Peer evaluation methods are demanded so that tutors become able to distribute assignments in a way that the work to be assigned to each student will excite his/her interest in order to make a serious rating but also give fruitful feedback comments to their peers while through this process they will acquire themselves new knowledge. In this paper, we present the design and the implementation decisions of a web-based peer-evaluation system to support the instructors of a laboratory course on AI programming to distribute the submitted students' assignments in a way tailored to their pedagogical goals. The core of the web-based system is an expert system which decides on the materialization of the time-consuming distribution procedure while granting maneuverability to the instructors to tailor the procedure to their needs.","PeriodicalId":305252,"journal":{"name":"Proceedings of the 19th Panhellenic Conference on Informatics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126924098","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}

The aim of the privacy policies is to provide direction and support for data privacy in accordance with user requirements and relevant laws and regulations; unfortunately, most of the times, OSN users seem not to fully comprehend the policies, and to face difficulties in applying privacy rules. As a result, unintentional exposure of users' data to unknown audiences is a usual phenomenon, as the users struggle to balance the sharing and the protection of their Personal Identifiable Information (PII). In this paper, we first map the privacy policies of Facebook, Google Plus, Twitter and LinkedIn onto the phases of the PII lifecycle, then we highlight the omissions found and subsequently we propose a new model privacy policy that is based on the PII lifecycle and aims to make the users understand and track all the PII phases during their engagement in OSNs.","PeriodicalId":305252,"journal":{"name":"Proceedings of the 19th Panhellenic Conference on Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128498086","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}

Furthermore, critical hints that potential drive the evolution of the blended learning model as a multi training framework for state of the art technologies with considerable education impact, are briefly discussed.","PeriodicalId":305252,"journal":{"name":"Proceedings of the 19th Panhellenic Conference on Informatics","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115183674","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}
