Embodiment Construction

[0045] The present invention is further described below by way of embodiment and accompanying drawing.

[0046] Preprocessing and Parameter Estimation

[0047] The overall process of the present invention is to input Chinese unregistered words as a query into Google A search engine that returns a summary set of search results and extracts translation candidates from the summary set. At the same time, some heuristic rules and information entropy combined with partial features are used to filter the noise for initial sorting, and the top few are taken as the final translation candidates. Then, the features of translation candidates are extracted, and SVM and Ranking SVM are used to evaluate the correlation between translation candidates and unregistered words. In the above process, it is necessary to preprocess the returned abstract set, that is, set the search engine to return English web pages in the Chinese-English translation of unregistered words; remove hyperlinks, et...

Abstract

The invention belongs to the technical field of multimedia information processing, specifically relating to a Chinese-English unknown words translating method blending Web excavation, multi-feature and supervised learning. The method provided by the invention comprises four steps as follows: pre-processing and estimating parameters; acquiring translation candidates based on Web; representing the translation candidates based on multi-feature; ordering and estimating translation results. In the invention, a method for acquiring corpora through Web excavation, representing the translation candidates with multi-feature, and ordering the translation candidates through supervised learning. Compared with the traditional method, the method provided by the invention has the advantages of simple corpora acquiring method and pre-processing, overall features for representing the translation candidates, and high accuracy for translation results. Unknown words translation is one of important and difficult points for text processing; the effective Chinese-English unknown words translating method is provided by the invention, so that the method has the important application value in machine translation and cross-language information retrieval fields.

Description

technical field [0001] The invention belongs to the technical field of multimedia information processing, and in particular relates to a method for translating Chinese-English unregistered words. Background technique [0002] With the rapid development of social informatization and the Internet, new words, terms, popular terms, etc. appear on the Internet in an endless stream. The number of these new named entities is huge and constantly updated, and they cannot be found one by one in the existing bilingual dictionaries. Unregistered words of . The translation of unregistered words refers to inputting unregistered words in the source language and outputting their translation in the target language. With the continuous development of Machine Translation (Machine Translation) and Cross-language Information Retrieval (Cross-language Information Retrieval, CLIR), it is extremely important to be able to quickly and accurately translate unregistered words. It is one of the impor...
