  • In this paper, we describe the answer pattern for definitional question-answering system. The .answer extraction method of a definitional question-answering system is different from the general answer extraction method because it presents the descriptive answer for a definitional question. The definitional answer extraction using the definitional answer pattern can extract the definitional answer correctly without the semantic analysis. The definitional answer pattern is consist of answer pattern, conditional rule and priority to extract the correct definitional answer. We extract the answer pattern from the definitional training corpus and determine the optimum conditional rule using F-measure. Next, we determine the priority of answer patterns using precision and syntactic structure. Our experiments show that our approach results in the precision(0.8207), the recall(0.9268) and the F-measure(0.8705). It means that our approach can be used efficiently for a definitional question-answering system.

  • Objectives : To evaluate the properness and effectiveness of the question categories concerning 'sasang constitutional characteristics of mind', used in Iksan Wonkwang Oriental Medicine. Methods : We statistically analyzed data from those 1335 patients focussing on 'relative discrimination ability' to sasang constructions and 'response ratio'. Patients included in this research are only those who had been well treated in Iksan Wonkwang Oriental Medicine during the Period of three years from 2000 to 2002. The data are obtained through the electronic chart developed by Kim Jong-Yeal, and analyzed using the statistical Package SPSS. Results: In total characteristics of mind, the question category of 'timid' has high discriminating power and effectiveness to Soeum type, more in women than men, and especially with an age of 21 or more; The category of 'hasty-tempered' to Soyang type in women with all ages and men with ages 21-40; The category of 'broad-minded' to Taeum type with ages 41 or more; The category of 'timid and broad-minded' to Soyang type, and especially high to women with ages 41 or more. Question categories concerning response type in anger were estimated to have different response patterns to sasang constructions only for ages 21 or more by $X^2$2 test. The question category of 'bear and last long' has high discriminating power and effectiveness to Soeum type, more in men than women, and increasingly to ages; The category of 'impatient and disarmed quickly' to Soyang type in both women and men, especially with ages 21 or more; The category of 'impatient' to Soyang type women or with ages 21 or more. Other categories have low discriminating power or low effectiveness. Concernig expression type of one's thought, the question category of 'straightly' has high discriminating power and effectiveness to Soyang type, more in wemen than men, and especially to ages 21 or more; The category of 'tender' to Soeum type, in women or with ages 40 or less; The category of 'indirectly' to Taeum type in men or with ages 41 or more; The category of 'straightly and stuborn' to Soyang type with ages 41 or more; The category of 'indirectly and tender' to Soeum with with ages 20 or less; The category of 'not express and tender' to Soeum type with ages 41 or more; Conclusions : Question categories concerning total characteristics of mind, response type in anger and expression type of one's thought, are partially discriminating and effective to specific constitution according to sex and ages, and some categories are more discriminating and effective when they are composited. But generally, the discriminating power of Taeum constitution group and group with ages 20 or less was too low, so it is necessary to develope question categories for those groups.

  • This paper proposes an approach using taxonomic relatedness for answer-type recognition and type coercion in a question-answering system. We introduce a question analysis method for a lexical answer type (LAT) and semantic answer type (SAT) and describe the construction of a taxonomy linking them. We also analyze the effectiveness of type coercion based on the taxonomic relatedness of both ATs. Compared with the rule-based approach of IBM's Watson, our LAT detector, which combines rule-based and machine-learning approaches, achieves an 11.04% recall improvement without a sharp decline in precision. Our SAT classifier with a relatedness-based validation method achieves a precision of 73.55%. For type coercion using the taxonomic relatedness between both ATs and answer candidates, we construct an answer-type taxonomy that has a semantic relationship between the two ATs. In this paper, we introduce how to link heterogeneous lexical knowledge bases. We propose three strategies for type coercion based on the relatedness between the two ATs and answer candidates in this taxonomy. Finally, we demonstrate that this combination of individual type coercion creates a synergistic effect.

  • Objectives : The study explored perceptional gap of dentists and their employees between expectation and satisfaction. Methods : For analysis, the study surveyed 407 employees and 91 dentists on their expectation and satisfaction depending on expectation. Results : When the satisfaction on a question was lower than expectation; the rate of sufficiency was below 100%, it is necessary to improve on the question. Contrarily when the satisfaction on a question was higher than expectation; the rate of sufficiency was upper 100%, it is necessary to continuously support the question. The most of satisfaction of employees on their dentists and their organization were lower than employees's expectation of those. The most of satisfaction of dentists on their own and employees were lower than dentists's expectation of those as similar as employees cases, It means that all of questions need to improve continuously. Conclusions : The issues for prior decision to change these phenomena are 1) improvement of communication each other, 2) recovery of credence each other, and 3) leadership style change from authoritarian to consideration.

  • The performance of a novel medical question-answering engine called CliniCluster and existing search engines, such as CQA-1.0, Google, and Google Scholar, was evaluated using known-item searching. Known-item searching is a document that has been critically appraised to be highly relevant to a therapy question. Results show that, using CliniCluster, known-items were retrieved on average at rank 2 ($MRR@10{\approx}0.50$), and most of the known-items could be identified from the top-10 document lists. In response to ill-defined questions, the known-items were ranked lower by CliniCluster and CQA-1.0, whereas for Google and Google Scholar, significant difference in ranking was not found between well- and ill-defined questions. Less than 40% of the known-items could be identified from the top-10 documents retrieved by CQA-1.0, Google, and Google Scholar. An analysis of the top-ranked documents by strength of evidence revealed that CliniCluster outperformed other search engines by providing a higher number of recent publications with the highest study design. In conclusion, the overall results support the use of CliniCluster in answering therapy questions by ranking highly relevant documents in the top positions of the search results.
