European Open Data Portal and Policy Compass: from national Open Data reposit...OW2
In November 2015 the European Commission officially lunched the European Data Portal http://www.europeandataportal.eu . The mission of the portal is to become the catalogue of all European public data providing them in all official languages of the European Union. The portal is harvesting metadata from heterogeneous open data portals of 28 EU and other 11 European countries. It lists over 580 000 datasets and it is the biggest Open Data portal worldwide. From the techincal perspective, it is the first official Open Data portal implementing the new DCAT Application Profile specification.
The portal is the place to find European public data and it is a basis for other innovative services. One of them is Policy Compass https://policycompass.eu. It brings together open public data, social media, e-participation platforms, causal models, and argumentation technology for constructing, sharing, visualizing and debating progress metrics and impacts of policies.
Both portals are Open Source. They provide rich APIs and may become a data source for other applications.
An overview of the ICARUS project provided during the European Big Data Value Forum, Parallel Session 1.3 “Transforming Transport”, on November 12th, 2018, in Vienna.
Meemoo manages a large quantity of mainly audiovisual material from more than 170 partners in cultural heritage and media. More than 6 million objects are currently stored, ranging from digitised newspapers, photos, videos, and audio. In addition, a number of access platforms make the digitised content available to specific target groups, including teachers, students, professional re-users, or the public.
Metadata is a key element in all of meemoo’s processes. An important part of our activities is to collect, integrate, manage, and search a large variety of heterogeneous metadata across the archived content. The scale of this has increased enormously, so a good and integrated approach is needed to deal with the amount of metadata, its need for flexibility, and how easy it is to find. One of the specific challenges is modelling and storing data from machine learning algorithms (speech recognition, face detection and entity recognition) for reuse.
In this talk, we will discuss the key points and lessons learned from implementing the new metadata roadmap at Meemoo, which is focused on a Knowledge Graph-based infrastructure. The goal of the roadmap is to establish a better data practice within the organization and offer application-independent, uniform access to (meta)data that is spread across various systems and formats.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Event model is weak:
missing rich categories, the performers and artists, etc.
the user cannot reuse existing events
Task: design a Facebook application that
allows for creating and sharing events, and
closely interacting with EventMedia
Task: crawl public events and related data
hosted by Facebook using the Graph API in
order to continuously feed EventMedia
