Solution Overview

Problem

Current search engine technologies have limited recognition capabilities for user intentions, relying on simple templates and resulting in a narrow recognition range and imprecise classification of user queries.

Innovation Solution

A method and apparatus for analyzing user intentions using artificial intelligence, which involves receiving a query, acquiring a keyword through a preset strategy, and determining the intention by parsing the query with a syntax tree to identify qualifiers, thereby enhancing the precision and range of intention recognition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If simple templates are used for intention recognition, then the method is simple and easy to implement, but the recognition range is small and classification precision is low

Engineering Contradiction:
Improvemethod complexityVSAvoidintention classification precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the intention recognition process into multiple stages: first extracting keywords from the query, then building a syntax tree to identify qualifiers, and finally determining the intention type based on the relationship between keywords and qualifiers. This segmentation allows the system to achieve high precision without requiring a single complex template to cover all cases.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of analysis by utilizing the syntax tree structure of queries. Instead of relying solely on template matching, the system analyzes the grammatical structure and relationships between different components of the query, adding a structural dimension to the recognition process that significantly improves precision.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If simple templates are used for intention recognition, then the implementation is straightforward, but the recognition field is limited

Engineering Contradiction:
Improvemethod complexityVSAvoidrecognition field range
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal intention recognition framework that can handle multiple types of queries across different domains. The syntax tree-based approach is domain-agnostic and can adapt to various query structures, making the system versatile while maintaining a relatively simple implementation through standardized processing steps.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adapts to different query types by constructing syntax trees that reflect the specific structure of each query. This dynamic structure building allows the system to handle diverse query patterns without requiring pre-defined templates for each scenario, thereby expanding the recognition field.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If template-based methods are used, then the system is simple to operate, but the intention analysis accuracy is insufficient

Engineering Contradiction:
Improvesystem operation easeVSAvoidintention analysis accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs self-service by automatically constructing syntax trees and identifying qualifiers without requiring manual template configuration for each query type. The algorithm autonomously analyzes the query structure and determines the appropriate intention classification, maintaining ease of operation while achieving high accuracy.

Inventive Principle:
Principle #25Self-service
