Abstract

The present paper analyzes the changes that occurred to a set of Web pages related to "informetrics" over a period of 5 years between June 1998 and June 2003. Four times during this time span, in 1998,1999, 2002, and 2003, we monitored previously located pages and searched for new ones related to the topic. Thus, we were able to study the growth of the topic, white analyzing the rates of change and disappearance. The results indicate that modification, disappearance, and resurfacing cannot be ignored when studying the structure and development of the Web.

Abstract

Organizing and providing access to the resources an the Internet has been a problem area in spite of the availability of sophisticated search engines and other Software tools. There have been several attempts to organize the resources an the WWW. Some of them have tried to use traditional library classification schemes such as the Library of Congress Classification, the Dewey Decimal Classification and others. However there is a need to assign proper subject headings to them and present them in a logical or hierarchical sequence to cater to the need for browsing. This paper attempts to describe an experimental system designed to organize and provide access to web documents using a faceted pre-coordinate indexing system based an the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing System of Ranganathan. A prototype software system has been designed to create a database of records specifying Web documents according to the Dublin Core and input a faceted subject heading according to DSIS. Synonymous terms are added to the standard terms in the heading using appropriate symbols. Once the data are entered along with a description and URL of the Web document, the record is stored in the system. More than one faceted subject heading can be assigned to a record depending an the content of the original document. The system stores the surrogates and keeps the faceted subject headings separately after establishing a link. Search is carried out an index entries derived from the faceted subject heading using chain indexing technique. If a single term is input, the system searches for its presence in the faceted subject headings and displays the subject headings in a sorted sequence reflecting an organizing sequence. If the number of retrieved headings is too large (running into more than a page) then the user has the option of entering another search term to be searched in combination. The system searches subject headings already retrieved and look for those containing the second term. The retrieved faceted subject headings can be displayed and browsed. When the relevant subject heading is selected the system displays the records with their URLs. Using the URL the original document an the web can be accessed. The prototype system developed under Windows NT environment using ASP and web server is under rigorous testing. The database and indexes management routines need further development.

Abstract

This article addresses the question of whether the Web can serve as an information source for research. Specifically, it analyzes by way of content analysis the Web pages retrieved by the major search engines on a particular date (June 7, 1998), as a result of the query 'informetrics OR informetric'. In 807 out of the 942 retrieved pages, the search terms were mentioned in the context of information science. Over 70% of the pages contained only indirect information on the topic, in the form of hypertext links and bibliographical references without annotation. The bibliographical references extracted from the Web pages were analyzed, and lists of most productive authors, most cited authors, works, and sources were compiled. The list of reference obtained from the Web was also compared to data retrieved from commercial databases. For most cases, the list of references extracted from the Web outperformed the commercial, bibliographic databases. The results of these comparisons indicate that valuable, freely available data is hidden in the Web waiting to be extracted from the millions of Web pages

Abstract

The World Wide Web Consortium (W3C) has worked well in the rapid establishment of HTML standards but it has been criticized for not assuring compliance and in June 1998 a new organization, the Web Standards Project (WSP) was formed. Membership is free to individuals and at present consists of Web designers and W3C members. Describes the stages in the implementation of standards and focuses on Cascading Style Sheets (CSS). A style sheet is essentially a template that can be used to create a consistent appearance across documents. 'Cascading' means that a single page can use multiple style sheets. Explains how style sheets can replace HTML tags, using the example of fonts, and why CSS is a greater attraction to designers than to Web users. Outlines the current state of the CSS standard and predicts that Web users will be adopting it sooner or later

Abstract

Firstgov is the U.S. federal portal to government information and services. It was conceived by the Clinton administration in June of 2000 and launched in September 2000. A case study of the development of Firstgov indicated that top-level leadership, a small and committed project team, and the very condensed timeframe of the project were factors that contributed to the success of the portal. Another reason cited for the success of the Firstgov development was the U.S. federal information policy environment, a robust and evolving framework creating the climate for electronic government. An unusual feature of the project development was the donation of the Inktomi search engine for three years, an event that further enabled Firstgov to open its door on time and on budget. The portal continues today with funding and resources designed to ensure its future.

