ASSIGNMENT

COMPARISON BETWEEN 2 I R MODEL
1,Firsst model is complicated than second model
2,In second model pop of doc&sel doc are thereas input .but in 2 model only text obj is there
3,In 1 mod conc anal &trans are the 2steps ussed for indexing .But in 2 mod only indexed obje are taken
along with repr steps
4,In 1mod out put steps are similar to the input(usr put a request ).samethings are happened in 2 mod
( a user put a query )
5, In 1mod it searches for users needed infn in its indexing rec ,In 2 mod it compare the users query with
its indexed obj
6,In 1 mod search strategies indexing records system vocccabulary .data base of doc repre given us the
more infn about the I R process ,Than in 2 mod , because 2 mod didnot consist to much of component
in its model
7,In 1 mod users can accessthe infn directly through doc repre steps ,If he knew the search strategies ,but
this is not shown in 2 mod
8,In 2 mod it can take out the infn without comparison steps &it also can evaluate &put infn to the user ,
these steps are not shown in 1 mod
9,Both mod are holds good to any application or example of I R system
10,Both mod are similar except some points mentioned above
NOTE:
Here 1mod is "Major func of infn services" & 2 mod is "Simple flow of retre system"
