While specializing in the limited field and aiming at a high share, a scale is secured aimed at the world market. This strategy attracts attention for small and medium-sized enterprises whose management resources are restricted. However, since those companies have various target fields, understanding the common success factor only by analyzing each example is difficult. Moreover, it is difficult for a selection-type questionnaire to understand the success factor in various fields. In this study, we attempted to clarify success factors by analyzing the free description data written about GNT companies using text mining. As a result, information related to success factors of various types of industries was acquired.","PeriodicalId":272739,"journal":{"name":"2016 5th IIAI International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129982490","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 bounded-SVD bias, the bound constraints are included in the objective function, which ensures that they are satisfied during the optimization process. As shown in one of our previous work, this helps bounded-SVD bias outperform an existing MF method with bound constraints, called Bounded Matrix Factorization. However, there is one issue with bounded-SVD bias that it is prone to overfitting. In this work, we introduce a new term to the objective function of bounded-SVD bias that can help it avoid overfitting. We also perform various experiments using real-world datasets, the results of which show an improvement in terms of accuracy and thus the superiority of the proposed method.","PeriodicalId":272739,"journal":{"name":"2016 5th IIAI International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130512953","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 constructed the system for improving speaking proficiency based on Web-Speech API. Usually, text-to-speech is available on the net or by using TTS applications in education. However, these sounds produced are not generally customized to the diversity of learners' learning strategies. The system constructed in the study makes it possible for learners to choose the words, phrases sentences or the passage they like to listen to for their speaking practice. Major findings that came out from this study are: (i) As to the easier materials, accuracy improvement was observed regardless of their proficiency, (ii) On the contrary, as to the difficult materials, such an improvement was not observed in the experiment, and (iii) there is diversity of how they worked on the system, and there are some patterns in their learning behaviors, Bottom-uppers and Top-downers. These findings suggest the usefulness of the current system for various types of learners in terms of learning strategies and a future possibility from a learning analytic point of view to modify the system.","PeriodicalId":272739,"journal":{"name":"2016 5th IIAI International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"239 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121983037","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}

Several approaches have been proposed to achieve effective IoT communications, where each device has very limited communication capabilities. One such approach is the introduction of short packets for a lightweight communication protocol by which we can form a local area sensor network dedicated to IoT devices and can achieve effective packet processing, reducing power consumption, and minimizing bandwidth occupancy. The short packet can solve problems regarding local networks but creates another problem for the wide area Internet, where various devices and local networks are converged. We propose an aggregation scheme that makes it possible to reduce power consumption and packet processing loads caused by a huge amount of short packets. We focus on the wide area Internet with our proposed scheme to support IoT traffic more efficiently.","PeriodicalId":272739,"journal":{"name":"2016 5th IIAI International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123934456","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}
