Step 3), judges that whether current context is less than the minimum length that user arranges, and if so, expands current context;
Step 4), judges that whether current context is greater than the maximum length that user arranges, and if so, cuts down current context;
Step 5), shares the context of generation.
As a kind of self-adaptation of the present invention, supply the further prioritization scheme of the contextual method of keyword, the detailed step of described step 3) is as follows:
Step 3.1), the position according to keyword in paragraph arranges the dimension of current context, and keyword, when the first half of current context, arranges dimension backward, when the latter half of current context, dimension is set forward;
Step 3.2), dimension is backward time, and the first character after current context starts to read successively backward, and judge whether institute's reading character is the punctuation mark in expansion punctuate table, and if so, current context is expanded to herein, if not, continue to read, until document finishes;
Step 3.3), dimension is forward time, and the first character before current context starts to read forward successively, and judge whether institute's reading character is the punctuation mark in expansion punctuate table, and if so, current context is expanded to herein, if not, continue to read, until document starts;
Step 3.4), after each expansion, all need dimension to be next time set to contrary direction, and judge whether current context length is less than the minimum length that user arranges, if, continue expansion, until contextual length is greater than the minimum length value that user sets, or entire chapter document is all in context.
As a kind of self-adaptation of the present invention, supply the further prioritization scheme of the contextual method of keyword, the detailed step of described step 4) is as follows:
Step 4.1), the position according to keyword in current context arranges reduction direction, when the first half of keyword at current context, arranges and cuts down direction forward, when the latter half of keyword at current context, arranges and cuts down direction backward;
Step 4.2), cut down direction forward time, from last character of current context, start to read forward successively, often read a character, judge this character and whether word that the character that read in forms belongs to general word and phrase database, if belonged to, this character and the character that read in are rejected from current context, if do not belonged to, continue to read character late, until become the word in dictionary general word and phrase database or surpass 10 words deleted;
Step 4.3) cut down direction backward time, from the first character of current context, start to read backward successively, often read a character, whether the word that the character that judges this character and read in before forms belongs to general word and phrase database, if belonged to, this character and the character that read in are before rejected from current context, if do not belonged to, continue to read character late, until become the word in dictionary general word and phrase database or surpass 10 words deleted;
Step 4.4), after each reduction, all need to cut down direction next time and be set to contrary direction, and judge whether current context length is still greater than the maximum length that user sets, if so, continue to cut down, until contextual length is less than the maximum length that user sets.
As a kind of self-adaptation of the present invention, supply the further prioritization scheme of the contextual method of keyword, described expansion punctuate table comprises following punctuation mark: English fullstop ". ", Chinese fullstop ".", branch "; ", English comma, ", Chinese comma, ", pause mark ", ", question mark "? ", exclamation mark "! ", backslash " ".
As a kind of self-adaptation of the present invention, supply the further prioritization scheme of the contextual method of keyword, described general word and phrase database adopts the Chinese vocabulary bank of the search engine of increasing income.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
1. provide a kind of self-adaptation to supply the contextual method of keyword, can represent to user the semantic scene of keyword.
2. the keyword that the length range that can arrange according to user is user adds corresponding context.
Embodiment
