Abstract: Disclosed are a Nested Named Entity Recognition method based on part-of-speech awareness, system, device and storage medium therefor. The method uses a BiLSTM model to extract a feature of text word data in order to obtain a text word depth feature, and each text word of text to be recognized is initialized into a corresponding graph node, and a text heterogeneous graph of the text to be recognized is constructed according to a preset part-of-speech path, the text word data of the graph nodes is updated by an attention mechanism, and the features of all graph nodes of the text heterogeneous graph are extracted using the BiLSTM model, and a nested named entity recognition result is obtained after decoding and annotating. The present disclosure can recognize ordinary entities and nested entities accurately and effectively, and enhance the performance and advantages of the nested named entity recognition model.

Abstract: A storage fragment management method and a terminal. The method may be applied to a file system of the terminal, and the file system includes at least one segment. The method includes: first determining, by the terminal, a source segment from the file system based on an aging degree of the segment and a valid block ratio of the segment; then determining, by the terminal from the file system based on an aging degree of the source segment, a target segment whose aging degree is consistent with the aging degree of the source segment; and finally migrating, by the terminal, data of a valid block in the source segment to an idle block in the target segment. This method is used to resolve a problem that power consumption is high when data migration is performed on a storage fragment in an existing log-structured file system.

Abstract: A garbage data scrubbing method includes obtaining an input/output (IO) busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state. When the IO busy/idle status of the terminal at the current moment is the idle state, a discard message is delivered to a storage device, where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and where the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

Abstract: A method for protecting application data includes detecting a deleting operation performed by a first application on first data. The method also includes determining, based on a preset condition, whether to delete the first data of the first application. The method further includes renaming the first data of the first application based on a determination that the first application meets the preset condition. The method additionally includes storing the renamed first data in a memory.

Abstract: This application provides a garbage data scrubbing method and a device, and relates to the field of terminals, to resolve a problem that delivering a discard message in a file system transaction affects a user foreground operation. The method includes: obtaining an IO busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state (S301); and if the IO busy/idle status of the terminal at the current moment is the idle state, delivering a discard message to a storage device (S302), where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.
