This paper discusses basic conceptions of content management, analyszes type and functions of Web CMSs.The paper also introduces and compares several open source Web CMSs, and gives some pieces of advice on how to select a suitable CMS.
The complexity of domain Ontology construction is discussed in this article. “Using the domanial property of concept in Ontological conceptual framework to describe, represent and construct domain Ontology” is also brought forward in this article. There is also an example of using domanial property of concept in order to eliminate lexical ambiguity in retrieval based on lightweight agricultural Ontology.
Based on the cataloging rules for metadata of rare books , this paper proposes a solution of Ontology-based knowledge base for rare books. Then, describes the whole framework and gives an implementation in prototype with the semantic Web.
This paper analyzes several systems and selects three of them which have common characteristics of medical data mining systems from the Medline.Then,discusses about the origin and implementation of these systems,and also investigates the technical methods and consideration on system design and implementation.At last,the paper summarizes the common and regular characteristics in system design and implementation,and provides useful references for future development.
In order to implement the metadata harvesting function in DSpace Repository System,this paper discusses how to integrate OAIHarvester2.0 software in dspace1.4 Repository System.
Conducting an empirical research through both experiment and survey, this paper studies a relationship among perceived risk, word-of-mouth information and information search, and puts forward an information presentation -perceived risk-information search model. At last, a revised model of information presentation-perceived risk-information search is presented.
This paper makes the research on technical characteristics of the pronunciation information content analysis and compares the difference with text analysis. The paper gives a summary of technology in pronunciation information content analysis, and emphasizes on the difficult technologies that includes speech recognition,emotion information recognition and speech recognition classification.
Information syndication based on RSS/Atom is a kind of important information service on Internet. This paper firstly introduces the general status of this service from the aspects of service, technology and commercial module,then discusses the service type and related technology,and points out the development trend of information syndication in the future.
This paper presents a personalized recommendation system by using Ontology and universal user profile. Firstly, the Website directory service is used as Ontology to identify user’s browsing behaviors on Internet to discover user preferences. Secondly, the redundant Web logs are filtered out by using Web usage mining technology , which can enhance the accuracy of personalization. Finally, from user preference directory, user’s potential preference is discovered by using the hierarchical property,that is,to bring out the universal user profile which match the characteristics of the user.
The analysis model of bipartite graph is to combine the content information on Web page and hyper-chain information, so as to provide an algorism based on classification method. By using bipartite graph,one can work out the Website’s maximum matching and complete matching. This method can also help excavate the implicit knowledge association and locate accurately the reasonable orientation of the users.
This paper investigates and implements three methods for document semantic orientation recognition: one is based on the weighted emotional words; another is based on the analysis of the semantic pattern; and the third is based on text classification. The first method is try to use semantic orientation of feature words. The second method is to simplify the structure of the natural language syntax, in order to acquire the appropriate size patterns with semantics tendency. The third method is based on the direct use of traditional text classification method. Through experiments and the application in an analysis system of net-mediated public opinions, shortages and advantages of the three methods are proposed.
In this paper,an approach for news article extraction from Web page is proposed and this approach applies information theory to DOM tree. Experiment on several news Web sites shows that it is practical.
This paper analyses the shortcoming of segmentation algorithm, designs a new algorithm for Chinese phrase segmentation. By building two levels index for Chinese thesaurus, we attain a highly efficient Chinese phrase segmentation thesaurus which supports hashing operation by means of the first Chinese character in a string and full binary search. Based on this thesaurus, we design a new algorithm for Chinese phrase segmentation.
Focused Web news aggregator is a new and practical direction in the field of information processing．This paper argues the principles, difficulties and measures of the focused Web news aggregating, and then analyses the design of the focused Web news aggregator．
This paper introduces the basic features of plone content management system. A case study on the CAS thesis & dissertation virtual working platform is explored, which indicates that content organized by category, workflow defining and user’s role and permission granting are key to the construction of the virtual working platform.
This article discusses some performance management methods, including performance monitoring, bottle-neck positioning, performance tuning, etc. Meaning while, the experience on performance monitoring and performance tuning of NSTL is introduced.
Statistic process of bibliometric is classified by statistic result. After concluding and analyzing various statistics, this paper shows that critical technology of these statistics is same, but there is some difference in dependence on basic statistic and form of output. Statistic is actualized by find and comparing in Excel using VBA, which is not supported with SQL. It is expected that papers of bibliometric can be written automatically and paper text can be analyzed deeply.
In this paper, an improved K-Nearest Neighbor (KNN) is proposed and is applied to filter spam email. It’s proved that the improved algorithm is less sensitive to the parameter K and the distribution of the training set, helps reducing the misclassification, and performances well in experiments.
Firstly this paper exposes server virtualization technology and software and then expands how to use virtual software VMware server to deploy and optimize Fuzhou University Library digital resources.
