PageRankならぬPeopleRank？
New Items for Your Search and Information Retrieval Reading List
検索方法についての新たな考え方PeopleRankについて
Since tagging images is a popular topic these days, I thought this new paper was worthy of your attention. You've heard of PageRank but now you can read about PeopleRank.
From the abstract:
Our system suggests likely identity labels for photographs in a personal photo collection. Instead of using face recognition techniques, the system leverages automatically-available context, like the time and location where the photos were taken. Based on time and location, the system automatically computes event and location groupings of photos. As the user annotates some of the identities of people in their collection, patterns of re-occurrence and co-occurrence of different people in different locations and events emerge. The system uses these patterns to generate label suggestions for identities that were not yet annotated. These suggestions can greatly accelerate the process of manual annotation.
写真・画像そのものの”類似性”でなく、その画像が”いつ・どこで”使用されたかという情報の関連性を元にグループ化する。そしてFolksonomy的なTaggingシステムを利用してさらに自動分類させていく。
