See Developing a user centredsentiment analysis website from Twitter feedsThis is an individual piece of coursework.1 GENERAL OVERVIEWThe popularity of “Microblogging” is on the rise for quite some time among online users. Users on amicroblogging site may share their personal updates, thoughts, opinions, and even world news. The powerand impact of microblogging cannot be overlooked in today’s world. A number of organisations arealready using microblogging as a cost-effective way of communicating with customers, building onlinecommunities, product release information, updates, etc. Twitter ( is one suchmicroblogging form that has a massive following (approximately 320 million registered users). It allowsregistered users to post short messages (up to 140 characters) called tweets and reply to or even retweetother users’ tweets. One of Twitter’s key strengths is the number of third party applications that enableusers to interact with the twitter service from a wide range platforms or services.For this coursework, you will be required to design and develop a website based on the users’ twitteraccount feeds by categorising them under ‘sentiments’ (e.g., positive, negative or neutral). All the usersregistered to your website must possess a valid twitter handle from which his/her feeds will be retrieved.You can perform ‘sentiment analysis’ against i) the user’s own tweets or ii) the user’s own tweets andretweets, or ii) user’s home timeline, i.e., users own tweets, retweets, and tweets of other users thathe/she might be following. You need to justify any of the three options that you undertake.Sentiment analysis is one of the hardest aspects of web analytics using microblogging sites’ resources. Itcould be an important starting point to gauge a business’s or brand’s impact on the web, and consequently,the business strategies could be adjusted. For your coursework, you could choose a simplistic algorithmto perform the sentiment analysis. For example, a word like ‘love’ or ‘hate’ appearing in a tweet could beassociated with ‘positive’ or ‘negative’ sentiments, respectively. Remember that identifying ‘perfect’sentiment is not the primary goal of this coursework. The emphasis of this coursework would be more onthe various user centred design principles and techniques that you apply, and the application ofclient/server side web development technologies.TASK 1: ANALYSIS AND DESIGNThe web application is expected to be developed in user centred design approach. The design processneeds to be documented through appropriate design artefacts (e.g. Information Architecture, Personas,Task Analysis, Storyboarding, Prototypes, Evaluation) that show how the design has been conceived andwhich steps were taken to implement a user centred design process. The student is expected to considercontemporary issues (e.g., responsive design, accessibility) in designing the web applications. He/sheshould also provide a clear rationale for his/her design decisions based on user research and best practicesof user centred design. Furthermore, clear evidence and documentation should be shown that a usercentred design process has been followed, and an analysis of the information design for the user interfacehas been carried out.TASK 2: INTERFACE IMPLEMENTATIONYou are required to develop a user friendly web interface to be run on current web browsers that showsthe tweets categorised according to the sentiments. You should make use of appropriate HTML and CSScoding techniques to achieve this. Use of templates and frameworks such as Bootstrap is encouraged butit must be referenced in the code and report. Be aware that marks can only be awarded for modificationsto templates and frameworks, so please make sure you properly distinguish your own work/modificationsin the report.You must make sure that the user interfaces meets usability and accessibility criteria, and conform to usercentred design guidelines and theory. You also need to consider how the user will navigate between pages(if required). All of this must be documented in the report.TASK 3: SYSTEM IMPLEMENTATIONThe system must be hosted on the University of Greenwich IIS server (your CMS I: drive) or a similarcollaborative college system. All sources of code must be fully referenced. Do not implement anythingthat you do not understand as you may have to explain all your code to a tutor at an acceptance testingsession.You are required to develop a prototype system using a dynamic web programming language (e.g., PHP)and a suitable database (e.g., MySQL) with the following functionalities:1. Every user registered into the system should possess a valid twitter handle. You should also createa twitter handle yourself before registering to your own system if you don’t already have one. Theregistered user is encouraged to follow other users of Twitter from his/her own twitter account.The twitter feeds should be retrieved from this registered twitter handle of your system. Notethat, your system should have provisions to have multiple users registered with their respectivetwitter handles.2. You should have a registration system in place for your system. You can assume that the twitterhandle provided by the user during registration is valid – no error checking is required. Onceregistered, a user should be able to edit his/her own profile that contains a short biography,contact details, picture, etc.3. After registration, the user can log into the system using username/password or email/passwordor any other combination that you deem appropriate. Unauthorised access should be prohibited.Password should be saved inside the database encrypted. After login, the tweets related to theuser’s twitter handle with which he/she have registered will be retrieved. Again note thatdepending on the logged user, the retrieved tweets may vary as every user is expected to registerand login with his/her own Twitter handle.4. A simple algorithm like Cosine Similarity or Naïve Baye’s Classifier is sufficient to categorise theretrieved tweets according to the