Embodiment approach 2

[0053] Obtain the claims and abstracts of all public patents and invalid patents of 7 key enterprises in 2016, use the LDA model to calculate the topic probability, add the corresponding probabilities of all patents involved in the same technical topic, and obtain the total value of each technical topic, and extract the maximum and minimum values. Calculate the new application correlation degree and new invalidation correlation degree of each technical theme separately from the data and establish a two-dimensional coordinate system. The scatter distribution of each technical theme of the seven companies is as follows: Figure 4 shown. Most of the technical themes gather in areas with low new application correlation and low new failure correlation. When the new application correlation and new failure correlation exceed a certain value, the distribution of technical topics shows a trend of dispersion. Figure 4 The figure shows that each company's technology theme distribution ...

Abstract

This application provides a method for identifying research and development directions, including: Step 1: Collect patent documents, divide patent documents into three parts: new application documents, new invalidation documents, and other documents, and integrate new application documents and new invalidation documents as an analysis database ; Step 2: Generate technical topics and establish a topic matrix; Step 3: Calculate the new application correlation and new failure correlation of the topic matrix; Step 4: Identify the research and development direction. Using the method of the present invention, rules can be established to identify four types of research and development status, analyze technology research and development trends, and provide references for the unit's technology research and development dynamics and adjustment of research and development strategies.

Description

technical field [0001] The present invention relates to the technical field of big data, and more specifically, relates to a method for identifying research and development directions. Background technique [0002] With the rapid growth of the number of patent documents, unit analysis research based on patent data is becoming more and more common. The research work can be divided into two categories, one is unit identification, and the other is the analysis of specific units and the acquisition and analysis of competitive intelligence. [0003] In the patent citation analysis method, the highly cited analysis method is mainly used to identify units. In 2003, Batagelj (2003) proposed the critical path method based on Dosi's (1988) main path theory of technological evolution. However, the critical path method and the highly cited analysis method can only identify important units, and cannot determine the competitive position of the units. Kim et al. (2011) believed that whe...
