Please refer to Fig. 2, based on said method, the present embodiment is also corresponding provides a kind of system of carrying out content association according to ambient condition, comprises acquisition module 201, analysis module 202, retrieval module 203, output module 204 and judge module 205.
Acquisition module 201 is for obtaining current ambient condition.Wherein, border state comprises one or more in geographic position, temperature, humidity, sound, image, video, orientation, motion state, human body physiological parameter, place sign, object identification, user behavior feature.In specific embodiment, acquisition module 201 can also be for receiving user's input.Acquisition module 201 can be keyboard, touch-screen, microphone, camera, compass, GPS, acceleration transducer, temperature sensor etc.Acquisition module 201 comprises sensor hardware and relevant software program, also can be not comprise sensor hardware, it is software program (being commonly referred to virtual-sensor), for example, the content that user issues in social networks application program has just been expressed user's state and preference, and these information also can be used as a kind of ambient condition.Different sensors can, in different physical entities, provide the raw data of the ambient condition of collection to analysis module 202 by wired or wireless mode.
Analysis module 202, for receiving this ambient condition, is analyzed it, generates for expressing the semantic information of this ambient condition feature, and according to the semantic information generating, is configured to the key word of retrieval of content.In the present embodiment, 202 pairs of ambient conditions of analysis module are analyzed, and during generative semantics information, the expression way that analysis module 202 adopts comprises: key-value pair form, label form and word paragraph form.For example use camera to take an image that several individuals have meal around dining table as sensor, then this width image is analyzed, according to different expression waies, can export multi-form semantic information, key-value pair form may be " tone=warm tones; Content=people; Profile=irregular; Number of person=2; Object=desk; Object=cup; XX dining room, XX district, place=XX city "; Label form may be " have a meal, man, woman, has a drink "; Word paragraph form may be " two people of a man and a woman are sitting in a limit and drink cola drink, and background has large tree, lawn, hedge, XX dining room, XX district, XX city, place ".
Retrieval module 203 is for receiving this key word, and the key search of constructing according to analysis module 202 obtains content.Concrete, retrieval module 203 can be the content of retrieval coupling from the inverted index of content library.Content library comprises content and index two parts, content comprises one or more in audio frequency, video, picture, text, program code, control data, content library is according to the incidence relation of content and ambient condition, set up inverted index, the function of inverted index is: input environment state (key word), can return to the content of courses of coupling.

Content is stored in content library, and content library can be the ingredient of retrieval module 203.The content of courses of take below illustrates the organizational form of content library as example.
Conventionally, the carrier of every kind of content of courses is to have border, mutual isolation.For example: every textbook has the chapters and sections arrangement of oneself, every teaching laser disk has Content Organizing structure and the use-pattern of oneself, user can only browse a content of courses carrier inside, between different content of courses carriers, cannot provide rapidly the relevant content of courses according to same condition (ambient condition).And the Content Organizing form that adopts the present embodiment to provide, just can be so that different, oarse-grained content of courses fragmentation, abolish the barrier of various teaching content vector, can according to specific theme (ambient condition), from numerous contents of courses, extract the content being associated and present to user.
Please refer to Fig. 3, the base unit that content element is content, each content element has been expressed specific Information Communication content.
Each content element can be associated with one or more ambient condition, shows that this content element is applicable to the sight of these ambient conditions.The information that ambient condition can detect as the sensor of intelligent terminal, it may be the audio frequency that microphone receives, and may be also image or video that camera is taken, may be also the equipment moving state that detects of acceleration transducer etc.When making content, relative ambient condition sample is made in sampling; The ambient condition of content element association can increase, deletes, revise, so that content element is applicable to actual conditions more with mating of ambient condition.According to the difference of ambient condition, the method for making sample has very big difference, and same ambient condition also can be sampled in multiple dimension.For example: for this ambient condition of image, in hue dimension sampling, in the profile dimension sampling of object, in the big or small dimension sampling of object, in the sampling of material dimension etc.The current environment state ambient condition associated with content obtaining need to compare in identical dimension.
Content element 1 in Fig. 3 and ambient condition 1A, ambient condition 1B are associated; And content element 2 and ambient condition 2A, ambient condition 2B are associated.Describe environment state has two kinds of modes, a kind of is accurate description: the classification of ambient condition (according to actual needs, classification can more carefully be divided into subclass), the attribute of ambient condition and value to (Key-value), an ambient condition can comprise the right of a plurality of attributes and value; Another is fuzzy description, with one or more word tag even passage reflect the feature of environment.
