WHAT IS ALREADY EXISTING
• Google personalizes if you are logged in.
• Can start personalizing only when your session starts to a search engine(SE).
• How much time a user is browsing a particular page can’t be deduced.
• Page relevance criteria is based only on those WebPages that you access using SE.
WHAT IS THE SOLUTION!!!
• It is the Browser that knows about user’s intentions.
• So better shift the focus from server side to client side
• Keep track of all the web pages visited and rank them on the basis of their relevance
• Use criteria like Browse time & Download to give them relevance
• After making a set of such pages extract keywords from them.
KEYWORDS ????????
• Words of high frequency.
• Words in title, subtitle, meta tags and in the starting paragraph of page.
• Should not be STOP words i.e. words like “a, an, the” which are of high frequency.
CATEGORY DEDUCTION
• A model that will give category classification such that we have C1, C2, C3, C4 ……
• C1, C2, C3, C4 should span the entire web search query possibilities.
• C1, C2, C3, C4 should be independent.
• Apple – computers/hardware or living/food & cooking
• Mouse - computers/hardware or wildlife/nature
Ex .
CATEGORY DEDUCTION (CONTD.)
• So once keywords are made deduce all possible categories for them.
• Now take intersection of them i.e. pick out common from them.
• if we take intersection of Mouse and Apple we get – computers/hardware
• Now we know what user intentions actually are
Ex.
NEXT TIME WHEN USER GOES TO GOOGLE….
• Type query
• Results come to browser
• Give an option to rank the result according to user intentions
• If yes, send the retrieved result + category deduced earlier to the server hosted
• Server will re-rank them according to the category
• This re-ranked page is what user will see eventually.
