Multilingual users of social media and social networking sites are invisible -even unconscious- translators. Their language skills and multicultural background could help diminish the segmentation of information spheres online by connecting different language communities. Focusing on the microblogging site Twitter, this study aims at defining and classifying language bridges by looking at the languages and structure of the social networks of multilingual individuals. The social network analysis unveils four types of structures, one of which is defined as a language bridge. The next step of this work in progress aims at providing quantitative measures of this phenomenon, which has not been yet properly described or understood.
The goal of this study is to compare social tagging patterns in two languages in image collections of art, while seeking exploitable strengths for the application of multilingual social tagging in digital libraries an...

We propose an image search system for flowers on a mobile phone. Mobile phones have more limited resources than desktop computers in terms of CPU, RAM and data storage. The database that we created has 45 classes. We used 182 training images and 246 test images. We used an HSV histogram as a color feature. The accuracy rate using only color features was 44.86% with radius C=20. We use SURF as a shape feature. The accuracy rate using only shape-based featurewas 47.31% with SURF vectors S=25. We combine both color and shape features to achieved accuracy 61.61%.
Efficient analysis of event sequences and the ability to answer time-related, clinically important questions can accelerate clinical research in several areas such as causality assessments, decision support systems, a...

We describe the first iteration of an Alternate Reality Game (ARG) designed to lead players into a newly enfranchised relationship with history and engage them in scientific thinking and information literacy practices. We found that the points at which the game's mythology blurred the lines between fact and fiction prompted middle school students to move beyond rote memorization of content. Instead, they began to question, analyze, and make hypotheses about the data presented. However, striking a meaningful balance between "true" history and imagined events poses new design challenges. We present a formative typology of counterfactual design patterns that can help designers, educators, and players locate interesting fault lines in reality that facilitate the expansion of ARG mythologies.
