AI Technical Summary

Technical Problem

The existing psychological evaluation method based on large language models is lost when processing long texts and multiple rounds of conversations, and the adversarial samples are insufficiently robust, resource requirements are high, making it difficult to effectively apply in resource-limited environments.

Method used

A psychological evaluation method based on the large language model Agent is proposed, including the user psychological feature extraction module, the user psychological state search module, the agent questioning module and the psychological evaluation report generation module. Through multiple large language models loading specific prompt words and connecting them through thinking chains, maintaining context consistency; introducing knowledge graphs and vector knowledge bases to improve the robustness of the adversarial samples, and optimizing resource utilization through modular design.

Benefits of technology

It enhances context retention capabilities, improves the robustness of the countermeasures, reduces resource requirements, realizes personalized and precise psychological assessments, and improves the effectiveness of user experience and evaluation results.

Abstract

The invention belongs to artificial intelligence, and relates to a psychological assessment method based on a large language model Agent, which comprises the following steps of: extracting user-level cue words from each round of dialogue with a user by utilizing a user psychological feature extraction module, connecting the user-level cue words with system-level cue words obtained when a large language model is loaded, performing entity recognition on the cue words spliced together through a large language model; matching the extracted entity nodes with symptom nodes in the psychological state knowledge graph by utilizing a user psychological state retrieval module, and retrieving all corresponding psychological state node sets; the Agent questioning module is used for initiating questioning according to the answer of the user; according to the psychological assessment report generation module, the large language model searches a self-scale with the highest similarity with the user state according to all features extracted by dialogue with the user, and sends a report with the highest similarity with the condition that the user completes the self-scale to the user; the use experience of the user and the effectiveness of the evaluation result are improved.
