Fig. 2 is the method flow diagram of the casting material provided in an embodiment of the present invention for excavating induction point, as shown in Fig. 2, should
Method may comprise steps of:
In 201, identify that route describes the content of text of class from network media information.
Network media information is obtained first.Network media information can include but is not limited in this application: such as user
In blog, microblogging, wechat, video website etc. from the information of media releasing, in traditional networks matchmakers such as news category website/applications
The information issued on body, the information etc. of reporting of user in map class application.
The network media information issued recently, warp can be obtained by the open interface of the above-mentioned network media in this application
After crossing a series of strobe utilities such as anti-cheating, the acquisition work of network media information is completed.
Network media information in view of acquisition may be magnanimity, need therefrom to extract the content of casting value, and
Just there is the text for often describing class for route casting to be worth, and such as " Tianfu Avenue street lamp, which does not work, leads to occur serious thing
Therefore ", " Jinan Mountain Areas of Southern section A uneven, it is ruined can't bear, occur overturn accident " etc. about driving experience, accident etc. believe
Breath.Therefore in this step, it can use the disaggregated model pre-established, identify route from the network information that user issues
The content of text of class is described.
Wherein disaggregated model describes class text according to the route marked in advance and non-route describes class text and is trained
It arrives.Specifically, it can collect in advance and mark route and describe class text as positive sample, the non-route of random collecting describes class text
As negative sample, train classification models.After the disaggregated model is by carrying out word segmentation processing to positive sample and negative sample, word is established
With the probabilistic relation of classification.It can export whether the text belongs to route description after inputting a text by disaggregated model
Class text.Wherein disaggregated model can use Naive Bayes Classification Model, support vector cassification model, k nearest neighbor classification mould
Type etc..
In 202, using the road dictionary pre-established, text relevant to road is obtained from the content of text identified
This content.
And the content of text that not all route describes class all has navigation casting value, some routes describe class text not
Can be related to specific road, such as " this road is rugged be really too difficult walk ", it is led then this text does not have yet
Boat casting value.Therefore in this step, it can use the road dictionary pre-established, obtained from the content of text identified
Content of text relevant to road.
It may include the title of road in road dictionary, the route that can be will acquire describes class text and road dictionary carries out
Matching, if hitting road name therein, then it is assumed that be content of text relevant to road.May include in road dictionary
A variety of titles such as official name, alias, the historical name on road, to be suitable for different road calls.
In 203, content of text relevant for road carries out abstract extraction and is matched to induction point, obtains being matched to
Induction point casting material.
Abstract extraction is carried out firstly, for the relevant content of text of road.In this application can using at present relatively at
Ripe abstract extraction technology extracts the key content and compressed text amount of text.Therefore, the application for abstract extraction mode simultaneously
It is without restriction.
Then, the clip Text relevant to road of extraction is matched to the induction point on the road, obtains being matched to
Induce the casting material of point.Wherein it is possible to which clip Text to be matched to the induction point of link entry.It preferably, can foundation
The content of text in clip Text institute source determines the matched induction point of clip Text institute, that is to say, that according to clip Text
Context matched induction point to determine.The preferred embodiment is specifically described below:
If the content of text in clip Text institute source only includes road information, the clip Text of extraction is matched to the road
The induction point of road entrance.For example, from " each night walks alone Central Shanxi Plain loop wire, all as never knowing that the end at which, without road
Lamp is the more high beams of cart entirely, and what is felt is panic dearly entirely " text in extract abstract " Central Shanxi Plain loop wire night do not have
Street lamp, and cart is more ", then by the induction point of the entrance of the digests match to Central Shanxi Plain loop wire.
If the content of text in clip Text institute source includes the POI (Point Of Interest) on road and the road,
The induction the point then clip Text of extraction being matched near the POI.For example, from " the neighbouring street lamp of Chengdu Tianfu Avenue KFC
It does not work, and there is no deceleration strip, a white Rolls-Royce knocks two passerbys down, and two people are dead on the spot dut to serious wound "
Text in extract abstract " Tianfu Avenue street lamp does not work, without deceleration strip ", POI KFC involved in Yin Wenben, therefore can be with
By in the digests match to Tianfu Avenue at 50 meters of KFC of induction point.
