NIST Big Data Workshop, 13-14 June 2012

May 31st, 2012, by Tim Finin, posted in cloud computing, Conferences

NIST will hold a Big Data Workshop 13-14 June 2012 in Gaithersburg to explore key national priority topics in support of the White House Big Data Initiative. The workshop is being held in collaboration with the NSF sponsored Center for Hybrid Multicore Productivity Research, a collaboration between UMBC, Georgia Tech and UCSD.

This first workshop will discuss examples from science, health, disaster management, security, and finance as well as topics in emerging technology areas, including analytics and architectures. Two issues of special interest are identifying the core technologies needed to collect, store, preserve, manage, analyze, and share big data that could be standardized and developing measurements to ensure the accuracy and robustness of big data methods.

The workshop format will be a mixture of sessions, panels, and posters. Session speakers and panel members are by invitation only but all interested parties are encouraged to submit extended abstracts and/or posters.

The workshop is being held at NIST’s Gaithersburg facility and is free, although online pre-registration is required. A preliminary agenda is available which is subject to change as the workshop date approaches.

CS conference selectivity and impact

May 29th, 2010, by Tim Finin, posted in Conferences, CS

The June 2010 CACM has an interesting article by Jilin Chen and Joseph Konstan of the University of Minnesota on Conference Paper Selectivity and Impact. The abstract gets right to the point:

“Studying the metadata of the ACM Digital Library (http://www.acm.org/dl), we found that papers in low-acceptance-rate conferences have higher impact than those in high-acceptance-rate conferences within ACM, where impact is measured by the number of citations received. We also found that highly selective conferences — those that accept 30% or less of submissions—are cited at a rate comparable to or greater than ACM Transactions and journals.”

A key paragraph later in the paper has some more detail:

“Addressing the second question— on how much impact conference papers have compared to journal papers — in Figures 3 and 4, we found that overall, journals did not outperform conferences in terms of citation count; they were, in fact, similar to conferences with acceptance rates around 30%, far behind conferences with acceptance rates below 25% (T-test, T[7603] = 24.8, p< .001). Similarly, journals published as many papers receiving no citations in the next two years as conferences accepting 35%–40% of submissions, a much higher low-impact percentage than for highly selective conferences. The same analyses over four- and eight-year periods yielded results consistent with the two-year period; journal papers received significantly fewer citations than conferences where the acceptance rate was below 25%."


Impact of CS conferences vs. journals

Impact of CS conferences vs. journals



We have to assume that this study is only applicable to Computer Science, for which the ACM digital library is a very good sample, and not other disciplines (e.g., EE) or even narrow sub-disciplines within CS. Different disciplines have very different publication patterns. But it does confirm our own anecdotal evidence from tracking citations to papers written in our ebiquity lab over the past ten years — those published din top conferences tend to get more citations than those in journals.

CFP: Semantics for the rest of us Workshop at 8th Int. Semantic Web Conference

Semantics for the Rest of Us: Variants of Semantic Web Languages in the Real World is a workshop that will be held at the on 26 October 2009 in Washington, DC.

The Semantic Web is a broad vision of the future of personal computing, emphasizing the use of sophisticated knowledge representation as the basis for end-user applications’ data modeling and management needs. Key to the pervasive adoption of Semantic Web technologies is a good set of fundamental “building blocks” – the most important of these are representation languages themselves. W3C’s standard languages for the Semantic Web, RDF and OWL, have been around for several years. Instead of strict standards compliance, we see “variants” of these languages emerge in applications, often tailored to a particular application’s needs. These variants are often either subsets of OWL or supersets of RDF, typically with fragments OWL added. Extensions based on rules, such as SWRL and N3 logic, have been developed as well as enhancements to the SPARQL query language and protocol.

This workshop will explore the landscape of RDF, OWL and SPARQL variants, specifically from the standpoint of “real-world semantics”. Are there commonalities in these variants that might suggest new standards or new versions of the existing standards? We hope to identify common requirements of applications consuming Semantic Web data and understand the pros and cons of a strictly formal approach to modeling data versus a “scruffier” approach where semantics are based on application requirements and implementation restrictions.

The workshop will encourage active audience participation and discussion and will include a keynote speaker as well as a panel. Topics of interest include but are not limited to

  • Real world applications that use (variants of) RDF, OWL, and SPARQL
  • Use cases for different subsets/supersets of RDF, OWL, and SPARQL
  • Extensions of SWRL and N3Logic
  • RIF dialects
  • How well do the current SW standards meet system requirements ?
  • Real world “semantic” applications using other structured representations (XML, JSON)
  • Alternatives to RDF, OWL or SPARQL
  • Are ad hoc subsets of SW languages leading to problems?
  • What level of expressive power does the Semantic Web need?
  • Does the Semantic Web require languages based on formal methods?
  • How should standard Semantic Web languages be designed?

