It is fully disclosed to those skilled in the art.
Fig. 1 shows the flow diagram of the method according to an embodiment of the invention for excavating map point of interest POI, ginseng
See Fig. 1, the method for the excavation map point of interest POI of the present embodiment includes the following steps:
Step S101 obtains the map vertical search log generated in preset time period, composition the first search log set；
Here preset time period, such as monthly.That is, monthly obtaining the map generated in one month in this step for the period
Vertical search log, by these map vertical search logs composition the first search log set.Based on the first search log set
To obtain new POI.Thus with POI data and data offer period is provided mainly by map vendors in the prior art with season
Compared for unit, the daily record data that can be generated in use according to the map in time, effectively excavate new POI, realize and be based on
User feedback (i.e. the map search log of user) expands the effect that high quality P OI is newly order in time, has expanded POI and has newly order excavation
New route.
Step S102 is filtered processing to the first search log set, obtains the second search log set；
Step S103 is carried out improving processing, be obtained to the query word in each search log in the second search log set
New POI.
As shown in Figure 1 it is found that the method for the excavation map point of interest of the present embodiment, is generated by obtaining in preset time period
Map vertical search log, be filtered processing, based on obtained after filtering second search log set to search log in
Query word carry out improve processing obtain new POI.So as to user's usage log data based on magnanimity, actively, in time
Excavate new POI, improve the excavation speed of POI, and filter out low-quality log by filtration treatment and also guarantee
The accuracy of the new POI excavated.
In one embodiment of the invention, processing is filtered to the first search log set in abovementioned steps S102,
Obtaining the second search log set includes: to judge in the search log every search log in the first search log set
Query word whether have map demand, if there is the search log is then put into the second search log set by map demand, such as
Fruit does not have map demand then to filter out the search log.
Here there is map demand to refer to that the search inquiry demand of user is directed to searching map, rather than be directed toward map it
Outside.In view of the function very abundant of existing map products, it can satisfy a variety of search inquiry demands of user, for example, right
The query demand of express delivery, to the query demand of route, to the query demand etc. of congestion.These query demands are for excavating
For POI is newly order, interference data are considered, therefore, by this filter condition of map demand in the present embodiment, by that
A little search query logs without map demand filter out, to reduce data processing amount, and ensure that the new point of the POI of excavation
Quality.
And judging whether the query word in a search log has a specific embodiment of map demand is to pass through tune
Interface is given a mark with preset map demand to obtain the score of the query word in the search log；According to looking into the search log
The score for asking word determines whether map demand.
That is, judging the inquiry in current search log by a marking mechanism in one embodiment of the invention
Whether word has map demand.For example, if the current search log for calling preset map demand marking interface to obtain
In query word be scored at " score:288 ", i.e., map demand marking interface returns to effective score, illustrates current search log
There is map demand.If map demand is given a mark, interface returns to " without effective score ", illustrates that current search log does not have map demand,
These search logs will can be filtered without entering in subsequent process.
In one embodiment of the invention, processing is filtered to the first search log set in abovementioned steps S102,
Obtaining the second search log set includes: that default one or more query words exclude type, in the first search log set
Every search log, judges whether the query word in the search log belongs to query word and exclude type, filters out if belonging to
The search log is put into the second search log set by the search log if being not belonging to.
Here query word excludes type and refers to the uninterested query word type in excavating the new point process of POI, for example,
Public bus network type (such as 402 tunnels), subway line type (such as No. 10 subway/light rail line) and route type (such as place A to the place B).This
A little query words are usually also not POI to be excavated and newly order corresponding query word, so, the default one or more inquiries of the present embodiment
Word excludes type, then looks into the query word for every search log that first searches in log set and preset one or more
It askes word exclusion type to be compared one by one, judges whether the query word for searching for log belongs to query word and exclude type, if belonged to
Query word excludes type and just this search log is filtered out, if being not belonging to query word excludes type, the search day
Will is put into the second search log set.Search log in second search log set is that reliability and accuracy are relatively high
Those search logs, may be used to generate new POI.
In one embodiment of the invention, if to excavate new POI point, it is necessary to the query word in log will be searched for
The identical search log of corresponding with POI already existing on line query word filters out, thus leave behind those on line
The corresponding query word of existing POI is different, may excavate the search log of new POI.Thus, it is right in abovementioned steps S102
First search log set is filtered processing, obtains the second search log set further include: in the first search log set
Every search log, judge whether the query word in the search log is the known corresponding query word of POI, is if it is filtered
Fall the search log, if not then the search log is put into the second search log set.
