Embodiment Construction
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
[0020] The method for providing satellite remote sensing services based on knowledge services according to an embodiment of the present invention includes the following steps:
[0021] S1 integrates satellite remote sensing data to generate core knowledge, and builds a knowledge agent on the basis of core knowledge. The knowledge agent has the function of actively recommending knowledge to users, which can be understood as the transformation of knowledge from people's active retrieval of knowledge Actively retrieve people, knowledge agents classify satellite remote...

The invention discloses a satellite remote sensing service providing method based on knowledge service, and the method comprises the steps: fusing satellite remote sensing data, generating core knowledge, constructing a knowledge agent on the basis of the core knowledge, classifying the satellite remote sensing data by the knowledge agent, and constructing a knowledge service platform; completing the user analysis through a content-based recommendation algorithm and a collaborative filtering algorithm; and enabling the knowledge agent to perform corresponding analysis and adjustment according to user feedback. According to the satellite remote sensing service providing method based on the knowledge service, people actively retrieve knowledge can be converted into knowledge actively approaching a user, the demand of the user for certain data is predicted by trying to predict the service possibly needed by the user through a label selected by the user, and according to the behavior of the user and a feedback adjustment strategy, a recommendation result better meeting user requirements is generated.
Description
technical field [0001] The invention relates to the technical field of knowledge services, in particular to a method for providing satellite remote sensing services based on knowledge services. Background technique [0002] my country's meteorological satellite business is developing at a high speed. At present, meteorological satellites can be used to carry out disastrous and high-impact weather such as typhoon, heavy rain, strong convection, heavy fog, dust, and haze, as well as flooded water bodies, forest and grassland fires, high temperature and Monitoring of surface environment such as drought. Satellite ecological remote sensing services play a prominent role in the construction of ecological civilization. [0003] In traditional data retrieval, people usually retrieve data actively, but the purpose of searching for many users in life is not clear. In recent years, with the advancement of artificial intelligence and the rise of recommendation systems, more and more s...
