A hybrid similarity measure method for patent portfolio analysis

作者：

Highlights：

• A hybrid similarity measure method involving IPCs and text elements.

• An application that introduces fuzzy sets to transform IPCs to numeric values.

• A 3-level tree structure that arranges terms hierarchically for similarity measure.

• A study that applies similarity measure for technology mergers and acquisitions.
