• W157241015 abstract "Open data can become available by open data infrastructures. In recent years, different governmental and private organizations have published their data through open data platforms to accelerate knowledge and information sharing. They are open data platforms, which are not particularly developed by any public or private organization. These universal open data platforms facilitate combining data various data types from different data resources. The aim of this study is to create integrated user interfaces for different groups of users, which stimulate services for users Open Data (OD), including the processes of importing, curating, processing and visualizing OD. The process of Open Data consists of following steps; Data production, publish data, Look for data, use data, feedback. The process focuses on providing data that are not accessible, to be published. For this research, various research methods were used: literature research has been conducted. Next we followed requirements engineering approach to elicit and analyze requirements by using scenario and use case techniques. We have created prototypes by visualizing use case flows in BPMN diagram. Finally, we have conducted an evaluation by user testing in the scenario-based environment, and walk-through technique. In this research, we focus on technological barrier of open data. Many technological impediments restrict users to have easy access to open data. The most significant impediments are Data deposit, Data access and Data use, impediments. Also, different requirements are identified for open data platforms. These requirements are categorized in five subcategories. Namely, Standardization, API, Materialization, Policies and integration. Data publishers usually only make data available and often do not consider the user perspective. One aspect of the user perspective that has received very little attention is the user interface of open data platforms. We have performed requirements analysis by using scenario and use case techniques. We have designed 6 scenarios that cover all steps of open data process. Next, we have created BPMN diagram to represent the flow of use cases. Finally, we have created UI mockups for Open Data platform. This research contributes in adding more benefits from open data by designing the user interface to increase the user’s contribution, as well as contributing into studies in the field of open data. This research involved a usability test in scenario-based environment as well as inspection. A total of 16 usability tests was conducted. The usability test was intended to verify the proposed UI. Participants were selected from different age ranges, countries, and study fields. Therefore, we conclude that users’ success rates (performing tasks correctly) with the all the three scenarios were considerably high. However, a disadvantage regarding the dataset extension is reported. Lastly, most of the tasks were performed correctly and according to users most of the tasks were easy to perform." @default.
