    Abstract: 本研究個案公司現在所面臨問題,如同其他家公司類似問題。投資可觀金錢,人力、物力只為保存一堆不知如何使用的日誌。為了只是內外部稽核證明的確依法規執行。真正要從這些日誌中找出有用資訊卻不知如何下手。市面上大數據商業用分析軟體除了價錢昂貴,再者數據可能需要給廠商進行分析,這相關個資是企業最不想流露。

    近幾年,科技創新是為帶動經濟成長和國家進步的主要動力。尤其人工智慧。正在快速改變全球的產業發展,是未來的重要趨勢。台灣為了與世界科技同步,已選定AI為我國下世代的發展主力計畫。個案公司發現同業中已開始佈局,不論是人才培訓或硬體投資皆以起步。勢必開始對這塊領域有所涉略,畢竟科技軍備競賽是沒有停止的一天。

    那要收集那些數據,有了數據那下一步要分析什麼?企業營運是需資金所支持,每一次的人力、物力投資都是成本,投入的成本必需有利益產出,產出的利益如果有其發展性才會有更進一步的投資計畫。個案公司想到公司每年面對外部大大小稽核,如客戶稽核、海關稽核和ISO14000資訊安全管理稽核。這些稽核有相同的項目都是針對關鍵營運系統,如ERP。舉凡稽核人員都會問到帳號使用紀錄。這反映出公司內控是否有做好。依據過往紀錄,常常是缺失結尾。這些問題的答案就在這些成千萬筆的紀錄中,但偏偏面對稽核員稽核當下往往拿不出來。後續接踵而來是一連串改善缺失計畫,這到還是輕微,有些歐美客戶認為這是重大缺失,直接取消訂單,這損失實在無法估計。

    個案公司決定以收集ERP 日誌資料為主。對外面對稽核單位提出跟ERP 使用者記錄相關問題,答案能從這些資料擷取出來。稽核零缺失帶來實質效益訂單穩定,公司聲譽高標準。對內管理者目前是無法得知系統真實上線人數,針對下一年年度帳號預算規劃,帳號追加購買這一項往往無法有一數據輔助決策。買多是浪費開銷,帳號不足使用者抱怨連連,延遲公司日常作業。基於上述兩項原因,個案公司預期大數據分析目前帳號使用分佈能帶來實質效益,打聽同業已經執行大數據分析專案過程,另外公司在最近一年來聘請如工研院或大學教授幫同仁上大數據相關課程。發現都是使用Python作為大數據分析工具,一來開源無須再付出額外授權費用,再者相關套件成熟。業界使用頻繁,容易找到參考範例,彼此溝通有相同語言。決定使用Python 作為此次日誌分析工具。
    ;Recent year, the software and hardware of Artificial Intelligence technology improved quickly. Each company tries to collect any data they have. For example, manufacturing try to collect the data of the mechanism. The raw data collected that have more than one hundred Terabytes. The data just collected finish. These collected dates not clean transfers of meaningful data, they cannot improve business income. These companies consider using Commercial software to analyze the big data they have. The much Commercial software license cost and data expose issues that these companies have more concern.

    Our research focus on ERP Audit logs collect and analysis. The company that we study recent year faced Audit Of Accountant. The auditor asks questions about the security issue of the ERP System. For example, the ERP system users login time, from which machine, and they make any changes in the ERP system. The questions above can be found correct answer in their ERP audit logs. The audit logs recorded that raw data about the mention questions before. The company does not know how to use the raw data to get answers for the Audit Of Accountant. Due to the issue the company gets audit punishment.

    The company decides to use open source of the big data to solve the audit issue. They try to analyze the audit log raw to get some good results. For example, current online ERP system users, user login from which computer, the counts of the ERP program used. The company reference others companies have already used big data to reduce daily work. Finally, the company tries to use open source ′Python′ to the main big data analysis tool. Python become the most popular big data analysis tool recent year. The Python communities more and the Python package good for analysis big data.
