Construction of Metaphorical Maps of Cyberspace Resources Based on Point‐Cluster Feature Generalization

ABSTRACTIn the digital age, the expansion of cyberspace has resulted in increasing complexity, making clear cyberspace visualization crucial for effective analysis and decision‐making. Current cyberspace visualizations are overly complex and fail to accurately reflect node importance. To address the challenge of complex cyberspace visualization, this study introduces the integrated centrality metric (ICM) for constructing a metaphorical map that accurately reflects node importance. The ICM, a novel node centrality measure, demonstrates superior accuracy in identifying key nodes compared to degree centrality (DC), k‐shell centrality (KC), and PageRank values. Through community partitioning and point‐cluster feature generalization, we extract a network's hierarchical structure to intuitively represent its community and backbone topology, and we construct a metaphorical map that offers a clear visualization of cyberspace. Experiments were conducted on four original networks and their extracted backbone networks to identify core nodes. The Jaccard coefficient was calculated considering the results of the three aforementioned centrality measures, ICM, and the SIR model. The results indicate that ICM achieved the best performance in both the original networks and all extracted backbone networks. This demonstrates that ICM can more precisely evaluate node importance, thereby facilitating the construction of metaphorical maps. Moreover, the proposed metaphorical map is more convenient than traditional topological maps for quickly comprehending the complex characteristics of networks.

The method of protecting information resources based on the semiotic model of cyberspace

The subject of research in the article is the processes of ensuring the protection of information resources in the cyber-physical space. The goal is to develop a model for implementing a method of information protection in cyber-physical space. The development is based on a semiotic model of cyberspace. The task is to develop effective strategies for protecting information resources and managing cyber security in cyberspace, taking into account social and perceptual aspects. Used methods: methods of analytical modeling and fuzzy logic. The following results were obtained. It is shown that the complex, multifaceted presentation of information in the network requires a complex approach with the separation of mixed content of information into interconnected levels. A semiotic approach is proposed, which allows for a more in-depth analysis of the interaction between people and technologies, which is especially important for understanding and managing complex information security systems. A six-level model of cyberspace was developed with a method of assessing the level of security for each of the levels of the developed model, and an integral indicator of potential threats to the owners of network information resources was proposed. The developed model was verified. The developed semiotic model of cyberspace and the integrated indicator of potential threats make it possible to improve the monitoring and management of cyber security of the owners of network information resources by taking into account various factors, including taking into account social and perceptual aspects, which is a key factor for the development of effective strategies for the protection of information resources in cyberspace.

A community partitioning algorithm for cyberspace

Community partitioning is an effective technique for cyberspace mapping. However, existing community partitioning algorithm only uses the topological structure of the network to divide the community and disregards factors such as real hierarchy, overlap, and directionality of information transmission between communities in cyberspace. Consequently, the traditional community division algorithm is not suitable for dividing cyberspace resources effectively. Based on cyberspace community structure characteristics, this study introduces an algorithm that combines an improved local fitness maximization (LFM) algorithm with the PageRank (PR) algorithm for community partitioning on cyberspace resources, called PR-LFM. First, seed nodes are determined using degree centrality, followed by local community expansion. Nodes belonging to multiple communities undergo further partitioning so that they are retained in the community where they are most important, thus preserving the community’s original structure. The experimental data demonstrate good results in the resource division of cyberspace.

Cross-domain entity identity association analysis and prediction based on representation learning

Cross-domain identity association of network entities is a significant research challenge and a vital issue of practical value in relationship discovery and service recommendation between things in the Internet of things, cyberspace resources surveying mapping, threat tracking, and intelligent recommendation. This task usually adds additional difficulty to the research in practical applications due to the need to link across multiple platforms. The existing entity identity association methods in cross-domain networks mainly use the attribute information, generated content, and network structure information of network user entities but do not fully use the inherent strong positioning characteristics of active nodes in the network. In this article, we analyzed the structural characteristics of existing relational networks. We found that the hub node has the role of identity association positioning, and the importance of identity association reflected by different nodes is different. Moreover, we creatively designed a network representation learning method. We proposed a supervised learning identity association model combined with a representation learning method. Experiments on the public data set show that using the identity association method proposed in this article, the ranking accuracy of user entity association similarity is about 30% and 25% higher than the existing two typical methods.

