Abstract: Disclosed are a method and an apparatus for constructing a binary feature dictionary. The method may include: extracting binary features from a corpus; calculating a preset statistic of each binary feature; and selecting a preset number of binary features in sequence according to the preset statistic to constitute the binary feature dictionary.

Abstract: This disclosure discloses an artificial intelligence based method and apparatus for checking a text. An embodiment of the method comprises: lexing a first to-be-checked text and a second to-be-checked text respectively, determining word vectors of the lexed words to generate a first word vector sequence and a second word vector sequence; inputting the first word vector sequence and the second word vector sequence respectively into a pre-trained convolutional neural network containing at least one multi-scale convolutional layer, identifying vector sequences in a plurality of vector sequences outputted by a last multi-scale convolutional layer as eigenvector sequences, to obtain eigenvector sequence groups respectively corresponding to the texts; combining eigenvector sequences in each eigenvector sequence group to generate a combined eigenvector sequence; and analyzing the generated combined eigenvector sequences to determine whether the first text and the second text pass a similarity check.

Abstract: Embodiments of the disclosure disclose a method, apparatus, device, and storage medium for establishing an error correction model based on an error correction platform. The method comprises: determining a target error correction level based on an error correction need of a user; and selecting at least one error correction module from each of at least two error correcting portions of the error correction platform based on the target error correction level, and combining the selected error correction module to form an error correction model.

Abstract: The disclosure discloses a search method and apparatus based on artificial intelligence. An embodiment of the method includes: receiving search information entered by a user; determining a candidate to-be-pushed message set based on the search information; predicting a probability of being clicked for a candidate to-be-pushed message in the candidate to-be-pushed message set using a pre-trained scoring model based on the search information and the candidate to-be-pushed message set, the scoring model being obtained by training based on a pre-stored first search information set, a to-be-pushed message set corresponding to a piece of first search information in the first search information set, and a preset priority of a to-be-pushed message in the to-be-pushed message set; and selecting a preset number of the candidate to-be-pushed messages to form a message sequence in descending order of the probability of being clicked, and pushing the message sequence to a terminal of the user.
