2. How to Write Dissertation 1 st Question: When to start writing Ph.D. thesis? Start as early as possible, do not wait you are fully ready. Write early, write often, writing is thinking! Assumption: successfully defend the proposal; At least start with an outline or skeleton; Do not have to start from the 1 st section to the end; Start taking notes of problems, goals, brief descriptions, experimental designs and expected outcomes; The theories, algorithms or experiments, as well as the thesis may require numerous revisions to cover weaknesses/errors; Set deadline/due dates for each stages!! 6

2. How to Write Dissertation Common Skeleton (formal structure depends on Universities): Abstract Introduction Background and Literature Review Research Questions/Problem Statement Solutions, Methodologies and Experiments Evaluations and Discussions Conclusions References Appendices Others: Table of Contents, Acknowledgements, etc 7

How to Write Dissertation Principles of Thesis Organizations: Take the readers’ views/focuses into account; Logically Clear, Sound, thorough, Reasonable; Be honest and justified; Highlight the novel ideas and main contributions; For each section, ask yourself relevant questions to validate whether your writings have meet the requirements of each section Basic Routine: Goal->Writing->Question 8

Abstract General introduction of the background Briefly introduce the problem you want to address Summary of your solution and methodologies State a bird view of your results/conclusions Highlight your novel ideas and main contributions Is it concise? Is it clear and easy to learn the background and the targeted problem? Did you clearly indicate your solutions, conclusions and highlight your contributions? 9
10
2. How to Write Dissertation 2). Introductions General introduction to what the thesis is about Summarize the research questions/problems Indicate why this is a worthwhile problem Give an overview of your solution, experiment and main results/conclusions Can general readers easily understand the introduction? Did you explain some terms to avoid readers’ confusion? Did you briefly introduce your solutions and contributions? Did you highlight the novelty? 10
11
2. How to Write Dissertation 3). Background and Literature Review Give the background to let the readers know and understand your topic & the knowledge of this area The state of the art; related work, existing research Organize these by logical and reasonable ideas, not simply by time/author, etc Is the background clear enough? Is the literature review well organized? Is the literature review thorough enough? 11
12
2. How to Write Dissertation 4). Research Questions/Problem Statements Concise statement about the problems you want to address Justification, indicate the problem is unanswered based on the previous literature review Thoroughly discuss why it is worthwhile to solve this problem Will readers be convinced to agree with your view on the problems, about the originality, novelty and applicability? Did you refer to some literature references to convince your points? 12
13
2. How to Write Dissertation 5). Solutions, Methodologies and Experiments Main purpose: to convince the examiners that you have answered the question or solved the problem by your own solutions It may require several sections to thoroughly explain the solutions, experiments and evaluations; here I simply split them into two. Show relevant methodologies/work to your solution If there were blind alleys or dead ends, do not include them unless they can be used to serve that you have solved the problem Can readers clearly understand your solutions? Did all these parts have a logical basis and convinces? Did you mention the experimental conditions and limitations? 13
14
2. How to Write Dissertation 6). Evaluations and Discussions Analyze your experimental results and evaluate your assumptions/solutions performance Focus on the positive contributions of the results, also explain the negative results Reasonably discuss the limitations of your solution, focus on the scale of the applicability Did you thoroughly evaluate the experimental results? Did you thoroughly discuss the relevant issues, such as limitations, flaws, etc? 14
15
2. How to Write Dissertation 7). Conclusions Conclusions: short concise statements about the results of work you have done; must be directly relevant to the problem you raised in this thesis; How you complete your promise? Summary of contributions: whether your results can contribute to the knowledge of your area; organize from most to least important. Original? Novel? Thorough? Meaningful? Future research: in order to let other researchers pick up relevant work and follow your tracks. Feasible? Reasonable? 15
16
2. How to Write Dissertation 8). References Closely tied to the literature reviews in previous sections Examiners usually scan this list looking for important works in the field, which may be considered as a preliminary assessment If your examiners are one of the experts in your topic, it may be necessary for you to read their relevant papers and put them into the references Do not just list them, make sure you have referred them in the main body! Organize them either alphabetically by author surname or order of citation in your thesis 16
17
2. How to Write Dissertation 9). Appendices This part may include materials impede the smooth development of your presentation but can contribute to justify the results of the thesis. For example: program listings, huge tables of data, mathematical proofs or derivations 17

3. Dissertation Style The formal structure/format depends on the University; Be clear, sound, reasonable as literature style; Latex tool is recommended for writing; Grammar & logic written; Keep the figures and tables clear enough and well organized; Spell check, also check for missing chapter or figure references; Avoid simply use “obviously/clearly”, etc; Avoid simply use “XX is the most important …”; Avoid personal moral judgements and self-assessment; More: How to Write A Dissertation or Bedtime Reading for People Who Do not Have Time To Sleep 18

4. More about Dissertation Results of your dissertation defense: Pass, Fail, Major Revision, Small Revision, etc Evaluate your thesis by yourself: Did you clearly and reasonably describe all? Did you logically demonstrate your solution? Were all questions well answered? Is there a significant contribution to previous knowledge? Ethical Issues: Original, Honest, Justified Thorough literature review Keep original, honest & justified about ideas & evidences Take references seriously (literature, figure, table, etc) 19
