In this paper we argue that understanding the provenance of social media datasets and their analysis is critical to addressing chal- lenges faced by the social science research community in terms of the reliability and reproducibility of research utilising such data. Based on analysis of existing projects that use social media data, we present a number of research questions for the provenance community, which if addressed would help increase the transparency of the research process, aid reproducibility, and facilitate data reuse in the social sciences.

Many online platforms employ networks of human workers to perform computational tasks that can be difficult for a machine (e.g. reporting travel disruption). Such systems have to make a range of decisions, for example, selection of suitable workers for a task. In this paper we present an approach that utilises Semantic Web technologies and provenance to support such decision-making processes.

We argue that existing systems to support social computation suffer from a lack of transparency and that this can be addressed by integrating provenance capture mechanisms into such systems. We discuss how Semantic Web technologies can be used to facilitate this, and how the provenance record could be used to support various forms of decision-making about tasks such as workforce selection.
GetThere is a real-timepassengerinformationsystem(RTPI) for rural areas that uses a citizen sensing approach to acquire information from public transport users. This paper describes the use of ontologies in GetThere to represent and integrate citizen sensors with data required to provide RTPI (e.g. timetable and route descriptions). The service architecture used to manage semantic sensor data is also described.

Social machines that outsource tasks to the crowd often have to address issues associated with the quality of contributions. In this paper we discuss a solution based on the maintenance and use of a provenance record.

Human computation systems that outsource tasks to the crowd often have to address issues associated with the quality of contributions. We are exploring the potential role of provenance to facilitate processes such as quality assessment within such systems. In this demo we present an application for managing traffic disruption reports generated by the crowd, and outline the technologies used to integrate provenance, linked data, and streams.

Real time passenger information (RTPI) is commonly available in urban areas for immediately before and during journeys; however, non-urban areas (e.g. suburban, rural, and remote areas) often have little or no access to it. One of the main challenges in providing RTPI in rural areas is the lack of infrastructure for obtaining real time vehicle location, and for providing information to passengers. In the Informed Rural Passenger Project, we attempt to address this problem through the use of passengers' smartphones. We have developed GetThere, a smartphone app that crowdsources travel information, including vehicle location, from the passengers. This information is then integrated using linked data principles with open data from various sources, and used by various web services to provide RTPI to travellers in rural areas. Initial evaluation of the GetThere system has been performed on urban, suburban, and rural bus routes in the North East of Scotland.
The usefulness of intelligent applications/services reasoning with linked data is dependent on the availability and correctness of this data. The crowd potentially has an important role to play in performing the non-trivial tasks of creating, validating, and maintaining the online linked data sets used by applications and services. Additional information captured within a provenance record can be used in these tasks and others, such as evaluating the performance of the crowd and its members. In this paper we describe two roles for the crowd in the web of linked data (creation and maintenance), and argue that incorporating provenance into these tasks is beneficial especially in scenarios when the population of available workers is small. We also identify several challenges for the use of provenance in this context and define a set of requirements for a provenance model to address these challenges.
