Information Retrieval System: Concept and Scope MODULE - 5B INFORMATION RETRIEVAL SYSTEM
Information Retrieval System: Concept and Scope MODULE - 5B INFORMATION RETRIEVAL SYSTEM 15 Notes INFORMATION RETRIEVAL SYSTEM: CONCEPT AND SCOPE 15.1 INTRODUCTION Information is communicated or received knowledge concerning a particular fact or circumstance. Retrieval refers to searching through stored information to find information relevant to the task at hand. In view of this, information retrieval (IR) deals with the representation, storage, organization of/and access to information items. Here, types of information items include documents, Web pages, online catalogues, structured records, multimedia objects, etc. Chief goals of the IR are indexing text and searching for useful documents in a collection. Libraries were among the first institutions to adopt IR systems for retrieving information. In this lesson, you will be introduced to the importance, definitions and objectives of information retrieval. You will also study in detail the concept of subject approach to information, process of information retrieval, and indexing languages. 15.2 OBJECTIVES After studying this lesson, you will be able to: define information retrieval; understand the importance and need of information retrieval system; explain the concept of subject approach to information; LIBRARY AND INFORMATION SCIENCE 321 MODULE - 5B Information Retrieval System: Concept and Scope INFORMATION RETRIEVAL SYSTEM illustrate the process of information retrieval; and differentiate between natural, free and controlled indexing languages. 15.3 INFORMATION RETRIEVAL (IR) Notes The term ‘information retrieval’ was coined by Calvin Mooers in 1950. It gained popularity in the research community from 1961 onwards, when computers were introduced for information handling. The term information retrieval was then used to mean retrieval of bibliographic information from stored document databases. -
Introduction to Information Retrieval
DRAFT! © April 1, 2009 Cambridge University Press. Feedback welcome. 1 1 Boolean retrieval The meaning of the term information retrieval can be very broad. Just getting a credit card out of your wallet so that you can type in the card number is a form of information retrieval. However, as an academic field of study, INFORMATION information retrieval might be defined thus: RETRIEVAL Information retrieval (IR) is finding material (usually documents) of an unstructured nature (usually text) that satisfies an information need from within large collections (usually stored on computers). As defined in this way, information retrieval used to be an activity that only a few people engaged in: reference librarians, paralegals, and similar pro- fessional searchers. Now the world has changed, and hundreds of millions of people engage in information retrieval every day when they use a web search engine or search their email.1 Information retrieval is fast becoming the dominant form of information access, overtaking traditional database- style searching (the sort that is going on when a clerk says to you: “I’m sorry, I can only look up your order if you can give me your Order ID”). IR can also cover other kinds of data and information problems beyond that specified in the core definition above. The term “unstructured data” refers to data which does not have clear, semantically overt, easy-for-a-computer structure. It is the opposite of structured data, the canonical example of which is a relational database, of the sort companies usually use to main- tain product inventories and personnel records. -
Knowledge Democracy and the Implications to Information Access
The current issue and full text archive of this journal is available at www.emeraldinsight.com/1750-497X.htm Knowledge Knowledge democracy and the democracy implications to information access Ahmad Raza and Hasan Sohaib Murad School of Business and Economics, University of Management and Technology, 37 Lahore, Pakistan Abstract Purpose – The purpose of this paper is to examine the concept of “knowledge democracy,” deploying a pluralistic, and cross disciplinary and humanistic critique. Design/methodology/approach – This is a culturally pluralistic and humanistic interpretation of globally emergent form of learning pedagogy, particularly manifested in e-learning. Findings – This paper explores the concept of knowledge democracy in the context of knowledge and information revolution. It has been argued that knowledge democratization implies freedom and equality to access information and knowledge across cultures and societies, particularly in the context of globalization. It is asserted that a democratization of the notion of knowledge would cause a paradigm shift; the way instruction and education are socially structured in different social systems. The knowledge society provides a new spirit of global sharing of values, acceptance of others and learning to live with divergent worldviews. It is contended that e-learning in particular sets a new global social opportunity to transcend regional, racial and national prejudices. Originality/value – The paper underscores the significance of pluralistic and humanistic perspective on knowledge and e-learning. Keywords Globalization, Epistemology, E-learning, Knowledge management, Information and communication technologies Paper type Conceptual paper Social forms of knowledge Historically, knowledge has been the defining attribute of human species. From the simple hunters of pre-historic times to medieval peasants to modern day information creators; all have sought to understand more deeply the structure of physical and social world. -
Tracking Salience Profiles of Online News Stories
TSPOONS: TRACKING SALIENCE PROFILES OF ONLINE NEWS STORIES A Thesis presented to the Faculty of California Polytechnic State University San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Master of Science in Computer Science by Kimberly Paterson June 2014 c 2014 Kimberly Paterson ALL RIGHTS RESERVED ii COMMITTEE MEMBERSHIP TITLE: TSPOONS: Tracking Salience Profiles Of Online News Stories AUTHOR: Kimberly Paterson DATE SUBMITTED: June 2014 COMMITTEE CHAIR: Professor Alexander Dekhtyar, Ph.D. Department of Computer Science COMMITTEE MEMBER: Assistant Professor Foaad Khosmood, Ph.D. Department of Computer Science COMMITTEE MEMBER: Professor Franz Kurfess, Ph.D. Department of Computer Science iii ABSTRACT TSPOONS: Tracking Salience Profiles Of Online News Stories Kimberly Paterson News space is a relatively nebulous term that describes the general discourse con- cerning events that affect the populace. Past research has focused on qualitatively analyzing news space in an attempt to answer big questions about how the populace relates to the news and how they respond to it. We want to ask when do stories begin? What stories stand out among the noise? In order to answer the big questions about news space, we need to track the course of individual stories in the news. By analyzing the specific articles that comprise stories, we can synthesize the informa- tion gained from several stories to see a more complete picture of the discourse. The individual articles, the groups of articles that become stories, and the overall themes that connect stories together all complete the narrative about what is happening in society. TSPOONS provides a framework for analyzing news stories and answering two main questions: what were the important stories during some time frame and what were the important stories involving some topic. -
Bibliometric Analysis of the Scientific Production of the Information Architecture Related to Libraries
Bibliometric Analysis of the Scientific Production of the Information Architecture Related to Libraries Vitor Taga Danielly Oliveira Inomata Caroline Rodrigues Vaz Mauricio Uriona Maldonado Gregório Varvakis Universidade Federal de Santa Catarina - UFSC, Brasil ARTICLE Abstract Objective. Information architecture is a determinant guiding element for content layout and user navigation. This work aims at identifying and characterizing the scientific production about information architecture related to libraries. Method. In order to achieve the objective, a bibliometric review and a systemic analysis were conducted, the first to identify the most cited articles, the most productive authors in the field, the main journals; and the latter to characterize the debate and results presented in the articles. For the structured literature review, the Proknow-C method was utilized. The search was made in the Web of Science, Scopus and Science Direct databases. Results. One hundred fifteen articles were identified. Three peaks in the number of publications in 2001 (5), 2002 (6) and 2006 (4) were identified. Conclusions. The publications were concentrated in the Social Sciences and Computer Science. The main keywords (Digital libraries, Information architecture and World Wide Web) already contextualize and represent the content of the recovered articles. In relation to content analysis of the articles, a possible convergence in papers aimed towards studies of information architecture and digital libraries is discussed, which is very coherent with the current literature. We point out information architecture makes digital information environments better labelled and facilitates information access. Keywords Bibliometrics; Information architecture; Libraries Análise bibliométrica da produção científica de Arquitetura da Informação relacionados às bibliotecas Resumo Objetivo. -
The Impact of Media Censorship: Evidence from a Field Experiment in China
The Impact of Media Censorship: Evidence from a Field Experiment in China Yuyu Chen David Y. Yang* January 4, 2018 — JOB MARKET PAPER — — CLICK HERE FOR LATEST VERSION — Abstract Media censorship is a hallmark of authoritarian regimes. We conduct a field experiment in China to measure the effects of providing citizens with access to an uncensored Internet. We track subjects’ me- dia consumption, beliefs regarding the media, economic beliefs, political attitudes, and behaviors over 18 months. We find four main results: (i) free access alone does not induce subjects to acquire politically sen- sitive information; (ii) temporary encouragement leads to a persistent increase in acquisition, indicating that demand is not permanently low; (iii) acquisition brings broad, substantial, and persistent changes to knowledge, beliefs, attitudes, and intended behaviors; and (iv) social transmission of information is statis- tically significant but small in magnitude. We calibrate a simple model to show that the combination of low demand for uncensored information and the moderate social transmission means China’s censorship apparatus may remain robust to a large number of citizens receiving access to an uncensored Internet.

