  • To evaluate the performance of the question and answer services provided through the internet portals in Korea, question and answer transcript of four major services were sampled systematically. Using the digital reference evaluation framework, number and types of questions, response rate, timeliness, accuracy for information questions and user satisfaction were measured and analyzed. The level of the service performance is identified and compared. The conclusion includes suggestions for service improvement.

  • The purpose of this research is to analyze cognitive demands, answer types, and storytelling types on the basis of mathematical tasks in five different mathematics textbooks based on 2009 revised curriculum in order to suggest directions for the development and use of storytelling mathematics textbooks in school. Results show that first, PNC (Procedures without Connections) task was the largest category in cognitive demands of all mathematical tasks, Low-Level task was larger than others in cognitive demands of mathematical content tasks, and High-Level task was larger than others in cognitive demands of mathematical activity tasks. Second, a short-answer type was the largest category in answer types of all mathematical tasks, the majority of mathematical content tasks were a short-answer type, and the majority of mathematical activity tasks were both short-answer and explanation-answer types. Finally, storytelling connected to real-life was the largest category in storytelling types, and the number of mathematical activity tasks was less than that of mathematical content tasks. However, in the tasks reflected on storytelling, the percentage of mathematical activity tasks was higher than that of mathematical content tasks. Based on the results, while developing storytelling mathematics textbooks and using storytelling textbooks in school, it suggests to consider the need for balance and diversity in cognitive demands, answer types, and storytelling types according to mathematical tasks.

  • This study was conducted survey on fruit and vegetables farms (FM), consulting companies (CC), and the consultants (CT) to investigation actual conditions and improvements in consulting part of horticulture. In results of survey on FM, FM chose 'necessity' on consulting for learning of production skill and 'field visit' in means of consulting. FM had a low trust on experience and knowledge of CT and answered that FM had not enough time for consulting by reason of over-work of CT, chose 'necessity' on crop registration system. In results of common questions among FM, CC, and CT, same answer of questions were term of contract (answer: yearly contract), means of consulting (answer: visit), consulting time per a visit (answer: $2{\sim}3$hours). Different answer between supplier (CC, CT) and consumer of consulting were decision method of contract price (answer: provisional contract$\neq$contents and the quality of consulting), percentage of government subsidy (answer: propriety$\neq$step-up).

  • This study tried to describe how to give learners a quick response and to relieve instructors from burdens of answering questions. It adds more dynamic functions to Question and Answer Bulletin Board System, which plays an important role in the interaction of web-based instruction. It also causes increasing enhancements of interaction on web-based instruction. The Implemented Dynamic Question and Answer Bulletin Board System supplemented the defects of the established Q&A, in which learners should wait for answers until instructors checked questions and gave their replies. This new system enabled students to receive prompt answers by using the answer database which instructors had already installed with the result examined by internet searching engines.

  • This study aims to suggest an effective way to enhance question-answer(QA) document retrieval performance by reconstructing queries based on the structural features in the QA documents. QA documents are a structured document which consists of three components : question from a questioner, short description on the question, answers chosen by the questioner. The study proposes the methods to reconstruct a new query using by two major structural parts, question and answer, and examines which component of a QA document could contribute to improve query performance. The major finding in this study is that to use answer document set is the most effective for reconstructing a new query. That is, queries reconstructed based on terms appeared on the answer document set provide the most relevant search results with reducing redundancy of retrieved documents.

  • In this research, we have developed a "computer tutor" that mimics the human tutor with animated tutoring dialog agent and the agent was integrated to teaching-learning material for elementary science subject. The developed system is a natural language based teaching-learning system using one-to-one dialogue. The developed pedagogical dialogue teaching-learning system analysis student's answer then provides appropriate answer or questions after comparing the student's answer with elementary school level achievement. When the agent gives either question or answer it uses the TTS(Text-to-Speech) function. Also the agent has an animated human tutor face for providing more human like feedback. The developed dialogue interface has been applied to 64 6th grade students. The test results show that the test group's average score is higher than the control group by 10.797. This shows that unlike conventional web courseware, our approach that "ask-answer" process and the animated character, which has human tutor's emotional expression, attracts students and helps to immerse to the courseware.

  • When processing a query in a conventional database systems, a set of facts or tuples are usually returned as an answer. This also applies to object -oriented database where a set of objects is returned. Deductive database systems, however, provide the opportunity to obtain the answer of a query as a set of formulas, thereby reduce the costs to process the query, and represent its "intensional answers" in a more compact way independently of the database state. In this paper, by introducing rules info the object-oriented database systems and integrating the intensional query processing of deductive database systems into talc object-oriented database systems, we make it possible not only to answer incomplete queries which are not able to be answered in conventional object-oriented database systems, but also to express the answer-set abstractly as the names of classes, which provides us better understanding of the answer.
