Web-Oriented Tools for Data Analytics
Tie amount of open data is increasing and it could be effectively used in different fields of studies.
Tiere are numerous web-oriented services which allow user to visualize open data such as world bank open data (https://data. worldbank.org/), Google Public Data Explorer (https://www. google.com/publicdata/directory), Global Health Observatory (https://www.who.int/gho/en/), Registry of Open Data (RODA) on AWS (https://registry.opendata.aws/), They contain open data as already graphical visualization of the data. But it could be more efficient to have a tool which could allow flexibly to manipulate with open data.
An online service was developed by integrating the following frameworks: Laravel (back-end), Vue.js (front-end), Bootstrap, Pyodide, Highcharts, CodeMirror.
Tie developed service has the following functions (Figure 9.7):
- • Creation of the Python scripts.
- • Execution of Python scripts.
- • Authorization on the server to implement saving scripts in user account.
- • CRUD operations on Python scripts.
- • Download files from the web.
- • Python library support (matplotlib, pandas, and numpy).
- • Service instruction.
Figure 9.7 Interface of the developed service.
"Die typical scenario for the usage of the developed service includes the following steps:
- • User could download .py file with required method or write code directly within the webpage with the usage of the embedded editor.
- • Results could be visualized as the graphics and will be printed in the embedded Python console.
Ethics, Regulations, and Law Constraints for Data Analytics
Analytics and AI are powerful tools that have real-word outcomes. Applying practical, ethical, and legal constructs and scenarios enables getting effective analytics results.
"Die GDPR, which entered into force last Friday, May 25, guarantees the citizens the ability to decide on the processing of their data through a series of options linked to each of the uses that companies make them or by exercising the rights recognized in the regulations themselves.
Consequently, the new legislation will also limit the use of Big Data that many companies have been developing for commercial or security purposes. It was precisely the concern generated in this area in the European authorities that led to the development of a unifying regulation that would put an end to the gap that the digital revolution has been leaving in recent years.
Therefore, entities must change their strategies in this regard, as the illicit use of customer data could lead them to pay fines of up to 20M EUR in the case of the most serious infractions.
In the search for new solutions that allow them to make legal use of the data generated, risk analysis is the first step that companies will have to take as well as the creation of a figure in charge of making good use of the data of customers. To guarantee this, the companies’ control bodies themselves must have sufficient human and material resources to determine whether there is illicit benefit or not in that use of data.
In short, with the application of the GDPR, customers gain power and control over their data, while companies must comply with a series of obligations that limit them in their commercial activities through that data. However, the proper management of this information can be a great opportunity for them because it will lead to more direct and personalized advertising that goes beyond the current analysis and segmentation of customers.
The application of the GDPR, which really came into effect on May 25, 2016, was suspended until this year for companies to have enough time to adapt their regulations in accordance with the new legislation. However, according to a study by Leet Security, 88% of companies have not completed the process of adaptation to the regulations.
This investigation was aimed at reviewing some relevant data analytics techniques which have been applied to three different case of study: prediction of sports competition results based on open data, the prediction of the cold sickness, and companies’ cyber risk assessments.
We have demonstrated that the use of appropriate analysis tools can provide relevant information for the final purpose of each case study. Different parameters have been obtained to assess the quality of the model and the prediction obtained.
The conclusion is that there is no unique method, model, or approach which provides the best results in every scenario. An appropriate study must be performed on the different parameters; in some cases, a preprocessing of the data is required, and the election of the most appropriate regression or classification methods is not trivial.
