Abstract: The present disclosure relates to an information obtaining method and apparatus, a device, and a medium. The method includes setting a label table corresponding to each sample sentence in a sample set, wherein row characters and column characters in the label table are set identically in accordance with an order of characters of the corresponding sample sentence; and marking cells composed of the row characters and the column characters in the label table with corresponding information category labels; taking each sample sentence in the sample set as input information to a model to be trained and the label table corresponding to each sample sentence as output information of the model to be trained, and performing model training according to a preset target function; and generating an information extraction model based on parameters of the trained model to extract target sentence information by the information extraction model.

Abstract: A text chain generation method includes selecting a to-be-matched phrase chain from a phrase chain set to match the initial phrase chain and determining the largest common subsequence between the to-be-matched phrase chain and the initial phrase chain; updating the initial phrase chain by adding a word from the to-be-matched phrase chain and other than the largest common subsequence into the initial phrase chain; using the updated initial phrase chain as a new initial phrase chain and repeating the previous steps until traversing all phrase chains in the phrase chain set to obtain an updated phrase chain; and connecting a left node located in each branch of the updated phrase chain and not connected to any node to a preset common start node and connecting a right node located in each branch of the updated phrase chain and not connected to any node to a preset common end node.

Abstract: Provided are an advertisement title rewriting method, apparatus and device and a storage medium. The method includes steps described below. Preset information in an advertisement title is replaced with a corresponding placeholder so that the advertisement title is converted into a title template; a rewritten title template is generated through a preset neural network model according to the title template, an advertisement attribute key-value table and a query cluster; and the placeholder in the rewritten title template is replaced with the corresponding preset information so that the rewritten title template is converted into a rewritten title.
