    Big Data and Linked Data: The Emerging Data Technology for the Future of Librarianship
    Liu Wei, Xia Cuijuan, Zhang Chunjing
    2013, (4): 2-9.  DOI: 10.11925/infotech.1003-3513.2013.04.02
    Nowadays the ever growing linked data has broken through the restrictions between the triple structure and the relational model, and tend to use NoSQL approaches more often. More and more Big Data solutions provide semantic annotation and reasoning features.It brings machine readable semantics, rich meaningful linkage and knowledge analytics to the big data, and provide openness and interoperability to applications. The paper introduces the above background, makes difference between BIG Linked Data and LINKED Big Data systems, which the former implies the Big Data approach adopted by the Linked Data community, and the later vice versa. It also comments on the progress and benefit with the two cutting edge data technologies and gives outlooks on the future of the Big and Linked Data mashups.

    Research on RDB2RDF Standards and Applications
    Xia Cuijuan
    2013, (4): 10-17.  DOI: 10.11925/infotech.1003-3513.2013.04.03
    In this paper, the requirements of RDB2RDF mapping language, the logical framework, the syntax specification, the implementation solutions and the application outlook of W3C’s two RDB2RDF mapping languages, Direct Mapping and R2RML, are analyzed based on literal reviews and experimental investigations. With the standardized syntax,logical framework and the reasonable workflow,the two mapping languages are expected to enhance the data quality of RDB2RDF and promote the application of Linked Data.

    The Technological Features of Electronic Records Management Systems
    Chao Lemen
    2013, (4): 30-39.  DOI: 10.11925/infotech.1003-3513.2013.04.06
    The three main objectives of designing and developing an ERMS are identified based on analyzing the relevant works. Then, the differences between ERMS and MIS are described. Further,the three underlying technologies for the control, providence and service of ERMS are proposed, and their basic features, key technologies, and main challenges are described by taking GB/T29194-2012,MoReq2 and DOD5015.2 as typical examples. Finally, the main principles which can provide guidelines for developing ERMS applications are proposed.

    Research on Automatic Semantic Annotation for Geosciences
    Yao Xiaona, Zhu Zhongming, Wang Sili
    2013, (4): 48-53.  DOI: 10.11925/infotech.1003-3513.2013.04.08
    How to realize the automatic semantic annotation for a large number of information resources is one of the key issues of the construction of digital library based on the Semantic Web.For the professional documents of geosciences, this paper realizes the automatic semantic annotation based on the Semantic Web for Earth and Environmental Terminology(SWEET) and the General Architecture for Text Engineering(GATE),and proposes a method to map the RDF triples according to the domain and range of a property in domain Ontology.The results of the experiment verify the effectiveness of the method.

    Study on Text Language Recognition Based on N-Gram
    Wang Hao, Li Sishu, Deng Sanhong
    2013, (4): 54-61.  DOI: 10.11925/infotech.1003-3513.2013.04.09
    A language recognition program which is used to auto recognize the textures of the most popular languages on Internet including Chinese-simple, Chinese-traditional, English, French, German, Russian and Korean, is realized in this paper based on the N-Gram language module. The speech recognition experiments are divided into two stages of training of multilingual corpus and testing of language recognition, the texts of training and testing come from the Open Directory Project. The program is used to participate in the language recognition test, as well as to make contrast tests to another language recognition program based on N-Gram named TextCat. The result of the language recognition experiment proves that the program has a fine performance on recognizing Chinese-simple, Chinese-traditional and German, and the accuracy of recognition on Russian, French and English in the next place, the Korean is always interfered with Chinese in these experiments.

    Study on the Reviews Effectiveness Sequencing Model of Online Products
    Li Zhiyu
    2013, (4): 62-68.  DOI: 10.11925/infotech.1003-3513.2013.04.10
    On the basis of studying the influencing factors of online reviews effectiveness, a review effectiveness index system is established. The fuzzy analytic hierarchy process is adopted to determine the relative weight of indexes, various indexes of reviews content are quantized by semantic mining, and the total effectiveness score is calculated for each review. In terms of the model application of this study, nearly 2 000 reviews on a product of China’s Tmall are selected to make an empirical analysis. The study and comparison indicates that, after being processed by the sequencing model, a large number of useless reviews are postponed, and those reviews at the forefront of the new sequence are very rich in information content and high in effectiveness, and can assist consumers in making purchase decisions effectively.

    Research and Application of Flash Location-show Technologies for Library Collections
    Sun Fa, Liao Wenxian
    2013, (4): 90-94.  DOI: 10.11925/infotech.1003-3513.2013.04.14
    The location technology of library collections based on coordinate position of static picture and display of dynamic image can not separate the design of location interface from the implementation of location business logic, which result in heavy workload of the positioning data acquisition, poor results of location display and difficulty in updating and maintaining. To solve these problems, a development model and its implementation method of localization system of library collections based on Flash technology is proposed. Then the location system of books, CD-ROMs and seats of study room are designed and developed.
