  • This paper concerns a new method called Fuzzy Supervised Method for error matrix, the method has developed based on Adoptive Neuro- Fuzzy Inference Systems(ANFIS). For the performance point of view initially the new method tested with trial data and then this paper applies the proposed method with real world problems. So that this paper generated 1000 random error matrices in programming language [R] and then it tests the new proposed method for the error matrices. The results of Fuzzy Supervised Method given in terms of Kappa Index and Congalton Accuracy Indexes, and performance of Fuzzy Supervised Method has evaluated by using Pearson's test.

  • This paper investigated the effect of audio and visual cues on Korean and Japanese EFL learners' perception of the lateral/retroflex contrast in English. In a perception experiment, the two English consonants /l/ and /r/ were embedded in initial and medial position in nonsense words in the context of the vowels /i, a, u/. Singletons and clusters were included in the speech material. Audio and video recordings were made using a total of 108 items. The items were presented to Korean and Japanese learners of English in three conditions: audio-alone (A), visual-alone (V) and audio-visual presentation (AV). The results showed that there was no evidence of AV benefit for the perception of the /l/-/r/ contrast for either Korean or Japanese learners of English. Korean listeners showed much better identification rates of the /l/-/r/ contrast than Japanese listeners when presented in audio or audio-visual conditions.

  • The search for relevant and actionable information is a key to achieving clinical and research goals in biomedicine. Biomedical information exists in different forms: as text and illustrations in journal articles and other documents, in images stored in databases, and as patients' cases in electronic health records. This paper presents ways to move beyond conventional text-based searching of these resources, by combining text and visual features in search queries and document representation. A combination of techniques and tools from the fields of natural language processing, information retrieval, and content-based image retrieval allows the development of building blocks for advanced information services. Such services enable searching by textual as well as visual queries, and retrieving documents enriched by relevant images, charts, and other illustrations from the journal literature, patient records and image databases.

  • 본 논문에서는 효율적인 전투체계 소프트웨어 개발방안으로 UML(Unified Modeling Language)을 이용한 모델기반개발방법을 제시한다. UML은 소프트웨어 시스템을 모델링하기 위한 언어로 OMG(Object Management Group)에서 관리되고 있는 통합모델링언어이다. 본 논문에서 제시한 UML(Unified Modeling Language)을 이용하여 소프트웨어를 개발 할 경우, 표준화된 모델 언어를 사용하기 때문에 개발자들의 원활한 의사소통이 가능하여 시스템의 심각한 오류를 줄일 수 있다. 또한, 가독성이 높은 객체 모델들을 사용하기 때문에 추후 요구사항에 대한 소프트웨어 유지/보수에 용이하다는 장점을 가진다.

  • For the purpose of technology planning and R&D strategy, this research developed a methodology for deriving technical information based on stakeholder requirements using natural language processing technology. The requirements are decomposed into semantic information based on grammar rules, and then the requirement information based technology information can be derived by linking with the three technical information extracted from the patent.

  • 본 논문은 한국어를 대상으로 하는 자연언어 처리 시스템을 개발하는데 있어서 기초가 되는 지식베이스의 구축에 대하여 논한다. 한국어의 일반문에서 단문을 분리해 내기 위하여 형태소 해석의 결과로부터 도출한 구 단위를 한-일 기계번역 시스템의 구문, 의미 해석기(VCPN) 을 적용하여 절단위로 결합한다. 그리고 이들 단위절에 대하여 대명사의 조응관계, 생략에의 재생을 위한 추론, 부정어, 시제일치 등을 처리하여 논리적 지식베이스를 구성하는 방법을 제안한다. 본 논문은 입력문장에 제한을 두지 않고 단문으로부터 장문에 이르기까지 광범위한 일반문을 대상으로 하여 Horn Clause 이론을 확장한다.

  • Taiwanese abounds with verbal complexes. Among them, phasal complexes, resultative complexes, and directional complexes are alike in that their second component denotes some sort of result. Moreover, they behave similarly in that they can occur in V-ho-Y, V-e/be-Y, and V-bo-V forms. Despite the similarities, they still differ from one another in several aspects, such as whether objects are allowed inside or after the verbal complex, whether infixing changes their basic meaning, etc. This paper examines their individual properties carefully and proposes that these three types of complexes are all different from one another in their formation and thus the difference in their syntactic behavior. Directional complexes are syntactic phrases, resultative complexes are compounds derived in syntax, and while some phasal complexes are also syntactically derived compounds, others are compounds formed in the lexicon. This paper aims to argue that words (or compounds in this case) can be formed in syntax as well as in the lexicon.

  • This study is to examine the relationship of HOME and personality with Preschool children's school readiness. The subjects were 138 children(4 to 6 year-old) and their mothers in Seoul, Gyunggi-do, and Chungnam. The instruments for this study were Cooperative Preschool Inventory(CPI), The Home Observation for Measurement of the Environment(HOME), and Children's Personality Test. The data were analyfed by Pearson's r, stepwise regression, ANOVA, Scheffe test for the post hoc test, and Cronbach a for the reliability in SPSS PC program. The major findings with the preschool children's school readiness were as follows. 1) That was significant correlations with HOME(language environment and encouragement of independence) and personality(sociability and familiarity). 2) That was explained significantly by sociability, encouragement of independence, language environment, and stimuli for development. 3) That was no sex-difference and was an increase by age. 4) There were significant differences in preschool children's school readiness, HOME, and personality by familial demographic variables.

  • A hot-issued research topic in the workflow intelligence arena is the emerging topic of "workflow-supported organizational social networks." These specialized social networks have been proposed to primarily represent the process-driven work-sharing and work-collaborating relationships among the workflow-performers fulfilling a series of workflow-related operations in a workflow-supported organization. We can discover those organizational social networks, and visualize its analysis results as organizational knowledge. In this paper, we are particularly interested in how to visualize the degrees of closeness centralities among workflow-performers by proposing a graphical representation schema based on the Graph Markup Language, which is named to ccWSSN-GraphML. Additionally, we expatiate on the functional expansion of the closeness centralization formulas so as for the visualization framework to handle a group of workflow procedures (or a workflow package) with organizational workflow-performers.
