Design of Instant Messaging System of Multi-language E-commerce Platform

We propose and study an evolving network model for instant messaging system (IMS) with local-world preferential connections and acquaintance introduction mechanisms, which exist in many physical complex networks especially in IMS evolving network. We put forward the algorithms to generate IMS evolving network model and through simulation results we talk about the topological properties of the IMS evolving network. First of all, degree distribution, clustering coefficient along with average path length are simulated and then the community structure of the model is analyzed. We can draw the conclusion that the degree distribution of IMS evolving network doesnpsilat obey power-law distribution, and this network has a short average path length and a high clustering coefficient. In a word, the simulation result shows that the IMS evolving network is a complex network possessing properties of small-world and clear community structure, but doesnpsilat have scale-free property.

Instant message system (IMS) is becoming increasingly an important means of communication except for traditional mass media. Based on the discussions about the characteristics of IMS message transfer, this paper firstly analyzed the specific characteristics different from traditional tools of communication and puts forward the principles of IMS message transfer. We also analyzed the characters of users in IMS virtual communities, and pointed out how these characters influencing the message transfer and how to control the message transfer correspondingly. We set up a Tobit model of IMS message transfer which includes five factors that may influence the transfer process. Through analyzing the sensitive factors of IMS message transfer, we demonstrate that there are two typical factors influencing IMS message transfer, which are whether a user is "active type" and the relationship types of IMS users. Finally, we proposed some necessary guidelines for enhancing the security of the IMS message transfer.

The goal in this paper is to design and implementation the service agent society mechanism of home network community by using Jini platform. On Ubiquitous smart homes environment, this mechanism can make various services to be used among service agents. Based on the mobility of service agent on the Jini platform and instant messaging system (IMS), the mobile device can receive the real time notify from its federation leader in order to download the necessary service, to remove the unnecessary service, or to update the newly service without reconfiguring the system. Moreover, using the Natural Language Processing, the client is possible to express smoothly the order. Therefore, our proposed agent-based management system for ubiquitous smart homes provides a user-friendly interface, and can make use of add-on functionalities of the IMS such as voice chatting, SMS, and multimedia.

Cet article décrit l’émergence du chat comme dispositif de communication (en analysant la genèse des principaux artefacts) et entreprend de déconstruire l’évidence de son statut de média interactif, d’une part en proposant des « hypothèses fortes » (normatives) sur ce qui fait qu’un média peut être qualifié d’interactif, et d’autre part en montrant que cette forme de communication médiatisée par ordinateur (CMO) s’est articulée de deux façons distinctes. L’une, plutôt conviviale et orientée vers la sociabilité – les « salons » de chat – et l’autre, plus instrumentale et axée sur l’efficacité – les messageries instantanées. L’essor de ces dernières au détriment des espaces de chat « conviviaux » apparaît comme un tournant dans la construction sociale de cette pratique qui reflète la montée de l’individualisme en réseau et nous amène à relativiser l’interactivité du chat en tant que « média social ».

Informal interaction has proven to be useful in supporting collaboration in office and educational environments. Online courses, however, provide limited opportunities for informal interaction, which might put them at a disadvantage when compared with traditional courses. This lack of opportunities could obstruct collaboration among students, a key aspect for successful instruction. To provide students with opportunities for informal interaction, we designed and developed a system named CENTERS. It is an instant messaging and presence awareness system that supports lightweight communications within the group. CENTERS provides awareness of the presence of members of the distributed community and allows them to interact easily and navigate together through the course’s materials, share insights, resolve doubts, and collaborate in course related activities. To evaluate the use of CENTERS in an online learning environment, a study was designed to assess interaction from a socio-academic perspective. Results showed that CENTERS helped reduce the students’ feelings of isolation and facilitated a greater degree of interpersonal interaction within the course participants.

