Abstract

The Smartphone, one of essential mobile devices widely used recently, can be very effectively applied to capture knowledge on the spot by jointly applying the pervasive functionality of cloud computing. The process of knowledge capturing can be also effectively automated if the topic of knowledge is automatically identified. Therefore, this paper suggests an interdisciplinary approach to automatically acquire knowledge on the spot by combining technologies of text mining-based topic identification and cloud computing-based Smartphone. The Smartphone is used not only as the recorder to record knowledge possessor's dialogue which plays the role of the knowledge source, but also as the sensor to collect knowledge possessor's context data which characterize specific situations surrounding him or her. The support vector machine, one of well-known outperforming text mining algorithms, is applied to extract the topic of knowledge. By relating the topic and context data, a business rule can be formulated, and by aggregating the rule, the topic, context data, and the dictated dialogue, a set of knowledge is automatically acquired.

최근에 들어 많은 관심과 인기 속에 사용되고 있는 스마트폰은 클라우드 컴퓨팅의 편재적 기능성을 접목하여 즉각적인 지식의 획득에 효과적으로 활용될 수 있다. 또한 지식의 주제어 또는 명칭을 자동으로 파악하여 해당 지식을 저장할 수 있다면 전반적인 지식 획득 과정이 자동화될 수 있다. 본 논문은 텍스트마이닝 기반 주제어 추출 기술과 클라우드 스토리지 기반 스마트폰을 접목하여 지식이 발생되는 지점 및 시점에 즉각적으로 해당 지식을 획득할 수 있는 학제적 방안을 제시한다. 이를 위해 스마트폰은 지식이 포함된, 지식소유자의 대화를 녹음하는 역할을 함과 동시에 지식소유자의 대화의 내용을 부가적으로 특성화 할 수 있는 상황정보를 채취할 수 있는 센서의 역할을 수행한다. 또한 기계학습 알고리듬 중 텍스트마이닝분야에서 우수한 성능을 나타내는 것으로 알려진 Support Vector Machine 알고리듬을 사용하여 해당 대화의 주제어를 추출한다. 파악된 주제어와 상황정보를 연관시켜 일종의 비즈니스 규칙을 생성할 수 있으며, 최종적으로 규칙, 주제어, 상황정보, 그리고 문서화된 대화를 종합하여 하나의 지식을 자동으로 획득할 수 있다.