If the corresponding clip Text of an induction point is obtained through the above way, using the clip Text as the induction
The casting material of point.If obtaining the corresponding more than one clip Text of an induction point through the above way, one is therefrom selected
Casting material of the clip Text as the induction point, or selected section or all progress from the more than one clip Text
Casting material after merging as the induction point.Casting material database is added in the casting material of each induction point again.If passing through Fig. 2 institute
The mode for showing embodiment obtains the corresponding casting material of induction point, and material is respectively broadcasted in broadcasting material database can be with
Induction point is used as major key or index.In addition, such as lanes side obtained in the prior art by traditional road acquisition mode
Casting material can also be added jointly to, the lane casting material that each induction such as regulation, camera, traffic sign is put of restricting driving
Library.Equally, if leading to the corresponding multiple casting materials of an induction point after being put in storage jointly with the casting material that the prior art obtains,
A casting material can be therefrom selected, or multiple casting materials are merged into a casting material.
It gives one example below for the column of process shown in Fig. 2:
The content of text for identifying that following route describes class in content is reported from blog, microblogging etc. from media, and using in advance
The road dictionary first established therefrom obtains content of text relevant to road.Assuming that getting text relevant to " Central Shanxi Plain loop wire "
Content is as follows:
" 107 provincial highways (Central Shanxi Plain loop wire) Weinan city Linwei district shows that the town the Lintong District intersection Xiang Qiao village Tian Shi does not have road at night
Lamp, no deceleration strip, both sides of the road are all villages ".
" nearly 500 kilometers of Central Shanxi Plain loop wire overall length, without street lamp, part way is dusty, it is all patching up forever, vehicle
Flow is big, and 70% is small enough to big lorry ".
" each night walks alone Central Shanxi Plain loop wire, is that cart is more entirely without street lamp all as never knowing that the end at which
High beam, what is felt is panic dearly entirely ".
After carrying out abstract extraction to above-mentioned content of text, made a summary " Central Shanxi Plain loop wire night does not have a street lamp, and cart compared with
It is more ", it can be using the abstract as the casting material of the induction of the entrance of Central Shanxi Plain loop wire point.By this from network media information
Obtain induction point casting material a mode, compare be based purely in the prior art road network information acquisition mode obviously make in
It is more abundant and comprehensive to hold dimension.
Fig. 3 is the method flow diagram of the casting content template provided in an embodiment of the present invention for excavating navigation spots, such as Fig. 3 institute
Show, this method may comprise steps of:
In 301, the historical track behavior of each user is analyzed, abnormal track is obtained.
Wherein, abnormal track can include but is not limited to: track of driving against traffic regulations yaws driving trace, is obvious unreasonable
Driving trace etc..
It in this step can be by the historical track behavior of each user and road information, traffic lights information, traffic rules etc.
It is matched, finds track of driving against traffic regulations.Such as the driving trace of hypervelocity, the driving trace illegally turned to, the traveling made a dash across the red light
Track, retrograde driving trace, the driving trace illegally moved backward, illegal lane change etc..The historical navigation of user can be travelled into rail
Mark is compared with historical navigation track, finds yaw driving trace.Can also be regular by preset bad example (Bad Case),
All following high speeds upper same high speed again is found, the obvious unreasonable row such as crossing straight trip is returned to after crossing is turned right
Sail track.
In addition to it is above-mentioned matched or compared to obtain the mode of abnormal track automatically other than, can also combine or using artificial
The mode analyzed historical navigation driving trace obtains abnormal track.
Above-mentioned exception track can be as unit of section, can also be as unit of two neighboring induction point.For example, false
If in the historical navigation driving trace of certain user, act of violating regulations occurs at the L of section, it is determined that section L is abnormal track.Example again
Such as, it is assumed that in the historical navigation driving trace of certain user, yawed at section M and N, it is determined that section M and N are abnormal rail
Mark.For another example assuming in the historical navigation driving trace of certain user, occur between induction point m in the X of section and induction point n non-
Method lane change, it is determined that inducing point m in the X of section and inducing the track between point n is abnormal track.
