This application belongs to the field of
data processing technology, specifically involving an integrated
traceability method for language learning and practice results across multiple platforms. The method includes: acquiring
learning behavior data from multiple platforms; standardizing and converting the multi-platform
learning behavior data and writing a unified event serial number to generate a unified learning
record; writing user identifiers, timestamps,
record summary values, and previous
record summary values into the unified learning record to generate a chained record sequence; storing the chained record sequence in a storage network, and generating a
restricted access copy and an integrity
verification copy when the sharing request is verified; performing behavior fragment coverage checks and supplementary collection based on the integrity
verification copy to generate a complete set of learning behaviors; and integrating the complete set of learning behaviors across platforms to generate a learning trajectory archive. This application can balance record reliability, sharing
controllability, and trajectory integrity.
