15 Linked Open Data Data on a Solid Stack Universal network of units with explicit meaning to bridge semantic gaps (string of numbers is a price) Semantic Web architecture (e.g. Resource Description Framework for standardized meaning representation) Enable or facilitate computers and people to work better in cooperation 30 percent of HTML pages contain structured data <div itemscope itemtype=" <div itemprop="name"><strong>easy Graphics Framework</strong></div> </div> 15
16 Linked Open Data Representing Knowledge Subject Predicate Object Conceptualization/model = explicit, machine understandable, consensus Vocabulary = describes and represents an area of concern Classifies terms that can be used in a particular application Characterizes entities Schema.org vocabulary allows search engines to recognize information easier and more precisely 16
17 Linked Open Data Embedded Structured Data Embed structured data with explicit semantic annoations in HTML documents Microformats misuse <div class= vcard RDFa reuse <p vocab=..foaf typeof= Person ><span property= name > HTML5 microdata annoate DOM with scoped name/value pairs from custom vocabularies HTML attributes: itemscope, vocabularies: person, event, 17
18 Linked Open Data One model, various serializations (N-triples) < "Eric Miller". 18
19 Linked Open Data One model, various serializations (JSON-LD) { "@context": { "contact": " " [...] }, "@id": " "@type": "contact:person", "contact:fullname": "Eric Miller" [...]} JSON-LD: non intrusive, e.g. link from HTML file: <link href="jsonld.js" rel="alternate" type="application/ld+json" /> 19

36 IN 21 Presentation Summit Meeting: Search meets Terminology Felix Sasaki, DFKI / W3C Fellow, Berlin Christian Lieske, SAP, St. Leon-Rot Introduction The days in which major search engines worked on nothing but strings are long gone. In a similar vein, the Web has evolved from collections of linked Web pages to a myriad of data lakes one can tap into. Meta data annotation and processing concepts related amongst others to the Semantic Web are the backbone of these developments. Interesting questions for today s tech doc community are amongst others: 1. Which role can terminological assets play in today s Web especially in the context of search? 2. How much synergy does already exist between terminology-related tools and resources and Search Engine Optimization (SEO) based on meta data, and markup? Today s Web Content in terms of Relationships and Search Today, the term Semantic Web is used less and less. Instead, the term Linked Data is used. The rationale behind is the following: The first Semantic Web technologies were made available more than 15 years ago. At that time, the core vision of the Semantic Web was automatic inferencing of new knowledge. Example: If A is composed of B, then one can infer that B is a part of A. This vision hardly materialized beyond simple examples like the aforementioned one. Accordingly, the Semantic Web lacked from adoption. Nevertheless, the Semantic Web had a huge impact: One key aspect of the Semantic Web however has found broad adoption: The Semantic Web proposes to have a globally unique identifier (GUID) for anything, and to provide GUIDs even for relations between concepts. Over time, a powerful ensemble of technologies was developed. It encompasses 1. The Resource Description Format (RDF) to create linked data 2. RDF Schema / the Ontology Web Language (OWL) to create linked data vocabularies of different formal complexity 3. The SPARQL family of specifications for queries Furthermore, a large amount of linked data vocabularies has been created: Friend-of-a-friend (FOAF) for persons and their relations
37 Dublin Core for general metadata The Basic Geo Vocabulary for geographical information The Linked Open Vocabularies (LOV) site at maintains an overview of vocabularies. Finally, several syntaxes/serialization formats like RDF/XML or RDFa have been developed (e.g. for processing in various existing workflows). Taken together these Semantic Web concepts and technologies have laid the foundation for the Linked Data movement that is currently revolutionizing the World Wide Web. The base idea: put interesting data entities (e.g. facts) on the Web by identifying them via a GUID. Then, use Semantic Web technologies to create mashups of these entities, and to create powerful search applications. Schema.org as Facilitator In 2011, big search engine providers realized how to benefit from Linked Data, and how that they could assist in lowering the entry barrier for to the world of Linked Data. They adopted the key concepts of the Linked Data technology stack and provided simple mechanisms (markup and vocabularies) to encode (linked) information in Web pages. The outcome was Schema.org, an effort to bring the idea of linked and structured information to the Web at large. The search engine providers understood that Schema.org could only have broad adoption if ideas around GUIDs and vocabularies were not provided by a closed club. Thus, dedicated Schema.org Community Group was formed within the World Wide Web Consortium (W3C) in 2015 to provide an open and transparent forum. The basic ideas of Schema.org are: 1. Provide a way to identify uniquely concepts and relations via Uniform Resource Identifiers (URIs). Examples: The concept (in the terminology of Schema.org types") of a Person is identified via The parent of a person is identified via the relation (in the terminology of Schema.org properties ) There are galleries of examples for widely used Schema.org types, see e.g Provide simple means to embed the aforementioned information into Web content. 3. Use just one vocabulary for the Schema.org definitions. This is a key difference to Semantic Web and Linked Data in general: Vocabularies like FOAF or
38 Dublin Core are maintained independently. The benefit is flexibility; the disadvantage is uncertainty for the user how the vocabularies work together. As of today, according to the Schema.org web site, more than 10 million sites use Schema.org markup to encode Linked Data information without requiring in-depth knowledge of the complex, previously described Semantic Web/Linked Data technology stack. The coverage of domains differs per type: Markup for persons appears on more than 1 million Web site domains. Markup for news article appears in less than domains. Markup for technical articles appears in less than 1000 domains. Terminology as Additional Player Schema.org adheres to the terminology principle of concept orientation. One concept, e.g. a product, has exactly one unique Schema.org identifier. Thus, terminological assets can enter the world of Linked Data. This will be exemplified with the following a scenario: A Chinese technician familiar with Chinese terminology in his field of expertise is looking for product offerings related to 图形提供商, and searches for it on the Web. Since the Web-based user assistance is only available in English and German, the technician does not become aware of a corresponding offering Easy Graphics Framework. The vendor thus may lose a potential sales opportunity. Schema.org could help to overcome this limitation if the vendor s terminological knowledge would also be available in Chinese. Amongst the data categories of the corresponding terminological database, is of course one for a standard is_translation_of relationship. In Schema.org, this relationship is used to realize cross-lingual search that could make the user aware of the vendor s offering. Scenario: Cross-lingual Search based on Schema.org and Terminology The scenario described above so far cannot be realized in a straightforward way: Schema.org does not include a is_translation_of relation to express that something is a term, or even to express a whole term database entry (see discussions at Nevertheless, the scenario can be realized with Schema.org: It provides a sameas relation and the ability to assign a language to a concept via the inlanguage type. Taken together, the two Schema.org construct, can encode the translation relation between 图形提供商 and Easy Graphics Framework that is needed in the scenario at hand. Example: { "@id": " "schema:inlanguage": "zh",
39 "schema:name": " 图形提供商 ", "schema:sameas": { } } "@id": " "schema:inlanguage": "en", "schema:name": "Easy Graphics Framework" Since TermBase exchange (TBX) is used widely in terminological contexts, a TBX-to-schema.org converter thus can be used to use terminological information to generate Schema.org markup that can facilitate cross-lingual search (e.g. retrieving English content based on a query in Chinese). Discussion Based on Semantic Web concepts and technologies, Schema.org enhances search experience (for users), and success (for Web site administrators). As of today, Schema.org does not yet include everything that is needed to realize all cross-lingual scenarios easily. Since Schema.org is based on feedback, input from the tech doc community could help to change this. Contact: felix.sasaki@dfki.de, christian.lieske@sap.com
