Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, Fig. 1 shows the schematic flow sheet of the adolescent psychology pressure detection method based on microblogging that one embodiment of the invention provides, and the method comprises the steps:
101, for the microblogging in younger population, each choosing in predetermined amount of time in microblogging pushes away literary composition and detects, and extracts all several features relevant to psychological pressure pushing away literary composition.
102, according to several features relevant to psychological pressure described, obtain all pressure type pushed away in literary composition, and adopt the sorter preset to obtain degree of pressure corresponding to described pressure type.
Wherein, sorter comprises: Naive Bayes Classifier, support vector machine classifier, artificial nerve network classifier, random forest sorter and Gaussian process sorter.And the pressure type pushed away in literary composition comprises: school work pressure academic, causalgia interpersonal, human communication pressure affection and autognosis pressure self-cognition.
Concrete testing process is as follows: these features in teenager's microblogging taken into account, then give the problem definition of the adolescent psychology pressure detection based on wall scroll microblogging.Make Category={NULL, academic, interpersonal, affection, self-cognition} are the set of pressure type, and wherein, NULL represents unknown pressure type.Make Level={none, very light, light, moderate, strong, very strong} is the set of degree of pressure, and wherein, none indicates without degree of pressure.Literary composition is pushed away for given microblogging, its pressure sensing result or be null (represent pressure do not detected), or be several tuple PressureDetect (tweet)=< (C1, L1),, (Cn, Ln) >, wherein Ci ∈ Category, represents the pressure type detected; Li ∈ Level (1≤i≤n), represents the degree of pressure detected.
103, according to described pressure type and degree of pressure, pressure polymerisation is carried out to all literary compositions that pushes away, and obtains comprehensive pressure fluctuation status figure.
Wherein, the operation rules such as maximal value, mean value or summation are adopted to be polymerized all degree of pressure pushing away literary composition in special time period.
Specifically, the pressure sensing result of a series of microbloggings that one or more teenager issues is polymerized, can the potential pressure trend of aid forecasting, process and push away uncared-for pressure state in the testing result of literary composition at wall scroll, make a general survey of the fluctuation situation of pressure in a period of time.The significant challenge faced during polymerization is, most of teenager gets used to when writing microblogging using nonstandard language format, and the vocabulary relevant with degree of pressure to pressure theme lacks sometimes.Therefore, in a microblogging sequence during detected pressures, need the problem processing this imperfection.
Consider that teen-age pressure can continue for some time, researcher regards the adjacent pressure type pushed away in literary composition as the current implicit pressure type pushed away in literary composition.Same, because emotion has continuation, the adjacent pressure mood pushed away in literary composition also can have an impact to the current literary composition that pushes away.Therefore, researcher pushes away the degree of pressure in literary composition according to former, fills up current and pushes away the degree of pressure lacked in literary composition, and the stationery that pushes away more closed on has higher influence power.
Given one pushes away civilian sequence <t1, t2 ..., tn>, without loss of generality, can implement different aminated polyepichlorohydrin (as: on average, summation, statistics number, maximal value, minimum value etc.).Such as, < (C, L1) is made,, (C, Lx) > is the pressure sensing result sequence of certain teenager one week interior institute issuing microblog, its pressure type is C, then can to average computing to this sequence
104, according to described comprehensive pressure fluctuation status figure, corresponding vasodilator effect is selected to dredge.
Wherein, dredge in assembly at adolescent psychology pressure, based on the pressure type detected and pressure rank, corresponding leading method is provided, as shown in Figure 3, comprise five kinds of main method: one is the microblogging resource of recommending front positive, and form comprises word, picture, video etc.; Two is for teenager recommends the video of relaxing exercise, guides teenager to be eased off the pressure by motion; Three is for teenager sets up mood daily record originally, and this platform carries out preserving to teen-age daily record and manages, and teenager carries out the hair style of pressure mood by writing daily record; Four is chat and the encouragement of carrying out virtual friend's formula with teenager, pours out one's woes by listening attentively to teenager, and transfer teenager notice dredges teen-age psychological pressure; Five is when teenager is in enormous pressure state, is reserved in the contact method of this platform, in the mode of sending short messages, teen-age pressure state is notified guardian by guardian, pays close attention to and helps to alleviate teen-age pressure.Specifically:
(1) the microblogging resource of recommending front positive.
