Abstract

Currently, NTIS (National Technology Information Service) is building an interactive search service based on artificial intelligence technology. In order to understand users' search intentions and provide R&D information, an interactive search service is built based on deep learning models and morpheme analyzers. The deep learning model learns based on the log data loaded when using NTIS and interactive search services and understands the user's search intention. And it provides task information through step-by-step search. Understanding the search intent makes exception handling easier, and step-by-step search makes it easier and faster to obtain the desired information than integrated search. For future research, it is necessary to expand the range of information provided to users.

현재 NTIS(National Technology Information Service)는 인공지능 기술을 기반으로 대화형 검색 서비스를 구축하고 있다. 이용자의 검색 의도를 파악하고 과제정보를 제공하기 위해 딥러닝 모델과 형태소 분석기를 기반으로 대화형 검색 서비스를 구축한다. 딥러닝 모델은 NTIS와 대화형 검색 서비스를 활용할 때 적재되는 로그 데이터를 기반으로 학습을 진행하고 이용자의 검색 의도를 파악한다. 그리고 단계별 검색을 통해 과제정보를 제공한다. 검색 의도 파악은 예외처리를 용이하게 해주며 단계별 검색은 통합검색보다 쉽고 빠르게 원하는 정보를 얻을 수 있도록 한다. 향후연구로는 인공지능 기술이 접목된 성장형 대화형 검색 서비스로써 이용자에게 제공하는 정보의 범위를 확대해야 한다.
