Abstract: Provided are a search request processing method, an apparatus, a computer device, a storage medium, a computer product, and a computer program. The method includes: in response to a search instruction, sending a search request comprising a target question; acquiring a plurality of sets of answer information corresponding to the target question, wherein each set of answer information includes answer summary information and a multimedia content supporting the answer summary information; the genre of the multimedia content is determined on the basis of a category of the target question, and the answer summary information is extracted on the basis of the multimedia content; and displaying the answer summary information in each set of answer information on a search result page, and displaying, when any piece of answer summary information is selected, at least part of the multimedia content supporting the selected answer summary information.

Abstract: The present disclosure provides a method for preparing resorcinol through micro-channel reaction. In the method, resorcinol is prepared through micro-channel reaction using m-aminophenol as a raw material, a diazo salt is synthesized at 0° C. or more, hydrolysis of the diazo salt is performed at 90° C. or less, and then reaction conditions are reduced; the reaction time is decreased from traditional 10 hours to less than 2 minutes, and therefore the reaction time is significantly shortened; the purity of a product is 75% or more, which is significantly improved.

Abstract: Disclosed are a language representation model system, a language representation model pre-training method, a natural language processing method, an electronic device, and a storage medium. The language representation model system includes: a word granularity language representation sub-model based on segmentation in units of words, and a phrase granularity language representation sub-model based on segmentation in units of words. The word granularity language representation sub-model is configured to output, based on a sentence segmented in units of words, a first semantic vector corresponding to a semantic expressed by each segmented word in the sentence. The phrase granularity language representation sub-model is configured to output, based on the sentence segmented in units of phrases, a second semantic vector corresponding to a semantic expressed by each segmented phrase in the sentence.
