최근 들어 SNS가 대중화됨에 따라, 이들로 부터 오피니언을 분석하여 특정 이슈에 대한 여론을 파악하려는 다양한 연구가 진행되고 있다. SNS 환경에서 오피니언 분석을 위해서는 우선 게시글 중에서 오피니언 문서와 그렇지 않은 문서(객관적 문서)를 분리해야한다. 본 논문에서는 트위터 문서로 부터 오피니언 문서만을 추출하는 새로운 방법을 제안한다. 트위터 환경에서 오피니언 문서에 대한 분류나 검색의 어려운 점은 충분한 학습 자료가 존재하지 않다는데 있다 이를 위해 제안된 방법에서는 감성 분류를 위해 트위터와 유사한 외부의 정보를 이용하여 기계학습기반 분류 모델을 생성하고, 이를 응용하여 트위터에서의 오피니언 문서 추출에 적용하였다. 또한 실험을 통하여 제안된 방법의 적용 가능성을 평가하였다.

A web robot is a software that has abilities of tracking and collecting web documents on the Internet(l), The performance scalability of recent web robots reached the limit CIS the number of web documents on the internet has increased sharply as the rapid growth of the Internet continues, Accordingly, it is strongly demanded to study on the performance scalability in searching and collecting documents on the web. 'Design of web robot based on Multi-Agent to speed up documents collection ' rather than 'Sequentially executing Web Robot based on the existing Fork-Join method' and the results of analysis on its performance scalability is presented in the thesis, For collection speedup, a Multi-Agent based web robot performs the independent process for inactive URL ('Dead-links' URL), which is caused by overloaded web documents, temporary network or web-server disturbance, after dividing them into each agent. The agents consist of four component; Loader, Extractor, Active URL Scanner and inactive URL Scanner. The thesis models a Multi-Agent based web robot based on 'Amdahl's Law' to speed up documents collection, introduces a numerical formula for collection speedup, and verifies its performance improvement by comparing data from the formula with data from experiments based on the formula. Moreover, 'Dynamic URL Partition algorithm' is introduced and realized to minimize the workload of the web server by maximizing a interval of the web server which can be a collection target.

Seller's obligation on the Delivery of Goods and Handing over the Documents are key elements in Contracts for the International Sale of Goods. The United Nations Convention on Contracts for the International Sale of Goods(CISG) has been entered into force on 1 January 1988 to create international certainty and uniformity in the law and to govern issues that arise in an international sale of goods transaction. The Incoterms were first published by the ICC in 1936 and were most recently revised in 2010. Incoterms 2010 are entering into force on 1 January 2011. The Incoterms focus on the seller's delivery obligations and reflect the principle that the risk of loss or damage to the goods passes from the seller to the buyer when the seller has fulfilled its obligations to deliver the goods. This study highlights basic rules covering seller's obligation of delivery of goods and handing over the documents under the Incoterms 2010 and the United Nations Convention and Contracts for the International Sale of Goods. In the second chapter, this study will provide analyses and compare these two legal systems in relation to the basic rules governing delivery of goods and passing of risks in contract of sale. This chapter evaluates the meaning of Article 31 and Article 67(1) and FOB, CFR, CIF & FCA, CPT, CIP terms of Incoterms 2010. Chapter Three will focus on handing over the documents. Article 30 CISG imposes the seller's primary obligations to deliver the goods and to hand over documents relating to them. Article 34 CISG supplements the seller's obligation in relation to documents by providing that the seller must hand over documents relating to the goods. In contrast, Article 58(1) CISG imposes on the buyer the obligation to pay only when it has received the goods or documents controlling their disposition. I reviewed only some of the documents relating to the goods are documents controlling their disposition. This chapter considers the meaning of the phrase "documents that control the disposition of the goods and do not control disposition of the goods." Finally, the fourth chapter will assess the meaning of rules of CISG and Incoterms 2010.

Recently there are many researches of text mining to find interesting patterns or association rules from mass textual documents. However, the words extracted from informal documents are tend to be irregular and there are too many general words, so if we use pre-exist method, we would have difficulty in retrieving knowledge information effectively. In this paper, we propose a new feature extraction method to classify mass documents using association rule based on unsupervised learning technique. In experiment, we show the efficiency of suggested method by extracting features and classifying of documents.