Also relevant between content element, as shown in Figure 3, after content element 1 completes, can unconditionally be switched to content element 3, also can have ready conditions (having received ambient condition X) is switched to content 2.For example: content is a section audio dialogue, is talking about the thing of having a meal.If intelligent terminal is in playing the process of this section audio, user being detected and also participated in dialogue---user has said facing to microphone, think that user is to this section of content (meeting switching condition) interested, then at once or etc. play the content 2 that just can be switched to after this section audio with user's speech strong correlation; Otherwise be exactly after grade plays content element 1, then play content unit 3, be a concrete application of judge module 205 herein.
Please refer to Fig. 4, is the treatment scheme schematic diagram of acquisition module 201, analysis module 202, retrieval module 203, output module 204 and judge module 205.
1.1 obtain ambient condition: acquisition module 201 utilizes sensors sense environmental state, obtain the primal environment state of sensor output.For example: what by camera sensing device, detect is piece image, now and do not know what content image comprises; What by microphone, detect is a section audio, now and do not know what the content of audio frequency is.Certainly, some sensors may carry out initial analysis to content, the primal environment state of output has had certain semantic information, such as the longitude and latitude of GPS locating module output, be deployed in beacon unique identification that the Bluetooth beacon in environment exports etc., this class semantic information can directly be used as search key.If be equipped with multiple sensors in acquisition module 201, can collect the primal environment state of multiple sensors.
1.2 send: acquisition module 201 sends to analysis module 202 original ambient condition.
1.3 analysis environments states: 202 pairs of original ambient conditions of analysis module are analyzed, obtain the ambient condition (semantic information) of semantization, and are configured to the key word of retrieval of content.The collection piece image of take is example, and the ambient condition of semantization can be: classification=image; Key1=contour of object, Value1=is circular; Key2=color, Value2=is orange.Optionally, analysis module 202 can be accumulated the ambient condition in the past gathering, and selects the information of some or all of accumulation, sends to retrieval module 203.In specific embodiment, the priority of semantic information can be identified by certain method, for example: according to the time order and function gathering, discharge priority, according to user, the feedback of output module 204 output contents is judged the priority of semantic information etc.
1.4 send key word: analysis module 202 sends to retrieval module 203 the key word obtaining after analyzing.
1.5 retrieval of content: retrieval module 203 is compared the ambient condition sample in current ambient condition and content library according to the key word of receiving, finds the identical or close corresponding content of ambient condition sample.In the message of sending due to analysis module 202, can comprise the corresponding ambient condition of multiple sensors, so retrieval module 203 also supports to carry out from a plurality of dimensions the comparison of ambient condition.
1.6 send: the content that retrieval module 203 obtains retrieval sends to output module 204.
1.7 output contents: the content that output module 204 identifications are sent, according to the difference of content, use the output device corresponding with it to carry out output content.
1.8 obtain ambient condition: in output module 204 output contents, and the ambient condition that acquisition module 201 Real-time Obtainings are current.
1.9 send: the ambient condition that acquisition module 201 obtains by analysis module 202 sends to judge module 205 after analyzing.
2.0 judgements (switching condition): judge module 205 judges whether current ambient condition meets switching condition.
2.1 control switching: if judge module 205 determines current ambient condition, meet switching condition, produce new search key, to retrieval module 203, initiate retrieval request.
2.2 retrieval of content: retrieval module 203 obtains according to the new key search of receiving the content being associated with current content and ambient condition.
2.3 send: the content that retrieval module 203 obtains retrieval sends to output module 204.
The content of 2.4 output switchings: the content of output module 204 output switchings, it should be noted that, output module 204 can be after the output of current content the content of output switching again, also can after the switching command that gets judge module 205, switch immediately.
A kind of method and system that carrys out content association according to ambient condition providing based on the present embodiment, is described with concrete application examples below.
In concrete application examples, acquisition module 201, analysis module 202, retrieval module 203, output module 204 and judge module 205 can be in same physical entities, also may be in a plurality of physical entities.

