The authors give a brief account of their combined 7+ years in multimedia standardization, namely in the MPEG arena. They discuss specifics on musical content description in MPEG-7 Audio and other items relevant to Music Information Retrieval among the MPEG-7 Multimedia Description Schemes. In the presentation, they will give a historical overview of the MPEG-7 standard, its motivations, and wh...

The information retrieval systems that are present nowadays are mainly based on full text matching of keywords or topic based classification. This matching of keywords often returns a large number of irrelevant information and this does not meet the user’s query requirement. In order to solve this problem and to enhance the search using semantic environment, a technique named ontology is implem...

Taxonomic identification systems based on character-taxon matrices usually perform better than rulebased systems. Also, matrix data can be used for other purposes, such as description writing, classification, and information retrieval. Most matrix-based systems do not use probabilities, but this is seldom a significant limitation.

Web search over peer-to-peer (P2P) networks shows promise to become an alternative to the state-of-the-art search engines since P2P overlays offer means for decentralized search across widely-distributed document collections. However, the design of effective techniques for P2P indexing and retrieval raises a number of technical challenges due to potentially unscalable resource (e.g. bandwidth, ...

Web browsing involves two tasks: finding the right web page and then making sense of its content. So far, research has focused on supporting the task of finding web resources through ‘standard’ information retrieval mechanisms, or semantics-enhanced search. Much less attention has been paid to the second problem. In this paper we describe Magpie, a tool which supports the interpretation of web ...

This paper introduces a new method to analyse the image texture and to index the image database. We present a new strategy to reduce the computational time to extract image features with high retrieval accuracy. We also propose a method to reduce the image feature dimension, so any robust indexing methods can be used. By weighting the extracted image features, a system may perceive the image co...

It is a pivotal task how to organize and manage resources for Grid researchs and applications.This paper first proposes Grid resource management strategies by employing τ -parameter fuzzy concept lattice and fuzzy concept trie and combines FCA theory with Grid resource management technology.The formal concept definitions of Grid and resource are given and τ -parameter fuzzy concept lattice mode...

We propose an approach to Distributed Information Retrieval based on the periodic and incremental centralisation of full-text indices of widely dispersed and autonomously managed content sources. Inspired by the success of the Open Archive Initiative’s protocol for metadata harvesting, the approach occupies middle ground between: (i) the crawling of content, and (ii) the distribution of retriev...

Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The “linked data” approach, which mandates that resource URIs should be de-referenced and yield metadata about the resource, helps but is only a partial solution. We present Sindice, a lookup index over resources crawled on the Seman...
