  • This paper discusses a new weighting method for text analyzing from the view point of supervised learning. The term frequency and inverse term frequency measure (tf-idf measure) is famous weighting method for information retrieval, and this method can be used for text analyzing either. However, it is an experimental weighting method for information retrieval whose effectiveness is not clarified from the theoretical viewpoints. Therefore, other effective weighting measure may be obtained for document classification problems. In this study, we propose the optimal weighting method for document classification problems from the view point of supervised learning. The proposed measure is more suitable for the text classification problem as used training data than the tf-idf measure. The effectiveness of our proposal is clarified by simulation experiments for the text classification problems of newspaper article and the customer review which is posted on the web site.

  • The purpose of this paper is to examine the basic principles for the examination of documents in terms of the basic duty to examine the documents, the time allowed to the banks to examine the documents, linkage among the documents, the originality of documents and their issuers, and the rejection formula of documents. Further this author would look at the changes of particular transport document including bill of lading, charter-party bill of lading and so on. From the seller's perspective, the changes of the principles and individual documents under UCP600 are the most important in the sense that they affect the criteria against which the payment is made. The major changes include the omission of the phrase "with reasonable care", in terms of the basic examination principles, substitute the phrase "five banking days following the day of presentation" for the phrase "reasonable time, not to exceed seven banking days following the days of receipt of documents", introduce the new wording about the linkage between the documents tendered, and make clear the meaning of the originality of documents as well as the rejection formula. For transport documents, even though dealing with bill of lading, charter-party bill of lading, transport document covering at least two different modes of transport, freight-forwarder bill of lading and freight collect transport documents, this paper focuses on the "transhipment" of bill of lading and the definition of charter-party bill of lading. Thus, UCP has been changed several times to reflect the new banking customs and practice. It, however, would not answer every questions which users and banks will raise. These questions may be best answered in the particular underlying contract. The UCP are necessary but not a sufficient instrument for the smooth operation of an international trade transaction. The rules are now out: it remains to be seen what the players do with it.

  • A bill of lading is a document which is signed by the carrier or his agent acknowledging that the goods have been shipped on board a named vessel bound for the destination and stating the terms on which the goods so received are to be carried. Therefore, the bill of lading is a document of title enabling the holder to obtain credit from banks before the arrival of the goods, for the transfer of the bill of lading can operate as a pledge of the goods themselves. In the other words the bill of lading creates a privity between its holder and the carrier as if the contract was made. A bill of lading, for obtaining credit from banks, must appear to indicate the carrier's name and signature, the "shipped on board" notation, the port of loading and unloading stated in the sales contract and the credit. Data in the bill of lading, when read in context with the sales contract, the credit, the bill of lading itself and international standard banking practice, need not be identical to, but must not conflict with, data in that bill of lading, any other stipulated document, the sales contract or the credit. The surrender bill of lading, stamping "surrendered" on the original bill of lading by request of the shipper, is not recognized the legal effectiveness as a document of title by the statutory law and court. The surrender bill of lading may increase the risk of impossibility of payment to the holder. Therefore, the surrender bill of lading should be used restrictively between the credible parties and suggested to avoid in the other cases.

  • With the development of the Internet, users share their experiences and opinions. Since related keywords are used witho0ut considering information such as the general emotion or genre of an unstructured document such as a movie review, the sensitivity accuracy according to the appropriate emotional situation is impaired. Therefore, we propose a system that predicts emotions based on information such as the genre to which the unstructured document created by users belongs or overall emotions. First, representative keyword related to emotion sets such as Joy, Anger, Fear, and Sadness are extracted from the unstructured document, and the normalized weights of the emotional feature words and information of the unstructured document are trained in a system that combines CNN and LSTM as a training set. Finally, by testing the refined words extracted through movie information, morpheme analyzer and n-gram, emoticons, and emojis, it was shown that the accuracy of emotion prediction using emotions and F-measure were improved. The proposed prediction system can predict sentiment appropriately according to the situation by avoiding the error of judging negative due to the use of sad words in sad movies and scary words in horror movies.