User uses the camera of intelligent glasses to take piece image, for example: the image that on a width dining table, several individuals have meal, then this width image is analyzed.According to the difference of the analytical technology adopting, can export the semantic information of different aspects, the feature that semantic hierarchies are lower may be " tone=warm tones; Content=people; Profile=irregular "; That semantic hierarchies are higher may be " content=people; Number of person=2; Object=desk; Object=cup "; What semantic hierarchies were higher may be " two people of a man and a woman are sitting in a limit and drink cola drink, and background has large tree, lawn, hedge ".
Intelligent glasses is configured to the key word of retrieval according to current ambient condition, for example: for key-value mode using key and value all as key word; Can be directly as key word for label form; For the content of one section of word, need first to carry out word segmentation processing, then distinguish which word meaningful, select significant word to form key word.Then key word is passed to the retrieval module 506 of server, retrieval module 506 is retrieved suitable content from content library.
In content library, talk about the conversation content of having a meal and key word " desk, have a meal, drink, beverage, wine " etc. for one section and set up incidence relation, so this section audio content is matched to merit, return to intelligent glasses.
Intelligent glasses is received after audio content, just in earphone, is played back.
If in the process of playing, user has participated in dialogue with voice, intelligent glasses is analyzed the said content of user, obtain one or multinomial mixing of following content: text, the tone, emotion etc., send to server, server finds new content to send to intelligent glasses to play according to the content of receiving, has so just formed a kind of man-machine conversation based on environment sensing.
The on-line study system of this combining environmental state is particularly suitable for spoken language and the hearing of foreign language, and child, children, student's daily knowledge learning.
Application examples two: in conjunction with the assistant learning system of motion state and position
Please refer to Fig. 6, this system comprises intelligent bracelet, smart mobile phone and server.Intelligence bracelet comprises the first acquisition module 601, the first analysis module 602 and first communication module 603.Smart mobile phone comprises second communication module 604, the second acquisition module 605, the second analysis module 606 and output module 607.Server comprises third communication module 608 and retrieval module 609.
Intelligence bracelet comprises motion sensor, i.e. the first acquisition module 601, motion state that can checkout equipment holder.Through the analysis of the first analysis module 602, obtain the key word for retrieving, such as: walk, run, by bus, stair climbing etc.Intelligence bracelet by first communication module 603, is used short-range communication agreement key word, and for example Bluetooth protocol sends to smart mobile phone.Certainly, different according to the processing power of intelligent bracelet, the first analysis module 602 also can be deployed on smart mobile phone, or is deployed on server.
The second acquisition module 605 of smart mobile phone comprises: detect the microphone of audio frequency input, detect the mutual touch-screen of user and client-side program and vision content output, detect GPS or the indoor positioning functional part in geographic position.The output module 607 of smart mobile phone comprises: the display of the earphone of output audio, output multimedia page.The second analysis module 606 of smart mobile phone has been safeguarded the mapping relations of geographic position and place title in advance, can process original positional information, supplement semantic information, so just can be according to the particular location at longitude and latitude judgment device place, as " XX market ", so " XX market " can be passed to server as search key.
Comprehensive movable information and the positional information obtaining of client-side program in smart mobile phone, sends to server by second communication module 604 and third communication module 608, and for example key word is " running in XX market ".
After server is received key word, by retrieval module 609, retrieve relevant content from content library, for example the audio frequency of one section of English dialogue, discusses the commodity about moving in XX market; Or a multimedia page, shows the relevant commodity of motion that is selling in XX market.
Server sends to smart mobile phone the audio content retrieving, and smart mobile phone is play in earphone (output module 607); And above-mentioned webpage is sent to smart mobile phone, in display (output module 607), show.User can listening to audio, and watches the content of showing in display, and carries out interactive operation, and purchase commodity for example place an order.
The all right nearly step of multiple ambient condition is comprehensive, for example: smart mobile phone utilizes microphone detection user's wheeze, if motion state is to run, and continued longer a period of time, wheeze is larger, above-mentioned ambient condition is converted to new key word, sends to server.So server is retrieved the content of coupling again, to smart mobile phone, feed back new content, play.
It should be noted that, according to actual needs, each functional module can be disposed flexibly between intelligent terminal and server.
When the function ratio of intelligent terminal is weak, intelligent terminal collects after ambient condition, can not analyze, but raw information is sent to server, by server, is analyzed; If intelligent terminal function is more intense, after can analysing in depth, again result is sent to server on intelligent terminal.