Abstract

Social network sites like MySpace are increasingly important environments for expressing and maintaining interpersonal connections, but does online communication exacerbate or ameliorate the known tendency for offline friendships to form between similar people (homophily)? This article reports an exploratory study of the similarity between the reported attributes of pairs of active MySpace Friends based upon a systematic sample of 2,567 members joining on June 18, 2007 and Friends who commented on their profile. The results showed no evidence of gender homophily but significant evidence of homophily for ethnicity, religion, age, country, marital status, attitude towards children, sexual orientation, and reason for joining MySpace. There were also some imbalances: women and the young were disproportionately commenters, and commenters tended to have more Friends than commentees. Overall, it seems that although traditional sources of homophily are thriving in MySpace networks of active public connections, gender homophily has completely disappeared. Finally, the method used has wide potential for investigating and partially tracking homophily in society, providing early warning of socially divisive trends.

Abstract

Recent work by Evans, Cordova, and Sipole (2014) reveals that in the two months leading up to the 2012 election, female House candidates used the social media site Twitter more often than male candidates. Not only did female candidates tweet more often, but they also spent more time attacking their opponents and discussing important issues in American politics. In this article, we examine whether the female winners of those races acted differently than the male winners in the 2012 election, and whether they differed in their tweeting-style during two months in the summer of 2013. Using a hand-coded content analysis of every tweet from each member in the U.S. House of Representatives in June and July of 2013, we show that women differ from their male colleagues in their frequency and type of tweeting, and note some key differences between the period during the election and the period after. This article suggests that context greatly affects representatives' Twitter-style.

Abstract

Organizing and providing access to the resources an the Internet has been a problem area in spite of the availability of sophisticated search engines and other Software tools. There have been several attempts to organize the resources an the World Wide Web. Some of them have tried to use traditional library classification schemes such as the Library of Congress Classification, the Dewey Decimal Classification and others. However there is a need to assign proper subject headings to them and present them in a logical or hierarchical sequence to cater to the need for browsing. This paper attempts to describe an experimental system designed to organize and provide access to web documents using a faceted pre-coordinate indexing system based an the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing system of Ranganathan. A prototype Software System has been designed to create a database of records specifying Web documents according to the Dublin Core and to input a faceted subject heading according to DSIS. Synonymous terms are added to the Standard terms in the heading using appropriate symbols. Once the data are entered along with a description and the URL of the web document, the record is stored in the System. More than one faceted subject heading can be assigned to a record depending an the content of the original document. The System stores the Surrogates and keeps the faceted subject headings separately after establishing a link. The search is carried out an index entries derived from the faceted subject heading using the chain indexing technique. If a single term is Input, the System searches for its presence in the faceted subject headings and displays the subject headings in a sorted sequence reflecting an organizing sequence. If the number of retrieved Keadings is too large (running into more than a page) the user has the option of entering another search term to be searched in combination. The System searches subject headings already retrieved and looks for those containing the second term. The retrieved faceted subject headings can be displayed and browsed. When the relevant subject heading is selected the system displays the records with their URLs. Using the URL, the original document an the web can be accessed. The prototype system developed in a Windows NT environment using ASP and a web server is under rigorous testing. The database and Index management routines need further development.

Abstract

This bibliography contains selected cataloging tools an the Internet. It is divided into seven sections as follows: authority management and subject headings tools; cataloging tools by type of materials; dictionaries, encyclopedias, and place names; listservs and workshops; software and vendors; technical service professional organizations; and journals and newsletters. Resources are arranged in alphabetical order under each topic. Selected cataloging tools are annotated. There is some overlap since a given web site can cover many tools.
