2. Slide 1 Use of Search Engines in CIM  2000 AbhijitHora USE OF SEARCH ENGINES IN CIM IEM 5303 Advanced manufacturing Systems design Term paper Abhijit Hora Masters student,IE & M OSU

3. Slide 2 Use of Search Engines in CIM  2000 AbhijitHora Introduction Internet growth Information Explosion Search Engines – Definition – Key to information treasure – Role of a library catalog

4. Slide 3 Use of Search Engines in CIM  2000 AbhijitHora Need 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)

5. Slide 4 Use of Search Engines in CIM  2000 AbhijitHora WWWSW( world wide web search 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

6. Slide 5 Use of Search Engines in CIM  2000 AbhijitHora WWWSS( World wide web search 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

7. Slide 6 Use of Search Engines in CIM  2000 AbhijitHora WWWSS( World wide web search 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)

8. Slide 7 Use of Search Engines in CIM  2000 AbhijitHora Simulating WWWSS(1) Peter a Design engineer Faced with the problem of driveshaft failure Takes help of web to seek information of possible solution

9. Slide 8 Use of Search Engines in CIM  2000 AbhijitHora 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

10. Slide 9 Use of Search Engines in CIM  2000 AbhijitHora 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

11. Slide 10 Use of Search Engines in CIM  2000 AbhijitHora 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

12. Slide 11 Use of Search Engines in CIM  2000 AbhijitHora 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

13. Slide 12 Use of Search Engines in CIM  2000 AbhijitHora Drawbacks 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

14. Slide 13 Use of Search Engines in CIM  2000 AbhijitHora Conclusion 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
