Web Structure Mining: Exploring Hyperlinks and Algorithms for Information Retrieval

This paper focus on the Hyperlink analysis, the algorithms used for link analysis, compare those algorithms and the role of hyperlink analysis in Web searching. In the hyperlink analysis, the number of incoming links to a page and the number of outgoing links from that page will be analyzed and the reliability of the linking will be analyzed. Authorities and Hubs concept of Web pages will be explored. The different algorithms used for Link analysis like PageRank, HITS (Hyperlink-Induced Topic Search) and other algorithms will be discussed and compared. The formula used by those algorithms will be explored

HYPERLINK NETWORK SYSTEM AND IMAGE OF GLOBAL CITIES: WEBPAGES AND THEIR CONTENTS

A distinctive trend of globalization research is a conceptual expansion that mirrors the penetration of globalization in various aspects of life. The World Wide Web has become the ultimate platform to create and disseminate information in this era of globalization. Although the importance of web-based information is widely acknowledged, the use of this information in global city research is not significant yet. Therefore, the purpose of this research is to extend the concept of globalization to the efficiency of information networks and the thematic dimensionality of the conveyed images from webpages. To this end, 264 global and globalizing cities are selected. The city hyperlink networks are constructed from the web crawling results of each city, and hyperlink network analysis measures the effectiveness of these hyperlink networks. The textual contents are also extracted from the crawled webpages, and the thematic dimensionality of the textual contents is measured by quantified content analysis and multidimensional scaling. The efficiency of the hyperlink network in information flow is confirmed to be a new consideration that shapes the globality of cities. The cities with high efficiency of connections have faster and easier access, which means better structure for city image formation. Specifically, social networking websites are the center of this information flow. This means that social interactions on the Web play a crucial role to form the images of cities. Apart from the positivity and the negativity of the city image, the dimensionality of cities on the thematic space denotes how they are expressed, discussed, and shared on the Web. The image status based on dimensions of globalization is an important starting point to city branding. It is concluded that a research framework handling information networks and images simultaneously deepens the understanding of how the structure and the contents on the Web affect the formation and maintenance of global city networks. Overall, this research demonstrates the usefulness of information networks and images of cities on the Web to overcome data inconsistency and scarcity in global city research

Indonesian Tourism on Australian Websites: Mapping Major Issues with Online Field Theory

Australia is very important to Indonesia’s tourism recovery strategies after the COVID-19 pandemic. This study examines tourism issues in Indonesia as represented by Australian websites. By mapping actors and issue networks in Australian sites, this study identified the status and behavior of actors in online networks. This study applies a Bourdieusian framework adapted to an online setting called online field theory. Applying web data to study the behavior of actors or organizations, this study combined the hyperlink network and content analysis. It has been found that tourism policies and tourism impact on the economy in Indonesia is a major concern for Australian actors. The web narratives indicate that the COVID-19 pandemic contextualizes the emergence of major issues and prominent actors dealing with the issues. A map of the hyperlink network confirmed the structure of the fields in which privileged actors in Australia, such as the government and the media, are more central in framing and diffusing the issues. It is argued that issue formation and adoption on the web reflect multiple Australian interests to Indonesia’s tourism
