Last week, I visited the 11th Metadata and Semantics Research Conference (MTSR2017) in Tallinn, Estonia. This conference brings together computer scientists. information scientists and people from the domain of digital libraries to discuss their work in metadata and semantics. The 2017 edition of the conference draws around 70 people which is a great size for a single-track conference with lively discussions. The paper included interesting tracks on Cultural Heritage and Library (meta)data as well as one on Digital Humanities.
On the last day I presented our paper “Enriching Media Collections for Event-based Exploration” [draft pdf], co-authored with the people in the CLARIAH and DIVE+ team working on data enrichment and APIs: Liliana Melgar, Oana Inel Carlos Martinez Ortiz, Lora Aroyo and Johan Oomen. The slides for the presentation can be found here on slideshare. We were very happy to hear that our paper was presented the MTSR2017 Best Paper Award!
In the paper, we present a methodology to publish, represent, enrich, and link heritage collections so that they can be explored by domain expert users. We present four methods to derive events from media object descriptions. We also present a case study where four datasets with mixed media types are made accessible to scholars and describe the building blocks for event-based proto-narrativesin the knowledge graph
The paper was co-authored by Victor de Boer, Oana Inel, Lora Aroyo, Chiel van den Akker, Susane Legene, Carlos Martinez, Werner Helmich, Berber Hagendoorn, Sabrina Sauer, Jaap Blom, Liliana Melgar and Johan Oomen
At the Digital Humanities Benelux 2017 conference, the e-humanities Events working group organized a panel with the titel “A Pragmatic Approach to Understanding and Utilizing Events in Cultural Heritage”. In this panel, researchers from Vrije Universiteit Amsterdam, CWI, NIOD, Huygens ING, and Nationaal Archief presented different views on Events as objects of study and Events as building blocks for historical narratives.
The session was packed and the introductory talks were followed by a lively discussion. From this discussion it became clear that consensus on the nature of Events or what typology of Events would be useful is not to be expected soon. At the same time, a simple and generic data model for representing Events allows for multiple viewpoints and levels of aggregations to be modeled. The combined slides of the panel can be found below. For those interested in more discussion about Events: A workshop at SEMANTICS2017 will also be organized and you can join!
We are excited to announce that DIVE+ has been awarded the Grand Prize at the LODLAM Summit, held at the Fondazione Giorgio Cini this week. The summit brought together ~100 experts in the vibrant and global community of Linked Open Data in Libraries, Archives and Museums. It is organised bi-annually since 2011. Earlier editions were held in the US, Canada and Australia, making the 2017 edition the first in Europe.
The Grand Prize (USD$2,000) was awarded by the LODLAM community. It’s recognition of how DIVE+ demonstrates social, cultural and technical impact of linked data. The Open Data Prize (of USD$1,000) was awarded to WarSampo for its groundbreaking approach to publish open data
.Five finalists were invited to present their work, selected from a total of 21 submissions after an open call published earlier this year. Johan Oomen, head of research at the Netherlands Institute for Sound and Vision presented DIVE+ on day one of the summit. The slides of his pitch have been published, as well as the demo video that was submitted to the open call. Next to DIVE+ (Netherlands) and WarSampo (Finland) the finalists were Oslo public library (Norway), Fishing in the Data Ocean (Taiwan) and Genealogy Project (China). The diversity of the finalists is a clear indication that the use of linked data technology is gaining momentum. Throughout the summit, delegates have been capturing the outcomes of various breakout sessions. Please look at the overview of session notes and follow @lodlam on Twitter to keep track.
DIVE+ is an event-centric linked data digital collection browser aimed to provide an integrated and interactive access to multimedia objects from various heterogeneous online collections. It enriches the structured metadata of online collections with linked open data vocabularies with focus on events, people, locations and concepts that are depicted or associated with particular collection objects. DIVE+ is the result of a true interdisciplinary collaboration between computer scientists, humanities scholars, cultural heritage professionals and interaction designers. DIVE+ is integrated in the national CLARIAH (Common Lab Research Infrastructure for the Arts and Humanities) research infrastructure.
DIVE+ is a collaborative effort of the VU University Amsterdam (Victor de Boer, Oana Inel, Lora Aroyo, Chiel van den Akker, Susane Legene), Netherlands Institute for Sound and Vision (Jaap Blom, Liliana Melgar, Johan Oomen), Frontwise (Werner Helmich), University of Groningen (Berber Hagendoorn, Sabrina Sauer) and the Netherlands eScience Centre (Carlos Martinez). It is supported by CLARIAH and NWO.
The LODLAM Challenge was generously sponsored by Synaptica. We would also like to thank the organisers, especially Valentine Charles and Antoine Isaac of Europeana and Ingrid Mason of Aarnet for all of their efforts. LODLAM 2017 has been a truly unforgettable experience for the DIVE+ team.
On Tuesday 13 June 2017, the second CLARIAH Linked Data workshop took place. After the first workshop in September which was very much an introduction to Linked Data to the CLARIAH community, we wanted to organise a more hands-on workshop where researchers, curators and developers could get their hands dirty.
