Design And Implementation Of Employment Oriented Vocational Computer Teaching Resources Platform

With the rapid development of the global internet technology,there are more internet users,and the internet based educational information has been advanced a lot.Meanwile,the diverse network information service provides a great convernience for learners.However, how to make the secondory vovational school students not only get the interesting resource computer courses but also with employment closely together,becomes a problem that all the vocational education people pay close attention to.The integration of vertical search engine and resources platform are presented to sovle this problem.Above all,the system uses B/S model,and it uses JSP technology which is most popular currently.Moreover,it uses Flash Paper and FMS technology to realize the problem of the resources view and online play,implemented the file upload through the RandomAccessFile class of functions,and it also realizes the resources download through calling the setHeader method of the built-in response object.As for information retrieval,it uses Nutch+JE segmentation techniques to obtain resources of employment informations.The Nutch based crawler set the number of threads and the initial seed to meet the system query. Compared segmentation performance in some Chines word segmentation techniques through experiment,we selecte JE segmentation technology to do.Information netrieval inorder to achieve the employment information of query matching computer professional.Finally,the platform of vocational computer teaching resources have the user login module,resource service module,commucication module and the backstage database management module.The test results show that the system realizes the different users different operating,course uploading and downloading,questions,reply message,the various functions of management resources.The proposed system has interactive and good practicality.
