Description
Technical field
The present invention relates to field of map search, more particularly to it is a kind of obtain between initialism and POI the method for corresponding relation and
Device.
Background technology
With continuing to develop for map search technology, people can be easily using the geography in map inquiry place needed for
Position and the geographical environment on periphery.Searched in map in plain technical field, the place needed for user is referred to as point of interest, also referred to as
POI（Point ofInterest abbreviation）；In cartographic information storehouse, the corresponding information of a POI point includes the complete of place
The information such as title, classification, longitude, latitude.When user searches for POI in map, the full name in place is inputted, then whois lookup is believed
There is the corresponding POI of the full name in breath, finally lookup result is exported to user, POI is searched by map search so as to realize
Function.
User is when using map search POI, and in order to input simplicity, the place name often inputted is not the ground
The full name of point, but the initialism in the place.And because the POI full name in POI storehouse are substantially the full name in place, so
Often inquired about less than POI when user inputs initialism.To solve this problem it is necessary to set contracting in terminal or server
Corresponding relation slightly between word and POI.User is when inputting initialism, and terminal or server first can be found in corresponding relation
Its corresponding POI query word can be inquired, is searched further according to the query word and obtains POI, looked into so as to realize by initialism
Look for POI function.Wherein, the query word can be POI full name or can inquire correspondence POI by current system

Embodiment
We preferred embodiment of the invention will be described in detail with reference to accompanying drawing below.Firstly it is pointed out that
The implication of term, words and the claim used in the present invention can not be only limited to its literal and common implication and go understanding,
The implication and concept for also including and then being consistent with the technology of the present invention, because we are as inventor, suitably be provided
The definition of term, so that the invention to us carries out most appropriate description.Therefore, this explanation and the configuration provided in accompanying drawing, only
It is the preferred embodiment of the present invention, rather than enumerates all technical characteristics of the present invention.We are it would be recognized that also various
Various kinds can replace the equivalent scheme or modification of our schemes.
In most cases, user can input more complete again when inputting initialism inquiry less than corresponding POI
Query word inquires about corresponding POI.Based on this application scenarios, basic thought of the invention is：User's search daily record is searched for, will
The query word in daily record in successful inquiring record is searched for as standard POI query words, a success before successfully being recorded with this
Failure record between record sets up initialism and mark as initialism, then according to the initialism obtained and standard POI query words
The corresponding relation of quasi- POI query words；Because the actual queries of a large number of users can reflect the change of geography information in map in time
And the difference of initialism used in user, by above-mentioned technical proposal, the corresponding relation between initialism and POI passes through user
The daily record that actual search POI is produced is obtained, it is possible to so that corresponding relation update can timely with the change of map and
The difference of user is synchronized, therefore, and the initialism of acquisition and POI corresponding relation are more accurate, so that user is according to this pair
Should be related to can just find the POI that user wants to look up exactly.
Below in conjunction with the accompanying drawings, the present invention is described in detail by specific embodiment and obtains corresponding relation between initialism and POI
The embodiment of method and apparatus.
Shown in Fig. 1 is the basic flow sheet that the present invention obtains the embodiment of the method one of corresponding relation between initialism and POI,
The present embodiment can specifically include：
Step 101, from user's search daily record, collect POI successful inquirings record, and the POI that current search is arrived is inquired about
Query word during success is recorded is defined as standard POI query words.
The embodiment of the present invention can apply to user first input breviary query word do not inquire correspondence POI it is then defeated again
Correspondence POI application scenarios can be inquired by entering more complete query word.User's input in above-mentioned scene is looked into order to realize
Ask word to be obtained, can be scanned for from user's search daily record.And for the ease of searching above-mentioned scene in day family search,
First it can search all inquiry POI in user's search daily record and successfully record, and can inquire POI's in successfully recording
Query word is used as standard POI query words.Standard POI query words in the embodiment of the present invention refer to look into POI data storehouse
Ask POI query word.
