The perception of emotional and affective state in present and past group's activities is a relevant issue since emotional awareness influence the outcome of cooperative work. While there is a growing interest in providing computational support for recognition and representation of emotions, few research efforts explore the potential of Brain Controlled Interfaces (BCI) to collect and present emotional awareness in synchronous collaborative systems. In this paper, we present an initial step in exploring how a low-cost off-the-shelf electroencephalograph (EEG) system can be used to provide emotional awareness information in synchronous collaborative editing systems.","PeriodicalId":257965,"journal":{"name":"2012 Brazilian Symposium on Collaborative Systems","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132323034","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}

Newcomers face difficulties and obstacles when starting their contributions, resulting in a large withdrawal and consequent low retention rate. This paper presents an analysis of newcomers withdrawal, checking if the dropout is influenced by lack of answer, answers politeness and helpfulness, and the answer author. We have collected five years data from the developers mail list communication and task manager (Jira) discussions of Hadoop Common project. We observed the users' communication, identifying newcomers and classifying questions and answers content. For the study conducted, less than 20% of newcomers became long term contributors. There are evidences that the withdrawal is influenced by the respondents and by the type of response received. However, the lack of answer was not evidenced as a factor that influences newcomers withdrawal in the project.","PeriodicalId":257965,"journal":{"name":"2012 Brazilian Symposium on Collaborative Systems","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126724569","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}

A new approach for that is the use of NeuroLinguistic theory to determine what is the Preferred Representational cognitive System (PRS) of collaborators. Internal mental processes such as problem solving, memory, and language consist of visual, auditory and kinesthetic representations. An important question on this matter is: Classify the representation most used (PRS) on moment of the text interactions can increase empathy? This position paper presents a psychometrically-based neurolinguistic proposal to enhance the empathy in the Computer-Mediated Communication.","PeriodicalId":257965,"journal":{"name":"2012 Brazilian Symposium on Collaborative Systems","volume":"294 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130647135","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}

Thus, health professionals and students can exchange views and experiences by discussing medical cases. The purpose of this paper is to present Sanar, a collaborative web environment where professionals and students can create discussions about new cases or contribute to existing cases' discussions. This solution promotes the growth potential of the group through individual contributions, with the aim of building the medical case. It also allows the study of the different mechanisms of interaction in a global context, through the potential of Web 2.0. The Sanar prototype was developed and evaluated by doctors living in Brazil and Spain, who indicated the usefulness of the approach.","PeriodicalId":257965,"journal":{"name":"2012 Brazilian Symposium on Collaborative Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131852775","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}

From the classifier developed for this study, it was found 99.4% overall accuracy in a 10-fold cross validation test.

Our approach uses context information in order to personalize the access experience according to users preferences.
