Data Cubes Research Article

The goal of the project was to research a current topic in Data Analytics that was not covered extensively in class and provide a brief summary of research, how this topic relates to other subjects covered in class, and an example of how it has this tool has been applied in practice. I learned how data cubes work and how they can take a 2-D data store (rows and columns) and analyze it in much higher dimensions. This expands upon the information we learned about relational databases along with providing a solution to obtaining better association mining. As well, I learned about the ‘roll up’ and ‘drill down’ features available to cubes because of their allowance for hierarchical relationships. In all, it really changed my thinking of how dimensions relate to databases, especially how rows and columns can not only limit one’s data but as well, there perspective. http://community.mis.temple.edu/cbreece/articles/

Sentiment Analysis

The short research was about Sentiment analysis, it’s application and it’s relation to what we studied in our class. Sentiment analysis is an analysis that extracts subjective information from the source material. This way of contextual mining is primarily used to classify the source material as positive, negative or neutral. My goal was to research about the topic to connect it to data analytics. I learned about how unstructured data can be converted into semi-structured data (CSV, JSON, XML) and perform analysis on that to draw inference. With the use of APIs, data analysts perform sentiment analysis and it’s used in many enterprises to learn about customer behavior, purchase patterns and  public opinon to implement new strategies, introduce a product, revise a commercial.etc.

Extra Credit Assignment

The goal of this project was to create a write-up with the purpose of displaying my ability to understand and describe an aspect of data analytics to any future employers. The aspect I chose to describe was text mining and sentiment analysis. I was also able to describe a real world example of the 2016 presidential campaign to show how these techniques were used in regards to the media’s attitudes toward the two presidential candidates. By completing this project, I learned how text mining and sentiment analysis are related to data mining as well as learning that these two techniques can help see trends that are not clearly seen or known from the raw data.

Artificial Intelligence and It’s Advancements

AI or artificial intelligence is a field of study that relates to artificial or computer intelligence generated by machines and not the human brain.  It is designed to mimic the human brain to solve problems and generate ideas.  Artificial Intelligence is a controversial topic in this day and age with some fearing that computer generated intelligence will exceed the human mind and eventually surpass any human capabilities. However, with the help of AI we are now capable of having computer driven cars, and many other technology based items that help make life easier.  Management Information Systems and artificial intelligence go hand in and because much of AI is based off of data analytics and predicting outcomes based on data.  In class we are taught how to predict outcomes based on previous data collected and we also analyze and take into account any hazards that could affect that data outcome.  Analyzing the risks and predicting while knowing why such things happen is a key part in MIS and AI.  An example of AI in real life would be Tesla’s driving and driving assist cars.  What these cars do is predict actions taken on the road by other drivers while detecting and adapting to hazards ahead.  These computers use cameras and sensors around the car to be able to drive and see a full 360 degrees of the road.  The cars programmers have programmed the computer in the car to spot hazards ahead and adapt to them accordingly.  For example, if a child were to run across the street after a ball, the car would detect the child as a hazard and stop the car.  These self-driving and driving assisted cars help reduce the number of accidents on the road while helping drivers navigate the road more smoothly and without any accidents.  With the invention of AI, humans are now capable to exceeding the boundaries of human capabilities while helping ease day to day life of the average human being.  As time goes on and technology becomes more advanced, humans everyday life will continue to become easier and computers will become more incorporated in a person’s daily life.

Blockchain Could Solve Data Quality Issues

In response to the spiked-interest in cryptocurrencies, blockchain was created to record cryptocurrency transactions. Blockchain is an innovative technology that utilizes Peer to Peer (P2P), a vast network of computers operating a decentralized server to actively store cryptocurrency transactions into a secure and unalterable state. The process of blockchain goes as follows: a transaction is requested; a P2P receives the transaction; the P2P authenticates the transaction; a block of data is built up of authenticated transactions; and then the block of data is permanently joined with other blocks of data, forming a blockchain (Buterin et al.).

Additionally, blockchain has been found to be useful in storing, not just cryptocurrency-related transactions, but almost all transaction types (Sarikaya). What makes blockchain unique is its use of a decentralized system. In most cases, data is centrally stored which makes targeting easier for cyber attackers (Sarikaya). However, blockchain utilizes a system where all the data is stored within a decentralized network of nodes, ensuring the integrity of the data (Sarikaya).

Comparatively, both blockchain and data analytics manipulate data using algorithms, yet both methods have different objectives with the data (Sarikaya). Data analytics focuses on interpreting and drawing predictions from data, whereas blockchain is used to validate and store data (Sarikaya). The Extract Transform Load (ETL) process, a subject covered in the MIS2502 course, focuses on the data extraction step of preparing data for analyzing. One of the biggest challenges associated with ETL is maintaining data quality. Data analysts struggle to sustain data quality because of errors in the data, missing data, or redundancies in the data.

Also, the course reveals that the primary method data scientists use to maintain data quality is to verify the data through sampling manually. Blockchain could be an important tool for ETL as it can sustain and restore data integrity through its data verification process. Primarily, the data is stored and verified by a vast network of authorized nodes (Sarikaya) which eliminates the necessity to verify the data manually. Blockchain could effectively restore data quality and securely store validated data, resulting in a significant increase in data analysis efficiency.

The goal of this project was to research a topic within data analytics that relates to what we have learned in class. I chose the area of artificial intelligence because of its impact on revolutionizing multiple industries. Artificial intelligence is the capability of machines to perform and think on a human level. AI has been very controversial in society because of the idea of “too much” intelligence. From my research I was taught all the different ways AI works and how the information is extracted and used. In MIS 2502 we focus a lot of big data and data mining which artificial intelligence seeks patterns within. AI builds on our class topics because instead of humans computing outputs with the technology as a tool the technology is now the main key player. We have already seen AI used in revolutionary aspects such as self-driving vehicles. Many worry about safety when human control is replaced by technology which is why testing is huge in this project. “Any test begins by sending out a driver in a conventionally driven car to map the route and road conditions,” Google software engineer Sebastian Thrun explained in a blog post. “By mapping features such as lane markers and traffic signs, the software in the car becomes familiar with the environment and its characteristics in advance” (Woollaston, 2016). However as far as we have come with artificial intelligence humans are still needed to perform certain steps when it comes to programing AI which takes some worries away from the idea of “too much” intelligence.

Research Papers

The project for MIS 2502 (Data Analytics) was to write two essay about different topics that relate to the MIS field. The first essay was about machine learning. In this essay I talked about what machine learning is and how it is used. I gained knowledge on how much of a role machine learning in technology plays a huge role in our everyday lives and usually goes unnoticed. The second essay was describing what data science ethics is. In this essay I talked about the main ethics is data science how how they can effect the information or conclusions we draw from data after it is interpreted.
