Hyperlink Formation in Social Bookmarking Systems: Who is Who Online?BO TRUE ACTIVITIES SL
Social bookmarking systems attract researchers in information systems and social sciences because they offer an enormous quantity of user-generated annotations that reveal the interests of millions of people. In this paper, we explore a different viewpoint to gain an understanding of the social bookmarking systems.
Using data crawled from a large social tagging system we argue that the prominence of a website, as measured by its status or public recognition, also determines its centrality.
To test this hypothesis we predict the indexes of authority and other measures of centrality via Social Network Analysis. We also use Gephi to visualize the networks, and analyze the structure.
The results discussed in the paper come from a sample of 61,043 taggings that involved 3,668 users and 4,913 bookmarked websites from a specific Social Network Sites, Delicious, on the subject of globalization of agriculture.
We find that mass media companies have a competitive advantage in attracting links and user attention.
In this workshop (Master in Translational Medicine-MSc, University of Barcelona's Faculty of Medicine-Hospital Clínic, 14 March 2018) I summarised the benefits which can be gained from use of social media (specially blogs, Twitter and other socialnetwork sites) to support research activities, and I provided examples of these innovative emerging resources as tools for scientific communication related to translational medicine, as well as discussed their implications for digital scholarship.

"Why the Semantic Web will Never Work" (note the quotes)James Hendler
This talk refutes some criticisms of the semantic web, but also outlines some research challenges we must overcome if we are to ever realize Tim Berners-Lee's original Semantic Web vision.
Presentation at September event for SEMPDX in Portland OR. Covering the latest on structured data markup, Open Graph, Schema.org and data markup for SEO.
API standards, from SOAP to REST to GraphQL, have evolved to meet the needs of API providers and developer consumers. They make APIs "intuitive" by making them predictable. When product designs bump up against the constraints of standards, you can choose to force a fit or, you can break from convention and invest in educating developers about your choices. Through case studies (including Facebook's Open Graph and Slack's workspace apps project), we'll examine the tradeoffs, consequences, and some learnings about how to get your developer community to come along with you.
Facebook Open Graph - The Semantic WalletJonathan Laba
This deck covers how Facebook is becoming a hub for consumer devices, apps and services to connect to each other in a secure manner to share data.
Facebook's allowance for the input and retrieval of structured data based on semantic web principles is positioning them to be the gold standard in the management of a unified digital identity.
This deck covers:
- What Social Means to Developers
- What is the Semantic Web
- Facebook's Evolution into Structured Data
- The Semantic Wallet
- Some Questions

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. This presentation is
about...
• Using Facebook OpenGraph to see how
RDFa is used
• Make a simple comparison with RDFa
standard usage
• introduction to Social Objects, the real “x-
factor” of the Web of Data
• Power to the people or to the Web2.0
platform? Let’s thinking about it
4. To a better understanding, don’t think pages,
think Social Objects in a Giant Global Graph
5. Linked Data

Facebook ecosystem, outside of Facebook.com

10. The Web is more a social
creation, than
a technical one.
Sir Tim Berners Lee - 1999
11. Facebook wants to flood the web with these pieces of
functionality, adding a social skew to each and every site.

12. slide taken from http://www.slideshare.net/Saintsocial/facebook-open-graph-explained
Every action taken through social plugins embedded
throughout the web will flow back to your profile, and
especially to the “Open graph”
13. Facebook Open Graph is an attempt to map all the complex interactions
existing between you, your friends and the content you all like = mapping
your interests and cross-interests.
slide taken from http://www.slideshare.net/Saintsocial/facebook-open-graph-explained
14. It means that...
this kind
of
http://www.facebook.com/matteobrunati information is
IN the
cc:Likes Facebook

http://www.creativecommons.org
15. This graph around me is accessible from the new
GRAPH API, which links objects in the social graph via
CONNECTIONS...
URIs in effect
http://developers.facebook.com/docs/api
16. a sort of RDF model?

the object with the link

20. When “Mi piace” is clicked,

How Facebook knows the title and the site?
21. thanks to Metadata inserted in the page,
that transform the page in a Social Object...

http://opengraphprotocol.org/
26. Remember
the page on
the IMDB on
Fight Club?
IMDB Page source with OG,
the metadata
Let’s see metadata information using SIG.MA and SINDICE INSPECTOR
http://sindice.com/developers/inspector?url=http%3A%2F%2Fwww.imdb.com%2Ftitle%2Ftt0137523%2F#sigma
29. If the web page has no metadata
encoded using Open Graph Protocol,
Facebook show me only the title of that page
30. If the page has metadata
encoded using Open Graph Protocol and regular
Semantic Web vocabularies
http://www.metafora.it/leggi-internet/filirossi.html
33. What are the differences on the usage of RDFa
between Facebook and W3C guidelines?
Facebook developers tried RDFa and thought that
is too complex, so they use it in a minimal form
34. 1. URI -> property -> Literal value
Using the property attribute in RDFa, it means that
the object value in the RDF triple can be only a literal
value, a string of text.
35. 2. One page -> One social object
The instructions for the webmasters for the usage of the
Open Graph Protocol are clear: one page, one social
object.
And with a lot of pages? Administration problems, caos...
36. Problems
URIs are universal identifiers,
labels and text are not
If Pages on different sites are around the same
Social Object
The property attribute makes the content value a literal,
not a WEB RESOURCE with an URI, so
how understand this kind of information?
38. but the power of
decentralization of URIs
and the implicit web
capability of innovation
without consensus...
are with us .)
39. The Semantic Web community makes
the Scheme machine readable
http://github.com/facebook/open-graph-protocol/blob/master/schema.php
40. The Community makes some properties
of the Open Graph Protocol connected
with shared Semantic Web vocabularies
