Topic Maps and Semantic Search

Tonight was another one of the monthly users' group meetings on Topic Maps, and tonight the subject was Topic Maps and Semantic Search. There were two presentations, one on Compass, a Topic Maps search tool, and a case study of a Norwegian web site. ...

Upcoming Topic Maps events

There are quite a few upcoming Topic Maps-related events here in Oslo, so I thought I'd do a summary of them. Firstly, there is a user's group meeting tomorrow (January 30th) on Topic Maps and semantic search. This meeting was so popular (at least 70 people signed up) that they've had to move it from the course room to the canteen. On February 27th there will be another user's group meeting on "Topic Maps and Web 2.0"; details on that will appear later, but you may want to pencil it in now. ...

CTM: What is it, and why is it needed?

ISO has been working on CTM (Compact Topic Maps syntax) for a while now, but very little has been published about it yet. I got a question about it by email, and decided to blog about it in case others were curious, too. ...

A visit to Haandbryggeriet

On Friday I went to Drammen for a tour of Haandbryggeriet, one of the new Norwegian craft brewers. We were treated to a tour round the brewer itself, got to taste four of their beers, and then went pub crawling in Drammen. The tour is a standard service offered by the brewery, and we were told they have groups coming about once a week. At 80 NOK per person it's a really good offer in my opinion. ...

Two Stalin biographies

Svein's recent review of Simon Sebag Montefiore's Stalin biography finally made me write up some book reviews I've been planning for a long time. Originally I planned a posting with a "Russian bibliography", consisting of the books on Russia I read the last couple of years, both to prepare for the holiday, and because I'm interested. I had to stop after four books, however, since it became clear that this would be much too long for one posting. So here are the two Stalin biographies, at least. Whether any more will appear remains to be seen. ...

Comparing Topic Maps and RDF

The Topic Maps and RDF technology stacks are quite complex, and it's not easy to see how the various pieces compare. So I thought I'd write a little bit about this. It was Trond's comment that triggered this, but I've seen no end of people struggle with this. I've written about this before, but I think it's possible to do a lot better. So, here goes. ...

Travels in 2006

Last year I did a Google Map of my travels in 2005, and so of course I wanted to do it again this year. I'd written scripts that built the map from my photo topic map, but they were lost with the old laptop. That meant I had to write them all over again, but the benefit is that they are much cleaner this time around. It gave me a nice, recreational task that didn't require too much concentration to do over Christmas, too. (For more detail on how it was produced, see last year's posting.) ...

Published subjects and PSIs

People often find the basic idea of published subjects quite clear and simple, but stumble over the detail, so I thought I'd write a little overview over the territory. The idea is to sketch out the basic concepts and how it all works. ...

A new book on Topic Maps

Those of you who have been waiting for a new Topic Maps book will be happy to hear that one has just been published. It was edited by Naito-san with the contributions of several Japanese people (Komachi-san, at last, but also others), if I read the cover correctly. And, yes, it was written in Japanese, so if, like me, you cannot read Japanese you'll have to settle for looking at the pictures. ...

Some thoughts on identity

The concept of identity is at the heart of both Topic Maps and RDF, and consequently it has been much discussed over the last few years, but I've seen very little writing on what identity itself actually is. This posting offers some thoughts on that. ...
