  • In this paper, we describe a deep analysis of question for question answering system. It is difficult to offer the correct answer because general question answering systems do not analyze the semantic of user's natural language question. We analyze user's question semantically and extract semantic features using the semantic feature extraction grammar and characteristics of natural language question. They are represented as semantic features and grammatical morphemes that consider semantic and syntactic structure of user's questions. We evaluated our approach using 100 questions whose answer type is a person in the web. We showed that a deep analysis of questions which are comparatively short but enough to mean can analysis the user's intention and extract semantic features.

  • A user should pick up relevant answers by himself from various search results when using user participation question answering community like Knowledge-iN. If refined answers are automatically provided, usability of question answering community must be improved. This paper divides questions in Q&A documents into 4 types(word, list, graph and text), then proposes summarizing methods for each question type using document statistics. Summarized answers for word, list and text type are obtained by question clustering and calculating scores for words using frequency, proximity and confidence of answers. Answers for graph type is shown by extracting user opinion from answers.

  • It is not easy to develop the system as the subjective-type evaluation has the difficulty in natural language processing. This thesis designs and implements the automatic evaluation system with natural language processing technique. To solve the degradation of general evaluation system, we define the question type and improve the performance of evaluation through the adaptive process for each question type. To evaluate the system, we analyze the correlation between human evaluation and term-based evaluation, and between human evaluation and this system evaluation. We got the better result than term-based evaluation. It needs to expand the question type and improve the adaptive processing technique for each type.

  • Mathematical process is an issue in current mathematics education. In this paper discuss how to assess the mathematical process using essay type questions. For this we first suggest the concept of Mathematical Process Oriented Question which is an essay type question and possible to assess mathematical processes, that is, the mathematical communication, reasoning, and problem solving as well as mathematics knowledge. And we develop a framework for developing the mathematical process oriented question and rubric, examples of assessment standards and those questions containing rubric for assessing mathematical processes. The results of this paper can serve as basic data and examples for follow up research about mathematical process assessment.

  • Question-Answering (QA) system has to analyze user's intention correctly to respond correct answer for user's question., This paper proposes a focus-word-based question analysis approach for Korean QA system to analyze user's intention correctly. focus-word is a clue-word which selects question type. The question type is determined to one in 75 subcategories using semantics of focus-words. the proposed system accomplished 97.18% accuracy for the main category and 95.31% accuracy for the subcategory in the question classification.

  • The purpose of this study was to investigate the relationship between conversational function and question type in mothers' utterances and their infant's language development. The subjects were 20 infants from 1;07 to 1;11 years of age in Yanji, China. Each child's spontaneous natural speech during interaction with his/her mother was videotaped for about 30 minutes. The children and their mother's spontaneous utterances were transcribed and coded for the number of type and token of word, grammatical morpheme conversational function and type of question in mother's language input to her child. The result showed that mothers used questions as the most frequent conversational function with their infants. The number of questions in conversational function in mothers' utterances positively correlated with the type of word, type of morpheme and grammatical morpheme in infants' utterance. However, there was no correlation between mothers' language input and infant early language development.

  • The question style In high school enoronmental science textbook was examined in terms of the placement, frequency, and type of question, and then analyzed the kind of scientific Inquiry process elicited by the question In the topic of textbook using the Tektbook guestioning Strategy Assessment Instrument (TQSAI). The average number of question per topic was only 0.6. The number of all Question In the high school enororunental science textbook was very little : the number of non-experiential Question was 8 and that of experiential one was 3. The total number of sentence was 1,236 and the ratio of the number of Question to that of sentence was 0.9% . The frequency of non-experlential question was higher than that of experiential one. In action part of the textbook, there were more kinds of Question styles than In the matin part.

  • This study was conducted to investigate the relationships between the patterns of elementary school teachers' explanations and the patterns of students' questions types on scientific phenomena. for the purposes of this study, we collected questions related to scientific phenomena from 255 $3rd{\sim}6th$ students in 2 elementary schools. Classifying the students' questions collected, 20 representative questions for each type were selected. Data regarding teachers' scientific explanation from 62 teachers of 3 elementary schools were also collected. The results of the analysis of the questions for each science field show that the students in the 3rd, 4th, and 5th grades have the most questions regarding biology, and those in the 6th grade have more questions regarding earth science. Regarding question types, object exploration questions and explican exploration questions formed the majority. Moreover, the higher the students' grades, a decrease in the number of conjectural questions and an increase in the number of causal questions were observed. As a result of the analysis of the teachers' explanation, the following explanation types could be discerned; conjecture, hypothesis, prediction, teleological explanation, information given to feed exploration questions, as well as verification and information supply fer verification purposes. There were 4 kinds of relationships between question types and explanation types. One was the explanation fitting to each question type, a second was the explanation with additional content than the question required, a third was where the explanation was inappropriate to the question, and a forth was where the teacher responded that they "don't know." This study, investigating the relationships between questioning as a scientific inquiry process and explanation, will help to promote discussion regarding science classes in elementary school.
