Method for constructing aspect-level sentiment analysis model based on graph attention network

The invention provides a method for constructing an aspect-level sentiment analysis model based on a graph attention network. According to the method, modeling is carried out on syntactic features of a text, an effective syntactic dependency relationship between aspect words and viewpoint words is obtained, and then more appropriate representation used for aspect-level sentiment analysis is obtained. According to the method, the original syntactic dependency tree is pruned, so that the negative influence of redundant information on emotion polarity judgment in the target aspect is avoided. Irregular syntactic structure information is processed in combination with a graph attention network, and syntactic information in a long-distance range can be better captured without purely using an attention mechanism and a model of a convolutional neural network.

E-mail gateway type systematic mail account maintaining method

The invention provides a method for maintaining the e-mail accounts in systems such as an e-mail gateway and the like. The method detects the mail account information by using a POP3 protocol and an SMTP protocol, then stores the valid account information in a dynamic hash table, and maintains the validity of the information by a time sliding window, therefore, when mail delivery fails, the mail is discarded from the hash table, and the new accounts are detected after the waiting period of the sliding window. The hash structure is stored in a file system in a fixed period to avoid information loss and realize direct loading from the file system when accidental restart occurs. The advantages of the method includes: 1) the method can help to reduce the load on the gateway and improve the utilization rate of the gateway system by assisting to filter a large amount of invalid mail information; and 2) the method cuts down the deployment costs of the system by supporting the simultaneous management ...
