The time format one that the present embodiment proposes and the summary of time format two to the common expression-form of time propose, and common temporal expressions form can be such as: " on August 12nd, 2013 ", " August 12 ", " No. 12 ", " August 12 ", " tomorrow ", " today ", " today ", " tomorrow ", " day after tomorrow ", " day before yesterday ", " nearly one week ", " a nearly week ", " last week ", " last month ", " next month ", " nearly one month ", " first 3 days ", " upper 1 week " and " first three sky " etc.
Wherein, time format one comprises three parts, wherein Part I is mainly: the present, yesterday, bright, front, near, upper, rear and large after in arbitrary, Part II is mainly numeral, and Part III is mainly: day, sky, the moon, week, year, number, arbitrary in week and week, wherein Part II can be default, such as: the expression formula of some time is " first three sky ", and now three parts all have, and the expression formula of some time is " day before yesterday ", now lack Part II, but this allows.
Wherein, time format two is primarily of Part IV and Part V composition, and wherein Part IV be digital, and Part V is: the moon, day, year and number in arbitrary, its common form of expression is such as " 02 year ", " No. 25 ", " August ", " 13 days ", etc.
The present embodiment, for the information of user's input, identify the temporal information of wherein mating with time format one or time format two, and according to this temporal information recognized, scope initialized search time is offset or is done the replacement of element of time, final scope search time is determined with this, this kind of mode, do not need user according to set form input time in temporal information frame, user's select time from selection of time frame is not needed yet, user only needs to input containing the search word of temporal information and passable according to normal temporal expressions mode, such as directly input " price of nearly one week egg ", therefore the operation complexity of user can be reduced, improve the Experience Degree of user, also corresponding Webpage search interface can be made more succinct simultaneously.
Please refer to Fig. 2, be provided by the invention be applied in search engine search time range determining method the schematic flow sheet of the second embodiment, it comprises:
The information of step S21, reception user input, and initialization scope search time.
Wherein, the information of user's input can be such as " June in 2013 Chinese cabbage on the 5th price, today watermelon price; the preferential activity of tomorrow; the news of last week, which the work of nearly three days has, the house transaction situation of nearly a year " etc. the search type containing temporal information.
Wherein, during initialization scope search time, can by initialization today scope search time, such as: when today is on August 12nd, 2013, then scope is initialization time: start(starts)=on August 12nd, 2013 00:00:00, end(terminate)=on August 12nd, 2013 23:59:59.
The temporal information of time format one is met in the information received in step S22, identification step S21.
Step S23, determine to recognize meet time migration parameter corresponding to each several part in the temporal information of time format one.
Step S24, time migration parameter corresponding for each several part determined to be multiplied as final time offset.
Step S25, final time offset is adopted to offset described initialized time search scope.
Wherein, the corresponding time migration parameter of the keyword of every part in time format one, time migration parameter is in units of sky, and adopt the form of time migration Parameter Mapping table to store keyword and time migration parameter, wherein time migration Parameter Mapping table can be as shown in Table 1.
Table one:
In Table 1, "-" number represents (past) skew backward, and "+" number represents (future) skew forward.Such as "-1 " represents skew backward one day, i.e. yesterday, "+1 " represents biased forwards one day, i.e. tomorrow, the off-set value that " middle without any numeral " is corresponding when being hypodactylia Part II, the off-set value that such as " front " was corresponding in " day before yesterday " is "-2 ", and the off-set value that in " first three sky ", " front " is corresponding is "-1 ".
Wherein, after determining time migration parameter corresponding to each several part, the result that each several part is multiplied by the present embodiment is as final time offset, such as: in " today ", the time migration parameter of Part I and Part III difference correspondence is " 0 " and " 1 ", the final time offset that then " today " is corresponding is 0*1=0, the time migration parameter that again such as in " nearly 10 days ", Part I " closely " is corresponding is "-1 ", middle continuous print numeral integrally, the time migration parameter of its correspondence is " 10 ", Part III " my god " corresponding time migration parameter is 1, therefore the time offset that " nearly 10 days " are corresponding is "-1*10*1=-10 ".
Enumerate the time offset that some common temporal expressions modes are corresponding below again, such as:
" first three sky "=-1*3*1
" yesterday "=-1*1
" a upper week "=-1*1*1*7
" tomorrow "=1*1
" nearly one month "=-1*1*1*30
" nearly ten days "=-1*10*1
" first 2 days "=-1*2*1
Wherein, after final time offset is determined, this time offset is adopted daily to do time migration to initialized time search scope, time migration can be done to the initial time (start) in initialized time search scope herein, or all can do time migration to initial time (start) and end time (end).
