Description

A method for automatic generation of a proposal word in a Korean input method that follows the Roman numeral notation.

The present invention relates to a character input software, and more particularly, to a method for generating a predicted input word (proposal word / predictive word) and a method for improving the accuracy of an additional predicted word list when a character is input through romanization based on the Roman- And a method for improving the convenience of the Hangul input system.

(Hereinafter referred to as "device") including a smart phone, a tablet, a PDA (Personal Digital Assistant), a wearable (wearable) computer in the form of a watch, (Input method) is installed so that one kind of device can input and display at least one language according to the tendency of production cost reduction and international standardization in recent years. And one or more character language inputs are routinely performed in the device. Also, the age of globalization has come, in which the people who use and input a specific language are not limited to one nation but to other people in different regions for personal or business purposes.

As a method of using and inputting a specific language in common among different ethnic groups, there is a method of fully acquiring the language and acquiring and utilizing the same language input method and usage style as that of the mainland person. However, Due to the differentiation of original classification and structural classification, there are many restrictions to acquire and use several languages at the same time for a given time. Especially at the level of the general public, not professional translation or interpreters.

When the language is widely used in other nations and countries, it facilitates cultural exchanges and information acquisition and exchanges, which is also helpful for national strength. In the current era, languages used mainly by countries or ethnic groups are more easily accessible The method of inputting the language by phonetic symbols, that is, the method of inputting and using the Roman numeral notation, is widely used. For example, in the case of Chinese, there is a Chinese standard input method Pinyin input method in which pronunciation is converted into a pinyin letter by inputting a romanized letter, which is a romanization word closest to the Chinese pronunciation in order to input a "good" Hao '(Hao) is input. Another similar example is the input method of Romaji in Japanese, and the method of inputting 'ii' to input the hiragana letter 'い い' which means 'good'.

It is also important to increase the number of foreigners who can speak Korean through the globalization of Hangul at the present time of the increase in the number of foreigners who want to learn Korean language materials and sales of Korean textbooks. In this background, there is no input method for foreigners for international activation of Hangul, and phonetic symbol input method that foreigners can easily touch when they think of Hangul. In order to utilize Korean language as a central mediator of Korean cultural communication through the globalization of Korean language and to enhance the national power, it is necessary to disseminate improved roman-based Hangul pronunciation symbol input method for foreigners.

The present invention discloses a method for reducing entry barriers to the use of Hangul by using an improved Romanization-based Hangul pronunciation symbol input method using a proposal language generation technique and an accuracy improvement technique so that Hangul can be widely used from users of other language cultures. It is another object of the present invention to provide a method for providing an improved romanization-based Hangul pronunciation symbol input method while making full use of the prior art, and at the same time contributing to globalization of Hangul and increasing exchange with other language cultures through Hangul.

Latin also includes French as well as English. Roman is not a language, Roman is not a synonym for English.

In the following description, "English" is one of the languages that use 'roman' as a language. It is a language belonging to the Germanic language group of German / Indo-Germanic german. It is used in many countries including USA, UK, Canada, Australia, It has an excuse for using an international language. The relationship between roman and English is the same as the relationship between Korean and Korean. For example, Hangul can be a means of expressing the language of the Korean language, the North Korean language, and the Chiachi language, the Chiachi language.

In the following description, "Hangul" is a unique character, a phonetic character created in the name of Hunminjeongum in the Joseon Dynasty and used until now, and is a character different in composition principle and shape from the roman. Hangul is not synonymous with Korean. Hangul means the character itself, which is a means of expression composed of Hangul consonants and vowels used in Korean Korean, North Korean, and Chiacchi.

It is a rule to express a syllable or a word of a language with only a romanization by associating at least one Roman character bundle with a phonetic symbol. For example, in the case of the Republic of Korea, the "Korean Romanization notation" for Korean is fears / noticed and used as a standard and defined as a standard. The Romanization notation for the Korean language used in North Korea is based on the Romanization notation, For the Chia Chia language, it can be a 'Chiachi language' written in Romanization of the Chia Chia language. (Currently, Hangul is not an official language of Chiacia.)

