  • The Question Similarity Measurement of Chinese Crop Diseases and Insect Pests (QSM-CCD&IP) aims to judge the user's tendency to ask questions regarding input problems. The measurement is the basis of the Agricultural Knowledge Question and Answering (Q & A) system, information retrieval, and other tasks. However, the corpus and measurement methods available in this field have some deficiencies. In addition, error propagation may occur when the word boundary features and local context information are ignored when the general method embeds sentences. Hence, these factors make the task challenging. To solve the above problems and tackle the Question Similarity Measurement task in this work, a corpus on Chinese crop diseases and insect pests(CCDIP), which contains 13 categories, was established. Then, taking the CCDIP as the research object, this study proposes a Chinese agricultural text similarity matching model, namely, the AgrCQS. This model is based on mixed information extraction. Specifically, the hybrid embedding layer can enrich character information and improve the recognition ability of the model on the word boundary. The multi-scale local information can be extracted by multi-core convolutional neural network based on multi-weight (MM-CNN). The self-attention mechanism can enhance the fusion ability of the model on global information. In this research, the performance of the AgrCQS on the CCDIP is verified, and three benchmark datasets, namely, AFQMC, LCQMC, and BQ, are used. The accuracy rates are 93.92%, 74.42%, 86.35%, and 83.05%, respectively, which are higher than that of baseline systems without using any external knowledge. Additionally, the proposed method module can be extracted separately and applied to other models, thus providing reference for related research.

  • This study discusses "mechanisms" in a research facility, specifically focusing on the question of how we can understand what happens in the physical environment and the communication between researchers. This study attempts to address this question by examining two physical settings, before and after the move of one research-educational facility, the Institute of Paper Science and Technology. The objective of the study is to suggest conceptual models to comprehend the relationships between spatial layouts and communication. The study examines the underlying mechanism of how the levels of communication meet the layers of spatial structure. The paper has four parts. First, the preceding studies will be reviewed evoking some issues of communication and physical setting in research facilities. Second a conceptual typology in office plan will be developed providing a theoretical framework to review the spatial organization of the subject research facility, the Institute of Paper Science and Technology (IPST). Third, the spatial organization of the former building (before the move) and the present building (after the move) of IPST will be analyzed. Finally, conceptual models of the mechanism between the communication and the spatial organization will be drawn up.

  • This paper reports on the ACQA(Animated agent for Conversational Question Answering) project conducted at LIMSI. The aim is to design an expressive animated conversational agent(ACA) for conducting research along two main lines: 1/ perceptual experiments(eg perception of expressivity and 3D movements in both audio and visual channels): 2/ design of human-computer interfaces requiring head models at different resolutions and the integration of the talking head in virtual scenes. The target application of this expressive ACA is a real-time question and answer speech based system developed at LIMSI(RITEL). The architecture of the system is based on distributed modules exchanging messages through a network protocol. The main components of the system are: RITEL a question and answer system searching raw text, which is able to produce a text(the answer) and attitudinal information; this attitudinal information is then processed for delivering expressive tags; the text is converted into phoneme, viseme, and prosodic descriptions. Audio speech is generated by the LIMSI selection-concatenation text-to-speech engine. Visual speech is using MPEG4 keypoint-based animation, and is rendered in real-time by Virtual Choreographer (VirChor), a GPU-based 3D engine. Finally, visual and audio speech is played in a 3D audio and visual scene. The project also puts a lot of effort for realistic visual and audio 3D rendering. A new model of phoneme-dependant human radiation patterns is included in the speech synthesis system, so that the ACA can move in the virtual scene with realistic 3D visual and audio rendering.

  • What is the role of right and left-brain in creative thinking? The current study is to address this question. Two empirical studies were performed to answer the question. First one is regarding the divergent thinking and right-brain connection. Second one is regrading the convergent thinking and left-brain connection. Empirical study showed that both of divergent and convergent thinking were asymmetrically related to creativity. Divergent thinking was connected to right-brain and convergent thinking was connected to left brain.

  • Dualized program for building Public Administration scholarship in Korea has been, in a sense, a result of theoretical tension between the two positions, politics/administration dualism vs. politics/administration monism. The program has maintained its integrity by its dependence on a foundational question, "Is administration a different field of action from politics?" Korean community for the study of public administration has maintained its oneness by internally asking this question even though the two external philosophical positions were relatively indubitable. Strating from the well-known changes in the community, this brief outline for the future full exegesis tries to read carefully one point shown in the second chapter of one of the most seminal proposals for foundation of modern Public Administration, one paragrahp in the second chapter of "The Study of Administration" by Woodrow Wilson. What was the contemporary meaning of Wilson's classic distinction made in 1887? Keeping this research question in our mind, we will attempt to prepare for the full understanding of a kind of internal distinction Wilson explicitly draws between the constitutional and the administrative.

  • This research examines the impact of teachers' self-evaluation on their classroom interactions with students. Changes in class behavior were analyzed by following two experienced middle school teachers for one semester of self-evaluation, comparing their classes at the beginning and end of the semester. A qualitative research method was adopted to take, a deeper look at the effect of changes in the teachers' in class actions. Both of the teachers reported positive effects of implementing self-evaluation on their teaching pedagogy, focusing specifically on their interactions with students when asking question and giving feedback. By the end of semester, they were asking broader questions that encouraged their students to engage in deeper thought and, when giving feedback, the class atmosphere was much brighter with better communication due to the positive reinforcement provided. This research supports research into ways to enhance teachers' expertise and improve their teaching via self-evaluation, centering on teachers' actions in the classroom.
