Abstract: According to embodiments of the present disclosure, a method and apparatus for rewriting a narrative text, a device, and a medium are provided. The method includes determining a change to a sentence in a narrative text. An initial context of the sentence before the change is different from a target context of a changed sentence. The method further includes performing, based on inconsistency between a text part after the sentence in the narrative text and the target context, at least one edit operation on the text part to generate at least one edited version of the text part. The method further includes replacing the text part with an edited version in the at least one edited version to obtain a rewritten narrative text. In this way, the narrative text can be rewritten with a small number of edits while ensuring contextual coherence.

Abstract: Implementations of the present disclosure relate to methods, devices, and computer program products for generating a destination vocabulary from a source vocabulary. In a method, a group of candidate vocabularies are determined from the source vocabulary based on a corpus, a size of a candidate vocabulary in the group of candidate vocabularies being different from a size of the source vocabulary. A group of marginal scores are obtained for the group of candidate vocabularies, respectively, a marginal score in the group of marginal scores being obtained for the candidate vocabulary based on a corpus entropy of the candidate vocabulary and a size of the candidate vocabulary. The destination vocabulary is selected from the group of candidate vocabularies based on the group of marginal scores.

Abstract: A trencher includes a trencher body; a cable detection mechanism disposed at a front portion of the trencher body; a chain mechanism and a jet mechanism disposed in the center of a bottom portion of the trencher body; a first track mechanism and a second track mechanism, the first track mechanism being disposed on a first side of the bottom portion of the trencher body, and the second track mechanism being disposed on a second side of the bottom portion of the trencher body; and a soil discharging component disposed at a rear portion of the trencher body.
