The invention provides a webpage clustering method based on node property label propagation, which comprises the following steps: structuring a topological structure diagram model according to the link relationship of the webpage; building property feature vector for each node in the diagram model; initializing node labels in the network; iteratively updating the node labels according to the topological structure and the node property; and defining the condition of stopping updating the node labels. With the method, effective and high-quality webpage clustering can be realized within the nearly linear time only by extracting the topological relationship of the internet and the property information marking webpage characteristics without knowing priori knowledge such as the quantity and the scale of webpage groups and the like or predefining parameters such as the critical value and the like. The algorithm is simple in concept, easy to understand and realize and lower in time complexity, and can generate high-quality network clustering result, so as to apply to large-scale internet.
