Embodiment Construction

[0044]As mentioned in the background art, the data storage structure of the part of speech database established in the prior art is relatively complex, and cannot meet the requirements of search (for example, there are certain keywords that cannot retrieve relevant information). The study found that the structure of the part-of-speech library is a multi-level data structure, such as: including the parent-level part-of-speech classification, the sub-level part-of-speech classification under the parent-level part-of-speech classification, and the grand-level part-of-speech classification under the sub-level part-of-speech classification. In a specific example, a part-of-speech database includes: a parent-level part-of-speech classification ( / foreign enterprise, indicating a data label), and a parent-level part-of-speech classification ( / foreign enterprise) includes two juxtaposed sub-level part-of-speech classifications ( / foreign sole proprietorship enterprise) and ( / Sino-foreign...

Abstract

The invention discloses a multistage data storage method and apparatus, a multistage data structure and an information retrieval method. The multistage data storage method comprises: storing correlative multistage data by adopting a single data classification structure. The method comprises: generating data labels of the multistage data, recording correlative relationship information corresponding to the data labels, and recording semantic content of underlying data labels, wherein the correlative relationship information is used for storing relationships between data at a current stage and data at previous and next stages; determining whether the semantic content of the data labels is recorded; and if yes, recording the semantic content of the corresponding data labels. The multistage data structure formed with the storage method is structure, and the data labels are endowed with practical semantic meanings, so that the precision and efficiency of information retrieval can be improved.

Description

technical field [0001] The invention relates to data storage technology, in particular to a multi-level data storage method and device, a multi-level data structure, and an information retrieval method. Background technique [0002] Knowledge base, also known as intelligent database or artificial intelligence database. The knowledge base is a structured, easy-to-operate, easy-to-use, comprehensively organized knowledge cluster in knowledge engineering. It is aimed at the needs of solving problems in a certain (or some) fields, and uses a certain (or several) knowledge representation methods in the computer memory. A collection of interconnected pieces of knowledge stored, organized, managed, and used in . These pieces of knowledge include domain-related theoretical knowledge, factual data, and heuristic knowledge obtained from expert experience, such as definitions, theorems, algorithms, and common sense knowledge related to a certain domain. [0003] With the application ...