That is, the abnormal track obtained in this step can be one or more section, it is also possible to Yi Tiaolu
Part range in section.
In 302, the casting material of the preamble induction point of abnormal track is combined, obtains each induction point information collection
It closes, and records the corresponding abnormal track scene of each induction point information aggregate.
The casting material of the preamble induction point of an abnormal track is combined in this step, is obtained more than one
Induction point information aggregate.Wherein the preamble induction point of the abnormal track of this set before can be abnormal track duration, set away from
From or setting number induction point.When being combined, can be combined according to user by the sequence of each induction point, each group
The induction point for including in conjunction is continuous.
Wherein the casting material of each induction point can be obtained from casting material database, and casting material database can use above-mentioned figure
Mode shown in 2 embodiments is excavated to obtain.
For example, user have passed through 3 inductions within 500 meters of distance before the abnormal track driven in the wrong direction on a major trunk roads
Point is respectively by the sequence that user passes through: induction point a, induction point b and induction point c, the casting material of each induction point are as follows:
Induce point a: casting material a1 broadcasts material a2；
Induce point b: casting material b1,
Induce point c: casting material c1 broadcasts material c2.
It obtains inducing point information aggregate as follows after being combined in the manner described above:
Set 1: casting material a1 broadcasts material b1, broadcasts material c1；
Set 2: casting material a1 broadcasts material b1, broadcasts material c2；
Set 3: casting material a2 broadcasts material b1, broadcasts material c1；
Set 4: casting material a2 broadcasts material b1, broadcasts material c2；
Set 5: casting material a1 broadcasts material b1；
Set 6: casting material a2 broadcasts material b1；
Set 7: casting material b1 broadcasts material c1；
Set 8: casting material b1 broadcasts material c2；
Set 9: casting material a1；
Set 10: casting material a2；
Set 11: casting material b1；
Set 12: casting material c1；
Set 13: casting material c2.
The corresponding abnormal track scene of the available above-mentioned set of road network information according to abnormal track and abnormal track.
Assuming that the corresponding abnormal track scene of above-mentioned 13 set are as follows: tunnel exit with a distance from crossroad less than 100 meters, category of roads
Reach national highway grade, GPS signal is poor in tunnel.
It is in 303, the induction point information aggregate of the same abnormal track scene of correspondence is for statistical analysis, extract each induction
The casting content template of point.
The induction point information aggregate of the same abnormal track scene of all correspondences is for statistical analysis, it is full to obtain frequency of occurrence
The induction point information aggregate of sufficient preset requirement, such as the induction point information aggregate that frequency of occurrence is most.Utilize the induction point information
Gather included casting material building casting content template, point information collection can be induced using the casting content template as corresponding
The casting content template of first induction point in conjunction.
It may include variable element and preset parameter in the casting content template finally constructed, can also only join comprising variable
Number.Wherein variable element includes more than one induction point identification, to (in step 103 shown in Fig. 1) in the future for induction point
When generating navigation casting content, determine according to induction point identification from the casting material of corresponding induction point broadcast in content template can
Variable element.
Wherein preset parameter can be by manually adding, can also be with molar in the use casting that mode generates in the prior art
Plate combines.
It can be by the casting content template generated according to process shown in Fig. 3 and using the casting that mode generates in the prior art
It is common to be added in casting template library after content template establishes priority relationship.That is, an induction in casting template library
Point can correspond to more than one casting content template.Casting template library in respectively broadcast content template can using induction point as
Major key or index.
With continued reference to Fig. 1.
In 103, using the casting material and casting content template of induction point, content is broadcasted in the navigation for generating induction point.
Wherein, casting content template includes variable element, also may include variable element and preset parameter.According in casting
The mark for the induction point that variable element includes in molar plate determines molar in the casting of induction point using the casting material of induction point
Content is broadcasted in variable element in plate, the navigation for generating induction point.
