Description

How to create subtitles based on your vocabulary level {METHOD FOR PRODUCING SUBTITLES ACCORDING TO VOCABULARY LEVEL OF USER}

The present invention relates to a subtitle generation method, and more particularly, to a subtitle generation method for retrieving a meaning of a vocabulary included in a source subtitle from a dictionary database and generating a lexical subtitle based on the retrieved meaning.

There is an increasing number of people watching content such as foreign films, dramas and news in order to improve their ability to listen to foreign languages. This is because it is easy to access foreign languages that can be difficult by watching interesting contents, and also because it adds the element of fun in foreign language learning, it is not easy to get tired. In particular, the foreign language learning method through the content is more preferred because it is a very useful learning method for acquiring vocabulary indicating topicality.

However, there are some problems in the foreign language learning method through such contents.

When the foreign language level of the content is much higher than the foreign language level of the user, the user does not hear a difficult vocabulary, so that listening is difficult, and eventually, interest may be lost.

An alternative is to use listening to help with listening. Here, the subtitle may be a subtitle translated from a foreign language into a native language, or may be a native subtitle (translated from a foreign language as it is) without a translation process. However, alternatives to using subtitles are not only helpful for improving listening skills because they are only urgent for reading subtitles.

An object of the present invention is to provide a subtitle generation method for retrieving the meaning of a vocabulary included in a original subtitle from a dictionary database and generating a vocabulary subtitle based on the retrieved meaning.

Subtitle generation method according to the present invention comprises the steps of: (a) obtaining a native subtitle; (b) extracting a vocabulary included in the original subtitle; (c) searching for a meaning of the vocabulary extracted in step (b) in a dictionary database according to a vocabulary level selected by a user among a plurality of vocabulary levels; And (d) generating a lexical subtitle based on the meaning retrieved in step (c).

The caption generating method according to the present invention may further include (e) displaying the lexical caption generated in the step (d).

The subtitle generating method according to the present invention further includes generating the dictionary database according to the plurality of lexical levels before performing step (a).

The plurality of vocabulary levels may be determined according to any one of a frequency of use of the vocabulary, a difficulty level, an age of a user, and a combination thereof.

Step (a) may include downloading the original subtitles through a network; And extracting the native subtitle from the video file.

In the step (c), it is preferable to search for the meaning in the dictionary database related to the lexical level above the lexical level selected by the user among the plurality of lexical levels.

The original subtitle and the lexical subtitle preferably include the same synchronization time.

The subtitle generation method according to the present invention has the following effects.

Unlike conventional subtitle display methods that display all contents, lexical subtitles are displayed according to the user's foreign language level, so that the user does not have any side effects that only follow the subtitles but also relies on listening to improve listening skills. have.

In addition, since the lexical subtitles according to the present invention include the same synchronization time as the original subtitles synchronized with the audio of the content, the user can view the lexical subtitles at a similar time when the audio of the content (eg, the dialogue of the drama) is heard. Therefore, the user can listen and learn vocabulary and meaning that the user does not know at the same time through the vocabulary subtitles.

In addition, the dictionary database is configured according to a plurality of vocabulary levels determined according to any one of the frequency of use of the vocabulary, the difficulty of the user, and a combination thereof, so that the user can conveniently select the vocabulary level according to his / her foreign language level. By selecting the lexical level, easy words that the user knows are not displayed as subtitles, and difficult words that the user does not know are displayed through lexical subtitles, thereby helping the user to learn vocabulary.

1 is a flowchart illustrating a method of generating a caption according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, 'original language' refers to a language of audio included in content. 'Vocabulary' refers to words, idioms, etc. included in the original subtitles. In addition, the term "lexical caption" refers to a caption displaying the meaning of the vocabulary included in the original caption.

1 is a flowchart illustrating a subtitle generation method according to the present invention.

Referring to FIG. 1, a dictionary database according to a plurality of vocabulary levels is generated (S100).

Here, the plurality of vocabulary levels is determined according to any one of the frequency of use of the vocabulary, the difficulty, the age of the user, and a combination thereof.

For example, a plurality of vocabulary levels are classified into four vocabulary levels by varying the number of stars such as '☆☆☆', '★ ☆☆', '★★ ☆', and '★★★' according to the frequency of use. Can be. In addition, the plurality of vocabulary levels may be classified into three vocabulary levels, such as 'beginner', 'intermediate' and 'advanced', depending on the difficulty level. In addition, the plurality of vocabulary levels may be classified into six vocabulary levels such as 'kindergarten student', 'elementary school student', 'junior high school student', 'high school student', 'college student' and 'public person' according to the user's age. In addition, the plurality of vocabulary levels may be determined as first to N-th (N is a natural number) vocabulary levels in consideration of frequency of use, difficulty, and age of the user.

