First, research on the automatic classification method of patent
Study on the expression characteristics of patent text, analysis of the existing classification methods including feature selection algorithm and classification algorithm for automatic text classification. The disadvantages of patent information gain algorithm and K neighbor algorithm based on information gain algorithm for feature selection is proposed. The improved algorithm for K adjacent patent classification, on this basis, the automatic classification method for an efficient patent. Finally to test the United States Patent Classification as an example, the automatic classification method can accurately and effectively implement the patent patent text classification, and contributes to the innovation of design patent in the retrieval and analysis based on the application.
Two, research on the method of patent innovation evaluation
According to the characteristics of the knowledge contained in patents, using verbs and nouns respectively represent the principle of design knowledge and design knowledge structure. By introducing the concept of information entropy, respectively put forward quantitative evaluation method of novelty and compatibility of patent knowledge. Combined with morphological analysis method, established evaluation model of innovative combination of patent knowledge, are proposed. Knowledge innovation patent portfolio assessment process based on morphological analysis. In line with self-locking function driven by mechanism design patent evaluation as an example, affect the number of patent number and patent knowledge vocabulary for innovative assessment results were analyzed by comparative test, verify the validity of the proposed novelty and compatibility evaluation method and combination of patent knowledge innovation design method.
Three, research on knowledge acquisition method of mechanical product patent
According to the analysis of the existing mechanical product patent, patent structure knowledge extraction and representation methods of the existing problems, proposes a method for structure of knowledge for English patents, including two aspects of the relationship between technology and object extraction technology task. Put forward the role of knowledge of the structure of the graphical representation method of knowledge representation model structure, the function of patent extensible markup language the structure of XSD and the unified modeling language based on UML is established. The characteristics of patent language of mechanical products, as to using the maximum entropy model and in the field of patent glossary identification and extraction technology, composition of animal lexicon identifying core extraction technology. The relationship between verbs by establishing the function of patent structure knowledge representation model with modeling convenience and feature extraction the process of computer automatic processing. Combined with the United States patent case, expounds the effect of extract from the patent knowledge structure, write into XS D structured documents, finally converted to the process of obtaining the graphical representation of the functional structure.
Four, research on innovation design of mechanical products based on the inspiration of patent
Summary of the patent contributes to the inspiration of knowledge type, analyzes the characteristics of various types of knowledge, puts forward the regular expression and extraction method of non deterministic finite automaton patent inspiration based on knowledge and inspiration for the patent knowledge representation model is constructed with the function of patent knowledge structure. According to the invention patent authorization form the combination of patent knowledge types, systematically put forward the inspiration, has not found some new inspiration. On this basis, put forward the innovative design process of patent based on inspiration, through building the inspiration and patent knowledge as the core of the inspiration, creative design inspiration assisted designers to stimulate. The innovative design of hydraulic cylinder with self-locking function as an example, to verify the feasibility of this innovative design process and effectiveness.
Five, research on computer aided innovation system based on patent knowledge
On the basis of the research on the theory, developed by the knowledge base, patent database, computer aided innovation system based on patent knowledge rules and function modules, realizes the inspiration of innovative design process based on the knowledge of the patent. The combination of hydraulic cylinder product design, illustrates the operating interface of the system function module and operation method, preliminary verification the effectiveness of the system. The product innovation design produced by the system won the national invention patent.
