searching the search word in the B tree to obtain the mapping from Chinese to English vocabulary entry, wherein the step of searching the English vocabulary entry mapped correspondingly by [ vertical notation ] comprises the following steps: aspire, pupose, will.
2) And (3) searching mapping relation in the reverse full-text retrieval database:
and searching English entries mapped correspondingly by the search word [ stem ] in the B tree, wherein the corresponding entry mapping is not found.
3) Returning English vocabulary entries aspire, pupose and scroll mapped by the auxiliary database in the English-Chinese double-solution dictionary according to the weight or the vocabulary entry ordering mode.
As shown in fig. 8, when performing chinese retrieval using the english-chinese dictionary, a chinese term [ china ] is input, english entries mapped in the reverse full-text retrieval database are retrieved, english entries mapped in the auxiliary database are retrieved, weights of the respective mappings of the retrieved chinese term and english entries are calculated and superimposed on weights of the corresponding chinese term and english entries in the reverse full-text retrieval database, and the corresponding english entries are preferably returned according to the weights.
The Chinese (China) is used for mapping the English entry (China) with the highest weight, and the other English entries are returned in sequence according to the weight, including Chinese, Catay, kung fu, Chink, CN, China town and the like, and the details of the English entry are entered by clicking the corresponding English entry.
Particularly, the mapping result of the chinese language and the english language may be returned according to a weight, and may also be returned according to a plurality of sorting manners such as a vocabulary entry arrangement order.
The present invention is not only suitable for english-chinese double-solution dictionaries, but also suitable for german-chinese, japanese-chinese, russian, korean-chinese, french-chinese, western-chinese, ideographic and other double-solution dictionaries, as well as other double-solution dictionaries of languages and chinese, and will not be illustrated one by one here.
The implementation of the invention has the advantages that:
according to the technical scheme, word segmentation processing and library building are carried out by utilizing the first language paraphrases of the double-solution dictionary, one or more of a semantic knowledge base, a dictionary database and a corpus are introduced to serve as an auxiliary database to carry out mapping from the first language to the second language vocabulary entries, candidate second language vocabulary entries are output according to the weight or the vocabulary entry ordering mode, and the accuracy and the coverage degree of word selection when a user queries the double-solution dictionary by using the first language are greatly improved. When the comprehensive index database is not constructed, the mapping relation between the first language and the second language vocabulary entry in the auxiliary database is only required to be called, and the corresponding second language vocabulary entry in the double-solution dictionary is returned, so that the first language retrieval of the double-solution dictionary is realized. The first language retrieval of the double-solution dictionary is carried out by introducing one or more mapping relation databases from the first language retrieval words to the second language entries as auxiliary databases, the best entries matched when the first language in the double-solution dictionary is used as retrieval keywords are output, and the rest of mapped entries are used as candidate entries for the double-solution dictionary query of a user according to the mapping relation, so that the first language word searching user experience of the double-solution dictionary is improved.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention disclosed herein are intended to be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