For different degree of pressure, we recommend different pressure leading methods for teenager.For the teenager that degree of pressure is lighter, the picture of pursuing a goal with determination property, word and a short tale etc., can make teen-age thinking be inspired, reach the effect that oneself convinces by patient analysis in reading.Therefore, for the teenager of degree of pressure comparatively light (rank 1-2), we carry out pursuing a goal with determination the recommendation of material.
To pursue a goal with determination picture: the perception of adolescent psychology pressure with dredge platform in background data base according to four kinds of pressure type (school work pressure, causalgia, human communication pressure, autognosis pressure), picture library is divided into four classes.According to the main pressure type that pressure sensing module perceives, the picture in this platform this pressure type of automated randomized selection storehouse, if user thinks that the picture of Stochastic choice needs adjustment, can also picture in manual selection pressure type and storehouse, send.Every pictures stores corresponding comment in storehouse.Send band pursue a goal with determination picture microblogging after, this platform, by teen-age mode, to be encouraged it and pressure is dredged.
To pursue a goal with determination well-known saying: the perception of adolescent psychology pressure with dredge the famous sayings of famous figures of pursuing a goal with determination that platform stores automatic network in background data base, according to four kinds of pressure type (school work pressure, causalgia, human communication pressure, autognosis pressure) recommend respectively.Similar with the way of recommendation of picture of pursuing a goal with determination, according to the main pressure type that pressure sensing module perceives, well-known saying of pursuing a goal with determination in this platform this pressure type of automated randomized selection storehouse, if user thinks that the well-known saying of Stochastic choice needs adjustment, can also send by the well-known saying in manual selection pressure type and storehouse.Send band pursue a goal with determination well-known saying microblogging after, this platform, by teen-age mode, to be encouraged it and pressure is dredged.
To pursue a goal with determination a short tale: with name of pursuing a goal with determination make peace pursue a goal with determination picture unlike, the text of a short tale of pursuing a goal with determination is longer, teenager more can be attracted to drop into, compare deep thinking, guides its equanimity gradually, dredges pressure.Therefore the perception of adolescent psychology pressure with dredge the story of pursuing a goal with determination that platform stores automatic network in background data base, recommend according to four kinds of pressure Class (school work pressure, causalgia, human communication pressure, autognosis pressure) respectively.After the link having pushed a short tale of pursuing a goal with determination, by teen-age mode, remind it to pay close attention to this microblogging, thus guide this teenager to dredge pressure.
(2) video of relaxing exercise is recommended.
Breathe and people can be allowed anxiety to be unloaded with loosening all muscles campaign, calm down mood.By recommending the video of relaxing exercise for teenager, teenager is guided to be eased off the pressure by motion.Psychological study shows, under nervous anxiety is not present in physical relaxation state.When human body loosens, breathe usually dark and completely, result from belly but not chest.Because abdominal respiration can provide more oxygen, more effectively discharge vivotoxin, people can feel more to loosen, notice more easily concentrates, thus produce a series of relaxation effect, and abdominal respiration and tension can not occur simultaneously.
(3) mood daily record is set up originally
For teenager's (degree of pressure derives from the result of pressure sensing module) that degree of pressure is larger, we record mood daily record by auxiliary its.By the form of word, pressure is carried out expressing and discharging, alleviate psychological pressure.Simultaneously adolescent psychology pressure perception with dredge platform and also support checking the daily record of history mood.
Daily record generates: the perception of adolescent psychology pressure with dredge platform and provide mood log recording interface for there being the teenager of pressure, encourage teenager to give vent to pressure by the mode writing daily record, thus reach the object of dredging pressure.This platform delivers the time for the automatic log of teenager, and by log content and time stored in background data base.This platform provides newly-built daily record, preserves daily record, removes the options such as daily record, provides perfect daily record issue and management function.
History log is checked: for history log, the perception of adolescent psychology pressure with dredge platform and check and management interface for teenager provides.By this interface, teenager can check oneself history log record also can carry out deletion action to history log.This platform is checked by daily record and the interface that a series of function is the maintenance log that teenager provides convenience such as to be generated, and helps it to be oneself safeguard a complete mood log.
