In this paper, we describe a design and implementation of the Wireless Markup Language(WML) compiler to deploy wireless Internet services effectively. The WML compiler translates textual WML decks into binary ones in order to reduce the traffic on wireless links that have relatively low bandwidth to wireline links and mitigate the processing overhead of WML decks on, wireless terminals that have relatively low processing power to fixed workstations. In addition, it takes over the overhead of eXtensible Markup Language(XML) well-formedness and validation processes. The WML compiler consists of the lexical analyzer and parser modules. The granunar for the WML parser module is LALR(1) context-free grammar that is designed based on XML 1.0 and WML 1.2 DTD(Document Type Definition) with the consideration of the Wireless Application Protocol Binary XML grammar. The grammar description is converted into a C program to parse that grammar by using parser generator. Even though the tags in WML will be extended or WML DTD will be upgraded, this approach has the advantage of flexibility because the program is generated by modifying just the changed parts. We have verified the functionality of the WML compiler by using a WML decompiler in the public domain and by using the Nokia WAP Toolkit as a WAP client. To measurethe compressibility gain of the WML compiler, we have tested a large number of textual WML decks and obtained a maximum 85 %. As the effect of compression is reduced when the portion of general textual strings increases relative to one of the tags and attributes in a WML deck, an extended encoding method might be needed for specific applications such as compiling of the WML decks to which the Hyper Text Markup Language document is translated dynamically.

The main purpose of this paper is to take a look at a controversial approach to critical discourse analysis for the suggestion of a well-balanced perspective on such a biased presupposition and methodology. Currently linguists, language teachers and even social scientists have shown their strong interests in critical language awareness and its ideological involvements in order to encourage the general public to realize the social function of language in all modes of communication. It seems, however, to me to be increasingly clear that critical language study calls for a careful attempt based on an appropriate combination of textual facts and contextual factors in the interpretation of discourses. From this point, of view, this paper suggests some pedagogic / analytical guidelines for a study on language and its social connotations as a result of examining the cogency of two contrasting argumentations in relation to critical discourse analysis.

This study explores the characteristics and roles of non-textual elements in secondary mathematics textbooks in the United States and South Korea, using a conceptual framework that I have developed: variety, contextuality, and connectivity. Analyzing five U.S. standards-based textbooks and 13 Korean textbooks, this study shows that although non-textual elements in mathematics textbooks are free of literal language, they exhibit different emphases and reflect assumptions about what is important in learning mathematics and how it can be taught and learned in a particular societal context (Mishra, 1999; Zazkis & Gadowsky, 2001). While there are similar patterns in the use of different types of non-textual elements in textbooks from both countries, different opportunities are provided for students to learn mathematics between the two countries.

Identifying the speakers of individual utterances mentioned in textual stories is an important step towards developing applications that involve the use of unique characteristics of speakers in stories, such as robot storytelling and story-to-scene generation. Despite the usefulness, it is a challenging task because not only human entities but also animals and even inanimate objects can become speakers especially in fairytales so that the number of candidates is much more than that in other types of text. In addition, since the action of speaking is not always mentioned explicitly, it is necessary to infer the speaker from the implicitly mentioned speaking behaviors such as appearances or emotional expressions. In this paper, we investigate a method to exploit linguistic clues to identify the speakers of utterances from textual fairytale stories in Korean, especially in order to handle such challenging issues. Compared with the previous work, the present work takes into account additional linguistic features such as vocative roles and pairs of conversation participants, and proposes the use of discourse-level turn-taking behaviors between speakers to further reduce the number of possible candidate speakers. We describe a simple rule-based method to choose a speaker from candidates based on such linguistic features and turn-taking behaviors.