  • UCP 600 approved at the Banking Commission Meeting of ICC at the end of October, 2006 comes into effect from July 1, 2007. The main revision of the UCP 600 concerning the sea transport document are as follows. First, if the bill of lading contains an on-board-notation, with the date of shipment, the date stated in the on-board-notation will be deemed the date of shipment. Secondly, phrases "on its face" and "otherwise authenticated" should be eliminated. Thirdly, when an agent signs for or signs on behalf of the master, there is no longer a need for the name of master to be quoted. Fourthly, the terminology "loading on-board or shipped on a named vessel" is changed to "shipped on-board a named vessel." Fifthly, phrases "the rejection of the documents transported only by sail" is removed. Finally, new rule in UCP is the signing of a charter party bill of lading by the charterer or a named agent on behalf of the charterer. My assessment of the revision in UCP 600 is as follows: Because a freight forwarder transport document is a weaker form than a liner bill of lading as collateral, banks may need a secure measure as to protect themselves from such a weak collateral effect. we recognize that Such a weak collateral effect stemmed from the elimination of rules in UCP 500 article 30, and the admission of transport documents issued by the freight forwarder as long as any one besides carrier, shipper, and charterer satisfies the requirements of transport document clauses in UCP 600. Finally, I hope the Commentary on UCP 600 will serve to explain the ambiguities remaining in the new rules.

  • Multi-document refers to a document consisting of various topics, not a single topic, and a typical example is online reviews. There have been several attempts to summarize online reviews because of their vast amounts of information. However, collective summarization of reviews through existing summary models creates a problem of losing the various topics that make up the reviews. Therefore, in this paper, we present method to summarize the review with minimal loss of the topic. The proposed method classify reviews through processes such as preprocessing, importance evaluation, embedding substitution using BERT, and embedding clustering. Furthermore, the classified sentences generate the final summary using the trained Transformer summary model. The performance evaluation of the proposed model was compared by evaluating the existing summary model, seq2seq model, and the cosine similarity with the ROUGE score, and performed a high performance summary compared to the existing summary model.

  • In this paper, we propose a method to classify movie review documents into positive or negative opinions. There are several approaches to classify documents. The previous studies, however, used only a single classifier for the classification task. We describe a multiple classifier for the review document classification task. The method consists of three classifiers based on SVMs, ME and score calculation. We apply two voting methods and SVMs to the integration process of single classifiers. The integrated methods improved the accuracy as compared with the three single classifiers. The experimental results show the effectiveness of our method.

  • Studies on online review have carried out analysis of the rating and topic as a whole. However, it is necessary to analyze opinions on various dimensions of service quality. This study classifies reviews of healthcare services into service quality dimensions, and proposes a method to identify words that are mainly referred to in each dimension. Service quality was based on the dimensions provided by SERVQUAL, and patient reviews have collected from NHSChoice. The 2,000 sentences sampled were classified into service quality dimension of SERVQUAL and a method of extracting important keywords from sentences by service quality dimension was suggested. The RAKE algorithm is used to extract key words from a single document and an index is considered to consider frequently used words in various documents. Since we need to identify key words in various reviews, we have considered frequency and discrimination (IDF) at the same time, rather than identifying key words based only on the RAKE score. In SERVQUAL dimension, we identified the words that patients mentioned mainly, and also identified the words that patients mainly refer to by review rating.

  • The purpose of the study is to suggest ways to improve the Landscape Review system and Landscape Management System of Jeju Special Self-governing Province through Analysis of the Landscape Review Results and Jeju Special Self-governing Ordinance. For this purpose, the research methods were reviewed for preliminary study and reviewing the laws and ordinances related to landscape, and 318 cases of landscape review, which have been implemented since 2010, were analyzed by item by item along with the result of the review. The main results of the analysis are as follows. First, Jeju Special Self-governing Province, which currently operates an enhanced ordinance of development project review, is experiencing problems such as building the wrong construction projects due to the weak legal basis for follow-up management after landscape Review. Second, Jeju Special Self-governing Province expects efficient management of the province through expansion of the scope of the landscape review. Third, the current status of the decisions by the Landscape review showed that 57.7% of the bills passed, the lowest at 41.9% for the development projects. Fourth, analysis of the landscape review contents by categorization by item showed that ' Landscape Control Guideline' and 'Document not completed' are relatively high. Thus, eight years have passed since the start of the Landscape Management System and the Landscape Review, but systematic institutional stability is not sufficient, so it is necessary to make the Landscape Control Guideline easier to understand.