(4) chat and the encouragement of virtual friend's formula are provided
When teenager is in pressure mood, dredge pressure for it, to teen-age positive meaning of growing up healthy and sound in the mode of intelligence chat.The main design thought of this platform acknowledgment strategy listens attentively to user to pour out one's woes, split-up user notice, makes it to fade from memory making its offending thing, ites is desirable to pass through cyberchat, reach the object of dredging adolescent psychology pressure.Platform is while reception teenager session statement, and Pressure Analysis algorithm will judge whether session statement comprises pressure mood, and source pressure is divided into this four large class of school work, interpersonal relation, emotion and autognosis and under segmentation type.Meanwhile, whether Pressure Analysis algorithm will be also that several aspect such as question sentence, confirmative question judges to session statement, and the answer for answering system provides necessary foundation.Platform answer statement has two to originate greatly: Baidu is known and local statement library, be whether question sentence for classification foundation, utilize pressure information to be auxiliary, provide a suitable reply.In cyberchat, acknowledgment strategy as shown in Figure 4.
(5) guardian/teacher/friend is notified
By the perception of adolescent psychology pressure and the pressure sensing module dredging platform, this platform can obtain a certain teen-age pressure rank and pressure type.For the teenager that pressure rank is very high, the leading methods such as pursuing a goal with determination property material and easily game, owing to being the angle of dredging for oneself, therefore can not reaching and well dredge effect.And for the very large teenager of pressure, pressure is dredged very urgent timely, thus the extreme serious consequence avoided adolescent psychology pressure excessive and produce.Based on such idea, adolescent psychology pressure is dredged modular design and is notified this module of guardian.By in time teen-age severe stress situation being notified its guardian, psychological pressure is avoided to continue effective precautionary measures of diffusion with tutorial intervening acts.
Note generates: it is the personal information (guardian's name, telephone number etc.) being reserved in this platform by guardian that this platform contacts tutorial method, sends note by third party's SMS platform to it.The generation of short message content is determined by the sensing results of pressure sensing module, comprises teen-age personal information, teen-age pressure rank, teen-age pressure type etc., to cause guardian for the concern of adolescent psychology pressure.
Short message sending: the short message sending service that this platform uses third party's short message sending service provider to provide sends note for guardian, according to the short message content automatically generated above, sends note, and file to guardian.
In the present embodiment, step 101 specifically comprises:
First the dictionary of four classes and adolescent psychology pressure correlation is constructed, as described in Table 1, comprising:
(1) pressure type dictionary (comprising 399 vocabulary), has wherein divided four kinds of typical pressure type, that is, school work pressure, human communication pressure, emotion pressure and autognosis pressure type.
(2) negative emotions dictionary (comprising 250 vocabulary), such as, detest, boring, dejected, hate, dislike, fear, painful, miserable, sad etc.
(3) degree dictionary (comprising 219 vocabulary), is divided into five degree ranks, that is, very gently, light, medium, by force, very strong.
(4) negate dictionary (comprising 18 vocabulary), e.g., not, non-, no, without etc.
Table 1 four class dictionary
Secondly; based on above-mentioned dictionary; obtain the feature that several are relevant to psychological pressure, comprising: the Color Emotion in the number of the number of the number of the contact of grammer between pressure type and negative emotions word, Negative sentiments word, front emoticon and negative emoticon, exclamation mark and question mark, emotion rank, the music style shared, normal or improper microblogging issuing time, normal or improper issue frequency and image.Specifically:
(1) the grammer contact between pressure type and negative emotions word is obtained.
For each sentence pushed away in literary composition, use a kind of Chinese parsing device of graphic based, obtain the association word combination pushed away in literary composition in each sentence; The vocabulary association tree oriented according to all association vocabulary combination producings one, each node in tree represents a vocabulary, and the every bar limit between two nodes represents a vocabulary association.If there is a paths between a pressure type relative words node and a negative emotions lexical node, and in path, do not occur negating vocabulary, then think and detect corresponding pressure type.
