SKOS in Two Parts: Generic Tools and Methods for SKOS-based Concept Schemes

The series is in partnership with AIMS: Agricultural Information Management Standards

Webinar 1 Date: Wednesday, 16 March 2016, 10:00am-11:15am EDT (UTC 14:00 - World Clock: http://bit.ly/webinar-neubert)
Webinar 2 Date: Wednesday, 6 April 2016, 10:00am-11:15am EDT (UTC 14:00 - World Clock: http://bit.ly/webinar-suominen)

Series Abstract:In the past seven years, SKOS has become a widely recognized and used common interchange format for thesauri, classifications, and other types of vocabularies. This has opened a huge opportunity for the development of generic tools and methods that should apply to all vocabularies that can be expressed in SKOS. While expensive, proprietary or custom-developed solutions aimed at one particular thesaurus or classification have been dominant, now more and more open source tools are being created to deal with various aspects of vocabulary management. In this series of two webinars with Joachim Neubert (ZBW Leibniz Information Centre for Economics, Germany) and Osma Suominen (National Library of Finland), we start on 16 March 2016 with Webinar 1 by examining skos-history, a method and toolset to nail down changes in a vocabulary. We follow with Webinar 2 on 6 April 2016 focusing on Skosmos, a full-fledged web application for publishing SKOS vocabularies.

Webinar 1: Change Tracking in Knowledge Organization Systems with skos-history

With Joachim Neubert (ZBW Leibniz Information Centre for Economics, Germany) and Osma Suominen (National Library of Finland)

Webinar 1 Abstract: When a new version of a vocabulary is published, users want to know "What’s new?" and "What has changed?" Vocabulary managers had differing strategies to answer these questions—relying on internal logs of the vocabulary management system or the intellectual collection of changes deemed relevant. These methods generally are not available to third parties using a vocabulary, or for example are trying to keep vocabulary mappings up to date.

Having vocabularies published in SKOS as RDF triples has changed this situation: Vocabularies can be compared algorithmically, and deltas between versions can be computed. This data can be loaded into a version store, and evaluated by SPARQL queries. Therefore, the published versions alone are sufficient to get the differences.

The webinar will explain how you can create a version store, how skos-history interlinks versions and deltas, and how queries can get a grip on added or removed concepts, on changed notations, or on merges and splits of concepts. We will show how aggregated change information about a concept scheme can be obtained, and how the complete change history of a single concept across multiple versions can be traced. Finally, you will learn how you can adapt skos-history queries to the features of a particular concept scheme in which you are interested.

Skill level: Intermediate. A working knowledge of SKOS and a basic knowledge of triple stores and SPARQL queries are presumed.

Webinar 2: Publishing SKOS concept schemes with Skosmos

With Osma Suominen (National Library of Finland)

Webinar 2 Abstract: With more and more thesauri, classifications and other knowledge organization systems being published as Linked Data using SKOS, the question arises how best to make them available on the web. While just publishing the Linked Data triples is possible using a number of RDF publishing tools, those tools are not very well suited for SKOS data, because they cannot support term-based searching and lookup.

This webinar presents Skosmos, an open source web-based SKOS vocabulary browser that uses a SPARQL endpoint as its back-end. It can be used by e.g. libraries and archives as a publishing platform for controlled vocabularies such as thesauri, lightweight ontologies, classifications and authority files. The Finnish national thesaurus and ontology service Finto, operated by the National Library of Finland, is built using Skosmos.

Skosmos provides a multilingual user interface for browsing and searching the data and for visualizing concept hierarchies. The user interface has been developed by analyzing the results of repeated usability tests. All of the SKOS data is made available as Linked Data. A developer-friendly REST API is also available providing access for using vocabularies in other applications such as annotation systems.

We will describe what kind of infrastructure is necessary for Skosmos and how to set it up for your own SKOS data. We will also present examples where Skosmos is being used around the world.

Skill level: Intermediate. A working knowledge of SKOS and a basic knowledge of triple stores and SPARQL queries are presumed.

Linked Data Fragments: Querying multiple Linked Data sources on the Web

Webinar Date: Wednesday, 17 February 2016, 10:00am-11:15am EST (UTC 15:00 - World Clock: http://bit.ly/Webinar-Verborgh)

Abstract: The dream of Linked Data: if we just get our data online, the promised Semantic Web will eventually rise. Everybody will be able to query our data with minimal effort. We will be able to integrate data from multiple sources on the fly. Everything will just work and data will flow freely ever after.