FIG. 1D is a configuration diagram showing a case where the components of the input method according to the present invention are combined.

Referring to FIG. 1D, in order to efficiently use processing resources of a device, some functional elements included in two different embodiments, which are different from other embodiments of the present invention, are integrally provided.

The process of the input method according to the invention

FIG. 2A is a detailed flowchart illustrating a process of converting an input of a Roman character string 'nado', which is a target character string, into a set of Korean character strings, by driving an input method 110 according to an embodiment of the present invention.

Referring to FIG. 2A, the process starts with a step 201 of detecting romanization by a user operation. The inputted roman alphabet sequentially performs the notation analysis and conversion step 202 according to a predetermined Romanization notation rule preliminarily designated by the notation combination unit 111 of FIG. 1A. The predetermined Romanization notation rule is composed of phoneme-by-phoneme conversion rules. In the following description, it is assumed that the Korean Romanization notation, which was announced by the Ministry of Culture and Tourism on July 7, 2000 (Notice No. 2000-8), is used as the conversion rule. For example, if the user inputs 'n', the Romanization input sensing step 201 is performed, and the notation combining unit 111 of FIG. 1A performs a notation analysis and conversion step 202, . If the implementation is not equipped with the minimal requirements of the complete Hangul characters, such as initiality and neutrality, the result of the conversion may not be obtained for the words. The main purpose of the input method is to communicate through the display of the completed Hangul And will be described in the following other embodiments. The list generator 115 of FIG. 1A generates and manages the converted Hangul characters into a single list updated through a result cataloging step 207. The notation combining unit 111 may determine (208) whether the inputted roman characters or characters can be converted into another Hangul characters in addition to the converted characters to perform analysis and conversion with another Hangul characters that can be converted. In the current input example, there is no number of cases that can be processed any more, so the notation analysis and conversion step 202 is not repeated. Since there are no further convertible combinations, a list including the result 'n' by the romanization input 'n' can be selected by the interactive method such that the user can select in the result list output step 209, Display in space. If the displayed result 'b' is an input result desired by the user, the selection of the word is instructed to the input method 110 by selecting the item, and the selected word is transmitted to the destination software through the list selection detection step 210 ) To complete the input operation. In addition to the selection action of the list, the user can additionally perform other editing operations by continuously inputting a romanization or by performing a backspace operation.

If the user inputs 'a' again based on the above example 'n' input, the romanization input 201 is driven again and the inputted romanization string is accumulated as 'na' (111) converts into the Hangul character 'I' in the notation analysis and conversion step (202). The list generator 115 of FIG. 1A generates and manages the converted Hangul characters into a single list updated through a result cataloging step 207. The notation combining unit 111 may determine (208) whether the inputted roman characters or characters can be converted into another Hangul characters in addition to the converted characters to perform analysis and conversion with another Hangul characters that can be converted. In case of present input string 'na', only 'a' corresponding to 'n' corresponding to consonant 'ㄴ' and 'a' corresponding to vowel 'a' can be combined with one word and there are no other convertible characters Do not. Then, when the user sequentially inputs 'd' and 'o', the notation combination unit 111 of FIG. 1A repeatedly performs the Romanization input sensing step 201 and the notation analysis and conversion step 202. It creates a list of converted strings called 'me' (meaning myself, including myself). The rules are repeatedly applied to generate a Hangul character or a string of all other possible combinations of transforms to separate them into 'nad' and 'o', and the 'grainy' converted to 'grainy' and ' And adds it to the character string list through the result cataloging step 207 of the list generating unit 115. The iterative conversion to generate a Hangul character or a string of all other combinations that can be transformed at the core stage of the present circle can be performed by, for example, determining the starting position of the judgment based on the length of the inputted Roman character or string If the target string 'nado' having a string length of 4 is input, the length read from the start position of the first character is incremented by 1, and the determination and combination . The first character recognizes the letter 'n' of length 1 as the first letter 'c', recognizes the letter 'a' as continuous length 1 thereafter as neutral, and 'd' and 'o' Are also repeatedly perceived as primitive and neutral. When the recognition is completed, the character 'n' of the length 1 of the first position is recognized as a leading character 'b' and the character 'a' of the subsequent length 1 is recognized as neutral , The third character 'd' after that is regarded as a vowel, and the final character 'o' is a vowel after completing the word 'grainy', so it is judged that 'o' It is possible to apply a combination of characters and different algorithms can be used depending on the implementation. In accordance with the romanization rules, there is no further convertible combination other than the result of the above embodiment. Therefore, the input method 110 outputs a result list including 'nado' and 'kana' generated by the consecutive romanization input 'nado' And outputs it to the designated space through the step 'result list output step 209'. If there is a desired result among the outputted words, the user selects a word in the input method 110 through an operation of selecting one item, and the input method 110 instructs the user to select a word, The word is transferred to the destination software (211) to complete the input operation.