different sentiments for showing meaningfully in the website.You can associate various keywords to the different sentiments ‘offline’ initially (e.g., love, thankyou etc. reflecting ‘positive’ sentiment). However, you should also provide provisions inside yourwebsite to update (add/delete/edit) the keywords corresponding to the sentiments by aregistered user.5. The visualization aspects of the user interface, e.g., how many tweets arepositive/negative/neutral (and/or in percentages) should come from the user centred study thatyou performed in Task 1 with justification. You are encouraged to also include other types ofreport or results that you deem appropriate inside your “sentiment analysis website” arising fromthe user centred design and analysis.TASK 4: REPORTYou are required to present a formal report, which must be uploaded by the due date. The report is thebasis for the marking and credit can only be given for work that is presented in the report. The reportshould not simply be a collection of screenshots, you must explain your design and development decisionsand provide evidence to back them up either from the literature or your own studies. The report shouldinclude the following: Table of Contents. The URL of the prototype web site. A sample username/password or email/password or anyother combination that you have used to log into your system should be supplied inside thereport through which the website can be accessed. Include your registered twitter accounthandle as well for this particular user. All these information should be inside the FIRST PAGE ofyour report. The key issues and findings of the report divided into Tasks 1, 2 and 3. A section containing the evaluation and testing of the site.The report should include code snippets (not the full code) and screen images. A ZIP of the code shouldalso be uploaded along with the PDF of the report.2 ASSESSMENT CRITERIAAssessment 1: Analysis and Design 40%Marks will be awarded for documentation of the two stages and understanding of tools/techniques chosen.Especially, whether contemporary issues (e.g., responsive design, accessibility) of designing webapplications have been considered, and evidence that an analysis of the information design for the userinterface has been carried out (requirement of Formative Assessment – interim upload). They should alsoprovide clear rationale of their design designs, and evidence of whether user centred design process hasbeen followed (this can be added to their interim report and be included inside their final report).Assessment 2: Interface Implementation 20%Marks will be awarded for Usability and Accessibility as well as their written (if any)/modification to thegenerated HTML/CSS code for both versions.Assessment 3: System Implementation 30%Marks will be awarded for functional front-end (running on web browsers) and back-end Database design,and completeness of the delivered prototype’s functionalities.Assessment 4: Report Presentation, Completeness, Referencing 10%Marks will be awarded for general presentation, referencing style, completeness and documentation ofAssessments 1- 3._____________________________________________________________________Total 100%_____________________________________________________________________All the above tasks will be evaluated w.r.t. the following deliverables:Deliverable 1: An interim uploadAn interim report (Week 7 – Friday (4th November, 2016)) as a formative assessment which the studentshould utilise to obtain useful feedback from the tutors that he/she might incorporate for their finalupload. It should consist of the user centred design and analysis part (please see Assessment 1 / Task 1for more details) of the coursework.Deliverable 2: A Final ReportYou are required to present a formal report, which must be uploaded by the due date. The report is thebasis for the marking and credit can only be given for work that is presented in the report. The reportshould not simply be a collection of screenshots, you must explain your design and development decisionsand provide evidence to back them up either from the literature or your own studies. ). It should consistthe whole documentation of Tasks 1, 2 and 3.The report should include code snippets (not the full code) and screen images. It should include thefollowing: Table of Contents.The first page of the report should list the URL of the prototype web site together with ausername and password that you have already registered with a twitter account (specify theregistered twitter account as well). It might be used by the assessor to log-in withoutregistering to your website with his/her own account.The key issues and findings of the report divided into Tasks 1, 2 and 3. You should include all therequirements that are specified inside the each individual Task here.A section containing the evaluation and testing of the site. Apart from the contents related to the explanation of their web application, the presentation andcoherence of the report structure, grammar, referencing, etc. will also be taken into account in evaluatingthe final report.Deliverable 3: A Prototype SystemA ZIP of the code of your website should also be uploaded along with the PDF of the report. Propercredentials should be provided by the student to assess the website properly inside the report. Forexample, the URL of the prototype web site together with a username and password that you havealready registered with a twitter account (specify the registered twitter account as well) which can beused to login to your system.An acceptance test will also be arranged by your tutor near the end of the term where you willshow your prototype system to the tutor/assessor on Week 12. You are expected to explain your system,and answer any queries that the tutor/assessor might have. You can utilise this session’s feedback toenhance your prototype during your final upload.3 GRADING CRITERIADistinction (>=70%)Well-developed work that satisfies the coursework requirements in design and implementation to ahigh standard.
