record information of readers in processes of using the library; and filtering out garbage data, and establishing a smart big
database of the library. According to the method, the
unstructured data, structured data and semi-structured
data information is collected and stored into the smart big
database, updating is carried out in real time, a
distributed computing architecture of Hadoop is adopted, big-data technology isutilized to mine, identify, organize and analyze the
data information which is implicit in reader behaviors, thus implicit appeals thereof are found, then services of the library are improved, two-way ideal control of library resources and the services and reader demand is achieved, and an
organization level of a library
