This paper describes the HASY dataset of handwritten symbols. HASY is a publicly available, free of charge dataset of single symbols similar to MNIST. It contains 168 233 instances of 369 classes. HASY contains two challenges: A classification challenge with 10 pre-defined folds for 10-fold cross-validation and a verification challenge.

We introduce and make publicly available an entity linking dataset from Reddit that contains 17,316 linked entities, each annotated by three human annotators then grouped into Gold, Silver, Bronze to indicate inter-annotator agreement. analyze the different errors disagreements made suggest types of corrections raw data. Finally, we tested existing models are trained tuned on text non-social me...

In recent years, with the rapid development of unmanned aerial vehicles (UAV) technology and swarm intelligence technology, hundreds small-scale low-cost UAV constitute swarms carry out complex combat tasks in form ad hoc networks, which brings great threats challenges to low-altitude airspace defense. Security requirements for defense, using visual detection detect track incoming swarms, is pr...

Ranked search of datasets has emerged as a need as shared scientific archives grow in size and variety. Our own investigations have shown that IRstyle, feature-based relevance scoring can be an effective tool for data discovery in scientific archives. However, maintaining interactive response times as archives scale will be a challenge. We report here on our exploration of performance technique...

The "Ajeijadinho 3D" project is an initiative supported by the University of São Paulo (Museum of Science and Dean of Culture and Extension), which involves the 3D digitization of art works of Brazilian sculptor Antonio Francisco Lisboa, better known as Aleijadinho. The project made use of advanced acquisition and processing of 3D meshes for preservation and dissemination of the cultural herita...

A photographic dataset is collected for testing image processing algorithms.
