  • Rhetorical relations between two text fragments are essential information and support natural language processing applications such as Question - Answering (QA) system and automatic text summarization to produce an effective outcome. Question - Answering (QA) system facilitates users to retrieve a meaningful response. There is a demand for rhetorical relation based datasets to develop such a system to interpret and respond to user requests. There are a limited number of datasets for developing an Arabic QA system. Thus, there is a lack of an effective QA system in the Arabic language. Recent research works reveal that unsupervised learning can support the QA system to reply to users queries. In this study, researchers intend to develop a rhetorical relation based dataset for implementing unsupervised learning applications. A web crawler is developed to crawl Arabic content from the web. A discourse-annotated corpus is generated using the rhetorical structural theory. A Naïve Bayes based QA system is developed to evaluate the performance of datasets. The outcome shows that the performance of the QA system is improved with proposed dataset and able to answer user queries with an appropriate response. In addition, the results on fine-grained and coarse-grained relations reveal that the dataset is highly reliable.

  • This treatise makes clear not only a structural methodology of 'the conceptual blending theory' using in a linguistics could be applied to the similar process in a hybrid design but also both methods include the same meaning construction in the sense of a mutual educational system. Both methods have something in common that they are fundamentally focused on a metaphorical expression which implies poetic messages to be concentrated on a formal structure. Therefore, the purpose of this treatise is to examine the structural characteristics in the hybrid design in order to analyze the rhetorical expressions(metaphor, allegory) as symbols of communication. One of the those is intertextuality that expresses metaphorically by blending and borrowing codes and another is hypertextual space where various texts twines around each other making brand-new and diverse organizations, as the combined allegory with a number of hidden expression. Ultimately, it is important that this approach could verify whether it deals the illogical present state of a spacial form or structure with a kind of mechanism of a 'conceptual blending theory' or not.

  • 수사구조는 텍스트의 각 구성 성분이 맺고 있는 관계를 의미하며, 필자의 의도는 논리적인 구조를 통해서 독자에게 더 잘 전달될 수 있다. 따라서 독자의 인지적 효과를 극대화할 수 있도록 수사구조를 고려하여 단락과 문장 구조를 구성하는 것이 필요하다. 그럼에도 불구하고 지금까지 수사구조에 기초한 한국어 분류체계를 만들거나 주석 코퍼스를 설계하려는 시도가 없었다. 본 연구에서는 기존 수사구조 이론을 기반으로, 한국어 보도문 형식에 적합한 30개 유형의 분류체계를 정제하고 최소 담화 단위별로 태깅한 코퍼스를 구축하였다. 또한 구축한 코퍼스를 토대로 중심문장을 비롯한 문장 구조의 특징과 분포 비율, 신문기사의 장르적 특성 등을 살펴봄으로써 텍스트에서 응집성의 실현 양상과 구문상의 특징을 확인하였다. 본 연구는 한국어 담화 구문에 적합한 수사구조 분류체계를 설계하고 이를 이용한 주석 코퍼스를 최초로 구축하였다는 점에서 의의를 갖는다.

  • In 1999, the French semiotician Jacques Fontanille published his work on discourse semiotics as an attempt to overcome the limitations of structuralism. Discourse semiotics has expanded the realm of semiotics by taking a phenomenological approach that examines the structure of consciousness. Phenomenology pays special attention to the operation of human consciousness, which, instead of staying put, moves from one place to another-unbeknownst to its agent. This paper examines "Bulls" through a phenomenological approach as the short story depicts the stream of consciousness that unfolds within the inner world of Pau, the young male protagonist. The rhetorical approach to literary analysis works at the level of the speech act and directly relates to speech act theory. In rhetorics, figures and tropes are dominated by speech acts. Whereas conventional rhetorical analysis lacks a kinetic perspective as it revolves around flat semantic inspections, the discourse semiotics approach applied in this paper allows for an indepth multidimensional analysis where the analyses of ${\acute{e}}nonc{\acute{e}}$ and ${\acute{e}}nonciation$ complement each other. Presenting a peasant movement to the reader through the eyes of the young male protagonist Pau, "Bulls" is considered a significant literary feat in the history of Korea's New Literature as the work is highly regarded for its impressive depiction of a communal movement. This paper reinterprets and reevaluates the story under a new light, mainly through a rhetorical approach and a phenomenological approach that hinges on discourse semiotics.

  • This study analyzes location based game focused on the figurative characteristics of mobility. The purpose of this analysis is to extend the understandings of game mobility from technical side toward rhetorical territory. Christian Metz's film theory is appropriate for analysis of the game which is visual and combinational text. According as research findings, structuralize 5-layered spatial maps. And this kind of multi-layering structure generates figurative operations. Adaptive mobility by metaphor, it reflects player's real world movement into the virtual space. Metonymy brings given mobility, it reflects character's movement through all of the virtual maps.

  • The existing interface study has been focused on rhetorical metaphor based on a cognitive viewpoint in traditional objectivism. But the existing study viewpoint about the interface shows logical limitation by the changes in media environment. This study suggests conceptual metaphor based on embodied cognition for an alternative to solve the limitation, and research logical suitability of the existing interface environment. The result of this study is as follow; The first, the embodied cognitive viewpoint provides the interface as a space for holistic recognition communication, and the conceptual metaphor based on embodied cognition provides a well-structured metaphor logic and is a suitable metaphor to explain complicated metaphor structure. The second, the container image schema provides concrete and detailed metaphor structure than previous metaphor when it comes to explaining desktop metaphor by offering subsidiary image schema from 'IN-OUT-BOUNDARY' image schema. The third, path image schema is possible to make a concrete logic and works off the laxity and confusion of logical structure in existing metaphor by offering subsidiary image schema from 'SOURCE-PATH-GOAL' image schema. The conceptual metaphor based on embodied cognition is expected to be a basic theory to explain interfaces for various media environment by thinking of human physical experience as container and path image schema.
