Abstract
The invention discloses an active service acquiring method based on environment perception. The method comprises the steps that a mobile client sends a request to a server; the server sends environment data needing to learn to the mobile client; the mobile client reads the environment data and stores the environment data in a (key, value) pairwise manner, then sends the environment data and an identity identification code to the server; and the server processes the environment data sent by the mobile client. By using the active service acquiring method based on environment perception provided by the invention, the effect of providing a unified development interface for developers is achieved, the development time is saved, and the development efficiency is improved.
Description
Technical field
The present invention relates to a kind of acquisition methods of taking the initiative in offering a hand based on environment sensing.
Background technology
Nearly all equipment based on Android all has multiple built-in sensors, and as accelerometer, GPS, battery, distance-sensor, the application program based on these sensing datas is widely used.In such systems, contextual information is collected and analyzes, to provide relevant service to client.Because in the quick growth of sensor technology in client, contextual information can easily obtain from sensor.
The people such as Han propose the commending system of the sentiment analysis algorithm of user by the vectorial classification as changes in emotional.The people such as Liang investigate comprehensive social background analytical algorithm, and are integrated into a commending system, provide the age based on user, occupation, the service of place and sex.The people such as Oh propose a kind of collaborative filtering with the interest of user in group quantized and significance level.In addition, the people such as D propose a kind of based on the date, temperature, season, the contextual analysis algorithm of time.These systems are widely used in various field, as tourism, and suggestion interested and health control software etc.
Above-mentioned technology does not provide a unified framework, and the basic framework of disposing for context-aware applications program is different application; In addition, these technology concentrate on low-level sensing data, and do not relate to high-level contextual information, as activity and the behavior of user.
Summary of the invention
Technical matters to be solved by this invention is, not enough for prior art, provides a kind of acquisition methods of taking the initiative in offering a hand based on environment sensing.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of acquisition methods of taking the initiative in offering a hand based on environment sensing, the main implementation procedure of the method is: mobile client sends request to service end, service end sends to mobile client by needing the environmental data known, mobile client reads environmental data, and with < key, the form storage condition data that value > is right, then environmental data and Identity Code are sent to service end, the environmental data that service end sends according to mobile client processes.
Described environmental data comprises speed, longitude and latitude, WiFi state, bluetooth state, time.
The specific implementation flow process of the inventive method comprises the following steps:
1) initialization list list, initialization key-value pair map, initialize digital exp, for the data p of each in service end, ensure that the identity field of this data p is equal with client identity, then performs following operation:
1a) initialization list array, if the serviceId field of data p is in map, then array assignment is the data be buffered in map; Otherwise it is serviceId that map adds a key, is worth the data for array, adds data p in array;
Be 1b) zero by digital exp assignment, for a data s any in map, proceed as follows:
For any data sp of the array of s, be that exp adds distance value dis by exp assignment, wherein:
Dis=1-| (the value value that the value value – mobile client of sp is corresponding) |/(the value value that the value value+ mobile client of sp is corresponding);
Determine that the end value of exp is the length of the exp after assignment divided by the array of s, in list list, add the serviceId that structure is <identity, s, the data of the end value > of exp;
2) with the addition of above-mentioned the serviceId that structure is <identity, s, the list list of the data of the end value > of exp sends to mobile client;
3) mobile client proceeds as follows according to each the data s in list list:
3a) initialization list l, obtain the mounted service list of mobile client, if data s does not exist in this service list, then added to by data s in list l, the exp descending according to data s data sorts to list l;
3b) the front n% bar data of download list l service and install these service; Rear (1-n) % bar data of list l are shown as " manual installation " icon, and when the user clicks on this icon, system downloads also installs this service;
3c) when user clicks any one service, mobile client by current environmental data with < key, the form that value > is right stores, and by this environmental data, the service respective identification that Identity Code and user click sends to service end, when service end receives environmental data, carry out following process: any < key that mobile client is sent, > is to environmental data for value, if this key is in service end and the identifier sent of identity and mobile client is identical, the value of this environmental data and the distance value dis of database intermediate value are greater than value m simultaneously, data then more in new database, weights are added 1, otherwise add a new data in a database.
The span of n is 1 ~ 99; The span of m is 0 ~ 1.
Compared with prior art, the beneficial effect that the present invention has is: present invention employs the acquisition methods of taking the initiative in offering a hand based on environment sensing, reaches as developer provides the effect of unitized overall development interface, saves the development time, improve development efficiency.The inventive method developed as framework, skeleton code only needs to write once; Using skeleton code as development library, the acquisition of concrete environmental data is defined by developer oneself, writes complete code compared to developer, uses this method to develop the exploitation amount that can reduce nearly 70% as framework.
Embodiment
Using AndroidStudio as compiler, using Android device as client terminal, exploitation client functionality, comprises request environmental parameter, collect environmental data, send environmental data, receive service list, the service of reception pushes, manual download service, sends feedback data to service end; Using PHP as service end development language, using MySQL as service end database, exploitation service end function, comprises propelling movement environmental parameter, process user environment data, produces service list and sends to client, process user feedback data more new data.
Specific experiment mode: client obtains 20 services, and user clicks first in service list, and accuracy adds 20, and user clicks second in service list, and accuracy adds 19, by that analogy; Many experiments is carried out to multiple user, calculates average accuracy and divided by service sum, show that the Average Accuracy of service is 72%.Meanwhile, recording user rests on the time of system as period of reservation of number, carries out many experiments to multiple user, show that the average user stand-by period is 8 seconds.User is investigated, show that user's average satisfaction is 75%.