And judge the query word in the search log whether be the known corresponding query word of POI a specific embodiment
It is the query word in the search log to be input to POI data search engine, according to returning the result for POI data search engine
Judge whether the query word in the search log is the corresponding query word of known POI；Wherein, POI data search engine is basis
Known POI data is built on line.
That is, the data retrieval engine built using one according to POI data known on line in the present embodiment, will work as
Query word in preceding search log is input in POI data search engine, can be returned the result after the retrieval of POI data search engine,
If receive POI data search engine return query word corresponding with known POI it is identical as a result, if by this search for log
It filters.Otherwise, retain search log.The corresponding query word of upper already existing POI that goes offline, the search left can be filtered in this way
It is exactly the corresponding query word of new POI that query word in log, which has very maximum probability,.
After filtration treatment above, available second searches for log set, can direct root in one embodiment
New POI is generated according to the query word in the search log in the second search log set.But, it is contemplated that the second search log collection
Search log quantity in conjunction is still larger, in order to further decrease data processing amount, and improves the quality of new POI, this hair
In bright one embodiment after obtaining the second search log set, and to each search log in the second search log set
In query word carry out improve processing the step of before, further comprise: to second search log set in each search log
Query word carry out priority ranking；Then the query word in each search log in the second search log set has carried out
Conducting oneself well reason includes: to carry out improving processing to it according to the priority ranking sequence of each query word.
That is, then being pressed by carrying out priority ranking to the query word of each search log in the second search log set
It is carried out to improve processing according to the priority ranking sequence of each query word.For example, a search in the second search log set
The priority of query word (Qihoo 360) in log is level-one, and the query word in another search log is (near Qihoo 360
Cuisines) priority be second level, then, it is subsequent when improving POI and newly orderring corresponding query word, first improve looking into for high priority
Ask word, i.e. this query word of Qihoo 360 improves cuisines this query word near Qihoo 360 after this.So, it is possible will
The POI of more high quality newly orders corresponding query word and improves out as early as possible, and the new point of POI excavated, improves the new point of POI
Excavation speed and efficiency.
It is provided in one embodiment of the invention and the query word of each search log in the second search log set is carried out
The embodiment of priority ranking, specifically, extracting byte number respectively from each search log in the second search log set
The value of field；Byte number field indicates the byte number that server returns when user's search；If the value of byte digital section is less than
One byte number threshold value then distributes high priority for the query word in corresponding search log；If the value of byte digital section is greater than
Second byte number threshold value then distributes low priority for the query word in corresponding search log；Second byte number threshold value is greater than the
One byte number threshold value.
It should be noted that second searches for comprising a byte digital section in each search log in log set, it should
Field record user using query word when being searched on map, byte number that server returns.For example, user uses query word
For cuisines near Qihoo 360 when searching on map, the byte number that server returns is 30 (that is, the value of byte digital section is
30) it is greater than preset second byte number threshold value 12, then can be the query word in corresponding search log (that is, Qihoo 360 is attached
Close cuisines) distribution low priority.And if user using query word Qihoo 360 when being searched on map, server return
Byte number be 8 (that is, the value of byte digital section is 8) less than the first byte number threshold value 10, then in corresponding search log
Query word (that is, Qihoo 360) distributes high priority.
Why by server return byte number size come for query word distribute different priority be because, when
The query word of user more levels off to a POI when newly orderring, the corresponding very little of POI number of results that server is found, that is, meets inquiry
The fruiting quantities of condition are few, this also illustrates that query word is likely to be an accurately POI.And if the query word of user is more inclined
Point new from POI, for example, only one return inquiry, then the POI number of results that finds of server accordingly will be very big, that is, meet
The fruiting quantities of querying condition are more.Based on this, the query word of each search log in the second search log set can be carried out
Priority ranking.To which more in time, accurately excavating out POI newly orders corresponding query word.
From the foregoing, it will be observed that the method for the present embodiment based on map vertical search log, utilizes query word analysis and data
The means such as search engine filtering, efficiently excavating from (for example, monthly) massive logs generated in predetermined period may be at
The query word newly order for POI.
The step of method for excavating map point of interest POI, is illustrated below with reference to a specific example.
Step S201 obtains daily record data.
In the present embodiment, using the moon as the period, map vertical search log on line, the map vertical search log recording are obtained
There are the information such as query word and the city of user.
