5 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.

The application discloses a quick disambiguation reconstruction correction method of a pinyin input method, and realizes continuous, local and structured reconstruction of an input stream in a pinyin input process by introducing a syllable sequence cache, local window processing, candidate reconstruction and mapping replacement mechanism, and significantly improves input efficiency.

This invention discloses a method for Chinese character input combining eye-tracking and P300 technology. The method utilizes the spatial modulation information of the eye-tracking device to select a mode: the eye-tracking device collects the user's visual trajectory in real time, obtaining the coordinates of the user's eye movement points. When the user gazes at the start option, the system detects this intention and generates a command to activate the spelling process. Combining the eye-tracking device and P300 technology, the initials and finals of the Chinese characters are selected. The method then integrates with a Pinyin input method to achieve the function of inputting Chinese characters: after selecting the initials and finals, the user switches to the Pinyin input method, selects the target Chinese character, and thus achieves the Chinese character input function. This invention, combining eye-tracking and P300 technology for Chinese character input, allows users to achieve computer typing functions without taking any action, relying solely on their eyes and brain. Furthermore, the use of a standard Chinese input method's character library enables matching Chinese characters after spelling. This expands the scope of assistive devices for people with movement disorders beyond computer devices themselves, and has significant practical implications.

The invention discloses a 15-key Chinese character coding method and key layout, and relates to the field of input methods, a three-row five-column key layout is adopted, and each key corresponds to two keys of a computer keyboard. The Chinese character coding method comprises the following steps of: distributing four parts of five, three and two strokes, etymons, initial consonants and finals in 15 keys according to a certain rule, and combining corresponding key characters according to a certain rule to form Chinese character codes. According to the Chinese character coding method, the longest single character is five codes, and the longest word is six codes. The concept of five, three and two strokes is put forward for the first time. Due to the fact that the input method is in a 15-key layout, compared with a 26-key input method, the input method is more suitable for small-screen equipment such as mobile phones. According to the method, the advantages of a shape code input method, a binary syllabification input method and a two-stroke input method are combined, and a novel Chinese character coding method which is easy to learn and remember, low in repeated code rate and high in input efficiency is formed.

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.
