This paper compares and analyses the technical characteristics and the solutions to the cloud computing adopted in some current representative enterprises. It summaries that cloud computing is a computing platform that supports for virtualization, dynamic resource pool and high availability, and cloud computing includes two aspects of the meaning such as the low-layer infrastructure and the application based on it. Through the integration of both Eucalyptus system and Liferay system, the detailed building process of the application-specific cloud platform is described. Creating the Linux-based service-customized Amazon Machine Image(AMI) file by the Xen virtual tools in the virtualization-based cloud platform, and starting and running the virtual machines by AMI tools are introduced with an emphasis to let readers capture the building process of cloud platform and rapidly deploying and migrating the application.
Based on a review of classical documents in the field of foreign usability research in the past few decades, this paper systematically analyzes the evolvement of the concept of usability, as well as the development of its evaluation system and evaluation method. Then it focuses on the usability of website, which is one of the most hot spot in this field of latest years, and reviews the development of research in this specific field.
Taking Term Tree 2000, MultiTes Pro 2007 and WebChoir TCS-10 for example, this paper investigates their configurations relating with four aspects such as thesaurus input and output, term disposal and control, term relationship disposal and control, thesaurus retrieval and display. Characteristics and drawbacks of the softwares are summarized and reasonable recommendations are proposed.
Concerning about the problem that various resources gates brings unsatisfactory user experience, the paper discusses library’s digital resource integration platform based on SOA. It introduces the integration object and system structure,and an integration platform has been designed and developed with visual studio.NET(C#). It discusses the application of SSO and how to choose and use open source software component in detail.
This paper analyzes the meaning and feature of research front, then it introduces some approaches based on citation analysis and theme words irrespectively. In the end, it concludes the advantages, disadvantages and application environment of these approaches.
This paper introduces the FRBR model simply， and emphasizes on the application of FRBR and some foreign systems, such as AquaBrowser Library, FRBR Display Tool, VisualCat, Virtua based on the aspect of information organization and information describing. It specially analyzes and compares the FRBR function, FRBR arithmetic, FRBR key problems of these systems. It aims to produce some results and references for ordering deep of information organization.
The tags added by users are free rein and uncontrolled in folksonomy systems,so the porter stemming algorithm is introduced firstly in this paper to extract the roots of English tags. Then the method of clustering English tags is brought forward, which chooses the precision following the user’s choice. Finally, making use of the tag cloud, simulation experiment is conducted and proves that this algorithm can make the English tags clustered according to the user’s requirement and describe the resource better.
This paper puts forward a kind of labelling method according to the Web page sense of vision information, which is also based on the inquiry connection pattern labelling method.Then it uses ontology phrases to replace the original label information, and the replacement of label information can ensure the labelling information uniformity.This method is a good way to make up the defects of original method,and effectively improves the precision and recall.
This paper proposes an approach based on query expansion and node aggregation under the unstructured peer-to-peer network. This approach can find the relationships of keywords and nodes automatically, then it records the information on each local node and updates its knowledge base continuously. In the future retrieval, the purpose of keywords relationship is to increase hit goals，and the purpose of similar nodes aggregation is to decrease the search scope. Simulation experiment results prove that this approach has high search hit rate and accuracy.
This paper introduces the research of an available method to automatically extract high quality translation pairs from patent database for patent resources. It analyzes the features of URLs to extract detail Web pages of patent data for batch downloading, and then uses regular expression matches to extract necessary information from Web pages through page parsed. At last, it makes bilingual parallel corpus after merging data.
This paper designs and implements an intelligent data gathering system for virtual community Social Network Analysis（SNA） based on Web data mining principle. It describes the system design and model implementation in details. Finally，the system is tested on BBS of Suzhou Computer Education Forum. The testing result shows that this system has enhanced the data gathering procedure substantially and can generate relational data in compliance with the specification of the most popular SNA softwares.
This paper starts from the sham battle intelligence information, and uses the method based on pattern matching to extract sham battle intelligence information.In different steps of information extraction, hierarchical text categorization method is used to filter the target text; seed pattern bootstrapping method together with field dictionary are used to recognize the sham battle blocks; corpus-based method is used to learn and acquire the event patterns.The experimental result shows that this method is effective in special application field, and it is usable in real projects.
In accordance with the actual demand of eResearch for the centralized and special-interest mode, the weakness of existing academic resources sharing mode is analyzed, and a plan for the academic resources sharing system in eResearch is brought forward based on centralized P2P model. The implementation methods of system architecture, system database, the modules both at the server and the client are given. This system is an inseparable part for eResearch of comparative linguistics in E-Institutes of Shanghai Universities，and it is user-friendly and extendible. The present study of eResearch is in the preliminary phase in China，and it offers some intelligent supports for eResearch.
The paper introduces the new retrieval functions of Web of Knowledge after updating in October 2008, including Scientific WebPlus，Citation Map, and ResearcherID. It provides a reference to make scientists, researchers, library and information officers know and use the new edition Web of Knowledge deeply.
On the basis of navigation mode of bibliographic subject classification of online bookstores, the paper constructs a navigation system of bibliographic subject classification of library OPAC, and describes the structure of the system and the classification of library bibliographic implementation in detail. Through a highly effective experiment,it not only enriches organization of bibliographic information, but also is accordance with user cognitive psychology and understanding of information.
This paper firstly summarizes the insufficiency of library resources evaluation in universities. Then, based on the practice in the authors’library, this paper introduces the design ideas，design and implementation key technology of a Web-based survey system.
