一個可蒐集Flash動畫中影像之網路應用系統的開發

在搜尋引擎的發展過程中，多數的搜尋引擎以爬行與蒐集網頁或影像資料為主，而關於如何爬行與蒐集Flash動畫的相關研究並不多，目前雖有少數離線瀏覽工具可供蒐集Flash動畫，不過這些工具多為單機程式，而且若要萃取這些動畫中的額外資訊又必須依賴其它軟體。本研究主要探討如何整合現有Flash動畫蒐集、擷取的相關技術，並以一個離線的工具Swiler為基礎，開發一個稱為Flashare的線上蒐集Flash動畫工具的系統雛型，Flashare提供使用者在瀏覽過程中直接蒐集感興趣的Flash動畫，Flashare以網格式的介面呈現，除了提供經剖析後的各Flash圖像元件的縮圖，並附以萃取的動畫相關基本資訊與外部參考素材，在系統運作上則運用Ajax、Memcached等相關網站技術，以提昇績效。我們除了以三種類型網站所含的動畫測試系統，並邀請Flash動畫之設計者試用和提供參考意見，這些測試的結果與使用意見，除了作為系統修正的參考外，也提供了進一步的開發與研究方向。

In recent development of the technology for search engines, most researches are focused on crawling and harvesting Web page and image data. Fewer researches are on crawling and harvesting Flash movies. Although currently some offline browser utilities are capable of harvesting Flash movie components, most of these tools are offline stand-alone programs. If users want to access additional information of these components, additional tools or operations are required. This study explores approaches to integrate the various Flash movie harvesting and extracting technologies. Based on an available offline Flash movie harvester named Swiler, we develop an online Flash movie harvester prototype called Flashare. Flashare provides facilities for users to collect and parse their interested Flash movie during their web navigation. Flashare also provides visualization facilities to present users with grid of thumbnails of parsed Flash movie components and relevant information. The performance of the prototype is enhanced by the employment of web techniques such as AJAX and Memcached. The prototype is tested with extracting Flash movies online from three types of web sites. We also invite several Flash movie designers to try and use our system. Their comments and suggestions are reviewed for system adjustments or for considerations of further revisions.
