%X Extracted from unstructured text data of patent name and abstract, used the technology terms to analysis technology themes using the third generation of co-word analysis technology. Introduced equivalence index to measure the link strength of term-pairs. Grouped technology terms into several clusters named technology themes.

Taking fuel cell for example, experiment results show that the presented method can illustrate the industrial technology themes well.