FIG. 2B is a detailed flowchart illustrating a process of generating and transmitting a romanized Korean character or a set of character strings by operating an input method 110 according to another embodiment of the present invention.

Referring to FIG. 2B, most of the whole process is similar to the embodiment of FIG. 2A, except that the process further includes processes 203 and 204 related to two validity filtering words that are meaningless. In the following other embodiments, differences from the first embodiment will be mainly described. In another embodiment, as in the above embodiment, the process starts with a step 201 of detecting romanization input by a user operation. The input roman characters sequentially perform the notation analysis and conversion step 202 according to the Romanization notation rule preliminarily designated by the notation combination unit 111 of FIG. 1B. For example, if the user inputs 'n', the Romanization input sensing step 201 is activated, and the notation combination unit 111 of FIG. 1B receives the character corresponding to 'b' through the notation analysis and conversion step 202 . Hereinafter, this embodiment is the same as the embodiment. However, in another embodiment of the present invention, the validity verification unit 112 of FIG. 1B is provided, and when the character converted to 'B' is displayed to the user, A validation step 203 and a decision step 204 for verifying the document with minimal resources using only its own rules without additional data such as an external language dictionary. The validity related step is valid when the user inputs a romanization string. For example, if the user can input 'annyeong' (hi) to create a combination of Korean characters using the notation analysis and conversion step 202, , 'Angeon', 'angeon a' and so on. As the length of the input romanization string becomes longer, it can accumulate meaningless or insignificant combinations of words. Even if you enter a word of three or four words in Hangul syllables, a large number of unnecessary words can be generated. The purpose is to filter words only. In the case of the above example 'annyeong', unnecessary words among the generated four Hangul words are often included as a syllable, so that the notation combination unit 111 of FIG. 1B normalizes it, Or the string is included as a syllable in a syllable, a notation analysis and conversion step 202 determines that the string is not valid. Thus, only 'hi' and 'no' 115 to the cataloging step 207 to generate a list of results. The validity determination rules of the validity-related steps 203 and 204 of the validity verification unit 112 of FIG. 1B may be modified according to needs and objectives, or may be configured by applying an externally adjustable factor (environment setting / option) or artificial intelligence logic And the like. After the result cataloging step 207, the configuration and processing are performed in the same manner as in the above embodiment.

FIG. 2C is a detailed flowchart illustrating a process of generating and transmitting a romanized Korean character or a set of character strings by operating an input method 110 according to another embodiment of the present invention.

