The Linking Open Data project recently struck me as very similar to the early web, when it made sense to publish periodic updates to what interesting new data had been made available.
The following entries were written in the Semantic Web category:
I’m in Innsbruck, Austria attending the Fourth European Semantic Web Conference. I’m putting some photos of the conference on Flickr, and will be posting some notes on papers and presentations that stand out. Up first is “SPARQLeR: Extended Sparql for Semantic Association Discovery”, an extension to SPARQL for constrained path queries.
Version 1.041 of RDF::Query hit CPAN a few days ago.
The International Semantic Web Conference is currently taking place here in Athens, Georgia, and it’s been really great so far.
In my recent work on PhotoStuff, I’ve been working in Java on the Mac. PhotoStuff is full of features, but I often find the interface frustrating and confusing. This is especially true on the Mac where many of the UI elements end up being in the wrong place and looking very un-Mac-like. It’s worth spending some time to make some (mostly simple) changes to PhotoStuff to make it act a bit more Mac-like.
I’ve been putting a lot of work into pure-perl RDF classes recently, and have been frustrated by some ongoing issues.
It’s been around for a few days now, and I’ve got mixed feelings about Flickr’s new geo-tagging support. On one hand, they’ve done more for the cause of spatial photo annotations in the last few days than anyone has ever done before. On the other hand, the data still ends up being controlled by Flickr, and the simple coordinate approach to geo-tagging means that you can’t attach any other interesting data off of locations.
ESWC went really well. The Scripting workshop was quite good, making me a bit sad that I missed last years’ at which I was supposed to present a paper. The conference proper was also good, but the hallway (beach) track was far superior to most of the presented talks.
As I promised in Personal Report, the other day I sat down and wrote some code to pull together some personal data and consolidated it on my about page. Currently, the data I’ve got updating nightly is: recently watched movies, recently listened to music, and beer I’ve had recently (which is compared to my beer data from 2004).
For those that haven’t heard, I was recently accepted to a Ph.D. program in Computer Science starting in the fall at the University of Maryland. So starting in August, I’ll be moving to DC for roughly five years.
I try to make a lot of the information in my life public. Photos, travels, movies, music, how I organize files on my computer, and even what beer I’m drinking. But I’ve never really felt like I’m conveying this information in as interesting a way as it deserved.
I’ve just made public a feature on this website I’ve been playing with for several months. After discussion privacy issues at ISWC with Libby and Bijan, I added support on the photo pages for marking individual photos as private. The idea here is that if you’re in a photo, you have the option of taking it offline.
I’ve just uploaded a new version of RDF::Query (version 1.028) to my site, and it should be available from the CPAN shortly.
I’m finally back from Ireland (and England) and ISWC. There are pictures online from the conference and my weekend in London.
I’m back at the airport. Again. Back to LA for a week. I’ve got lots of work to do while there, and lots of other things to take care of, but I promise, I’m going to start posting more often.
I’ve just released RDF::Query 1.027, tracking some of the changes in the latest SPARQL draft.
Just got an email from Sören Auer alerting the authors from SFSW that the papers, including my MT-Redland paper, are now online.
I’ve just released version 1.020 of RDF::Query including preliminary support for SPARQL OPTIONAL graph patterns. It hasn’t been tested a tremendous amount, but it seems to work on the simple stuff. Also included in this release are support for the SPARQL Query Results XML Format and miscellaneous bug fixes.
I’ve now got initial support for ASK, DESCRIBE and CONSTRUCT SPARQL queries in RDF::Query.
Installed Tiger tonight, and things went surprisingly smoothly. GPGMail freaked out, and some of my extionsions were missing after the upgrade (Synergy, SSHKeychain), but mostly things are working. Haven’t tried MySQL or Redland, yet, though.
My MT-Redland paper just got accepted to SFSW at ESWC2005. Now I need to figure out how to make some changes without going over the page limit.
