Heterogeneous information networks (e.g. bibliographic networks and social media networks) that consist of multiple interconnected objects are ubiquitous. Clustering analysis is an effective method to understand the semantic information and interpretable structure of the heterogeneous information networks, and it has attracted the attention of many researchers in recent years. However, most stu...
The inefficient utilization of ubiquitous graph data with combinatorial structures necessitates embedding methods, aiming at learning a continuous vector space for the which is amenable to be adopted in traditional machine algorithms favor representations. Graph methods build an important bridge between social network analysis and analytics as networks naturally generate unprecedented volume co...
In this study, the nano-SiO2/hexamethylenetetramine as a new basic heterogeneous nanocatalyst was prepared and used for the synthesis of pyranopyrazole via the four-component reaction. Various aldehydes, hydrazine hydrate, ethyl acetoacetate and malononitrile were reacted at room temperature under solvent-free and grinding conditions. The morphology and structure of nano-cat...
