Although the scope of local materials is wide, public relations magazines issued by local governments are published by almost all municipalities in Japan．It can be considered one of the important sources of local history. The author has clarified the current status of digitization and openness of PR magazines through surveys of municipal websites, library OPACs, and WARP of the National Diet Library, among others. In this study, individual departments in charge of local governments were surveyed about their thoughts on the digitization and openness of their PR magazines. It was revealed that the concept of digitization and openness of PR magazines varied greatly among municipalities.

　Public administration is in the process of formulating web accessibility policies and disclosing test results. According to a survey by the Web Accessibility Infrastructure Committee, as of 2019, 46 organizations had already formulated policies in 47 prefectures, and 40 organizations had published test results. In 20 ordinance-designated cities, 20 organizations have already formulated policies, and 19 organizations have disclosed the test results. Since the survey is up to date in 2019, this study will investigate the situation in 2022.

　To utilize quantitative relationship among physical quantities represented in mathematical formula in science texts, an effort to extract mathematical formula, variables in them, and the physical meanings of the variables by computer program was made. Three methods, rule-base, parsing + rule-base, and deep learning were tried to extract physical meanings of the variables. It was revealed that rule-base methods with/without parsing require further machine learning even after rules were applied, which results in unrealistic huge tasks. Deep learning using BERT fine-tuning with 4000 – 4500 labeled data achieved more than 70 % accuracy.

　"Koji-Ruien" was compiled 36 years after its proposal in 1879.It still occupies the position of Japan's largest encyclopedia. The presenter has been working with the collaborators to create a full-text database of the book. At the same time, we have repeated analysis and ingenuity to make "Koji-Ruien" itself a meaningful research subject.Specifically, it is as follows. I will report on the outline and current status of these efforts.
1. Efficient input and calibration methods.
2. Apply the classification system applied to "Koji-Ruien".
3. Identify and compare the cited originals.
4. Adopted "Aozora Bunko" format with abundant support tools for data sharing.

　With respect to the VR art museum created by students, I first describe the generation of paintings colored with AI on both sides of the student and teacher's side. By dealing with the Software AI Picture Branch, students can make paintings that are easy to understand for anyone who is not good at painting, making them easier to communicate to others. In contrast, there are some teachers who do not understand the theme of the entire painting from the viewpoint of the evaluation of painting, and they cannot evaluate them. The process of creating the VR Museum was organized by incorporating these opinions.

　Web of Science and Scopus are well-known services that provide the research community with helpful information, such as research metrics, based on their database of research papers and citations, etc. Another type of academic information infrastructure is built by the research community, aggregating open access research products. Both types of services provide statistics and other information to the community through dashboards in recent years. This paper compared and analyzed six dashboards generated from four major worldwide academic information infrastructures. By classifying the indicators on the dashboards, the characteristics of each service were clarified. Research metrics and open science-related metrics stand out on commercial and academic dashboards, respectively. Also, new indicators were observed on both types of dashboards.

The demand for academic information retrieval services is increasing due to the growing trend toward more active research data sharing and reexamination of research evaluation, but the constituent functions of these services are not clear. Therefore, this study focused on the screen functions of 59 domestic and foreign academic information retrieval services. We extracted and itemized the functions from these services, and conducted a comparative analysis. The itemization yielded 31 items, which were expressed as a 0/1 vector according to the presence or absence of the corresponding function. In this report, we describe the quantitative analysis based on the item vectors and the characteristics obtained by observing each service.

　In narratology, various structures such as scene sequences and human relationships are the targets of analysis, but a unified format is desirable for quantitative operations by computers. In this research, a method to describe a story as a hierarchical structure consisting of three major layers of story, quest, and scene is proposed. This is based on the knowledge about various structures of the stories obtained by the previous researches. By using the three-layer structure, it is possible to describe not only the scene sequences but also the characters and events in the story in a unified format.