US-China Confrontation in Cyber Security

This study presents the research results of the activities of the United States and China as the major global competitors in the field of cybersecurity. We have established the nature and trends of the confrontation, explored the goals and means of cyber influences in the confrontation between two states in this area, and identified directions for the development of the competition between the United States and China in the field of cybersecurity. Today, the United States and China are the world leaders in cyberspace and the information (cyber) security sector. The United States remains the undisputed world leader in cybersecurity, but China is rapidly closing the gap, relying on the strong potential of human and economic resources in cyberspace. From the beginning of the second decade of the XXI century. countries have been accusing each other of cyberattacks for economic purposes and cyber espionage. The United States has pointed to the People's Liberation Army's (PLA) leading role in organizing cyberattacks, and China has made similar allegations against the US intelligence. Despite attempts to reconcile policies in this area, tensions between the United States and China over cyber-building are growing. And since the beginning of the 2020s, politically motivated influences on information systems have become the target of cyberattacks. The United States notes a change in China's cyberattack strategy from regular cyber espionage to prosecuting political and security goals. Additionally, systematic control over the sources of cyber threats has been transferred from the PLA to the security structures of China. China also accuses the United States of using cyber influences to increase world hegemony and using cyber threats in the arms race. Beijing makes these statements from the standpoint of its own “multipolar” world strategy, which is threatened by the activities of the Joe Biden administration, aimed at consolidating Western countries in the face of cyber threats from China. The field of cybersecurity in US-China relations is becoming increasingly important in terms of the security strategies of these two world leaders. Each of them uses cyber tools as a tool of cyber influence, as well as a tool for strategic communication at the level of relations with strategic partners. Therefore, these issues will become increasingly important in terms of research interests, in particular the implementation of foreign policy interests in relations with these countries.

Libraries in the information age

Purpose– The purpose of this paper is to measure the competencies of libraries in Nigerian universities, identify constraints to their performance and recommend infrastructures and competencies required. Institutional accreditation has compelled academic libraries in Nigerian to improve their quality, competencies and performances for accountability.Design/methodology/approach– A questionnaire was the main instrument for data collection. The population of the study was all the university librarians in the 89 universities in Nigeria that the author selected from federal, state and private universities. Of the 81 sets of questionnaires emailed, 49 were returned, which represents a 60.5 per cent response rate and provides the working population of the study. Data were analysed using frequency tables, simple percentages and bar charts.Findings– The results indicate that academic libraries and librarians in Nigeria are competent in three key areas – educational roles, professional development and research. However, they are not very effective in the provision and use of library resources in cyberspace, adequate funding, collection development and information technology skills. The main constraints are: poor Internet penetration, low bandwidth, unreliable power supply and weak Internet proficiency. This paper suggests that adequate funding, benchmark performance and multi-skilling can serve as strategies against these constraints in developing regions.Practical implications– This study contributes to library staff assessment because it links strategic objectives to performance measures and associated long-term targets. It broadens issues which affect sustainable performance in academic libraries in Nigeria, as well as in Africa and other developing countries.Originality/value– While performance measurement is well established in developed countries, it is less or not so well established in Nigeria and other developing countries. The current research seeks to develop a performance measurement framework for academic libraries that is testable and expandable to Nigeria and the whole African context.

Mining sensor data in cyber-physical systems

A Cyber-Physical System (CPS) integrates physical devices (i.e., sensors) with cyber (i.e., informational) components to form a context sensitive system that responds intelligently to dynamic changes in real-world situations. Such a system has wide applications in the scenarios of traffic control, battlefield surveillance, environmental monitoring, and so on. A core element of CPS is the collection and assessment of information from noisy, dynamic, and uncertain physical environments integrated with many types of cyber-space resources. The potential of this integration is unbounded. To achieve this potential the raw data acquired from the physical world must be transformed into useable knowledge in real-time. Therefore, CPS brings a new dimension to knowledge discovery because of the emerging synergism of the physical and the cyber. The various properties of the physical world must be addressed in information management and knowledge discovery. This paper discusses the problems of mining sensor data in CPS: With a large number of wireless sensors deployed in a designated area, the task is real time detection of intruders that enter the area based on noisy sensor data. The framework of IntruMine is introduced to discover intruders from untrustworthy sensor data. IntruMine first analyzes the trustworthiness of sensor data, then detects the intruders' locations, and verifies the detections based on a graph model of the relationships between sensors and intruders.

Internet Governance in a Multipolar World: Challenging American Hegemony

This article traces the evolution of Internet governance, beginning with the earliest trans-Atlantic Internet ‘community’ associations that formed in the 1970s, up to and including the present mosaic of semi-private ‘self-regulating’ agencies headquartered mostly in the US. The effectiveness of the current system of Internet governance, based in large measure on US-sponsored bodies such as the Internet Corporation of Assigned Names and Numbers (ICANN), is assessed and contrasted with an emerging international paradigm that seeks greater cross-border harmonisation and multilateral oversight of cyberspace resources. Political disputes arising amongst governments and other interested stakeholders concerning allegations of American regulatory unilateralism are examined. Fuelled in part by a digital divide between the technological haves and have-nots, the battle for the heart and soul of the Internet has reached fever pitch, without any definitive prospects for achieving a global consensus. Special emphasis is placed on emerging US–EU policy differences, as well as divergent North–South positions within the UN-sponsored Working Group on Internet Governance and related conferences. Strategies for enhanced international coordination of Internet governance, building on existing organisational structures and processes, are proposed.

