Method and device for automatically extracting bilingual dictionary from pictures

Abstract

The invention provides a method and device for automatically extracting a bilingual dictionary from pictures. The method for automatically extracting the bilingual dictionary from the pictures includes the following steps that a first language picture semantic annotation device and a second language picture semantic annotation device are used for annotating at least two pictures respectively; according to the output of the first language picture semantic annotation device and the output of the second language picture semantic annotation device, at least two bilingual sentence pairs both of which comprise first language semantic labels and second language semantic labels are generated; the EM algorithm is adopted for carrying out word aligning on the generated bilingual sentence pairs and entries of the bilingual dictionary are extracted. According to the method and device for automatically extracting the bilingual dictionary from the pictures, at least two bilingual sentence pairs are generated, the EM algorithm is adopted for carrying out word aligning on the bilingual sentence pairs, and therefore the entries of the bilingual dictionary can be automatically extracted from the pictures. Thus, dependence on a bilingual text and webpage resources is not needed and the method for automatically extracting the bilingual dictionary from the pictures is easy to achieve and high in accuracy.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for automatically extracting bilingual dictionaries from pictures. Background technique [0002] The development of Internet technology has broadened our knowledge and acquired more and more knowledge. However, problems also follow. Some networks only have detailed materials in English or other foreign languages, but not Chinese materials that we are familiar with, which brings great inconvenience to our work and life.
