This position paper points out six citizen-related challenges: engagement citizens, improvement citizens’ data literacy, pairing...

Participatory design (PD) in HCI has been successfully applied to vulnerable groups, but further research is still needed on forced migrants. We report a month-long case study with group of about 25 young migrants (YFMs), where we and adapted strategies from PD participatory (PR). gained insights into the benefits drawbacks combining PR concepts this particular scenario. The PD+PR approach supported intercultural collaborations between YFMs members host community. It also enabled...

Ontologies are key to information retrieval, semantic integration of datasets, and similarity analyses. Evaluating ontologies (especially defining what constitutes a "good" or "better" ontology) is therefore central importance for the Semantic Web community. Various criteria have been introduced in literature evaluate ontologies, this article classifies them according their relevance design implementation phase ontology development. In addition, compiles strategies evaluation based on...

'Safe spaces' have been at the core of participatory design (PD) in HCI. However, their characteristics, potential impact and what enables them are not yet fully understood. The present article presents a series insights derived from six-week long study with 19 young forced migrants (YFMs). We investigated factors which contributed to enable creation 'safe while developing digital services them. based our case on four main components such spaces: (i) ethics, (ii) reflective processes, (iii)...

Open data initiatives are playing an important role in current city governments. Despite more being made open, few studies have looked into barriers to open geographic reuse from a consumer’s perspective. This article suggests taxonomy of these for Colombia and Spain, based on literature review, online questionnaire, workshops conducted four cities two countries. The highlights that issues such as outdated data, low integration producers, published difficult access, misinterpretation misuse...

The linked data Web provides a simple and flexible way of accessing information resources in self-descriptive format. This offers realistic chance perforating existing silos. However, order to do so, space, time other semantic concepts need function as dimensions for effective ly exploring, querying filtering contents. While triple stores, SPARQL endpoints, RDF were designed machine access, large burdens are still placed on user simultaneously explore query the contents given endpoint...

The availability of open data and tools to create visualizations on top these datasets have led an ever-growing amount geovisualizations the Web. There is thus increasing need for techniques make FAIR - Findable, Accessible, Interoperable, Reusable. This article explores what it would mean a geovisualization be FAIR, presents relevant approaches lists research questions road towards geovisualizations. discussion done using three complementary perspectives: computer, which stores digitally;...

Public displays can be used to support public participation in urban settings. This article provides a survey of the use for an context, covering articles on this topic published between 2012 and 2016. 36 papers were selected analysed along eight dimensions: type political scientific contribution, standalone vs with device, single multi-purpose displays, shape lab field study, deployment semi-public space, level addressed. Our analysis revealed number trends regarding Inspecting these also...

A very common curb of epidemiological studies for understanding the impact air pollution on health is quality exposure data available. Many rely empirical modelling techniques, such as land use regression (LUR), to evaluate ambient exposure. Previous have located monitoring stations in an ad hoc fashion, favouring their placement traffic “hot spots”, or areas deemed subjectively be interest and population. However, ad-hoc may lead uninformed decisions long-term analysis. This paper...

Air quality has had a significant impact on public health, the environment and eventually economy of countries for decades. Effectively mitigating air pollution in urban areas necessitates accurate exposure information. Recent advancements sensor technology increasing popularity volunteered geographic information (VGI) open up new possibilities assessment cities. However, citizens their sensors are put deemed to be subjectively interest (e.g., where live, school kids or working spaces), this...

n recent years, large numbers of forced migrants have arrived in urban areas all around the world. Access to relevant information and suitable technology can help migrants, mainly refugees asylum seekers, cope with several challenges they face this process. We conducted a qualitative study ten six social workers staff member collective lodging for young Munster, Germany. The goal was identify needs specific context, find criteria assessing digital support services suggest general aspects...

Disclosing the current location of a person can seriously affect their privacy, but many apps request information to provide location-based services. Simultaneously, these only crude controls for privacy settings (sharing all or nothing). There is an ongoing discussion about rights users regarding (e.g. in context General Data Protection Regulation – GDPR). GDPR requires data collectors notify collection and them with opt-out options. To address requirements, we propose set user interface...

Road traffic and its impacts affect various aspects of wellbeing with safety, congestion pollution being significant concern in cities. Although there have been a large number works done the field data collection, are several barriers which restrict collection at higher resolution Installation maintenance costs can act as disincentive to use existing methods (e.g., loop detectors, video analysis) scale hence limit their deployment only few roads city. This paper presents an approach for...

Open government datasets (OGD) have been flooding the Web in recent years. Geovisualisations are natural way of making sense them, and gradually coming out. However, one key problem is lack flexibility these visualizations, which severely limits their re-use new scenarios. This article therefore proposes to increase intelligence existing geovisualisations by incorporating five features, make better use OGD: (i) automatic geographic data type recognition, (ii) generation geovisualisation...

Citizen participation is an important part of urban planning but few people participate, and most frequently they can do so only passively. This result in excluding many to designs not reflecting people's wishes. In this paper, we explore the use interactive, immersive public displays as facilitators for deeper planning. We propose a novel approach that combines panoramic videos locations with overlays depicting planned buildings. evaluated it lab-based user study (N = 21), where...

Choropleth maps and graduated symbol are often used to visualize quantitative geographic data. However, as the number of classes grows, distinguishing between adjacent increasingly becomes challenging. To mitigate this issue, work introduces two new visualization types: choriented (maps that use colour orientation variables encode information) mobile (an optimization for devices). The were evaluated in a graphical perception study featuring comparison SDG (Sustainable Development Goal) data...
