Social Bookmarks ist eine des wichtigsten Merkmals von Web2.0, sie dienen als persönliche Linkssammlung und Austauschplattform. Mit Social Bookmarks kann man die Informationen sammeln und durch persönliches Verschlagwortung (Tagging) die Websites wieder finden zu können. Und das Wort „Social” sagt auch aus, dass die Bookmarks im Netz veröffentlicht werden und mit anderen Nutzern teilen können.Durch Tagging werden die Informationen im Internet wieder suchbar gemacht, aber viele Nachteile bei Social Bookmark können die sorgfältigen Bibliothekare, die jahrelang mit Schlagwörtern gearbeitet haben, sofort nennen: keine einheitliche Nutzung von Tags, unklare Bedeutung von Tags, die von Nutzern vergebenen Tags können nicht als standardisierte Metadaten verwendet werden und damit die gesammelten Informationen in Social Bookmark Plattform nur eingeschränkt ausgetauscht und gefunden werden.
- Must have in 2009: A Cyberterrorist Love LetterJanuary 1
-
I have been quiet the entire vacation time to put in some time doing content for our companies under MJS Global Group: MJS Strategies, MJS Commodities, MJS Capital, etc. I have been putting it off for quiet sometime so I decided to buckle down with the help of some associates. After countless hours back and forth sharing and working through them despite of the time zones, I got the news today that we got hacked by this guy and all the files got infected and therefore we have to work from scratch again. We have notified Hostmonster and they have not responded due to the holidays.
My Love Letter from a Cyberterrorist
This is my first experience on cyberterrorism. On the positive note I am glad we are still in the beginning stages, however, I already did 70 pages worth of content. What a way to start the year.

- Quantum Reasoners Hold Key to Future WebDecember 25 2008
-
Last year, a company called DWave Systems announced their quantum computer (the ‘Orion’) - another milestone on the road to practical quantum computing. Their controversial claims seem worthy in their own right but they are particularly important to the semantic web (SW) community. The significance to the SW community was that their quantum computer solved problems akin to Grover’s Algorithm speeding up queries of disorderly databases.
Semantic web databases are not (completely) disorderly and there are many ways to optimize the search for matching triples to a graph pattern. What strikes me is that the larger the triple store, the more compelling the case for using some kind of quantum search algorithm to find matches. DWave are currently trialing 128qbit processors, and they claim their systems can scale, so I (as a layman) can see no reason why such computers couldn’t be used to help improve the performance of queries in massive triple stores.
What I wonder is:
- what kind of indexing schemes can be used to impose structure on the triples in a store?
- how can one adapt a B-tree to index each element of a triple rather than just a single primary key - three indexes seems extravagant.