Interpersonal awareness is one person's up-to-the moment knowledge about other group members, while artifact awareness is one person's up-to-the-moment knowledge about other group members' work artifacts; both contribute to fluid group coordination and interaction. Many popular computer-mediated communication systems focus on interpersonal awareness, with artifact awareness being a second-class citizen. To better support artifact awareness in this domain, we leverage the widespread adoption and technical robustness of an unaltered, commercial instant messaging (IM) system. Our main contribution is to treat an artifact, such as a document, as a first-class instant messaging "buddy." Our system, Artifact Buddy, gives each shared artifact an interactive presence on IM, providing awareness cues about its editing status and notifications when new versions are committed, enabling simple version control, and facilitating informal group communication. The group's interactions with and conversation around the artifact are also recorded as part of a persistent conversational history.

Topic detection in group chat has become a promising research due to the widely usage of Instant Messaging (IM) systems. Previous works mainly focus on improving the text similarity between two related messages by utilizing different weighting factors. However, the text similarity of related texts is likely to be zero (or near zero) due to the characteristics of short text messages in group chat. To solve this problem, an innovative topic detection method based on implicit reply which indicates chat messages interact with each other is proposed in this paper. The comparative experiments results on the datasets gathered from QQ groups demonstrate the superiority of the proposed method as compared to the baseline approaches.

We demonstrate the feasibility and experience of having a haptic conversation using WhatsHap: an instant messaging system that delivers speech or text as a sequence of vibrotactile representations of English phonemes to the arm. Previous haptic speech communication studies established feasibility in single-phoneme or word-level encodings, but did not investigate how such communication functions in practice with real-time remote conversation between two individuals. Participants used WhatsHap through the framework of a joint communication task, where they had to converse to achieve a goal, with 88% of all tasks successfully completed. We analyze conversations and user interviews both qualitatively and quantitatively, describing considerations when building a system to mediate conversation haptically, exploring influences on user conversational experience, and offering an account of how linguistic structure changes to accommodate such a mode of communication. In this regard, phoneme-based haptic conversation led to linguistic forms distinct from written and spoken English. Additionally, participants felt that haptic conversation was best suited for information-centered communication in contexts where there is shared knowledge between users.

Primary objective: The current study examined whether cognitive rehabilitation delivered over the Internet was associated with improvements in functioning.Research design: A total of 14 individuals with medically documented traumatic brain injury completed this study. Participants completed 30 sessions of an active calendar acquisition intervention and 30 sessions of a control diary intervention in a cross-over study design for a total of 60 online sessions. All sessions were completed using an instant messaging system via the Internet. Measures of cognitive functioning, ratings of memory and mood and frequency of use of common memory and cognitive compensation techniques were gathered from participants and family members.Main outcomes and results: There were no significant differences between the active and control conditions on the primary outcome measure of memory functioning. However, significant improvements in use of compensatory strategies as well as family reports of improved memory and mood were observed following completion of all sessions. Individuals with less use of compensatory strategies at baseline were significantly less likely to complete the study.Conclusions: These results suggest that the Internet may be an effective delivering mechanism for compensatory cognitive rehabilitation, particularly among individuals who are already utilizing some basic compensatory strategies.

<p>The article presents the results of a study aimed at investigating the influence of two forms of virtual group pressure (depersonalized and personalized) on the manifestation of moral conformity. The experimental material consisted of two types of moral scenarios, where participants were asked to assess the acceptability of certain behaviors. Depersonalized pressure was implemented by informing participants, filling out an online form, about the percentage of people responding in a certain way to the presented moral scenarios. As for the personalized form of pressure, a situation simulating interactions among individuals in instant messaging systems (messengers) was utilized. The study involved 112 participants, with 20 of them forming the pilot study sample and 92 — the main experimental sample. The results indicate that social pressure in the virtual environment leads to the emergence of a conforming response, with personalized pressure in real-time having a stronger influence than passive exposure to depersonalized data. The obtained results are explained within the framework of the biological theory of social pressure, which views conforming behavior as a strategy to optimize metabolic costs. The manifestation of a conforming response for both types of moral scenarios and the absence of gender differences in its expression suggest the potential universality of this strategy.</p>

‘Healthcare infrastructures’ is often associated with large, complex and costly technical solutions made available by institutions. The widespread use of smart devices made possible the development of information exchange building on general purpose communication technologies. Through the analysis of an expert opinion service for breast cancer via WhatsApp, we illustrate the process of setting up the service, the challenges and the ramifications of health information exchange taking place through non-institutional channels. We introduce the concept of ‘grassroot infrastructures’ to indicate socio-technical systems created and managed by lower-ranked organizational actors, invisible to rationalized representations of work.

