Natural Language Interface Of Database And The Application Of The Audit

Computer-aided audit manual audit of the original change the subject and content, a new audit methods and audit mode, improve the efficiency of the audit. However, in many of the audit of the project audit specialists are experts with the close integration of the computer to complete tasks. This makes the need for a detailed understanding of computer experts digest audit specialists demand after the audit, the audit can only write on the correct database query. Based on the field of database dedicated Chinese Query Interface to good solve this problem, make an independent audit experts to the completion of the audit work on the database.In this paper, a thesis on the background and status through the existing technology base, to the database query language interface Chinese model. Achieve the Chinese query language to generate executable in the audit database of all SQL statements module design. Because the Chinese language has the semantic structure of the complex and volatile, full of ambiguities and other characteristics, and the query language content revolves around the concept of the database, through the rational design of the database query language limited Chinese grammar in meeting users on the premise of reducing system realize the complexity.Automatic phase in the use of the word improve the segmentation algorithm, based on the semantic database Disambiguation determine strategy and words. Semantic understanding of the stage through the database for Chinese objectives and conditions for a full analysis, the corresponding language for generating intermediate objective analysis algorithm and the conditions for analysis algorithm. Finally, the SQL statement generated integrity stage, a search condition and their relevance to the objectives for the analysis of the path generated by the FROM clause intermediate language completed SELECT clause and the WHERE clause generated a complete portfolio for SQL. Finally this paper, a case detailed implementation process, as well as practical applications in the system admitted to the good results.