Well, that hasn't really happen yet.

Even though we published billions of triples on the Web, there are few places that reliably let us execute queries over them. Integration is still very limited. When will our efforts ever pay off?

This webinar introduces you to the Linked Data Fragments family of technologies, which take a much more pragmatic view on the Web of Data. Whereas one of the main problems with the Semantic Web is currently the high publication cost of data (with unknown return), Linked Data Fragments proposes to shift the complexity of querying from the server to the client. This makes publishing Linked Data affordable, and realistic on the Web.

You might have heard about Linked Data Fragments already, or you might just be curious about scalable Linked Data publishing or querying on the Web. This webinar by Ruben Verborgh, creator and lead researcher of Linked Data fragments, is the perfect introduction to understand the important principles and vast potential of what this technology has to offer.

In this webinar, you'll see:

  • what Linked Data Fragments is and what it means for you
  • how to execute queries over multiple Linked Data sources live on the Web
  • how to publish your Linked Data at low cost, so others can query it

Minimum Participant Experience Level: Fundamental awareness of Linked Data required; novice level experience recommended

Creating Content Intelligence: Harmonized Taxonomy & Metadata in the Enterprise Context

Webinar Date: Wednesday, 27 January 2016, 10:00am-11:15am EST (UTC 15:00 - World Clock: http://bit.ly/webinar-lemieux)

Abstract: Many organizations have content dispersed across multiple independent repositories, often with a real lack of metadata consistency. The attention given to enterprise data is often not extended to unstructured content, widening the gap between the two worlds and making it near impossible to provide accurate business intelligence, good user experience, or even basic findability.

How do you bring all those disparate efforts together to create content intelligence across the organization? This webinar will describe the benefits and challenges in developing metadata and taxonomy across multiple functional areas, creating a unified Enterprise Content Architecture (ECA).

Hear about real enterprise metadata & taxonomy harmonization projects in different contexts, including a greeting card company, a media company, an automotive manufacturer and a consumer food manufacturer. See how they worked to harmonize across a number of diverse systems that supported multiple functions, from creative processes to manufacturing to reporting.

In this webinar, you will learn:

  • how the concept of Enterprise Content Architecture unifies multiple disciplines, including information management, data management and content strategy;
  • the difference and similarities between master data and business metadata;
  • how enterprise-level metadata and taxonomy helps drive semantic interoperability and improve business processes;
  • how taxonomy can be harmonized across diverse systems and provided as a service; and
  • how to build support and governance for enterprise-level attention to taxonomy and metadata from within a project

Participant Experience Level: Basic familiarity with taxonomy and metadata assumed.

Schema.org in Two Parts: From Use to Extension

Series Abstract: When it was first introduced in 2011 Schema.org was seen by many as a grab, by Google and other search engines, for the semantic web landscape, or as something only of interest to the SEO community wanting their products displayed more prominently in search results. It was therefore somewhat of a surprise to the library community when, less than a year later, the global library cooperative OCLC introduced Schema.org structured data markup into the pages for the 300 million plus resources on Worldcat.org.

Things have changed significantly since those early days. Schema.org structured data is now published on over 10 million web domains; the vocabulary has expanded to include over 600 Types and nearly 1,000 Properties; it’s core capability for describing bibliographic resources has been greatly extended. There is now a specific bibliographic extension — bib.schema.org and, Schema.org implementations and discussions are becoming common in the library community.

Join Independent consultant Richard Wallis, former Technology Evangelist for OCLC, currently working with Google on Schema.org, for this two part, in-depth mini-series look at Schema.org, its use, and extension in the bibliographic domain and beyond.

Part 1: Fit For a Bibliographic Purpose

Date/Time: Wednesday, 18 November 2015 at 10:00am-11:15am EST (UTC 15:00:00 - World Clock: http://bit.ly/Webinar-1_Wallis)

Abstract: In this first webinar in the series, Independent Consultant, Richard Wallis, traces the history of the Schema.org vocabulary, plus its applicability to the bibliographic domain. He will share the background to, and activities of, the Schema Bib Extend W3C Community Group he chairs; why it was set up; how it approached the creation of bibliographic extension proposals; and how those proposals were shaped. He will then review the current status of the vocabulary and the recent introduction of the bib.schema.org and auto.schema.org extensions. Although Richard will be using bibliographic examples, the content of this webinar will be of interest and relevance to those in other domains, and/or considering other extensions.

