IntroductionIntroduction
• Internet growth
• Information Explosion
• Search Engines– Definition
– Key to information treasure
– Role of a library catalog

Need for a search strategyNeed for a search strategy
• Search engines have different working principle
• Ad hoc approach towards its use
• More time spent on search than necessary-frustration
• Necessity of systematic strategy to explore the net(WWWSS)

WWWSW( world wide web search WWWSW( world wide web search strategy(1)strategy(1)
• Based on classical IE approach of problem solving
• Characteristics of the strategy– Universally applicable
– Easy to understand
– Consistent and precise
– Reliable
– Stand the changes in technology

Slide 5
WWWSS( World wide web search WWWSS( World wide web search strategy)(2)strategy)(2)
• Steps in WWWSS– Study and understand the problem
• This requires knowledge on part of the user
– Define the requirements• Ask Who, How, When, Where, Why
questions– Identify proper tools and techniques
• Decide upon the type of search engine to choose
• Advanced, non advanced search• Decide upon the right level of search
topic

Slide 6
WWWSS( World wide web search WWWSS( World wide web search strategy)(3) strategy)(3)
– Design the search query• Selection of key words• Boolean, Wild cards, truncation and
synonyms
– Implement the search • Check for typo mistakes• Save the search results using bookmark• Use find on edit menu as a search tool to
find keyword on the page
– Refine the search accordingly• Change the search engine if required• Go back to step 2(Define requirements)

Simulating WWWSS(1)Simulating WWWSS(1)
• Peter a Design engineer
• Faced with the problem of driveshaft failure
• Takes help of web to seek information of possible solution

Slide 8
Simulating WWWSS(2)Simulating WWWSS(2)
• Study the problem– Peter being a design engineer has
knowledge to understand the problem. • Define the requirements
– Who\what: Driveshaft, Used in automobiles, quality, customers
– How : Wear of steel,spline joint, value engineering,Coefficient of friction- 0. 17
– Why : New design, save market reputation, wrong material
– When : During warranty period, Past 10 months,
– Where: Field failure, testing labs

Slide 9
Simulating WWWSS(3)Simulating WWWSS(3)
• Identify proper tools and techniques– Search engine type selected-Google– Advanced search- Being a specialized
topic– Level of search- Design basics
• Design of query– keywords
• quality,wear resistant, steel, material, value engineering, stress, wear resistant
– search engines math• Use Boolean provided by advanced
search

Slide 10
Simulating WWWSS(4)Simulating WWWSS(4)
• Implement the search – Type in keywords
• One by one • Combination• Uses appropriate time to deal with each
page. Discards dead links.– Surf through the links
• Learns about new composite material used for coating auto parts
– Get feed back• Try's to assimilate the information
– Store the search • Book marks the relevant pages related
with composite material

Slide 11
Simulating WWWSS(5) Simulating WWWSS(5)
• Refine the query– Accordingly reframe the query to suit the new
information – Repeats step 2 in strategy
i.e.Define requirements
• Solution obtained– Peter learns about a new low friction co-polymer
called Apticote, made of low friction copolymer coating which is wear resistant and applicable on steels. COF=0.18
– It is manufactured by Peoton Industries – He uses this information to study more about
copolymer materials– Prepares and presents the report to management

DrawbacksDrawbacks
• Not effective against spamming– Method used by page authors to trick the
search engines by typing in wrong words• Needs more efforts on part of the user
• Dependent on the search engine quality
• Results are not guaranteed

Slide 13
ConclusionConclusion
• Systematic strategy– Optimization of search process
• Uses more time on query formation and less time on actual browsing
• Less time spent– 70 % time saved
• More accurate results– Produced more relevant results
• A powerful approach for a powerful media