Step 102, current search to POI successful inquirings record recorded with the preceding POI successful inquirings that once search
Between exist POI inquiry failure record when, by POI inquire about failure record in query word be defined as initialism to be determined.
In order to inquire above-mentioned application scenarios in user's search daily record, after being recorded finding successful inquiring,
Currently successfully record and it is preceding once successfully record between search POI inquiry failure record, if it is present can primarily determine that
Meet above-mentioned application scenarios.Specifically, in order that scene searches more accurate, only can to record current success preceding one query
The situation for being recorded as failure record primarily determines that to meet above-mentioned application scenarios., can be with after primarily determining that and meeting application scenarios
It regard the POI query words inquired about in failure record as initialism to be determined.
Step 103, it is all contained in the standard POI query words in the individual character for constituting the initialism to be determined, and, respectively
Sequencing of the individual character in the initialism to be determined is identical with the sequencing occurred in the standard POI query words
When, the initialism to be determined is defined as to the initialism of the standard POI query words.
Due to the same POI that above-mentioned successful inquiring record may be to look for inquiry failure record, so,
Obtain corresponding relation before, it is necessary to further determine that the initialism to be determined whether the initialism of standard POI query words.It is logical
This step 103 is crossed, only the individual character in initialism to be determined is included in standard POI query words and each individual character is in two words
When the order of appearance is identical, it is the initialism of standard POI query words just to determine the initialism to be determined.For example, breviary to be determined
Word is " Beijing's science and engineering is big ", and standard POI query words are " Beijing Institute of Technology ", are not included due to having in initialism to be determined
Individual character " city " in standard POI query words, therefore initialism to be determined will be not determined as the breviary of standard POI query words
Word.For another example, initialism to be determined is " institute of electronics 20 ", and standard POI query words are " research institute of electronics technology 12 ", although treated
Determine that all individual characters of initialism are included in standard POI query words, but individual character " two " and " ten " are in initialism to be determined
It is opposite with the composition order in standard POI query words, therefore the initialism to be determined will be not determined as standard POI inquiries
The initialism of word.For another example initialism to be determined is " Beijing Normal University ", and standard POI query words are " Beijing Normal University ", due to breviary
The individual character of word is all contained in standard POI query words, and sequencing of the individual character in initialism with standard POI query words
Sequencing is identical, hence, it can be determined that " Beijing Normal University " is the initialism of " Beijing Normal University ".
Step 104, the corresponding relation for setting up the initialism and the standard POI query words, and by the initialism with
The corresponding relation of standard POI query words is defined as corresponding relation between initialism and POI.
The mode of initialism and the corresponding relation of standard POI query words is set up, can be that initialism and corresponding POI is complete
Claim composition one mapping set, such as { Beijing University, Peking University }.
Due to can inquire corresponding POI in existing system by standard POI query words, so, user
Actually enter initialism by from initialism with determining corresponding standard POI query words in the corresponding relation of standard POI query words
POI can be just inquired, therefore, the corresponding relation of initialism and standard POI query words contracting can be defined as in the present embodiment
Corresponding relation slightly between word and POI.
In addition, searching for daily record by user, multiple corresponding relations can typically be obtained using the technical scheme of the present embodiment,
In these corresponding relations, standard POI query word only can set up corresponding relation with an initialism, can also with it is multiple
Different initialisms set up corresponding relation respectively.Because the title of an address can may have several different conventional initialisms, and
These initialisms have user using, therefore user's search daily record all have recorded the inquiry using these initialisms as query word
Record, such a standard POI query words may appear in multiple corresponding relations, and at this moment, standard POI query words are just right
Multiple different initialisms are answered.
