Members of The Science Circle, an international alliance of science educators and enthusiasts, were surveyed about their experiences and attitudes towards communicating science in Second Life. 36 survey respondents expressed overwhelmingly positive experience communicating, teaching, and learning science concepts there. They also largely agreed that virtual worlds include features that enhance learning in ways that are difficult to reproduce in physical settings.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123247337","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 project our principal task is to build data warehouse schema from handicraft women social network. For that, we follow a semi-supervised clustering-based methodology. In this paper, we propose the adaptation of a semi-supervised hierarchical clustering based on ranking mixed features for the FAOF ontology. This later serves as perfect input data for clustering. The main contribution is to use ontology-based similarity measures that combine numerical and nominal variables along different dimensions (instances, attributes, and relation-ships) and to provide a performable clustering algorithm based on ranking features. The evaluation of the used clustering methods in the context of the project emphasizes it effectiveness to generate valid clusters which can be successfully used for extending the data warehouse schema.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"448 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123231130","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}

These systems gained high popularity among users due to their relatively low cost and continuous expansion towards better functionalities and performance. We believe that the pervasive utilization of these systems and ease of use help us build mobile applications that are of big aid for people with disabilities. In this paper, we present My vWallet, an easy to use interactive smartphone application dedicated to assist people suffering from dyscalculia, mathematical computation difficulties and mild or moderate mental deficiency to easily overcome situations where money managing and exchange is required. Our application provides an interactive and easy to use graphical user interface, which provides an efficient and simple way for handling monetary exchange. To the best of our knowledge, this is the first attempt to develop a mobile software that targets this issue.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128169804","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}

SaaS is based on Service Oriented Architectures and Web Service technology which are popular paradigm to design new generation of applications. These functionalities are published on the Internet, but exploiting rigorously a large data stream in order to use Web Services is a complicated and laborious task which may involve error prone. In this paper we investigate the problem of SaaS Web Service Composition. We present a new technique that translates the problem of minimum SaaS Web Services composition into MaxSAT problem.

The majority of printed dictionaries organize ArSL signs (represented in drawings or pictures) based on their nearest Arabic translation; so unless one already knows the meaning of Arabic sign, dictionary look-up is not a simple proposition. In order to build Arabic signs recognition system, standard database of Arabic signs is required to validate the results, however, this database is absent. In this paper, we introduce the ArSL database, a large and expanding public dataset containing video sequences of thousands of distinct ArSL signs. The database is collected using digital camera, Microsoft Kinect 2 sensor and Leap motion tracking sensor. This dataset is created as part of a project to develop an Arabic sign language translator. This database contents and variations qualifies it to be a benchmark database for ArSL in both research and commercial purposes.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122293473","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}

It helps them understanding what they read, express their thoughts and communicate with others. Despite this importance, vocabulary acquisition remains a hard task which requires a higher motivation level. On the other hand, learning games are considered as one of the effective ways for increasing learner's desire to learn. This paper presents an accessible version of the popular crosswords game for deaf learners. It allows learning Arabic vocabulary in a fun and interactive way. The game was used by 38 learners. The obtained results showed that the game enhances the learners' level of knowledge regarding Arabic vocabulary. Besides, it showed that the learners are very satisfied with learning vocabulary using the game.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132168331","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}

Our module is a component of the framework PMAF (Personalized Mobile Assessment Framework) that aims to provide personalized mobile assessment resources. The use of semantic web technologies is explained with the feature of ensuring data interoperability and reuse of mobile feedback resources. In addition, an investigation for the enhancement of the defined feedback in IMS/QTI specification is presented. In our approach, a personalized mobile feedback module based on web services uses the learner's information stored in his/her e-portfolio to continuously suggest the most appropriate and personalized feedback in a particular field of knowledge to ensure the achievement of learning goals.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134434682","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}
