Method for determining stock item index using media and System for carrying out the same}

The present invention relates to a method for selecting a theme based on media and obtaining an auxiliary indicator for investment through this, and a system for performing the same.

With the rapid development of various networks or the Internet in recent years, the types of media are diversified, and the types of information handled through the media are also diversifying. Accordingly, investment stocks that are sensitive to the media are increasing, and on the contrary, the good or bad news of investment stocks are often spread through the media.

In other words, it is not an exaggeration to say that recent investment stocks and media are closely related. Therefore, media-related information is likely to be used as a very important auxiliary indicator for successful investment item selection and purchase/sell timing decisions.

However, from an individual's point of view, it is difficult to collect as well as analyze a vast amount of media-related information, and the current investment subsidiary indicators do not sufficiently reflect media-related information.

However, the present invention may be implemented in various forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and similar reference numerals are assigned to similar parts throughout the specification.

Throughout the specification, when a part "includes" a certain component, it means that other components may be further included rather than excluding other components unless specifically stated to the contrary. In addition, parts denoted by the same reference numerals throughout the specification refer to the same components.

In one embodiment of the present invention, a theme is selected based on the frequency and importance of the exposed media, the selected theme is indexed to calculate a theme index, and the related investment item is selected based on the selected theme, and the calculated theme index It is proposed to calculate the impact of related stocks according to the related stocks as a related stock index and use it as an investment subsidiary indicator.

For example, media are video media such as over-the-air/cable TV based on radio waves or IP networks, audio broadcasts such as radio or cast content, Internet news media, Internet posts such as blogs, social network service (SNS) posts, Includes community posts, but is not necessarily limited thereto.

In addition, the investment item may include stocks, futures, virtual currency, spots, real estate, etc., but these are illustrative and are not necessarily limited thereto, and an investment object is sufficient.

First, a process of calculating a media related index according to an embodiment will be described with reference to FIG. 1.

1 is a flowchart showing an example of a process of calculating a media related index according to an embodiment of the present invention.

Referring to FIG. 1, in order to calculate a media related index according to the present embodiment, media collection may first be performed (S110). Here, for media collection, data crawling and indexing techniques widely used in search engines may be used, collection may be started based on real-time issue search words in one or more search engines, and one or more preset source addresses may be used. Combinations are also possible.

Here, the preset one or more source addresses may be homepages of broadcasters or internet news media, or addresses of blogs or SNS accounts of influential bloggers.

Of course, such a collection method is exemplary, and the present embodiment is not limited to any method as long as it is possible to collect media information.

Next, the theme classification process of the collected media information may be performed (S120).

Themes may be classified according to a plurality of preset categories such as general, season, environment, disease, and new technology, or may be newly created when media information that is not included in a preset category but correlated with each other is greater than a certain quantity.

For example, general themes may include bio, environmental industry, casino, shipbuilding, medical equipment, travel, semiconductors, construction, and games, which are constantly issues. In addition, elections (e.g., presidential elections, general elections, local elections, etc.) returning periodically for each season theme season, and sports seasons (Olympic Games, World Cup, professional baseball, Super Bowl, etc.) may belong to this. In addition, the environmental theme may include earthquakes, wind power, rainy seasons, droughts, and floods according to the natural environment. In addition, disease themes may include bird flu, foot and mouth disease, Zika virus, super bacteria, and killing mites. In addition, new technology themes may include newly developed drones, AI, big data, IoT, iris recognition, and new technologies such as autonomous driving.

Of course, the above-described theme classification criteria are exemplary, and it is obvious to those skilled in the art that different theme classifications are possible.

When theme classification for media information is performed, a theme index may be measured for each theme (S130).

The process of measuring the theme index may include 1) collecting and filtering metadata included in the media, 2) assigning points to data by applying weights for each media, and 3) converting the index data.

Here, the process of collecting metadata may mean a process of acquiring at least one of body text, images, videos, comments, views, hashtags, and preferences (likes, number of shares, number of recommendations, publishers, etc.).

