Telephone number presentation mode complexity as can be seen from Table 1 in webpage is various, and the embodiment of the present invention is in order to improve electricity The discrimination for talking about number can be to original telephone number strings progress to be identified and phone number format in above step S102 Relevant pretreatment operation so that the target telephone number strings to be identified after pretreatment operation are protected as far as possible with phone number format It holds consistent.

In embodiments of the present invention, original telephone number strings to be identified are carried out and the relevant pretreatment of phone number format Operation may include according to the pre- cutting of separator, the identification of national area code and removal, the supplement of regional area code and duplicate removal etc..

First, according to separator carry out pre-cut timesharing, it may be determined that in original telephone number strings to be identified whether include Specified separator, if comprising specified separator in original telephone number strings to be identified, it is original according to the separator cutting Telephone number strings to be identified obtain at least two targets telephone number strings to be identified after cutting.If conversely, original electricity to be identified It talks about and does not include specified separator in number series, then without pre- slicing operation.Here, specified separator can be pause mark ", ", comma, ", branch "；", slash "/", back slash " ", montant " | " etc., the invention is not limited thereto.

For example, " 028-84876877,1380233318 ", determining should for the original telephone number strings to be identified in table 1 above Comprising specified separator (that is, comma, ") in original telephone number strings to be identified, according to this, separator ", " cutting is original waits for Identify telephone number strings, obtain the telephone number strings to be identified of the target after cutting be " 028-84876877 " and “1380233318”。

Secondly, the identification and removal of national area code.In existing telephone number, in order to distinguish the phone number of every country Code, it will usually national area code is added before telephone number.By taking the telephone number of China as an example, it will usually add 86 before telephone number To indicate to distinguish, however in without transnational make a phone call, there is no substantive use for national area code, thus can be carried out to it Removal is handled.

In embodiments of the present invention, after at least two targets telephone number strings to be identified after obtaining cutting, for Each target telephone number strings to be identified, determine whether the head of target telephone number strings to be identified has national area code, if It is the national area code for then removing target telephone number strings head to be identified.If conversely, target telephone number strings to be identified Head does not have national area code, then without going division operation.

In the step of carrying out pre- cutting according to separator, for the original electricity to be identified of pre- slicing operation need not be carried out Number series is talked about, then further determines that whether the head of the original telephone number strings to be identified has national area code, if so, removal The national area code on the original telephone number strings head to be identified.If conversely, the head of target telephone number strings to be identified does not have There is national area code, then without going division operation.

In an embodiment of the present invention, by taking Chinese area code 86 as an example, 86 common forms include+86,086,0086,86 Deng the embodiment of the present invention can judge whether 86 be Chinese area code according to remaining phone digit.For example, the original in table 1 above The telephone number strings to be identified that begin " 86-0877-70104577010457 " judge 86 for China according to remaining phone digit Number, then it is removed processing to 86, obtaining that treated, target telephone number strings to be identified are " 0877- 70104577010457 ", processing is also removed to 86 subsequent symbol "-" here.

Furthermore supplement is carried out at trivial number over the ground and when duplicate removal, can wait knowing to eliminating the target after national area code Other telephone number strings are analyzed, if the head that analysis obtains target telephone number strings to be identified has regional area code and this area Area code is imperfect, then supplementing this area's area code keeps it complete；If analyzing the head for obtaining target telephone number strings to be identified has Regional area code and the repetition of this area's area code, then carry out duplicate removal processing to this area's area code.

In the step of carrying out pre- cutting according to separator, for the original electricity to be identified of pre- slicing operation need not be carried out Number series is talked about, or in the step of national area code is identified and is removed, for the original of operation need not be removed Telephone number strings to be identified then further analyze the original telephone number strings to be identified, original are waited for if analysis obtains this Identify that the head of telephone number strings has regional area code and this area's area code is imperfect, then supplementing this area's area code keeps it complete； If the head that analysis obtains the original telephone number strings to be identified has regional area code and this area's area code repeats, to this area Area code carries out duplicate removal processing.

For example, the original telephone number strings " 286990619869906199 " to be identified in table 1 above, this original is waited knowing Other telephone number strings are analyzed, and the head for obtaining the original telephone number strings to be identified has regional area code and this area's area code Imperfect, then supplementing this area's area code keeps it complete, the target telephone number strings to be identified after obtaining regional area code supplement completely “0286990619869906199”。

For another example the original telephone number strings " 07710771324579718602365784 " to be identified in table 1 above, right The original telephone number strings to be identified are analyzed, obtain the original telephone number strings to be identified head have regional area code and This area area code repeats, then carries out duplicate removal processing to this area's area code, obtains the target phone to be identified removably after trivial number Number series " 0771324579718602365784 ".

