I get tired of HTML and text in only natural language, I get tired of ftp, I also get tired of careful maintenance of my all online resources: Public BBS, Academic Notes, …. , and this homepage. It’s even hard for myself to find useful topics in the homepage, as it becomes bigger and bigger.
It’s time for semantic integration and some intelligence.
I’m trying to build a new site based on Semantic Web. Technologically, it’s a wiki system with the support of a controlled ontology, and some code work to convert old homepage into wiki pages. It will be ready probably in this month.read more
US has different statistic standard in urban population counting. Only 9 cities are listed as one-million-population city
- Los Angles,
- San Diego,
- San Antonio,
- New York
However, big cities usually covers more than one county, but the sub urban area is not counted in the city’s population. Whilst in China, lots sub urban agriculural population is also counted in.
In 2000, 49 cities in USA have more than 1 million population<br>

15 (and counting) Ways to Explore ISWC 2010 Data
This year at ISWC, when we worked on the metadata, we have a Data Consuming task force to develop tools that can browse/visualize the data many different ways, e.g., faceted browser, filter browser and mobile browser.
As soon as we have the basic dataset published, we immediately get feedback from people on off-the-shelf tools that can work with the data. The list is quickly growing. I collected the screen shots of some working instances (including tools the metadata committee has built) in a slides. I have no doubt that the number “15″ will be changed when the main conference begins …. in 2.5 hours! So expect some updates very quick.read more
At ISWC 2010, there are several on-going efforts to leverage Twitter data. Some ones that I’m aware of are:
Joshua Shinavier has helped to build a triple store (powered by AllegroGraph) that contains tweets related to the conference, along with basic ISWC metadata. Here is an example of SPARQLing with the triple store (details about tweets with tag #iswc2010 and #iswc). More examples and guide on how to use the triple store will be out soon.read more
ISWC2010 Metadata is Online
Below is an announcement I just sent for the ISWC2010 Metadata.
Dear SWers and LODers
ISWC2010 is around the corner and we are very excited about the coming week!
As in previous years, ISWC 2010 provides its basic metadata in RDF. The dataset gives details about authors, organizers, papers, events (e.g., sessions and talks), and some mappings to other linked data. The data is freely available at http://data.semanticweb.org/conference/iswc/2010, and can be downloaded as a single RDF file. There is a SPARQL endpoint  for this dataset, as well as for some previous ISWC/ESWC/WWW conferences. For more details about access, please refer .read more
ISWC 2010 Attendees by Country
This is a preliminary stat of ISWC attendees by country. Data is from registration list as of Oct 28, 2010, and the final data may be a little different. Also note that it’s different from the author/organizer data.
By no surprise, the host country China has the most attendees (15.4%). US, UK and Germany follow as the next biggest players (14.9%, 14.4%, 12.6%), respectively. By continents, we haveread more
A Word Cloud for ISWC 2010
Sharon Myrtle Paradesi of the DIG group, MIT, has helped us to generate a tag cloud for ISWC 2010. The input is abstracts of papers in the proceedings (i.e., research track, in-use track, doctor consortium track, and invited talks) and poster/demo proceedings. While I don’t know the full details of Sharon’s techniques, she applied a set of NLP algorithms (e.g., stemming, casing, and stop word removal, etc.) to make the cloud.read more
Timeline of ISWC 2010 Main Conference Talks
This is another visualization using Datapress
It shows talks at the main conference of ISWC 2010.
Visualizing Data using Datapress
I attended a seminar at MIT last Friday (for this year, I’m a part-time member of the DIG group there). Edward Benson gave an impressive demo on Datapress, an extension of WordPress that can enable non-geeks to import and visualize data in their blogs.
Since our TW blog is based on WordPress, I installed the extension and began to try. The installation was surprisingly smooth, just a few clicks and it’s done in 30 seconds!read more
OWL 2 Reference Card released
We’re pleased to announce the OWL 2 Reference Card . The Card is meant to be a “cheat sheet” of OWL 2 features printable on a single piece of paper (on both sides). It is based on the OWL 2 Quick Reference Guide , which is now a Proposed Recommendation  in the OWL 2 Web Ontology Language document set.
Background: OWL 2  is an extension to OWL 1 with a few new functionalities. Some of the new features are syntactic sugar (e.g., disjoint union of classes) while others offer new expressivity, including:read more
I will pay delicious $100 for hierarchical tagging
Just saw Jim’s post on What is the Semantic Web really all about?
I have been wondering about this problem too. What is Semantic Web? Yesterday I have asked a question “Why few (or none?) Web 2.0 sites provide hierarchical tagging?” on LinkedIn and get some pretty good answers:read more
A little, tiny semantics in action — from Google
I just read about Google’s Canonical Link Tag. It’s a little application of RDFa’s “rel” property. It is not yet a big thing, but I’m happy for that it is from Google, who seems quite remote from semantic web technologies so far.read more

From Talis: “Jim Hendler at the INSEMTIVE 2008 Workshop”
“that people will (and do) create metadata when there are obvious and immediate benefits in them doing so. No-one really consciously sits down to share or create metadata: they sit down to do a specific task and metadata drops out as a side-effect.”
I can not agree any more. I have tried to tag all my blogs once upon a time, after a few weeks, I found myself bored because there is no clear, immediate benefits for doing so. I would only tag things that I have to, like to tell my friends a list of posts of the same topic.read more

Cuil, Semantic Search
Last week, Cuil.com caught my eye. It gave me a very good impression in just 5 seconds (BTW, 10 seconds is a survival maximal for any website for me). First, I tried, as many people may do, my name. It didn’t disappoint me by hitting quite precisely my pages. I also love the grid-based layout. A few minutes later, I found its “Explore by Category” option. It looks like that Cuil has some sort of ontology hierarchies for web pages.read more
