Next-generation consumer innovation search: Identifying early-stage need-solution pairs on the web
展示如何利用机器学习方法从网络文本中自动识别早期用户创新的需求-解决方案对，并通过案例验证其实用价值，对市场研究人员和产品开发者有参考意义。
All innovations consist of a need paired with a responsive solution - a need-solution pair (von Hippel and von Krogh 2016). Today, technical advances in machine learning techniques for natural language understanding, such as semantic word space models and semantic network analytics, have made it practical to capture descriptions of early-stage, need-solution pairs mentioned anywhere in the open, textual content of the Internet. Producers - and anyone - can now thus look for user innovations posted on the web that may involve either known or newly defined needs coupled to new solutions that are gaining traction. This is important because, as is now understood, users, rather than producers, tend to pioneer functionally new products and services for which both the need and the solution may be novel. In this paper, we demonstrate via a case study both the practicality and the value of searching for early-stage need-solution pairs via machine learning methods and assessing the likely general interest in each usergenerated innovation by also identifying the trends in posting and query frequencies related to it. The new need-solution pair search method we describe and test here can, we claim, serve as a very valuable complement to traditional market research techniques and practices.
