Semantic analysis method and device

The invention discloses a semantic analysis method and device. The method comprises the following steps of: for each sample sentence in a dialogue flow, inputting a word vector of each word in the sample sentence into an encoder model to obtain a sentence vector for expressing a semantic meaning of the sample sentence; respectively inputting the sentence vectors into a first decoder model corresponding to each context sentence of the sample sentence and a second decoder model corresponding to each word of the sample sentence so as to obtain a first identifier corresponding to the context sentence and a second identifier corresponding to the word; determining a value of a target function according probabilities of the first identifiers and probabilities of the second identifiers; carrying out parameter training on the encoder model according to the value of the target function; and inputting the word vector of each word in a test sentence into the trained encoder model so as to obtain asentence vector for expressing a semantic meaning of the test sentence. Through the method, the training time length can be shortened, the calculation efficiency can be improved, and the technical problems that the model training time is long and the semantic analysis efficiency is low in the prior art are solved.

Purification method of porcine circovirus II type virus-like particles

The invention provides a purification method of porcine circovirus II type virus-like particles. The method is a new purification method developed through experiment measures centring on the self-characteristics of the PCV2 virus-like particles and the characteristics of an expression system of the PCV2 virus-like particles. The method comprises the steps that firstly, cell lysis is achieved through comprehensive utilization of freezing-thawing and ultrasonic treatment measures; secondly, a great amount of cell debris and macromolecule impurities are removed by means of a filter plate module, and sterile supernatant liquid is obtained; thirdly, the supernatant liquid is concentrated by means of a 100kD hollow fiber membrane system, and a concentrated virus antigen solution is obtained; fourthly, chromatographic purification is conducted by means of a Sepharose 4FF molecular sieve chromatographic purification system in optimized operation conditions. The method is designed closely aiming at the characteristics of the PCV2 virus-like particles, and particularly suitable for the purification of recombinant baculovirus PCV2 virus-like particles. By means of the method, the impurities can be more efficiently removed and separated to obtain target proteins, and target antigens can be effectively recycled.
