Starting from Patents to Find Inputs to the Problem Graph Model of IDM-TRIZ

TRIZ theory is primarily based on patent's observation and one of its extensions for complex situations is known as Inventive Design Method (IDM). This paper proposes a new approach of automatic retrieval of IDM concepts from patents. It mainly consists of using generic linguistic markers to locate and extract IDM related knowledge, such as problems, partial solutions and parameters, to automatically populate IDM Ontology. Lastly, a comparison is made between respective results of manual and automatic retrieval to assess the current accuracy of our approach.