Step S202 filters out the query word of map demand.
A log is inputted when per treatment, and whether the query word in current search log is judged by a marking mechanism
There is map demand.
For example, current query word to be processed is " China Township Enterprises Association ", preset map demand marking is called to connect
MouthfulHttp:// xx.qihoo.net/get_score? q=China Township Enterprises AssociationObtain the demand score of the query word
score.Map demand is judged whether there is according to the score of the query word in the search log.For example, obtain the result is that
" score:288 ", that is, return to effective score, then illustrates that the query word in the search log has map demand.On the contrary, if inquiry
Word is " express delivery inquiry ", returns to " without effective score " after calling preset map demand marking interface, illustrates no map demand, this
Query word in a little search logs would not enter in subsequent process.
Step S203 filters the query word for type of loseing interest in.
Default one or more query word excludes type (that is, uninterested query word type), is analyzed using query word
Technology is come in analytical procedure S202 to filter out the query word of uninterested type by the data of marking, such as " public transport ",
" route " etc..
Such as: the group of current query word and urban information to be processed is combined into " 402 tunnel Changsha ", judges in the search log
Query word whether belong to query word exclude type, the search log is filtered out if belonging to.Specifically, being adjusted in the present embodiment
With interface "Http:// xx.qihoo.net/qp? q=402The Changsha Lu &c=", if interface returns to " bustype (bus)
Type:orig | 402 road public bus networks " queryinfo ": " route_info ": " tag ": " ", " type ": 46, "
trigger_type":0}}}".Then explanation is the query word of " public bus network " type, belongs to uninterested inquiry part of speech
Type then filters out the search log where the query word, i.e., this kind of query word will not enter in follow-up process.
Step S204 filters the corresponding query word of already existing POI on line.
Processing in this step is that the query word Jing Guo above step is input in POI data search engine, the POI
Data retrieval engine is the data retrieval engine built using data on line, can filter the upper already existing POI that goes offline
Corresponding query word.It is the corresponding query word of POI that the query word left, which is considered having very maximum probability,.
For example, calling following interfaces, query word is input in POI data search engine.
Http:// xx.qihoo.net/search.htm? count=10&nouniq=1¶m=sep_fuzzy: 0|word_rank_rate:1|sep_title:0|sep_dint:0|sep_synm:1|sep_uniq:parentid&filter =0&start=0&kw=content | (Qihoo 360) city | (Beijing) &ics=utf-8,
The corresponding POI of the query word whether is had existed on the interpretation of result line returned according to POI data search engine, if
In the presence of then this query word is filtered out.
Step S205 generates doubtful new POI according to corresponding query word.
By several steps before, obtained query word is tentatively available, but searches for the quantity of log and query word
It is still larger.It to improve service efficiency, is further processed in this step, that is, in search log in the second search log set
Query word distribute priority, preferentially improve the query word of high priority.
It should be noted that clothes when having byte number field identification user search in original map vertical search log
The byte number that business device returns, this field information can be used to distribute priority for query word.Fig. 2 shows according to the present invention one
The map search result schematic diagram of a embodiment, Fig. 3 show another map search result according to an embodiment of the invention
Schematic diagram.Referring to fig. 2, when user is searched on map using query word " Qihoo 360 ", the byte number that server returns is opposite
It is less, only include the related data of a POI point (Beijing Qihu Technology Co., Ltd.), illustrates that server precisely returns some
POI。
Referring to Fig. 3, when user is searched on map using query word " cuisines near Qihoo 360 ", server is returned
Byte number it is relatively more, containing three POI points, (one is 360 dining rooms, and one is cheerful dining room, there are one being Zhao Sheng
Remember steamed dumping shop winebibber's bridge shop) related data.This just illustrates that this query word is a general inquiry, is not to some specific POI
Retrieval, corresponding query word priority can be toward heel row.In this way, by setting byte number threshold value, and server is returned the result
Byte number and byte number threshold value comparison be that can determine the priority of query word.
Step S206 improves inquiry word information, obtains new POI.
In this step, the query word in each search log in the second search log set filtered out is carried out perfect
Processing, obtains new POI.Specific perfect processing is such as to be grabbed from internet page by some crawler means and inquiry
The relevant information of word, such as address information, to improve the information of query word, to obtain new POI.
It is subsequent, it can realize and expand by the higher new POI mark of the quality excavated by above-mentioned steps on the electronic map
Charge sub- map products POI coverage rate, improves the purpose of electronic map competitiveness.
