Bubble storytelling with automated animation: a Brexit hashtag activism case study.

Abstract: Hashtag data are common and easy to acquire. Thus, they are widely used in studies and visual data storytelling. For example, a recent story by China Central Television Europe depicts Brexit as a hashtag movement displayed on an animated bubble chart. However, creating such a story is usually laborious and tedious, because narrators have to switch between different tools and discuss with different collaborators. To reduce the burden, we develop a prototype system to help explore the bubbles’ movement by automatically inserting animations connected to the storytelling of the video creators and the interaction of viewers to those videos. We demonstrate the usability of our method through both use cases and a semi-structured user study.

Patent portfolio analysis model based on legal status information

Abstract: Purpose:This research proposes a patent portfolio analysis model based on the legal status information to chart out a competitive landscape in a particular field,enabling organizations to position themselves within the overall technology landscape.Design/methodology/approach:Three indicators were selected for the proposed model:Patent grant rate,valid patents rate and patent maintenance period.The model uses legal status information to perform a qualitative evaluation of relative values of the individual patents,countries or regions’ technological capabilities and competitiveness of patent applicants.The results are visualized by a four-quadrant bubble chart To test the effectiveness of the model,it is used to present a competitive landscape in the lithium ion battery field.Findings:The model can be used to evaluate the values of the individual patents,highlight countries or regions’ positions in the field,and rank the competitiveness of patent applicants in the field.Research limitations:The model currently takes into consideration only three legal status indicators.It is actually feasible to introduce more indicators such as the reason for invalid patents and the distribution of patent maintenance time and associate them with those in the proposed model.Practical implications:Analysis of legal status information in combination of patent application information can help an organization to spot gaps in its patent claim coverage,as well as evaluate patent quality and maintenance situation of its granted patents.The study results can be used to support technology assessment,technology innovation and intellectual property management.Originality/value:Prior studies attempted to assess patent quality or competitiveness by using either single patent legal status indicator or comparative analysis of the impacts of each indicator.However,they are insufficient in presenting the combined effects of the evaluation indicators.Using our model,it appears possible to get a more complete and objective picture of the current

Using a bubble chart to enhance adherence to quality-of-care guidelines for colorectal cancer patients

Abstract: This study examines whether a higher rate of physician adherence to quality-of-care indicators for colorectal cancer patients is associated with improved survival and using a bubble chart to help interpret physician performance. A set of 13 core measures was used to evaluate the quality of care in 708 colorectal cancer patients treated from 2004 to 2007 at a hospital in Taiwan. A 100% adherence standard was used to measure the relationship of adherence to patient survival. Each indicator assigned by each cancer stage was dichotomously coded. The associations between the adherence and survival rates and demographic characteristics were assessed using Cox’s proportional hazard regression. Physician adherence to core indicators was plotted using a bubble chart to motivate physicians’ performance adhering to quality-of-care guidelines for colorectal cancer patients. The 100% adherence rate criterion contributed to a relatively low hazard ratio of 0.36 (95% confidence interval, 0.14–0.85; P = 0.02). The association between the adherence rate and survival indicated significant improvements for stage III patients compared with stage I patients. A graphical representation of bubble charts helped to monitor physician performance, which improved the adherence rate to quality-of-care guidelines for colorectal cancer patients.

Bubble chart creation method and apparatus

Abstract: The invention discloses a bubble chart creation method and apparatus. The method comprises the steps of obtaining a target data sequence, wherein the target data sequence comprises a plurality of target numerical elements; determining a plurality of target intervals according to the target numerical elements, wherein the number of the target intervals is greater than or equal to the number of the target numerical elements; establishing target mapping relationships between the target numerical elements and the target intervals according to preset rules, wherein each target numerical element corresponds to a target interval; and creating a bubble chart according to the target mapping relationships. According to the method and the apparatus, the technical problem that the display effect is influenced due to bubble overlapping in the bubble chart in related technologies is solved.
