The present invention relates to a topic presentation method, and more particularly, to a method of presenting a topic according to the other person, a device, and a computer program.
These days, there are more and more chances of having conversations with a plurality of users through blogs, Facebook™, Twitter™, Internet message boards and the like. In such an environment, there is a demand for presentation of a successful topic according to the other person in the conversation.
As is known in the art, JP2008-539528A by Lunt et al. discloses a technique of calculating compatibility scores of individuals on a social network based on compatibility of interests expressed by the individuals.
As is also known in the art, JP2010-277480A by Kengo et al. discloses a technique of searching for a person who is important to an arbitrary person, based on hobby information indicating the hobby of each person.
Also as is known in the art, JP2010-066814A by Kengo et al. discloses a technique of finding, among people in a specific relationship (for example, a circle of friends), a person who is familiar with a certain topic.
These conventional techniques are techniques for calculating rough relation or compatibility between individuals, and do not present techniques regarding what kind of topic would enable a more successful conversation with the other person.
The present invention is for presenting a topic according to the other person. The present invention is for presenting a related person according to the degree of liking. Another object is to present a topic map with respect to the other person. Another object is to present a human map with respect to the other person. Another object is to present a topic according to the degree of balance. Another object is to present a GUI (graphical user interface) with high usability for presenting a topic.
To solve the problem described above, the present invention provides a method of presenting a topic to a user by information processing by a computer including a storage device, the method comprising the steps of acquiring, and recording in a recording device, a related person who is connected to a user, acquiring, on a network, as conversation data, a comment of the user, a comment of each related person who is connected to the user, and a conversation between the related person and the user, extracting a topic from the conversation data, and recording the topic in the storage device, calculating a degree of balance of a topic with a related person, where a related person and a topic are read from the storage device, a value A of a degree of the user's liking to the related person, a value B of a degree of the user's liking to the topic, and a value C of a degree of the related person's liking to the topic are calculated, and a degree of balance V of the topic with the related person is calculated by using the A, the B, and the C, and presenting a topic based on the degree of balance.
Here, in the step of calculating a degree of balance, the degree of balance V is determined by V=A×B×C.
Alternatively, in the step of calculating a degree of balance, the degree of balance V may be determined by V=S×((|A|+|B|+|C|)÷3), where a sign of A×B×C is S (+1 or −1).
Preferably, the step of presenting presents, for each related person, a likable topic or a not very likable topic. Furthermore, the step of presenting presents a topic map according to a degree of balance and having a degree of the user's liking and a degree of the related person's liking as orthogonal axes. Here, the step of presenting may alternatively present a human map according to a degree of balance and having a degree of the user's liking and a degree of the related person's liking as orthogonal axes. Preferably, a step of displaying the related person or the topic in a hierarchical structure is further included.

Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings. In the following, description is given on a user interface, of a display device of a personal computer or the like, that uses a pointing device or the like, but the same thing can be said for operation on a touch display of a smartphone or the like by a finger.
The CPU 1701 is connected to each of the above-described pieces of hardware of the information processing apparatus 1 via the internal bus 1708, and controls the operation of each of the pieces of hardware, and also executes various software functions according to a computer program 100 stored in the storage device 1703. A load module is loaded into the memory 1702 at the time of execution of the computer program 100, and temporary data and the like generated at the time of execution of the computer program 100 are stored therein.
The storage device 1703 is a built-in fixed storage device, and is configured from a ROM or the like. The computer program 100 stored in the storage device 1703 is downloaded by the portable disk drive 1706 from a portable recording medium 90, such as a DVD or a CD-ROM, recording information such as programs and data, and is, at the time of execution, loaded from the storage device 1703 into the memory 1702 to be executed. In other embodiments, a computer program downloaded from an external computer that is connected via the communication interface 1707 may also be used.
The communication interface 1707 is connected to the internal bus 1708, and is capable of performing data exchange with an external computer or the like by being connected to an external network such as the Internet, LAN, WAN or the like.
The I/O interface 1704 receives input of data from external components. For example, in the case a touch panel is mounted on a display device 22, signals from the touch panel are received via the I/O interface 1704. Furthermore, the video interface 1705 is connected to the display device 22. A user interface, described in the embodiment, for presenting a topic according to the other person is displayed on the display device 22.
Furthermore, when a specific person B is selected on the GUI display unit 1610 from the related person list, a topic acquisition unit 1630 extracts into a list topics associated with the person A and the person B from conversation data recorded in the storage unit 1670. At this time, the liking calculation unit 1660 calculates the degrees of liking to the topics based on the conversation data, and adds the information to the topic list.
When the “degree of person A's liking to B”, the “degree of person A's liking to a topic”, and the “degree of person B's liking to the topic” are determined, a degree-of-balance calculation unit 1650 calculates the degree of balance by an existing calculation formula based on these degrees of liking, and adds the degree of balance to the topic list. The final topic list is transmitted to the GUI display unit, and a topic map is displayed on the display device.
