摘要：Traditional research in automated negotiation is focused on negotiation protocol and *** paper studies automated negotiation from a new point of view, proposes a novel concept, namely negotiating agent, and discusses its significance in construction of automated negotiation system, with an abstract model formally described and the architecture designed, which supports both goal-directed reasoning and reactive response. A communication model was proposed to construct interaction mechanism used by negotiating agents, in which the negotiation language used by agents is *** communication model and the language are defined in a way general enough to support a wide variety of market mechanisms, thus being particularly suitable for flexible applications such as electronic business. The design and expression of the negotiation ontology is also discussed. On the base of the theoretical model of negotiating agent, negotiating agent architecture and negotiating agent communication model (NACM) are explicit and formal specifications for the agents negotiating in an E-business environment; especially, NACM defines the negotiation language template shared among all agents formally and explicitly. The novelty of the communication model is twofold.

摘要：This article focused on the application of ethnography as a qualitative study in developing non-English majors’intercultural communication competence(ICC).The PEER model guided student researchers through the interdependent phrases of preparing,engaging,evaluating and reflecting in the research *** addition,the four components of Byram’s ICC model,namely,knowledge,skills,attitudes,and critical awareness,were used to assess students’ICC development.

摘要：In response to the challenges faced by the peer feedback,this research is to investigate how to develop peer feedback literacy,a much less discussed area from the previous *** the new literacy approach to analyze a case study in a Chinese college,the framework of peer feedback literacy for Chinese learners is developed in three dimensions:affect,knowledge,and communicative *** them,knowledge on peer feedback includes understanding rubrics,making judgements,giving advice,and using *** research was conducted among 25 first-year English majors in a semester-long writing course,where the peer feedback was done five ***,semi-structured interviews,and in-text peer comments in learners’assignments were collected for analysis and *** is found that the introduction of well-designed rubrics and the teacher’s modelling helped develop peer feedback literacy,and largely solved some problems arising in peer feedback,such as learners’ignorance of content feedback,their distrust of peers’comments,and Chinese learners’unwillingness to point out the problems due to face-threatening.

摘要：A point on the distinction between design and science is given and the connotanons of aeslgn science are discussed in the paper. Design should be understood as the first step of all human＇ s purposeful activity, which is a daily behavior for everyone. Four laws are summarized, which describe the basic patterns of design and are the constituents of design science. They are the law of design based on existed knowledge, law of in- completeness of design knowledge, law of design centered on new knowledge acquirement and law of competi- tiveness of design knowledge. The four basic laws show the knowledge essence of design. To enrich the existed knowledge, to make it convenient to be used, to teach designers with high intuition and inspiration in picking useful elements of existed knowledge and shaping competitive ideas and to have strong new knowledge acquire- ment facility are the basic conditions of good designs. Study of design science will promote the structure of tra- ditional engineering education. An important conclusion is derived that there will be no successful innovation without good design.

摘要：Assessment is an important part of learning process. It can be defined as the process of gathering information for the purpose of making judgments about a current state of affairs presumably for the purpose of enhancing future outcomes [1]. It determines whether or not the goals of education are being met. Typically, most assessment tools give a numerical score as the result of the assessment. This may not be enough to improve the student’s progress. In this paper we defined main problems in current assessment tools and proposed a new assessment model that uses notions in knowledge space theory to overcome the shortage of the current assessment models. The experiment result showed that this new prototype made the assessment process easier and more effective. However, assessment affects decisions about grades, instructional needs and curriculum. This is an important phase of the learning process being showed in this paper in knowledge states framework. Future research will focus on making the tool behave intelligently to improve students’ learning momentum.

摘要：In the proposal, a construction project memory process based on the semantic annotation is presented. A project Mem-ory concerns the representation and the identification of the experience acquired during projects realization. The main feature of this approach is that the semantic annotation is used to build a continuous semantic design rationale process. We propose in this paper, a semantic traceability in four stages (identifying, structuring, annotating and integrating). The identification and the structuring phases use a model called Extended Marguerite model which fully considers the objectives of the project memory. The annotation phase exploits the results of precedent phase to prepare the final phase. Examples are presented from a case study in an Algerian firm called ENMTP. The architecture supporting the modelling engine is presented. Finally, an evaluation of the degree of the semantic annotation brought by proposed process is given.

摘要：数据字典DD是数据处理系统结构化分析方法的重要工具之一.在DD中,各数据元素之间应能相互匹配,并应与数据流程图DFD中各元素一一对应.DD与DFD分别以文字和图形的方式描述系统,因此DD更有利于计算机的数据表达.若对DD的内容描述更进一步地细化和扩充,采用人工智能AI的方法来实现人的感知行为活动和推理的智能化数据字典,那么DD即可成为一份通过系统分析和设计而产生的系统的详细说明文档.为此,本文就智能化数据字典的知识库的建立,以及实现其推理机制、知识获取和实用数据处理系统的功能优化等问题进行讨论。
