US Patent 11256869 Word vector correction method

The present disclosure provides a word vector correction method using artificial intelligence technology. A word vector correction method using a word vector with n dimensions includes generating a first (n+1)-dimensional word vector using an average of elements included in a first n-dimensional word vector; generating a second (n+1)-dimensional word vector using an average of elements included in a second n-dimensional word vector; and determining whether a first word corresponding to the first word vector and a second word corresponding to the second word vector are similar to each other on the basis of specified synonym information.
