[0027] The present application provides an old-age tourism product and experience behavior analysis management system based on big data.

[0028] As shown in the accompanying Figure 1 In an embodiment of the old-age tourism product and experience behavior analysis management system based on big data according to the present application, the old-age tourism product and experience behavior analysis management system based on big data comprises a user terminal (a smart terminal operated by a user participating in tourism, such as a smart phone), a management terminal (a smart terminal used by a management personnel of a tourism operation unit, such as a personal computer), and a server; the user terminal and the management terminal are both communicatively connected to the server; the user terminal is configured to: acquire feedback content input by a user for a tourism product, wherein each tourism product is correspondingly provided with a unique and different product number (to identify each tourism product and feedback content submitted subsequently for different tourism products), and the feedback content is in a text format or an audio format (i.e., the user can submit the feedback content in the form of manually inputting text, or can submit the feedback content in the form of recording audio); establish a corresponding relationship between the feedback content and the product number of the tourism product to which the feedback content corresponds; and send the feedback content and the corresponding product number to the server.

[0029] The server is configured to: when the feedback content is in a voice format, perform voice recognition and sentence segmentation processing on the feedback content to obtain corresponding text sentences (by performing voice recognition and sentence segmentation processing on the feedback content in an audio format to obtain text sentences corresponding to the feedback content, wherein the text sentences are generally multiple); when the feedback content is in a text format, perform sentence segmentation processing on the feedback content to obtain corresponding text sentences; obtain a tourism project word library and an emotional evaluation word library; perform word recognition on the text sentences based on the tourism project word library and the emotional evaluation word library, and generate an emotional score value corresponding to the feedback content (in this embodiment, the emotional score value has a value range of [1, 10]), wherein the higher the emotional score value, the more positive the user's experience evaluation of the tourism product, that is, the higher the user's evaluation of the tourism product and the better the experience; and package and send the feedback content, the corresponding product number and the emotional score value to the management terminal.

[0030] The management terminal is configured to: display the feedback content, the corresponding product number and the emotional score value, so that the management personnel can analyze and optimize the tourism product according to the feedback content and the corresponding emotional score value.

[0031] The old-age tourism product and experience behavior analysis management system based on big data can solve the problem that current old-age tourism products lack effective analysis means for experience and feedback information of old-age tourists in a tourism process. In specific use, a user terminal obtains feedback content input by a user for a tourism product, and then sends the feedback content to a server. According to the format of the feedback content, corresponding processing is performed to obtain text sentences corresponding to the feedback content, wherein the text sentences are judgment text evaluation content of the user for the tourism product and have been subjected to sentence segmentation processing, which is more convenient for subsequent emotional analysis. The server performs word recognition on the text sentences based on a tourism project word library and an emotional evaluation word library, and generates an emotional score value corresponding to the feedback content. The emotional score value can reflect the evaluation of the user for the tourism product. Subsequently, the management terminal displays the feedback content, the corresponding product number and the emotional score value, so that the management personnel can analyze and optimize the tourism product according to the feedback content and the corresponding emotional score value, thereby further improving the tourism experience of the user. As can be seen from the above, the technical solution of the present application can effectively collect experience and feedback information of tourists in a tourism process, and can also perform emotional analysis and scoring on the collected experience and feedback information, so that subsequent targeted optimization can be performed.

[0032] In addition, the user terminal comprises a microphone and a first display module (e.g. a touch display screen); the first display module is configured to generate a feedback submission page, wherein the feedback submission page comprises a page header area, a text input area and a voice input button, the page header area is configured to display the name and product number of the tourism product currently being fed back, and the text input area is configured to fill in the feedback content in the form of text; the microphone module is configured to obtain the feedback content in the form of audio spoken by the user when the voice input button is triggered.

