Research Problem: Problem
finding, Literature Survey,
Publishing / Patenting
• Problem solving versus problem finding
• Formulation of a problem
• Types and attributes of research problems
• Sources of research problems
• Literature survey
• Papers and patents

Finding a problem
• is harder but more essential than solving it
• is as much a student’s responsibility as that of the guide.
A problem must spring from a researcher’s mind like a
plant springing from its own seed.
Research Problem: Problem Solving vs
Problem Finding
Students are used to well-defined problems having a single solution. They are
uncomfortable with ill-defined problems.

A just-found problem is ill-defined. Its formulation as a well-defined
problem is an iterative process, which may get completed only after
thesis writing !!
Research Problem: Problem Solving vs
Problem Finding

Do not worry too much whether your problem is the best
one to study. Once you go deep, any problem becomes
interesting. The important thing is to get started.
Research Problem: Problem Finding
Problem finding is an autocatalytic reaction !

Research Problem: Getting Started
Ideas strike by chance, but only to a prepared mind
Only a prepared mind can follow a lead opened by an observation
which is too insignificant to attract the attention of a common man.
To prepare the mind, do the following cyclically
- Reading
- Implementing someone else's work
- Thinking (in partial ignorance)

Research Problem: Steps
in finding a problem
• Identify an area of interest
• Gather information looking for gaps
• Formulate a hypothesis

Research Problem:
Formulation of a hypothesis
General statement

Resolution of ambiguities

Thinking and rephrasing

Clear, concise, manageable statement

Research Problem:
Formulation of a hypothesis
Example 2
1. Average learners are less nervous because they are average.
2. Students possessing average intelligence are less nervous than others.
3. Students possessing average intelligence have fewer symptoms of
abnormal behavior than those having very high or very low intelligence.

Research Problem: Types of
Research Problems
 Theory building or modeling of experimental data
 Collecting experimental data to prove or disprove
a hypothesis
 Innovation or invention of a new device.

Research Problem: Attributes of
Research Problems
 Difficulty
 Value or usefulness
 Originality
 Is it interesting (does it deny
commonly held assumptions ?)
 Significance / impact (all the above and more)
 Cost / equipment / cooperation

 “Future work” sections in thesis and papers
 Interaction: discussion, answering doubts,
teaching, explaining
 Comparison of different approaches by some
objective measures of efficiency or accuracy
 Harmful simplifications or arbitrary choices in
a paper - try something different
 Derivation of simple closed-form solution
Research Problem: Sources of
Research Problems

 Identify all variables and alternatives of a situation
to see which have not been explored.
 Study existing systems / procedures and note what
they do badly at.
 Implement someone else's work yourself and see
the many problems out there to work on.
 Combine and reorganize existing knowledge
structures
Research Problem: Sources of
Research Problems

Research Problem:
LITERATURE SURVEY
• Why literature survey
• What to read
• How much to read
• How to read
• Note taking

• To know sufficiently enough to identify gaps and inconsistencies in an area.
• To know the views and interest of others in a topic.
• To know and establish contact with people who may be interested your
work.
• To know if others have already done what you want
to do.
• To integrate and compare various ideas on a topic.
• To get hints on how to tackle your problem.
Research Problem: Why
Literature Survey

Primary sources (new information)
• Journal papers
• Patents
• Research reports
• Conference proceedings
• Theses
Research Problem: What to read

Other sources (old information)
• Indexing and abstracting services
• Review articles, history of the problem
• Books
Research Problem: What to read

• Start with articles published recently and go back to about 5 years earlier.
• Read and think alternately. Don't spend eternity on literature survey, start
doing your own thinking early. One has to start in a state of partial
ignorance, and this has an advantage that you are free from prejudice
which suppresses new ways of doing things.
• Reading should continue throughout the research process
Research Problem: How much to
read

Research Problem: How to read
 Scan to get an overview.
 Read the title, abstract, conclusions, and the figures.
 Highlight anything that has attracted your attention.
Then read in detail.
 One can read word by word, line by line, paragraph by
paragraph, chapter by chapter, even book by book !!