A first look at HealthCyberMap medical semantic subject search engine

HealthCyberMap (http://healthcybermap.semanticweb.org) is a Semantic Web project that aims at mapping selected parts of health information resources in cyberspace in novel semantic ways to improve their retrieval and navigation. This paper describes HealthCyberMap semantic subject search engine methodology and early prototype which attempt to overcome the limitations of conventional free text search engines. Explicit concepts in resource metadata map onto a brokering domain ontology (a clinical terminology or classification) allowing a Semantic Web search engine to infer implicit meanings (synonyms and semantic relationships) not directly mentioned in either the resource or its metadata. Similarly, user queries would map to the same ontology allowing the search engine to infer the implicit semantics of user queries and use them to optimise retrieval. Related issues of metadata, clinical terminologies and automatic vs. manual indexing of medical Web resources are also discussed, together with future methodological directions, which include the use of a true terminology server as an intelligent broker between user queries and HealthCyberMap pool of resource metadata. A comparative evaluation of the new engine based on relevance metrics is also proposed.

HealthCyberMap: a semantic visual browser of medical Internet resources based on clinical codes and the human body metaphor.

HealthCyberMap (HCM-http://healthcybermap.semanticweb.org) is a web-based service for healthcare professionals and librarians, patients and the public in general that aims at mapping parts of the health information resources in cyberspace in novel ways to improve their retrieval and navigation. HCM adopts a clinical metadata framework built upon a clinical coding ontology for the semantic indexing, classification and browsing of Internet health information resources. A resource metadata base holds information about selected resources. HCM then uses GIS (Geographic Information Systems) spatialization methods to generate interactive navigational cybermaps from the metadata base. These visual cybermaps are based on familiar medical metaphors. HCM cybermaps can be considered as semantically spatialized, ontology-based browsing views of the underlying resource metadata base. Using a clinical coding scheme as a metric for spatialization ('semantic distance') is unique to HCM and is very much suited for the semantic categorization and navigation of Internet health information resources. Clinical codes ensure reliable and unambiguous topical indexing of these resources. HCM also introduces a useful form of cyberspatial analysis for the detection of topical coverage gaps in the resource metadata base using choropleth (shaded) maps of human body systems.

A Community College Researcher in the Internet Age

Abstract Curiosity about a ragtime-era ancestor has led a community college instructor to explore the wealth of resources in cyberspace. With few answers readily available in traditional library sources, one must seek new research angles: e-mail inquiries to libraries, archives, and authorities in the field; online searches through library, special collections, and genealogical databases; and newsgroups and listserv postings. In the process, researcher and community college librarian learn not only how to use technology, but also how to best insure that other institutions, organizations, and individuals honor their requests.

Cyberspatial Cognition and Individual Access to Information: The Behavioral Foundation of Cybergeography

In this paper I will examine individual access to information on the Internet through a cognitive-behavioral perspective. I argue that the objective structure of information resources in cyberspace is not helpful for understanding the experience of individual accessibility in cyberspace. Instead, cyberspatial cognition is crucial in constituting the effective cyber-environment and shaping human cyberspatial behavior. I propose a behavioral model of cyber-accessibility and examine how notions underlying conventional accessibility measures such as impedance and opportunity set can be extended for measuring individual cyber-accessibility. I argue that theories about spatial learning, cognitive mapping, and decision-making behavior are helpful for understanding individual cyberspatial behavior. This suggests that behavioral theories and models may provide a theoretical foundation for cybergeography.

Classification Practice and Implications for Subject Directories of the Chinese Language Web-Based Digital Library

ABSTRACT The availability of an increasingly large number of Chinese language resources in cyberspace underpins the foundation for a global digital library. This study presents a methodology to investigate the classification practice of this digital library by examining more than one hundred Chinese language subject directories. The findings show that the construction of these subject directories does not follow established classification systems that are widely employed in the traditional library cataloging of the Chinese-speaking world. Numerous top-level subject headings have emerged in subject directories due to the lack of uniform subject heading control. However, each subject directory usually entertains 12 to 16 subject categories. Pareto's rule, or the 20/80 rule, may govern the access to the resources of this digital library.
