  3. CMP3265 – Assessment 1 - Portfolio Overall Specification 1. Students will be given exercises by individual tutors on professional issues and research. Students will then build up a portfolio of items in answer to these exercises. The subject-matter will be related to the Learning Outcomes of the module specification. The portfolio of items will be an opportunity to reflect on and theorize about real-time incidents that take place during the course. 2. As the second part of your portfolio, you must write a report which synthesizes and critically evaluates the learning gained from the portfolio of exercises, and from lectures in the seminar series which you attended in Term 2. This analysis should display an appreciation of professional/ ethical / methodological practice / research in IS and computer science.

  4. CMP3265 – Assessment 2 – Research Proposal Overall Specification You should prepare a research proposal of approximately 1500 words. This will allow you to prepare for the research project that may be undertaken during the dissertation phase of the degree and also to achieve the Learning Outcomes (2.1 and 2.2 (also partly 1.1-1.3)) of this module. General Idea Your Masters project has to be founded in some research area of informatics. To complete the Masters project, you have to solve “a self-selected problem”. During this coursework you should examine an area of research that underlies (or may underlie) the problem you intend to solve for your project. Your proposal should include an overview and context of this area, together with a description of the appropriate methodologies or methods of enquiry you expect to use during the project. This should reference the bodies of knowledge, sources of information, and standards and professional organizations that you may have to draw on to complete the research part of your proposal.

  5. CMP3265 – Overview APPLICATION SUBJECT KNOWLEDGE PROFESSIONAL ISSUES RESEARCH • Informatics / IS / IT / Computer Science is moving very fast • The application of IT needs to be rooted in professionalism (no cowboys!)

  6. Why do I need to understand / do Research? • IT Fast moving area => • Must anticipate future developments • May need to adapt research results • May need to understand new standards, notations and languages • May want to contribute to research You may have to conduct research, or lead a research team, or evaluate someone else’s ..

  7. Recent Example of Research- led development => practice New semantic – web languages The international standard language called ‘OWL’ for encoding web-accessible ontologies. Research in areas Such as Description Logic OWL Need of Web-related industries W3C standard

  8. What is Research? . "Systematic investigation towards increasing the sum of knowledge" (Chambers 20th Century Dictionary) "an endeavor to discover new or collate old facts etc. by the scientific study of a subject or by a course of critical investigation." (The Concise Oxford Dictionary)

  9. Types of research • the scientist (computer science?) • the social scientist (information systems?) • the historian • the journalist • the politician’s assistant • industrial R & D

  10. Scientific Research Dominated by the Natural Sciences – 1. Make Observations (eg watch asteroids through a telescope) 2. Read accounts of similar work in scholarly journals (eg see what trajectory equations planets follow) 3. Form hypothesis (theory) using 1. and 2. (eg asteroids move in an elliptical fashion) 4. Test and evaluate hypothesis (measure the actual movement and check. Long term evaluation: What does the hypothesis predict? Is the prediction true?)

  11. Scientific Research - Relativity Eg Albert Einstein 1. From PAST observations the following were believed: (Special Principal of Relativity, Law of Light Propagation) 2. Read accounts of similar work in scholarly journals, use already accepted science (Albert used proven mathematical theorems and basic tensor analysis) 3. Form hypothesis (theory) using 1. and 2. (E=MC2, special relativity equations) 4. Test and evaluate hypothesis (what does the hypothesis predict? .. Black Holes etc)

  12. Example in Computing Research In computing, experiments are (generally) done by running programs and observing their results Example - My PhD thesis: ‘machine learning’ can improve the performance of intelligent programs • I wrote an automated planning program called FM, which automatically generated solutions to planning problems. • then I designed a ‘learning algorithm’ that learned from analyzing the solutions of planning problems. • then I implemented the learning algorithm within FM, • then I tested it by getting FM to solve randomly generated planning problems, and let the learning algorithm learn ‘heuristics’ from the solution trace. • I observed that FM’s plan generation speed increased dramatically with the addition of the learned heuristics. NB Experiments must be such that they can be independently re-constructed and validated.

  13. Types of (computing) research project • Compare methods • Discover / invent new Method or Algorithm • Discover / prove new invariant / Law / theory • Extend / repair an existing method • Formalise / make precise an existing theory Research can be “ground breaking” or “bump on a log”

  14. The form of research projects MAIN PARTS: Aim/Objectives Method Evaluation We will look at Aims/Objectives today, and method and evaluation tomorrow

  15. The form of research projects Research projects aims and objectives must be • CLEAR (there should be a way to show that objectives have been met) • SIGNIFICANT and TIMELY in that they deliver a valuable result (that’s currently needed) • ORIGINAL in that they are doing something new • FEASIBLE in that they can be achieved by specified resources

  16. BREAK…. ..and do Exercise: write down the aims/objectives of ANY (imagined) IT research project you can think of. Try to make one which is clear, significant and original.

  17. Example of research project “We are going to show that Object-oriented databases are better than Relational Databases” • ? Clear • ? Significant/timely • ? Original • ? Feasible

  18. Example of research project “We are going to show that Object-oriented databases are better than Relational Databases” • ? Clear: No - ‘Better’ - too vague - NOT MEASURABLE • ? Significant/timely • ? Original • ? Feasible

  19. Example of research project “We are going to show that Object-oriented databases are better than Relational Databases” • ? Clear: No - ‘Better’ - too vague - NOT MEASURABLE • ? Significant/timely: Yes, maybe – many industries are considering changing to OODB’s as they are more compatible with OOPLs so some kind of answer to this question would be of value • ? Original: • ? Feasible

  20. Example of research project “We are going to show that Object-oriented databases are better than Relational Databases” • ? Clear: No - ‘Better’ - too vague - NOT MEASURABLE • ? Significant/timely: Yes, maybe – many industries are considering changing to OODB’s as they are more compatible with OOPLs so some kind of answer to this question would be of value • ? Original: we would have to consult the literature to check • ? Feasible:

  21. Example of research project “We are going to show that Object-oriented databases are better than Relational Databases” • ? Clear: No - ‘Better’ - too vague - NOT MEASURABLE • ? Significant/timely: Yes, maybe – many industries are considering changing to OODB’s as they are more compatible with OOPLs so some kind of answer to this question would be of value • ? Original: we would have to consult the literature to check • ? Feasible: – too vague to comment

  22. Better Example of research project • Aim: OODBs are an advance on RDB • Objective 1: We are going to show that using Object-oriented databases leads to more reliable implementations than using Relational Databases • ? Clear – better than 1st attempt. Reliability is measurable ( = mean time to failure) but the ‘using .. leads to’ is still vague • ? narrower aims so less significant • ? Feasible – difficult to ‘prove’ as it involves the use of teams of people

  23. Example of research project “We are going to discover / invent a program that can identify all the bugs in any given program” • ? Clear • ? Significant/timely • ? Original • ? Feasible

  24. Example of research project “We are going to discover a program that can calculate the number of bugs in any given program” • ? Clear - yes • ? Significant/timely - very • ? Original – no one else has done this • ? Feasible – absolutely not!

  25. Conclusions • As a computing/IT professional you should be able to access, understand and evaluate research. • They are many forms of scientific research • Research proposals should contain Aims + Objectives, a proposal method, and a route to evaluation. • Aims + Objectives should be clear and measurable, significant, timely and original. • Tomorrow – we will look at research methods and evaluation

  26. Portfolio Exercise • Look for the description of a large computing research project on the web (eg there are many such EU Framework 6 projects). • Identify the project’s aims and objectives. • Comment on whether you think they are clear, significant, timely, original, feasible
