In step sl, the searching request of user is obtained.
Particularly, the searching request of user is obtained by such as keyboard, touch-screen, speech input device etc.Such as obtain the searching request that user is initiated by the search terms in webpage clicking etc., such as obtain the searching request that the search terms " quite cheap special price " in the direct webpage clicking of user is initiated, or obtain user by embedding the searching request of local search hurdle initiation in a browser, such as obtain the searching request that user initiates in Baidu's search column inputted search word " automobile ".Certainly, any other mode that can obtain user search request is all applicable to the present invention, is contained in this by reference at this.
In step s 2, obtain the scene information that user is current, judge current scene type according to current scene information.
Its Scene refers to the conditions and environment residing for user, such as the geographic position at user place, the network condition etc. of periphery.Scene information herein includes but not limited at least one item in user's current context information, terminal hardware information, terminal applies information and the network information.Alternatively, user's current context information comprise the current movement velocity of the current geographic position of user, user, towards direction, background sound, one or more in illumination; Terminal hardware information comprises at least one item in terminal models (such as the mobile phone of millet 2S), terminal cpu type; Terminal applies information comprises at least one item in terminal residual electricity, terminal operator (movement, UNICOM, telecommunications); The network information comprises at least one item in terminal network type (such as 2G, 3G, 4G or wifi), surrounding network.Certainly, above-mentioned scene information is only example, is not limited to this, and other scene informations are included in wherein equally, the information that the various application programs that in such as terminal, user installs provide, and such as map class applies the current traffic information etc. provided.At this, scene type is judged or/and limit by any one or more combination included but not limited in scene information.Wherein, described terminal includes but not limited to that computing machine, mobile terminal, panel computer etc. can carry out mutual electronic equipment with user.
Some scene informations that wherein user is current can obtain in the following manner:
-for the geographic position at user place, gathered by the alignment sensor of user terminal;
-for the current illumination of user, gathered by the light sensing sensor of user terminal;
-the user terminal itself of automatic detection function provided by to(for) terminal models, terminal cpu type, terminal network type, surrounding network, terminal operator, terminal residual electricity etc. is obtained.
Certainly, the mode of above-mentioned acquisition is only citing, and the scene information that terminal is directly obtained or indirectly obtained by third party or obtains also is contained in this.Certainly, different information to be gathered separately by corresponding sensor or the combination of multiple sensor gathers, at this, the type of sensor is not construed as limiting.
Further, current according to user scene information judges current scene type.Also namely, according to the geographic position at such as user place included in current scene information, the network condition etc. of periphery.Scene information herein comprise the current movement velocity of the current geographic position of such as user, terminal models (such as the mobile phone of millet 2S), terminal cpu type, terminal network type (such as 2G, 3G, 4G or wifi), surrounding network, terminal operator (movement, UNICOM, telecommunications), terminal residual electricity, user, towards direction, background sound, one or more combination in illumination to be to judge the scene type that user is current.Such as, the scene type that user is current is judged according to geographic position, background sound, typically, judge that the current scene type of user is as " No. 19, Zhongguancun Street+new Zhong Guan shopping center " according to the current geographic position " No. 19, Zhongguancun Street " of user, background sound " noisy ".
For some typical information in current scene information, judge current scene type in the following manner:
-level of consumption and the consumption habit of user is judged according to the terminal models of user.Usually, the terminal of different model has different prices, and user selects the terminal of different model also to represent the level of consumption and the consumption habit of user to a certain extent.Typically, obtain using the user of A model-millet mobile phone in consumption, usually focus on the cost performance of commodity by statistics, pay close attention to the parameter of commodity, and use the user of Type B number-i Phone in consumption, usually relatively more pay close attention to the popularity degree of commodity, further, select the user of A model-millet mobile phone usually lower relative to using the customer consumption level of Type B number-i Phone.At this, the user of the terminal using the different price of different model can be carried out classify and grading based on the level of consumption and consumption habit, and based on classify and grading, search is optimized.Such as, according to the difference of terminal price, by price at the users classification of " more than 5K " to the level of consumption " A level "; By price at the users classification of " 3K-5K " to the level of consumption " B level "; By price at the users classification of " 1K-3K " to the level of consumption " C level ", by price at the users classification of " below 1K " to the level of consumption " D level ", correspondingly, in search step, for identical search requests, provide based on different classify and gradings the Search Results that cost performance is different with price respectively.At this, the method for classify and grading can be realized by relevant sorter, and by continuing to optimize classify and grading effect to the training of sorter.