　This study clarified the support needed for blind people to enjoy video games through practice using the Super Nintendo Entertainment System. After examining the three software, it was found that blind people can play the game with little or no assistance, depending on the configuration and added audio information. We also found the possibility that both blind and sighted people can enjoy the game with minimal assistance from sighted people.

　In order to promote open access by Japan’s institutional repositories, libraries have been asking researchers to provide articles. However, since its advantage is unclear, the success rate of the activity has been stagnant. Considering the situation, this study examined whether the advantage exists, focusing on citations. Although the number of open access articles by Japan’s institutional repositories is limited, a comparison of their citations with those of various types of open access articles did not confirm the advantage.

　This research focuses on a series of broadcast programs, compares and examines a wide range of elements such as URLs included in program information, and shows effective methods for identification. The proposed method considers the matching method for each field and the combinations between them. A series identification method was proposed on condition that either of two fold was satisfied, one condition sets the delimiter and matches the master title extracted from the title exactly. The other condition extracts the URL from the program details and matches it with considering the Jaro-Winkler distance to the title. Then, We created an evaluation dataset for 35 days of program information from September to October 2021, and the method was evaluated using the number of series, the precision and recall of the broadcast program pairs as metrics. The results showed that the method using the master title extracted from the title is effective. In addition, the results indicated that adding the Jaro-Winkler distance is useful for improving the accuracy of the identification condition by URL.

　The purpose of this study is to facilitate the discovery of songs through effective browsing search. We propose a method of presenting similar songs with the relationships among them. In order to achieve this, we used a portion of the music data provided by Spotify API to calculate similarity using Euclidean distance. When a user select a song as the starting point of the search, our method extracted the top similar songs, and visualized them using a graph layout dynamics model.

　The mechanism that makes readers feel a ‘Tokimeki’ in a story has not been little studied to date. In this study, analysis of the structure and extraction of scenes related to ‘Tokimeki’ were conducted to identify characteristics related to ‘Tokimeki’ by using dating simulation games for women, which are presumed to emphasize the ‘Tokimeki’ mechanism in the story. The study revealed that there are three major patterns of ‘Tokimeki’ by comparing the narrative structure of each male character.

　Narrative study has traditionally been conducted extensively, and research on ghost stories, a genre of stories, has also been conducted on book works. In recent years, ghost stories have been distributed not only as book works but also as web works posted on the Internet. In this study, we conducted a narrative structure analysis focusing on ghost stories posted on the Internet. In addition, by comparing the narrative structure of book ghost stories analyzed in previous study, we clarified the differences in the narrative structure of ghost stories in different media.

　Programming education is offered at many universities. A class for the first-year students of the Faculty of Systems Engineering, Wakayama University, supplies a shakyo-style learning support system. However, it has been not clear whether students truly acquire programming skills through classes. In this study, we constructed an online judging system using a web application. By embedding the edit screen of another Web service in the answer screen, users can create a program, check its operation, and submit the answer on a single screen. In the final session of an introductory programming class, a variety of correct and incorrect answers were submitted for a question that required a program whose output is a specific string 10 times. Moreover, we attempted to reconcile the answers with the pros and cons of the non-necessity of the for statement questioned in the middle of the class.

　Narrative research on Fan Fiction has been conducted mainly on works that are based on the same original story. Comparative analysis of fan fiction groups with different original stories to see if there were any differences or common characteristics between fan. As a result, we found some characteristic story types of fan fiction, such as "negative death" type, "character relationship transition" type, and "meme fixation" type, which are common to both groups of works.

　There have been few attempts to quantitatively analyze the rhetoric and stylistic characteristics of Japanese essays other than the metaphors used. In this study, in order to identify the rhetoric used by different authors in different essays and the rhetoric suitable for each theme of the essay, we compiled data on the rhetoric used. Based on the data obtained, the characteristics of the rhetoric used in the essays were quantitatively extracted. The results revealed the rhetoric used by each author based on his or her strategy.