문헌간 유사도를 자질로 사용하는 분류기에서 미분류 문헌을 학습에 활용하여 분류 성능을 높이는 방안을 모색해 보았다. 자동분류를 위해서 다량의 학습문헌을 수작업으로 확보하는 것은 많은 비기 들기 때문에 미분류 문헌의 활용은 실용적인 면에서 중요하다. 미분류 문헌을 활용하는 준지도학습 알고리즘은 대부분 수작업으로 분류된 문헌을 학습데이터로 삼아서 미분류 문헌을 분류하는 첫 번째 단계와, 수작업으로 분류된 문헌과 자동으로 분류된 문헌을 모두 학습 데이터로 삼아서 분류기를 학습시키는 두 번째 단계로 구성된다. 이 논문에서는 문헌간 유사도 자질을 적용하는 상황을 고려하여 두 가지 준지도학습 알고리즘을 검토하였다. 이중에서 1단계 준지도학습 방식은 미분류 문헌을 문헌유사도 자질 생성에만 활용하므로 간단하며, 2단계 준지도학습 방식은 미분류 문헌을 문헌유사도 자질생성과 함께 학습 예제로도 활용하는 알고리즘이다. 지지벡터기계와 나이브베이즈 분류기를 이용한 실험 결과, 두 가지 준지도학습 방식 모두 미분류 문헌을 활용하지 않는 지도학습 방식보다 높은 성능을 보이는 것으로 나타났다. 특히 실행효율을 고려한다면 제안된 1단계 준지도학습 방식이 미분류 문헌을 활용하여 분류 성능을 높일 수 있는 좋은 방안이라는 결론을 얻었다.

This Study analyzes the fact that whether or not, the applicant, by failing to object promptly to the facial discrepancies of the presented documents and to return those documents to the issuing bank, has waived his right to sue for breach of the Application agreement based on the recent Korea-US Case law. Some commentators claim that an applicant has a duty to notify the issuing bank within a reasonable time after receiving the documents that they do not comply with the letter of credit requirements and to return those documents to the issuing bank, and also suggest that a failure to do so result in a waiver of discrepancies that operates as a matter of law. But such decisions make little sense in letter of credit transaction. Unless otherwise agreed, Applicant agreement does not require that the applicant notify the issuing bank of any facial discrepancies of the documents or return those documents. Moreover there is no support in the body of law, i.e., UCP 500 or the Revised UCC Article 5, for an automatic waiver or preclusion arising from the applicant's failure to object promptly. In addition, beyond the lack of authority to support an automatic waiver arising from the applicant's failure to object and return the documents, in a letter of credit transaction the issuing bank is the only party charged with the duty of scrutinizing documents. Therefore, if there are discrepancies, it is the bank that should have to seek an express waiver from the applicant ; the issuing bank should not avoid responsibility for failing to notice discrepancies because the applicant was slow to scrutinize the documents closely or because the applicant failed to inform the issuing bank of such discrepancies. Requiring that applicants inspect documents independently defeats the purpose of retaining the issuing bank, erodes the bank's responsibility to perform its role diligently, and may result in the bank avoiding liability despite negligent payment. If the bank wants to require an applicant to report discrepancies promptly, he may include a provision in the Application agreement limiting the time limit within which the applicant must give notice of facial discrepancies and return the documents. This approach will ensure the continued wide-spread use of documentary credit as a reliable payment mechanism.

This research attempts to verify the hypothesis that the workers in the small-and medium-sized industries use more informal information channels than formal ones do to get the information necessary to industrial activities. Information sources are divided by the internal and the external ones and these are sub-divided by their acquiring channels, publishers and holding institutions. It is intended to investigate the information sources according to the use frequency, age, origin and format of documents used. The degree of benefit to the workers in their practical work through the use of information sources and the use frequency of information sources by the department and years of experience are also investigated. The data to test the hypothesis was collected through the questionnaires distributed to the workers in 300 sampled firms from June 5 to June 20, The following facts have been verified as the result : 1. Workers in industries acquire information mainly through the contacts with the colleagues or superiors in their departments, and the junior workers depend more on the colleague and superiors than senior workers are. 2. Among the documents published internally, the ones from the research and development departments are mostly used. The documents issued by the worker's own departments are also frequently used and the senior workers, the more frequently use the internal publications than the junior workers do. 3. Among the internal documents stored in various places in the industries, the documents kept in the worker's own departments are used most frequently. The senior workers the more use privately owned documents than the junior workers do. 4. As far as the external channels are concerned, information is obtained mainly through suppliers of equipment and raw materials and the use frequency of information channels varies according to department. The senior workers the more receive information through supporting institution, seminar and exhibition than the junior workers do. 5. Among the external publication, the ones published by the industrial supporting institutions are heavily used and the workers in research and developments frequently use the external publications. 6. The documents held in governmental industrial institutions and industrial supporting institutions are heavily used compared with the ones stored in other external institutions. The holding places of frequently used documents vary according to the working departments. 7. The degree of benefit to practical work performance resulted from the internal information use is less than by the use of external information. 8. The documents published more than five years ago are more used than the ones of less than five years, Korean and Japanese documents are used frequently and catalogues, patents and standards are used to a great extent. The documents are used differently in accordance with work departments.
