Roadmap from ESEPaths to EDMPaths: a note on representing annotations resulting from automatic enrichment - Aitor Soroa, Eneko Agirre, Arantxa Otegi and Antoine Isaac
This document is a case study on using the Europeana Data Model (EDM) [Doerr et al., 2010] for representing annotations of Cultural Heritage Objects (CHO). One of the main goals of
the PATHS project is to augment CHOs (items) with information that will enrich the user’s experience. The additional information includes links between items in cultural collections and from items to external sources like Wikipedia. With this goal, the PATHS project has applied Natural Language Processing (NLP) techniques on a subset of the items in Europeana.

Large amounts of cultural heritage material are nowadays available through online digital library portals. Most of these cultural items have short descriptions and lack rich contextual information. The PATHS project has developed experimental enrichment services. As a proof of concept, this paper presents a web service prototype which allows independent content providers to enrich cultural heritage items with a subset of the full functionality: links to related items in the collection and links to related Wikipedia articles. In the future we plan to provide more advanced functionality, as available offline for PATHS.

Implementing Recommendations in the PATHS system, Paul Clough, Arantxa Otegi, Eneko Agirre and Mark Hall, paper presented at the Supporting Users Exploration of Digital Libraries, SUEDL 2013 workshop, during TPDL 2013 in Valetta, Malta
In this paper we describe the design and implementation of nonpersonalized recommendations in the PATHS system. This system allows users to explore items from Europeana in new ways. Recommendations of the type “people who viewed this item also viewed this item” are powered by pairs of viewed items mined from Europeana. However, due to limited usage data only 10.3% of items in the PATHS dataset have recommendations (4.3% of item pairs visited more than once). Therefore, “related items”, a form of contentbased recommendation, are offered to users based on identifying similar items. We discuss some of the problems with implementing recommendations and highlight areas for future work in the PATHS project.

In this paper we present the results of the user requirements and interface design phase for a prototype system, designed to enhance interaction with cultural heritage collections
online through means of a pathway metaphor. We present a single user interaction model that supports various work and
information seeking tasks undertaken by both expert and non
-expert users within the context of collection exploration and path creation. The user interaction model is shown to enable seamless movement between interaction modes, with the potential over time to encourage deeper engagement and learning.
Generating Paths through Cultural Heritage Collections Latech2013 paperpathsproject
Generating Paths through Cultural Heritage Collections, Samuel Fernando, Paula Goodale, Paul Clough, Mark Stevenson, Mark Hall and Eneko Agirre. Paper presented at Latech 2013
Cultural heritage collections usually organise sets of items into exhibitions or guided tours. These items are often accompanied by text that describes the theme and topic of the exhibition and provides background context and details of connections with other items. The PATHS project brings the idea of guided tours to digital library collections where a tool to create virtual paths are used to assist with navigation and provide guides on particular subjects and topics. In this paper we characterise and analyse paths of items created by users of our online system.

The aim of the PATHS project is to enable exploration and discovery within cultural heritage collections. In order to support this the project developed a range of enrichment techniques which augmented these collections with additional information to enhance the users’ browsing experience. One of the demonstration systems developed in PATHS makes use of content from Europeana. This document summarises the semantic enrichment techniques developed in PATHS, with particular reference to their application to the Europeana data.

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

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).

3. Information access in cultural heritage
• Significant amounts of Cultural Heritage material
available online
– Web portals, digital libraries, Wikipedia …
• Users find it difficult to navigate and interpret the
wealth of information
– users are normally not subject experts
– systems offer limited support for knowledge exploration and
discovery
6. PATHS
http://www.paths-project.eu
• Supporting user’s knowledge
discovery and exploration
• Use of pathways/trails to
navigate and explore the
information space
• Personalisation to adapt views/
paths to specific users or
groups of users
• Links to items within the
information space and
externally to contextualise and
aid interpretation
7. PATHS: Basic facts
• STREP funded under the European Commission's
Seventh Framework Programme
• 36 months
– 1st January 2011 to 31st December 2013
• Budget – 3,199,299 euros in total
– 2,300,000 euros EU grant
• 6 partners in 5 countries
8. PATHS consortium
• Universities
– Sheffield University (co-ordinator)
– Universidad del Pais Vasco
• Technology enterprises
– i-sieve technologies Ltd
– Asplan Viak Internet Ltd
• Cultural heritage enterprises
– MDR Partners
– Alinari 24 Ore Spa
• With an additional content provider
– Europeana
9. Project objectives
• Analysis of users’ requirements for discovering knowledge in
Cultural Heritage collections and construction of pathways/trails
• Automated organisation and enrichment of Cultural Heritage content
for use within a navigation system
• Implementation of a system for navigating Cultural Heritage
resources
• Techniques for providing personalised access to Cultural Heritage
content (e.g. recommender systems)
• Porting the navigation system for use on mobile devices and
Facebook
• Evaluation with user groups and in field trials
10. Research areas
• Information Access
– user-driven navigation through collections
– knowledge of users’ requirements for access to cultural heritage
collections
– modeling of user preferences and context
• Educational Informatics
– adapting to individual learners in relation to being directed and
being allowed the freedom to explore autonomously
• Content Interpretation and Enrichment
– representation and sharing of information about items in Digital
Libraries
– identifying background information related to the items in cultural
heritage collections (e.g. links to Wikipedia pages)
11. Pathways for navigation
• Navigation through a collection via metaphor of “pathways”
• A path is a ‘route’ through an information space
– defined as collections of cultural heritage resources
– consists of items, links connecting them and narrative
Presentation at Glasgow University, 14th March 2011
12. Guided and user generated paths
• Users can follow pre-defined “guided paths”
– created by domain experts, such as scholars or teachers
• Provide an easily accessible entry point to the collection
– can be followed in their entirety or left at any point
• Users can also create and share their own paths
• Paths can be based around any theme
– artist and media (“paintings by Picasso”)
– historic periods (“the Cold War”)
– places (“Venice”)
– famous people (“Muhammed Ali”)
– or any other topic (e.g. “Europe”, “food”)
13. Paths and trails have been studied in many fields
• Trails (Memex, 1945)
– Associative trails explicitly created by users forming links
between stored materials to help others navigate
• Destinations (search engines and web analytics)
– Origin/landing page (from query), intermediate pages and
destination page
• Search strategies (information seeking)
– Users moving between information sources, perhaps due to
changes in their information needs
• Guided tours (hypertext)
– authors create sequence of pages useful to others (manual)
– automatically generated trails to assist with web navigation
– used in educational informatics and cultural heritage
14. Learning and knowledge discovery
• A particular area of focus in PATHS
– Aims to help people to learn and discover new knowledge as
they use cultural heritage resources
• People learn and solve problems differently
– some people require a lot of guiding; others are self-directed
– some people welcome irrelevant material; others are intolerant
– some people creatively explore and come up with new ideas;
others want to answer a set problem
• Users may perform information seeking
– must navigate through information spaces
– different people may require different levels of assistance
