IntroductionIntroduction

• Internet growth

• Information Explosion

• Search Engines– Definition

– Key to information treasure

– Role of a library catalog

Slide 3

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)

Slide 4

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
