Abstract: Patent is a key knowledge base for product innovation design. The current patent knowledge model and retrieving pattern can not supporting technology innovation sufficiently. TRIZ is a kind of innovation methodology based on patent analysis and there is a congenital relationship between them. Innovation design oriented patent model is researched based on inventive principles, standard solutions, effect and other TRIZ tools. As a Computer Aided Innovation system, Innovation Engine is introduced and developed. The effectiveness is proved by the conceptual design of Cotton Picker. The patent knowledge of cross domain is used successfully by Innovation Engine.

Abstract: This paper proposed a spelling error detection and correction using the linguistic features and knowledge resource. The linguistic features mainly come from language model that describes the probability of a sentence. In practice, the formal document with typos is defective and fall short of the specifications, since typos and error hidden in printed document are frequent, rework will cause the waste of paper and ink. This paper proposed an approach that addresses the spelling errors and before printing. In this method, the linguistic features are used in this research to compare and increase a new feature additionally that is a function of Internet search based on knowledge bases. Combining these research manners, this paper expect to achieve the goals of confirming, improving the detection rate of typos, and reducing the waste of resources. Experimental results shows, the proposed method is practicable and efficient for users to detect the typos in the printed documents.

Abstract: In viewing of information overload environment,traditional search engine has inherent insufficiency about retrieval accuracy and query mode,together with the characteristics of decision tree algorithm and knowledge push,this paper presets an intelligent knowledge push model,and discuss the mechanism of this model.The model strive to improve the retrieval efficiency and realize the intelligent service.

Abstract: Based on the analysis of several methods of storing OWL object in relational database, this paper presents a new method, namely storing the instances of each kind of object and attribute in a database table, and using views in the database to express relationships among the objects. Experiments prove that this method is applicable for moderate amount of storage of OWL objects.

Abstract: It is presented the knowledge engineering based design process for tricone bits and the principles of intelligent design systems. Based on Teamcenter, using NX system development software, taking full advantage of the existing design standard, design data, and materials such as design experiences, design criteria, tricone bit models accumulated by industry companies, a knowledge driven intelligent design system for tricone bits has been developed. It is a way of effectively reusing industrial product development knowledge, enhancing effectiveness and quality of product design, and achieving product full life cycle management.

Abstract: Software evolution process model (EPM) is a knowledge-intensive process which is described in EPDL(Software Evolution Process Description Language) and modelled by semi-formal approach based on EPMM(Software Evolution Process Meta-Model). In order to support process improvement and process automation, the execution model is represented by logic programming. Activity in EEM (EPM’s execution model) is not implemented until its needing all kinds of resources are satisfied by system execution environment. The paper discussed the representations of all kinds of resources in EEM and their structures are proposed. The preparation resources method is presented in order to execute the EEM automatically. The converter program is realized and the correct results have presented to prove the correctness of the method.

Abstract: Software evolution process model (EPM) is a knowledge-intensive process which is described in EPDL(Software Evolution Process Description Language) and modelled by semi-formal approach based on EPMM(Software Evolution Process Meta-Model). EPM’s execution model (EEM) is represented by logic programming to create the knowledge base of EPM during constructing the EEM. Only its needing all kinds of resources are satisfied by system execution environment is activity in EEM implemented. The paper discussed the method and the algorithm of preparing resources is respectively presented in order to execute the EEM automatically. The converter program is realized and the correct results have presented to prove the correctness of the method.

Abstract: The paper designs the urban-rural power grid dispatching fault diagnosis expert system which acquires fault information by SCADA system of automatic system of urban-rural power grid, and uses artificial intellegence method to analyze fault information and make fault diagnosis. The paper implements the core part of the fault expert system—the design of knowledge base and fault inference engine.

Abstract: In order to improve the interoperability of XBRL format financial reporting on the semantic level, a novel XBRL financial reporting metamodel and a fact data semantic metamodel are proposed, which uses the Semantic Web technologies and Ontology theory. Then, a XBRL knowledge base is constructed based on this metamodel .Using the metamodel-based translation mechanism from XBRL to OWL / RDF, all the semantic information in XBRL taxonomy and instance documents is translated into OWL ontology and RDF instance. Finally, a knowledge base covering the semantic information of financial reporting domain is constructed.

Abstract: The current education of colleges and universities in Jiangxi province is in a critical period of development. The scale of students taking higher education has increased nearly 10 times from the late 1990s to 2013 in Jiangxi province. According to the international standards, Jiangxi has been in a stage of higher education popularization. Although the overall situation is optimistic, we should realize that the start of education in Jiangxi province is much lower. While teaching scale and quality having a substantial increase, there is still a certain gap in teaching level between Jiangxi and the developed countries. Recently, society has been shifting to the knowledge economy society gradually. Colleges and universities have to reform the situation of education under the guide of information technology. This paper analyzed the connotation of the knowledge-innovative talents. Through the AHP analysis method, the analysis model of knowledge-innovative talents was established to offer new ideas to the innovation of the teaching and improvement of management. for the higher education in Jiangxi province.