Referring to FIG. 2C, most of the whole process has almost the same configuration as the other embodiment of FIG. 2B. In contrast to the other embodiments, the validation portion is replaced with a dictionary comparison unit 113 that utilizes a language dictionary, and additionally, a storage 103 is required. In still another embodiment, differences from the above-described other embodiments will be mainly described. In another embodiment, starting from the step 201 of sensing the romanization input by the user operation as in the above embodiment and the other embodiment, the notation analysis and conversion 202 (not shown) by the notation combination unit 111 of FIG. ). The above is the same as the other embodiments and one embodiment. However, the present embodiment is different from the above embodiment in that the dictionary comparison unit 113 of FIG. 1C is provided and the characters converted from the Roman characters input from the user are meaningful contents or characters And verifies whether it is valid through the language dictionary 120 of Fig. 1 (c), to provide a meaningful result to the user. The dictionary comparison is effective when the romanization string input of the user is long as in the case of the validity related steps in the other embodiments. In the notation analysis and conversion step 202, " annyeong " A conversion result set such as 'Ahnjae a', 'Anjeon', and 'Angeon a' can be generated. This result is driven by the language dictionary 120 installed in the storage unit 103 under the control of the input method 110 to carry out the comparison step and collects only the results determined to be valid in the comparison. The language dictionary 120 may be a standard Korean dictionary as a kind of database, and may be a terminology dictionary, a colloquial dictionary, or a word database in a dictionary form of a specialized purpose according to an implementation. The comparison between the converted character or string and the character or string in the language dictionary can be modified according to the implementation method and purpose, such as a method in which each configured character is completely matched or a method of matching the first half, or an externally adjustable parameter (configuration / option) Or to apply artificial intelligence logic. For example, it is assumed that the purpose and use destination of the input method 100 according to the present invention is a general dialogue and communication for a general public, and a built-in language dictionary is a standard Korean dictionary database in which a written language word is included, When searching and comparing with the linguistic dictionaries using the string matching method in the state where 'Hi', 'Annie a', 'Angeon', and 'Angeon a' are obtained as a result, only 'Hi' Is determined to be a valid normal word to be filtered. In the subsequent steps, the filtered final result 'goodness' is generated as a list through the result cataloging step 207 of the list generating unit 115 of FIG. 1C and outputted to the user 209), and a step 210 of sensing the user's selection is performed, and the selected word is transferred 211 to the destination software. In another embodiment of the present invention, when it is determined that the language dictionary is compared with the language dictionary and the dictionary dictionary is valid, the generated word is not generated and managed as a list by the user's input, . For example, if a set of words combined by the user's input roman includes "goodbye" and a single specific dictionary database containing colloquial vocabulary entries through the first half match method is searched and compared, &Quot; Hello " may be determined as a valid word. The first half match is a way to make a valid decision if the character or string to be compared is completely contained in the other half of the first half of the string, so that the comparison between 'Hi' and 'Hello' or 'I' It is a method of judging. Therefore, another embodiment of another form is a comparison method having an advantage that it is possible to easily provide a semantic word composed of a complete word for communication even if the whole word is unknown. In addition, a complex comparison method considering phonological changes, palatal changes, and proper nouns can be constructed and used according to the purpose and environment according to the implementation method. The word matching step through the dictionary comparison step 205 and the similar word existence determination step 206 by the dictionary comparison unit 113 of Fig. 1C of yet another different embodiment above is similar to the simple dictionary word It is also clearly distinguished from the proposal language providing technology of the list formula.

In addition, according to the implementation method, the notation analysis and transformation step 200 may be followed by concatenating both the validation components 203, 204 of FIG. 2B and the precomparison components 205, 206 of FIG. 2C An input method of the type shown in FIG. 1D may be configured to increase the dictionary comparison efficiency by using the validation step as a pre-processing step and the pre-comparing step as a post-processing step.

As described above, each embodiment can be selectively implemented according to the objective and the environmental conditions of the apparatus. One embodiment provides additional minimal convenience in a constrained minimum space device, while another embodiment provides additional minimal convenience in the absence of space; another alternative embodiment provides more accurate semantic-based results when there is room in storage space. It is more useful when providing.

