QOTD: in discussions, we negotiate points of view

April 30th, 2012

“Wikipedia discussions can thus be seen as a mirror of a stream of public consciousness, where those elements which are still not part of a shared consolidated heritage are object of a continuous negotiation among different points of view.”

There is No Deadline – Time Evolution of Wikipedia Discussions. (2012) Andreas Kaltenbrunner, David Laniado. arXiv:1204.3453v1

Juxtaposition 2

April 1st, 2012

From today’s Twitter stream, more juxtaposition:


Gabriela Avram: #LmkTH You’re half way through, and you’re all doing a fantastic job! Keep on the good work!

Laura Dragan: 50% done – #21k in 2h30min – not looking fwd to the hills that are coming :) sun still shining ..loving it!

I’m amused because Gabriela’s comment about the Limerick Tweasure Hunt could be a great reply to Laura’s Connemara marathon status update.

A whirlwind look at Bottlenose

March 1st, 2012

Marcel asked:
>http://bottlenose.com/
>anyone with experiences and opinions about it?

Definitely worth trying–it focuses on your network in order to pull more interesting stuff to the fore. I put it in my bookmar bar when I first encountered it — it was briefly useful (slowed down the stream, found things that my network had heavily retweeted, making interesting suggestions of the few things I should read).

Its classification is ok — the genre classification seems decent (news/videos/pictures) — the message type classification (Question/Opinion/Notification/Check-In/How-To/etc) seems less exact, but may still be useful.

It kept suggesting the same things so I stopped checking it regularly — but I just checked it and am intrigued since they’ve added some features. In particular, they seem to be pulling out keywords (you can visualize one/all of people, topics, hashtags, message types–see screenshot). That might be especially interesting when doing exploratory searches.

There’s also a lot of customization possible — you can make your own rules for what to put in streams, and they have a wizard (screenshot below):

If there were a marketplace for sharing rules, that might be good — I’m not likely to spend time on customizing my own, so I’m just relying on the defaults (‘suggested for you’ and ‘popular’).

I’d be cautious of posting from Bottlenose without first checking the documentation — they accept posts of any length, but may also modify them (add hashtags, say).

I suppose for some people, the ability to pull in from multiple networks (for now Twitter & Facebook) could be useful, though there are lots of tools that do that.

I’d be curious to hear what other people think–have you found uses for Bottlenose?

-Jodi
PS-They seem to be going by klout score for invites for now; if you can’t get in that way, give me a shout (I’ve 10 invites if you want one).

I’m taking a listserv post as the source of a blog post again; channeling jrochkind I suppose.

Karen Coyle on Library Linked Data: let’s create data not records

January 12th, 2012

There have been some interesting posts on BIBFRAME recently (noted a few of them).

Karen Coyle also pointed to her recent blog post on transforming bibliographic data into RDF. As she says, for a real library linked data environment,

we need to be creating data, not records, and that we need to create the data first, then build records with it for those applications where records are needed.

Quantified Self Europe, Saturday morning.

November 26th, 2011

What is this Quantified Self stuff, anyway? Here’s a brief intro (prettier PDF version) Nathan Yau and I wrote.

This weekend I’m in Amsterdam for Quantified Self Europe. So far this morning I’ve met Arduino hackers, seen several talks about monitoring heart rate (continuously, cool, or even with swimming goggles) and lung capacity. Oh, and given a talk about Exercise and Weight tracking.

There’s lots of blogging/photoblogging going on. Twitter hashtag (formerly #QSelfEurope) is #QS2011.

Time-based comments

November 14th, 2011

I’ve been digging SoundCloud lately.

Today I noticed time-based comments in their tracks. It’s a bit disorienting to have comments pop up as you’re listening. Maybe after adjusting, there’s a pleasant sense of having a conversation going on around you. Definitely feels like you’ve got company!

Comments pop up as the track plays

Avatars appear below the track to indicate that there are comments, and you can scroll over avatars to read comments. You can also hide the comments if you prefer.

Comments are indicated by avatar icons in the full view.

YouTube “I dislike this” button

November 14th, 2011

A few weeks ago, I noticed something new on YouTube: an “I dislike this” button.

I wonder how long that’s been there?

 

When I talk about online argumentation, a frequent comment is “too bad there’s only +1 and Like; we need more expressivity”.

Support EPUB!

November 7th, 2011

EPUB is just HTML + CSS in a tasty ZIP package. Let’s have more of it!

That’s the message of this 3 minute spiel I gave David Weinberger when he interviewed me at LOD-LAM back in June. Resulting video is on YouTube and below.

Ways to use the crowd

November 6th, 2011

Loro Aroyo gave a talk in DERI on Friday, based on her “Crowdsourcing community science” slide deck. She was in town for Smita‘s viva. This is a deck of interest to anybody in digital cultural heritage.

The slide on “Ways to use the crowd” seemed particularly useful to me:

  • tagging & classification
  • editing & transcribing
  • contextualising
  • acquisition
  • co-curation
  • crowdfunding

Frank van Harmelen’s laws of information

November 1st, 2011

What are the laws of information? Frank van Harmelen proposes seven laws of information science in his keynote to the Semantic Web community at ISWC2011. ((He presents them as “computer science laws” underlying the Semantic Web; yet they are laws about knowledge. This makes them candidate laws of information science, in my terminology.))

  1. Factual knowledge is a graph. ((“The vast majority of our factual knowledge consists of simple relationships between things,
    represented as an ground instance of a binary predicate.
    And lots of these relations between things together form a giant graph.”))
  2. Terminological knowledge is a hierarchy.
  3. Terminological knowledge is much smaller ((by 1-2 orders of magnitude)) than the factual knowledge.
  4. Terminological knowledge is of low complexity. ((This is seen in “the unreasonable effectiveness of low-expressive KR”: “the information universe is apparently structured in such a way that the double exponential worse case complexity bounds don’t hit us in practice.”))
  5. Heterogeneity is unavoidable. ((But heterogeneity is solvable through mostly social, cultural, and economic means (algorithms contribute a little bit). ))
  6. Publication should be distributed, computation should be centralized to decrease speed: “The Web is not a database, and I don’t think it ever will be.”
  7. Knowledge is layered.
What do you think? If they are laws, can they be proven/disproven?

Semantic Web vocabularies in the Tower of Babel

I wish every presentation came with this sort of summary: slides and transcript, presented in a linear fashion. But these laws deserve more attention and discussion–especially from information scientists. So I needed something even punchier to share, (prioritized thanks to Karen).
