As social media and online activity continue to pervade all age groups, it serves as a crucial platform for sharing personal experiences and opinions as well as information about attitudes and preferences for certain interests or purchases. This generates a wealth of behavioral data, which, while invaluable to businesses, researchers, policymakers, and the cybersecurity sector, presents significant challenges due to its unstructured nature. Existing tools for analyzing this data often lack the capability to effectively retrieve and process it comprehensively. This paper addresses the need for an advanced analytical tool that ethically and legally collects and analyzes social media data and online activity logs, constructing detailed and structured user profiles. It reviews current solutions, highlights their limitations, and introduces a new approach, the Advanced Social Analyzer (ASAN), that bridges these gaps. The proposed solutions technical aspects, implementation, and evaluation are discussed, with results compared to existing methodologies. The paper concludes by suggesting future research directions to further enhance the utility and effectiveness of social media data analysis. 展开更多

Wuthering Heights was an extraordinary novel in the nineteenth century,for it is very different from other contemporary novels which are reconciled with the public opinion by presenting Victorian values and tastes.It depicts a story of strong love and extreme hatred.This paper used the game theory to analyse the behaviors of Heathcliff in the Wuthering Heights.Some basic strategies and game models were used to illustrate the choices of the characters.This paper can be divided into four parts.The introduction is to introduce the novel,the description of the research approach and the definition of basic theories.It emphasizes on the introduction of basic strategies and some game models which would be used for the later analysis.The second part is to discuss the formation of Heathcliff's dual personality and analyses its causes.Heathcliff was very cruel in his revenge,but he also has a tender side in love,that is the manifestation of his dual personality.The formation of his dual personality dates back to his childhood suffering,the abnormal family environment,the pressure from long labor and finally his only love—Catherine's betrayal.The third part focuses on discussing how his dual personality affects Heathcliff's choices in the game plays with others.His tender personality affected Heathcliff's choice when facing Catherine's betrayal.He could not choose a grim strategy to totally break up with her,but choose a Tit for Tat and to combine with her after a revenge.His cruel personality made him harm other people indifferently which hide the foreshadowing for his death.The conclusion summarizes the arguments of this paper.This paper analyses from the formation of Heathcliff's dual personality,and then analyzes how his dual personality affected his choices in the game plays with others. 展开更多

Purpose:The goal of our research is to suggest specific Web metrics that are useful for evaluating and improving user navigation experience on informational websites.Design/methodology/approach:We revised metrics in a Web forensic framework proposed in the literature and defined the metrics of footprint,track and movement.Data were obtained from user clickstreams provided by a real estate site’s administrators.There were two phases of data analysis with the first phase on navigation behavior based on user footprints and tracks,and the second phase on navigational transition patterns based on user movements.Findings:Preliminary results suggest that the apartment pages were heavily-trafficked while the agent pages and related information pages were underused to a great extent.Navigation within the same category of pages was prevalent,especially when users navigated among the regional apartment listings.However,navigation of these pages was found to be inefficient.Research limitations:The suggestions for navigation design optimization provided in the paper are specific to this website,and their applicability to other online environments needs to be verified.Preference predications or personal recommendations are not made during the current stage of research.Practical implications:Our clickstream data analysis results offer a base for future research.Meanwhile,website administrators and managers can make better use of the readily available clickstream data to evaluate the effectiveness and efficiency of their site navigation design.Originality/value:Our empirical study is valuable to those seeking analysis metrics for evaluating and improving user navigation experience on informational websites based on clickstream data.Our attempts to analyze the log file in terms of footprint,track and movement will enrich the utilization of such trace data to engender a deeper understanding of users’within-site navigation behavior. 展开更多

Human activities on street spaces are affected by both physical and non-physical settings on streets.These two aspects are primarily impacted by land use which results in the uneven distribution of different activities on streets.This research investigates land use patterns and their characteristics in association to user’s behaviors.By using mixed qualitative and quantitative research methods,e.g.,place-centered behavioral map,observation,visual encounter surveys,machine learning,the relationship between user’s behavior and land use characteristics along the street is unveiled.All user behaviors along both types of streets were classified into six main categories,with 26 subcategories.The observation results show that the residential use of land along the street was transformed into the commercial use for various types of shophouses based on the resident’s ideas.There is a great correlation between land use and user’s activities.These findings give support to authorities to manage urban streets and develop a sustainable policy for improving street spaces.Further,this research contributes useful information to urban designers and planners in creating a successful street space that is appropriate for the Vietnam Community. 展开更多

Pronunciation is the basic of learning a language and an important breakthrough point to promote the whole level of language.As a result,pronunciation attracted more and more attention in English teaching.However,it is still a weakness in English teaching because of the multifarious and complicated factors.A large numbers of research papers indicate that teacher is the leader and organizer of teaching activities,he or she dominants the whole process of pronunciation teaching.For example,they make decisions,design and reform the content of teaching in the classroom.What's more,teacher's beliefs can influence their teaching behaviors more than their professional knowledge,namely,teacher's phonetic teaching beliefs influence their phonetic teaching behaviors deeply.This study aims at finding out about teachers'beliefs of phonetic teaching and casting some light on the relationship between teachers' phonetic teaching beliefs and behaviors,and the causes for their inconsistency if any. 展开更多

Users can easily post a message as a short text when they experience emotions such as pleasure or sadness. Such tweet serves to acquire empathy from followers, and can possibly influence others' emotions. In this study, we analyze the influence of emotional behaviors to user relationships based on Twitter data using two dictionaries of emotional words. Emotion scores are calculated via keyword matching. Moreover, we design three experiments with different settings: calculate the average emotion score of a user with random sampling, calculate the average emotion score using all emotional tweets, and calculate the average emotion score using emotional tweets, excluding users of few emotional tweets. We evaluate the influence of emotional behaviors to user relationships through the Brunner-Munzel test. The result shows that a positive user is more active than a negative user in constructing user relationships in a specific condition. 展开更多