It should be noted that after step 104 performs completion, corresponding relation has been acquired between initialism and POI.By
It is that the query word directly obtained in daily record is searched for from user is used as the initialism and standard in corresponding relation in step 104
POI query words, therefore, this two word may be troublesome, with the participle repeated, is so unfavorable for saving the storage of corresponding relation
Calling again to corresponding relation when space and other users lookup.Therefore, to solve the above problems, can be with the present embodiment
After step 104, including step as shown in Figure 2：
Step 201, participle is carried out to the initialism and the standard POI query words, obtain the set of initialism participle and
Standard POI query word participle set；
Step 202, determine identical point in the initialism participle set and the standard POI query words participle set
Word, and respectively by the identical participle determined from the initialism participle set and the standard POI query words participle set
Delete；
Step 203, the participle that will retain in the initialism participle set, successively according to each participle in the initialism
Sequencing, be combined into amendment initialism；The participle that will retain in the standard POI query words participle set, successively according to
Sequencing of each participle in the standard POI query words, is combined into amendment standard POI query words；
Step 204, the corresponding relation for setting up the amendment initialism and the amendment standard POI query words, and with described
Correct initialism and correct corresponding relation between the corresponding relation renewal initialism of standard POI query words and POI.
Wherein, can use existing participle when carrying out participle to initialism and standard POI query words in step 201
Device carries out participle to initialism and standard POI query words, but in order to which participle is more accurate, also needs to adjust existing segmenter
It is whole.For example, when carrying out participle to corresponding relation { nine fort passenger stations, nine fort passenger transport central stations }, being divided into { nine according to existing segmenter
Fort, passenger traffic is stood } and { nine forts, passenger traffic, center, stand } it is obviously improper, need to adjust existing segmenter in the present embodiment, will be single
The end participle of word merges with previous participle, so that word segmentation result is { nine forts, passenger station } and { nine forts, passenger transport central station }.
, it is necessary to which adjusting existing segmenter makes when for another example, to corresponding relation { Beijing CA center, Beijing International shipping center } progress participle
Word segmentation result is { Beijing, CA center } and { Beijing, International shipping center }.
Fig. 2 embodiment is illustrated with an example below.In this example, it is determined that initialism be with corresponding relation
{ row, Changping Bank of China in Changping }, then the embodiment shown in Fig. 2 is specially：By initialism " row in Changping " and standard POI
Query word " Changping Bank of China " participle, forms initialism participle set { Changping, middle row } and standard POI query word participle set
{ Changping, China, bank }；Delete the participle " Changping " all included in two set；According to standard POI query words " in Changping
The group word order of bank of state ", remaining participle separately constitutes amendment initialism " middle row " and amendment standard POI during two are gathered
Query word " Bank of China "；Corresponding relation between initialism and POI is updated to { middle row, Bank of China }.
It should be noted that determining the corresponding pass between initialism and standard POI query words by the embodiment shown in Fig. 2
After system, initialism and standard POI query words is actually set only to retain the content of core, and the title of specified place all can be by
It is simplified or deleted, that is, it is not that can inquire correspondence POI standard POI query words that initialism is corresponding in corresponding relation,
But the simplification word of standard POI query words.And user specifically search specified place POI when, the contracting that user can be inputted
Slightly word also does above-mentioned word segmentation processing, and corresponding amendment standard POI is searched in corresponding relation using the amendment initialism of formation
Query word, then the participle that participle simplifies or deletes is rejoined to the amendment standard POI query words found, finally obtained with this
Standard POI query words go to search the POI in map again.For example, { row, Changping Bank of China in Changping } this corresponding relation passes through
After embodiment processing shown in Fig. 2, it is updated to { middle row, Bank of China }, and when user inputs " row in Changping "
Wait, first to input word participle into { Changping, middle row }, then to be got to " middle row " corresponding " China in above-mentioned corresponding relation
Bank ", is then merged into " Changping Bank of China " with " Changping " again, then removes inquiry POI with " Changping Bank of China ".Due to original
The different corresponding relations of acquisition after simplification some can become identical corresponding relation, so, pass through embodiment party shown in Fig. 2
Formula, can simplify and reduce the corresponding relation for needing to preserve while ensureing that user accurately searches POI, and then user passes through
Initialism is searched the corresponding relation quantity searched for during POI full name and is reduced, so that efficiency when improving user search POI.
