The bag of words representation (BoW), which is widely used in information retrieval (IR), represents documents and queries as word lists that do not express anything about context information. When we look for information, we find that not everything is explicitly stated in a document, so context information is needed to understand its content. This paper proposes the use of bag of concepts (B...

The design of efficient indexing structures is central to the performances of very large databases such as the web collections. Within the SPIRIT framework the challenge is to adapt ideas from the well-researched topics of text based information retrieval and geographical information systems for a spatially aware search engine. This document reports on the existing methods for both these areas ...

Information Retrieval (IR) systems require input corpora to be indexed. The advent of terabyte-scale Web corpora has reinvigorated the need for efficient indexing. In this work, we investigate distributed indexing paradigms, in particular within the auspices of the MapReduce programming framework. In particular, we describe two indexing approaches based on the original MapReduce paper, and comp...

the main idea of this survey was to gather the data related to malaysian open access journals (oajs) with respect to their subject, host organization, indexing, full text availability and language during 2005-2012. malaysian journals were selected for this survey because malaysia is currently one of the successful countries in science and technology among other islamic countries. data gathering...

The utilization of clouds in accessing of remote resources has evolved tremendous advantages like parallel execution, virtualization and supremacy of processing. Rather to filter queried information through single remote server is many times better to process it from a centralized cloud. Present architecture of information indexing and filtering mechanism is far away from cloud computing techno...

This proposal presents the methodology of indexing with images suggested by De Brito and Caribé (2015). The imagetic model is used as a compatible mechanism with FRSAD for a global information share and use of subject data, both within the library sector and beyond. The conceptual model of imagetic indexing shows how images are related to topics and ‘key-images’ are interpreted as nomens to imp...

Abstract—One of the serious threats to cyberspace is the Bot networks or Botnets. Bots are malicious software that acts as a network and allows hackers to remotely manage and control infected computer victims. Given the fact that DNS is one of the most common protocols in the network and is essential for the proper functioning of the network, it is very useful for monitoring, detecting and redu...