In embodiments of the present invention, Chinese city, area, county's telephone number shown in table 1 above are grasped by pretreatment above After work, the target telephone number strings to be identified that obtain that treated, as shown in table 2.For pretreatment operation mentioned above, that is, Include according to the pre- cutting of separator, the identification of national area code and removal, the supplement of regional area code and duplicate removal etc., the present invention is simultaneously unlimited The sequencing that they are executed is made, in practical operation, can the sequencing that they are executed be set according to actual demand.Example Such as, one of arbitrary pretreatment operation is executed；Or first according to the pre- cutting of separator, then carries out the identification of national area code and go It removes, then carries out the supplement and duplicate removal of regional area code.For another example, the identification and removal of national area code are first carried out, area is then carried out The supplement and duplicate removal of area code, then according to the pre- cutting of separator.For another example first carrying out the identification and removal of national area code, then According to the pre- cutting of separator, supplement and duplicate removal of regional area code, etc. are then carried out.

Table 2

It should be noted that being carried out and phone number format phase to original telephone number strings to be identified in the embodiment of the present invention The pretreatment operation of pass, it is not limited to which above-mentioned several pretreatment modes can be in conjunction with the electricity of country variant in practical operation The characteristics of talking about number carries out corresponding pretreatment operation so that the target telephone number strings to be identified after pretreatment operation and phone Number format is consistent as far as possible, to improve the discrimination of telephone number.

After the step S102 target telephone number strings to be identified that obtain that treated, from initial position in step S104 It rises, target telephone number strings to be identified is divided according to the division rule for meeting phone number format, it is specified to obtain first The number series of digit, here can be in conjunction with the characteristics of different classes of telephone number (such as fixed-line telephone or mobile phone), choosing Corresponding division rule is taken to be divided.

At this point, the classification of the corresponding telephone number of number series of the first specified digit is identified in step S106, the present invention Embodiment provides a kind of optional scheme, in this scenario, it can be determined that whether the number series of the first specified digit meets The attributive character of one classification telephone number, if the attribute that the number series of the first specified digit meets first category telephone number is special Sign carries out completion to the number series of the first specified digit, obtains the first finger then according to the attributive character of first category telephone number Position the corresponding telephone number of number series of number.

Further, according to the attributive character of first category telephone number, completion is carried out to the number series of the first specified digit, The present invention provides a kind of optional schemes, that is, according to the attributive character of first category telephone number, determines to the first specific bit Several number series carries out the completion digit of completion, then from target telephone number strings to be identified, the first specified digit number Go here and there corresponding division position rise, intercept completion digit number.Later, the number of completion digit is attached to the first specified digit Number series end.

If the number series of the first specified digit is unsatisfactory for the attributive character of first category telephone number, new meet is chosen The division rule of phone number format re-starts division to target telephone number strings to be identified, obtains number of the second specified digit Sequence, and then judge whether the number series of the second specified digit meets the attributive character of second category telephone number, if so, root According to the attributive character of second category telephone number, completion is carried out to the number series of the second specified digit, obtains the second specified digit The corresponding telephone number of number series.

By taking Chinese city, area, county's telephone number as an example, when selection meets the division rule of Mobile Directory Number format, by In mobile phone include 11, according to its first 7 may determine that its correctness and affiliated area (here, mobile phone generally with 13,14,15,17,18 or 19 beginning can utilize mobile phone ownership table to judge preceding 7 correctness and affiliated area), because And target telephone number strings to be identified can be divided according to the division rule for meeting Mobile Directory Number format, obtain The number series that one specified digit is 7.

In addition, choose meet the division rule of fixed telephone number format when, due to fixed-line telephone be divided into official 400 or 10 number telephones, common 7 or 85 electricity of region phone and special official comprising 3 or 4 area codes of 800 beginnings Number is talked about, thus target telephone number strings to be identified can be drawn according to the division rule for meeting fixed telephone number format Point, obtain the number series that the first specified digit is 3,4 or 5.

