Coursework Brief:
Crowdfunding has been a popular way for many, from people to big companies, to fund risky, uncertain, or otherwise obscure projects. The risk in a crowdfunded project comes from the inability of the project controllers to deliver what they promise; and given the huge rise in low quality projects requesting funding, the ability of the platforms being able to detect when things start to go awry is becoming a necessity.
In this project, you are given a dataset1 of comments arising from two well-known crowdfunding platforms (Kickstarter and IndieGoGo), along with the sentiment of the comment. These comments have been tagged by real people, so there is also a confidence score associated to it. The variables are:
ID: Comment ID (not predictive)
Text: Comment in text format. Scraped from the web.
Sentiment: Either positive (1) or negative (0).
Confidence: How confident was the scorer on the sentiment score.
Starting from this sample, your task is to create a model that infers the sentiment from the text comments and design the way the company will put it into production, using what you know about Deep Learning and Big Data technologies. For this purpose, write a report that answers the following questions:
1. Reflect critically on the required big data capabilities needed for the company to operate. How would you use big data technologies to manage the volume of reviews stored in the site? Comment on what technologies

you believe are necessary (e.g. Hadoop, NoSQL, traditional relational databases, data lakes, data warehouses, etc). Remember to use relevant literature to justify your answer.
Preprocess the text so that it can be used in Deep Learning. Explain your decisions and describe the resulting datasets.
Study the distribution of the dataset and extract basic statistics from the document. At the very minimum, discuss the words that are repeated the most, the length of the phrases, and the distribution of the comments.
Train several Neural Networks to predict whether a comment is speaking in a positive or negative way about a project. Try at least two different embeddings (e.g. fastText, GloVe, BERT, etc.) as input layers, with one of them being training your own embedding; and two different architectures, one of them including more than one hidden layer (i.e. not Kims model). Discuss and justify your choice of the architecture, layers, and other parameters for each of the architectures. Comment on how you think it is best to use the confidence score.
Calculate your accuracy, AUROC, and your confusion matrix over the test set for each of your models. Generate a plot with all the ROC curves of your models. Which embedding works best? Which architectures?
Discuss how you would implement your model into production, referring to technologies, process and people, to improve the success chances of your model.

Nature of Assessment: This is a SUMMATIVE ASSESSMENT. See Weighting section above for the percentage that this assignment counts towards your final module mark.
Word Limit: +/-10% either side of the word count (see above) is deemed to be acceptable. Any text that exceeds an additional 10% will not attract any marks. The relevant word count includes items such as cover page, executive summary, title page, table of contents, tables, figures, in-text citations and section headings, if used. The relevant word count excludes your list of references and any appendices at the end of your coursework submission.
You should always include the word count (from Microsoft Word, not Turnitin), at the end of your coursework submission, before your list of references.
Title/Cover Page: You must include a title/ cover page that includes: your Student ID, Module Code, Assignment Title, Word Count. This assignment will be marked anonymously, please ensure that your name does not appear on any part of your assignment.
References: You should use the Harvard style to reference your assignment. The library provide guidance on how to reference in the Harvard style and this is available from: http://library.soton.ac.uk/sash/referencing
Submission Deadline: Please note that the submission deadline for Southampton Business School is 16.00 for ALL assessments.
Turnitin Submission: The assignment MUST be submitted electronically via Turnitin, which is accessed via the individual module on Blackboard. Further guidance on submitting assignments is available on the Blackboard support pages.
It is important that you allow enough time prior to the submission deadline to ensure your submission is processed on time as all late submissions are subject to a late penalty. We would recommend you allow 30 minutes to upload your work and check the submission has been processed and is correct. Please make sure you submit to the correct assignment link.
You will know that your submission has completed successfully when you see a message stating Congratulations your submission is complete. It is vital that you make a note of your Submission ID (Digital Receipt Number). This is a unique receipt number for your submission, and is proof of successful submission. You may be required to provide this number at a later date. We recommend that you take a screenshot of this page, or note the number down on a piece of paper. You should also receive an email receipt containing this number, and the number can be found after submitting by following this guide. This method of checking your submission is particularly useful in the event that you dont receive an email receipt.
You are allowed to test submit your assignment via Turnitin before the due date. You can use Turnitin to check your assignment for plagiarism before you submit your final version. See Viewing Your Originality Report for guidance. Please see the Module Leader/lecturer on your module if you would like advice on the Turnitin Originality report.
The last submission prior to the deadline will be treated as the final submission and will be the copy that is assessed by the marker.
It is your responsibility to ensure that the version received by the deadline is the final version, resubmissions after the deadline will not be accepted in any circumstances.
Important: If you have any problems during the submission process you should contact ServiceLine immediately by email at [email protected] or by phone on +44 (0)23 8059 5656.
Late Penalties: Further information on penalties for work submitted after the deadline can be found here.
