How Not to Do Open Publications LOD

http://lod.openaire.eu/vocab is buggy as hell.

Mentions classes Publication , Dataset , FundingStream that have no definition
Strange local mappings, e.g. class DataSource that is mapped to prov:Entity without any description or explanation of this mapping; foaf:lastName is given local label "Secondnames"
Reuses and redefines external properties e.g. like http://purl.org/cerif/frapo/hasCallIdentifier without reproducing the description e.g. "A data property specifying the identifying number of a call for applications issued by a funding agency."
Many recursive links rdfs:isDefinedBy
Dumbs-down CERIF links to direct properties (e.g. http://lod.openaire.eu/vocab/funder) instead of using flexible links (eg the Proj_Org class)
Strange labels such as Openairecompatibility, oamanDatePublications.

How to use Google Sheets to Manage Wikidata Coreferencing

A previous post How to Add Museum IDs to Wikidata explained how to use SPARQL to find missing data on Wikidata (Getty Museum IDs), how to create such values (from museum webpage URLs) and how to format them properly for QuickStatements.

Here I explain how to use Google sheets to manage a more advanced task. The sheet AAT-Wikidata matches about 3k AAT concepts to Wikipedia, WordNet30 and BabelNet (it restored an old mapping to Wordnet, retrieved it from BabelNet, mapped to Wikipedia).

For each row, it uses the following Google sheet formula (column C) to query the Wikipedia API and get the corresponding Wikidata ID (wikibase_item); split on two lines for readability:

=ImportXml(concat("https://en.wikipedia.o

Linked Research is a movement to publish articles in HTML, with embedded semantic data that would allow not just citations but much deeper interactions. Sarven Capadisli is at the forefront of this, and people like Tim Berners-Lee and Soren Auer support it fully. I believe this is the future of scholarly publishing.

see http://csarven.ca/archives/articles for relevant articles
https://dokie.li is a template and a set of CSS that produces native HTML, LNCS and ACM styles. It also includes nice interactive tools (eg comments, citations, Sparklines) but is not yet a fully-fledge editor

The best way to write research articles is, of course, plain text.
