We have proposed a neural network model that stores the incoming information after orthogonalizing it in the same manner as vectors are orthogonalized. The scheme enables the brain to compare a new informational system with those in the memory and store its similarities and differences with the old memories in an economical manner. This allows the brain to have an enormous capacity and yet the ...
Background and aim: The aim of this study was to identify the factors affecting on students' performance in information retrieval based on fuzzy logic method compared to traditional method. Materials and methods: This survey-descriptive study was performed using quantitative approach. The research population was 34 PhD students, and the researcher-made questionnaire was used. Data were analyzed...
This paper proposes an identity management system model which will ensure secure storage and retrieval of the IDs information in the scalable identity database. The proposed model uses the distributed database technology for information storage and retrieval to make the system more reliable. The IDs information storage is secured by using cryptography mechanism of data conversion in the identit...

this study investigates the effect of teacher’s repetition as an input enhancement technique in explicit teaching of vocabulary items on efl learners’ later retrieval. to this end, 66 persian speaking english learners, aged 18 - 29, homogenized through a standard proficiency test (opt), were chosen and put into two experimental and control groups, each 33 learners. general service list (gsl), a...
Abstract Background and Aim: The socio-cognitive theory introduced in information science by Horland and Alberchtsen. The socio-cognitive view turns the traditional cognitive program upside down. The socio-cognitive theory emphasizes on different cultural and social structures of users. Hence, the aim of the article is to explain the role of socio - cognitive theory in information retrieval (I...
Using the language-specific behavior in information retrieval systems can improve the quality of the retrieved results significantly. Part of the word that remains after removing its affixes is called stem. Stemming process can be used for improving the relevancy of the results in information retrieval system. Different morphological variants of words (plural, past tense…) will be mapped into t...
Information retrieval (IR) refers to the processes and activities involved in obtaining information from a particular source. Information organization and representation are key components of IR. This book, written by Heting Chu, a professor at the Palmer School of Information Science at Long Island University, aims to provide a comprehensive overview of key concepts and major developments in t...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
This article proposes the introduction of emerging technologies based on semantics, combined with multi-agent systems, information retrieval techniques and reasoning processes, to automate and facilitate the processes of identification, extraction, storage and retrieval of personal graduate information associated with an educational institution, oriented to obtain accreditation. Thereby impleme...
