A selection methodology of liquid levelmeters, especially, level sensors in non-nuclear category, to be installed in nuclear energy facilities is developed using linguistic fuzzy approaches such as fully-linguistic and semi-linguistic methods. Depending on defuzzification techniques, the linguistic fuzzy methodology leads to either linguistic (exactly, fully-linguistic) or cardinal (i.e., semi-linguistic) evaluation. For the linguistic method, for each alternative, fuzzy preference index is converted to linguistic utility value by means of a similarity measure determining the degree of similarity between fuzzy index and linguistic ratings. For the cardinal method, the index is translated to cardinal overall utility value. According to these values, alternatives of interest are linguistically or numerically evaluated and a suitable alternative can be selected. Under given selection criteria, the suitable selections out of some liquid levelmeters for nuclear facilities are dealt with using the linguistic fuzzy methodology proposed. Then, linguistic fuzzy evaluation results are compared with qualitative result available in the literature. It is found that as to a suitable option the linguistic fuzzy selection is in agreement with the qualitative selection. Additionally, the comparative study shows that the fully-linguistic method using adequate scale system facilitates linguistic interpretation regarding evaluation results.

In this paper, we notice the fact that a human learning process is characterized by a process under a natural language environment, and discuss an approach of learning based on indirect linguistic instructions. An instruction is interpreted through some meaning elements and each trend. Fuzzy evaluation rule are constructed for the searched meaning elements of the given instruction, and the performance of a system to be learned is improved by the evaluation rules. In this paper, we propose a framework of learning based on indirect linguistic instruction based learning using fuzzy theory: FULLINS(FUzzy-Learning based on Linguistic IN-Struction). The validity of FULLINS is shown by applying it to helicopter flight control.

The meaning of the study is in the following points. The first is to find the linguistic development of children through IQ test. The second is to find the family fostering factor for the linguistic development. For these meaning this study will have the following aims. 1) To judge the similarly agreement between the children lexical ability with the teachers evaluation to the children. 2) To compare the gender differences of lexical abilities between the urban with the rural. 3) To find the family fostering factors for the children linguistic development. The collection data has been from April 13, 1999 to April 27. The subjects for this study were two grade of elementary school, which is located in "K" city and "O"rural a chosen students(273), teachers(5), parents(176). The instruments used for this study were IQ test by Korea Behavioral Science institute and family fostering environment 25 items. Teachers linguistic evaluation. The data analysis was done using Pearson's Correlation Coefficient, t-test, ANOVA using SPSS/pc program. This study found following results. 1) The similarly agreement degree between children lexical abilities with teachers comprehending evaluation maler r= .745, female r=0.809 The similarly agreement degree between children lexical abilities with teachers expressing evaluation, male r= .657, female r= .797(P<.01) 2) In comparing of the gender difference of urban, the femail is a little high than male(t= .5065), but the especial point is more large difference in male than in female. In comparing of the gender difference of rural, the female is especial high than the male(t=-4.411). (P<.01) 3) The higher factor of influencing the linguistic development is the breast-feeding(r=-.3279) in all the gender(P<.01), So that the brast-feeding better than cow's milk, mother better than the other family members in feeding, 6~8months better than one or two years in feeding term.

An induced hesitant linguistic aggregation operator is investigated in the paper, in which, hesitant fuzzy linguistic evaluation values are associated with probabilistic information. To deal with these hesitant fuzzy linguistic information, an induced hesitant fuzzy linguistic probabilistic ordered weighted averaging (IHFLPOWA) operator is proposed, monotonicity, boundary and idempotency of IHFLPOWA are proved. Then andness, orness and the entropy of dispersion of IHFLPOWA are analyzed, which are used to characterize the weighting vector of the operator, these properties show that IHFLPOWA is extensions of the induced linguistic ordered weighted averaging operator and linguistic probabilistic aggregation operator. In this paper, IHFLPOWA is utilized to gather linguistic information and create fuzzy ontologies, and a movie fuzzy ontology as an illustrative case study is used to show the elaboration of the proposed method and comparison with the existing linguistic aggregation operators, it seems that the IHFLPOWA operator is an useful and alternative operator for dealing with hesitant fuzzy linguistic information with probabilistic information.

This study is about Chinese tone evaluation system for Korean learners using speech technology, Chinese prounciaion system consists of initials, finals and tones. Initials/finals are in segmental level and tones are in suprasegmental level. So different method could be used assessing Korean users' Chinese. Differ from segmental level recognition method, we chose pattern matching method in evaluating Chinese tones. Firstly we defined speakers' own speech range and produced standard tonal pattern according to speakers' own range. And then we compared input patterns of users with referring patterns.

본 논문에서는 시소러스에 근거한 새로운 퍼지 정보검색 기법을 제안한다. 제안된 방법에서 시소러스는 내부 용어들 간의 관련도를 정성적인 언어 갑으로 갖는 퍼지 언어 매트릭스로 표현되며 용어들간의 관계는 동의, 계층, 그릭 연관이 세 가지 관계가 제공된다 싯러스 내부 용어들 간이 무시된 관련도가 퍼기 이론에 근거한 퍼지이론에 근거한 퍼지 언어 매트릭스의 전이 폐쇄 알고리즘에 의해 추론된다 또한 제안돈 방법은 사용자의 질의, 그리고 문서와 같은 정보 항목의 표현에도 인간이 주관적이고 부정확한 측도를 그대로 반영하는 정성적인 언어 값을 허용한다. 따라서 논문 [1-3]에서 제안된 방법보다 좀 더 유용하다. 또한 질의 평가시 퍼지 언어 매트릭스와 AON(Associated Ordinary Number)값을 이용하기 때문에 논문 [1-3]에서 사용되는 방법보다 시간적으로 효츌적이다. 결과적으로 사용자가 좀 더 유용하고 지능적인 방법으로 질의를 처리할 수있도록 한다

기계번역 품질 평가는 중대한 문제이다. 기계번역의 품질이 사용자 요구와 거리가 상당히 있는 현재의 상황에서 기계번역 시스템의 객관적 평가는 기계번역 소프트웨어 사용자와 판매자 간의 신뢰를 구축하고 개발자들 간에 생산적인 경쟁관계를 조성하게 하여 결과적으로 기계번역 품질의 고급화를 지속적으로 유도하는 역할을 할 것이다. 이를 위해서는 특히 언어학적 측면과 자료처리 측면에서 개선이 계속되고 있는지를 확인할 수 있도록 기계번역 시스템의 품질을 평가할 수 있는 연구가 있어야 한다. 본 논문에서는 이런 정들을 고려해 넣은 영한 기계번역의 언어학적 평가 방법을 제시하고 이를 몇 개의 상용 기계번역 시스템을 대상으로 실험하여 실험결과를 보고한다. 이 방법은 기본적으로 언어현상과 학습수준으로 분류된 3.373 영어 문장으로 구성된 평가자료에 기반하고 있다.

The purpose of this study is to propose a method to evaluate task complexity using CIFs(Complexity Influencing Factors). We developed a method that CIFs can be used in the evaluation of task complexity using fuzzy linguistic approach. That is, a fuzzy linguistic multi-criteria method to assess task complexity in a specific task situation was proposed. The CIFs luting was assessed in linguistic terms, which are described by fuzzy numbers with triangular and trapezoidal membership function. A fuzzy weighted average algorithm, based on the extension principle, was employed to aggregate these fuzzy numbers. Finally, the method was validated by experimental approach. In the result, it was validated that TCIM(Tink Complexity Index Method) is an efficient method to evaluate task complexity because the correlation coefficient between task performance time and TCI(Task Complexity Index) was 0.699.