In addition, in the filtering process, keywords are extracted from metadata, duplicate information is removed by determining whether there is overlap with previously collected data, and whether to reflect in the theme index using an algorithm that measures the positive/negative index for each keyword. It may include at least one of the process of determining. For example, a threshold value may be preset as a ratio value of a negative index to a positive index to determine whether to reflect the theme index (eg negative index / positive index <20%).

In addition, the weighting process may be a form in which different weights are assigned for each source of media. For example, a terrestrial/cable integrated channel may be assigned 8 to 13 points, a coverage channel may be given 5 to 10 points, an SNS 3 to 8 points, and a community 1 to 3 points may be given. Here, the score of the broadcast channel can reflect the viewer rating, and the number of followers, preference information of a specific post, and the number of re-shares (retweet, scrap, embedding, etc.) can be reflected in the SNS, and the community has the number of members and the degree of activation ( The number of posts by time unit, number of views), etc. may be reflected.

In addition, the index data conversion process refers to the process of applying the weighted score to the theme in a time unit (e.g., time zone, daily, weekly, etc.) (i.e., converting media information of the theme to which weights for each media source is applied to index data) Can be done, and maximum score limits can be set as needed.

Next, a related stock index may be measured (S140). This process may be performed in the form of setting investment item data related to the theme at regular intervals or at all times, and selecting and managing the automatically extracted related items. For example, in the process of measuring the theme index described above, the price flow of a related item for each theme to which a score equal to or greater than a preset reference value is assigned may be monitored for a certain period. Monitoring can be performed in the form of measuring the degree of impact by comparing the change in the theme index with the price of the related stock, and the result can be recorded as the related stock index.

When the theme index and the related stock index are calculated, the calculated information may be output in a predetermined format (S150). The form of the output may be a table, a graph, or a combination thereof, but is not limited thereto. A specific form of this output process will be described with reference to FIGS. 2 and 3.

2 shows an example of a form in which media related index information is output according to an embodiment of the present invention.

Referring to FIG. 2, as a specific theme (here "drone") is selected, the average theme index and related stock index of the items related to the theme may be output in a graph form by time. In FIG. 2, the time unit on the horizontal axis is displayed for each month, but it goes without saying that the time unit such as output by date or time of a specific day may be changed.

In addition, when a specific point 210 is selected on the graph, detailed information 220 of the corresponding point, for example, a score for each media as a basis for calculation, and a theme index value of the corresponding point may be additionally displayed.

3 shows another example of a form in which media related index information is output according to an embodiment of the present invention.

Referring to FIG. 3, as a specific theme (here "drone") is selected, a list of items 310 related to the theme is first provided, and when a specific stock 311 is selected from the list, the stock price of the stock changes. It can be displayed in the form of a graph for each time period together with the related theme index.

Therefore, through the output format as shown in FIG. 2, the user can easily see how much the media affects the price fluctuation of the related stock group for a specific theme, and the influence of individual stocks and themes through the output format shown in FIG. Can be easily seen.

Meanwhile, in the mechanical implementation, each process shown in FIG. 1 may be implemented as one software module or a hardware module, and depending on the implementation, one step may be implemented by two or more modules, and two or more steps may be implemented. It is obvious to those skilled in the art that it may be implemented as a single module.

For example, as shown in FIG. 4, the media-related index calculation device 400 according to the present embodiment includes a media collection unit 410 that collects media information, and a theme classification module 420 that classifies the collected media information by theme. , A theme index measurement module 430 that indexes data through keyword extraction, filtering, weighting, and scoring for each classified theme, and a related stock index measurement module that indexes the association between theme index and price fluctuations for each item related to each theme 440 and an output unit 450 that outputs the theme index and the related item index in a predetermined format. Here, the output unit 450 may be in the form of a communication module that outputs a digital signal corresponding to the theme index and the related event index to another device or a logical address according to a preset protocol, or may be a display device that outputs visual information. , Print media or sound output means may be used, but this is only illustrative and is not limited thereto.

In addition, the detailed operation process of the module/functional unit corresponds to each process described with reference to FIG. 1, and redundant descriptions are omitted.

The present invention described above can be implemented as a computer-readable code in a medium on which a program is recorded. The computer-readable medium includes all types of recording devices storing data that can be read by a computer system. Examples of computer-readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SDD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is this.

Therefore, the detailed description above should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
