New "Turtle all the way down" version of the TRAK architecture framework. Provides semantically accurate description of conformance claim. Also means to describe a fault tree. More than a little added Turtle/RDF examples of TRAK architecture views.

An example of a TRAK SV-11 Solution Event causes architecture view. This architecture view describes a simple fault tree where if any of 3 child events occurs the top event occurs.

The example uses an n-ary tuple to link the top event to the collection of child events which are all joined using a logical 'OR' relationship.

A fragment of a TRAK MV-04 Assurance architecture view. This architecture view presents a single claim of conformance which is formed from 2 parts:

1) a Conformance Assertion Triple - Software.'XML Studio' satisfies Standard. 'ISO?IEC 14882:2024 Programming Language C++'

2) a Conformance Claim triple - Claim 'XML Studio fully complies with ISO/IEC 14882:2024' about Conformance Assertion Triple

i.e. the object of the triple starting with the Claim is itself a triple.

Yesterday @royaheeee and I presented our paper, DAGE: DAG Query Answering via Relational Combinator with Logical Constraints, at #WWW2025. Existing query answering methods over knowledge graph embedding were limited to decomposable queries, called tree-form queries. Our method provides embeddings for relations that correspond to conjunctions of relations. This idea increases the expressive power of existing query embedding methods.

In our ISE seminar today our colleague Hossein Beygi Nasrabadi is presenting the current state of the #NFDIMatWerk ontology - MWO. In the beginning, he is introducing two large #materialsscience related projects on digitalisation and research data management: Platform Material Digital (PMD) and NFDI-MatWerk.

#IchForscheGernInWien #TopForschungWien #Wien

Last week we launched a campaign to highlight research in Vienna by telling our own "research stories", which I gladly would like to highlight again - this time in English 🙂:

As professor of Data and Knowledge Engineering at the Vienna University of Economics and Business, I do research in the field of Artificial Intelligence and intelligent data integration with the aim of making the increasingly unmanageable amounts of data usable for both humans *and* machines. As a focus technology we particularly investigate the role #knowledgegraphs in combining symbolic and subsymbolic AI.

Times have become more difficult and darker for research in many countries. Here in Vienna, the conditions for science and research have constantly improved over the last years. I am convinced that this will continue and that the corresponding efforts and support will be even greater in the future. As a member of the Viennese research community, I will actively participate in this endeavour.

Because I like living and researching in Vienna: being originally from Vienna, after several years abroad, roughly 15 years ago I returned and found a new "old" home, with lots of colleagues not only amongst researchers, but also in the public adminstration, in my university and research funding agencies who *care* to improve the conditions for researchers, create new opportunities and networks. Thanks to all these people, it is especially important in times like these to #standtogether for believing in and advancing #science!

Für die Forschung sind die Zeiten in vielen Ländern schwieriger und finsterer geworden. Hier in Wien wurden die Bedingungen für Wissenschaft und Forschung in den letzten Jahren immer besser. Ich bin überzeugt davon, dass das auch so bleibt und dass die entsprechenden Anstrengungen und Unterstützungen in Zukunft noch stärker ausfallen werden. Als Mitglied der Wiener Forschungscommunity werde ich daran mitwirken. Denn ich lebe und forsche gerne in Wien!
