Facilitating Web Science Collaboration through Semantic Markup
The document discusses the development of web observatories aimed at enhancing collaboration among web science researchers by sharing and reusing data and tools. It emphasizes the use of schema.org for structured data markup to improve the discoverability of various datasets and tools within these observatories. Future work includes extending the schema vocabulary and building better integration tools for enhanced metadata usage in scientific communities.

Introduction 6 • Web Scienceinvolves using and producing large amounts of heterogeneous data about and from the web" " • As we (Web Science researchers) strive to collaborate and work together, we must find ways to share, link and reuse each other’s data and tools." " • To do this, we are striving to build “Web Observatories” – a common infrastructure for enhancing this sharing, and to extend it to also include tools, research project results(papers & experiments), etc." Tiropanis,T., Hall,W., Shadbolt, N., DeRoure, D., Contractor, N. and Hendler, J., TheWeb Science Observatory, IEEE Intelligent Systems, March/April, 2013.

Schema.org 6 • An initiativelaunched by the leading search engine providers to create and support a common set of schemas for structured data markup on Web pages. • These vocabularies enable the metadata to be more machine readable, allowing for better search, discover and display this information

- 23. Conclusions Science Data Observatory SocialSpaces Observatory • Integrating data on the Web, in general, is growing • Schema.org is a data embedding model showing great success • Schema.org/Dataset became official April 2013 • Search Engine tools are increasingly making used of embedded markup • Web Observatory extension aimed at use in (Web) scientific community • Also being used by AGU and DCO scientific
- 24. Future Work Science DataObservatory Social Spaces Observatory • Further extend the vocabulary to fit more web observatories • Subcommunities can extend terminologies • Build better tools to use and embed schema.org vocabulary into web observatories • Integrate into “telescope” toolbox • Build tools to make use of schema.org WO metadata (search engines, crawlers, etc) • Google Domain Search underway
