Hierarchical RNN with Static Sentence-Level Attention for Text-Based Speaker Change Detection
Speaker change detection (SCD) is an important task in dialog modeling. Our
paper addresses the problem of text-based SCD, which differs from existing
audio-based studies and is useful in various scenarios, for example, processing
dialog transcripts where speaker identities are missing (e.g., OpenSubtitle),
and enhancing audio SCD with textual information. We formulate text-based SCD
as a matching problem of utterances before and after a certain decision point;
we propose a hierarchical recurrent neural network (RNN) with static
sentence-level attention. Experimental results show that neural networks
consistently achieve better performance than feature-based approaches, and that
our attention-based model significantly outperforms non-attention neural
networks.Comment: In Proceedings of the ACM on Conference on Information and Knowledge

Social, cultural, and political constructions of Corporate Social Responsibility in China: A study of business discourses in the Fiberhome Technologies Group
Abstract
This thesis focuses on corporate social responsibility (CSR), a vital issue for both business and academic researchers, and examines how the reality of CSR is socially constructed within a Chinese social, political and cultural context. In particular, this thesis examines understanding and practice of the discourse of CSR within a large Chinese State-owned enterprise (SOE), FiberHome Technologies Group (FHTG). It explains how cultural and political factors contribute to the production and development of CSR discourse in China. It also scrutinises social practices of corporate social performance, especially employer-employee relationships, within FHTG by investigating both the actual knowledge of CSR that FHTG publishes on its headquartersâ homepage and the research participantsâ interpretation of management construction of CSR discourse.
Website documents produced by FHTGâs headquarters from 2006 to 2008 were collected and 33 participants (managers and employees) from five headquartersâ departments and six subsidiary companies were interviewed for this study. Participants were selected according to the extent of their work experience with at least one year of work experience being a minimum requirement. Website information and interview transcripts were analysed using Faircloughâs (1992) three-step approach to CDA to examine how the knowledge of CSR is constructed and reproduced by organisational members and how it shapes the ways in which the social reality of Chinese CSR is constructed.
The thesis argues that the reality of Chinese CSR is shaped by the Chinese cultural system of Confucianism focusing on human virtues, as well as government adoption of some Western CSR initiatives. The research findings suggest a hybrid form of business management model by embracing both a Chinese management and a Western management style into business practice. The Chinese management style constructs a discourse of Confucian entrepreneurship which forms a distinctive feature of Chinese CSR practices, focusing on the development of human virtues that guide companies to a new way of improving their CSR performance. Also, the adoption of a Western management style exhibits a giving discourse that considers the interests of stakeholder groups including employee, government, community and society. In addition, the research findings suggest that employeesâ understanding of CSR is shaped by FHTGâs social performance and is similar to the management construction of CSR discourse. Their definition of CSR involves three key aspects: social harmony, employee welfare, and economic benefits.
This thesis contributes to knowledge from three perspectives: theoretical, methodological and managerial. Theoretically, this thesis contributes to the development of Chinese CSR theory. This theory promotes economic productivity as a means of achieving social wellbeing and employee wellbeing. Methodologically, this thesis offers a benchmark for the study of CSR discourse by using a face-to-face interview method which has previously rarely been used in research on CSR in a Chinese context. Managerially, this thesis provides a guide for government officials and business managers to design the strategies based on their own countriesâ cultural, political, economic, social and institutional frameworks
Error Analysis on English Writing of Chinese Mongolian Students Based on Automated Scoring System
A Corpus plays an important role in English writing. Corpus can provide students with rich authentic materials. The automated scoring system which is set up based on the use of corpus, such as the automated scoring system of Ju Ku, can grade the composition and make an analysis of studentsâ English writing to help them correct their writing errors. In this paper, an investigation of the writing problems of Mongolian students is carried out to make an analysis of the errors that students are easy to make in an attempt to improve Mongolian studentsâ writing abilities
The Influence of Learnersâ Motivation and Attitudes on Second Language Teaching
Learnersâ motivation and attitudes have great impact on the second language learning and teaching. This thesis first introduces the theories concerning learnersâ affective factors and then gives a brief definition of motivation and attitude .In order to reveal the co-relation between motivation and attitude of language learners and the second language teaching, the research designs two questionnaires to investigate the studentsâ learning attitude and the attribution for success or failure. Through discussion of the two surveys, the teaching tips in respect of a learnerâs motivation and attitude are recommended with the purpose of eliminating studentsâ negative emotional reactions as well as developing studentsâ autonomous learning abilities. In summary, this paper intends to improve the teaching effect by means of exploring the influences that a learnerâs motivation and attitude bring about to foreign language teaching