The spread of instant messenger systems provides an excellent opportunity and a helpful tool to healthcare professionals. WhatsApp instant messenger use is widely prevalent among health professionals, cancer patients, caregivers and the general population. It is a quick and easy communication tool that may also be used on personal computers and business purposes. WhatsApp instant messenger and other similar tools may be a very useful complement for e-medicine. Instant messaging systems may be helpful, especially in rural areas, in medium- or low-income countries, or to avoid unnecessary travels, improve knowledge and awareness of cancer, monitor home care and support the delivery of home care. The unregulated use of WhatsApp instant messenger requires sound and shared guidelines to assure impeccable professional service. Although a significant number of papers have investigated the roles of social networks in connecting patients to health professionals, there is still a lack of information and scientific data about their uses, benefits and limitations in connecting health providers only for professional communication. The role of instant messenger systems in cancer practice and research needs to be clarified. In this paper, we report a focus on available data, pros and contras of the unregulated use of WhatsApp instant messaging, in the context of e-medicine, as an interprofessional and doctor/patient communication tool in oncology.

Peer feedback has become a crucial element in the field of English as a second/foreign language (ESL/EFL) writing. There has been a notable scholarly interest in the integration of peer feedback in English writing instruction. Among Chinese undergraduate students, there is a growing tendency to use instant messaging systems, such as WeChat, for peer feedback. WeChat distinguishes itself from other platforms by its extensive usage in China, particularly owing to its user-friendly features. However, there is a lack of systematic research in the current literature to explore the effectiveness of using WeChat for peer feedback in English writing. In particular, there is a lack of research on five aspects of students’ English writing performance when using WeChat as a platform for peer feedback, such as content and idea, coherence and cohesion, grammar and form, word choice and vocabulary, and organization and structure. This article aims to provide an overview of the investigation of the effectiveness of using WeChat as an instant messaging platform through a literature review. The authors adhered to predetermined criteria for what literature were included and excluded. Ultimately, the authors reviewed a collection of 30 research articles from the year 2011 to 2023 that are directly related to the topic at hand. This review encompasses an evaluation of the research designs, findings, discussions, and gaps in research identified in these articles. This review offers a comprehensive comprehension of the present status of research in this field. Moreover, it emphasizes the need for additional academic investigation, specifically targeting the task of filling the recognized gaps in knowledge. Furthermore, the conclusion highlights the necessity of further studies, which needs to explore the long-term effects of incorporating WeChat and peer feedback on enhancing students’ writing performance. This encompasses various aspects, such as content and idea, coherence and cohesion, word choice and vocabulary, organization and structure, as well as grammar and form.

Instant Messaging (IM) services over the last few years have evolved from a casual communication tool to a formal business communication tool. Security requirements change drastically when instant messaging systems are employed in the corporate world as sensitive data needs to be transmitted. Many security enhancements have been proposed for instant messaging from the perspective of peer-to-peer talk. In this paper, we study the extension of secure instant messaging for group settings. We also propose a scheme, IBECRT, which uses ID-based encryption and the Chinese Remainder Theorem. The scheme does not require a central trusted entity for key distribution and achieves uniform work-load distribution. Additionally, the protocol has the following properties: hiding the users’ identity in a conference, authentication of senders, and integrity protection of the messages exchanged.

For better or worse, the web browser has become a widely used target platform for software applications. Desktop-style applications such as word processors, spreadsheets, calendars, games and instant messaging systems that were earlier written for specific operating systems, CPU architectures or devices are now written for the World Wide Web, to be used from a web browser. In this paper we summarize our experiences in using the web browser as a target platform for real applications. As a concrete example, we use the Sun? Labs Lively Kernel, a system that implements an exceptionally interactive web programming environment running in a web browser without any plug-in components. Based on this work, we analyze the limitations, challenges and opportunities related to the web browser as an application platform.
