Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

In order to reduce the risk inherent in the purchase of the product, consumers are asked to decide whether to purchase the product based on the purchasing history of the purchaser.

In this regard, a system (Sky Scanner, http://www.skyscanner.co.kr) that analyzes product review data and provides evaluation results is actively underway. They are being studied / developed in various fields such as lodging, movies, books, cosmetics, and TV commercials.

In the present invention, a system for analyzing and evaluating an electronic commerce product (product) is designed, and a review sentence emotion analysis technique is proposed through emotion dictionary construction that reflects characteristics according to attributes and classification of products.

In particular, in one embodiment of the present invention, we propose a configuration that may be more suitable for use in analyzing the review of the book.

According to the National Survey of National Readings by the National Statistical Office, 28.7% of adults decide whether to buy a book, and 71.3% reflect external opinions such as recommendation of people around, bestseller rankings, and external reviews. That is, the majority reflect external opinions on whether or not to buy books. According to a survey by the National Statistical Office (KNSO), 74.8% of offline bookstores, 22.3% of Internet bookstores, and 2.9% of other books were purchased. As a result, there is a need for a system that provides a mobile-based system that can classify and analyze book reviews, which are representative external opinions, so that they can be quickly and easily identified in offline bookstores. However, most of the systems in the mobile application provide users with simple information about their books, such as authors, publishers, etc., or provide unclassified / unreviewed reviews, so that users can read hundreds of reviews There is a difficulty. Therefore, we collect reviews of each book, analyze the positive / negative emotion trends of the review, and provide the results according to the evaluation criteria of the book. Through this, we can decide the purchase decision of the user, Is required.

Accordingly, in an embodiment of the present invention, a review is collected from a bookstore server or the like, which can be operated by a medium-sized bookstore, and a logic for reviewing a book and recommending a book based on the review is proposed .

2 is a diagram showing a conceptual diagram of a system 10 according to an embodiment of the present invention. 3 is a flowchart illustrating an analysis method of a system according to an embodiment of the present invention.

FIG. 4 is a conceptual diagram for analyzing review data 400-1, 400-2,... According to an embodiment of the present invention.

Referring to FIG. 2, the review analysis system 10 according to an embodiment of the present invention may include a mobile terminal 100 and a server 200. At this time, the mobile terminal 100 can exchange data with the server 200 through the wireless communication unit 110. Also, the user can receive input or provide an output to the user 11 through a user interface output through the touch screen 151. At this time, the user interface may be provided in the form of an application executed in the mobile terminal 100.

2, a case where the mobile terminal 100 and the server 200 are separately provided has been described. However, when the memory 170 of the mobile terminal 100 itself is connected to the server 200, You might be able to perform some or all of the roles.

In step S301, the control unit 180 can identify the book. At this time, the specification of the book may be input to the user's product search keyword (keyword for specifying the book) through the user interface, and the book may be specified based on the product search keyword. Alternatively, the user may output a product list including a plurality of product items, and receive an input for selecting one on the product list to specify the product. Meanwhile, the embodiment of the present invention is not limited to the method of specifying the product, but will be included in the embodiment of the present invention as long as any one product can be specified.

In step S302, the controller 180 may receive the review data 400-1, 400-2,... For the specified book from the predetermined server 200. FIG. At this time, the predetermined server 200 may be a server managed / operated / used by a middle / large-sized bookstore, or may be connected to a server by specifying an IP address by a world wide web, You will be able to include all the servers you have.

It is assumed that the first and second review data 400-1 and 400-2 shown in FIG. 4 are reviews for the same book.

In step S303, the control unit 180 extracts key words, modifiers, and emphasized words from the review data.

According to the example shown in Fig. 4, the first review data 400-1 describes "the configuration is very robust ". The control unit 180 according to the embodiment of the present invention extracts from the first review data 400-1 a keyword called " configuration 401-1 ", an emphasis word "very 402-1" -1) ".

Concrete methods of extracting this way will be described below.

On the other hand, the same product (book) may be superior in certain attributes but not in other attributes. For example, the price of a book may be inexpensive (affirmative), but it may be insufficient in the composition of a book. Accordingly, in one embodiment of the present invention, the degree of positive and negative is measured differently for each attribute category, and the degree of affirmative negative is determined for each user who views the category.

At this time, in one embodiment of the present invention, the attribute is determined using the extracted key word.

That is, the control unit 180 can determine / set the attribute category based on the extracted key words 401-1, 401-2, ... in step S304. In particular, when determining the attribute category in step S304, the control unit 180 determines whether the keyword is positive or negative based on a modifier among the extracted key words 401-1, 401-2, You can only set it as an attribute category. At this time, the modifier may be limited to the case where the modifier is formed in the same sentence as the keyword.

