Abstract: The disclosure discloses a cyberbullying detection method and system. The detection method includes: obtaining a to-be-detected data set, where the to-be-detected data set includes multiple sentence texts of multiple users; classifying the to-be-detected data set by using a classification model based on a bidirectional recurrent neural network, to obtain a probability that each sentence text belongs to cyberbullying; obtaining a sentence text whose probability of belonging to cyberbullying is greater than a specified probability, to obtain a first sentence text set; obtaining an attention value of each sentence text in the first sentence text set and an attention value of each user; detecting, according to the attention value of each sentence text in the first sentence text set and the attention value of each user, whether each sentence text belongs to cyberbullying. The disclosure can achieve a good text classification and identification effect, high accuracy, and a low loss rate.

Abstract: A clean and rapid smelting method in an electric arc furnace with full scrap steel, is suitable for smelting process of 30-300 t electric arc furnace with full scrap steel. In the smelting process of the electric arc furnace with full scrap steel, different kinds of mediums are injected by an injection lance which is installed inside refractory material of sidewall at the bottom of the electric arc furnace in different stages of smelting. Carburization is utilized in molten pool to accelerate melting down and improve carbon content of the molten pool at the stage of recarburizing and fluxing. A reaction in the molten pool is intensified at the stage of high efficiency dephosphorization and deep denitrogenation, to enhance efficient dephosphorization and deep denitrification of the reaction in the molten pool, thereby accelerating the smelting speed of the electric arc furnace with full scrap steel, improving effect of dephosphorization and denitrification.

Abstract: A method for a state transition includes determining whether a user equipment (UE) is a UE frequently performing state transitions. When the state of the UE is required to be transitioned to the idle state, a state of the UE is transitioned to a paging channel (PCH) state if the UE is a UE frequently performing state transitions. If the UE is a UE infrequently performing state transitions, the state of the UE is transitioned to the idle state.
