  • The purpose of this study is to see and compare the contemporary Korean-Thai female poems from a feminine standpoint to newly clarify the textuality of their poems. The textuality defined in this manuscript is the text of Korean-Thai contemporary female poems. To newly clarify the textuality of their poems are to go against the existing discussion method and to newly read out the text as re-vision method. This discussion is to analyse deeply how the central exis composing a text which is the identity of woman in a body, appearance of uttrance, or action of abjection is exposed in gender space and to identify the poem's textuality. In other words, through in-depth analysis of the text of poems, which are very complicated as a skein of yarn, place a high value of Korean-Thai female poems. Transcending time, nations and races, if the text of female poem would not free from a biased male-dominated thinking or make a mystery of female poem textuality without critics or tend to be stereotype the text of poem as pathos of female, it would not get out from man-centered reading. To escape from the state of sexual discrimination, the new reading method was seriously analysed and found out that the female text poems not only implicate sexual discrimination but also link to expansive cultural and social structure. And for that reason, this study raise a question to male-dominant sexual discriminated norm. It is very significant that through this elaborate and in-depth text poem analysis, a creation process of female poem is traced. Eventually, the comparative study on Korean-Thai female poems is meaningful and worthy in regard to the contribution to promotion of cultural exchange between korea-Thai two nations and furthermore extend to East Asia to make a basement for the vitalization of Asia comparative literature.

  • The students' feedback is important to measure and improve teaching performance. Many teacher performance evaluation systems are based on responses to closed question, but the free text answers can contain useful information which had to be explored. In this paper we present a lexicon-based sentiment analysis to explore students' text feedback. The data was collected from a system for the evaluation of teachers by students developed and used in our university. The students comments are in Romanian language so we built a Romanian sentiment word lexicon. We used this to categorize the feeback text as positive, negative or neutral. In addition, we added a new polarity - indifferent - in order to categorize blank and "I don't answer" responses.

  • This paper explores a method of text watermarking for agglutinative languages and develops a syntactic tree-based syntactic constituent movement scheme. Agglutinative languages provide a good ground for the syntactic tree-based natural language watermarking because syntactic constituent order is relatively free. Our proposed natural language watermarking method consists of seven procedures. First, we construct a syntactic dependency tree of unmarked text. Next, we perform clausal segmentation from the syntactic tree. Third, we choose target syntactic constituents, which will move within its clause. Fourth, we determine the movement direction of the target constituents. Then, we embed a watermark bit for each target constituent. Sixth, if the watermark bit does not coincide with the direction of the target constituent movement, we displace the target constituent in the syntactic tree. Finally, from the modified syntactic tree, we obtain a marked text. From the experimental results, we show that the coverage of our method is 91.53%, and the rate of unnatural sentences of marked text is 23.16%, which is better than that of previous systems. Experimental results also show that the marked text keeps the same style, and it has the same information without semantic distortion.
