Thomson Reuters has released their 2009 Journal Citation Report and we are happy to see that the Journal of Web Semantics impact factor has risen to 3.412, the fifth highest among the 116 journals in its category, “Computer Science, Information systems.” This is the highest impact factor score for the JWS to date.
Thomson Reuter’s journal impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The 2009 impact factor is computed as the citations received in 2009 from journals indexed by Thompson to all JWS articles published in 2007 and 2008, divided by the number of JWS “source items” published in 2007 and 2008.
Journal impact factors are not perfect measure of a journal’s quality, but are generally regarded as meaningful and, perhaps, the best objective measure we have. Our high ranking is a very good sign and a testament to the hard work of many people — area editors, editorial board, advisory board, reviewers, authors and especially Silke Werger, who runs the JWS editorial office. We thank everyone for all of the work — it’s made a difference.

The newly restored complete version of Metropolis opens tonight the Senator Theater for a one-week run. If you like movies about robots, or dystopian futures or just like classic fims that made a difference, it is well worth seeing.
Baltimore is lucky to be one of about ten cities in the US screening it this summer and the only one on the east coast outside of Boston. From the Baltimore Sun
“This “complete” version of Lang’s silent sci-fi extravaganza restores all of its subplots and nearly all of its surging imagery. With Gottfried Huppertz’s soaring romantic score heard in full for the first time, “Metropolis” offers an engulfing audiovisual experience. It leaves you shaking your head in wonder and disbelief.
Those new to the film can sit back and be overwhelmed. Those who’ve seen it have the additional pleasure of watching a puzzle solved before your eyes. Roughly 25 minutes longer than the 2002 version, this print of “Metropolis” uses footage from a 16-millimeter dupe negative found in Buenos Aires to fill in some major bits and pieces — and some minor ones.
You can tell the 16-mm footage from the drop in picture quality. But the effect is thrilling, not jarring. This print combines the ecstasy of seeing a peak accomplishment in pristine form with the frisson movie-lovers get from viewing films as artifacts of their time, aging the way gardens or buildings do.”

UMBC Computer Science alumnus Ralph Semmel (PhD. 1991) was just named as the next director of the Johns Hopkins University Applied Physics Laboratory. APL has a staff of 4,600 and an annual funding level of about $980 million. Dr. Semmel’s dissertation, A knowledge-based approach to automatic query formulation, developed novel techniques to disambiguate conceptual queries against a relational database. His dissertation research was supervised by his mentor, Computer Science Professor James Mayfield. We congratulate Ralph and wish him well in his new position.

Here’s a quick trick that could significantly speed up your Web surfing. Download and run the open source namebench on your computer. It does a thorough test of your current DNS servers and some other popular global and regional alternatives, produces a good report and recommends which ones you should use.
Here is how namebench describes what it does:
“namebench looks for the fastest DNS (Domain Name System) servers accessible to your computer. You can think of a DNS server as a phone book: When you want to dial a company on the phone, you may have to flip through a phone book by name to find their phone number. On the Internet, when you want to visit “www.google.com”, a DNS server needs to looks up the correct IP Address for you.
Over the course of loading a single web page, your computer may need to look up a dozen of these addresses. While your Internet provider usually automatically assigns you one of their servers to handle looking up these addresses, there may be others that are significantly faster. namebench finds them.”
Namebench also points out which DNS servers do DNS hijacking — typically by intercepting the error message produced by entering a mistyped URL (e.g., http://umbc.edo/) and redirecting you to a page full of ads and “helpful” search results. Some name severs, like OpenDNS, will also automatically correct some mistyped URLS, e.g., guessing that then you typed http://umbc.edi/ you meant to type http://umbc.edu/. (Shades of DWIM!) It’s not dangerous and is a way private DNS services, like OpenDNS, get revenue to support the service and make a profit.
I have been using OpenDNS because it’s the fastest (for me) and don’t mind their NXDOMAIN hijacking. But I learned from namebench that OpenDNS reroutes www.google.com to google.navigation.opendns.com. That site redirects HTTP GET requests to and then from there onto http://www.google.de/. And Google itself redirects HTTP GET requests for http://google.com/ to http://www.google.com/. I’ll admit I am a bit confused by this. I imagine they do this to capture queries sent to Google, which provide very useful information even in the aggregate. OpenDNS says that they are doing this to correct a problem with Google-specific software installed on Dell computers. They do not seem to be doing this for Microsoft’s Bing search engine, which does lend some credence the claim. I plan on digging into this more to fully understand what is going on and why.
Namebench runs on Macs, Windows and UNIX, and has both a command line and graphical user interface. See the namebench FAQ for more information.