The main goal of the workshop was to introduce relevant tools to novice as well as more advanced users. After a short plenary introduction, we therefore split up the group where for the novice users the focus was on tools that are accompanied by a graphical user interface, like OpenRefine and Gephi; whereas we demonstrated API-based tools to the advanced users, such as the CLARIAH-incubated COW, grlc, Cultuurlink and ANANSI. Our setup, namely to have the participants convert their own dataset to Linked Data and query and visualise, was somewhat ambitious as we had not taken into account all data formats or encodings. Overall, participants were able to get started with some data, and ask questions specific to their use cases.
It is impossible to fully clean and convert and analyse a dataset in a single day, so the CLARIAH team will keep investigating ways to support researchers with their Linked Data needs. For now, you can check out the CultuurLink slidesand tutorial materials from the workshop and keep an eye out on this website for future CLARIAH LOD events.
Last week, the Volkswagen Stiftung-funded “Mixed Methods’ in the Humanities?” programme had its kickoff meeting for all funded projects in in Hannover, Germany. Our ArchiMediaL project on enriching and linking historical architectural and urban image collections was one of the projects funded through this programme and even though our project will only start in September, we already presented our approach, the challenges we will be facing and who will face them (our great team of post-docs Tino Mager, Seyran Khademi and Ronald Siebes). Other interesting projects included analysing of multi-religious spaces on the Medieval World (“Dhimmis and Muslims”); the “From Bach to Beatles” project on representing music and schemata to support musicological scholarship as well as the nice Digital Plato project which uses NLP technologies to map paraphrasing of Plato in the ancient world. An overarching theme was a discussion on the role of digital / quantitative / distant reading methods in humanities research. The projects will run for three years so we have some time to say some sensible things about this in 2020.
An important role in the interpretation of cultural heritage collections is played by ‘historic events’. In the SEMANTiCS workshop Events2017: Understanding Events Semantics in Cultural Heritage, to be held on 11 Sept 2017, we will investigate and discuss challenges around identifying, representing, linking and reasoning about historical events. We invite full papers (8p) as well as short papers (4p) on this topic.
The call for papers is out now. You have until July 10, 2017 to submite your contribution. Contributions can include original research papers, position papers, or papers describing tools, demonstrators or datasets. Accepted contributions will be published on the CEUR-WS website (or equivalent).
I made some exercises a while ago but keep re-using them for SPARQL tutorials and hands on sessions. I now moved them to a new webpage. This page presents SPARQL queries in increasing complexity that one can copy-paste into the interactive query field of the Dutch Ships and Sailors live triple store.
This is a first post in a new series on VU Semantic Web reading club. During this weekly reading club we discuss a research paper related to Semantic Web, Human Computation or Computer Science in general. Every week, one group member selects and prepares a paper to discuss. This week it was my time and I chose a paper from 2013: “Dance in the World of Data and Objects” by Katerina El Raheb and Yannis Ioannidis (full citation and abstract below). The paper presents the need for (OWL) ontologies for dance representation. A quite nice slide deck supporting the paper is found here.
Computer-interpretable knowledge representations for dance is something I have been thinking about for a while now. I am mostly interested in representations that actually match the conceptual level at which dancers and choreoraphers communicate and how these are related to low-level representations such as Labanotation. I am currently supervising two Msc students on this topic.
The paper by El Raheb and Ioannidis and our discussion afterwards outlined the potential use of such a formal representations for:
Archiving dance and for retrieval. This is a more ‘traditional’ use of such representations in ICT for Cultural Heritage. An interesting effect of having this represented using standard semantic web languages is that we can connect deep representations of choreographers to highly heterogeneous knowledge about for example dance or musical styles, locations, recordings, emotions etc. An interesting direct connection could be to Albert Merono’s RDF midi representations.
For dance analysis. By having large amounts of data in this representation, we can support Digital Humanities research. Both in more distant reading, but potentially also more close analysis of dance. Machine learning techniques could be of use herer.
For creative support. Potentially very interesting is to investigate to what extent representations of dance can be used to support the creative process of dancers and choreographers. We can think of pattern-based adaptations of choreographies.

Abstract: In this paper, we discuss the challenges that we have faced and the solutions we have identified so far in our currently on-going effort to design and develop a Dance Information System for archiving traditional dance, one of the most significant realms of intangible cultural heritage. Our approach is based on Description Logics and aims at representing dance moves in a way that is both machine readable and human understandable to support semantic search and movement analysis. For this purpose, we are inspired by similar efforts on other cultural heritage artifacts and propose to use an ontology on dance moves (DanceOWL) that is based on the Labanotation concepts. We are thus able to represent dance movement as a synthesis of structures and sequences at different levels of conceptual abstraction, which serve the needs of different potential users, e.g., dance analysts, cultural anthropologists. We explain the rationale of this methodology, taking into account the state of the art and comparing it with similar efforts that are also in progress, outlining the similarities and differences in our respective objectives and perspectives. Finally, we describe the status of our effort and discuss the steps we intend to take next as we proceed towards the original goal.
