  • This study aims to provide information about the research-trends in the area of Geospatial Information using text-mining methods. We derived the National R&D Reports and papers from NDSL(National Discovery for Science Leaders) site. And then we preprocessed their key-words and classified those in separable sectors. We investigated the appearance rates and changes of key-words for R&D reports and papers. As a result, we conformed that the researches concerning applications are increasing, while the researches dealing with systems are decreasing. Especially, with in the framework of the keyword, '3D-GIS', 'sensor' and 'service' xcept ITS are emerging. It could be helpful to investigate research items later.

  • This research explores the enhancement of park operation and management by analyzing the changing demands of park users. While traditional methods depended on surveys, there has been a recent shift towards utilizing social media data to understand park usage trends. Notably, most research has focused on text data from social media, overlooking the valuable insights from image data. Addressing this gap, our study introduces a novel method of assessing park usage using social media image data and then applies it to actual city park evaluations. A unique image analysis tool, built on Visual Question Answering (VQA) deep learning technology, was developed. This tool revealed specific city park details such as user demographics, behaviors, and locations. Our findings highlight three main points: (1) The VQA-based image analysis tool's validity was proven by matching its results with traditional text analysis outcomes. (2) VQA deep learning technology offers insights like gender, age, and usage time, which aren't accessible from text analysis alone. (3) Using VQA, we derived operational and management strategies for city parks. In conclusion, our VQA-based method offers significant methodological advancements for future park usage studies.

  • With the recent changes in society and the introduction of new technologies, the usage patterns of parks have become diverse, leading to increased complexity in park management. As a result, there is a growing demand for flexible and diverse park management that can adapt to these new requirements. However, there is inadequate discussion on these new demands and whether urban park management policies can respond. Therefore, empirical research on how park usage patterns are evolving is critical. To address this, blog data, in which individuals share their experiences, was used to examine the spatial consumption patterns through semantic network and topic analysis. This study also explored whether these spatial consumption patterns exhibit experiential consumption characteristics according to the experience economy theory. The results showed that consumption behaviors, such as renting picnic sets and having food and drinks delivered, were prominent and that emotional experiences were pursued. Furthermore, these findings were consistent with the experiential consumption characteristics of the experience economy theory. This suggests that park planning and maintenance methods need to become more flexible and diverse in response to the changing demands for park usage.

  • The purpose of this study is to investigate how Pritzker Architecture Prize as a social act has maintained an organic relationship with the architecture, the urban society through the speakings and writings of the laureates of the Pritzker Architecture Prize. The composition of this research is to grasp the background of the establishment of Pritzker Architecture Prize and the examination process, to examine its social meaning, and to identify the main flow of words from writings about the laureates through the literature survey and text frequency analysis. And is to interpret the meaning of urban society change and words about the laureates. As a result of the analysis of the flow, it is a tendency to move from ideology and style to newness and innovation, and now to publicity and sociality. Especially in recent years, a wide range of values are floated as much as the complicated issues of urban society and the natural environment. The various architectural activities that make up the urban life became more important than the building units existing like an icon. It is considered possible because the Pritzker Architecture Prize has been awarded for a sustainable common social act. In addition, through literature surveys, have also seen changes in the value of individual laureates, the mixing of styles, and the eclectic aspect. Therefore, the task of reading change should not be a process of finding a new style for a new age, but a task of acknowledging heterogeneity of each architect and recognizing diversity through pluralization.
