XML database full text retrieval method supporting multiple languages

Abstract

The invention provides an XML (Extensive Makeup Language) database full text retrieval method supporting multiple languages. The technical scheme of the XML database full text retrieval method can enable an XML database management system not to depend on language option settings any more, and supports the full text retrieval by using query condition character strings formed by a plurality of the languages in the same text matching condition; and a plurality of languages and words can also be contained inside an XML document that is retrieved at the same time. The technical scheme of the XML database full text retrieval method is of greatly practical value to the full text retrieval of a great number of multi-language texts under the internationalization flood tide based on an Internet because such text contents and full text retrieval requirements increase unceasingly and quickly; and the full text retrieval limited to a single language cannot satisfy the requirements, and only the XML database management system supporting the multi-language full text retrieval is of practical value. Particularly, the function is more useful in Chinese user groups, and the XML database full text retrieval method can adapt to the retrieval requirements and the present situation that the current Chinese texts contain a great number of English words.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a full-text search method for an XML database supporting multiple languages. Background technique [0002] XML (full name Extensible Markup Language) is a markup language specially designed for the Internet, and because of its ability to effectively express various information and data and make various applications work together, it has become a data publishing and data processing language. The de facto standard for exchange, XML has therefore been developed and widely used in recent years. The focus of XML is not on the form of data itself, but on the management of data information. Therefore, XML makes it possible to unify different database modes and provides a way for the integration of heterogeneous databases. [0003] XML database management system (XML database management system) is a new type of database management system (database management system) that has developed...

AI Technical Summary

Problems solved by technology

If an XML database management system can only retrieve texts limited to a certain language, it cannot meet the full-text retrieval requirements of such multilingual texts, especially the needs of Chinese users

Moreover, there are certain technical difficulties in realizing full-text retrieval in multiple languages, which hinders the development of full-text retrieval technology in XML database management systems.
