It explains how SKOS differs from OWL a more formal system of semantics. Along the way, basic Linked Data Principles are explained. Includes links to references and demos, which explain the benefits of using SKOS as well as areas that need to be developed further.

It introduces the key concepts related to metadata standards and Linked Data and how they can be practically applied to existing metadata. Chapters are dedicated to modeling, cleaning, reconciling, enriching, and publishing one's data.

]]> Introducing SKOS https://ld4pe.dublincore.org/learning_resource/introducing-skos/ Fri, 05 May 2017 06:59:13 +0000 https://ld4pe.dublincore.org/learning_resource/introducing-skos/ SKOS (Simple Knowledge Organization System) is a model for expressing knowledge organization systems in a machine-understandable way, within the framework of the Semantic Web. The SKOS Core Vocabulary is an RDF application. SKOS Core provides a model for expressing the basic structure and content of concept schemes, including thesauri, classification schemes, subject heading lists, taxonomies, terminologies, glossaries, and other types of controlled vocabulary. This article provides some examples for using SKOS and discusses the general principles of building such knowledge bases.

]]> RDFS for Hierarchy and Subsumption https://ld4pe.dublincore.org/learning_resource/rdfs-for-hierarchy-and-subsumption/ Sun, 02 Apr 2017 06:55:49 +0000 https://ld4pe.dublincore.org/learning_resource/rdfs-for-hierarchy-and-subsumption/ This PowerPoint presentation explains the role which concepts from thesauri and taxonomies play in Linked Data (especially as they relate to SKOS). It briefly discusses ontologies in general before moving on to RDF Schema. Examples are given of how to defines classes of resources and the relations that connect them using RDFS. Focuses on defining hierarchical relations in support of inference (i.e., formally stating that membership in a narrower class automatically implies membership in a broader class).

]]> What SKOS-XL adds to SKOS https://ld4pe.dublincore.org/learning_resource/what-skos-xl-adds-to-skos/ Tue, 10 Jan 2017 06:45:33 +0000 https://ld4pe.dublincore.org/learning_resource/what-skos-xl-adds-to-skos/ In this blog post, the author describes the differences between SKOS and SKOS-XL. Includes a brief example (in Turtle syntax) of a SKOS-XL representation with extra properties adding metadata to some of the labels describing entities in a dataset. He explains that this would not be possible in regular SKOS, because there labels are considered strings (or, sometimes, "lexical entities") and are not allowed to posses such properties of their own.

]]> Pulling SKOS "prefLabel" and "altLabel" Values Out of DBpedia https://ld4pe.dublincore.org/learning_resource/pulling-skos-preflabel-and-altlabel-values-out-of-dbpedia/ Tue, 10 Jan 2017 06:45:33 +0000 https://ld4pe.dublincore.org/learning_resource/pulling-skos-preflabel-and-altlabel-values-out-of-dbpedia/ In this blog post, the author proposes that DBpedia may be the best source of reusable URIs when one is seeking to describe entities in Linked Open Data. He shares a script for a SPARQL query that selects preferred and alternative labels for a group of DBpedia entries at once. Taking this a step further and adding a few SKOS properties to the mix, a single query can pull data from DBpedia to populate a SKOS-based thesaurus with preferred and alternative labels.

]]> From SKOS over SKOS-XL to Custom Ontologies https://ld4pe.dublincore.org/learning_resource/from-skos-over-skos-xl-to-custom-ontologies/ Mon, 28 Nov 2016 05:58:41 +0000 https://ld4pe.dublincore.org/learning_resource/from-skos-over-skos-xl-to-custom-ontologies/ This webinar explains how taxonomy management based on Simple Knowledge Organization System (SKOS) can be extended with SKOS-XL, based on W3C's Semantic Web standards. See how SKOS-XL can be combined with ontologies like the Financial Industry Business Ontology (FIBO). After covering these core concepts, the speaker moves on to a demonstration of the Pool Party Semantic Suite's SKOS-XL editor.

PoolParty's built in reference corpus analysis based on powerful text mining helps to continuously extend taxonomies. Its built-in co-occurence analysis supports taxonomists with the identification of candidate concepts.

PoolParty Semantic Integrator can be used for deep data analytics tasks and semantic search. See how this can be integrated with various graph databases and search engines.

]]> AGDISTIS – Graph-Based Disambiguation of Named Entities using Linked Data https://ld4pe.dublincore.org/learning_resource/agdistis-graph-based-disambiguation-of-named-entities-using-linked-data/ Sat, 16 Jan 2016 13:43:29 +0000 https://ld4pe.dublincore.org/learning_resource/agdistis-graph-based-disambiguation-of-named-entities-using-linked-data/ The ongoing transition from the current Web of unstructured data to the Web of Data yet requires scalable and accurate approaches for the extraction of structured data in RDF from these websites. One of the key steps towards extracting RDF from text is the disambiguation of named entities. While several approaches aim to tackle this problem, they still achieve poor accuracy. We address this drawback by presenting AGDIS-TIS, a novel knowledge-base-agnostic approach for named entity disambiguation.

The intent is to create a ready reference that will be useful for both the beginner and the experienced practitioner alike. It is also intended to grow and mature in line with the practitioner community. NOTE: This is a book-length resource and covers a wide range of different areas from the design of Web-scale identifiers to application development patterns.

]]> 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.
