| 摘 要： | 经过对用户行为模式调查,照片管理主要涉及了照片的位置、时间、目录以及标签等信息。针对个人照片数据日益增多,由于其大数据量、异构性等特点,传统的管理方式已经无法适应照片的检索需求的现状,该文提出了一种基于标识的照片组织管理方式。根据时空唯一性的特点,通过GeoSOT位置码+时间码唯一标识照片,同时在数据库中存储用户关心的其他标签,并对编码建立了相应的索引。最后,对编码生成和照片检索的效率进行了实验验证,结果表明该组织方式能够高效地管理个人照片数据。

| Abstract: | Through investigation on the user behavior model,it is known that photograph management mainly involves the location and time of the photos,content and tag.As personal photographs are increasing every day,due to its large amount of data,the unstructured characteristic and so on,the traditional way to manage already can't adapt to photograph retrieval requirements.In this paper,a photo organization mode based on identity was proposed.On the basis of the characteristics of uniqueness of time with space,photographs were identified by the unique GeoSOT position code plus time code,and other tags which users concern about were stored in the database,and index was established on photographs'codes.Finally,experiments were made on the efficiency of coding and photograph retrieval;the results showed that the proposed method could effectively manage personal photograph data. |
