The invention belongs to the technical field of
digital text editing, and particularly relates to an OFD document modification
system and method oriented to cloud
collaboration,
computer equipment and a computer readable storage medium. The
client comprises an operation layer, and the
server comprises a
coordination layer and a conflict decision layer; the operation layer is dominated by an OT
algorithm, and real-
time compression of operation is carried out by adopting an incremental patch mechanism of the OT
algorithm; the method comprises the following steps: predicting subsequent operation of a user through an LSTM neural network, locally pre-generating an operation chain, and when prediction accuracy is greater than a preset threshold, sending the pre-generated operation chain to a
server; adding a unique mark to each operation sent to the
server; the
coordination layer is dominated by a CRDT
algorithm, performs type judgment on received operation, processes the operation in different
modes, combines all results and performs dual-structure storage on combined versions, and the conflict decision-making layer performs conflict detection after the versions are combined. According to the invention, conflicts caused by
simultaneous editing by multiple persons can be reduced, and editing efficiency is improved.
