When the Nobel Prize winners for 2013 are announced in the fall, perhaps there also will be some challenges issued to the worldwide community of data enthusiasts to see what they can do with open Linked Data about the prizes that have been awarded since the beginning of the 20th century.
Right now that’s just on the wish lists of Matthias Palmér and Hannes Ebner, co-founders of MetaSolutions AB, a spin-off from the Royal Institute of Technology in Stockholm and Uppsala University focused on semantic and scalable web apps. But a solid start has been made through their work with Nobel Media AB, which develops and manages programs, productions and media rights of the Nobel Prize within the areas of digital and broadcast media, including the Nobelprize.org domain, on the Nobel Prize Linked Data set.
There’s more than one way to get a taxonomy. A company can go out and buy one for its industry, for instance, but the risk is that the terms may not relate to how it talks about content in its own organization, and the hierarchy may not be the right fit either. That sets up two potential outcomes, says Chris Riley, VP of marketing at Pingar: You wind up having to customize it, or with users who just ignore it.
It’s possible to build one, but that’s a big job and a costly one, too – especially for many enterprises, where there hasn’t traditionally been a focus on structuring content and so the skills to do it aren’t necessarily there. While industries like publishing, oil and gas, life sciences, and pharma have that bent, many other verticals do not. In fact, Riley notes, they may realize they have a content organization problem, but not that what they’d benefit from to address it even goes by the name ‘taxonomy.’
Pingar’s looking to help out those enterprises that want to bring organization to their content, whether or not they’re familiar with the concept of a taxonomy. It just launched its automated Taxonomy Generator Service that uses an organization’s own content to build a taxonomy that mirrors its own way of talking about things and its understanding of relationships between child and parent terms.
EventMedia Live, Winner of ISWC Semantic Web Challenge, Starts New Project With Nokia Maps, Extends Architecture Flexibility
The winner of the Semantic Web Challenge at November’s International Semantic Web Conference (ISWC) was EventMedia Live, a web-based environment that exploits real-time connections to event and media sources to deliver rich content describing events that are associated with media, and interlinked with the Linked Data cloud.
This week, it will begin a one-year effort under a European Commission-funded project to align its work with the Nokia Maps database of places, so that mobile users of the app can quickly get pictures of these venues that were taken by users with EventMedia’s help.
A project of EURECOM, a consortium combining seven European universities and nine international industrial partners, EventMedia Live has its origins in the “mismatch between those sites specializing in announcing upcoming events and those other sites where users share photos, videos and document those events,” explains Raphaël Troncy, assistant professor at the EURECOM: School of Engineering & Research Center, Multimedia Communications, and one of the project’s leaders.
DBpedia has begun an Evaluation Campaign with the aim of “evaluating DBpedia resources in order to assess and thereby improve the quality of DBpedia.” It works like this: “First, please authenticate yourself with a google account. This will not only help prevent spam but also help us keep track of how many resources you evaluated. After you click ‘Start’, you will be provided with a list of classes from DBpedia wherein you may choose the ones you are most familiar with. There are three options: (1) Any: where a completely random resource will be retrieved, (2) Class: where you have the option to choose any class from the DBpedia ontology and a random resource belonging to that class will be retrieved, (3) Manual: where you can manually put in the DBpedia URI of a resource of your choice.” Read more
I was toying with another title for this post – Yet Another Perfect Storm, but I think that particular metaphor (although appropriate here) has been somewhat over done. So what sparked this one then?
I am on the long flight back from the Semantic Tech & Business Conference in San Francisco to the good ol’ UK, to see how they got on with the Queen’s Diamond Jubilee festivities. I am reflecting on what my week at the conference has told me. It has told me that things are a changing – I got that impression last year too, but more so this year. Obviously, from the title of this post, it has something to do with Schema.org, Wikidata, and the Google Knowledge Graph….
Paul Wilton was Technical and development lead for semantic publishing at BBC News and Sport Online during the 2010 World Cup. Currently he is the Technical architect at Ontoba. In this interview, a supplement to “Dynamic Semantic Publishing for Beginners”, Paul describes the current landscape for DSP as it applies to news organizations.
Q. Are you seeing a wide disparity in the way that news organizations have approached the creation and use of semantically-linked (or annotated) content?
A. Actually the pattern and often the (general) technical architecture is surprisingly similar. Where things differ are the applications, models used and instance data. This is undoubtedly bleeding edge technology, and typically the impetus to begin investigating the use of linked data, RDF and semantics in the technology stack has come from within the Information Architecture and R&D teams, not from the offices of the CTO/CIO. Maybe this is starting to change now.
Q. Do many news organizations have the resources (staff and/or Content Management Systems) that are able to publish and use semantic data?
A. Not in our experience, but this shouldn’t be a barrier to integrating semantic technologies and publishing linked data.
The key components to adopting semantic publishing – a semantic repository (triple store); appropriate linked data sets; and the ability to semantically annotate your content – can be built alongside an existing Content Management System. Read more
