My first experiences with Twine
Today finally I logged in to Twine the first time. I was reading yesterday about some shortcomings of the system, so I was keen on trying out the system by myself to get my own impression.
It´s true that the system isn´t as easy to understand as del.icio.us or other bookmarking tools. It takes a while until you get used to all those additional ways you can navigate through the system. Remember: “Twine looks at content and parses it automatically for the names of people, places, organizations and other subject tags. Users are then able to navigate between related content, view recommended content and connect with recommended people with related interests.” – But the “shortcoming” mentioned by Marshall Kirkpatrick that “… it’s hard to keep track of all the levels and types of information available” I can´t agree with: This has only to do with a general problem, which arises whenever semantic technologies should enhance the user experience. Either you stay with “simple” user-interfaces like Google or del.icio.us or you spend 5 minutes or so to learn a new piece of software which will help you to save time in the future and which helps you to find related information automatically.
On the other hand I was very surprised, that the automatic recommendations Twine makes on how to annotate or describe a new resource is really unsatisfying. Users will only spend time to tag their bookmarks if the machine comes up with some intelligent suggestions. And it´s true, as Marshall says, “most of the web is made up of ugly, non-standard pages.”
So hopefully Twine will add that feature before it will open up to the public (isn´t there a plan to integrate OpenCalais or something similar?), otherwise there will be no “first mainstream semantic web application” but only another prototype of a yet another semweb-app.
Zimbra is the Collaboration Suite for the Social Semantic Web
We´ve been using Zimbra since a couple of months now, and I think it´s a fantastic opportunity for each small or medium enterprise, especially when virtual teamwork becomes more and more important (like in my working environment), to make a step towards Web 2.0. Besides typical features a collaboration suite usually offers, Zimbra comes with a couple of concepts which have the potential for a “Next Generation Collaboration” (collaborate or collapse):
- Zimbra comes with a powerful search engine based on Lucene
- Zimbra has an integrated tagging-system
- Zimbra´s spam filter learns from each user in the system, if an email is spam or not – a very good example for an application of collective intelligence
- Zimbra´s Zimlets support meshups and with that mechanism any message content can be made “live” by linking it with other services and content (eg. if in a textpassage the word “today” appears it will automatically be linked with your calendar entries from “today”)
And: Zimbra can be synchronised with your PDA…
Scripting for the Semantic Web
This year´s ESWC hosted the 3rd International Workshop on “Scripting for the Semantic Web” (SFSW 2007). I really enjoyed that event, also because of the very friendly and relaxed atmosphere in that community. Danny Ayers started with a talk called “Two Webs!“. He pointed out the ways to use the “Semantic Web” (again: it´s NOT a completely new web aside Web 2.0!) as an “RDF-Bus” where existing data sources can be interlinked quite easily (see: LinkingOpenData @ SWEO).
- Michael Hausenblas presented “PSIMeter” which is a demo to show alternative ways to RDF-ize the flickr API regarding machine tags.
- Chris Bizer outlined once more the importance of the “Web of (open) data” and presented The RDF Book Mashup: From Web APIs to a Web of Data (For a demo go here)
- Eyal Oren was talking about two services which play an important role in a Semantic Web infrastructure: Sindice and Ping the Semantic Web
- Uldis Bojãrs and some others from the SIOC project presented their ideas and I really liked the SIOC Browser.
- And finally the brilliant Ripple won the Semantic Scripting Challenge (Paper).
I also enjoyed talking with Sören Auer, Chris Bizer, Danny Ayers, Tom Heath and some others very much. Thanks to the organizers!

together with Leo Sauermann talking about the Semantic Desktop “war mir ein großes Volksfest”. Thanks Leo!
