Abstract: A deep learning model based on attention using an embedding scheme for continuous variables of tabular data. A method of constructing the deep learning model based on attention includes converting tabular data of structured data having a mixture of categorical variables and continuous variables into embedding values and training a network model including a transformer block, a linear layer block, and a sharing function for the sharing of an attention between the transformer block and the linear layer block by using the embedding values.

Abstract: Disclosed is a system for generating test documents for context-sensitive spelling error correction. The system includes: an input unit inputting an error-free document for generating an error document; an error target word segment test unit checking possibility of an error in a word segment by sequentially examining word segments of the entire sentences in the document input through the input unit and searching for a candidate word appearing at the corresponding position together with surrounding context; an error word candidate selection unit selecting error word candidates among candidate words found at the corresponding position by considering edit distances to a correct word and keyboard typographical errors; and an error word determination and presentation unit calculating probabilities of an error word candidate and its surrounding context and determining an error word of the highest priority as a final error word.
