UCC와 SNS 등을 통해 개인 미디어가 다양한 방식으로 생성됨에 따라 미디어를 분석하고 인지하는 기술에 대한 연구가 진행되고 있으며, 이를 통해 객체 인지의 수준이 향상되었다. 그 결과 기존의 제목, 태그 및 스크립터 정보를 이용한 추론 방식과 달리 미디어에서 인지되는 객체를 활용하는 영상 분류 추론 연구가 수행되고 있다. 하지만 추론을 위한 미디어 온톨로지 모델링을 사람이 직접 수행해야 하기 때문에 많은 시간과 비용이 발생하는 단점이 있다. 따라서 본 논문에서는 미디어 분류를 위한 온톨로지 스키마 모델링의 자동화 방법을 제안한다. 영상에서 인지되는 객체의 빈도에 따른 OWL-DL 공리의 특성을 고려하여 온톨로지 모델 생성의 자동화 방안에 대하여 설명한다. 유튜브에서 수집한 15가지의 카테고리에 대한 영상으로부터 온톨로지 모델을 자동 생성하여 추론을 통해 미디어 분류의 정확도에 대한 실험을 수행하였다. 실험결과 15가지 영상 이벤트의 행위 약 1500개에 대하여 영상 분류를 수행한 결과, 86%의 정확도를 얻었고, 온톨로지 모델링의 자동화 방법에 대한 타당한 성능을 보였다. With the personal-media development that has emerged through various means such as UCC and SNS, many media studies have been completed for the purposes of analysis and recognition, thereby improving the object-recognition level. The focus of these studies is a classification of media that is based on a recognition of the corresponding objects, rather than the use of the title, tag, and scripter information. The media-classification task, however, is intensive in terms of the consumption of time and energy because human experts need to model the underlying media ontology. This paper therefore proposes an automated approach for the modeling of the media-classification ontology schema; here, the OWL-DL Axiom that is based on the frequency of the recognized media-based objects is considered, and the automation of the ontology modeling is described. The authors conducted media-classification experiments across 15 YouTube-video categories, and the media-classification accuracy was measured through the application of the automated ontology-modeling approach. The promising experiment results show that 1500 actions were successfully classified from 15 media events with an 86 % accuracy.

미디어 온톨로지의 시공간 정보 확장을 위한 분산 인메모리 기반의 대용량 RDFS 추론 및 질의 처리 엔진

이완곤(Wan-Gon Lee),이남기(Nam-Gee Lee),전명중(MyungJoong Jeon),박영택(Young-Tack Park) 한국정보과학회 2016 정보과학회논문지 Vol.43 No.9

대용량 미디어 온톨로지를 이용하여 의미 있는 지능형 서비스를 제공하기 위해 기존의 Axiom 추론뿐만 아니라 다양한 추론을 활용하는 지식 확장이 요구되고 있다. 특히 시공간 정보는 인공지능 응용분야에서 중요하게 활용될 수 있고, 시공간 정보의 표현과 추론에 대한 중요도는 지속적으로 증가하고 있다. 따라서 본 논문에서는 공간 정보를 추론에 활용하기 위해서 공공 주소체계에 대한 LOD를 대용량 미디어 온톨로지에 추가하고, 이러한 대용량 데이터 처리를 위해 인메모리 기반의 분산 처리 프레임워크를 활용하는 공간 추론을 포함하는 RDFS 추론 시스템을 제안한다. 또한 추론을 통해 확장된 데이터를 포함하는 대용량 온톨로지 데이터를 대상으로 하는 분산 병렬 시공간 SPARQL 질의 처리 방법에 대해서 설명한다. 제안하는 시스템의 성능을 측정하기 온톨로지 추론과 질의 처리 벤치 마킹을 위한 LUBM과 BSBM 데이터셋을 대상으로 실험을 진행했다. Providing a semantic knowledge system using media ontologies requires not only conventional axiom reasoning but also knowledge extension based on various types of reasoning. In particular, spatio-temporal information can be used in a variety of artificial intelligence applications and the importance of spatio-temporal reasoning and expression is continuously increasing. In this paper, we append the LOD data related to the public address system to large-scale media ontologies in order to utilize spatial inference in reasoning. We propose an RDFS/Spatial inference system by utilizing distributed memory-based framework for reasoning about large-scale ontologies annotated with spatial information. In addition, we describe a distributed spatio-temporal SPARQL parallel query processing method designed for large scale ontology data annotated with spatio-temporal information. In order to evaluate the performance of our system, we conducted experiments using LUBM and BSBM data sets for ontology reasoning and query processing benchmark.