-the acceleration that gathers according to the acceleration transducer of user terminal and gyro sensor and angular speed judge the movement velocity that user is current, and based on movement velocity judge user mode of advancing (as by bus or walking); Wherein, acceleration transducer is for measuring the acceleration of carrier (as user terminal) on three change in coordinate axis direction, and gyro sensor is for measuring the angular speed of carrier (as user terminal) on three change in coordinate axis direction.Certainly, also have other for gathering the device of carrier acceleration and angular speed as applicable the present embodiment, be also contained in this.Alternatively, can also in conjunction with other sensors such as measuring three axle geomagnetic sensors of dimensionally magnetic intensity, to revise further the acceleration of acceleration transducer and gyro sensor collection and angular speed, the acceleration measured by raising and the accuracy rate of angular speed.
-the angular speed that gathers according to the gyro sensor of user terminal judge user towards direction, the concrete mode judged is in this no limit.
Alternatively, according to the current geographic position of user, current movement velocity and current towards direction, judge that user is about to the destination arrived, such as according to the current geographic position " south gate, Olympic Forest Park " of user, current movement velocity " 40 kilometers/hour ", current towards direction " south orientation ", judge that the destination that user is about to reach comprises Bird's Nest, National Convention Center etc.
Alternatively, according to the illumination obtained, judge that user is in indoor or outdoor.
Alternatively, according to the background sound obtained, judge that user is positioned at office space, family or market etc.
At this, content included by scene type described above is only in order to example, do not limit at this, both can comprise and directly judge based on the data gathered the content that obtains, the movement velocity that the user such as judged based on the acceleration transducer of user terminal and the acceleration of gyro sensor collection and angular speed is current, also can comprise and indirectly judge based on the data gathered the content that obtains, such as judge based on the acceleration transducer of user terminal and the acceleration of gyro sensor collection and angular speed the movement velocity that user is current so judge the current mode of advancing of user (as by bus or walking).
In step s3, based on searching request and current scene type, obtain the Search Results matched.
As described above, for identical searching request, user's search need under different scenes is normally different.Typically, the current scene information of obtained user " geographic position: A electronic mall is passed through; Movement velocity: 3 kilometers/hour; Mobile phone model: i Phone 5 " judge that the current scene type of user is for " A electronic mall+shopping+level of consumption A level "; when user initiates searching request based on search word " apple ", the Search Results such as brand shop, maintenance center relevant to electronic product " apple " in A electronic mall is supplied to user; And for example, the current scene information of obtained user " geographic position: B fruit wholesale market is passed through; Movement velocity: 2.5 kilometers/hour; Mobile phone model: red rice mobile phone " judge that the current scene type of user is for " B fruit wholesale market+shopping+level of consumption D level "; then when this user initiates searching request based on same search word " apple ", the Search Results such as trade company, position relevant to fruit " apple " in B fruit wholesale market is supplied to this user.
-alternatively, judge that user's current scene type is indoor or outdoor according to illumination, based on same searching request, obtain the different Search Results matched.Such as, for the searching request that same search word " drcssing index " is initiated, the Search Results provided for the user being positioned at indoor is different from for being positioned at outdoor user.
-alternatively, according to the difference of user terminal model, based on same searching request, obtain the different Search Results matched.Such as, for the searching request that same search word " automobile " is initiated, for the user using high price mobile phone, there is provided to it and be partial to the relevant Search Results of price is relatively high, style is relatively new automobile, for the user using low price mobile phone, provide to it and be partial to the relevant Search Results of price is relatively low, discount is relatively high, practicality is stronger automobile.
-alternatively, according to the difference of operator included in obtained scene information, based on same searching request, obtain the different Search Results matched.Such as, for the searching request that same search word " telephone expenses are preferential " is initiated, the Search Results provided for " movement " terminal user is different from for " UNICOM " terminal user.
-alternatively, according to user terminal network type (such as 2G, 3G, 4G or wifi) or/and the difference of terminal residual electricity, based on same searching request, obtain the different Search Results matched.Such as, for the searching request that same search word " news " is initiated, for the user using 2G network, low electricity, provide the text class relevant to news or/and the Search Results of picture category to it; For the user using 3G, 4G or wifi network, sufficient electricity, provide the Search Results that comprise text class, picture category, audio frequency and video class relevant to news to it.
