dcat: An RDF vocabulary for interoperability of data cataloguesRichard Cyganiak
Governments produce large amounts of valuable data, such as spreadsheets and maps, as part of daily operations and decision-making. This data can be useful to many citizens and organizations beyond the government, and it is ultimately the citizen who has paid for producing it. More and more governments make this data publicly available through data catalogs, such as data.gov, data.gov.uk, or statcentral.ie. This slide set introduces dcat, a unified format for publishing the metadata of such catalogs, that supports the querying, federation, consumption and archival of these valuable data assets.
General introduction to DERI (Digital Enterprise Research Institute). DERI is the largest research center in the worked dedicated to research in semantic web technologies. It is hosted at NUI Galway in Ireland

The RDF Working Group at W3C has been busy with an update to the RDF standards, and this work is now nearing its end. Here I summarise what's new, what's been controversial, and also give a very brief intro to the RDF data model.
Semantic Web technologies (such as RDF and SPARQL) excel at bringing together diverse data in a world of independent data publishers and consumers. Common ontologies help to arrive at a shared understanding of the intended meaning of data.
However, they don’t address one critically important issue: What does it mean for data to be complete and/or valid? Semantic knowledge graphs without a shared notion of completeness and validity quickly turn into a Big Ball of Data Mud.
The Shapes Constraint Language (SHACL), an upcoming W3C standard, promises to help solve this problem. By keeping semantics separate from validity, SHACL makes it possible to resolve a slew of data quality and data exchange issues.

Unleashing the Power of Vector Search in .NET - DotNETConf2024.pdfLuigi Fugaro
Redis OM .NET has evolved to embrace the transformative world of vector database technology, now supporting Redis vector search and seamless integration with OpenAI, Azure OpenAI, Hugging Face, and ML.NET. This talk highlights the latest advancements in Redis OM .NET, focusing on how it simplifies the complex process of vector indexing, data modeling, and querying for AI-powered applications. Vector databases are redefining data handling, enabling semantic searches across text, images, and audio encoded as vectors. Redis OM .NET simplifies this innovative approach, making it accessible even for those new to vector data. We will explore the new capabilities of Redis OM .NET, including intuitive vector search interfaces and semantic caching, which reduce the overhead of large language model (LLM) calls.

RESEARCH REPOSITORIES AND DATAVERSE: NEGOTIATING METADATA, VOCABULARIES AND DOMAIN NEEDS
Vyacheslav Tykhonov, Jerry de Vries, Eko Indarto, Femmy Admiraal, Mike Priddy, and Andrea Scharnhorst: Flexibility in Metadata Schemes and Standardisation: the Case of CMDI and the DANS EASY Research Data Repository
Abstract:
The development of metadata schemes in data repositories (and other content providers) has always been a process of negotiation between the needs of the designated user communities and the content of the collection on the one side and standards developed in the field. Automatisation has both enabled and enforced standardisation and alignment of metadata schemes (see as an example). But, while designated user communities turned from being local users to global ones (due to web services), their specific needs have not vanished. Technology offers possibilities to give the aforementioned negotiation a new form. In this presentation, we present the Dataverse platform, used by many data repositories. We show - using the case of the CMDI metadata and the CLARIN (Common Language Resources and Technology Infrastructure)community - how the Dataverse common core set of metadata called Citation Block can be extended with custom fields defined as a discipline specific metadata block. In particular, we show how these custom fields can be connected to a distributed network of authoritative controlled vocabularies. So, that at the end semantic search is possible. The presentation highlights opportunities and challenges, based on our own experiences. Related work has been presented at the CLARIN Annual Conference 2021 (see Proceedings).

SAP Analytics Cloud: Haben Sie schon alle Datenquellen im Live-Zugriff?Denodo
Watch full webinar here: https://bit.ly/3hfEO6d
Die SAP Analytics Cloud (kurz "SAC" genannt) ist ein Service in der Cloud, der umfangreiche Analysefunktionen für Benutzer in einem Produkt bereit stellt. Wie immer bei der SAP ist auch die SAC technologisch gut integriert in die Welt der SAP Systeme.
Doch die Daten, die Unternehmen heutzutage analysieren möchten, befinden sich sehr häufig in den unterschiedlichsten Datenquellen: In relationalen Datenbanken, in Data Lakes, in Webservices, in Dateien, in NoSQL Datenbanken,... Und so stellt sich zwangsläufig die Frage, wie Sie aus der SAC heraus alle Daten konnektieren, transformieren und kombinieren können. Und das möglichst live, d.h. mit Abfragen auf Echtzeit-Daten! Hier kommt die Datenvirtualisierung ins Spiel: Sie bietet Anwendungen (so auch der SAC) einen einheitlichen, integrierten und performanten Zugriff auf SAP Daten und non-SAP Daten.
Erfahren Sie in diesem Webcast:
- Wie die Datenvirtualisierung funktioniert (in a Nutshell)
- Wie Sie aus der SAC heraus auf alle ihre Daten in Echtzeit zugreifen können ("Live Data Connection" genannt)
- Wie die Datenvirtualisierung die Performance auch für Abfragen auf grossen Datenmengen optimiert
A changing market landscape and open source innovations are having a dramatic impact on the consumability and ease of use of data science tools. Join this session to learn about the impact these trends and changes will have on the future of data science. If you are a data scientist, or if your organization relies on cutting edge analytics, you won't want to miss this!
