The Large-Scale Concept Ontology for Multimedia (LSCOM) project was a series of workshops held from April 2004 to September 2006〔Naphade, ''et al.'', "Large Scale Concept Ontology for Multimedia: VACE Workshop Report,"〕 for the purpose of defining a standard formal vocabulary for the annotation and retrieval of video. ==LSCOM Mandate== Sponsored by the Disruptive Technology Office (DTO), LSCOM brought together representatives from a variety of research communities, such as multimedia learning, information retrieval, computational linguistics, library science, and knowledge representation, as well as "user" communities such as intelligence agencies and broadcasters, to work collaboratively towards defining a set of 1,000 concepts.〔''( Naphade, ''et al.'', "A Large Scale Concept Ontology for Multimedia Understanding," ppt presentation published by MITRE )〕 Individually, each concept was to meet the following criteria:〔''( Naphade, ''et al.'', "Large-Scale Concept Ontology for Multimedia," IEEE MultiMedia, vol. 13, no. 3, pp. 86-91, July-September 2006. )〕 *Utility: the concepts must support realistic video retrieval problems *Feasibility: the concepts are capable or will be capable of detection given the near-term (5 year projected) state of technology *Observibility: the concepts occur with relatively high frequency in actual video data sets Jointly, these concepts were to meet the additional criterion of providing broad (domain independent) coverage.〔 High-level target areas for coverage included physical objects, including animate objects (such as people, mobs, and animals), and inanimate objects, ranging from large-scale (such as buildings and highways) to small-scale (such as telephones and applicances); actions and events; locations and settings; and graphics. The effort was led by researchers from Carnegie Mellon University, Columbia University, and IBM.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Large Scale Concept Ontology for Multimedia」の詳細全文を読む スポンサード リンク
