Olena Medelyan is a grad student who has just started on a Google-funded PhD scholarship, looking at keyphrase extraction using lexical and linguistic techniques. Keyphrases are widely used in information retrieval as a brief but precise summary of documents. They are usually selected by professional human indexers. The more consistent the indexers are with each other, the higher the retrieval ...

Google Tech Talks February 2, 2007 ABSTRACT We present a new approach for semantic image analysis that combines knowledge of human perception with an understanding of signal characteristics to segment natural scenes into perceptually uniform regions, and then uses the region statistics to extract semantic information that can be used for intelligent and efficient image organization and retrieva...

Google Tech Talks February 12, 2007 ABSTRACT Density modelling in high dimensions is a very difficult problem. Traditional approaches, such as mixtures of Gaussians, typically fail to capture the structure of data sets in high dimensional spaces. In this talk we will argue that for many data sets of interest, the data can be represented as a lower dimensional manifold immersed in the higher dim...

Kris Rasmussen and Andy Holt from Competitious will be sharing their experience using RoR in a production environment in a new startup. In addition, they'll explain some of the many advantages Rails has for companies like theirs and smaller teams, as well as some of the disadvantages and gotchas of production Rails apps. Finally, they'll describe their architecture and cover some unique...

Google Tech Talks March 5, 2007 ABSTRACT Web-based replacements for spreadsheets and simple forms By Dave Raggett, W3C Fellow and Principal Researcher at Volantis Systems. The ability to collect data from users and to submit it to servers has become a very important part of the Web. Forms are often supplemented by Web page scripts that enable the data to be checked as the user is filling out th...

Google Video tech Talks February 27, 2007 ABSTRACT This paper evaluates the suitability of the MapReduce model for multi-core and multi-processor systems. MapReduce was created by Google for application development on data-centers with thousands of servers. It allows programmers to write functional-style code that is automatically parallelized and scheduled in a distributed system. We describe ...

Google Tech Talks February 21, 2007 ABSTRACT Getting initialization right is an important part of programming. Over the years, this has led to a mess of language facilities and techniques. This talk describes how C++0x (most likely) will address two issues: how to get a uniform syntax and semantics for all initialization and how to allow initialization by general lists. Obviously, people will w...

Google Tech Talks February 21,2007 ABSTRACT: With the advent of worms, passive malcode, and sophisticated attackers, the "Big Firewall" model of security has failed. To build robust commercial networks in the future, security will need to move into the LAN infrastructure. The LAN vantage point requires a nearly two-order-of-magnitude cost/performance improvement over conventional netw...

Google Tech Talks February 21, 2007 ABSTRACT: Concepts are a major addition to C++0x that make templates more robust, more powerful, and easier to write and use. At their most basic level, concepts provide a type system for templates. Using concepts, the C++ compiler is able to detect errors in the definition and use of templates before they are instantiated. One immediately obvious benefit of ...

Google Tech Talks February 21, 2007 ABSTRACT The Python language, while object-oriented, is fundamentally different from both C++ and Java. The dynamic and introspective nature of Python allow for language mechanics unlike that of static languages. This talk aims to enlighten programmers new to Python about these fundamentals, the language mechanics that flow from them and how to effectively pu...
