Several studies attempt to detect attendance at the time of the event from social media using geo-tagging or event-based social networks. In this study, we present a novel attendance classifier based on an LSTM and show that it outperforms other machine learning algorithms on two recent data sets with a few thousand attendees. The attendance prediction is based on the content of tweets alone, without the need for network or geospatial information. The pertinent analysis of the tweets requires text pre-processing, a sequence of steps that are implicit in the classification process and generally not discussed in other studies. We conducted a sensitivity analysis of text pre-processing steps and found that some steps like stemming and the removal of a custom list of stop words did nothing to improve the result, but the removal of mentions, punctuation and numbers proved very useful in terms of the results. The best-performing combination was identical for both data sets and led to a 6% improvement of the classification performance compared to the worst-performing combination.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125004520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While this trend is penetrating the health industry, the mobile apps available are mostly fitness-related or health service provider-centric. Apps to help patients manage their conditions and health records are rare. Objective: The purpose of this study was to design a mobile app to help cancer patients manage their stressful daily routine and health records during their cancer journey. The study also investigated ways blockchain technologies can be deployed to ensure data on the app can be stored securely and that ownership of data belongs to the patient. Methods and Results: A survey and interviews were conducted, and a working prototype was developed based on the features requested by patients and carers. Conclusion: In this article, a patient-centric app for people dealing with cancer is presented. It was developed as a prototype following pilot research investigating patients’ needs and requirements during their cancer journeys. This research paper also analyses the use of blockchain technologies to empower patients to own their health data. Finally, as this is research in progress, we discuss how this study will be advanced and the future work planned.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127705355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this approach, ethnographic data collection and analysis methods are applied to the study of game NPCs. The proposed approach has been tested in a single case study, an exploration of the appearance of “independent lives” among NPCs in the computer roleplaying game Fallout 4. This case study was motivated by the suggestion that the appearance of NPC autonomy is a key contributing factor to the commonly desired qualities of realism and believability. A total of 273 hours of ethnographic fieldwork were conducted, and ethnographic analysis of the resulting data led to an emergent framework of evidence for the appearance or illusion of NPCs leading independent lives. In this paper I discuss and evaluate the applicability of real-world ethnographic methods to NPCs as virtual human subjects, as explored through the case study. The ability to apply most of the tested methods to NPCs without significant modification to textbook examples of real-world applications supports NPC Ethnography as a valid methodological approach. The generation of useful results through the preliminary Fallout 4 case study illustrates the potential utility of NPC Ethnography as a methodology for applied NPC studies in games and virtual environments.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132913301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In helping contexts, building human-agent rapport is important for a successful supportive relationship. Positive first impressions will get the relationship off to a good start and are typically based on appearance and preferences or biases. We have conducted a study with 174 young adults (aged 18-30) to determine their preferences for the look of a character in a helping role with respect to the character’s age, gender and ethnic appearance. After briefly meeting and ranking 12 animated characters, participants interacted with their top-ranked character. We measured the level of rapport established and general attitude to using virtual humans for support. About half of the participants said gender or ethnic appearance did not matter and preferred a peer-aged character that played the role of a friend. The other half preferred an older character who was female if they were female, or split if male. Significant differences based on participant gender, course studied, openness to experience personality trait and depression and anxiety levels were found for preferences but not rapport scores. Participants were mostly agreeable to using a virtual support person, though reluctant to recommend one to a friend. Our study identifies the importance of user profiling and tailoring of graphical models for certain personality types or psychological states.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123444998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is further fueled with the entrance of Internet of Things (IoT), where mobile health devices have resulted in an explosion of health data and increased accessibility via wireless communications and sensor networks. With the introduction of an Electronic Health Record (EHR) system as an important venture for the general health and wellbeing of a country's citizens, privacy issues and medical disputes are expected to rise. In addition to critical health information being documented and shared electronically, integrating data from diverse smart medical IoT devices are leading towards increasingly more complex disputes that require immense time and effort to resolve. Online dispute resolution (ODR) programs have been successfully applied to cost-effectively help disputants resolve commercial, insurance and other legal disputes, but as yet have not been applied to healthcare. This paper takes a modest step in this direction, firstly to identify the drivers of medical disputes that include patient empowerment and technology advancements and trends. Secondly, we explore dispute resolution models and identify the status and limitations of current ODR systems.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132846821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
