    2012, (11): 22-33.  DOI: 10.11925/infotech.1003-3513.2012.11.05
    Abstract   HTML   PDF (720KB) ( 550 )
    The objective of this study is to evaluate security issues of cloud testing. Organizations are increasingly moving to the cloud and sharing their information, but there are concerns about security issues and risks that may arise due to security breaches. This paper extends the concept of security approach during testing. It makes use of a literature review to evaluate the risk of eight security issues when testing in public clouds. The security issues including trust, governance, compliance, identity and access management, availability, data security, instance isolation and its failures, and architecture in testing on a public cloud. The paper also includes an empirical survey to evaluate the current security strategies of different public cloud providers on the eight security issues.

    Abstract   HTML   PDF (1023KB) ( 625 )
    This paper makes research on a solution to the construction of cloud computing platform for software testing. It first proposes the hierarchical model and the system architecture, and then discusses the approaches to building a cloud computing platform for software testing by using the open source software techniques, including IaaS and PaaS. In implementing these approaches, the authors first list out the software and hardware specifications of the IaaS platform, then describe the installation and configuration of the OpenStack, and illustrate the configuration of virtual testing servers. The authors also present the deployment of the PaaS, which includes the design and implementation of software testing project management tool on cloud computing, the calling method of IaaS resources.

    Research of Mining the Category Knowledge Based on English-Chinese Humanities and Social Sciences Parallel Corpus in Phrase Level
    Wang Dongbo, Han Pu, Shen Si, Wei Xiangqing
    2012, (11): 40-46.  DOI: 10.11925/infotech.1003-3513.2012.11.07
    Abstract   HTML   PDF (769KB) ( 452 )
    The experiment of mining the category knowledge from English-Chinese humanities and social sciences parallel corpus in phrase level is performed based on the established clustering algorithm. The clustering and morphological conversion algorithms are determined by experimental data and specific research needs. The performance of English-Chinese bilingual word features is better than monolingual word by comparing the performance of the Chinese, English and English-Chinese word level knowledge clustering. The category knowledge is directly applied to knowledge base and machine translation system, and the English and Chinese word's expression is explored in mining the category knowledge.

    Study on New Technology Detection in Patents Documents
    Gu Jun
    2012, (11): 53-59.  DOI: 10.11925/infotech.1003-3513.2012.11.09
    Abstract   HTML   PDF (611KB) ( 273 )
    This paper promotes a method which detecting new technology term from the texts of Chinese patents. Firstly, the element of terms in patents are extracted by ICTCLAS segmentation system and stop words lists. Then the hot elements of terms are filtered based on terms weights computing by improved TFIDF model. Secondly, the hot elements of terms are combined orderly by computing the distance between two words, and obtain the terms collection by terms weights computing and threshold filtering. The valid new technology terms are detected by the experts artificially. Finally, the availability of the method is proved through the applied example.

    Abstract   HTML   PDF (537KB) ( 288 )
    In order to get similar patents from patent databases, based on merging similar concepts on Ontology-based identification replacement, this paper constructs a vector space model by estimating the TFIDF values of the concepts, and eventually gets a collection of similar clause on similarity matching sentences by orderly longest common subsequence identification method to match the results of previous similar patent document extraction. This method can help enterprises intelligence detect similar patents effectively.

    A Method for Detecting the Hot Topic of Literature Based on Lifecycle——A Case Study of Neoplasm Field
    Zhao Yingguang, An Xinying, Li Yong, Jia Xiaofeng
    2012, (11): 86-91.  DOI: 10.11925/infotech.1003-3513.2012.11.14
    Abstract   HTML   PDF (696KB) ( 348 )
    There are some shortcomings of hot topic detection in literature,such as single index and the inefficient filtering of high-frequency common words. The paper applies lifecycle theory and TF*PDF algorithm to literature detection, which finds the hot words by tracking the variation of words over time, then locates the time hot words appeared. The results of the empirical tests show that this approach is effective in filtering high frequently used terms and identifying hot research topics in time windows.
