Distills results taken from large datasets so that visualizations are human-friendly. – Linked Data for Professional Education https://ld4pe.dublincore.org Learning resources tagged by competency Thu, 19 Nov 2020 14:45:03 +0000 en-US hourly 1 https://wordpress.org/?v=4.9.16 Visualising Related Entries in Wikipedia Using Gephi https://ld4pe.dublincore.org/learning_resource/visualising-related-entries-in-wikipedia-using-gephi/ Sat, 14 Jan 2017 06:46:01 +0000 https://ld4pe.dublincore.org/learning_resource/visualising-related-entries-in-wikipedia-using-gephi/ In this blog post, the author shares how to use the Gephi visualization tool's Semantic Web Import plugin to retrieve data from DBpedia and turn it into a network visualization. Includes a brief discussion of how SPARQL queries are formed, but the post is more appropriate for users who already have some familiarity.

In particular, it gives an overview of current visualization tools and techniques, looking at semantic browsers and applications for presenting the data to the end user. Also includes approaches for Linked Data analysis, describing how available data can be synthesized and processed in order to draw conclusions. Contains a number of practical examples with available tools as well as an extensive demo based on analyzing, visualizing and searching data from the music domain.

]]> Knowledge Engineering and the Web https://ld4pe.dublincore.org/learning_resource/knowledge-engineering-and-the-web/ Tue, 10 Nov 2015 05:13:00 +0000 https://ld4pe.dublincore.org/learning_resource/knowledge-engineering-and-the-web/ The lecturer asserts that the Web can be viewed as a vehicle for knowledge democracy. Several technologies have been developed to support knowledge transfer via the Web, including languages like RDF, OWL and SKOS. He discusses the effectiveness of these technologies, as well as methods and techniques that can be used for practical Web-based knowledge engineering. He illustrates this with application examples in the domain of digital heritage collections.

It contains a practical example of how to use taxonomies to index and classify unstructured data (in this case, notes related to medical risks) and then model them in AllegroGraph. It then goes further to show how to make this model even better by using Linked Open Data to connect to other datasets, such as SNOMED and MESH.

It gives an overview of current visualization tools and techniques, looking at semantic browsers and applications for presenting the data to the end user. Also described are existing search options, based on a mix of semantic information and text processing. Finally, the presentation concludes with approaches for Linked Data analysis, describing how available data can be synthesized and processed in order to draw conclusions. NOTE: These slides represent material from several lessons that comprised a larger "module" of the EUCLID Project. As such, they cover a wider range of topics than most resources.
