摘要

照片並不單單只是一張圖片，一張照片往往勝過千言萬語，透過瀏覽個人的照片集更透露出個人與其社交圈聯絡人之間的互動關係。隨著數位相機的普及化，人人都能夠擁有一台專屬的數位相機，輕易地紀錄日常生活社交活動的點點滴滴，也因此個人照片的數量與日劇增。由本論文提出的Social Familiarly Hypothesis假說，個人與其社交圈聯絡人之間的互動關係的種類與強度能夠利用個人的相片集做判斷，利用此假說與數位照片所記錄"people"與"event"的元資料(Metadata)，我們能夠系統地分析個人與其 社交圈聯絡人之間的互動關係，進而建立此論文所定義的個人人際網路(Personal Social Network or PSN)。

此論文提出一個實際可行的方法分析個人的照片集來建立出PSN，並利用PSN來表達個人的社交行為模式。問卷調查指出儘管利用照片集所建立的PSN並不完整，但卻能夠表現出互動較為頻繁的個人社交圈。另外，此論文應用擴散激發理論(Spreading Activation Theory)於建立的PSN來達到預先主動式照片分享推薦機制，實驗結果顯示預先主動式照片分 享推薦機制能夠達到平均80\%的求全率(Recall)與75\%的求準率(Precision)。

A picture is worth a thousand words. A personal photo collection may reveal the complex social interactions between the person and his/her social contacts. As digital cameras become increasingly pervasive, people are empowered to capture with minimal efforts many aspects of their daily activities and social interactions. This research explores the hypothesis that social connections can be extracted from knowledge about the people and events in the pictures. This thesis defines the personal social network (PSN) as a model of personal social behavior, and proposes a practical approach to weaving personal photos into PSNs. The user study shows that the constructed PSN can represent one's regular social space even if it is not the actual personal social network. In addition, the resulting PSN is used to provide photo sharing recommendations by spreading activation over the PSN. The experimental results show that the PSN constructed automatically from photos can achieve reasonably good performance, yielding an average precision of 80% with a recall of 75%.
