Abstract


With the rapid development of Internet technology , the network also will rapidly increase. To bring people to more information at the same time , but also greatly increase the cost of the operation and management of the Internet companies . To solve this problem , a new type of IT technology development , deployment and business model , which is cloud computing technology . At present , the cloud computing technology in the network storage , search engines , distributed computing , e-commerce , social networking and other fields has been widely used , and has achieved rapid development . However , cloud computing also not an authoritative definition and uniform standard , the major IT companies in their respective business areas to investigate on your own . The search engine is the frontier of the Internet industry for large-scale data processing , and cloud computing technology will play an irreplaceable role in its development process . Traditional search engine keyword matching technology to search, can not really understand the user's query intent on the basis of the search , the lack of semantics . Therefore, the use of cloud computing technology and language processing technology to search technology to improve search engine will be a good way . The subject based on the introduction of cloud computing and search technology to discuss the shortcomings and deficiencies of the traditional search techniques . Research and design point of departure , a distributed cloud-based semantic search method , and focus on cloud-based distributed storage system ( CDSS ) conduct in-depth research and design . The advanced nature of the research work is mainly reflected in the following three aspects : (1) establish a consistent hashing data distribution and positioning algorithm based on virtual ring . With this algorithm , the system will speed up the data storage and access , while improving the load balancing capabilities of the system . (2) proposed a fully distributed data backup solution . Through this program , the system can rely on the advantage of the DHT network , to achieve fast synchronization of data copy and update , improve data availability , reliability and security . (3) based on the the CDSS semantic search algorithm . Covered by cloud-based distributed storage system on the semantic layer , to achieve semantic search in the DHT network .
