A Thought on a Reasoner-enabled Version of Del.icio.us (and perhaps Technorati)

I have been adding more bookmarks to my del.icio.us account and have begun tagging them with RDF-like object/datatype properties. Adding more and more object/datatype properties to the bookmark, a provoking thought popped up:

It would be nice if tagging can be assisted by ontologies and a logic reasoner. Look at del.icio.us/thitiv. The _hasAffilication:CUPhoto property should be a subproperty of _hasAffiliation:Chula (provided that CUPhoto stands for Chula Photo Club.) Also, aticles on 'tagging' are subclass of articles on 'metadata'. But articles on 'metadata' are not essentially the articles on 'tagging'. 'Friends' versus 'people' is also another example. Bookmarks about my friends are of course bookmarks about people. But not all the people I know or found on the Internet (through search engines) are my friends. Ontology-assisted tagging sounds promising to solve this problem.

In principle, this problem is partly related to what mentioned in the MIT's Piggy Bank paper submitted for International Semantic Web Conference (ISWC) 2005 and I am looking into it.

Tips: Mac OS X: Full ANSI Color Support in Terminal.app

I'm trying to switch my Java development platform from Windows XP to Mac OS X Tiger. Wondering how to colorize the Terminal screen, I spent some time googling. From the discussions at the end of this page: macosxhints.com - Add full ANSI color support to Terminal.app Here's a summary of how to enable it: With bash shell as default, simply add export TERM=xterm-color [I prefer this for Linux compatibility] or export TERM=dtterm in the ~/.profile (single-user) or /etc/profile (system-wide) Color terminal is enabled. Use ' ls -G ' (the -G enables color output) to test. Add alias ls='ls -G' in the profile file for convenience. Keywords: mac-os-x , unix , terminal , shell , tips

iTunes: Error 261 while Burning Data CDs/DVDs

Apple Discussions: 261 error while burning MP3 CD. I usually put an aphostrophe (') in the name of playlists and was having error 261 burning CD/DVD data discs since iTunes 5.1. Upgrading to iTunes 6.0 for Windows doesn't help. I was burning a music DVD this morning and had Error 261 again. So I went to Apple iTunes Discussions site and look for a thread on this. Viola! There are many people having the same problem as mine. The thread ends at a point where someone removing ampersands, the '&' symbols, from their playlists and could avoid this error. I tried removing aphostrophes from the name of my playlist because aphostrophe falls into the kind of non-alphabet characters that needs escaping in some programming languages. It works!!

Microsoft Office Outlook Connector 12.1 Beta 2 Crashes Thai Language Input in Outlook 2007

It's been more than a year since I last blogged. I've been busy with work and also don't know what to blog. Here comes my new findings: Microsoft Office Outlook Connector 12.1 Beta 2 + Outlook 2007 + Thai Language Input = CRASH This has also been proven here . I downloaded the Outlook Connector the other night for improved supports to Windows Live Hotmail -- only to find that whenever I start typing e-mails in Thai, i.e., hit the "language switch" key Outlook simply crashes! I googled for " outlook 2007 crash language switch " this morning and find someone having the same Outlook Connector insta.led and the same problem as mine. So, Outlook Connector is most likely the cause of trouble. I uninstalled Outlook Connector this morning and, yes, typing in Thai doesn't crash Outlook 2007 anymore!
