Embodiment
Core concept of the present invention is: by web page title is carried out the participle analysis, obtain the title root, according to the number of times that each title root occurs, select the keyword of at least one many title root of occurrence number as described webpage in webpage.
Choose web page title, it is carried out the participle analysis, reason is that web page title generally is the summary to web page contents, often comprises front-page keyword.

Web page title is offered third party's participle software, carry out participle, obtain the web page title root;
This mode can effectively reduce root, improves search efficiency, such as, use participle software that " Chinese Government releases the intellectual property new measure " title is analyzed, can obtain roots such as Chinese Government, intellectual property, behave;
In embodiments of the present invention, can a counter be set for each web page title root, initial value is 0, is used for writing down the number of times that each web page title root occurs at webpage;
In other embodiment of the present invention, can adopt other counting mode, the number of times that record web page title root occurs in webpage does not influence the present invention and realizes;
The embodiment of the invention provides, and at netpage search web page title root, the method for the number of times that statistical web page title root occurs in webpage referring to Fig. 3, specifically comprises:
Step 301: from the webpage source file, read effective text data in the web data by the read-write order;
Wherein, comprise effective text data, label data, descriptive data in the webpage source file; Different data have different labels, and the present invention adopts regular expression or other character string processing method in reading process, remove the non-legible content in the webpage source file, obtain effective text data;
Wherein, those skilled in the art will know that described regular expression is a kind of character string processing method commonly used;
Wherein, described effective text data refers to be presented at the word content on the webpage, can be that Chinese also can be the literal of other Languages; Described label data and data of description refer to be used in the webpage source file order of the descriptive language of display web page content, with the html language is example, comprising: display text order＜p〉＜/p, display graphics order＜img, show form order＜table＜/table, show chained command＜ahref=
Www.sina.com.cnSina＜/a〉etc.;
Wherein, in the webpage during display text, can not use any markup language in the webpage source code, if need carry out attribute or locational setting to literal, then can use markup language, for example＜font size=1 () color=red hello＜/font show on the webpage be exactly font size be 10, red " hello " two words;
Step 302: a comparison string variable Str is set;
Step 303: from effective text data, read a character S
i,, Str=S is set as current web page content root
i, each the title root in Str and the tabulation is mated, if the title root of coupling is arranged, then the counter with this title root adds 1, represents that this title root has occurred in webpage once, after coupling is finished, presses the read-write order at S
iAfter append a character S
I+1, Str=S is set
iS
I+1, again with tabulation in each title root mate, if the match is successful, then with counter+1 of corresponding title root, the rest may be inferred, is appended in proper order by 15 characters by read-write until described web page contents root and forms, be i.e. Str=S
iS
I+1S
I+2... S
I+j, from S
iTo S
I+jBe 15 characters, then finish this step, enter step 304;
Step 304: read next effectively text data character S
I+1, judge that whether this character is last character in effective text data, if not, then repeating step 303, if then enter step 305;
Step 305: this character and title root are mated, if the match is successful, then the counter with corresponding title root adds 1, finishes whole flow process;
Wherein, in the step 303,, also can finish this step, enter step 304 if read non-legible characters such as punctuation mark, or space character;