For example, the original telephone number strings to be identified extracted from POI information are "+8613651464541,28- 84876877 ", to original telephone number progress to be identified and the relevant pretreatment operation of phone number format, it is followed successively by basis The pre- cutting of separator, the identification of national area code and removal, the identification of regional area code and supplement, then treated target electricity to be identified It is " 13651464541 " and " 028-84876877 " to talk about number series.Further, from initial position, according to meeting mobile phone The division rule of number format divides target telephone number strings to be identified " 13651464541 ", obtains the first specific bit The number series " 1365146 " that number is 7.Alternatively, from initial position, according to the division rule for meeting fixed telephone number format Target telephone number strings to be identified " 028-84876877 " are divided, the number series that the first specified digit is 3 is obtained “028”。

In an embodiment of the present invention, if the head of target telephone number strings to be identified has regional area code, from initial Position is risen, and according to the division rule for meeting Mobile Directory Number format, the target after regional area code to removing head is to be identified Telephone number strings are divided, and the number series that the first specified digit is 7 is obtained.For example, in table 2 above, target electricity to be identified It is " 0755-13651464541 " to talk about number series, and the head of target telephone number strings to be identified has regional area code " 0755 ", Then from initial position, according to the division rule for meeting Mobile Directory Number format, the mesh after regional area code to removing head It marks telephone number strings to be identified to be divided, obtains the number series " 1365146 " that the first specified digit is 7.

In an embodiment of the present invention, it can choose first and meet the division rule of Mobile Directory Number format target is waited for Identification telephone number strings are divided, and are obtained the number series that the first specified digit is 7, are judged the first specified digit for 7 Whether number series meets the attributive character of first category telephone number (that is, mobile phone), if so, according to first category phone The attributive character of number (that is, mobile phone), the number series for being 7 to the first specified digit carry out completion, it is specified to obtain first The corresponding telephone number of number series (that is, mobile phone) that digit is 7.

Still it is " original to this for+8613651464541,28-84876877 " with original telephone number strings to be identified Telephone number to be identified carry out with the relevant pretreatment operation of phone number format, such as delete national area code, obtain that treated Target telephone number strings to be identified are " 13651464541,28-84876877 ".Further, from initial position, according to meeting The division rule of Mobile Directory Number format divides target telephone number strings to be identified, and it is 7 to obtain the first specified digit The number series " 1365146 " of position, and then can identify that the number series that the first specified digit is 7 is corresponding according to step S106 Telephone number is mobile phone " 13651464541 ".

If the number series that the first specified digit is 7 is unsatisfactory for the attribute of first category telephone number (that is, mobile phone) Feature is then chosen and meets the division rule of fixed telephone number format and re-start division to target telephone number strings to be identified, It is 3,4 or 5 number series to obtain the second specified digit, and then judges the second specified digit for 3,4 or 5 numbers Whether sequence meets the attributive character of second category telephone number (that is, fixed-line telephone), if so, according to second category phone number The attributive character of code (that is, fixed-line telephone), the number series for being 3,4 or 5 to the second specified digit carry out completion, obtain the The corresponding telephone number of number series (that is, fixed-line telephone) that two specified digits are 3,4 or 5.

For example, in table 2 above, pre-processed to original telephone number strings " 286990619869906199 " to be identified After operation, it is " 0286990619869906199 " to obtain target telephone number strings to be identified, next from initial position, root Target telephone number strings to be identified are divided according to the division rule for meeting Mobile Directory Number format, obtain the first specific bit The number series that number is 7 is " 0286990 ", which is that 7 number series are unsatisfactory for first category telephone number The attributive character of (that is, mobile phone) then chooses the division rule for meeting fixed telephone number format to target phone to be identified Number series re-starts division, and it is " 028 " to obtain the number series that the second specified digit is 3, identifies that the second specified digit is 3 The corresponding telephone number of number series " 028 " of position is fixed-line telephone, respectively 7 " 0286990619 " or 8 s' “02869906198”。

In another embodiment of the invention, the division rule pair for meeting fixed telephone number format can also be chosen first Target telephone number strings to be identified are divided, and are obtained the number series that the first specified digit is 3,4 or 5, are judged first Specified digit is the attributive character whether 3,4 or 5 number series meet first category telephone number (that is, fixed-line telephone), It it is 3,4 or 5 to the first specified digit if so, according to the attributive character of first category telephone number (that is, fixed-line telephone) The number series of position carries out completion, obtains the corresponding telephone number of number series that the first specified digit is 3,4 or 5 (that is, solid Determine phone).