Obtained in step 104 between initialism and POI after corresponding relation, in order to which later user searches for POI by initialism
When can using the corresponding relation need corresponding relation between the available initialism of user and POI is stored as to the corresponding relation.
In order that the corresponding relation preserved is not repeated, it can be completed after step 104 by the way of shown in Fig. 3
Store the corresponding relation obtained：
Step 301, judge whether corresponding relation is the corresponding relation stored between the initialism and POI, if it is, entering
Enter step 302, if not, into step 303；
Corresponding relation between step 302, the deletion initialism and POI；
Corresponding relation between step 303, the storage initialism and POI.
Preserving corresponding relation through the above way, there is provided be not in repetition in the corresponding relation used when being searched for user
Corresponding relation, user search for corresponding relation search correspondence POI full name when system processing time it is shorter.
In order that the corresponding relation of storage is accurate, it can complete to deposit by the way of shown in Fig. 4 after step 104
Store up the corresponding relation obtained：
Step 401, judge whether POI corresponding to the initialism is POI corresponding to the standard POI query words,
If not, into step 402, if it is, into step 403；
Corresponding relation between step 402, the deletion initialism and POI；
Corresponding relation between step 403, the storage initialism and POI.
Corresponding relation is preserved through the above way, is rejected initialism in the corresponding relation that can be storage and is looked into standard POI
Inquiry word does not imply that the corresponding relation for same place POI in itself.For example, { 42 research institutes, 428 research institutes }, initialism and mark
Quasi- POI query words refer to two different research institutes, according to above-mentioned steps, the corresponding relation be acquired after can before storing by
Reject.
In order that the corresponding relation of storage has more availability, can after step 104, by the way of shown in Fig. 5
To complete the corresponding relation that storage is obtained：
Step 501, corresponding relation between the initialism and POI is stored in correspondence set to be stored in advance；
Step 502, record time that corresponding relation between the initialism and POI occurs in correspondence set to be stored
Number；
Step 503, judge whether the number of times that corresponding relation between the initialism and POI occurs exceedes default frequency threshold
Value, if it is, into step 504；
Corresponding relation between step 504, the storage initialism and POI.
It should be noted that the corresponding relation prestored in step 501 is to be not applied to the correspondence pass used during user's search
System, the state for being corresponding relation before user's use is supplied to that prestores here.And the storage in step 504 is storage
Can store to the available corresponding relation number for being supplied to user to use specifically for the corresponding relation for being supplied to user to use
According in storehouse or tables of data.And in step 503, if the number of times that corresponding relation occurs between initialism and POI is not less than default
Frequency threshold value, the corresponding relation is not deleted typically, and is to continue with making it be pre-stored in correspondence set to be stored, with right
User's search daily record is constantly searched for and obtains more corresponding relations and be stored in advance in band storage correspondence set, the corresponding relation
The number of times of appearance may gradually increase, so as to be stored when the number of times exceedes frequency threshold value, then by the corresponding relation.
In addition, can continue to reservation record corresponding relation quilt in user's search daily record in the corresponding relation of storage
The number of times of acquisition, and then when user searches for POI, the POI of output can be according to the called number of times of corresponding corresponding relation
Order arrangement.
Store corresponding relation through the above way, then the corresponding relation for being supplied to user to be used when searching for be before user
The more corresponding relation of searching times, the frequency that user uses is larger, it is possible to increase the efficiency of systematic search corresponding relation.
The POI log contents searched for according to user are described in detail with a concrete scene below, by the present embodiment
After technical scheme processing, the corresponding relation between the initialism and POI full name of acquisition.In this scenario, corresponding relation is preserved
Frequency threshold value is 2.Table 1 is extracts from the content that the user of user journal searches for POI by initialism, and table 2 is according in table 1