[0033] Meanwhile, the server is further configured to: when the feedback content is in the form of audio, perform voice recognition on the feedback content to obtain corresponding voice text; obtain and traverse the interval duration between each two adjacent voice texts, and when the interval duration between the two adjacent voice texts is greater than a first preset duration (the normal speaking speed is 200-260 words, and in this embodiment, 240 words per minute, i.e. the interval duration between each word in a normal sentence should be less than 0.05 seconds, and the pause interval duration between each sentence is generally about 0.2 seconds, so in this embodiment, the first preset duration is set to 0.2 seconds), mark the middle time between the two adjacent voice texts as a segmentation time (here, the segmentation time is the middle time between two adjacent sentences); segment the feedback content in the form of audio according to the segmentation time to obtain a plurality of voice segments; and take the voice text corresponding to each voice segment as the text sentence (i.e. one voice segment corresponds to one text sentence).

[0034] Specifically, generally speaking, each sentence corresponds to one matter when a person speaks, and in a tourism review, each sentence generally reviews a certain item (e.g. catering, transportation, accommodation and scenic spots) in tourism; the purpose of this embodiment is to show how to identify and segment the feedback content in the form of text and audio respectively to obtain the corresponding text sentence, which is more convenient for subsequent sentiment analysis.

[0035] In addition, the server stores the travel project word library and the sentiment evaluation word library. The travel project word library includes, but is not limited to, the following: scenic spot, scenic area, landscape, place, service, staff, service staff, attitude, tour guide, reception, price, cost, money, cost performance, accommodation, hotel, room, inn, restaurant, transportation, car, driver, distance, flight, train, catering, food, eating, meal, food, and restaurant. The sentiment evaluation word library includes, but is not limited to, the following: good, general, poor, excellent, beautiful, beautiful, magnificent, stingy, thoughtful, full, fast, slow, on time, friendly, polite, many people, few people, professional, amateur, low, appropriate, delicious, not very used to, good taste, too salty, and bad taste.

[0036] Each word in the sentiment evaluation word library is provided with an evaluation score for expressing the intensity of emotion (the value range of the evaluation score is consistent with the value range of the emotion score, and in this embodiment, is [1, 10]), and the higher the evaluation score, the more positive the corresponding sentiment evaluation word. Specifically, in this embodiment, the following can be used as examples: good (evaluation score is 8), general (evaluation score is 6), poor (evaluation score is 3), excellent (evaluation score is 9), beautiful (evaluation score is 8), beautiful (evaluation score is 8), magnificent (evaluation score is 9), stingy (evaluation score is 2), thoughtful (evaluation score is 9), full (evaluation score is 7), fast (evaluation score is 7), convenient (evaluation score is 8), slow (evaluation score is 4), on time (evaluation score is 8), relatively far (evaluation score is 4), friendly (evaluation score is 9), polite (evaluation score is 9), many people (evaluation score is 7), few people (evaluation score is 6), professional (evaluation score is 9), amateur (evaluation score is 2), low (evaluation score is 3), appropriate (evaluation score is 7), delicious (evaluation score is 8), not very used to (evaluation score is 4), good taste (evaluation score is 9), too salty (evaluation score is 3), and bad taste (evaluation score is 2).

[0037] The server is further configured to:

[0038] perform character recognition on the text sentence to obtain sentiment evaluation words and travel project words in the text sentence;

[0039] determine whether there are other travel project words after the i-th travel project word in the text sentence;

[0040] If so, mark the segment of words between the i-th tourism project word and the (i+1)-th tourism project word in the text sentence as the first segment of words to be analyzed corresponding to the i-th tourism project word; (If a tourism project word appears in the text sentence, then the segment of words between this tourism project word (the i-th tourism project word) and the next tourism project word (the (i+1)-th tourism project word) (i.e., the first segment of words to be analyzed) is highly likely to contain sentiment evaluation words for this tourism project word, and these sentiment evaluation words are valid evaluations for the i-th tourism project word, and need to be used to facilitate the subsequent calculation of sentiment score values).

[0041] If not, mark all text following the i-th tourism item word in the text sentence as the second segment to be analyzed corresponding to the i-th tourism item word (the second segment to be analyzed is likely to contain sentiment evaluation words for the i-th tourism item word, and these sentiment evaluation words are valid evaluations of the i-th tourism item word, which need to be used to facilitate the subsequent calculation of sentiment score); where 1≤i≤I, and I is the total number of tourism item words in the text sentence;

[0042] Determine whether there are sentiment judgment words in the first or second segment of words to be analyzed corresponding to the i-th tourism project word;

[0043] If they exist, establish a correspondence between the sentiment evaluation words in the first or second segment of words to be analyzed corresponding to the i-th tourism project word and the i-th tourism project word; calculate the sentiment score of the text sentence based on the sentiment evaluation words corresponding to the i-th tourism project word; calculate the sentiment score of the feedback content based on the sentiment score of the text sentence.

