中文简介:
由于存在许多问题,媒体检索仍然是一个悬而未决的问题:语义差距,根据媒体档案的维度和多样性进行缩放的难度,计算负担。上下文信息的使用被认为是解决此类问题的最佳选择,但没有最终解决方案可用于共同利用内容和上下文。在这个领域,Glocal项目提出了“事件”这一概念,作为组织和索引媒体以进行浏览和检索的一种方式。 Glocal已经定义了能够捕捉事件复杂性及其关系的模型。软件工具旨在创建新的事件模型,并通过同行之间的社交互动及时发展。此外,一组工具将允许用户生成事件实例并以自动或半自动方式将它们与媒体集合相关联。还特别注意与用户的交互,允许通过定制界面个性化和适应不同的用户类别和应用程序。为了演示和验证Glocal方法,项目联盟不断致力于构建媒体语料库,跨越不同的领域,针对不同的社区,从专业人士到普通用户。
课程简介: Media retrieval is still an open problem, due to many problems: the semantic gap, the difficulty in scaling according to dimension and diversity of media archives, the computational burden. The use of contextual information is considered among the best options to solve such problems, but no ultimate solutions are available to jointly exploit content and context. In this domain, the Glocal project proposes the notion of “event” as a way of organizing and indexing media for browsing and retrieval purposes. Glocal has already defined models able to capture the complexity of events as well as their relationships. Software instruments are being designed to create new event models and make them evolve in time through the social interaction among peers. Furthermore, a set of tools will allow users to generate instances of events and associating them to media collections in an automatic or semi-automatic way. The interaction with the user is also treated with special care, allowing personalization and adaptation to different user categories and applications through customized interfaces. To demonstrate and validate the Glocal approach, the project consortium is continuously working at the construction of media corpora, spanning different domains and targeting diverse communities, from professionals to common users.
