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

Search the Internet has an important roleSearch the Internet has an important role

Engineering Research Methodology -- Kahani 11

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

Searching the web

Search engines How do they work?

1. Gathering information from the web (offline)

2. Indexing documents

3. Responding to the queryies

4. 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, …

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

Engineering Research Methodology -- Kahani 21

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
