“…Usually, the categories with which to describe the activities of a community refer to a few major themes such as transportation, economics, government, education and public safety. Notwithstanding, noticeable variations emerge in the way OGD portals select the number and terminology of the categories with which to group their data sets [60]. Zencey [59] analysing the popularity of the topics among the data sets published by 141 US public bodies noted that ‘popular data sets varied significantly based on location’ 30 and that this variation may ‘expresses local preferences and needs’.…”

“…Our choice to focus on the US city portals, besides the fact that many of these city governments were among the first to adhere to Open Data practices [58], under the government’s impetus by President Obama, is due to the interest showed towards these portals in the literature. In fact, in recent years, following the considerable efforts made by US cities to publish Open Data and encourage citizens to use them [43,46], several scholars have investigated their characteristics [8,59,60] and analysed their performance [43,44,46]. For example, Zhu et al [43], in a study on 34 US cities, found that the city population is positively related both to the number of its portal’s data sets as well to an overall score based on a set of portal-level metrics they defined and manually tested.…”

Open Government Data: Usage trends and metadata quality

Open Government Data (OGD) have the potential to support social and economic progress. However, this potential can be frustrated if these data remain unused. Although the literature suggests that OGD data sets’ metadata quality is one of the main factors affecting their use, to the best of our knowledge, no quantitative study provided evidence of this relationship. Considering about 400,000 data sets of 28 national, municipal and international OGD portals, we have programmatically analysed their usage, their metadata quality and the relationship between the two. Our analysis has highlighted three main findings. First, regardless of their size, the software platform adopted, and their administrative and territorial coverage, most OGD data sets are underutilised. Second, OGD portals pay varying attention to the quality of their data sets’ metadata. Third, we did not find clear evidence that data sets’ usage is positively correlated to better metadata publishing practices. Finally, we have considered other factors, such as data sets’ category, and some demographic characteristics of the OGD portals, and analysed their relationship with data sets’ usage, obtaining partially affirmative answers.

“…Based on the result of the semantic interpretation of the user's question, we retrieve the title and description of the datasets. In work [21], the authors also take a similar approach, implementing a semantic analysis based on open government data, but the analysis is performed to minimize misunderstandings with the the semantics of the dataset categories used.…”

Public administration is one of the largest producers and collectors of data in several domains. Bearing in mind that one of the main pillars of public transparency is the release of social value through government data, and that this right remains a challenge for citizens, in this work we implemented a methodology that uses techniques and Answers and Information Retrieval to retrieve data sets and respond to questions from citizens on a Brazilian open government data portal. Using metrics of information retrieval evaluation, such as accuracy and recall, we obtained satisfactory results in applying the proposed methodology.

“…For instance, Gill [16] focused on how the potential benefits of open data are conceived differently by municipality representatives depending on the municipality size in Western Canada; Gill and Corbett [17] focused on testing the connection between the efficacy of open data portals and the population size of municipalities in Canada; Gill, Corbett, and Sieber [21] examined how the size of municipalities influences how open data is developing at municipalities of different sizes in Western Canada. In addition, Thorsby et al [22] looked at the impact of the population size of American cities and their level of resources on the number of datasets made available, and, Pinto et al [23] categorized the datasets of open data portals of large American cities.…”

Motivation Perspectives on Opening up Municipality Data: Does Municipality Size Matter?

2018

National governments often expect municipalities to develop toward open cities and be equally motivated to open up municipal data, yet municipalities have different characteristics influencing their motivations. This paper aims to reveal how municipality size influences municipalities’ motivation perspectives on opening up municipality data. To this end, Q-methodology is used, which is a method that is suited to objectify people’s frames of mind on a particular topic. By applying this method to 37 municipalities in the Netherlands, we elicited the motivation perspectives of three main groups of municipalities: (1) advocating municipalities, (2) careful municipalities, and (3) conservative municipalities. We found that advocating municipalities are mainly large-sized municipalities (>65,000 inhabitants) and a few small-sized municipalities (<35,000 inhabitants). Careful municipalities concern municipalities of all sizes (small, medium, and large). The conservative municipality perspective is more common among smaller-sized municipalities. Our findings do not support the statement “the smaller the municipality, the less motivated it is to open up its data”. However, the type and amount of municipality resources do influence motivations to share data or not. We provide recommendations for how open data policy makers on the national level need to support the three groups of municipalities and municipalities of different sizes in different ways to stimulate the provision of municipal data to the public as much as possible. Moreover, if national governments can identify which municipalities adhere to which motivation perspective, they can then develop more targeted open data policies that meet the requirements of the municipalities that adhere to each perspective. This should result in more open data value creation.