For example, teenager user Xiao Ming write in microblogging: " achievement disorderly met with, false friendship, my world is very sad ".Chinese vocabulary relevance tree as shown in Figure 2 can be obtained after Chinese syntax analyzer analysis.In this example, there are two groups of word combinations (" achievement ", " disorderly meeting with ") and (" friendship ", " sham "), more or less can be reflected in the pressure type of school work and human communication aspect.Path is the number on limit in whole path, represents the language tightness degree between two vocabulary.Wherein, the paths of two groups of association vocabulary are 2, in order to the contribution margin of standardization different characteristic, with a mapping function, path are mapped as an integer in [1,6] herein, and wherein 1 ~ 6 corresponds respectively to six kinds of different pressure ranks.That is, path [0,3] is mapped as 5, (3,5] be mapped as 4, (5,10] be mapped as 3, be greater than 10 be mapped as 2,0 is mapped as 0.In addition, if there is some negative emotions vocabulary and pressure type vocabulary in sentence, but there is not path between them, then mapping value is set to integer 1.
First push away from original the vocabulary that the content of literary composition, retrieval is relevant to pressure type, if do not found, then what turn the forwarding of retrieval teenager user pushes away literary composition, herein, assuming that teenager has and is forwarded the same or analogous viewpoint of authorship, the emotion that push away literary composition.If all do not found, then by this, the pressure type pushed away in literary composition is set to NULL, and degree of pressure is set to " without pressure ".
(2) number of Negative sentiments word.
Negative sentiments word can reflect teen-age negative emotions, and the number of Negative sentiments word can as of a degree of pressure good measurement index.The number of the negative emotion word herein pushed away in literary composition is mapped on the integer between [0,5], if the number of negative emotion word is in the scope of 0 ~ 5, mapping value also should be 0 ~ 5 mutually; If the number of negative emotion word is greater than 5, then mapping value is 5.
(3) number of front emoticon and negative emoticon
Positive/negative emoticon is generally used for good/bad mood expressing someone.Researcher's negative emoticon number pushed away in literary composition is mapped as an integer between [0,5], the number of front emoticon is mapped as an integer between [0,15].Herein, the mapping policy similar to above-mentioned negative emotion word is taked.
(4) number of exclamation mark and question mark
The special punctuation mark such as exclamation mark and question mark is often used in microblogging by teenager, shows emotion.Exclamation mark is usually used to express some extreme moods, such as anger, complaint etc.; Question mark is usually used to the emotion expressing some confusion.The mapping policy used in eigen is the same.
(5) emotion rank
Article one, the emotion rank pushed away in literary composition illustrates the intensity of emotion." I extremely hates simple sentence such as! ! ! " just belong to a kind of high level emotion intensity, because wherein contain adverbial word " extremely " and 3 exclamation marks.Here, 5 kinds of elements have been considered, respectively: negative emotion word, degree adverb, negative emoticon, exclamation mark and question mark.First, add up one respectively and push away in literary composition the number comprising these 5 kinds of elements.Then, utilize formula ED=(NNegEmoticon+NNegEmotionWord+NAdvDegree+1) * (NExclamation+NQuestion+1) to calculate this and push away civilian emotion rank.Wherein, ED represents emotion rank, NNegEmoticon represents the number of negative emoticon, NNegEmotionWord represents the number of negative emotion word, NAdvDegree represents the number of degree adverb, NExclamationMark represents the number of exclamation mark, and NQuestionMark represents the number of question mark.Finally, the result (for being more than or equal to the integer of 0) of ED is mapped in certain integer of [0,5].Mapping policy is: if ED=0, and mapping value is 0; If ED ∈ (0,3], mapping value is 1; If ED ∈ (3,6], mapping value is 2; If ED ∈ (6,10], mapping value is 3; If ED ∈ (10,20], mapping value is 4; Other situation, then mapping value is 5.
(6) music style shared
Sentimental music delivers the emotion of certain sadness, and therefore, many teenagers being in pressure state like on microblogging, sharing sentimental music, to express the low mood of heart.Therefore it can be used as one for detecting the feature of adolescent psychology pressure.
