Topics

  • Research Methodologies

  • Research thru Internet


What is Research?

  • The systematicinvestigation into and study of materials, sources, etc, in order to establish facts and reach new conclusions.

  • An endeavour to discovernew or collate old facts etc by the scientific study of a subject or by a course of critical investigation


Research Methodologies

  • Scientific method

  • Engineering method

  • Empirical method

  • Analytical method


Scientific method

Observe real world

Propose a model or theory

of some real world phenomena

Measure and analyze

above

Validate hypotheses of the

model or theory

If possible, repeat


Engineering method

Observe existing solutions

Propose better solutions

Build or develop better

solution

Measure, analyze, and

evaluate

Repeat until no further improvements are possible


Empirical method

Propose a model

Develop statistical or other

basis for the model

Apply to case studies

Measure and analyze

Validate and then repeat


Analytical method

Propose a formal theory or set of

axioms

Develop a theory

Derive results

If possible, compare with

empirical observations

Refine theory if necessary


Different Types of Research

Fundamental Research

Applied Research

Developmental Research


Search the Internet has an important role

Activities

  • Find your Topic

  • Do a review of the literature

  • Formulate your thesis

  • Defend your thesis title

  • Develop your solution

  • Validate and compare your answer

  • Write up

  • Defend your thesis


Find Research Topic

  • Check for conference CFP and conference programs

  • Check Other universities research topics

  • Test your topic

    • too much information --- narrow your topic

    • too little information -- use synonyms, hypernyms


Literature Review

  • FIND BACKGROUND INFORMATION

    • WikiPedia

  • USE CATALOGS TO FIND BOOKS AND MEDIA

  • USE INTERNET TO FIND PERIODICAL ARTICLES

  • READ & EVALUATE WHAT YOU FIND

  • CITE WHAT YOU FIND USING A STANDARD FORMAT


Search Library

  • Connect to the University Library

    • http://c-library.um.ac.ir/

  • Use Guides to learn how to use the system

  • Click on جستجو وتمديد منابع كتابخانه

    • http://clibrary.um.ac.ir/simwebclt/WebAccess/SimwebPortal.dll


Searching the web

  • Search engines

  • How do they work?

    • Gathering information from the web (offline)

    • Indexing documents

    • Responding to the queryies

    • Rendering the findings

  • Different Search engines, different startegies

  • General purpose vs. special purpose Search engines

  • Use Advanced Search for more options

  • Be hunter not searcher


The Invisible Web

  • What is it?

    • Part of the web that can’t be indexed by search engines

  • The invisible web is now (mostly) visible

    • Search engines are now more powerful

      • Dynamic sites are indexed

      • Use hints from sites (eg. robots.txt)

    • Databases have opened their doors for search engines

      • Eg. Sciendirect, IEEEexplore, ACM, …

    • Search engine have special tools

      • Eg. Google scholar, Google groups, Google Maps, …


Academic Search

  • CiteSeer

  • Scopus

  • Google Scholar


Citeseerhttp://citeseer.ist.psu.edu/


Scopus


Google Scholar


Evaluation & Comparison

  • Validate your results

    • Simulation methods & tools

    • Analyze your results

  • Use Scientific approaches

  • Compare with similar works

    • Redo their work

    • Compare with the published results

    • Use standard metrics (if exists)

  • Concentrate on both pros & cons


Write Up

  • Dr. Pour Reza will talk about it in details

  • Publish your results in conferences

    • Go for prestigious conferences

    • International Conferences costs you a lot

  • Publish the complete works in journals

    • Use only accredited journals (ISI)

    • Some journals charge you as well
