Discusses the key word shallowly the computation rule
The optimization will involve the key word, but many friends understand the key word very much, these regarding the search key word computation’s understanding, will develop further your optimized mentality.
Originally I have spoken anything am the key word, this I said the search regarding the key word computation.
First confirms three factors:
[1]web (network, said accurately actual was search already included page’s set)
[2]site (website set, what refers to is in snapshot, search includes page’s set)
[3]page (homepage)
The first step computation:
Because the search is the homepage sorting computation, i.e. the bright this page is some key word computation foundation and the main source, good, which this page regarding this key word’s computation is first step, first aims at this page of confirmation key word. And gets up early simply has based on 2 Yuan Boolean logical computations and so on.
The second step computation:
Because most direct is in your station the homepage set, generally a subject (key word) will use a station, or many pages will describe, like this will search will participation yours website set this page’s key word computation, regarding the link node computation, in the station the pr computation as well as idf and so on computation will be this meaning. Expansion to this page of this words and expressions relevant computation.
The third step computation:
Because in the search, words and expressions is only a member, from the words and expressions may retrieve your homepage (are also reverse index rule), perhaps this words and expressions are also on the Internet many homepages in the description, therefore in an information theory bit law, explained that if must obtain this page this words and expressions accurate sorting result to let the web data in the possible scope participate in the computation.
Simultaneously here has also given the optimized decision mentality, more is many people the words and expressions which does, the difficulty is being bigger, to is not the computation impediment, but is this word weight is not high, must therefore adopt effectively, has in view of the means does, the high heat degree’s words and expressions also did not have the great difficulty like this again.
My high heat degree words and expressions’ optimization is based on this mentality. Certainly many detail’s place each people will have do not use the different idea and the procedure.