For example, as shown in FIG. 4, in the first review data 400-1, the key word "configuration 401-1" is referred to as " ) &Quot;, it is possible to determine " configuration 401-1 "as an attribute category because it can be judged as positive or negative. However, if other review data say that "lessons seem to reflect a lot of the artist's values," we can extract the key word "lesson," but we can extract a modifier that "teaches" Otherwise, the control unit 180 may not set the attribute category for the keyword "Lesson learned ". The keyword that can be set in the attribute category in this way, that is, a positive or negative determination, is called an evaluation keyword, and the remaining keywords are called a theme keyword. That is, the evaluation key word refers to a key word (recognition, composition, difficulty, etc.) capable of evaluating affirmative or negative, and the theme key word may mean a word (mathematics, textbook, etc.) .

The data extracted from the review data as described above will be referred to as analysis data. The first analysis data 410-1 may be obtained from the first review data 400-1 and the second analysis data 410-2 may be obtained from the second review data 400-2. (401-1) " corresponding to "configuration 401-1" based on the analysis data having the "configuration 401-1" which is the same key word among the analysis data 410-1, The graph 404-1 can be drawn.

Referring to the graph 404-1, considering all of the plurality of analysis data 410-1, 410-2, ..., the ratio of positive review among all 100% percentages is 70% The percentage of negative reviews is 30%.

In an embodiment of the present invention, it is further proposed to further display the representative positive key word 405-1 in the positive region and the representative negative key word 405-2 in the negative region. This is to inform the user who browses the graph 404-1 of what reason is positive and becomes negative. The representative positive key word 405-1 may be a modifier that is included most among a plurality of positive reviews. Likewise, the representative negative key word 405-2 may be a modifier that is included in the plurality of negative reviews among the plurality of negative reviews. That is, in the illustrated example, according to the review data written by the other people, positive reviews are created because the constitution is solid through the representative positive key word 405-1, and the positive negative key word 405-2 This is insufficient, so you can see that negative reviews have been written.

5 is a diagram illustrating a review analysis graph 502 for a plurality of attribute categories 501 for a particular book, according to one embodiment of the present invention. Referring to FIG. 5, the first graph 404-1 shown in FIG. 4 includes a first graph 404-1 for an evaluation key word "Configuration 401-1 ", and the first graph 404-1 ) Are shown together with other graphs shown for other evaluation key words. Thus, the user can grasp the characteristics of the book at a glance by the review analysis graph which is individually output for each evaluation keyword.

In the drawing, a review analysis graph 502 showing the ratio of the positive and negative referential rates according to the product evaluation key words of the book to the X and Y axis values is shown. FIG. 5 is a result of a review analysis graph 502 of a book called 'conceptual mathematics 1'. In the review analysis graph (502), evaluations such as 'awareness', 'summary', and 'composition' are positively evaluated, and 'evaluation of difficulty' and 'type' are somewhat negatively evaluated. In terms of the positive evaluation, "positive", "good" and "difficulty-appropriate" are represented as representative positive key words (405-1) Too difficult "and" problem - sorry "were analyzed as the representative negative keywords (405-2).

According to the above description in Fig. 4, a method of extracting emphasis and modifiers and a method of displaying a graph based on both of a plurality of analysis data have been described. One embodiment of such a method will be described in detail below.

In an embodiment of the present invention, it is proposed to construct a database of modifiers and emphasized words, extract them, and point out the results of them to show a graph.

The following Tables 1 and 2 illustrate examples of the modifier database and the emphasis word database, respectively, according to an embodiment of the present invention.

Modifier Positive / negative sign value
(pos_neg) Point (W _MS ) lie -One 10 Liar -One 10 Georgia -One 10 Cowardly -One 10 Rough -One 10 coarseness -One 10 The -One 10 worry -One 10 health -One 10 Skip -One 10 Prevent the gun -One 10 Dry One 10 Sturdy One 10 ... ... ...

Emphatic Weighting (W _ES ) Metallurgy metallurgy One slightly 0.5 Coolly 0 Full 1.5 Without fail One A fool One Suddenly One Which 0 Dimly 0.5 Difficulty One Bewilderment One Bite water 0.5 A little 2 hurry One ... ...

If there is a word included in the modifier database, the control unit 180 can determine that the word is a modifier. Similarly, if there is a word included in the emphasis word database, the control unit 180 can determine that the word is an emphasis word.

Accordingly, in step S303, the controller 180 may extract the modifiers or emphasized words by collating the review data on morpheme units, and then collating the cleaved morphemes against the modifiers and the emphasis word database, respectively.

On the other hand, each word included in the modifier database is provided with positive / negative signs and points indicating affirmation / negation. The positive / negative sign value may have a value of +1, -1, or 0, as shown in Table 3, depending on the nature of the word. That is, when the sign value is multiplied by a specific value, the result will be a positive number if positive, and a negative number if negative. Furthermore, in an embodiment of the present invention, in the case of a modifier that can not determine whether or not it is positive or negative, it is proposed to have a neutral value of zero.

