Problems solved by technology

That is, the resource-scarce language not only has few resources, but also the information processing technology (such as keyword extraction, machine translation, information retrieval technology, etc.) of the resource-scarce language makes the method of constructing a comparable corpus of the resource-rich language usually not suitable for the construction of the comparable corpus of the resource-scarce language.

Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the drawings and embodiments of the embodiments of the present invention.

[0046] figure 1A schematic flowchart of a method for constructing a comparable corpus of a resource-scarce language based on pictures provided by the embodiment of the present invention, as shown in figure 1 As stated, the method includes:

[0047] S110. Download a webpage in a resource-scarce language and use it as a text in a resource-scarce language, where the webpage includes pictures in the text.

[0048] S120. Search for a webpage in a resource-rich language that contains the same or similar picture as the resource-scarce language text, as the resource-rich language text.

[0049] Figure 2 is an example of multilingual texts of the same topic based on im...

Abstract

The invention relates to a method and a system for constructing resource scarcity language comparable corpora on the basis of pictures. The method includes steps of S110, downloading resource scarcity language web pages and utilizing the resource scarcity language web pages as resource scarcity language texts; S120, searching resource abundance language web pages with pictures identical or similar to pictures of the resource scarcity language texts and utilizing the resource abundance language web pages as resource abundance language texts; S130, extracting features of the resource scarcity language web pages and the resource abundance language web pages; S140, computing similarity values of the resource scarcity language web pages and the resource abundance language web pages with the identical or similar pictures on the basis of the features; S150, selecting the resource abundance language texts with the highest similarity values and utilizing the selected resource abundance language texts as comparable texts for the resource scarcity language texts; S160, repeatedly carrying out the steps S120-S150 until resource abundance language comparable texts are found for all the resource scarcity language web pages. The resource scarcity language web pages comprise the pictures in texts. The method and the system have the advantages that the method and the system are free of constraints of resource scarcity language information processing technologies and resources, and the resource scarcity language cross-language comparable corpora can be quickly constructed by the aid of the method and the system at a low cost.

Description

technical field [0001] The present invention relates to the technical field of language information processing, in particular to a method and system for constructing a resource-scarce language comparable corpus based on pictures. Background technique [0002] Cross-language corpus is an important means to carry out cross-language natural language processing research. According to the difference in the degree of mutual translation of corpora, cross-language corpus can be divided into parallel corpus and comparable corpus. Parallel corpus (Parallel Corpus) is a collection of text pairs composed of source language text and translated target language text. There is a strict inter-translation relationship between the two language texts. The corpus is of high quality and is an important resource for cross-language information processing research. However, the construction of parallel corpora is difficult and costly; comparable corpora is a collection of text pairs in different lan...
