Problems solved by technology

[0026] Finally, in conventional relational or object-relational databases, it is never possible for a user lacking programming skills to formulate complex database queries and must rely on programs written by programmers to search and display data
so the user's options are often very limited

Embodiment Construction

[0055] The following sections describe structured natural language query and knowledge systems, an improved object-relative query language, and object-relative algebra, which illustrate various inventive features. As will be appreciated, many of these features can be implemented in a given system without requiring other systems. For example, a structured natural language query system can be implemented in conjunction with a general data platform without the need for a modified object-relative query language or object-relative algebra. Furthermore, various inventive features may be implemented in ways other than those described herein. As such, the following description is intended to illustrate and not to limit the scope of the invention.

Abstract

The invention relates to a structured natural language query and knowledge system, which allows a user lack of programming experience to input database for query or input rules in the form of structured language sentences. The range of the sentences is defined by improved object-related query languages for preference, object-related algebra, or both the object-related query languages and the object-related algebra. Conditions which appear in the form of the natural language are defined by corresponding form query texts, the user is prompted to use defined instructions and conditions for arranging and structuring natural language sentences, the instructions selected by the user and the parameters thereof are used as verb phrases of structured natural language sentences to appear, and the conditions selected by the user and the parameters thereof are used as adjective phrases to appear. The sentences are divided and changed to query texts in the form of translation used for database query and rule treatment.

Description

technical field [0001] The invention relates to the field of object-oriented and object-related databases, in particular to structured natural language database query and knowledge systems. Background technique [0002] Relational databases have been widely used for many years. A relational database arranges data in tables containing fields. Two tables containing the same fields are related to each other. Compared with the "flat file" method (which stores all data in a single file), the method of relating tables is more malleable. [0003] Most relational database systems follow the Structured Query Language (SQL) standard. Commercial vendors produce SQL-based database systems such as Oracle, Sybase, Informix, Progress, and Microsoft Access. These systems use the SQL formal query language. Here is an example of a formal query to display the names and salaries of employees whose salary exceeds $100,000: [0004] For each employee where employee.salary>100000: [0005]...
