Semantic Analysis of Natural Language Queries for an Object Oriented Database

This paper presents the semantic analysis of queries written in natural language (French) and dedicated to the object oriented data bases. The studied queries include one or two nominal groups (NG) articulating around a verb. A NG consists of one or several keywords (application dependent noun or value). Simple semantic filters are defined for identifying these keywords which can be of semantic value: class, simple attribute, composed attribute, key value or not key value. Coherence rules and coherence constraints are introduced, to check the validity of the co-occurrence of two consecutive nouns in complex NG. If a query is constituted of a single NG, no further analysis is required. Otherwise, if a query covers two valid NG, it is a subject of studying the semantic coherence of the verb and both NG which are attached to it.

A Comparative Study of the Value Orientations of Foreign Language Education Policies in China and the United States in the 21st Century

Since the 21 st century, both Chinese Mainland and the United States have formulated foreign language education policiesbased on their national needs. This paper makes a comparative study of the value orientations of foreign language education poli-cies in Chinese Mainland and the United States in the 21 st century and finds that both China and the United States have regardedtheir national interests as the essential value orientation of their foreign language education policies. To be specific,the core valueorientation of foreign language education policies in China is to enhance its cultural soft power.In contrast,the core value orienta-tion of foreign language education policies in the United States is to safeguard its national security. Through the comparison of thedifferent value orientations of foreign language education policies of the two countries, the paper provides some reference for the for-eign language education policy-making in Chinese Mainland.

Integrative and Instrumental Motivational Orientations of English Language Learning

As a key predictor of learners’language achievement,motivation has long been an active research area in second language acquisition.Among assorted theories,Gardner’s perspective is one of the foundations of L2 motivation research and thus has dominated this field for a long time.Do?rnye later put forward the L2 Motivational Self System to reconceptualise Gardner’s notions.The current essay attempts to reflect on the concepts of integrative and instrumental motivational orientations discussed in both Gardner’s and Do?rnyei’s theoretical frameworks in order to gain a subtler understanding of the role of these two notions in L2 motivation.

Agent Oriented Programming进展

Agent-oriented programming (AOP) is a framework to develop agents, and it aims to link the gap betweentheory and practical in agent research. The core of an AOP framework is its language and semantics. In this paper,we propose the necessary properties which agents should have, and then give a summary and analysis about differentAOP languages based on these properties.

A Brief Analysis on the Relationship of Language,Culture and Translation

In recent years,it has become a hot topic for researchers to explore the relationships between language and culture,language and translation,or culture and translation.Indeed,the three aspects are inseparable.Language is the carrier of culture and also restricted by culture.Translation mostly takes place between languages and it is a kind of cross-linguistic and intercultural communicative activity.While translating,it is necessary to understand thoroughly the two languages,but also two cultures and cultural differences between them.In this paper,I firstly give a general review on both the conception of language,culture and translation and their relationship and then discussed the interaction and blending separately from the two phenomena of culture-orientation in translation and translation under culture context.Since culture is transmitted mostly by language,cultural elements and factors should be taken into consideration in translation practices.To achieve the goal of translation in a real sense,translation practices should be based on the principle of processing the discourse of source language and target language under the perspective of its cultural context.

Aspect-oriented software reverse engineering

To solve the identification and comprehension problem of crosscutting concerns in existing legacy software system, a framework of aspect-oriented software reveme engineering is proposed. An approach on re-modularizing traversal features of legacy system is presented based on various unified modeling language （UML） diagrams. While modeling crosscutting concerns in UML use case diagrams, the non-functional requirements that affect several use case modules can be enveloped into aspect modules with a stereotype mechanism. The recurring message transmission patterns can be re-modularized as aspects in UML sequence diagrams with UML collaborations. Standard UML activity diagram notations are extended and modified by node fusion and addition, which support the graphical composition operation between crosscutting behaviors and primary business roles of concurrent systems. Case study indicates that travernal features of software system can be extracted and re-modularized from various perspectives in aspect-oriented reverse engineering, which improves comprehensibility and maintainability of legacy systems.