Part 2: Extending Potential and Possibilities

Date/Time: Wednesday, 2 December 2015, 10:00am-11:15am EST (UTC 15:00:00 - World Clock: http://bit.ly/Webinar-2_Wallis)

Abstract: In this second more technical webinar in the series, Independent Consultant, Richard Wallis, explains the Schema.org extension mechanism, for external and reviewed/hosted extensions, and their relationship to the core Schema.org vocabulary. He will take an in-depth look at, demonstrate, and share experiences in designing, and creating a potential extension to the vocabulary. He will step through the process of creating the required vocabulary definition and examples files on a local system using a few simple tools then sharing them on a publicly visible temporary cloud instance before proposing to the Schema.org group.

Implementing Linked Data in Low-Resource Conditions

Webinar Date: Wednesday, 17 June 2015 9 September 2015, 10:00am-11:15am EDT (UTC 14:00 - World Clock: http://bit.ly/webinar-keiser)

Abstract: Opening up and linking data is becoming a priority for many data producers because of institutional requirements, or to consume data in newer applications, or simply to keep pace with current development. Since 2014, this priority has gaining momentum with the Global Open Data in Agriculture and Nutrition initiative (GODAN). However, typical small and medium-size institutions have to deal with constrained resources, which often hamper their possibilities for making their data publicly available. This webinar will be of interest to any institution seeking ways to publish and curate data in the Linked Data World.

Keizer and Caracciolo will provide an overview of bottlenecks that institutions typically face when entering the world of open and linked data, and will provide recommendations on how to proceed. They will also discuss the use of standard and linked vocabularies to produce linked data, especially in the area of agriculture. They will describe AGRISAs, a web-based resource linking agricultural datasets as an example of linked data application resulting from the collaboration of small institutions. They will also mention AgriDrupal, a Drupal distribution that supports the production and consumption of linked datasets.

OpenAIRE Guidelines: Promoting Repositories Interoperability and Supporting Open Access Funder Mandates

Webinar Date: Wednesday, 1 July 2015, 10:00am-11:15am EDT (UTC 14:00 - World Clock: http://bit.ly/pprincipe)

Abstract: The OpenAIRE Guidelines for Data Source Managers provide recommendations and best practices for encoding of bibliographic information in OAI metadata. They have adopted established standards for different classes of content providers: (1) Dublin Core for textual publications in institutional and thematic repositories; (2) DataCite Metadata Kernel for research data repositories; and (3) CERIF-XML for Current Research Information Systems.

The principle of these guidelines is to improve interoperability of bibliographic information exchange between repositories, e-journals, CRIS and research infrastructures. They are a means to help content providers to comply with funders Open Access policies, e.g. the European Commission Open Access mandate in Horizon2020, and to standardize the syntax and semantics of funder/project information, open access status, links between publications and datasets. The presenters will provide an overview of the guidelines, implementation support in major platforms and tools for validation.

Approaches to Making Dynamic Data Citable: Recommendations of the RDA Working Group

Webinar Date: Wednesday, 8 April 2015, 10:00am-11:15am EDT (UTC 14:00 - World Clock: http://bit.ly/Webinar-Andreas_Rauber)

Abstract: Being able to reliably and efficiently identify entire or subsets of data in large and dynamically growing or changing datasets constitutes a significant challenge for a range of research domains. In order to repeat an earlier study, to apply data from an earlier study to a new model, we need to be able to precisely identify the very subset of data used. While verbal descriptions of how the subset was created (e.g. by providing selected attribute ranges and time intervals) are hardly precise enough and do not support automated handling, keeping redundant copies of the data in question does not scale up to the big data settings encountered in many disciplines today. Furthermore, we need to be able to handle situations where new data gets added or existing data gets corrected or otherwise modified over time. Conventional approaches, such as assigning persistent identifiers to entire data sets or individual subsets or data items, are thus not sufficient.

In this webinar, Andreas Rauber will review the challenges identified above and discuss solutions that are currently elaborated within the context of the working group of the Research Data Alliance (RDA) on Data Citation: Making Dynamic Data Citeable. The approach is based on versioned and time-stamped data sources, with persistent identifiers being assigned to the time-stamped queries/expressions that are used for creating the subset of data. We will further review results from the first pilots evaluating the approach.

