The First Mid-Atlantic Student Colloquium on Speech, Language and Learning is a one-day event to be held at the Johns Hopkins University in Baltimore on Friday, 23 September 2011. Its goal is to bring together students taking computational approaches to speech, language, and learning, so that they can introduce their research to the local student community, give and receive feedback, and engage each other in collaborative discussion. Attendance is open to all and free but space is limited, so online registration is requested by September 16. The program runs from 10:00am to 5:00pm and will include oral presentations, poster sessions, and breakout sessions.

The First Baltimore Hackathon will take place on Friday and Saturday, November 19-20, 2010 at Beehive Baltimore, 2400 Boston St, on the 3rd floor of the Emerging Technology Center.

Come to build a hardware or software project — from idea to prototype — in a weekend either individually or as part of a team! While you are hacking, you’ll enjoy free food and coffee and be eligible to win prizes and awards! If you are interested, sign up and use the Baltimore Hackathon wiki to share ideas and build a team or to list yourself as available to join an existing team.

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

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.

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.

Organizers:

• Lalana Kagal, Massachusetts Institute of Technology
• Ora Lassila, Nokia
• Tim Finin, University of Maryland, Baltimore County

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:

• POWERSET – Natural Language and the Semantic Web, Keynote talk by Barney Pell, Powerset, Inc.
• How I was right even when I was wrong, Keynote talk by Chris Welty, IBM
• Automatic Techniques for Extracting Semantic Data (from text and media), Tutorial by Fabio Ciravegna, University of Sheffield

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 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.

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.”

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 –

• 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.

Paper presentations at CASCON 2005 started today. This annual event is sponsored by IBM Toronto Labs and IBM CAS in co-operation with National Research Council Canada. Initial impressions — a very good place to demonstrate/present work relevant to IBM.

CASCON 2005, the 15th annual international conference hosted by the IBM Centers for Advanced Studies, is the premiere computer science and software engineering conference in Canada. CASCON is an excellent venue for exchanging ideas, showcasing results, experiences and tools, and networking with researchers and practitioners from academia, industry, and government.

Check out CASCON blog for information as it happens.

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.

The W3C will hold a workshop on Frameworks for Semantics in Web Services 9-10 June 9-10, 2005 at the Digital Enterprise Research Institute (DERI) in Innsbruck, Austria. Position papers must be submitted to obtain an invitation to participate and are due by 22 APril 2005.

A one-day Workshop on Ambient Intelligence – Agents for Ubiquitous Environments will be held in 25 or 26 July 2005 in Ultrecht, The Netherlands in conjunction with the 2005 Conference on Autonomous Agents and Multiagent Systems. Submitted papers are due 14 March, 2005.

The merging of virtual environments, mobile communication and sensors, allows the emergence of a new vision: Ambient Intelligence, a pervasive and unobtrusive intelligence in the surrounding environment supporting the activities and interactions of the users. Ambient intelligence appears poised to cause remarkable changes in the way
people live. With digital information, the ease of interaction between humans and computers can be greatly increased by broadening the interface media available and allowing mobile and portable communication to become free of inhibiting wires and stationary units. The result of ambient intelligence is ultimately a more empowered computer with the benefits of added convenience, time and cost savings, and possibilities for increased safety, security, and entertainment. This technology has the potential to significantly impact business and government processes, as well as private life.

Ambient Intelligence represents a vision of the future where we shall be surrounded by electronic environments, sensitive and responsive to people. Ambient intelligence technologies are expected to combine concepts of ubiquitous computing and intelligent systems putting humans in the centre of technological developments. Ambient
Intelligence emphasises greater user-friendliness, more efficient services support, user-empowerment, and support for human interactions. Software Agent (SA) technology is promising in this field and thus, should have a major role in Ambient Intelligence development due to SA characteristics such as autonomy and mobility. For instance, a user could launch an agent from his mobile phone and disconnect itself from the network. Its agent roams the net
of providers and afterwards submits its findings to user through SMS messages.
