【摘要】The unified multimedia query language (UMQL) is a powerful general-purpose multimedia query language, and it is very suitable for multimedia information retrieval. The paper proposes a grammar analysis model to implement an effective grammatical processing for the language. It separates the grammar analysis of a UMQL query specification into two phases: syntactic analysis and semantic analysis, and then respectively uses Backus-Naur form (EBNF) and logical algebra to specify both restrictive grammar rules. As a result, the model can present error guiding information for a query specification which owns incorrect grammar. The model not only suits well the processing of UMQL queries, but also has a guiding significance for other projects concerning query processings of descriptive query languages. 【总页数】6页(317-322) 【关键词】
