RDFa for html authors

Vocabulary


  • RDF : Data model for metadata


  • XML


  • Ontology


  • JSON


  • Knowledge graph

  • JATS: Journal Article Tag Suite Source - xml for scientif articles / publications

‣ Semantic Web and Science #

Softwares

‣ ‣ Example: Life Sciences#

Note

Good example with overview of softwares etc … To read!

‣ ‣ Example: SciData#

SciData is a data model for scientific data (JSON-LD implementation) that provides a ontologically defined framework for organizing both the data and metadata from scientific experiments, calculations, and theories

From RAW HTML To Metadata#

  • [Simple HTML Ontology Extensions](Simple HTML Ontology Extensions)

to check: Microformat

‣ Microdata #

Sometimes, it is desirable to annotate content with specific machine-readable labels, e.g. to allow generic scripts to provide services that are customized to the page, or to enable content from a variety of cooperating authors to be processed by a single script in a consistent manner. For this purpose, authors can use the microdata features described in this section. Microdata allows nested groups of name-value pairs to be added to documents, in parallel with the existing content.

Note

Is it semantic ? Good first step

Compatible with schema.org ?

  • Info

  • itemscope

  • itemtype

  • itemid

  • itemprop

  • itemref

  • datetime

I don’t really use html tags (ie it is the point of JupyterBook to releive you from using use by building html from markdown files). However there is a few exception to this rule:

To explain complicated words I use span tags.

  • Ontology

Note

Should I start putting span divs with microdata tags to be able to make my data linkable ?

Ask Alessio

‣ ‣ Example #

<div itemscope itemtype ="https://schema.org/Movie">
  <h1 itemprop="name">Avatar</h1>
  <div itemprop="director" itemscope itemtype="https://schema.org/Person">
  Director: <span itemprop="name">James Cameron</span> (born <span itemprop="birthDate">August 16, 1954</span>)
  </div>
  <span itemprop="genre">Science fiction</span>
  <a href="../movies/avatar-theatrical-trailer.html" itemprop="trailer">Trailer</a>
</div>

Microdata vocabularies do not provide the semantics, or meaning of an item

use vocabularies available on the web -> Schema.org

‣ Scientific Articles Metadata #

‣ ‣ JATS #

  • JATS: Journal Article Tag Suite Source - xml for scientif articles / publications

From Metadata in HTML to RDF#

<head>
<title>My Document</title>
<link rel="meta" type="application/rdf+xml" href="meta.rdf"/>
</head>

Ontologies#

[Munir and Anjum, 2018]

‣ Definition #

\( {\displaystyle i=\langle C_{i},R_{i},I_{i},T_{i},V_{i}\rangle } \)

  • C is the set of classes,

  • R is the set of relations,

  • I is the set of individuals,

  • T is the set of data types,

  • V is the set of values,

Ontologies come in different serialisations, formalisms, and variants For example, their are a 9 different release files associated with an ontology.

I would like to:

  • Article - from taxonomy to ontology

    • The different foler / subfolder

  • Object properties can be given sense by adding **Characteristic

    • isMarkdown

    • is Folder

Note

Relation from ensemble theory

  • Fuctional

  • Transitive

  • Symetric

  • Reflexive

‣ Online tutorials #

‣ Ontology matching #

[Otero-Cerdeira et al., 2015]

To do#

To do

  • Think about what is important in the project

    • Define specific type of content within websiteand allocate proper description

    • look in Schema.org for specific tag

  • embed RDF into web-page

JSON

To do

  • Check how to implement into JupyterBook

    • Github issue ?

‣ What do I need to do #

  • Have a look at the preexisting ontologies (?) and select the one that are of interest

  • Think about what is important and need highlighting

Knowledge graphs#

OU Open knowledge graph

Other examples

  • from Angelo - This data is extracted from knowledge graph. (is it ?) - How?

Question

  • Should I embed my own work (thesis) there ?

  • Better to generate my own parent website to create a publication plateform linking different work
