Cloud Computing Oriented Retrieval Technology Based on Big Data

With the rapid development of cloud computing, the information increase rapidly. Cheap cloud storage and computing power accelerate the development of big data, and make the big data information collection and information retrieval become necessary. More than 50% of the big data is unstructured data, so it is stored in the form of file for the most part. Big data is divided into many blocks what stored in the server with some corresponding metadata of storage on the master server. How to collect the big data web and keywords and retrieve the information are been discussed in this paper.