Research Problem: Note Taking
 The purpose of notes is to try and keep information to
assist memory.
 Notes are memory maps. Branching notes with sketches,
remarks, key words etc. may be more effective than the
paragraph-wise compiled material.
 Notes are developed alongside the learning process, not
after the process.

 Leave liberal margins for future additions and remarks.
 Every new topic should start on a separate page.
 Notes must be updated by reading more and more.
 Notes taken for the same subject by different persons
may differ appreciably, because the subject-matter
understood by the note-taker is integrated with the
existing knowledge and then jotted down as sketchy
notes.

 Include all details of a publication, on which you are
taking notes, as succinctly as possible.

The Research Process
Steps
1. Identify a research problem broadly in a general area of
interest.
2. (a) Do background course work to acquire breadth.
(b) Review basic concepts and theories.
(c) Make a comprehensive review of relevant literature.

The Research Process (contd.)
3. Define the research problem of the thesis.
4. Formulate a hypothesis (if appropriate).
5. Plan the mode of execution. (Work could
be experimental or theoretical or both.)
6. Deliver a seminar talk.

For experimental work :
7. Design and build experimental set-up.
8. Do preliminary testing to check set-up.
9. Collect data in a systematic manner by
varying the independent parameters.

For theoretical work :
7. Model the situation and set up the
governing equations with constraints.
8. Solve the equations ( either analytically or
numerically).
9. Obtain results by systematically varying
the independent parameters.

Research Process: The Issue of
Plagiarism
Plagiarism – Using someone else’s research
work in the form of ideas, results or words
and passing it off as one’s own work by
not giving credit to the original work.
Plagiarism is unethical and incorrect, but is
widespread.

 To philosophers and thinkers, research may mean the
outlet for new ideas and insights;
 To scientists, research may mean more and more
innovations and discoveries;
 To Analysts and Intellectuals, research may mean the
generalizations of new theories;
 To literary men and women, research may mean the
development of new styles and creative work;
 To those students who are to write a master’s or Ph.D.
thesis, research may mean a careerism or a way to attain
a high position in the social structure;
 To some professionals in research methodology, research
may mean a source of livelihood.

Characteristics of research
 Research originates with a question or doubt.
 Research is a highly intellectual activity which is
not every body’s cup of tea.
 Research inculcates scientific, creative and
inductive thinking and promotes the
development of logical habits of thing among
human beings.
 All progress is born of research because
Research is directly proportional to Development
(R & D Concept).

Knowledge – The FOUNTAIN of
research
 Creation, Verification, Generation and Discovery of
Knowledge is the ultimate goal of Research process.
Knowledge perishes and sometimes becomes
obsolete. Research is the only tool by which we can
update and maintain our knowledge banks/resources.
Knowledge has been recognized as the key driving
force in the 21st century and India’s ability to emerge
as a globally competitive player will substantially
depend on its knowledge resources. To foster
generational change, a systemic transformation is
required that seeks to address the concerns of the
entire knowledge spectrum (National Knowledge
Commission).

HOW TO READ RESEARCH
1. Locate and read a few articles from within a field
you are comfortable with.
2. Read studies that are of interest to you.
3. Read the abstract first.
4. Identify the research question and objectives.
5. Why did the researcher(s) choose a particular
setting or sample?
6.What were the methods chosen to collect data?
7.What were the most important findings?
8. Do not be over-concerned with statistical
analysis.
9. Be critical but objective.

Assumption – you are familiar with topic
Pre-requisite to reading a technical research paper:
You are “somewhat” familiar with the broad idea
Else
Better to first become somewhat familiar
Read a textbook for fundamental concepts
Take a course
Go through tutorials
Read a survey / review paper

Stage 3
Evaluate the
details

The Scientific Research Paper is a
Peculiar Piece of Writing
 Highly structured, almost predictable headings
 Every item in paper exists for a reason, nothing merely for
cosmetic reasons
 Each part connected with other parts
 sentence1  sentence 2, paragraph1 paragraph2,
section1 section2
 Sequence is important
 Figure  text
 Yet, space is highly constrained
