    摘要: 社群網路的興起大幅改變了現代社會的溝通模式。使用者互動時產出的巨量資料，經過蒐集、儲存、分析，能幫助研究人員在許多領域進行更深入的工作，包括災變信息(crisis informatics)、趨勢分析、社會關係(social relation)等。為讓研究人員將心力專注於資料的分析上，建構穩定的資料蒐集與管理平台供研究人員方便處理就有其必要性。
    本研究參考目前推特資料蒐集、大量資料儲存所遇到的狀況及限制，定義出一些基本系統設計方式，並完成一個推特資料蒐集與管理平台。我們
    採用「事件、工作」的模式以儘量減少使用者設定重複蒐集條件，再搭配「一工作、一Access Token」的作法讓系統的工作與工作之間速限不會互相影響；其次，考量到一般狀況下，系統進行大量資料儲存會遇到硬體擴充性問題，本平台蒐集資料後，先儲存於NoSQL，再將資料從NoSQL迅速轉換到一般關聯式資料庫。
    我們並進行了一些資料搜集的實驗，並與許多學者使用的其他兩個工具進行推特蒐集的比較，初步結果顯示我們的平台有一定的優勢。
    The rise of social media, such as Twitter, has significantly influenced the mode of communication in modern society. By collecting, storing and analyzing the massive amount of user interaction data from social media, researchers can conduct more in-depth work in many areas, such as disaster information dissemination (crisis informatics), trend analysis and social network analysis, etc. To help researchers focus on the analysis of data, it is necessary to construct a robust data collection and management platform.
    In this thesis, we investigate the issues and restrictions of current tweets data collection and storage, and present a modular design and implementation of tweet collection and management platform based on Twitter’s API. Two salient features of our platform are event-job based data collection tasks and access token pool. Specifically, researchers may lauch multiple job to collect the tweets related to an event with less duplicate tweets. By adopting the one job one access token approach, multiple jobs can run separately and will not affect the rate limit of each other. Besides, considering the common situation of tweet burst in many events, our platform first stores the collected data into HBase, a popular NoSQL system, and then quickly migrate them to a standard relational database.
    To evaluate our platform, we have conducted a few data collection experiments, and made a comparison with two other popular tweet collection tools, The preliminary results show that our platform has certain advantages over them.