[0044] For details, see attached. Figure 2 As shown, attached Figure 2 The corresponding negative content includes three text sentences: "Convenient transportation", "Accommodation is relatively far away", and "Diet is not to my liking". It can be seen that: the first tourism item word in the first text sentence is "transportation", the corresponding second word segment to be analyzed is "convenient", and the emotional judgment word in the second word segment to be analyzed is "convenient"; the first tourism item word in the second text sentence is "accommodation", the corresponding second word segment to be analyzed is "relatively far away", and the emotional judgment word in the second word segment to be analyzed is "relatively far away"; the first tourism item word in the third text sentence is "diet", the corresponding second word segment to be analyzed is "not to my liking", and the emotional judgment word in the second word segment to be analyzed is "not to my liking".

[0045] Furthermore, the formula for calculating the sentiment score of the text sentence based on the sentiment evaluation words corresponding to the i-th tourism project words is as follows:

[0046] ,

[0047] In the formula, is the sentiment score value of the text sentence; is the evaluation score value of the i-th sentiment evaluation word corresponding to the i-th travel project word in the text sentence; 1≤i≤I, I is the total number of travel project words in the text sentence. , is the total number of sentiment evaluation words corresponding to the i-th travel project word.

[0048] Specifically, as shown in the following table, according to the above example, the sentiment score value of the first text sentence is 8; the sentiment score value of the second text sentence is 4; and the sentiment score value of the third text sentence is 4. Figure 2

[0049] The calculation formula for calculating the sentiment score value corresponding to the feedback content based on the sentiment score value of the text sentence is:

[0050] ,

[0051] In the formula, is the sentiment score value corresponding to the feedback content; is the sentiment score value of the j-th text sentence of the feedback content, 1≤j≤J, J is the total number of text sentences of the feedback content.

[0052] Specifically, the sentiment score value corresponding to the feedback content is obtained by taking the average value of the sentiment score values of each text sentence of the feedback content as the final sentiment score value corresponding to the feedback content.

[0053] In addition, the server is further configured to: every second preset time length (for example, 1 day), obtain all feedback contents received in the past second preset time length, and corresponding product numbers and sentiment score values, and mark the obtained feedback contents as to-be-displayed contents; package and send the to-be-displayed contents, and the corresponding product numbers and sentiment score values to the management terminal; and the management terminal is further configured to: display the to-be-displayed contents in order according to the sizes of the sentiment score values corresponding to the to-be-displayed contents.

[0054] Specifically, the to-be-displayed contents are displayed in order according to the sizes of the sentiment score values corresponding to the to-be-displayed contents, that is, the feedback content with a lower sentiment score value is displayed preferentially, thereby facilitating the management personnel to optimize the travel product.

[0055] ​​​Further, the management terminal comprises a second display module and a loudspeaker; the second display module is configured to generate and display an evaluation display page, wherein the evaluation display page comprises a first tab frame, a second tab frame and a content frame arranged in sequence from left to right, the first tab frame comprises a plurality of first tabs arranged in sequence from top to bottom, each first tab is configured to display a different product number, the second tab frame comprises a plurality of second tabs, each second tab is configured to display an emotional score value corresponding to each to-be-displayed content, and the second tabs are arranged in sequence from top to bottom in the order of the emotional score values displayed by the second tabs from small to large, when one of the first tabs is clicked to trigger, the emotional score values corresponding to each to-be-displayed content corresponding to the product number in the triggered first tab are displayed in each second tab, when one of the second tabs is clicked to trigger, the to-be-displayed content corresponding to the emotional score value in the triggered second tab is displayed in the content frame on the right, when the to-be-displayed content is in text format, the to-be-displayed content is directly displayed in the content frame, when the to-be-displayed content is in audio format, a play button is further displayed in the content frame, and when the play button is clicked to trigger, the to-be-displayed content in audio format is played through the loudspeaker.

