[boston-lisp] Opportunities at local startup
by Jon S. Anthony 26 Nov '08

26 Nov '08

Hi, I hope this is viewed as an appropriate message, if not please accept my apologies up front. Opportunities at startup for great developers to work on cool problems in online delivered data and document management. We are currently using Lisp for core backend components and are investigating innovative storage and representation technologies to solve extreme scaling issues and interesting problems in capturing and using semantic information. Background in traditional storage (RDBs) and newer technologies (graph stores, et. al.) significant pluses. Also strong background in either Ruby and Java as work involves these as well. Contact Jon Anthony at jon(a)aprigo.com, or reply to this email.

[boston-lisp] Next Boston Lisp Meeting: Monday November 24th 2008 at 1800 at MIT 34-401B

Next Boston Lisp Meeting: Monday November 24th 2008 at 1800 at MIT 34-401B Gregory Marton will give a talk about the meanings of English words as programs. http://fare.livejournal.com/136992.html Gregory will introduce a way of thinking about the meanings of English words as programs (c.f. SHRDLU), cast the problem of language learning as a search through the space of possible programs, and show first steps in learning. Gregory has created a system called Sepia that makes it relatively easy to write small lexicons that implement some semantic theory for a domain. Applications that Gregory and several colleagues have had fun with include: * understanding dates and times and other measures: "next Wednesday" * finding and linking names of people, organizations, places * telling a robot what to do with stuff on a table: "touch the red one" * asking about spatial paths in video: "show people entering the kitchen" * a toy gossip world: "John loves Mary" "Who does not hate Mary?" * a little number theory: "18 is twice the sum of its digits" These applications are inherently brittle, and manual construction gets harder as the application grows. The research goal is to construct new meaning programs with little human input, or with input from non-programmers. Given a problem phrase, Sepia uses standard ways to find similar words that it knows. Its current approach is to take the meanings of those words and makes small changes, looking for a combination that produces the target meaning. Both the system as a whole and the language of semantics are implemented in the GNU/Guile flavor of Scheme. Gregory Marton is a PhD student in computer science at MIT, and this is his dissertation topic. His first language is Hungarian, and since meeting English at age eight, he has wondered about meanings and how to learn language. He has a B.S. in Computer Science with a minor in Linguistics from the University of Maryland, College Park, 1999. * The Lisp Meeting will take place on Monday November 24th 2008 at 1800 (6pm) at MIT, Room 34-401B. As the numbers indicate, this is in Building 34, on the 4th floor. This is the usual location, on 50 Vassar Street, Cambridge.

Anyone who attends is welcome to partake. We appreciate it if you let us know you're coming, and what food taboos you have, so that we can order the right amount of food. Tell us by sending email to boston-lisp-meeting-register at common-lisp.net. We won't send any acknowledgment unless requested; importantly, we'll keep your identity and address confidential and won't communicate any such information to anyone, not even to our sponsors. * * * The previous Boston Lisp Meeting on October 27th had over 30 participants. Tim McNerney gave copious background on the Thinking Machines Corporation and its line of massively parallel computer as an introduction to his work on automated verification of a compiler optimization pass through abstract interpretation. Both the presentation and the following discussion were very lively. We're always looking for more speakers. The call for speakers and all the other details are at http://fare.livejournal.com/120393.html For more information, see our new web site boston-lisp.org.
