Description

TECHNICAL FIELD [0002] User equipment, control method thereof, and computer readable medium having computer program recorded thereof

The present invention relates to a user device, a method of controlling the same, and a recording medium in which a computer program is recorded, and in particular, a user device for extracting emotional information on a consumption object and providing information on the consumption object in a form that is easy for a consumer to recognize, It relates to a control method and a recording medium on which a computer program is recorded.

In recent years, as the spread of wired/wireless communication services such as mobile communication or high-speed Internet has become popular, almost all things in daily life that have been done offline in the past can be replaced by the use of the Internet. For example, commerce to buy and sell goods, the press to announce new news, and social social activities such as meeting and talking with friends can be the same on the Internet.

The biggest advantage of the Internet is the efficiency that time and space constraints are minimized and all tasks can be handled quickly and conveniently in one place.

On the other hand, one of the factors that significantly influence the user's judgment about information on the Internet is the opinions of other users. This can buffer the information provided unilaterally.

For example, when shopping on the Internet, a user determines whether to purchase a product while viewing information such as a description and image of a desired product. At this time, the user reviews the reviews of other users who have already purchased the product. Often, you read and decide whether to buy. In other words, if the product reviews left by other users are positive, the judgment tends toward purchasing the product. Conversely, when the product reviews are negative or there are no product reviews, the product purchase tends to be withheld even though the product is attempted to purchase.

Because sellers who sell products are also well aware of this trend, most Internet shopping malls currently have a product review and viewing area in the form of a bulletin board at the bottom of the web page describing the product. .

As such, user opinions on the Internet are one of the important parts that help to improve objectivity and reliability of information by buffering unilateral information.

However, there is a limitation in collecting user opinion information about the target product or service. For example, there is a hassle of having to search and search for reviews and reviews written by other users. In addition, if the amount of reviews, reviews, etc. written by other users is vast, the consumer may make a mistake of missing important decision-making factors.

The'sensibility analysis' described here recognizes the existence of the emotion and opinion expression expressed by the author of the text in the given text of the document to be analyzed, analyzes whether the expression is positive or negative, and analyzes the emotion/opinion expression. It refers to a function that detects an object in text and provides a pair of emotion/opinion expressions with the corresponding object. For example, given the text "Samsung PAVV 7000 has a good design but poor quality", the author's emotion/opinion information such as "The design is good" and "The picture quality is poor" is extracted by the emotion analysis. It is analyzed that it is a positive opinion that "the design is great" and a negative opinion that "the quality of the image is poor." In addition, the sentiment/opinion information may be finally determined that the information is for "Samsung PAVV 7000", and the result may be output.

In the present invention, elements extracted during sentiment analysis based on the given example can be defined as follows.

For example, assuming that there is a sentence such as "Samsung PAVV 7000 has good design, but poor quality" in the document to be analyzed, "design is good (positive)" and "deteriorated image quality (negative)" as emotion/opinion information. It can be obtained, and the elements extracted during the sentiment analysis are shown in Table 1 below.

Component Contents example Key word (Object) Subject of sentiment analysis "Samsung PAVV 7000" Property (Feature) Object of expression in sentiment analysis "Design", "Quality" Expression Positive or negative evaluations or opinions on attributes "Great", "Fall" Positive/Negative (Polarity) A value indicating whether the expression is positive or negative and its strength Strong negative: -2
Weak Negative: -1
Weak Positive: 1
Strong positives: 2

