    Abstract
    A novel idea of media agent is briefly presented, which can automatically build a personalized semantic index of Web media objects for each particular user. Because the Web is a rich source of multimedia data and the text content on the Web pages is usually semantically related to those media objects on the same pages, the media agent can automatically collect the URLs and related text, and then build the index of the multimedia data, on behalf of the user whenever and wherever she accesses these multimedia data or their container Web pages. Moreover, the media agent can also use an off-line crawler to build the index for those multimedia objects that are relevant to the user's favorites but have not accessed by the user yet. When the user wants to find these multimedia data once again, the semantic index facilitates text-based search for her.

    Abstract
    Indexing remains one of the most popular tools provided by digital libraries to help users identify and understand the characteristics of the information they need. Despite extensive studies of the problem of automatic index construction for text-based digital libraries, the construction of multimedia digital libraries continues to represent a challenge, because multimedia objects usually lack sufficient text information to ensure reliable index learning. This research attempts to tackle the problem of automatic index construction for multimedia objects by employing Web usage logs and limited keywords pertaining to multimedia objects. The tests of two proposed algorithms use two different data sets with different amounts of textual information. Web usage logs offer precious information for building indexes of multimedia digital libraries with limited textual information. The proposed methods generally yield better indexes, especially for the artwork data set.

    Abstract
    A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

    Abstract
    Although classification has been an important aspect of astronomy since stellar spectroscopy in the late nineteenth century, to date no comprehensive classification system has existed for all classes of objects in the universe. Here we present such a system, and lay out its foundational definitions and principles. The system consists of the "Three Kingdoms" of planets, stars and galaxies, eighteen families, and eighty-two classes of objects. Gravitation is the defining organizing principle for the families and classes, and the physical nature of the objects is the defining characteristic of the classes. The system should prove useful for both scientific and pedagogical purposes.

    Abstract
    Wordmanship is a humorous dictionary cum index. Analyzing its structure, considers general aspects of the design of a reference work in relation to its index. Indexers should be consulted at the design stage of reference books, as they may suggest reversal of the primary entries, and the index entries; refine the cross-reference-structure; revise locator notation; and select appropriate typography

    Abstract
    Comments on Douglas Hofstadter's index to his book 'Le ton beau de Marot: in praise of the music of language'. Hofstadter took charge of the book design, typography, typesetting and copy-editing, and also compiled the index which covers 23 pages of 3 columnes and is set in a practically illegible 4-point. Although the index breaks all the rules of indexing, it is a masterly creation showing the author's industry, exhuberance and wit. Summarizes Hofstadter's own remarks on how creating the index gave hin new insights into what his book was essentially about

    Abstract
    In this chapter we describe methodologies for representing information in digital libraries in order to support efficient search and content-based retrieval, and we focus our attention an image repositories. We identify different abstraction levels at which content can be specified. We discuss how simple objects can be defined as connected regions that are homogeneous with respect to pixel-level, feature-level, semantic-level, and metadata-level characteristics. We describe how information can be efficiently represented at these different levels, how a user can specify content, and what mechanisms can be used to perform the search. We present techniques for combining image representation, in particular image compression, with image-processing operators designed for content-based searches. On the one hand this approach makes it possible to extract and index content at database ingestion time even when the data volume is large. On the other hand it allows the system to retrieve simple objects for which definitions are provided at query time and that have not been pre-extracted and preindexed. Simple objects, however, are not sufficient to describe the richness of image content. We rely an the concept of composite object, a collection of simple objects satisfying a set of relations, to specify complex queries. We describe algorithms for retrieving composite objects from image databases. This article is organized as follows. The next section contains an introduction to digital libraries and a description of four application areas. The aspects of compression that are relevant to progressive retrieval are discussed in the section attached. The subsequent section provides a brief introduction to content-based searches, the standard approach to query specification in multimedia databases. Our definition of content in terms of simple and composite objects is contained in the following section. Simple objects can be defined at multiple abstraction levels; fundamental concepts, content-extraction methodologies including progressive techniques, and indexing methods are discussed in the next section. Simple objects can also be defined simultaneously at multiple abstraction levels, and aggregated to form composite objects. The semantics of both types of objects and the techniques required to search for them are the subject of the section after that. The final section contains the conclusions.

    Abstract
    In content based image retrieval systems, it is necessary to find a metric to index shapes of objects of the images. The metric should be unique to each shape, regardless of size and orientation. A similarity measure is also needed which should reflect the perceptual similarity. Chain codes have been used for shape description in earlier research, but chain codes are non invariant to shape size and orientation. Introduces a method to eliminate the inherent non variance of chain codes to obtain unique chain codes for shapes. The shape index is derived from this unique chain code representation. Discusses the shape distance and similarity measures based on the shape index. Indexing and retrieval procedures should be applicable to large image databases
