“…Second, we use the second method proposed in section 3.3.1 to obtain neighbors, and use the first method proposed in section 3.3.2 to give the neighbors an initial weight. Using the attribute information of the target item to obtain its neighbor items, the target user lacks the attribute information, so the neighbor users of the target user are obtained according to the method of part (2) of section 3.3.1; The initial weight of the neighbor item is given according to the attribute similarity of the item, and the initial user is given an initial weight according to (9). The experimental selection recommendation list is Top-5, and the abscissa is the similarity threshold .…”

“…We use the second method proposed in section 3.3.1 to obtain neighbors, and use the second method proposed in section 3.3.2 to give the neighbors an initial weight. We give the neighboring item an initial weight according to the importance of the item node mentioned in part (2) of section 3.3.2 and give the neighboring users an initial weight according to (9). The abscissa is the length of the tag recommendation list, and the ordinate is the F1 value.…”

“…However, few existing models exhibit this characteristic. ey assume that the rumor propagation rate is a constant throughout the whole propagation process, which ignores the potential influence of ignorant's neighbors [24] on the ignorant when the ignorant turns into a spreader. ere is also such a social phenomenon, that is, the attitude of individuals towards rumor would change due to the perception from life.…”

“…In this case, more people, especially leader spreaders with strong influence on individuals, understand the original meaning of the matter, which can control the disturbance to the public order. Hence, combining with different circumstances in real life, 3‐5 the establishment of appropriate propagation model can provide relevant managers with evidence for working out methods to control information propagation.…”
