Crowdsourcing is an effective tool for scalable data annotation in both research and enterprise contexts. Due to crowdsourcing’s open participation model, quality assurance is critical to the success of any project. Present methods rely on EM-style post-processing or manual annotation of large gold standard sets. In this paper we present an automated quality assurance process that is inexpensiv...

We estimate sentiment categories proportions for retrieval within large retrieval sets. In general, estimates are produced by counting the classification outcomes and then by adjusting such category sizes taking into account misclassification error matrix. However, both the accuracy of the classifier and the precision of the retrieval produce a large number of errors that makes difficult the ap...

Ubiquitylation is an essential posttranslational modification that can regulate the stability, activity, and localization of thousands of proteins. The reversible attachment of ubiquitin as well as interpretation of the ubiquitin signal depends on dynamic protein networks that are challenging to analyze. In this perspective, we discuss tools of the trade that have recently been developed to dis...

We present a system which aids content management during the preand post-processing aspects of digital film production. Editors can synchronize their footage with their imported scripts to help in the organization of the video "bin". In addition to this, we provide a zoomable interface to facilitate the process and help organize pre-production media such as images, and video

The fair evaluation of leaking devices generally requires to come with the best possible distinguishers to extract and exploit sidechannel information. While the need of a sound model for the leakages is a well known issue, the risks of additional errors in the post-processing of the attack results (with key enumeration / key rank estimation) are less investigated. Namely, optimal post-processi...

This article assesses the achievement of land reform in South Africa with respect to the number of beneficiaries relative to rural employment and the demand for land and increases in livelihoods and agricultural output. Even though there are islands of success, for the past twenty years the Land Reform Programme has not satisfied these criteria. Implementation has been poor and farm workers’ an...

In the validation phase of a commercial CFD code, the importance of scientific data management for visualization and knowledge preservation surfaced. The proposed Scientific Data Bag (SDB) solution offers a lightweight method to record metadata and relationship between related datasets in a file structure preserving access to data files in their native format. An interface layer provides servic...

Local anaesthetic drugs are used widely for the provision of anaesthesia and analgesia both intraand post-operatively. Understanding the pharmacology of these agents as a group, as well as the differences between specific drugs, enables the anaesthetist to use them safely to maximum effect. This tutorial focuses on the basic structure and function of local anaesthetics. Learning will be improve...