With the rapid development of e-commerce, many customers can now express their opinion on various kinds of product at discussion groups, merchant sites, social networks, etc. Discerning a consensus opinion about a product sold online is difficult due to more and more reviews become available on the internet. Opinion Mining, also known as Sentiment analysis, is the task of automatically detecting and understanding the sentimental expressions about a product from customer textual reviews. Recently, researchers have proposed various approaches for evaluation in sentiment mining by applying several techniques for document, sentence and aspect level. Aspect-based sentiment analysis is getting widely interesting of researchers; however, more complex algorithms are needed to address this issue precisely with larger corpora. This paper introduces an approach of knowledge representation for the task of analyzing product aspect rating. We focus on how to form the nature of sentiment representation from textual opinion by utilizing the representation learning methods which include word embedding and compositional vector models. Our experiment is performed on a dataset of reviews from electronic domain and the obtained result show that the proposed system achieved outstanding methods in previous studies.

In Written on the Body, by creating the narrator's ungendered and unsexed identity, Winterson makes her text open to the reader's assumption of the narrator's sexual and gender identity. Thus, this novel has been read, on the one hand, as a lesbian text by those who assume that the narrator is a female and, on the other hand, as a suspicious text colluding with patriarchal and heterosexual values by those who define the narrator as a male. Those readings of the narrator as one of either sex/gender, however, demonstrate how (academic as well as general) readers have been accustomed to the gender-based reading habits in which textual meanings are dichotomously arranged along the lines of sex and gender of characters. Challenging those dualistic "gendered" readings, this paper reads Winterson's Written on the Body as a queer text which interrogates, troubles, and subverts the heterosexual concepts of narrative, desire, and body without reducing the narrator's identity to the essentialist sex and gender system. More specifically, this paper examines how the narrator's 'un-/over-' determined sexual and gender identity queers the narrative structure of author-character-reader; how the narrator's queer (fluid) desire is passing and traveling across categorical contours of (homo-/hetero-) sexual desires; how Winterson challenges the concept of a coherent body and queers the concept of body as a hermeneutic text with myriad textual grids which are not coherently mapped by power but randomly inscribed by nomadic desires.

For Romantic women writers the paratext itself is essentially a masculine literary space affiliated with established writing practices; however, this paper suggests that Charlotte Turner Smith's mode of discourse in her use of notes and their relation to the text proper are never fixed in her contemplative blank-verse long poem, Beachy Head (1807). Even though the display of learning in the paratext partly supports the woman writer's claim to authority, this paper argues that Smith's endnotes also indicate her way of challenging the double bind for women writers, summoning masculine authority on the margins of her book while simultaneously interrogating essentialist thinking and instructions about one's identity in a culture and on the printed page. The poem shows how the fringes of the book can be effectively transformed from a masculine site of authority to an increasingly feminized site of interchange as Smith writes with an awareness of patriarchal, imperial abuses of power in that area of the book. There is a persistent transgression of cultural/textual boundaries occurring in Beachy Head, which explores the very scene and languages of imperial encounter. Accordingly, if Wordsworth's theory of composition suggests a subjective and abstract poetic experience-an experience without mediation-in which its medium's purpose seems to be to disappear from the reader's consciousness, an examination of the alternative discourse of self-exposure in Smith's poem reveals the essentially fluid nature of media-consciousness in the Romantic era, which remains little acknowledged in received accounts of Romantic literary culture.

Special-purpose microcontrollers PLCs have been widely used in the area of industrial automation. For the research of analysis and verification for PLC programs, first of all we have to specify formal sematics of PLC programming languages. This paper defines formally the operational semantics of LD language. After we transform the graphical language LD into its textual representation Symbolic LD, we give semantics of Symbolic LD since LD language is a graphical language. This paper defines the natural sematics of Symbolic LD and formalizes it in Coq proof assistant.

Chatbots were an important research subject in the past. A chatbot is a computer program or an artificial intelligence program that participates in a conversation via auditory or textual methods. As the research on chatbots progressed, some important issues regarding them changed over time. Therefore, it is necessary to review the technology with a focus on recent advancements and core research technologies. In this paper, we introduce five different chatbot technologies: natural language processing, pattern matching, semantic web, data mining, and context-aware computer. We also introduce the latest technology for the chatbot researchers to recognize the present situation and channelize it in the right direction.
