Embodiment 1

[0070] see figure 1 , this embodiment provides an investment measurement method based on big data mining technology, including:

[0071] S1: Obtain business data in various business systems of the enterprise to obtain the first data source; analyze offline business documents through a self-developed parsing program to obtain the second data source;

[0072] Specifically, business data includes all data of historical items. The offline system document may be the document data of the historical project, and the template of the document data is split and parsed to obtain the second data source.

[0073] S2: cleaning and arranging the data of the first data source and the second data source according to a preset data cleaning model, so as to obtain valuable cleaning data that can be used for analysis;

[0074] Specifically, data cleaning is mainly used to exclude low-quality data and function as data filtering. The cleaning data includes the unique code of the historical projec...

Embodiment 2

[0094] see Figure 7 , Embodiment 2 provides a new method for measuring and calculating tasks on the basis of other embodiments, including:

[0095] S11: Receive the user's login instruction for the user to register or log in to the analysis application platform;

[0096] Specifically, for users who log in for the first time, registration is required. In order to protect data security, during the registration process, the administrator also needs to grant the registered user permission. The user must be successfully logged in to complete the login.

[0097] S12: Receive a new creation instruction from the user, and create a new measurement task on the analysis application platform;

[0098] Specifically, the analysis application platform also counts the cumulative number of times the platform has completed measurement and the cumulative number of copies of the platform's production target cost sets, so that the user can check the usage of the platform.

[0099] S13: Receiv...

Embodiment 3

[0119] see Figure 8 , 9 , Embodiment 2 On the basis of Embodiment 2, a method for determining the priority level of cost fetching is added: the data that matches the characteristic index is searched and called in the data warehouse, and the calculation parameter is specifically:

[0120] Set up multiple search areas, and arrange the search areas according to the regional administrative level from low to high;

[0121] Specifically, the search can be performed according to the order in which the project address entered by the user is located in the same county, the same city, the same province or municipality directly under the Central Government. If there are no matching items in the same county, search within the same city, and so on.

[0122] According to the order of regional administrative levels from low to high, according to the characteristic index, the data in each search area is sequentially searched in the data warehouse;

[0123] When there is data matching the ...

Abstract

The investment measurement method based on the big data mining technology provided by the present invention obtains the business data in each business system of the enterprise to obtain the first data source; and analyzes the offline business documents through the self-developed parsing program to obtain the second data source. data source; cleaning and sorting data of the first data source and the second data source according to a preset data cleaning model to obtain cleaning data; integrating the cleaning data to obtain a data warehouse; building an analysis application platform; receiving The user's operation creates a new measurement task; the measurement task is analyzed to obtain the measurement result. The use of application analysis can greatly improve the efficiency of investment calculation. By replacing manual analysis with application analysis, the work time can be shortened to 1 / 30 of the original, which improves the calculation efficiency and shortens the calculation time. Using real historical business data, the quality of analysis results can be guaranteed, and the investment measurement method is an important investment decision-making tool for real estate projects.

Description

technical field [0001] The invention belongs to the technical field of big data, in particular to an investment measurement method based on big data mining technology. Background technique [0002] The real estate industry is a pillar industry of my country's economy, and the annual transaction volume of the residential real estate market alone exceeds 10 trillion yuan. Whether it can obtain good projects is related to the life and death of real estate enterprises. Investment calculation is used to calculate the income and expenditure of the project to be acquired, and then obtain the expected income of the project. It is an essential tool for enterprises to make project acquisition decisions. [0003] However, the current project investment calculation adopts manual calculation method, which takes a long time, resulting in low calculation efficiency, manual detailed calculation is likely to cause errors in calculation results, and high requirements for calculation personne...
