  • Today, opinion reviews on the Web are often used as a means of information exchange. As the importance of opinion reviews continues to grow, the number of issues for opinion spam also increases. Even though many research studies on detecting spam reviews have been conducted, some limitations of gold-standard datasets hinder research. Therefore, we introduce a new dataset called "Paraphrased Opinion Spam (POS)" that contains a new type of review spam that imitates truthful reviews. We have noticed that spammers refer to existing truthful reviews to fabricate spam reviews. To create such a seemingly truthful review spam dataset, we asked task participants to paraphrase truthful reviews to create a new deceptive review. The experiment results show that classifying our POS dataset is more difficult than classifying the existing spam datasets since the reviews in our dataset more linguistically look like truthful reviews. Also, training volume has been found to be an important factor for classification model performance.

  • The purposes of this study were to find out what attitude teachers have toward adopting ICT education to educational programs for gifted students, and how ready they are for carrying out ICT education for gifted students. For these purposes, this study surveyed 191 teachers that are currently working for gifted students in various school levels, from elementary schools to junior high and high schools. The major results of this study were as follow: (1) most teachers recognized that enhancing ICT-related capabilites of gifted students is very important, and (2) ICT-related activities in current education programs for gifted students are limited to the basic level, such as web searching for collecting information and making visual presentations using well-known commercial software. Based on the common recognition on the importance of ICT-related capabilites for gifted students, this study suggests that training teachers, as well as employing well-trained teachers, should be the first and most important step for ICT education for gifted students.

  • This study was conducted to investigate the responsiveness and its related factors of public health center for novel influenza A (H1N1) epidemic. The data was collected through a web-based survey conducted during February to April 2011. The 182 respondents were team leaders or persons who were responsible for H1N1-related work at public health centers during the H1N1 prevalence. The related factors affecting the responsiveness were different by urban or rural area. In the level of gu (urban) area, cooperation with the public organizations, preparing its own response plan were the significant factors. But, in the level of si or gun (rural) area, cooperation with private organizations (clinic or pharmacy), physical (facilities, equipments, and medicines), and human infrastructures (public health professions, education and knowledge, and motivation) were more important factors. Therefore, how to cope with H1N1 prevalence in the future should be different by local characteristics. As a result, there are several challenges that public health centers should prepare for the further emerging infectious diseases. First, it is needed to make standard manuals which could strengthen education and training in order to respond appropriately, as well as to prepare enough physical infrastructures for the crisis. Next, the public health center should prepare correct media response and cooperation system with public and private organizations.

  • This study aims to provide some rosie material for the libraries to improve its role for supporting the virtual university by recognizing the changing roles to have to support the distance education which is becoming a growing area in the coming new century due to the necessity of continuing renewal and the retaining of the information related workers. Through the study, a few conclusions were derived. (1) To support the virtual university, the library services should be directed toward the operation of the full access - philosophy and should reflect the information needs of the off-campus students. The librarians should be equipped with the ability to make use of networked resources and to provide the document delivery services together with the ability to develop the web-based user training programs. The department of library and Information Science should educate the future librarian for the purpose of supporting the virtual university. (2) A written and agreed guidelines should be established to specify the philosophy, management, facilities, resources and services to support the virtual university. And it is desirable that in the near future the department and a librarian responsible for the supporting the distance education should be established.

  • Since documents on the Web are naturally partitioned into many document databases, the efficient information retrieval (IR) process requires identifying the document databases that are most likely to provide relevant documents to the query and then querying the identified document databases. We first introduce a neural net agent for such an efficient IR, and then propose the hierarchically organized multi-agent IR system in order to scale our agent with the large number of document databases. In this system, the hierarchical organization of neural net agents reduced the total training cost at an acceptable level without degrading the IR effectiveness in terms of precision and recall. In the experiment, we introduce two neural net IR systems based on single agent approach and multi-agent approach respectively, and evaluate the performance of those systems by comparing their experimental results to those of the conventional statistical systems.

  • The purpose of this study is to develop and use the e-learning contents accessibility guidelines to improve contents accessibility for the non-technical developers and designers. The accessibility guidelines used for web or digital contents are usually technical, field dependent, or specific that are not friendly for many developers or designers. In this study, the e-Learning Contents Accessibility Guidelines was developed based on the principles of Universal Design for Learning. The guidelines could be used to map the necessary skills for the developers and the instructional designers. In this study, 5 users with different disabilities tested 6 e-learning contents, and surveyed e-learning experts to identify core elements for accessibility guidelines. Due to the limited accessibility of the contents, we need to offer manuals and training for developers and designers, need collaborative efforts between different stake holders, include accessibility in quality assurance guidelines, and further research to improve accessibility for many existing Flash contents.
