Problems solved by technology

But in fact, except for a very few special users who have IT foundation or are very interested in IT, this method is impossible for most users to accept
General business personnel only want to focus on their own profession, rather than complex IT technology. Unless a simple and efficient data search tool such as Baidu search is provided, it is more difficult to extract data from the database

Embodiment Construction

[0051] Such as figure 1 As shown, a method and system for searching relational complex management information system data in natural language, the specific implementation part introduces the system from two levels of system function points and feature points included in the function points, and the logical process of implementation can be seen figure 1 Logic flow chart. The system consists of the following parts:

[0052] 1. Natural language analysis module:

[0053] According to the semantic analysis table, see Table 1-1, this module can perform semantic analysis on the search conditions input by the user, identify the table name, attribute name and attribute value in the input conditions, and match the attributes and attribute values ​​according to the rules. In order to facilitate the next generation of query statements to execute the query. There are three main features in this step:

[0054] 1.1. Part of speech analysis module:

[0055] According to the "Identificati...

Abstract

The invention discloses a method and a system for searching relational complex management information system data in a natural language. The system comprises a natural language analysis module which carries out semantic analysis on search conditions input by a user according to a semantic analysis table, recognizes table names, attribute names and attribute values in the input conditions respectively, matches the attribute names and the attribute values according to rules, and completes logic recognition and combination of multiple conditions according to a matching result and set rules; a data query module which is used for processing the data analysis result according to the single-table association search logic and the hierarchical search logic, converting the processed query conditioninto an SQL query statement to execute query, and submitting the query result to the data security control module; a data security control module which realizes two levels of authority control; And asearch result display module which is used for submitting the data information to a user in the form of service information rather than pure form data. According to the system, the data availabilityis improved, and meanwhile, the data utilization rate is also increased.

Description

technical field [0001] The invention relates to the technical field of management information systems, in particular to a method and system for searching relational complex management information system data in natural language. Background technique [0002] In the existing technology, many organizations are running ERP and other complex management information systems based on relational databases. Most users of such systems are management-oriented, and data statistics and analysis are one of the core daily tasks. Therefore, the availability of data is a concern of such users. [0003] The reality is that most users of MIS are very passive in acquiring data, often requiring the assistance of developers and hardly autonomous. This greatly affects the value of data and reduces the work efficiency of business personnel. If you want business personnel to be able to independently obtain the data stored in the database, one way is to let users learn and let them know the databas...
