This paper suggests a method to refine a massive collective intelligence data, and visualize with multilevel sentiment network, in order to understand information in an intuitive and semantic way. For this study, we first calculated a frequency of sentiment words from each movie review. Second, we designed a Heatmap visualization to effectively discover the main emotions on each online movie review. Third, we formed a Sentiment-Movie Network combining the MDS Map and Social Network in order to fix the movie network topology, while creating a network graph to enable the clustering of similar nodes. Finally, we evaluated our progress to verify if it is actually helpful to improve user cognition for multilevel analysis experience compared to the existing network system, thus concluded that our method provides improved user experience in terms of cognition, being appropriate as an alternative method for semantic understanding.

This paper provides suggestions for analyzing Cultural Objects Name Authority(CONA) developed by the Getty Trust and applying CONA to Functional Requirements for Subject Authority Data(FRSAD). CONA is linked with the other Getty controlled vocabularies such as AAT, ULAN, and TGN, and can be linked with the library controlled vocabularies, such as LCSH. However, CONA has differences with library models since CONA is based on the art museum or art gallery. Therefore, we need to consider it when we link CONA to library standard models. The results discussed in this study have implications for analyzing CONA which provides access for cultural objects and applying it to the FRSAD, the subject authority model in library fields.

For effective battlefield situation awareness and command resolution, information exchange without seams between systems is essential. However, since each system was developed independently for its own purposes, it is necessary to ensure interoperability between systems in order to effectively exchange information. In the case of our military, semantic interoperability is guaranteed by utilizing the common message format for data exchange. However, simply standardizing the data exchange format cannot sufficiently guarantee interoperability between systems. Currently, the U.S. and NATO are developing and utilizing information exchange models to achieve semantic interoperability further than guaranteeing a data exchange format. The information exchange models are the common vocabulary or reference model,which are used to ensure the exchange of information between systems at the content-meaning level. The information exchange models developed and utilized in the United States initially focused on exchanging information directly related to the battlefield situation, but it has developed into the universal form that can be used by whole government departments and related organizations. On the other hand, NATO focused on strictly expressing the concepts necessary to carry out joint military operations among the countries, and the scope of the models was also limited to the concepts related to command and control. In this paper, the background, purpose, and characteristics of the information exchange models developed and used in the United States and NATO were identified, and comparative analysis was performed. Through this, we intend to present implications when developing a Korean information exchange model in the future.

This paper focuses on the DSP implementation of an HMM-based speech recognizer that can handle several hundred words of vocabulary size as well as speaker independency. First, we develop an HMM-based speech recognition system on the PC that operates on the frame basis with parallel processing of feature extraction and Viterbi decoding to make the processing delay as small as possible. Many techniques such as linear discriminant analysis, state-based Gaussian selection, and phonetic tied mixture model are employed for reduction of computational burden and memory size. The system is then properly optimized and compiled on the TMS320C6711 DSP for real-time operation. The implemented system uses 486kbytes of memory for data and acoustic models, and 24.5 kbytes for program code. Maximum required time of 29.2 ms for processing a frame of 32 ms of speech validates real-time operation of the implemented system.

The purpose of this study was to examine the effects of advertisement-making activities on young children's language ability and creativity. The subjects of this study were 47 five-years-old children from child care center located in Gwangju City. The collected data were analyzed by idependent t-test using SPSS Program.The results of this study were as follows; First, experimental group which conducted the advertisement-making activities showed significantly higher improvement in sub-factors of language abilities, common sense, comprehension, vocabulary ability, commonness than comparative group. Second, experimental group which conducted the advertisement-making activities showed significantly higher improvement in sub-factors of creativity, fluency, uniqueness, elaboration than comparative group. It means that the advertisement-making activities improve young children's language ability and creativity.

This study investigated differences in toddlers' language development depending on their teachers' types of interaction during reading of picture books. A pilot study identified teachers' types of interaction as instructional, non-immediate, and passive. Fifteen teachers recruited from 10 child-care centers located in Seoul and their 90 2-year-old toddlers participated in this study. Teachers read two picture books to a small group of toddlers each week for eight weeks. Data on the toddlers' receptive and expressive language, vocabulary, reading behavior, and book handling were collected and compared by their teachers' interaction type before and after teachers' 8-week reading of picture books. Results showed that teachers using the non-immediate interaction type had the most positive effects on toddlers' language development.

In this paper, we proposed a dictionary extension and a ternary decomposition technique to improve the effectiveness of Khmer word segmentation. Most word segmentation approaches depend on a dictionary. However, the dictionary being used is not fully reliable and cannot cover all the words of the Khmer language. This causes an issue of unknown words or out-of-vocabulary words. Our approach is to extend the original dictionary to be more reliable with new words. In addition, we use ternary decomposition for the segmentation process. In this research, we also introduced the invisible space of the Khmer Unicode (char\u200B) in order to segment our training corpus. With our segmentation algorithm, based on ternary decomposition and invisible space, we can extract new words from our training text and then input the new words into the dictionary. We used an extended wordlist and a segmentation algorithm regardless of the invisible space to test an unannotated text. Our results remarkably outperformed other approaches. We have achieved 88.8%, 91.8% and 90.6% rates of precision, recall and F-measurement.

For the development of a short form of the Korean Wechsler Preschool and Primary Scale of Intelligence (K-WPPSI), 360 preschool and primary school children were tested with 4 subtests: Object Assembly, Arithmetic, Block Design, and Comprehension. Transformed scores were derived according to K-WPPSI norms. Interscorer reliability coefficients measured by two independent scorers with the data of 16 children were satisfactory: Comprehension, .92; Arithmetic, .94; Block Design, .97; Object Assembly, .97 Cronbach alpha reliability coefficient for the 4 subtests were very similar to those for the original K-WPPSI, ranging between .71 and .92. Factor analyses revealed 2 factors corresponding to Wechsler's 2 factor theory of intelligence. Discriminant validity was obtained with a Picture-Vocabulary test. Boys performed slightly better than girls on all subtests except for Comprehension. Boys significantly out-performed girls in Arithmetic.

This study investigated the relationship between young children's comprehension and story making(narrative) by age and gender. Subjects were 109 3-, 4-, and 5-year-olds at two child care centers in K Province. Data were analyzed by two-way ANOVA and simple regression analysis. Results showed differences in comprehension between 3-, 4- and 5-year old children and differences in story making ability between 3- and 5-year-old children. Children's comprehension and story making had positive relationships. Specifically, there were significant relationships with children's comprehension and story construct concept, sentence structure level, language(vocabulary and sentence structure). In sum, the results of this study reveal that young children's comprehension ability is partially related to story making ability by age.
