  6. In This Session … • Introduction • Nature of research • Definitions • Research as a process • Defining the research problem, Research protocol design, • Undertake research, and document • Classifying Research • The field of research, • The purpose of research • To review existing knowledge, to describe some situation or problems, the construction of something novel, explanation. • The approach to research, • Theoretical, Laboratory experiment, field experiment, case-study and survey. • The nature of research • Pure basic research, Testing of existing theory, • description of the state-of-the-art, specific problem solution.

  7. Definitions #1 • Research is defined in [] • “Research is often described as an active, diligent, and systematic process of inquiry aimed at discovering, interpreting, and revisingfacts. This intellectualinvestigation produces a greater knowledge of events, behaviors, theories, and laws and makes practical applications possible. The term research is also used to describe a entire collection of information about a particular subject, and is usually associated with the output of science and the scientific method.”

  8. Definitions #2 • Research is: • A process through which we question our knowledge, change and improve our understanding, • Set in some context, • Often multi-disciplinary • Central to the way we deal with the world. • Because research is so important it is essential that the researcher be fully acquainted with the methods by which research is made possible. • Research requires: • an open enquiring mind • a creative orientation • a critical, analytical approach • logical reasoning • accuracy and care • dedication and honesty

  9. The Nature of Research • Research as a process • Defining the research problem, • Research protocol design, • Undertake research, • Documentation and dissemination • Guiding Questions for defining the research problem • What is the particular problem? • What are the symptoms? • Where do the industrial partners feel a pain? • What is it that they cannot do, or cannot do well enough, which they will, hopefully, be able to do, or do better, as a consequence of your proposed research?

  10. Guiding questions: Defining the research problem #1 • What is the generalisation of that particular problem? • Why are they suffering in this way? Why can't they get round their problem without your research? There may be a chain of 'becauses' until you get to a 'root cause'. • What is the line of attack? • What theories will you bring to bear? What is your ‘big idea’ as to how that underlying cause might be attacked. • What is your ‘angle’. • What is the plan? • How and where and when will your industrial partners contribute? • How will they be preparing to take the results forward after the end of the project?

  11. Guiding questions:Defining the research problem #2 • How will you change the world? • If your ideas prove right, how will the results be exploited so as to make a significant impact on industrial practice? • If exploitation requires a change in business processes, • how will migration to the new way of working be achieved?

  14. Categories of CS Research • Research in CS including IS and AI can be grouped as follows: • The study of what is possible • Including both mathematical and less rigorous forms of theorising. • The study of existing (naturally occurring) • Including information processing systems E.g. animals, societies, brains, minds, .... • Research involving creation of new • useful information processing systems, and research directly related to engineering applications. • The creation and evaluation of tools, • Including formalisms and techniques to support all these activities.

  15. Research Process • Research Process: • Selection of a Research Topic • Interest and Significance • Originality and Feasibility • The Literature Survey • Identifying a Topic, state-of-the-art and/or practice • Literature Review • Project Design • Choose research method, define detailed Research Plan • Planning and Management • Implement Research Design, • Undertaking the work • Data Collection & Analysis • Evaluating the results • Draw Conclusions • Writing Up the Research and reporting • Disseminating the results/findings

  16. Doing an MSc. Project Perform literature search Select a topic Make a plan Write up Gather & analyse data Create Gantt chart Produce estimates Plan resources Decide objectives Develop Work Struct. Student Project Work Structure Source Ref: to be added

  17. Next Session … Qualitative Research: Lecture 2

  18. Tutorial 1: Scientific Reasoning Required Work: Read the handout several times and write a one page summary picking out the points that seem important to you for a discussion next week. Tutorial Topic
