3 results about "Pinyin input method" patented technology

The present application relates to the technical field of information security, in particular to a Chinese character encryption and decryption method and device based on nine-square grid pinyin; the present application uses nine-square grid pinyin input method to correspond any encryption symbol with nine-square grid; when plaintext is sent by spelling pinyin, the output is the position and order of each time pressing the corresponding nine-square grid; the encryption symbol on the corresponding nine-square grid is matched according to the position and order of the corresponding nine-square grid; the pinyin of the plaintext is separated according to single Chinese character or word by combining the separation bit, and the ciphertext is formed; when the private key is known by both the sending and receiving parties, the corresponding pinyin and sentence content are determined according to the encryption symbol matching the letter on the corresponding character bit, combining the separation bit, and combining the meaning of the word group or the meaning of the sentence, and the decryption is realized. The whole method is based on nine-square grid pinyin, which reduces the learning cost and difficulty, and also reduces the decryption difficulty; meanwhile, the position is used for positioning, which increases the encryption type and possibility, and also increases the decryption difficulty.

This invention discloses a method for implicit sentiment recognition of Weibo text that integrates multiple features and an emoji sentiment dictionary. Belonging to the field of sentiment analysis in natural language processing, the method includes the following steps: Step 1: Data collection and processing; Step 2: Assigning corresponding sentiment intensities to default emojis in Weibo posts and establishing an emoji sentiment dictionary; Step 3: Extracting character features and phonetic features from Wubi, Zhengma, and Pinyin input methods, and fusing the extracted features; Step 4: Using a Bi-GRU network to learn deeper semantic information; Step 5: Calculating the sentiment polarity of the text and combining it with the emoji sentiment dictionary to obtain the implicit sentiment classification result. This invention integrates Chinese features to identify online words, improving the accuracy of identifying words with similar shapes and sounds, and, combined with the emoji sentiment dictionary, enhances the effectiveness of identifying implicit sentiment in Weibo text.
