Abstract

The invention discloses a method and a system for multi-level cache management of scientific and technological intelligence data. The method comprises the following steps: collecting scientific and technological intelligence data, wherein the scientific and technological intelligence data includes the actual query visit volume of keywords, and the keywords in recent scientific and technological documents. accounting for weights; predicting the next cycle of scientific and technological intelligence users searching for hot keywords and their visits; managing data stored in multi-level caches, which include memory, network memory, solid-state drives and disks. The invention firstly predicts the amount of visits in the future cycle based on the method of machine learning; secondly, the value of the cached data required for each keyword is estimated according to the amount of visits, the size of the data and the user experience function; In the cache, the management of multi-level cache not only improves the speed of users' scientific and technological intelligence search, but also improves the user's query access efficiency.

Description

technical field [0001] The invention relates to a method and system for multi-level cache management of scientific and technological information data, belonging to the technical field of communication. Background technique [0002] Scientific and technological information has played an important role in the formulation and implementation of national, social and corporate strategies and plans. With the rapid development of science and technology, the demand for intelligence information is more urgent in various industries and departments in society. Scientific and technological information is considered to be a key link in economic construction, scientific research, design, production, operation management, and marketing. [0003] The scientific and technological intelligence database is an important source for scientific research workers to obtain scientific and technological information. When users use the scientific and technological intelligence database, they hope to obt...
