following a set of agreed goals, policies, practices, and quality norms.
*
They are available under open licenses.
*
They are central to knowledge-sharing networks bringing together
various stakeholders.
*
They serve the needs of a community of users, including, but not
restricted to, their contributor base.
*
Many draw their content from crowdsourced resources (such as
Wikipedia, OpenStreetMap).
Examples of community-based KBs include Wikidata, DBpedia, ConceptNet,
GeoNames, FrameNet, and Yago. This special issue will highlight recent
research, challenges, and opportunities in the field of community-based
KBs and the interaction and processes between stakeholders and the KBs.
We welcome papers on a wide variety of topics. Papers that focus on the
participation of a community of contributors are especially encouraged.
Topics of interest
We are looking for studies, frameworks, methods, techniques and tools on
topics such as the following:
*
The impact of community involvement on characteristics of KBs such
as requirements, design, technology choices, policies, etc. For
example, how are KB characteristics driven by the community and
reflective of the community's needs?
*
Conversely, the impact of KB characteristics on community
involvement. For example, how do changes in these characteristics
affect the participation and behavior of members of the community?
*
Organizational challenges and solutions in developing and managing
community-based KBs.
*
Technical challenges and solutions in community-based KBs,
concerning a technical area such as:
o
Representation of knowledge and logical foundations
o
Reasoning, querying, and constraint-checking
o
Knowledge acquisition
o
Knowledge preparation (e.g., cleaning, deduplication, alignment,
merging)
o
Maintaining consistency with external sources
o
Representing and managing metadata (including issues involved in
adding metadata to relation instances)
o
Provenance
o
Quality assurance
*
User interfaces and experience, both for contributing to the KB and
using it, by different user groups.
*
Implemented metrics and quality tests to guide the community in
improving KG quality and expanding KG coverage.
*
Achieving and managing knowledge diversity, for instance, in the
form of multilinguality, multi-cultural coverage, multiple points of
view, and a diverse and inclusive contributor base.
*
Detecting and avoiding malicious, inappropriate, and misleading
content in community-based KBs.
*
Biases in community-based KBs and their impact on downstream uses of
KB content.
*
Community-based KBs in science, medicine, law, government, or other
domains.
*
Handling specialized types of knowledge (such as commonsense,
probabilistic, or linguistic knowledge) in a community setting.
*
Methods and tools to manage KB evolution, including change
detection, change management, conflict resolution, visualization of
change history.
*
Tools and affordances supporting community or collaborative
activities, including discussions, feedback, decision making, task
allocation, etc.
*
Motivations and incentives affecting community participation.
*
Approaches and metrics for community health, including but not
restricted to community growth or diversity.
*
Roles and participation profiles in communities building and
maintaining KBs.
*
Frameworks and approaches to support group decision-making and
resolve conflicts.
