Creating descriptive labels for pictures is an important task with applications in image retrieval, Web accessibility and computer vision. Automatic creation of such labels is difficult, especially for pictures of artworks. “Games With A Purpose” strive to create image descriptions by harnessing the intelligence of human players.

We present pest, a novel approach to approximate querying of structured wiki data that exploits the structure of that data to propagate term weights between related wiki pages and tags. Based on the pest matrix, eigenvectors representing the distribution of a term after propagation are computed. The result is an index which takes the document structure into(More)
Traditional linguistic field research employs the cost-and time-consuming and possibly biased approach of gathering data by sending out researchers and filling in questionnaires. We improve linguistic field research using crowdsourcing techniques to remedy these issues and open research to a wider audience. On the online platform MetropolItalia, going(More)

Linguistic field research depends on collecting phrases and sentences as well as their geographical and social characteristics. Collecting such data is usually done by sending researchers in the field to ask questions and fill forms. This traditional field research is time-consuming, costly, and not free of biases. This demonstration paper presents(More)
A concept map is a visual representation of concepts as nodes and of relationships between concepts as edges as a diagram consisting of nodes linked with each other. Concept maps support the learning process inasmuch that they make learners aware of their own progresses. We propose a game-like e-learning tool named Termina to be used for assessing learners'(More)
