【摘要】：隨著金融大數據技術的發(fā)展和投資者個性化、多樣化的需求,金融知識服務面臨著更大的挑戰(zhàn)。投資者如何獲取及時準確的實時數據,如何估計某一只債券的未來價格和未來收益,如何在收益相當的債券中選擇風險最低的債券,如何在最短的時間內使得收益最大化等等,都是投資者關心的熱點問題。以上問題亟需異構信息處理技術、數據挖掘方法的技術支持,因此,本文主要研究從海量金融信息中發(fā)現、挖掘出更有價值信息的方法和策略,應用于企業(yè)債券知識服務。債券信息的獲取是知識服務的基礎。為了保證知識服務的準確性和高效性,首先需要獲取全面而準確的數據,其次,通過進一步去噪、優(yōu)化等處理,將金融數據處理為結構化數據,為整個服務過程中的推薦策略和趨勢預測提供準確的數據保障。為了使投資者投入更少的精力而獲得相對較高的收益,提出具有針對性的同類益高債券推薦策略。從債券投資者的角度出發(fā),深入分析、研究了投資過程中影響債券收益率的關鍵特征組合,從而為用戶提供更高效的、個性化的投資策略。債券趨勢預測為投資者提供了債券價格和收益變化趨勢的參考。利用機器學習的方法基于債券價格時間序列、行業(yè)、公司新聞等信息對債券未來趨勢進行預測,綜合多個影響債券價格走勢的特征因素及多種特征形式,提高了預測的準確性。綜上所述,本文利用自然語言處理技術、數據挖掘方法從海量金融數據中獲取數據信息,并處理為結構化數據,進一步發(fā)現、挖掘更有價值的信息,利用債券推薦策略和趨勢預測方法為用戶提供個性化、多樣化且高效的金融知識服務。
[Abstract]:With the development of financial big data technology and the individualized and diversified demand of investors, financial knowledge service is facing more challenges. How to obtain timely and accurate real-time data, how to estimate the future price and future income of a certain bond, how to choose the lowest risk bond in the equivalent bond, how to maximize the return in the shortest time, etc. Investors are concerned about hot issues. These problems need the technical support of heterogeneous information processing technology and data mining method. Therefore, this paper mainly studies the methods and strategies of mining more valuable information from the massive financial information, and applies them to corporate bond knowledge services. The acquisition of bond information is the basis of knowledge service. In order to ensure the accuracy and efficiency of knowledge service, first of all, we need to obtain comprehensive and accurate data. Secondly, through further de-noising, optimization and other processing, the financial data is processed into structured data. Provides the accurate data guarantee for the recommendation strategy and the trend forecast in the whole service process. In order to make investors invest less energy and obtain relatively high returns, the paper puts forward the recommendation strategy of the same kind of higher interest bond. From the point of view of bond investors, this paper analyzes the key characteristics of bond yield in the process of investment, and provides users with more efficient and personalized investment strategies. Bond trend forecast provides investors with reference to bond price and yield trends. The method of machine learning is used to predict the future trend of bond based on the time series of bond price, industry, company news and so on. The accuracy of prediction is improved by synthesizing many characteristic factors and various characteristic forms that affect the trend of bond price. To sum up, this paper uses natural language processing technology, data mining method from massive financial data to obtain data information, and processing as structured data, and further discover, mining more valuable information, Using bond recommendation strategies and trend forecasting methods to provide users with personalized, diversified and efficient financial knowledge services.
