摘要

[目的/意义] 专利是技术情报最可靠的来源之一，专利分析可以实现专利信息的挖掘和利用，辅助专利技术创新。技术演化分析是指技术主题产生、发展、转移和变化乃至湮灭的过程，如何对专利技术信息进行深度揭示是当前专利技术演化分析的研究重点，其关键在于技术要素信息的揭示。[方法/过程] 通过典型专利剖析、特征识别构建技术要素识别框架，提出面向特定领域的基于专利文献的技术要素识别方法。[结果/结论] 将提出的技术要素识别方法应用于纳米肥料领域，通过典型专利剖析确定5种技术要素：材料、产品、方法、功效和用途，并基于SAO结构及领域词表完成技术要素的识别。该方法能为技术演化分析奠定基础，能够从多角度展示领域技术信息。

Abstract

[Purpose/significance] Patent is one of the most reliable sources of technical intelligence. By patent analysis, one can realize the mining and the utilization of patent information, and the technology innovation. Technological evolution analysis refers to the process of emergence, development, transfer, change and even annihilation of technology themes. The focus of the current research is to deeply reveal the patent technology information, technical elements are the key to deeply reveal patent technology information.[Method/process] Proposing a method for identifying technical elements based on patent documents for specific fields by analyzing typical patents and feature recognition.[Result/conclusion] Applying our methods to the nano fertilizer field, through the analysis of typical patents, five technical elements are identified:materials, products, methods, functions and usage, and the identification of technical elements is completed based on SAO structure and domain vocabulary. Our methods can serve as a foundation for technological evolution analysis, and display field technical information from multiple perspectives.

Key words： technological evolution; technological elements; SAO structure; nano fertilizer; technological network