This work is made available under the terms of the Creative Commons Attribution 4.0 International License: http://creativecommons.org/licenses/by/4.0 Abstract: In response to open access initiatives, many LIS open access journals have been issued in Arab countries. These journals are not widely known; many DOAJ studies pointed out that there is only one Arabic journal. Giving a wider prospective to LIS open access journals in Arab countries was the objective of this study. Descriptive analysis was used to examine Arabic open access journals' web pages during May and June 2019. Data were collected using a refereed checklist. The study found out that There are 12 open access Journals issued in 8 Arab countries, one of them is ceased since 2013, institutions is the largest publishing body, followed by scientific associations, and 75% of these journals issue in dual formats (paper and digital). Only three journals have open access declaration on its web page, and 4 journals only are covered by indexing services; Dar Al Mandunah covers 75% of these journals. Most full text languages are in Arabic and English, while 80% of journals' web pages are in Arabic. -

Library Philosophy and Practice (e- journal). 5094. https://digitalcommons.unl.edu/libphilprac/5094 The significance of access to information—and the challenges it faces in librarianship Abstract: Access to information is a fundamental value of professional librarianship and library and information science more generally; however, providing such access can be impeded by certain practices of librarianship, as this article describes. We focus on obtaining a better understanding of the extent of censorship practices within information institutions and the effects of restricted access to information on both individuals and communities. This article draws on several theoretical frameworks including regulative and constitutive censorship, information poverty, access as a human right, and the importance of individual autonomy. This research provides a more solid foundation for librarians and other information professionals to apply the value of intellectual freedom to professional practice. Introduction Censorship is the restriction of access to information (Doyle, 2001; Mathiesen, 2008; Oltmann, 2016; Oppenheim & Smith, 2004). -
Obstacles to Information Access and Use in Developing Countries

Uhegbu (2002:62) identifies five: economic, social, environmental, occupational, and infrastructure. Etim (2000) lists seven, including physical infrastructure, technical, and managerial capabilities, among others, though her work focused mainly on scientific and technological information. This paper will discuss obstacles in the following areas: lack of awareness; inaccessibility; information explosion; bibliographic obstacles: environment; poor infrastructure; declining budgets and rising costs; costs for users; staff attitude toward users; and crime. Lack of Awareness Information seekers and users may not know about the resources available. The role of libraries has not always been made clear to information seekers, particularly in developing countries. Ologbonsaiye (1994) identifies and discusses this problem. Some libraries and librarians have concentrated on traditional resources and services, which may in itself be an obstacle to information access and use (Ologbonsaiye, 1994). -