An Analysis of Space Language in an Intercultural Setting

With the constant acceleration of globalization,cross-cultural communication has become an important part of people’ssocial activities.Spatial language is the main content of non-linguistic communication in cross-cultural communication.Differentcultures have their own special spatial language rules.This study mainly expounds the differences and problems in spatial languagebetween east and west under cross-cultural background from the aspects of personal space,attitudes towards crowding,house orien-tation and classroom layout.The purpose of the study mentioned above these problems in the hope that readers can realize that theimportance of spatial language in intercultural setting.

New Refinement Relations of Z Specifications for Multiple Viewpoints Oriented Requirements Method

In this paper we develop several new refinement relations of Z for multiple viewpoints oriented requirements method (MVORM). The original motivation is that we found the standard Z refinement relation is not adequate or correct when considering specifications that have temporal relationships of operations. The concept of temporal state variables is introduced into Z. Then new implementation relations are defined and new refinement relations are deduced, mainly for temporal state variables to process temporal relationships of operations. We use state transition systems to abstract the temporal state transitions. A simple example is used to show the procedures of MVORM. Finally some directions of further work are forwarded.

The Impact of Recasts on Second Language Acquisition

The roles of recasts have been intensively studied in the first language (L1) research. This essay explores the role of recasts in second language acquisition, mainly focusing on discussing the studies addressing the following two issues: (1) the effects of recasts on the interaction of communication oriented classroom; (2) the role of recasts in promoting interlanguage development.Mixed evidence has been presented by second language (L2) studies regarding the impacts of recasts on second language acquisition.

Spiritual Language of Public Art in Architectural Form

To interpret spiritual language of architectural public art, architectural form was analyzed. Visual art space is based on spatial vision, artistic forms of point, line, surface and body are major visual elements of spatial form. Visual elements can be demonstrated in various forms, and even more diversified in the context of spatial design, interact with each other according to the form principle of beauty, and construct artistic forms of the space. Manifestation of the nature of public art also relies on visual elements, and the public aesthetic experience and feelings about architectural public art are expressed by visual elements.

Context-aware BPEL workflow system using aspect-oriented programming

Business process execution language(BPEL)is a most recognized standard workflow language.However,it is difficult to be used in the ubiquitous system computing environment because it is difficult to describe the context information in the selection of the flow through the branch.To solve this problem,we propose a new BPEL workflow system with context-awareness by using aspect-oriented programming(AOP).This system is composed of a BPEL system module and a weaving module using AOP for context-aware.The BPEL system module generates a BPEL workflow program.And the weaving module converts a context-aware mark-up language(CAML)document to the aspect-oriented program that is applied to context-aware code without modification of the existing BPEL document.We also define a new document form that is called CAML,which provides a context-aware that is not available in BPEL.The system can generate a context-aware workflow program.It is developed in a way that inserts context information using AOP to provide context-aware services.

An Embedded Software Modeling and Process by Using Aspect-Oriented Approach

In recent years, mobile devices have become widespread and refined, and they have offered increased convenience in human life. For these reasons, a variety of embedded systems have been designed. Therefore, improving methods for developing of embedded software systematically has become an important issue. Platform-based design is one example of an embedded-system design method that can reduce the design cost via improving a design’s abstraction level. However, platform-based design lacks precise definitions for platforms and design processes. This paper provides an approach that combines the aspects and platform-based design methods for developing embedded software. The approach is built on platform-based design methodology and uses the separating of concerns (SoC) concept to define the aspects and to reduce the crosscutting concerns in embedded system modeling. For aspect issues, we use the extended UML notation with aspects to describe both the static structure and the dynamic structure of the embedded system. We used an example of a digital photo frame system to demonstrate our approach.

Object-Oriented Finite Element Analysis of Metal Working Processes

Recently an object-oriented approach has been applied in the fields of finite element analysis with a view to treating the various complexities within these. It has been demonstrated that finite element software designed using an object-oriented approach can be significantly more robust than traditional codes. This paper describes a special kind of implementation of object-oriented programming which is rather hybrid in nature, in the development of a finite element code for engineering analysis of metal working problems using C++, and discusses the advantages of this approach.
