In order to support inspiration of potential technical solutions, this paper considers visualization of solving means varied in patent documents through SOM. Non-structured patent document data can be quantified through two different scheme: word level co-occurrence probability vectors and correlation coefficients of the generated co-occurrence probability vectors. Comparing the two SOMs derived with the above schemes is useful for supporting innovation acceleration through extraction of important pairs of related factors in new technology development. In this paper, co-cluster structures are utilized for emphasizing field-related solutions by constructing multiple SOMs after co-clustering. Document × keyword co-occurrence analysis achieves extraction of co-clusters consisting of mutually related pairs in particular fields. Additionally, this paper also considers an extension to a multi-view situation, where each patent is characterized by additional patent classification system of F-term by Japan Patent Office. Through multi-view co-clustering among documents × keywords × F-terms, theme field-related knowledge is demonstrated to be extracted.
