And then, it discusses the pla ns of information integration between CAPP and CAD, as well as between CAPP and ERP. To design the processes of a product requires the manufacture information, such as blank material and machine tool, which is saved in a database in ERP. General ly, a traditional CAPP system considers the information of the manufacturing res ources, such as machine tool, as changeless. However, it is real changing, becau se the resources may be occupied or the machine tool may be under repair. Theref ore, in order to design the processes more reasonably, we must consider the real change of resources in a workshop. Creating a public resource database to suppo rt the real change of resources is put forward in this paper. With the public re source database, the resource integration between CAPP system and ERP is realize d; and by information collections in CAPP system, such as BOM, the material cons umption and man-hour consumption and their output to ERP, the information integ ration between CAPP system and ERP is realized.展开更多

CORBA enhances the system integration because it is an industry-standard for interoperable, distributed objects across heterogeneous hardware and software platform. Agent technology is used to improve intelligence of integration system. In order to implement the information integration platform, we use network integration server to integrate network, design a generic database agent to integrate database, adopt multi-agent based architecture to integrate application, and utilize wrapper as CORBA object to integrate legacy code.展开更多

But it is ubiquitous that schema semantics of information is identical while the interpretation of it varies with different context, and ontology-based semantic information integration can not resolve this context heterogeneity. By introducing context representation and context mediation to ontology based information integration, the attribute-level context heterogeneity can be detected and reconciled automatically, and hence a complete solution for semantic heterogeneity is formed. Through a concrete example, the context representation and the process in which the attribute-level context heterogeneity is reconciled during query processing are presented. This resolution can make up the deficiency of schema mapping based semantic information integration. With the architecture proposed in this paper the semantic heterogeneity solution is adaptive and extensive.展开更多

The architecture takes the frame structure as single link among applica- tions and between applications and physical storage. All the advantages in form features based inte- grated systems can be found in the frame-based architecture as the frame structure here takes form fea- tures as its primitives. But other advantages, e.g., default knowledge and dynamic domain knowledge can be attached to frames and the frame structure is easy to be changed and extended, which cannot be found in form features based systems, can also be showed in frame based architecture as the frame structure is a typical knowledge representation scheme in artificial intelligence and many researches and interests have put on it.展开更多

INTRODUCTION Changbai Mountain is situated between E127°54′-128°08′, N40°58′-42°06′ about 2700 meters above sea level. It is the typical area of the mountainous climate in the monsoon area of the temperate zone on the globe. The well reserved primeval vertical distribution of natural landscape belts and the Natural Conservation of Changbai Mountains adopted by the UNESCO′s MAB Program cause the worldwide attention of geographers. Beside the complexity of the climatic structure itself, the mechanical effection of the high mountain body also effect the climate in the eastern part of China. In the mountain area where short of meteorological observation data, the climatic study by remote sensing is favorable for discovery and representation of climatic law in large area.展开更多

The enterprise integration model depending on encapsulating the business processes as well as the enterprise applications by the neutral and standard web services is presented. The problem how to discover the existed enterprise resources and share them was resolved depending on the mechanism of publishing and discovering the services. The EIP is integrated closely with product lifecycle management (PLM) system so that the process integration as well as orchestration of the business process services is implemented by encapsulating the workflow engine of PLM system. Not only process integration and application integration, but also information integration based on the bill of material (BOM) conversion driven by process are achieved. Finally, an interpretive, qualitative case study on EIP is conducted for this research.展开更多

The article begins by examining the diverse perspectives among both the cognitive and AI researchers regarding ChatGPT’s ability to pass the Turing Test. It introduces a hierarchical categorization of the test versions, suggesting that ChatGPT approaches success in the test, albeit primarily with na?ve users. Expert users, conversely, can easily identify its limitations. The paper presents various theories of consciousness, with a particular focus on the Integrated Information Theory proposed by Tononi. This theory serves as the framework for assessing ChatGPT’s level of consciousness. Through an evaluation based on the five axioms and theorems of IIT, the study finds that ChatGPT surpasses previous AI systems in certain aspects;however, ChatGPT significantly falls short of achieving a level of consciousness, particularly when compared to biological sentient beings. The paper concludes by emphasizing the importance of recognizing ChatGPT and similar generative AI models as highly advanced and intelligent tools, yet distinctly lacking the consciousness attributes found in advanced living organisms.展开更多
