          What is Research?

 Thesystematic investigation into and
 study of materials, sources, etc, in
 order to establish facts and reach new
 conclusions.
 An endeavour to discover new or
 collate old facts etc by the scientific
 study of a subject or by a course of
 critical investigation

                 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

                                                                             14

                    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




                                                                              20
