The traditional notion of topical relevance has allowed much useful work to be done in the evaluation of retrieval systems, but has limltations for complete assessment of retrieval systems. While topical relevance can be effective In evaluating various lndexing and retrieval approaches, It is ineffective for measuring the impact that systems have on users. An alternative is to use a more situat...

Non-interactive evaluations of Information Retrieval (IR) systems do not model many of the contextual factors that influence real users’ information seeking. As such, they may give overlysimplified grounds for IR system comparison. This paper advocates the use of rich contextual simulations (i.e., simulations of user behavior and the factors that influence it) to extend and enhance the non-inte...

The quality of reusable elements must be rigorously monitored and guaranteed before they can be reused, this is known as Certification. High levels of certification of these elements generate trust and stimulate reuse. In this paper we describe the development of a tool based on quality oriented reuse strategies. To this end, we take as starting point an ontology that rigorously correlates the ...

The ontology development area has received some attention over the years. Methodologies focusing in diverse aspects of ontology development have emerged. Some of these methodologies are consolidated, presenting phases and activities. However, existing methodologies do not fully consider the ontology integration process. Therefore, based on METHONTOLOGY and a methodology for integrating ontologi...

in this research, effect of vermicompost and plant growth promoting rhizobacteria (pgpr) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at karaj research institute of forest and rangelands. experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...

This paper provides a detailed theoretical analysis of methods to approximate the solutions of high-dimensional (> 10) linear Bayesian problems. An optimal low-rank projection that maximizes the information content of the Bayesian inversion is proposed and efficiently constructed using a scalable randomized SVD algorithm. Useful optimality results are established for the associated posterior er...

Animated graph gives some good impressions in presenting information. However, not many people are able to produce it because the process of generating an animated graph requires some technical skills. This work presents Content Management System with Animated Graph (CMS-AG). It is a webbased system enabling users to produce an effective and interactive graphical report in a short time period. ...

Web technology in an instructional environment is primarily dedicated to distributing course materials to supplement traditional classroom learning. It also uses designed intelligence to adapt to learners’ specific needs. The main purposes of this study were to construct and determine the efficiency of adaptive web-based instruction for LIS students. The web-based content was designed to adapt ...
