Visualization of patent claims structure to improve their readability

Readability is considered as a important element in effective communication. The patent claims are regarded as typical bad example of readability since they are written in long sentences and the structure is complex among different claims. In one patent document, the several claims contain hierarchical structure within each other. In this project, we want to improve the patent claims readability via visualizing the hierarchical structure. To do this, we reviewed the-state-of-the-art researches including text readability, patent claim readability and improve the readability via visualization techniques. After that, we propose a improved method to visualizing the hierarchical structure claims. We also design a user-driven evaluation method to measure the performance and collect the feedback from users.
