Abstract： [Purpose/significance] This paper aims to extract the tacit knowledge from the massive literatures by constructing a two-mode complex network model. [Method/process] Through the NetworkX complex network toolkit, a two-mode complex network model was constructed based on the co-occurrence relationship of any two nodes. The direct relationship between nodes and nodes was extracted by weighting the co-occurrence relationship of nodes in the network model, calculating the topology information of the network and AP clustering. The most appropriate prediction algorithm was selected by using AUC method to evaluate the four link prediction algorithms, such as AA, JC, wAA and wJC. The tacit knowledge was predicted by the most appropriate prediction algorithm from the complex networks. [Result/conclusion] The results showed that the wAA link prediction algorithm was the optimal link prediction algorithm. The two mode complex network model, indicators and method system were effective in drug target mining in the Chemical Abstracts Service database. The next step is to try in other databases or other research fields to further verify the generality and effectiveness of the model.

Abstract： [Purpose/significance] This paper try to propose a scientific, effective and reusable method to identify key technologies based on the perspective of intelligence research. It aims to provide information support for nation, regions, enterprises and innovative institutions to discover, deploy and promote the prospective R&D of key technologies.[Method/process] Based on the definition of key technology and its types, this paper used K-means++ algorithm to cluster scientific papers to identify hotspot technologies. Then it used the hotspot technologies as nodes to construct and visualize complex network through secondary clustering and Gephi. Structural holes theory was adopted to analysis the network and attributes of nodes, and thereby selected generic technologies. Link prediction algorithm was used to predict the missing edges in the network according to the structure, and we can identify the potential emerging technologies based on the phenomenon of cross-fusion of hot technologies to promote the formation of innovative technologies.[Result/conclusion] Taking the Intelligent Manufacturing as an example to carry out empirical research on the method, and validated the operability and effectiveness of the method through national authoritative documents and literature research.

Abstract： [Purpose/significance] In order to meet the needs of classifying massive patent automatically in current patent examination and patent information analysis work, this paper studies a series of patent automatic classification methods based on deep learning and compares the classification effects. This will promote the efficiency and effectiveness of patent classification. [Method/process] Aiming at the shortcoming of traditional machine learning methods, 7 deep learning models was designed, including Word2Vec+TextCNN, Word2Vec+GRU, Word2Vec+BiGRU, Word2Vec+ BiGRU+TextCNN and so on. These models based on the deep learning technology, such as Word2Vec, CNN, RNN, Attention mechanism and so on and considered the characteristics of patent text word order, context features and other key features in classification. Selecting the ‘Section’ of main International Patent Classification (IPC) was as the class labels, the study classified the Chinese patents by above 7 deep learning models and 3 traditional machine learning methods. And there was a comparison about the effect of classification in different models. [Result/conclusion] The empirical research indicated that it reached the better effect of Chinese patent classification by using deep learning methods which considered the characteristics of patent text word order, context features and other key features in classification.