The device of the present invention performs presentation of topics for specified persons, but in the flow chart below, for the sake of convenience, a method of presenting a topic for a person related to a user will be described with reference to the drawing.
Also, the related person may be acquired as known static information from a family relationship, a circle of friends, or work-related people. In the following, the related person may alternatively be referred to as the other person.
A technique of conducting a research on the human relationships, in various embodiments, will be described with reference to
Next, a technique of conducting research on human relationships over a wide range is depicted, as a method called snowball sampling. An example of the snowball sampling is illustrated in
In the example in
Next, in step 104, the method of the invention acquires a topic from the comments of the user and a related person. Here, the topic is acquired from the subjects, verbs, objects, nouns, gerunds, and the like present in the texts of conversation with the other person. In embodiments, the method of the invention performs natural language analysis and speech parts analysis on the texts of conversation to acquire the topic, or more simply, by acquiring all the words obtained by morphological analysis as topics. It should be noted here that a person may also be a topic.
Next, the method of the invention calculates the degree of balance of a topic with the related person in step 106. This step is the central step of the method of the present invention. Broadly speaking, the degree of the user's liking to the other person, the degree of the user's liking to a topic, and the degree of the other person's liking to the topic are calculated.
There are many existing techniques for calculating, based on a given text, the degree of liking indicating who likes what. The simplest method is to determine based on whether a predetermined word appears in a text. For example, if keywords that are registered in a dictionary in advance, such as “fun”, “exciting”, “like”, and “interested”, are present in a text, the subject has a liking for the object.
On the other hand, in the case of a negative keyword, the degree of liking is negative. The degree of liking is finely adjusted according to the number of appearances, the degree of emphasis and the like of the keyword. More specifically, the degree of liking may be precisely calculated by parsing the entire text. There are various other methods of calculating the degree of liking.
Normally, the “degree of the user's liking to the other person”, the “degree of the user's liking to a topic”, and the “degree of the other person's liking to the topic” are calculated from a plurality of sentences (texts), but a plurality of degrees of liking may sometimes be calculated from one sentence.
Then, in step 108, the method of the invention presents a topic that would be successful with the other person to the user based on each degree of balance. Preferably, the degree of balance is calculated by using Heider's balance theory. Heider's balance theory is described below with reference to
Simply put, the balance theory is a theory for measuring the psychological balance based on the difference in the liking from another person. In
According to this balance theory, one's liking to another person, one's liking to a certain object, and the other person's liking to the object are expressed by (+) and (−) and are multiplied together, and if balance is achieved, (+) is obtained, and if balance is not achieved, (−) is obtained. The bottom left example in
In this manner, the balance theory analyses the psychological balance between oneself and another person by analyzing what impressions are had in the relationship of oneself, another person (or the other person), and an object (or a topic).
The calculation formula for the degree of balance according to the present invention is given below as Equation 1. When the “degree of a user's liking to the other person” is given as A, the “degree of the user's liking to a topic” is given as B, and the “degree of other person's liking to the topic” is given as C, the simplest calculation formula for determining the degree of whole balance (V) is as follows. It should be noted that A, B, and C are rational numbers having signs, and thus V is also a rational number having a sign.
V=A×B×C Equation 1
Or, in the case of comparing the degree of balance with another system, normalization is needed, and a cubic root of V given above may be calculated and be taken as the degree of balance.
Another calculation formula for the degree of balance is given below as Equation 2. When, as in the case described above, the “degree of a user's liking to the other person” is given as A, the “degree of the user's liking to a topic” is given as B, and the “degree of the other person's liking to the topic” is given as C, the degree of balance V of an average value is determined by the following formula.
V=S×((|A|+|B|+|C|)÷3) Equation 2
The S here is for calculating the sign and is the sign for A×B×C, and takes the value of +1 or −1. Also, in the case where there is the degree of liking that takes the value of 0, this value is not used in the sign calculation.
V=−1×((100+10−20)/3)=−30 Equation 2 Example
Then, in step 108, the degree of balance with a related person for a topic is calculated, and is presented to the user. It is possible to have a topic with a higher degree of balance presented to the user as a topic that would be successful with the other person.
Now, when the user A is selected by a pointer 220, persons connected to the user A are displayed on the display device 22 as a list, as illustrated in
It is indicated by 310 in

Many example applications are conceivable with respect to the present invention without departing from its essence. For example, a real-time topic map may be provided by dynamically acquiring conversation data over the network from the communication interface 1707. Also, since the human relationships are updated in real time, dynamic discovery of a new related person is enabled.
Moreover, the present invention describes the method of calculating the degree of balance of a topic and one-on-one human relationships, and presentation thereof, but the degree of balance may also be calculated for a group. For example, an active group in a society is called a MOB, and application to calculation of the degree of balance for the MOB and a topic is also possible.
Additionally, the present invention is not limited to the embodiment described above, and various changes, modifications, and the like are possible within the scope of the present invention.
