Some highlights of the software and demos made in the group.




SWI-Prolog offers a comprehensive free Prolog environment. SWI-Prolog is the most widely used Prolog implementation in the world. SWI-Prolog on github

ClioPatriaCliopatria: the SWI-RDF toolkit

ClioPatria is a SWI-Prolog application that integrates SWI-Prolog’s libraries for RDF and HTTP services into a ready to use (semantic) web server. The core server has an integrated package manager that allows distributing and using add-on libraries: CPACK. Cliopatria on GitHub

amalgameAmalgame: concept alignment toolkit

Amalgame provides a web-based interactive platform for creating, analyzing and evaluating vocabulary alignments.  Amalgame is implemented by using common web technology on the client (e.g. HTML,CSS,AJAX and the YUI toolkit) and SWI-Prolog’s ClioPatria platform on the server. Amalgame on GitHub


Dutch Ships and Sailors (DSS) Semantic Layer:
Dutch Ships and Sailors provides an infrastructure for maritime historical datasets, linking correlating data through semantic web technology. It brings together datasets related to recruitment and shipping in the East-India trade (mainly 18th century) and in the shipping of the northern provinces of the Netherlands (mainly 19th century).

europeanaEuropeana Semantic Layer:
This triple store hosts a number of datasets converted and made public in the context of the EuropeanaConnect project




Verrijkt Koninkrijk Semantic Layer:
This triple store links the seminal work “The Kingdom of the Netherlands in the Second World War” to the Web of Data, using SKOS vocabularies as stepping stones


PoliMedia links the minutes of the debates in the Dutch Parliament (Dutch Hansard) to the databases of historical newspapers and ANP radio bulletins to allow cross-media analysis of coverage in a uniform search interface.


Accurator :
Accurator is platform that enables Web users to help museum professionals with describing museum collection items by providing expert knowledge. This could, for example, be the annotation of the depicted species of an animal or a plant. Apart from enhancing the descriptions of the collection items, this information can be used to facilitate searching the museum’s collection. Accurator on GitHub

DIVE Browser:
DIVE is a linked-data digital cultural heritage collection browser. It uses semantics from existing collection vocabularies and linked data vocabularies to establish connections between the collection media objects and the events, people, locations and concepts that are depicted or associated with those objects.


N-Screen :
N-Screen demonstrates how Semantic Web technologies can be used as a tool to connect TV content and the Web through Linked Open Data, as part of the wider trend of TV and Web convergence. By specifying protocols and APIs to support a variety of realistic user scenarios for experiencing future TV, N-Screen offers a novel contribution to the TV media world.


Waisda Crowdsourcing Game for Video Tagging:
Waisda? is a video labelling game. Players watch short video fragments (typically between 1 and 10 minutes long) and add relevant tags to the video at specific moments in time. If a tag matches another player’s tag (perhaps from a previous session for the same video), both players are awarded points. Waisda on GitHub


Dr. Watson – Crowdsourcing Game:
Dr. Watson is an medical image and text annotation game, specifically for designed to attract volunteers with medical or biological background to help annotate microscopic images and medical texts.



CrowdTruth Crowdsourcing Framework for Ground Truth Collection:
The CrowdTruth Framework implements an approach to machine-human computing for collecting annotation data on text, images, sounds and videos. The approach is focussed specifically on collecting gold standard data for training and evaluation of cognitive computing systems. The original framework was inspired by the IBM Watson project. CrowdTruth on GitHub



The Open PHACTS Discovery Platform provides access to a collection of tools and services to question multiple integrated and publicly available data sources to support drug discovery. The Open PHACTS Explorer provides an intuitive and robust interface that allows the user to easily and intuitively query and download the data, with direct links through to the original data source to assess its provenance. The Open PHACTS API allows third-party apps to query the data within the Open PHACTS Discovery Platform, combining it with other data and workflow tools.