Affirmation / denial Positive / negative sign value Positive +1 denial -One neutrality 0

In the example of the modifier database prepared in Table 1, each point (W _MS ) is fixed to 10, but it is obvious that it is possible to have different points for each word.

On the other hand, in an embodiment of the present invention, it is proposed to calculate a positive or negative reference as a numerical value indicating the degree of affirmation or negative, and to output a result screen (for example, a graph or the like) based thereon.

We propose that each point of the modifier is multiplied by the weight (W _ES ) of the emphasis word. For example, if the modifier of "good" is 10 points and the weight of the word "very" in the data of "very good" is 1.5, then the affirmative point for the data in which the modifier and the emphasis are combined is 15 points Lt; / RTI >

Accordingly, the affirmative point (S _PS ) for the specific analysis data can be calculated as shown in the following Equation (1).

At this time, the affirmative point (S _PS ) will mean the score when the sign value is +1.

If the sum of the affirmative points (S _PS ) of the analysis data belonging to the specific attribute category is the affirmative referencing (S _PT ) of the attribute category,

.

If the negative point S _NS is defined in contrast to the affirmative point S _PS described above, it can be calculated by the following equations (3) and (4).

At this time, the negative point (S _NS ) will mean the score when the sign value is -1.

If a value obtained by adding together the negative points (S _NS ) of the analysis data belonging to the specific attribute category is the negative reference (S _NT ) of the attribute category,

When calculating the positive referential degree (S _PT ) and the negative referential degree (S _NT ) in the specific attribute category calculated by the above Equations (1) to (4), the ratio of positive and negative for the entire 100% A graph 404-1 for a particular attribute category may be shown. If there are a plurality of attribute categories, the above process (a process of obtaining affirmative / negative reference) for each attribute category may be repeated.

On the other hand, in an embodiment of the present invention, a keyword having a high number of times of mention (for example, the top 30 keywords) is extracted from the review data of a specific product, and a word cloud ).

6 is a diagram illustrating an example of a word cloud 601 based on a keyword according to an embodiment of the present invention.

The word cloud (601, word cloud) is a combination of key words with a high frequency of mention, and when outputting each key word, the letter size can be displayed differently according to the number of times mentioned. For example, the keyword "concept 603" has been mentioned 100 times, and the keyword " lecture 604 "has been mentioned 10 times. On the output word cloud 601, May be output larger than the keyword "lecture 604" (see Fig. 6).

That is, the control unit 180 outputs a combination of key words having a high number of times of mention, and the size of each keyword output may be proportional to the number of times of mention.

At this time, in another embodiment of the present invention, the word cloud 601 can be composed of only the theme keywords except for the evaluation keyword. In other words, the user can analyze a review of the evaluation keyword at a glance through the positive / negative ratio provided through the review analysis graph 502 described with reference to FIG. 5, and the word cloud 601 ) Can be analyzed at a glance with a review of the theme core.

Meanwhile, in an embodiment of the present invention, when a part of the extracted key words (evaluation key words, theme key words) is selected, it is suggested to recommend a book related to the selected key word.

For example, if the evaluation key word "configuration 401-1" is selected by the user, a positive comment (S _PT ) on the evaluation key word "configuration 401-1" You will be able to print a list of the top ten books on the mentions, sorted by affirmation.

7 is a diagram illustrating an example of outputting a list of books associated with a keyword selected by a user according to an embodiment of the present invention.

Referring to the drawing, a theme key word selection region 701 and an evaluation key word selection region 702 are outputted. A list of a plurality of theme key words is output in the theme keyword selection area 701 and a list of evaluation key words is similarly output on the evaluation key word selection area 702. [

Such theme key words or evaluation key words may be words automatically extracted from the review data by the method described above.

If the user selects the "book for day trip" on the theme keyword selection area 701, the control unit 180 can search for the book having the theme keyword "day trip" and output it to the book list 703 will be.

If a specific evaluation key word is selected on the evaluation key word selection area 702, for example, a keyword of the configuration 401-1, the control unit 180 displays the configuration 401-1 on the output book list 703, The user can control to sort the output book list 703 on the basis of the positive reference (S _PT )

If a plurality of evaluation key words are selected on the evaluation key word selection area 702, the control unit 180 determines whether or not the evaluation keyword terms are selected based on the sum of the positive reference scores (SPT) of the selected plurality of evaluation keywords The book list 703 can be sorted.

For example, if the configuration, description, image, and author are selected as in the example shown in FIG. 7, the control unit 180 determines the positive references S _PT 1, S _PT 2, S _PT 3, and S _PT 4, as shown in FIG.
