However, only a limited number of CEFR studies for learners of the Japanese language have been conducted. Some of them focused on the classification of Japanese example sentences into the corresponding CEFR reading comprehension indices using three inference features: length, document type, and technicality. In this study, we add seven new CDSs to the Pre-A1 level published in the CEFR Companion Volume with New Descriptors in 2017 and perform experiments to classify the CDSs. In line with the incorporation of the new CDSs, we used a new feature called Kanji rate along with the three inference features as vital indexes for assessing Japanese reading comprehension. Experimental results are presented in the study. The purpose of this study is to help teachers on site use CEFR to evaluate the Japanese language proficiency of learners. Our ultimate goal is to create a Japanese CEFR-compliant text corpus.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121891878","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}

It is thought that ambiguous sentences are sentences that do not express tacit knowledge sufficiently, and it expect that the diagram will help to extract tacit knowledge by considering the presence or absence of ambiguity complementation. As a result, it was found that figures and tables have a role of complementing the ambiguity of ambiguous sentences, and the number of figures and tables is proportional to the number of ambiguous sentences. Furthermore, it was found that a figure far from the ambiguous sentence was also used to resolve the ambiguity.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123562347","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}

Since web users generally state their opinion in various languages, it is important to develop a method of multilingual sentiment analysis for web texts. In this research, we design a multilingual sentiment analysis method based on word to word translation using a sentiment dictionary in arbitrary native language. This method consists of three phases: morphological analysis of text, a sentiment extraction of each word with sentiment dictionary, and a sentiment extraction of text based on words sentiments. We conduct a sentiment classification experiment for tweets in English, German, French, and Spanish. In the experiment, we evaluate our classifier’s performance by comparing the classifier with the other previous classifiers based on the evaluation standards \"Accuracy\", \"Precision\", \"Recall\", and \"F1 score\". The experimental results show that our classifier has an applicability to sentiment analysis for multilingual, because our classifier’s performance is independent of the differences languages.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125013976","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}

We present the measurements of global competency based on a case study of the Shibaura Institute of Technology from the role of Institutional Research (IR). In 2019, we conducted a pilot survey to measure the effects of the global competency of study abroad programs. As Suskie (2014) argues, Institutional Researchers have capacity measuring competencies on co-curricular activities such as study abroad programs. According to her, there are five advantages of the IR to measure competencies as their role. These are (1) based on the mission and policy of the institutions, (2) not only students, but also alumni, employers, regional society, (3) across the institutional culture of silos, (4) with appropriately and systematically, and (5) effective improvement of the program.

Specifically, SciBERT and BioBERT, which are specialized in the science and technology fields, are used in the method.

To enjoy these merits, effective compaction of sensing data, energy efficient networking, and edge oriented data management architecture has been proposed.

Knowing tourist interests and wayfinding decision-making affect tourists routes and facilities since the planners and hotel facilities will do planning their hospitality and every service plans using their information. To make the model of the tourist movements, an effective mathematical description will be expected for their systematic analysis. In this paper, Markov process model of the tourist movements are newly developed using information theory. Then, it is shown that the order of Markov process of the movements is estimated using conditional entropies, efficiently and the shuffling operation of Markov process is newly proposed to verify conditional entropies of the Markov process. The stochastic simulation model based on the analysis is useful for the verification of the Markov process with the estimated order of the behavior of tourists movement.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129123465","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}

Kobe Tokiwa University constructed the course based on 19 Tokiwa competencies. In order to evaluate the students, who are evaluated by the 20 teachers based on Tokiwa competencies, we constructed a rubric and an evaluation matrix for the first-year course. Our study attempts to address the following research question: Is our evaluation matrix, which is based on the Tokiwa competencies used by teachers to evaluate the students in the 2018 first-year course, a good evaluation tool. To answer this research question, we performed a factor analysis of the evaluation of students by using an evaluation matrix for the 2018 first-year course. The results show that our evaluation is not based on the Tokiwa competencies. Therefore, we constructed a new evaluation matrix for the first-year course.
