Technical Field
Various embodiments of the present invention relate to an enterprise evaluation execution apparatus based on an ESG and an operation method thereof, and more particularly, to an apparatus for collecting and analyzing news reports on the internet, analyzing and scoring risks related to environmental, social, or administrative structural topics owned by an enterprise, and an operation method thereof.
Background
Recently, enterprises have paid more attention to risk management, and simultaneously, have evaluated their own enterprises and other enterprises in multiple angles, and have applied such evaluation results to risk management of investment, co-procurement, production lines, and the like.
Generally, enterprises are generally evaluated based on financial data that can be obtained quantitatively, but recently, methods for evaluating enterprises and analyzing risks based on non-financial data have been earnestly developed. In the financial data disclosed by the enterprise, although the content unfavorable to the corresponding enterprise is not reflected, the reliability of the financial related report provided by the enterprise is questioned. If the reason for the need for enterprise analysis through non-financial data is examined, as SNS activities of people through the Internet are increasingly active, the reputation of an enterprise may be shaken by specific news-disseminated events or the like to the enterprise or products, and in addition, risks to the corresponding enterprise may be increased due to crimes or health-related news of the owner of the enterprise, which are actually difficult to analyze through financial data. Therefore, the enterprise is analyzed not only by the financial data but also by the non-financial data, and thereby the enterprise evaluation can be performed more precisely.
Under the trend, a methodology for dividing non-financial data into three topics of ESG (environmental, Social and Governance) for analysis is silently developed.
Although there are companies that make evaluation reports for companies based on non-financial data such as an ESG, the non-financial data is subjective and the report making speed is relatively slow, and thus there is a disadvantage that it is difficult for companies to utilize the data. In order to improve such a drawback, in terms of collecting ESG-related news reports on the internet by a computer program or the like and automatically analyzing and performing enterprise evaluation, the news reports have many difficulties in automating the classification and evaluation of the news reports due to non-normative data.

The ESG enterprise evaluating apparatus 100 determines whether news is related to which enterprise, which topic, and the like, by morpheme analysis, similarity calculation between documents, and the like, in collecting news reports, and can perform classification merging of classification between similar reports for the first time.
If referring to (b) of fig. 1, the ESG enterprise evaluation apparatus 100 may perform a more precise news story classification operation on the basis of the news stories collected and classified and merged for the first time. The ESG enterprise evaluation apparatus 100 first determines whether the collected news is related to the ESG, that is, whether the collected news is related to at least one of the environment, the society, or the administration structure, and then determines which subject of the environment, the society, or the administration structure the collected news is related to and classified in performing the news report classification operation. Finally, the ESG enterprise evaluation apparatus 100 can perform more detailed directory classification for each news report classified into three subjects of environment, society, and governance structure.
Referring to fig. 1 (c), the ESG enterprise rating apparatus 100 derives a final enterprise rating score based on the categorized news stories. In this process, the ESG enterprise evaluation apparatus 100 may calculate an evidence level for a main word included in a news report and a probability of which the news report belongs to an environment, a society, or an administration structure, for each cluster unit.
For convenience of explanation, the ESG enterprise rating device 100 of the present invention is illustrated and described as a case where a final ESG enterprise rating score is derived through three steps, and such steps may be divided or integrated, and may be embodied in a smaller or greater number of steps.

In the manner as described above, the ESG enterprise rating apparatus 100 may finally derive an ESG enterprise rating score for each cluster as a similar report set.
Fig. 6 is a block diagram schematically illustrating a process of deriving an ESG enterprise rating score from a process of collecting news reports by the ESG enterprise rating device 100 according to one embodiment of the present invention.
If referring to fig. 6, news stories are data that are fundamental in performing business evaluation, the ESG enterprise evaluation device 100 may collect news stories on the internet at regular or irregular intervals S601.
Then, the ESG enterprise evaluation device 100 may classify the collected news stories by enterprise and by date S603, and analyze the corresponding stories using an appropriate morpheme analyzer according to the language in which the collected news stories are produced S605.
The ESG enterprise evaluation apparatus 100 calculates the similarity between news reports through the similarity analysis between vectors after vectorizing the news reports based on the news reports on which the morpheme analysis is completed, collects related news together, and performs classification and merge S607. In this process, the ESG enterprise evaluation apparatus 100 may perform vectorization on each news report using TF-IDF, and may calculate the similarity between each news report by cosine similarity calculation.
The ESG enterprise evaluation apparatus 100 may classify S609 as to which topic in the environment, society, and governance structure each news report collected belongs to, and which in the inventory of topics in the environment, society, and governance structure belongs to. In this process, the ESG enterprise evaluation apparatus 100 may classify each news report into whether or not the report is related to the execution of the ESG enterprise evaluation in a TRUE or FALSE (TRUE or FALSE) form, and in each classification step, may adopt an appropriate machine learning algorithm to generate data for exercise so that the ESG enterprise evaluation apparatus 100 executes learning by the corresponding algorithm. The user of the EGG enterprise evaluation apparatus 100 can perform each classification of step S609 by verifying the ESG enterprise evaluation apparatus 100, which performs learning using the machine learning algorithm and the training data, using the test data.
The ESG enterprise evaluating apparatus 100 may calculate an evidence level value of each ESG topic of the corresponding cluster in each cluster unit classified in step S607, and calculate an ESG probability value of the corresponding cluster S611. In this process, the ESG enterprise rating means 100 may classify nouns extracted from news reports into a plurality of word categories, such as a set of environmental, social, governance structures, enterprise risks, other related issues. Then, the ESG enterprise evaluation apparatus 100 may calculate an evidence level value about the environment, the society, and the treatment structure in the set, and may calculate an ESG probability value.
Finally, the ESG enterprise evaluation device 100 may calculate a final ESG enterprise evaluation score S613 based on the evidence level value and the ESG probability value calculated in step S611. In this process, the ESG enterprise evaluation device 100 may use the ESG probability value calculated in step S611 and the evidence level value classified as the set of enterprise risks.
According to an embodiment of the present invention, the ESG enterprise rating apparatus 100 may include a function of providing a basis for deriving a corresponding score when an individual or a business using an ESG enterprise rating result requires a basis for deriving a rating score for a specific business. That is, when calculating the evaluation score for a specific business report, information that the corresponding evaluation score is greatly affected depending on the frequency number of specific words present in the report may be provided, or a report including the corresponding word may be searched for and provided.
As described above, the ESG enterprise evaluation apparatus 100 according to the embodiment of the present invention performs automated enterprise evaluation, so that when similar news reports about a specific enterprise are released on the internet, it is possible to determine which topic of the environment, society, and governance structure the corresponding news report relates to, and to what degree the risk of the corresponding topic is significant.
On the other hand, the ESG enterprise rating apparatus 100 according to an embodiment of the present invention may also be embodied in a computer readable recording medium as computer readable code. The computer-readable recording medium includes all kinds of recording devices that store data that can be read by means of a computer system.
For example, as the computer-readable recording medium, there are Read Only Memory (ROM), Random Access Memory (RAM), compact disc read only drive (CD-ROM), magnetic tape, hard disk, floppy disk, removable storage device, nonvolatile memory (flash memory), optical data storage device, and the like.
In addition, the computer-readable recording medium can be distributed to computer systems connected via a computer communication network, and stored and operated as codes that can be read in a distributed manner.
While the embodiments of the present invention have been described with reference to the drawings, it will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
