Abstract: A method includes obtaining n pairs of translation sentences of a source language and a target language, where each of the n pairs of translation sentences includes a source language sentence and a target language sentence that are translations of each other, extracting a source language segment from each source language sentence in the n pairs of translation sentences using an extraction rule of the source language, extracting a target language segment from each target language sentence in the n pairs of translation sentences, and generating an extraction rule of the target language based on n target language segments extracted from n target language sentences.

Abstract: The method includes: obtaining n pairs of translation sentences of a source language and a target language, where each of the n pairs of translation sentences includes a source language sentence and a target language sentence that are translations of each other; extracting a source language segment from each source language sentence in the n pairs of translation sentences by using an extraction rule of the source language; extracting a target language segment from each target language sentence in the n pairs of translation sentences; and generating an extraction rule of the target language based on at least n target language segments extracted from n target language sentences. According to the solution provided in embodiments of this application, the extraction rule of the target language can be automatically generated based on the determined extraction rule of the source language.
