RecSys'09: Third ACM Conference on Recommender Systems Call for Paper


We are pleased to invite you once again to participate in the premier annual event on research and applications of recommendation technologies, the Third ACM Conference on Recommender Systems. The previous conferences in Minneapolis and Lausanne have been distinguished by a strong level of interaction between practitioners and researchers in the sharing of ideas, problems and solutions, and the 2009 conference will continue in this tradition. The fully-refereed proceedings will be published by the ACM and, like past RecSys proceedings, are expected to be widely read and cited.


The technical program will celebrate the diversity of research in and applications of recommender systems with refereed and invited presentations, keynote talks and posters.


The first day of the conference will be devoted to tutorials in which top practitioners and researchers share their expertise and latest results. The tutorials at the 2008 conference were highly-attended. Look for the Call for Tutorials announcement on the website, or send email to if you are interested in presenting a tutorial.


To reflect the diversity of research in recommender systems and to give additional venues for the presentation of research, the conference will feature workshops for the first time.

    Topic Detection and Tracking


    Monday, April 21, 2008

    Content-based Image Retreival(CBIR)

    Most image retrieval today rely on metadata such as captions or keywords, which actually is text-based retrieval.

    "Content-based" means that the search will analyze the actual contents of the image. The term 'content' in this context might refer to colors, shapes, textures, or any other information that can be derived from the image itself.

    Potential uses for CBIR include:
    • Art collections
    • Photograph archives
    • Retail catalogs
    • Medical diagnosis
    • Crime prevention
    • The military
    • Intellectual property
    • Architectural and engineering design
    • Geographical information and remote sensing systems

    Query techniques:
    • Query by example. An example image is provided to the CBIR system, and the underlying search engine returns imags sharing common elements with the provided example.This query technique removes the difficulties that can arise when trying to describe images with words.
    • Semantic retrieval. The user makes a request like "find pictures of dogs" or even "find pictures of Abraham Lincoln", which is quite difficult for computer to perform. Current CBIR systems generaly make use of lower-level features like textures, color, and shape, although some systems take advantage of very common higher-level features like faces. Not every CBIR system is generic. Some systems are designed for a specific domain.

    Content comparison techniques:
    • Color. It retrieves images based on color similarity, e.g. by computing a color histogram for each image that identifies the proportion of pixels within an image holding specific values. This is one of the most widely used techniques because it does not depend on image size or orientation.
    • Texture. It look for visual patterns in images and how they are spatially defined. Textures are represented by texels which are then placed into a number of sets, depending on how many textures are detected in the image. These sets not only define the texture, but also where in the image the texture is located.
    • Shape. It refers to the shape of a particular region that is being sought out. Shapes will often be determiend first applying segmentation or edge detection to an image.

    Lustre File System

    What is Lustre?

    Lustre is a scalable, secure, robust, highly-available cluster file system. It is designed, developed and maintained by Sun Microsystems, Inc.

    The central goal is the development of a next-generation cluster file system which can serve clusters with 10,000's of nodes, provide petabytes of storage, and move 100's of GB/sec with state-of-the-art security and management infrastructure.

    Lustre runs on many of the largest Linux clusters in the world, and is included by Suns's partners as a core component of their cluster offering (examples include HP StorageWorks SFS, and the Cray XT3 and XD1 supercomputers). Today's users have also demonstrated that Lustre scales down as well as it scales up, and runs in production on clusters as small as 4 and as large as 25,000 nodes.

    Hard vs. fuzzy clustering

    "Data clustering is the process of dividing data elements into classes or clusters so that items in the same class are as similar as possible, and items in different classes are as dissimilar as possible. Depending on the nature of the data and the purpose for which clustering is being used, different measures of similarity may be used to place items into classes, where the similarity measure controls how the clusters are formed. Some examples of measures that can be used as in clustering include distance, connectivity, and intensity.

    In hard clustering, data is divided into distinct clusters, where each data element belongs to exactly one cluster. In fuzzy clustering, data elements can belong to more than one cluster, and associated with each element is a set of membership levels. These indicate the strength of the association between that data element and a particular cluster. Fuzzy clustering is a process of assigning these membership levels, and then using them to assign data elements to one or more clusters." - wikipedia

    Comparing with hard clustering, fuzzy clustering has more applications due to its flexibility and the nature of decision making.
