摘要

在技术供需文本匹配视角下，提出了一种基于语义相似聚类的技术需求识别模型.首先，采集网络中技术需求文本提取关键短语；然后，建立领域专利技术转让索引库，基于需求关键短语检索出高相关专利，构建专利技术供给背景库，并对背景库中专利标题与摘要进行分词；第三，提出基于词向量的供需文本语义匹配度算法，筛选有效技术需求并进行语义相似聚类；最后，考虑技术需求对应的需求量和专利技术转让量，对聚类结果进行二维分类.以新能源领域为例进行实证，识别出有效技术需求195个，基于语义相似聚成12类，结合需求量与专利转让量，将12类技术需求分为“高需求、高转让”、“高需求、低转让”、“低需求、高转让”、“低需求、低转让”四大类.该研究为网络技术需求挖掘及供需匹配提供一种新思路.

Abstract

This paper proposes a technology demand recognition model based on semantic similarity and patent transaction in the view of technology supply and demand text matching. Firstly, we collect the network technology demand text and extract the key phrases. On this basis, we build the patent transaction index library, retrieve the high-related patents based on the key phrases, build background library of patent technology supply and cut the patent title and abstract those in the background library. Thirdly, we propose the method of semantic matching weight calculation of technical supply and demand text based on word vector, filter the effective technology demand and classification. Finally, we classify the clustering results in two dimensions based on the amount of demand and the corresponding amount of patent transaction. By selecting the new energy technology field as an example to test the model, it is found that there are 195 effective technology demands, they are aggregated into 12 categories based on semantic similar. Combined with the amount of demand and the corresponding amount of patent transaction, the 12 categories of technology demand are divided into four categories:“high demand, high transaction”,“high demand, low transaction”,“low demand, low transaction”,“low demand, low transaction”. The research provides a new idea for mining network technology demand and matching the demand and supply.
