Ensuring that investment projects are smoothly constructed as planned is an important means to ensure the implementation of investment.

[0003] The risk assessment of the implementation schedule of investment projects is the main means to ensure the smooth construction of investment projects. It means that after risk identification, the overall risk level of the implementation schedule of investment projects is determined through full, systematic and comprehensive consideration of the risk factors of the project, and the construction plan is adjusted according to the assessment results.

[0043] See also Figure 1 The project implementation schedule risk assessment method provided by the first embodiment of the present invention comprises the following steps:

[0044] S10: constructing an investment project implementation progress risk knowledge base through a number of past project progress anomaly analysis reports, wherein the investment project implementation progress risk knowledge base includes a number of main categories and a number of factor names associated with the main categories, and setting factor weights for the factor names;

[0045] The step S10 comprises:

[0046] S110: Obtain subject names of several past project progress anomaly analysis reports, obtain initial categories from the subject names, perform duplicate elimination processing on several initial categories to obtain several main categories, and separate several past project progress anomaly analysis reports into several report sets based on the main categories;

[0047] The subject names of the abnormal progress analysis reports of past projects are generally: abnormal analysis report of XX highway construction project, abnormal analysis report of XX building construction project, and the initial category can be determined by extracting the subject names, which are highway construction, building construction, etc. After the main category is clarified, the abnormal progress analysis reports of past projects corresponding to the same main category can be associated with the main category.

[0048] S120: performing word segmentation processing on the report set to obtain a plurality of words, obtaining the occurrence frequencies of the words, and selecting factor names from the plurality of words based on the occurrence frequencies;

[0049] The word segmentation processing method is now widely used and will not be described here. After obtaining the word, the number of occurrences of the word is obtained, and the frequency of occurrence is obtained based on the number of occurrences and the total number of the word, and the words are sorted according to the frequency of occurrence, and the word with a higher frequency of occurrence is selected as the factor name. In some embodiments, after obtaining the factor name, the factor name can be determined through expert review. Taking highway construction as the main category as an example, the factor name is land expropriation, environmental assessment, and land approval;

[0050] S130: Obtaining a single negative evaluation result and a single positive evaluation result corresponding to the factor name from the report set, and obtaining a total negative evaluation result and a total positive evaluation result of the report set;

[0051] Select the report set corresponding to a certain main category, and extract the previous project progress abnormality analysis report therein, and extract the result data of the previous project progress abnormality analysis report together, that is, whether there is a risk or not. It can be understood that the existence of a risk is the total negative evaluation result, and the absence of a risk is the total positive evaluation result. Furthermore, if the factor name is land expropriation, environmental assessment, and land approval, then passing and failing are the single positive evaluation result and the single negative evaluation result.

[0052] S140: Based on the number of the report set, obtaining a first number corresponding to the single negative evaluation result, a second number corresponding to the single positive evaluation result, a third number corresponding to the total negative evaluation results, and a fourth number corresponding to the total positive evaluation results;

[0053] S150: determining a first weight component by using the first quantity and the third quantity, determining a second weight component by using the second quantity and the fourth quantity, and obtaining a factor weight based on the first weight component and the second weight component;

[0054] The first weight component=the first quantity / the third quantity, and the second weight component=the second quantity / the fourth quantity.

[0055] The calculation formula of the factor weight is:

[0056] ω si =0.5ω gre +0.5ω terr ,

[0057] Among them, ω si represents the factor weight corresponding to the i-th factor name, ω terr represents the first weight component, ω gre Represents the second weight component.

[0058] S20: determining the project category of the investment project information to be evaluated, comparing the project category with the plurality of main categories respectively, selecting a target category from the plurality of main categories, and selecting the plurality of factor names corresponding to the target category as screening names;

[0059] In this embodiment, the project category is obtained by the subject name of the investment project information to be evaluated, which is consistent with the acquisition method of the main category. The project category is compared with the main category to determine the factor name affecting the investment project information to be evaluated, that is, the screening name.

[0060] S30: Obtaining result information corresponding to the screening name from the information of the investment project to be evaluated, wherein the result information includes pass and fail;

[0061] The step S30 comprises:

[0062] S310: Using the screening name as a keyword, selecting a screening statement from the information of the investment project to be evaluated;

[0063] The information of the investment project to be evaluated is subjected to keyword screening based on the screening name to extract the screening statement containing the screening name.

[0064] S320: performing word segmentation processing on the screening sentence to obtain screening words, and comparing the screening words with preset words to obtain result information;

[0065] The preset words also include passed and failed.

[0066] S40: performing assignment processing for the screening name based on the result information to obtain an assignment result corresponding to the screening name, determining a risk score of the investment project information to be evaluated through the factor weight and the assignment result, and completing risk evaluation based on the risk score;

[0067] The assignment result is 0 or 1.

[0068] The step S40 comprises:

[0069] S410: If the result information is passed, determine that the assignment result is 0, and associate the assignment result with the screening name;

[0070] S420: If the result information is failed, determine that the assignment result is 1, and associate the assignment result with the screening name;

[0071] The risk score is obtained by:

[0072]

[0073] Among them, P j represents the risk score of the jth investment project information to be evaluated, Indicates the result of assigning the i-th screening name corresponding to the j-th investment project information to be evaluated, represents the factor weight of the i-th screening name corresponding to the j-th investment project information to be evaluated, and n represents the number of screening names corresponding to the j-th investment project information to be evaluated.

[0074] S430: Compare the risk score with a scoring threshold. If the risk score is greater than the scoring threshold, determine that the investment project information to be evaluated has risks. If the risk score is less than the scoring threshold, determine that the investment project information to be evaluated has no risks.

[0075] The risk knowledge base is constructed based on the abnormal analysis reports of the previous project progress, and the different main categories are distinguished, and then the factor weights of the same factor name in different main categories are distinguished, thereby improving the accuracy of risk assessment; by obtaining the result information, the risk score of the investment project information to be assessed is determined based on the result information and the factor weight, thereby realizing the intelligent transformation of the supervision of the implementation progress of investment projects from relying mainly on manual experience to data-driven, reducing the workload and improving the efficiency and quality of the assessment.