[0056] Specifically, the evaluation display page is as shown in the accompanying drawings, which can clearly and clearly display the feedback content of a tourism product, and the second tabs are arranged in sequence from top to bottom in the order of the emotional score values displayed by the second tabs from small to large, so that the manager can preferentially process and analyze the feedback content with a lower emotional score value. Figure 2

[0057] Further, the user terminal is further configured to: when the obtained feedback content is in text format, generate a text image displaying the feedback content; perform encryption processing on the text image to obtain a corresponding encrypted image and decryption data; and send the encrypted image and the decryption data to the server in batches.

[0058] Specifically, in actual application, the feedback content input by the user may contain personal privacy information (such as the identity information of the staff during the tour, the identity information of the staff at the scenic spot, or even the identity information of the user), which is easy to be stolen during network transmission and cause privacy leakage; therefore, the feedback content is converted into a text image in image format, and then encryption processing is performed on the text image to obtain a corresponding encrypted image and decryption data; the encrypted image and the decryption data are sent to the server in batches; thereby avoiding the situation that the text image is stolen during network transmission and causes privacy leakage.

[0059] ​Further, the text image is in a rectangular shape; the user terminal is further configured to generate an adjustment circle with a radius greater than a preset value (set as 85% of the length of the shorter side of the text image) within the text image, wherein the center of the adjustment circle is the center point of the text image; establish a rectangular coordinate system in the text image, wherein the origin of the rectangular coordinate system is the center of the adjustment circle; evenly divide the adjustment circle according to a preset angle (e.g., 10°) to obtain a plurality of sector regions with the same area, and number the sector regions, wherein the lower straight line segment of the sector region numbered 1 coincides with the horizontal axis of the rectangular coordinate system, and the numbering of the subsequent sector regions increases in the counterclockwise direction, and the upper straight line segment of the sector region with the largest number coincides with the horizontal axis of the rectangular coordinate system; and obtain the encrypted image after performing M times of encryption adjustment operations on the text image, wherein each encryption adjustment operation is: randomly selecting two different sector regions, swapping the image contents of the two selected sector regions, and recording the numbers of the two selected sector regions to form a number group; sorting the number groups according to the order of generation to form a number set (the number of number groups in the number set is M); and taking the number set, the radius value of the adjustment circle, and the preset angle as the decryption data.

[0060] Specifically, by the above steps, the text image can be encrypted, so that the feedback content in the text image is no longer readable, and privacy information leakage is avoided; specifically, as shown in FIG. 8, an adjustment circle and a rectangular coordinate system are constructed in the text image, and then a plurality of sector regions are constructed in the adjustment circle; subsequently, the image contents of any two sector regions are randomly swapped to complete image encryption. Figure 3

[0061] ​Meanwhile, the server is further configured to: acquire the encrypted image and the decryption data sent from the user terminal and corresponding to each other; generate an adjustment circle in the encrypted image, wherein a radius of the adjustment circle is a radius value in the decryption data; establish a rectangular coordinate system in the encrypted image, wherein an origin of the rectangular coordinate system is a center of the adjustment circle; uniformly divide the adjustment circle according to a preset angle in the decryption data to obtain a plurality of sector regions with consistent areas, and number the sector regions, wherein a lower straight line segment of the sector region numbered 1 coincides with a horizontal axis of the rectangular coordinate system, the numbering of the subsequent sector regions is sequentially increased in an anticlockwise direction, and an upper straight line segment of the sector region with the largest number coincides with the horizontal axis of the rectangular coordinate system; reversely sort the numbering groups in the numbering set to obtain a new numbering set; and obtain the decrypted image after performing M times of decryption adjustment operations on the encrypted image, wherein before performing the mth decryption adjustment operation, a numbering group with a serial number of m in the new numbering set is marked as a target group, and the target group of the other numbering groups is removed, 1≤m≤M, and each decryption adjustment operation is: selecting two sector regions corresponding to the numbering in the target group, and swapping the image contents of the two selected sector regions.

[0062] Specifically, the encrypted image can be decrypted based on the decryption data through the above steps, and the operation idea is consistent with the above encryption idea, except that the order of the sector regions is swapped and the encryption process is reversed.
