Waka is a type of traditional Japanese poetry. Waka poetry reflects the mind of waka poets. By extracting taste and feeling from waka poetry, it is possible to reveal aesthetic notions in waka poets. This work focuses on waka poetry composed by the Sanjurokkasen included in the Nijuichidaishu. We thus interpret the predicted results in the classification of waka poets by LIME. The number of waka poetry data varies from poet to poet. Therefore, we adopt Naive Bayes as the classification algorithm in this work, which is expected to have high accuracy even when the number of data is small. Using LIME enables interpretation of results in the classification of waka poets; it is possible to provide rationale words for the classification results. The study of waka poetry from the point of view of data science contributes to the development of literary study by providing objective verification of hypotheses and new findings such as previously undiscovered expressions and interpretations.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124344031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, in lectures on the basics of object-oriented programming such as java, source code with as little method splitting as possible is used in the teaching materials. It seems a consideration to avoid placing an unnecessary burden on the learners. On the other hand, as a result of the considerations, the opportunity to focus on design theory and design patterns in source code is deprived. If the source code can be provided methodized at an appropriate level, it can be used as learning material as is. This study focuses on method partitioning among refactoring principles (improving the description of source code by method partitioning is expressed as \"refactoring\") and aims to clarify the level of logical structure appropriate as a teaching material during programming learning in terms of metrics and cognitive load.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130731311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trace table is useful to facilitate understanding of object-oriented programs. Traditionally a trace table is used to facilitate understanding of a structured non-object-oriented program. We extend the notion of trace table to represent the dynamic behavior of object-oriented programs and propose a trace table generator for Java programs in this paper. The trace table is represented using an Excel file and is designed by extending the notion of the UML sequence diagram. Each worksheet of the trace table corresponds to an instance. Each column of the worksheet contains a value of the instance variables and local variables within the instance as well as message sending among the instances. Each row of the worksheet represents a sequence of steps at each method. The trace table generator is implemented using JavaParser and inserts code to the original collection of Java source codes. Various information to generate a trace table is extracted by executing the converted source code.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114662877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measuring devices and supplementary information from questionnaires or chats were previously utilized. In this study, we tested the feasibility of emotion estimation using only the heart rate obtained from a smartwatch.In the study method, participants watched a video content, focusing on the comedy content. They were asked to leave a note when they thought the content was funny. The data were processed using correlation coefficients. We then calculated the correlation coefficients between the participant’s heart rate variability and a pair of participants for all combinations. Results showed that finding a relationship between emotion and the heart rate data from the smartwatch is impossible.

Practical experience in the field of education suggests that reading aloud helps students comprehend words in their original order. Compared with silent reading, which uses only the sense of sight, reading aloud sends more complex in-formation to the brain (frontal lobe) because it increases the number of sensory organs by using the ears (hearing) as well. Moreover, there have been many studies on learning environments and teaching methods in programming language learning. A common learning method is ‘sutra-typed learning’, in which students type and execute given example pro-grams by themselves. There have been reports that students do not understand how to read and decipher the programming language in sutra-style learning.Programming languages use alphanumeric characters and numerous symbols, which are often difficult for beginners to distinguish because they do not know how to read them. If a learner does not know how to read, he or she will not be able to hear the instructor's explanations and may not be able to comprehend. Failure to communicate may hinder the instructor's ability to pro-vide appropriate instructions, leading to a decline in the learner's understanding and motivation to learn.To clarify the effectiveness of reading aloud while learning programming languages for college students majoring in informatics, this paper reports on the creation of a programming learning system using reading aloud as the first step in the learning process.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127353548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study analyzed and compared the emotions expressed by people in Japan, the United States, Great Britain, Canada, Australia, and India regarding the vaccine by analyzing tweets, on the basis of the Plutchik's wheel of emotions. In addition, a textual analysis was conducted using dependency analysis and burst detection to obtain information regarding positive changes in people’s feelings toward vaccines.
