Microtask crowdsourcing for music score Transcriptions: an experiment with error detection

Human annotation is still an essential part of modern transcription workflows for digitizing music scores, either as a standalone approach where a single expert annotator transcribes a complete score, or for supporting an automated Optical Music …

Comparison of different driving style analysis approaches based on trip segmentation over GPS information

Over one billion cars interact with each other on the road every day. Each driver has his own driving style, which could impact safety, fuel economy and road congestion. Knowledge about the driving style of the driver could be used to encourage …

Better Call the Crowd: Using Crowdsourcing to Shape the Notation of Domain-Specific Languages

Crowdsourcing has emerged as a novel paradigm where humans are employed to perform computational tasks. In the context of Domain-Specific Modeling Language (DSML) development, where the involvement of end-users is crucial to assure that the resulting …

RSPLab, RDF Stream Processing Benchmarking made easy

In Stream Reasoning (SR), empirical research on RDF Stream Processing (RSP) is attracting a growing attention. The SR community proposed methodologies and benchmarks to investigate the RSP solution space and improve existing approaches. In this …

A Big Data Analysis Framework for Model-Based Web User Behavior Analytics

While basic Web analytics tools are widespread and provide statistics about website navigation, no approaches exist for merging such statistics with information about the Web application structure, content and semantics. Current analytics tools only …

Extending the interaction flow modeling language (IFML) for model driven development of mobile applications front end

Front-end design of mobile applications is a complex and multidisciplinary task, where many perspectives intersect and the user experience must be perfectly tailored to the application objectives. However, development of mobile user interactions is …

Pattern-based specification of crowdsourcing applications

In many crowd-based applications, the interaction with performers is decomposed in several tasks that, collectively, produce the desired results. Tasks interactions give rise to arbitrarily complex workflows. In this paper we propose methods and …

Reactive Crowdsourcing

An essential aspect for building effective crowdsourcing com- putations is the ability of 'controlling the crowd', i.e. of dynamically adapting the behaviour of the crowdsourcing systems as response to the quantity and quality of completed tasks or …
