Embodiment 1
[0072] The database used by the healthy diet knowledge network in this embodiment is the NoSQL map database Neo4J. Compared with the relational database used in the traditional knowledge base, the map database can store entities and the relationship between entities in a richer form, and at the same time provide more It is a convenient and fast query method.
[0073] Such as figure 1 As shown, the present embodiment provides a method for constructing a health knowledge network based on a neural network and a map structure, and the method includes the following steps:
[0074] (1) Carry out word vector modeling on all text corpus participating in learning and training
[0075] The "word vector" in this embodiment refers to the neural network word embedding modeling algorithm and its supporting modeling tool word2vec proposed by Google in 2013. Physique Description These text corpora are input into the word vector tool word2vec, and the word vector modeling is performed on it....
Embodiment 2
[0116] This embodiment is a specific application example, which is called by relevant researchers and application developers in the form of middleware, and is composed of the following components: 1) Graph database maintenance component P01, including querying the graph database, adding and deleting nodes and edges , security backup and other functions; 2) word vector operation component P02; 3) association detection and representation component P03; 4) neural network relationship classification component P04; 5) auxiliary function component P05, including text preprocessing, text original data management, stage Functions such as result cache management. The overall architecture of the method described in the invention is as follows Figure 6 As shown, the specific functions and usage techniques of each component are shown in Table 1 below.