As shown in <Table 1>, the elements extracted during sentiment analysis are the main words, attributes, expressions, and positive/negative values, and these elements will be referred to as'emotional data' in the present invention. The subject word is the object of emotional expression, and the attribute indicates the personality, nature, and characteristics of the subject word, and becomes the object of expression. Expression represents the evaluation of positive or negative opinions on the attribute of the subject word. The positive/negative value is a value indicating whether an expression is positive or negative and its intensity. In <Table 1>, positive/negative values are expressed in integer types from -2 to +2. Negative numbers indicate negative, positive numbers indicate positive, and magnitude of absolute value indicates positive/negative strength. The positive/negative intensity referred to herein refers to the intensity of emotion/opinion expression, and is defined as being classified into “general sensibility” and “strong sensibility” in the present invention. "General sensibility" is a general form of expression that expresses emotion/opinion, and is a basic form such as "excellent", "falling off", "good", and "bad". "Strong sensibility" refers to expressions for the author to further emphasize the sensibility of the positive/negative in expressing the positive/negative. The method for expressing "strong sensibility" can be divided into two types, and the first is a method of expressing using adverbs of degree/intensity. For example, the emotional/opinion information that "I like the design" If there is, you can add a degree/strength adverb such as "I really like the design" or "I really like the design" to express a strong sensibility. Another way is that the expression itself expresses a strong emotion. For example, in expressing the sensibility of "good", expressions such as "awesome" and "best" can be seen as expressions of strong emotion.

The apparatus for emotional analysis according to an exemplary embodiment of the present invention defines the emotional/opinion constituent elements as above and extracts a set of defined constituent elements. In the present invention, the knowledge of the emotion analysis system is managed by a dictionary, which is referred to as a'sensibility dictionary'. The emotion dictionary has the previously defined attributes and expressions, and the positive/negative values corresponding to the attribute and expression pairs. These emotion dictionaries are built independently for each predetermined category. The reason why the emotional dictionary should be constructed for each category is that the set of attributes of the subject word group included in each category is different. For example, an attribute of "shutter speed" is an attribute commonly used in a "camera" product set, but is a concept that does not exist in a product set such as "refrigerator" and "diaper." If these attributes are used without distinction of categories, not only errors will be caused, but also the management of the emotion dictionary will not be efficient, and soon the performance of the emotion analysis system will be degraded.

The categories of the emotion dictionary have a tree structure and have multiple levels. 1 is a diagram illustrating a tree structure of categories of an emotion dictionary according to an embodiment of the present invention.

As shown, the categories of the exemplary emotion dictionary are configured in a multi-depth tree structure. According to an embodiment of the present invention, the highest category is referred to as a domain, and may have three domains, for example, "person", "place", and "product".

The structure of categories below the domain is divided into sub-categories according to the characteristics of the parent node (upper category), and the lowest category is composed of the most subdivided population in the domain. Meanwhile, a set classified within a hierarchical category is defined as a taxonomy of a hierarchical category.

1 shows an example of the structure of a sentiment category for a "product" domain.

Each category is independently composed of entries of attributes and expressions, but there are entries that are commonly used among similar categories. For example, assuming that “DSLR camera” and “camcorder” are in the same level category, both “DSLR camera” and “camcorder” categories may have a property of “liquid crystal” in common. In this case, if the attribute "liquid crystal" is managed for each category, the amount of emotional data becomes unnecessarily large, and efficiency is degraded, such as separately managing expressions for the corresponding attribute. In this case, according to an embodiment of the present invention, common emotional data of each category is integrated into a higher category and managed, and at the time of actual emotional analysis, the emotional data of the upper category to which the corresponding category belongs can be inherited and used. have.

In summary, the sentiment analysis according to an embodiment of the present invention can be said to be a process of registering sentiment data including a subject word, attribute, expression, and positive/negative values for each category in the sentiment dictionary classified into a tree structured category. .

In addition, the'classification information' described herein refers to additional information for classifying an emotion analysis object. For example, the classification information may include category information of an emotion analysis object, brand information of an emotion analysis object, and manufacturer information of an emotion analysis object.

Here, the category information refers to information indicating in which hierarchy the emotion analysis object exists in a category of a tree structure. In addition, the brand information refers to the brand representing the emotion analysis object. In addition, the manufacturer information refers to the manufacturer that manufactures the emotion analysis object.

Classification information may be added and registered in the process of registering emotion data in the emotion dictionary by the emotion analysis process.