We seek two kinds of submissions: full papers up to ten pages long and position papers up to five pages long. Format papers according the ISWC 2009 instructions. Accepted papers will be presented at the workshop and be part of the workshop proceedings.

Videos from ISWC 2007 online

November 17th, 2007, by Tim Finin, posted in Conferences, iswc, Semantic Web, Social media

Videolectures.net was recording talks at the 6th International Semantic Web Conference and the 2nd Asian Semantic Web Conference (ISWC 2007) held in Busan, South Korea this week. They already have up two of the three keynote talks and one tutorial.

This is a great service run by the Jozef Stefan Institute. The videos of computer science talks, lectures and tutorials are professionally recorded and edited and provide a wonderful resource to the international computer science community.

The ISWC 2007 talks that have already been put online are:

See Videolecture’s ISWC 2007 page for the complete set of videos. I expect to see many more from ISWC 2007 in the coming weeks.

AAAI-06: AI and the Web

December 7th, 2005, by Tim Finin, posted in Agents, AI, Conferences, KR, Ontologies, Semantic Web, Web

AAAI-06 will include a special technical track on Artificial Intelligence and the Web. This year’s conference will Celebrate “Fifty Years of Artificial Intellligence” and be held at the Seaport Hotel and World Trade Center in Boston 16-20 July 2006. The deadline for submitting papers is 16 February 2006.

The track is especially interested in receiving papers in two active research areas: (i) using text and language analysis to interpret and understand natural language text found on the web and (ii) developing and exploiting Semantic Web languages and systems that explicitly encode knowledge using languages such as RDF and OWL. Innovative papers in other areas describing research involving both AI and the Web are also encouraged. See the track web site for details.

Models of trust for the Web

November 23rd, 2005, by Tim Finin, posted in Conferences, Policy, Security, Semantic Web, Web

The Workshop on Models of Trust for the Web (MTW’06) will be a one-day workshop held on May 22 or 23, 2006 in Edinburgh in conjunction with the 15th International World Wide Web Conference. Tentative deadlines are January 10 for paper submission and February 1 for acceptance notification.

“There are three types of lies – lies, damn lies, and facts found on the Web.” — anon

“As it gets easier to add information to the web via html pages, wikis, blogs, and other documents, it gets tougher to distinguish accurate information from inaccurate or untrustworthy information. A search engine query usually results in several hits that are outdated and/or from unreliable sources and the user is forced to go through the results and pick what she/he considers the most reliable information based on her/his trust requirements. With the introduction of web services, the problem is further exacerbated as users have to come up with a new set of requirements for trusting web services and web services themselves require a more automated way of trusting each other. Apart from inaccurate or outdated information, we also need to anticipate Semantic Web Spam (SWAM) — where spammers publish false facts and scams to deliberately mislead users. This workshop is interested in all aspects of enabling trust on the web.”

CASCON 2005 Keynote – Rob Clyde @ Symantec

October 18th, 2005, by Pranam Kolari, posted in Conferences, CS, GENERAL, Policy, Security

Rob Clyde, Vice President of Technology, Office of the CTO @ Symantec Corporation presented his keynote today morning. Along with the usual security stuff he reported on some interesting statistics —

Clyde

  • Phishing is becoming an increasing threat as 3 to 4% of users respond to such mails — much higher than traditional e-mail spam.
  • In the first half of 2005 phishing increased from 2.99 Million e-mails/day to 5.7 Million e-mails/day.
  • 31% of online consumers are buying less due to increased web security threat.
  • US leads in the number of hacked machine reports followed closely by Germany.
  • Broadband penetration is actually increasing security threats. Many personal machines are now vulnerable to hackers using them as web bots for DOS attacks.
  • DOS Attacks are now a business. Such attacks are now available for as low as US $300. Where?

Some other interesting comments ..

  • The increasing speed at which worms propogate are now demanding better use of proactive measures.
  • In the absence of such measures Akamai and it’s expandable bandwith pipes are the only solution against DOS Attacks. Looks like more revenues to Akamai in the days to come! Maybe Akamai’s stock is in for a ride.

Finally, and of importance to us — Symantec is now working on compating web (and blog) spam. They see this as being one of the next big security threat.

AAAI-05 Word Search Puzzle

July 7th, 2005, by mayfield, posted in AI, Conferences, GENERAL

Just when you thought you might actually have to pay attention to that talk at AAAI (you know the one), along comes the AAAI 2005 Word Search Puzzle. It’s new, it’s improved, it’s old-fashioned, and ‘AI’ is particularly easy to find (more than once if you so desire).

As with each of the previous puzzles (such as this one, this one, or even this one), the terms (generously provided by Tim “Rack-Mount” Finin) were interlinked using a heuristic best-first search that favors shared letters, small diagrams and a uniform distribution of word directions. The empty cells were filled using a character 4-gram language model derived from the entries themselves.