The dictionary database stores the meaning of the original vocabulary (words and idioms) in its own language. The original language may vary according to the content to be played, and the national language may vary according to the user. For example, when a Korean user watches an American drama, the dictionary database stores the meaning of the English vocabulary in Korean. In addition, when a German user watches Japanese movies, the dictionary database stores the meaning of the German vocabulary in Japanese. Therefore, according to the user and the content viewed by the user, the dictionary database may provide the user with the meaning of the original vocabulary in the native language.

Each vocabulary level in the dictionary database contains a plurality of vocabulary suitable for the characteristic. For example, if the native language is English and the native language is Korean, the preschool vocabulary level may include easy vocabulary that preschoolers can learn, such as apple: apple, sky: sky, and car: car. Can be. Conversely, rather difficult vocabulary such as 'neutrality', 'isotope: isotope' and 'lawsuit: lawsuit' can be included in the vocabulary level above the 'high school' vocabulary level.

Next, a native subtitle is obtained (S110).

Specifically, original subtitles can be downloaded via a network or extracted from a video file.

Native subtitles can be divided into two types, one for subtitle files (for example, subtitle files with extensions of .smi, .srt, .rt, .sst, .sub, etc.) and videos. If there is a text stream multiplexed together (e.g. closed captioning).

If a subtitle file exists separately, the original subtitle can be obtained by downloading through a network, and in the case of a text stream multiplexed together in the video, the original subtitle can be obtained by extracting from the video file.

Next, the vocabulary included in the original subtitle is extracted (S120).

For example, if the original subtitle is "Uh, the way you crushed Mike at ping pong was such a turn-on.", The phrases such as way, you, crushed, ping pong, such, turn-on Can be extracted.

Next, the meaning of the extracted vocabulary is searched in the dictionary database according to the vocabulary level selected by the user among the plurality of vocabulary levels (S130).

Specifically, a meaning is searched for in a dictionary database associated with a lexical level equal to or higher than a lexical level selected by a user among a plurality of lexical levels.

For example, if the user is a high school student (or at a foreign language level of the high school student level), the user may select a 'high school student' vocabulary level. The 'high school student' vocabulary level includes a vocabulary that is difficult for a user having a foreign language level of high school students. Therefore, when the user selects the 'high school student' vocabulary level, the meaning of the vocabulary is searched in a dictionary database related to the 'high school student,' college student 'and' public person 'vocabulary levels that are higher than the' high school student 'vocabulary level.

As a result, all of the vocabulary included in the vocabulary level above the 'high school student' vocabulary level selected by the user is displayed on the screen on which the vocabulary subtitle is output, and the vocabulary included in the vocabulary level less than the 'high school student' vocabulary level is not displayed.

More specifically with the previous examples, the extracted vocabulary, way, you, crushed, ping pong, such, turn-on, is searched in a dictionary database related to the 'high school', 'college student' and 'public' vocabulary levels. . Then, only the meanings of the crushed and turn-on included in the vocabulary level above the 'high school student' vocabulary level are searched.

Next, a lexical subtitle is generated based on the retrieved meaning (S140).

For example, if the meaning of 'crushed' is 'win,' and the meaning of 'turn-on' is '(slang)', the vocabulary subtitle is 'crush: win, turn-on' Vocabulary subtitles that contain both vocabulary and meaning.

Preferably, the original and lexical subtitles contain the same synchronization time.

For example, for an SMI subtitle file, if the synchronization time of the original subtitle "Uh, the way you crushed Mike at ping pong was such a turn-on." Is <SYNC Start = 5997>, then the lexical subtitle "crush: wins" , turn-on: (slang) ((person)) excite "" also has a synchronization time of <SYNC Start = 5997>.

Next, the generated vocabulary caption is displayed (S150).

Vocabulary captions can be displayed on the screen of multimedia playback devices such as TVs, monitors, PDAs, and mobile phones. As described above, by displaying the synchronizing time of the original subtitles and the synchronizing time of the vocabulary subtitles in the same manner, the user can view the vocabulary subtitles at a similar time when the audio of the content (eg, the dialogue of the drama) is heard. As a result, the user can listen and learn vocabulary and meaning that the user does not know through the vocabulary subtitles.

Although the configuration of the present invention has been described in detail, these are merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. This will be possible.

Therefore, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments. It is intended that the scope of the invention be interpreted by the following claims, and that all descriptions within the scope equivalent thereto shall be construed as being included in the scope of the present invention.
