摘要
在科技资源服务交易的过程中,技术需求文本往往存在描述模糊、非结构化等问题,为应对由此引起的服务供需匹配困难的现象,开展面向科技资源服务交易的供需匹配技术研究。提出一种服务供需匹配模型,首先提取技术需求文本的关键词,接着构建技术供给核心库,采用相关模型训练词向量并计算供需文本之间的语义相似度,最后计算出二者的匹配值。对线上电子信息技术领域的供需文本进行测试,计算出给定供需文本之间的匹配值,为实现科技服务交易中的供需对接与供需匹配提供一种新思路。
In the process of science and technology resource service transaction, the description of technology demand text is often fuzzy and unstructured. In order to deal with the difficulty of service supply and demand matching caused by this, this paper studies the technology of supply and demand matching for science and technology resource service transaction. A service supplydemand matching model is proposed. Firstly, the key words of technology demand text are extracted. Then, the core database of technology supply is constructed. The relevant model is used to train the word vector and calculate the semantic similarity between the supply and demand texts. Finally, the matching value of the two is calculated. This paper tests the supply and demand texts in the field of online electronic information technology, calculates the matching value between the given supply and demand texts, and provides a new idea for the realization of supply and demand docking and supply and demand matching in science and technology service transaction.
