What the Adoption of schema.org Tells About Linked Open Data

Heiko Paulheim
2015 Extended Semantic Web Conference  
schema.org is a common data markup schema, pushed by large search engine providers such as Google, Yahoo!, and Bing.  ...  To date, a few hundred thousand web site providers adopt schema.org annotations embedded in their web pages via Microdata.  ...  This allows for analyzing the conformance to standard, schema, and best practices, as it is has been done in various places for Linked Open Data as well [3, 7] .  ...

deepschema.org: An Ontology for Typing Entities in the Web of Data

Panayiotis Smeros, Amit Gupta, Michele Catasta, Karl Aberer
2017 The Web Conference  
We describe the automated procedure we used for extracting a class hierarchy from Wikidata and analyze the main characteristics of this hierarchy.  ...  We also provide a novel technique for integrating the extracted hierarchy with schema.org, which exploits external dictionary corpora and is based on word embeddings.  ...  In Section 4 we present the methods that we use for integrating Wikidata and schema.org. In Section 5 we describe the implementation and analyze the basic characteristics of the unified ontology.  ...

Employing Search Engine Optimization (SEO) Techniques for Improving the Discovery of Geospatial Resources on the Web

Samy Katumba, Serena Coetzee
2017 ISPRS International Journal of Geo-Information  
Pages marked up with Schema.org were more effectively retrieved than those marked up with Dublin Core. The statistical results were significant in most of the tests performed.  ...  The metadata in one set was marked up with Dublin Core, the other with Schema.org. Analysis of the results shows that Google was more effective than Bing in retrieving the pages.  ...  The number of pages that were retrieved and rank statistics were analyzed to evaluate retrieval effectiveness of the web search engines.  ...

SEMANTICAL ENRICHMENT OF WEB USER INTERFACES IN THE CROWD

2019 IADIS International Journal on WWW/Internet  
We analyze the requirements on structured user interface data and investigate the suitability of Schema.org as a vocabulary to fulfil them.  ...  In addition, most Schema.org tools are limited in terms of the Schema.org classes and properties they offer and do not support the semantical enrichment of web user interfaces.  ...  To find answers to this research questions, this article discusses reasons, why structured user interface data can be helpful and analyzes requirements for structured data.  ...

Dataset or Not? A Study on the Veracity of Semantic Markup for Dataset Pages [chapter]

Tarfah Alrashed, Dimitris Paparas, Omar Benjelloun, Ying Sheng, Natasha Noy
2021 Lecture Notes in Computer Science  
We analyze the veracity of dataset markup for Dataset Search's Web-scale corpus and categorize pages where this markup is not reliable.  ...  In this paper, we analyze the scale of the problem, focusing in particular on whether pages with Schema.org/Dataset markup actually describe datasets.  ...  A page that both describes and analyzes a dataset and provides links to a dataset download is a dataset page.  ...