(7) normal or improper microblogging issuing time
From macroscopic perspective, the time of teenager's issuing microblog is completely random.But from microcosmic angle, the time of each teenager's issuing microblog is relatively-stationary.Such as, teenager usually can in one's spare time instead of class period issuing microblog, and they prefer at frequent updating microblogging holiday.When they abnormal time point issue one push away literary composition time, this pushes away literary composition and is exactly probably one and pushes away literary composition especially with special emotion.In the present invention, we have done such hypothesis, if teenager has issued at the abnormal time point of regular working day push away literary composition, then think that he may be provided with certain anxious state of mind; If teenager has issued at the abnormal time point of weekend or holiday and pushed away literary composition, then think that this is normal, because most of teenager can be different from daily custom usually in the behavior of holiday.In view of above hypothesis, two following rules are formulated: if a) certain teenager user has been issued one at the abnormal issuing time point of routine work day and pushed away literary composition, then the issuing time eigenwert this pushed away corresponding to literary composition is set as 1, otherwise is set to 0; If b) teenager user has been issued one at the abnormal issuing time point of weekend or holiday and pushed away literary composition, then ignore.In this algorithm, weekends all in 1 year and public holiday are all taken into account.Because the custom of each teenager's issuing microblog is different, unified abnormal issuing time point therefore cannot be obtained.In this research, we for unit, locate abnormal issuing time point (herein, only consider routine work day) for individual with " day ".
1, add up certain teenager and issue the total number pushing away literary composition, stored in variable NUM.
2, corresponding 24 points will be divided into by 24 hours every day.Every bar is pushed away literary composition according to its time devided modulation issued to corresponding point, add up that each point pushing away civilian quantity, and stored in array numHour [i], wherein, i is array index, and its value corresponds respectively to 24 points from 1 to 24.
3, calculating mean value NUM/24, stored in variable avgNum.For each some i, if numHour [i] <avgNum/2 or numHour [i] >avgNum*2, then this time point i is regarded as the abnormal issuing time point of this user, and the issuing time this pushed away corresponding to literary composition (is labeled as 1 corresponding to putting i) eigenwert, otherwise is 0.
(8) normal or improper issue frequency
Similar with the time of issuing microblog, in general, the issue frequency pushing away literary composition also presents randomness, and has nothing to do in psychological pressure.But, in fact, when the microblogging that certain teenager issues than usual many a lot of or few a lot of time, he is likely in certain pressure mood.Therefore, we devise following scheme, for the issue frequency that notes abnormalities from teen-age overall microblogging.
1, add up certain teenager and issue the total number pushing away literary composition, stored in variable NUM.
2, total number of days (push away literary composition from the Article 1 issued and push away literary composition to the last item) of issuing microblog is added up, stored in variable N.
3, calculating mean value NUM/N, stored in variable avgFrequency.
That 4, adds up j issue every day pushes away civilian number, and time span is the release cycle of whole microblogging, and stored in array numFrequency [j], wherein, j is array index, and value corresponds to date j.
If 5 numFrequency [j] <avgFrequency/2 or is numFrequency [j] >avgFrequency*2, then the microblogging in jth sky is issued frequency and be considered as exception, and the eigenwert of each the issue frequency pushed away corresponding to literary composition issued in jth sky is labeled as 1, otherwise be 0.
Identical with issuing time, if the literary composition that pushes away of certain frequency anomaly is published on weekend or holiday, then this is pushed away literary composition and be considered as normally, namely frequecy characteristic value is 0.
(9) Color Emotion in image
Image can express the such as emotion such as excited, sad, and Experiment of Psychology is also verified, and color theme plays a part very important for emotion recognition.We use emotion Image Classfication Technology, weigh the emotion of piece image from five Angel of Aesthetics.These five Angel of Aesthetics comprise five colors combination, saturation degree, brightness, changes in temperature color, light and shade color.The result of image color emotion is mapped to one in Art Design field by the image scale space of the two-dimensions extensively approved (" cold-warm " and " strongly-soft ") by us.
The method and system present embodiments providing a kind of adolescent psychology pressure detection based on microblogging and dredge, by carrying out detection analysis to the civilian content that pushes away of microblogging, obtaining teen-age pressure type and degree of pressure, and carrying out online dredging and linking up in time.Carry out perception in conjunction with microblog and help the teen-age psychological pressure of release, having very large benefit to teen-age psychological education.
As shown in Figure 5, Fig. 5 shows the structural representation of the adolescent psychology pressure detection based on microblogging that one embodiment of the invention provides and the system of dredging, and this system comprises: characteristic extracting module 501, pressure detection module 502, pressure polymerisation module 503 and pressure dredge module 504.