Spurred on by Libby’s work with cross-querying with Joseki, I’ve put up v1.014 of RDF::Query which will run queries with proper FILTERs, including custom function filters. Here’s an example of a custom function for finding images within a certain radius of a point.
I’ve resurrected my RDF::Query project, and added initial SPARQL support (with the new Turtle syntax!).
I’ve just emerged from two weeks of writing a paper on MT-Redland for SFSW2005.
Shelly over at Burningbird has been doing some really great things with Wordform. It’s a much grander project in scope than MT-Redland, but they share some common themes of using weblogging tools and RDF to allow the creation of new semantic metadata, and I’m very impressed with the work Shelly’s doing.
I’ve just put version 0.007 of MT-Redland online. This release mostly addresses the speed issues I talked about yesterday, which have been greatly improved. Also, I’ve got initial support for SKOS categories in CVS.
With a few code cleanups, and checks to make sure the query returns the appropriate nodes, I’ve got a working version of an RDQL search returning RSS, and using it in an aggregator.
Because Google refuses to find files that are linked to in both my RDF and in my HTML rel=”alternate” headers, here’s a page with links to all the individual RDF files describing photo albums on kasei.us.
I’ve put up version 0.004 of MT-Redland, and I think it’s coming along really well. Here are some updates including screenshots of the interface to add semantic metadata, and a new search results page based on an RDQL query.
I’ve put up a new version of MT-Redland (v0.002), with a bunch of new features including hooks into the MT CMS code, allowing interface changes to the edit entry page.
In the spirit of release early, release often, I’m posting a first draft of a Movable Type ObjectDriver (storage backend) that uses Redland and mysql.
I’ve been doing terribly at updating this month. Really quite awful. So here’s a recap of the month.
I’ve just submitted a lot of changes to the Image Description FAQ over on the FOAF Wiki.
With a working computer back in my life, I’ve been cleaning up some code, and making some changes to the website.
Optimizing the image search continues. It’s much faster now than a few days ago (again), but still slow for interactive use. Here’s a screenshot, though, to tide you over.
I had intended to write a short bit about why you wouldn’t be able to browse pictures on this site by location for a long time, but two days of solid hacking on an good-enough solution using RDQL has gotten me so much closer than I would have thought possible just a few days ago.
There are now 8642 photos, at least partially annotated, on this site.
I’ve been putting tons of work into the photo annotation code, and am about ready to tackle the trip photos. To test the code, I’ve been adding lots of new pictures, and going back and annotating lots of old pictures.
Libby wrote up our (Morten, Libby, and myself) thoughts on image annotation, including the geo-spatial stuff, and put it online at the ESW Wiki
I was thinking about how nice it would be to hook it up to the IRC channels I frequent, both on the front-end and the back-end.
Nils Erik Svangård just posted to the dashboard-hackers list regarding the possibility of adding a voice recognition cluepacket generator to dashboard.
Morten, Libby, and I sat down over pints last night to hash out the image creation event semantics and markup.
Libby has posted a first cut at the issues brought up for an Image Description FAQ at yesterday’s breakout session.
The image annotation session at FOAF Galway was really good.
I’ve arrived in Galway, and am now waiting for the FOAF Workshop to begin.
I talked with some of the folks on #rdfig today about my RDF mapping, and got some good suggestions and pointers.
I’ve hacked up some geo-locator code to pull locations from RDF and map the result on a world map.
I’m not sure how useful it would be in practice, but I like the idea of being able to infer location of people based on the RDF in my weblog, photos, and beer feeds.
You can now search for photos on this site by place name, latitude/longitude pairs, and Wordnet terms.
So Simon and I drank yards together last night at Sunset. On the topic of beer, as of today I’m making my beer drinking habits (“problem”?) public for all to see. I’ve started generating graphs of total beer consumption, beer types, and locations of drinking. Also, the list of beers these graphs are generated from are available as a text file, or as a hacked-up, work in progress, RDF file.
