You need to submit a detailed lab report, to describe what you have done and what you

have observed. You also need to provide explanation to the observations that are interesting or surprising.

Please also list the important code snippets followed by explanation. Simply attaching code without any

explanation will not receive credits.

Portfolio Project

The final portfolio project is a three-part activity. You will respond to three separate prompts but prepare your paper as one research paper. 

Start your paper with an introductory paragraph.

Prompt 1 “Blockchain” (2-3 pages): Explain the major components of blockchain. Be sure to include how blockchain is affecting a global economy and how you see it growing in the future.

Prompt 2 “Big Data” (1-2 pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology?  How does big data affect a global economy.

Prompt 3 “Government and Policies” (1-2 pages):  Discuss the role government plays in a global economy.  Also, look at what policies are currently in place and then discussion what policies should be put in place..Conclude your paper with a detailed conclusion section. 

The paper needs to be approximately six to eight pages long, including both a title page and a references page (for a total of eight to ten pages). 

Be sure to use proper APA formatting and citations to avoid plagiarism.Your paper should meet these requirements: 

  • Be approximately six to eight pages in length, not including the required cover page and reference page.
  • Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
  • Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook.

 This exercise is a simple extension of the word count demo: in the first part of the exercise, you’ll be counting bigrams, and in the second part of the exercise, you’ll be computing bigram relative frequencies. 

Part I: Count the bigrams Take the word count example and extend it to count bigrams. Bigrams are simply sequences of two consecutive words. For example, the previous sentence contains the following bigrams:  “Bigrams are”, “are simply”, “simply sequences”, “sequence of”, etc. Work with the sample collection Bible+Shakes.nouns on Blackboard. Don’t worry about doing anything fancy in terms of tokenization; it’s fine to continue using Java’s StringTokenizer. 

In order for this to run on a cluster, you will need to build a jar file. jar cf jar-file input-file(s) 

Questions to answer: 

1. How many unique bigrams are there? 

2. List the top ten most frequent bigrams and their counts. 

3. What fraction of all bigrams occurrences does the top ten bigrams account for? That is,  what is the cumulative frequency of the top ten bigrams? 

4. How many bigrams appear only once? 

Part II: From bigram counts to relative frequencies Extend your program to compute bigram relative frequencies, i.e., how likely you are to observe a word given the preceding word. The output of the code should be a table of values for F(Wn|Wn 1). Hint: to compute F(B|A), count up the number of occurrences of the bigram “A B”, and then divide by the number of occurrences of all the bigrams that start with “A”. 

Questions to answer: 

1. What are the five most frequent words following the word “light”? What is the frequency of observing each word? 

2. Same question, except for the word “contain”. 

3. If there are a total of N words in your vocabulary, then there are a total of N2 possible values for F(Wn|Wn-1)—in theory, every word can follow every other word (including itself). What fraction of these values are non-zero? In other words, what proportion of all possible events is actually observed? To give a concrete example, let’s say that following the word “happy”, you only observe 100 different words in the text collection.  Does this mean that N-100 words are never seen after “happy” (perhaps the distribution of happiness is quite limited? 

Computer Science Question

 

The collection of data has changed not only the way which we live and work, but also how we communicate. Social media generates tremendous amounts of data which are used from everything from advertising to urban planning.

Your assignment for the week is to perform a brief analysis on the Facebook data provided by Leskovec. Your analysis should include the following:

  • Explain how the data were created.
  • Determine weaknesses/areas of improvement in the data.
  • Identify what research is based off this data.
  • Predict what future research could be based off of this data.
  • Summarize how the data are structured/stored.

Your submission should also include a brief sample research area in which the information could be used. In short, you should actually perform a study using this data. However, for this sample exercise, it may be kept brief (1-2 pages of the final assignment submission).

Support your assignment with at least five scholarly resources. In addition to these specified resources, other appropriate scholarly resources, including older articles, may be included.

Total Length: 8-10 pages, not including title and reference pages

Your assignment should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards. Be sure to adhere to Northcentral University’s Academic Integrity Policy.