The 'n' character is input by the user's operation to the input method 110 of FIGS. 1A, 1B, and 1C. The input method 110 performs the functions described in Figs. 2A, 2B, and 2C for a short period of time when the user operates a character, and displays the result in the proposal word display area 301. [ For example, when the user performs an input operation by pressing an area in which 'n' is drawn in the input method 110, the input method 110 of FIGS. 1A, 1B and 1C converts the input roman 'n' And the Romanization input sensing step 201 of FIG. 2C. The notation combination unit 111 of FIGS. 1A, 1B, and 1C then converts the input characters to 'C' through the notation analysis and conversion step 202 of FIGS. 2A, 2B, and 2C. Then, the input method 110 generates a list of characters '?' In the result cataloging step 207 of FIG. 2A through the list generating unit 115 of FIG. 1A, FIG. 1B and FIG. 1C After confirming and repeating the step 208 of checking whether there is an additional convertible word, a list of the result list is outputted to the user in the proposal word display area 301 (209). Referring to FIG. 3B, the internal process from inputting romanization to outputting result by user's operation is performed in real time. The user can immediately use the convenience function without further manipulation. In another embodiment, the transformed '?' Character is validated through the validity verification unit 112 of FIG. 1B and the validity verification step 203 and the determination step 204 of FIG. 2B are valid as characters. If the validity determination rule which treats a character consisting of only the primitive or neutral as invalid is embedded as in the example used in the first description of FIG. 2B, the validity verification unit 112 of FIG. The validation step 203 and the determination step 204 do not perform the result culling step 207 of FIG. 2B to filter out invalid characters. Therefore, no characters appear in the proposal word display area 301 of FIG. 3B. In the case of two different alternative embodiments, the translated " a " character is valid as a character through the dictionary comparison unit 112 of FIG. 1C, in the dictionary comparison step 205 and similar word determination step 206 ). When the comparison is made in accordance with the dictionary matching method in the same way as the example used in the first description of FIG. 2C, the '?' Character is selected according to the characteristics and purpose of the language dictionary 120 installed in the storage unit 103 of FIG. In the dictionary comparison step 205 and the similar word determination step 206 of FIG. 2C, if the character is filtered out as an invalid character, the result listing step 207 of FIG. 2C is not performed. No characters are also displayed in the area 301. In other words, a character appears in the proposal word display area 301 of FIG. 3B. That is, the final character of the Hangul character or character string is predicted from the Roman character currently input by the user according to the implementation method. If no character is displayed, The rule also means that the user's input is not valid enough to predict or generate the appropriate Hangul character or string. The validation step 203 and decision step 204 of FIG. 2B of another embodiment and the prior comparison step 205 and similar word determination step 206 of FIG. 2C of two different alternative embodiments are similar to those of FIG. If the input is continuous and long, a combination of various deformations with meaningless Hangeul characters can be generated, which is an important step for enhancing the convenience by preventing the user from crossing over. The input method 110 may pass the romanized input character inputted from the user through the character input area 300 as shown in FIG. 3B according to the implementation. Depending on the implementation method and purpose, the input roman characters themselves may not be transferred to the destination software, or they may not be displayed on the screen. Referring to FIG. 3C, a process of inputting the next roman by inputting the 'a' area 303 of the input method 110 is shown. Since the input of the user is 'na', the proposal word 'I' is updated to the input of the user in the proposal word display area 301 through the internal processing of the various steps described above. To input 'nado', the 'd' area 304 of FIG. 3D and the 'o' area 305 of FIG. 3E are sequentially inputted to sequentially display a proposal word of 'I' And shows the displayed state. The input method 110 includes a step of converting the Korean alphabet into Korean characters, a filtering step, a result listing step, and a list listing step, through each internal constituent part shown in FIGS. 1A, 1B and 1CD, Continue the display step again. And finally outputs a list of performance results of each turn to the proposal display area 301. [ Referring to FIG. 3F, there is shown a state in which the user performs a delivery operation to finally deliver 'I', which is a destination string output to the proposal word display area 301, to the destination software. The input method 110 recognizes the selected word through a step 211 of recognizing the selected word through the user list selection sensing step 210 of FIGS. 2A, 2B and 2C and transmitting it to the destination software / RTI > Referring to FIG. 3G, the selected character string 'I' is transmitted to the character input area 300 of the destination software through the step of transmitting the selected word in FIGS. 2A, 2B, and 2C to the destination software.

In the process of transition from the state of FIG. 3A to the state of FIG. 3G, particularly in the step of inputting romanized letters repeated as shown in FIG. 3A to FIG. 3B, although the compound operation is performed through various steps and functions internally, There is a convenience advantage that a complicated process is hidden. Technicians also have the advantage of time and development convenience in developing a user-centered technology that is sufficiently better based on conventional techniques without learning or finding new technologies in designing and implementing input methods.
