| Summary: | 碩士 === 國立中正大學 === 資訊工程所 === 98 === Because the Internet is closed to personal life , and using mobile devices to connect Internet is more and more universal . So far , there are two kind of method to search data from internet . First , using internet search engine. Second , messages posted on the discussion forum . However , these methods have drawbacks . The first kind of method can only find the history file. The weakness of second method is the waiting time. User have no idea when the question can be answered. Both the methods cannot guarantee to support the correct data for user in short time. In this paper , according to real-time service and mobile mutual concept , we develop a service of platform . The primary idea is that system finds the appropriate people to answer the question in the short time. In the implement side , we use hadoop which is a distributed platform and HBase which is a distributed file storage system for handling more people . In addition , we establish many mechanisms for finding appropriate people . In the experiment side , we do two performance tests . One is different number of computers , and the other is different number of data . Finally , we support some future .
