Abstract

In e-commerce, rapid and accurate automatic product classification according to product information is important. Recent developments in deep learning technology have been actively applied to automatic product classification. In order to develop a deep learning model with good performance, the quality of training data and data preprocessing suitable for the model are crucial. In this study, when categories are inferred based on text product data using a deep learning model, both effects of the data preprocessing and of the selection of training data are extensively compared and analyzed. We employ our CNN model as an example of deep learning model. In the experimental analysis, we use a real e-commerce data to ensure the verification of the study results. The empirical analysis and results shown in this study may be meaningful as a reference study for improving performance when developing a deep learning product classification model.

전자상거래에서 상품 정보에 따른 신속하고 정확한 자동 상품 분류는 중요하다. 최근의 딥러닝 기술 발전은 자동 상품 분류에도 적용이 시도되고 있다. 성능이 우수한 딥러닝 모델개발에 있어, 학습 데이터의 품질과 모델에 적합한 데이터 전처리는 중요하다. 본 연구에서는, 텍스트 상품 데이터를 기반으로 카테고리를 자동 유추할 때, 데이터의 전처리 정도에 따른 영향력과 학습 데이터 선택 범위 영향력을 CNN모델을 사례 모델로 이용하여 비교 분석한다. 실험 분석에 사용한 데이터는 실제 데이터를 사용하여 연구 결과의 실증을 담보하였다. 본 연구가 도출한 실증 분석 및 결과는 딥러닝 상품 분류 모델 개발 시 성능 향상을 위한 레퍼런스로서 의의가 있다.
