Systematic Mapping of Open Data Studies: Classification and Trends From a Technological Perspective

Abstract

The objective of this paper is to classify and analyse all research on open data performed in the scientific community from a technological viewpoint, providing a detailed exploration based on six key facets: publication venue, impact, subject, domain, life-cycle phases and type of research. This paper therefore provides a consolidated overview of the open data arena that allows readers to identify well-established topics, trends, and open research issues. Additionally, we provide an extensive qualitative discussion of the most interesting findings to pave the way for future research. Our first identification phase resulted in 893 relevant peer-reviewed articles, published between 2006 and 2019 in a wide variety of venues. Analysis of the results shows that open data research grew slowly from 2006 but increased significantly as from 2009. In 2019, research interest in open data from a technological perspective overall decreased. This fact could indicate that research is beginning to stabilise, i.e., the open data research hype is over, and the research field is reaching maturity. Main findings are (i) increasing effort in researching on Semantic Web technologies as a mechanism to publish and reuse linked open data, (ii) software systems are proposed to solve open data technical problems; and (iii) considering technological aspects of legislation and standardization is needed to widely introduce open data in society. Finally, we provide complementary insights regarding open data innovation projects, with special emphasis on publication (e.g., open data portals) and consumption (e.g., open data as business enabler) of open data.

Smarter Open Government Data for Society 5.0: Are Your Open Data Smart Enough?

“…While IoT and Smart city are becoming more active topics from year to year, the study in question does not strongly support this fact, as the most "fruitful" year for both topics, sensor-and real-time data, was 2018, with a slight decline in their popularity in the scientific literature in the following years. However, despite the fact that the number of studies on both topics was the highest in 2018, the trend is positive and will increase in the coming years in all digital libraries inspected, with the exception of ACM Digital Library (also in line with [31]). It can therefore be concluded that, although many studies emphasize the significance of the concepts under consideration, real-time data and sensor-generated data, in particular, are more complementary materials that are rarely central to the study, despite their high importance and economic and innovative potential.…”

“…Another expressive solution demonstrating the potential of open (government) data moving toward Smart Society is the WeLive project [ 31 ], whose objective is to transform the current e-government approach by facilitating a more open model of design, production and delivery of public services, based on the collaboration among different stakeholders, i.e., citizens, public administrations, private companies and research institutes. The use of such concepts as open innovation, open data and open services paradigms allowed the authors to develop the framework, enabling the co-creation of urban apps.…”

The WeLive platform offers a set of tools that enables cooperation among different stakeholders, transforming needs into ideas, selecting the best ideas and creating the building blocks necessary for the desired solutions, composing them into mass market apps that are available through the WeLive Marketplace.…”

Open Data-driven Usability Improvements of Static Code Analysis and its Challenges

“…The questions about open data is relevant for several domains and topics as seen in a recent systematic mapping study [8]. Even if the most common domain is "infomediaries", i.e.…”

“…In OSS development, there are accepted ways of sharing results in communities [9], and the term "open data" [8] denotes a trend in which for example public organizations provide data to other organizations. In this paper, we analyse to what extent the view on OSS and open data carry across to data for open data-driven tuning of software development tools.…”
