“怎么拍出拳？”这个问题可以由演员、化妆师、导演和摄影师提出。虽然他们都可以问同样的问题，但他们并不都在寻求同样的答案。在给定的领域内，基于他们扮演的角色，该领域的代理有不同的视角，他们希望从自己的视角得到问题的答案。在这个例子中，一个演员想知道在拍摄一场涉及拳击的场景时如何表演。化妆师感兴趣的是如何为演员化妆，以显示可能由击打造成的瘀伤。同样，一个导演想知道如何指导这样一个场景，一个摄影师正在寻求指导，如何最好地拍摄这样一个场景。这种基于角色的视角差异是用于电影行业信息管理的Loculus框架的基础。Loculus框架利用agent的视角对给定域内的信息进行提取和分类。该框架使用代理在领域本体中的角色定位及其与本体中其他概念的相关性来确定代理的视角。由于该领域缺乏领域本体，因此必须为电影行业开发领域本体。建立了一个基于规则的相关度评分来计算概念与本体的相对相关度，然后将其用于Loculus系统的信息开发和分类。迄今为止进行的评价取得了可喜的结果，并表明利用视角可以产生新的信息提取和分类方法。
"How do you film a punch?" This question can be posed by actors, make-up artists, directors and cameramen. Though they can all ask the same question, they are not all seeking the same answer. Within a given domain, based on the roles they play, agents of the domain have different perspectives and they want the answers to their question from their perspective. In this example, an actor wants to know how to act when filming a scene involving a punch. A make-up artist is interested in how to do the make-up of the actor to show bruises that may result from the punch. Likewise, a director wants to know how to direct such a scene and a cameraman is seeking guidance on how best to film such a scene. This role-based difference in perspective is the underpinning of the Loculus framework for information management for the Motion Picture Industry. The Loculus framework exploits the perspective of agent for information extraction and classification within a given domain. The framework uses the positioning of the agent’s role within the domain ontology and its relatedness to other concepts in the ontology to determine the perspective of the agent. Domain ontology had to be developed for the motion picture industry as the domain lacked one. A rule-based relatedness score was developed to calculate the relative relatedness of concepts with the ontology, which were then used in the Loculus system for information exploitation and classification. The evaluation undertaken to date have yielded promising results and have indicated that exploiting perspective can lead to novel methods of information extraction and classifications.