Webinar Date: Wednesday, 4 March 2015, 10:00am-11:15am EST (UTC 15:00 - World Clock: http://bit.ly/DCMI-Webinar-Stellato)

Abstract: VocBench is a web-based platform for the collaborative maintenance of multilingual thesauri. VocBench is an open source project, developed in the context of a collaboration between the Food and Agricultural Organization of the UN (FAO) and the University of Rome Tor Vergata. VocBench is currently used for the maintenance of AGROVOC, EUROVOC, GEMET, the thesaurus of the Italian Senate, the Unified Astronomy Thesaurus of Harvard University, as well as other thesauri.

VocBench has a strong focus on collaboration, supported by workflow management for content validation and publication. Dedicated user roles provide a clean separation of competencies, addressing different specificities ranging from management aspects to vertical competencies in content editing, such as conceptualization versus terminology editing. Extensive support for scheme management allows editors to fully exploit the possibilities of the SKOS model, as well as to fulfill its integrity constraints.

Since version 2, VocBench is open source software, open to a large community of users and institutions supporting its development with their feedback and ideas. During the webinar we will demonstrate the main features of VocBench from the point of view of users and system administrators, and explain in what way you may join the project.

The Libhub Initiative: Increasing the Web Visibility of Libraries

Webinar Date: Wednesday, 7 January, 2015, 10:00am-11:15am EST (UTC 15:00 - World Clock: http://bit.ly/DCMI-Webinar-Miller)

Abstract: As a founding sponsor, Zepheira's introduction of the Libhub Initiative creates an industry-wide focus on the collective visibility of libraries and their resources on the Web. Libraries and memory organizations have rich content and resources that the Web can not see or use. The Libhub Initiative aims to find common ground for libraries, providers, and partners to publish and use data with non-proprietary, web standards. Libraries can then communicate in a way Web applications understand and Web users can see through the use of enabling technology like Linked Data and shared vocabularies such as schema.org and BIBFRAME. The Libhub Initiative uniquely prioritizes the linking of these newly exposed library resources to each other and to other resources across the Web, a critical requirement of increased Web visibility.

In this webinar, Eric will talk about the transition libraries must make to achieve Web visibility, explain recent trends that support these efforts, and introduce the Libhub Initiative — an active exploration of what can happen when libraries begin to speak the language of the Web.

The Learning Resource Metadata Initiative, describing learning resources with schema.org, and more?

Webinar Date: Wednesday, 19 November, 2014, 10:00am-11:15am EST (UTC 15:00 -- World Clock: http://bit.ly/1pKiCUj)

Abstract: The Learning Resource Metadata Initiative (LRMI) is a collaborative initiative that aims to make it easier for teachers and learners to find educational materials through major search engines and specialized resource discovery services. The approach taken by LRMI is to extend the schema.org ontology so that educationally significant characteristics and relationships can be expressed. In this webinar, Phil Barker and Lorna M. Campbell of Cetis will introduce schema.org and present the background to LRMI, its aims and objectives, and who is involved in achieving them. The webinar will outline the technical aspects of the LRMI specification, describe some example implementations and demonstrate how the discoverability of learning resources may be enhanced. Phil and Lorna will present the latest developments in LRMI implementation, drawing on an analysis of its use by a range of open educational resource repositories and aggregators, and will report on the potential of LRMI to enhance education search and discovery services. Whereas the development of LRMI has been inspired by schema.org, the webinar will also include discussion of whether LRMI has applications beyond those of schema.org.

How to pick the low hanging fruits of Linked Data

Webinar Date: Wednesday, 21 May, 2014, 10:00am EDT (World Clock: 14:00 UTC http://bit.ly/1qLSeq1)

Abstract: The concept of Linked Data has gained momentum over the past few years, but the understanding and the application of its principles often remain problematic. This webinar offers a short critical introduction to Linked Data by positioning this approach within the global evolution of data modeling, allowing an understanding of the advantages but also of the limits of RDF. After this conceptual introduction, the fundamental importance of data quality in the context of Linked Data is underlined by applying data profiling techniques with the help of OpenRefine. Methods and tools for metadata reconciliation and enrichment, such as Named-Entity Recognition (NER), are illustrated with the help of the same software. This webinar will refer to case-studies with real-life data which can be re-used by participants to continue to explore OpenRefine at their own pace after the webinar. The case-studies have been developed in the context of the handbook "Linked Data for Libraries, Archives and Museums", which will be published by Facet Publishing in June 2014.
