Patent documents hold valuable research but are lengthy and technical, making human analysis laborious, so automated tools are highly needed. The paper proposes text‑mining methods for patent map analysis. The authors applied these methods to a real‑world carbon‑nanotube patent map. Machine‑derived terms from patent segments match manually selected terms, indicating that future patent mapping can be performed more effectively and efficiently.
Patent documents contain important research results. However, they are lengthy and rich in technical and legal terminology such that it takes a lot of human efforts to analyze them. Automatic tools for assisting patent analysis are in great demand. This paper describes some methods for patent map analysis based on text mining techniques. We experiments on a realworld patent map created for an important technology domain: “carbon nanotube”. We show that most important category-specific terms occur in the machine-derived extracts from each patent segment and that machine-derived feature terms can be as good as those selected manually. The implications is that future patent mapping can be done in a more effective and efficient way.
