{"title":"AUTOMATIC TEXT TRANSLATION SYSTEM FOR ARTIFICIAL LLANGUAGES","authors":"Olesia Barkovska, Anton Havrashenko, Vladyslav Kholiev, Olena Sevostianova","doi":"10.31891/csit-2021-5-3","DOIUrl":"https://doi.org/10.31891/csit-2021-5-3","url":null,"abstract":"The growing number and variety of artificial languages leads to the need and relevance of creating automatic dictionaries for their translation in order to facilitate human communication. Such languages include languages where vocabulary, phonetics, and grammar have been specifically designed to achieve specific goals and to communicate with a group of people by interests or place of residence. These languages can be distributed among people of certain professions or among neighboring nations. Examples are slang and surzhik. The common for them is that there is a basic language (literary), the intersection in spelling and meaning of words and phrases with which is quite large. The main goal of the project is to create a system of automatic translation of words and texts from / into arbitrary languages, including hybrid, artificial and slang ones. The proposed model shows the interaction and partial interdependence of the creation and adjustment modules and the translation module of the dictionary, which is explained by tacking the approach of reverse propagation of the translation error. To perform experiments and analyze the performance of the proposed approach to the organization of automatic translation of texts from and into arbitrary language, a software application was developed, which includes a subprogram of initial word processing for dictionary organization, one for creating a working dictionary and one for two-way improvement of created dictionary by the inclusion of new texts in order to improve the quality of translation, including the search for word phrases, idiom, and translation for them, the subprogram of dividing the dictionary into sub-dictionaries with a small percentage of text, the subprogram of the translator itself. To test and analyze the results of the proposed generalized model, three types of source texts were used:  literary poetry translation,  literary prose translation, literal prose translation. The results of the experiments showed that the proposed approach provides a high level of translation (up to 98,8%) in similar languages (between such languages as Ukrainian-Russian, or Ukrainian - Ukrainian-Russian surzhik wih equal word order in the sentence), especially with a literally translated source text. It has become known that the use of artistic texts to generate dictionaries is possible, but not very effective.","PeriodicalId":353631,"journal":{"name":"Computer systems and information technologies","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134162723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Was considered the decision-making model in uncertain conditions, based on the game theory concept when the uncertain situation was caused by objective circumstances which are unknown or have casual nature. Was formalized the optimal decision-making process on the conditions for adjusting the inventories use volume. Were considered the concepts and components of the information situation. Was considered the information situation classifier related to environmental uncertainty and applicable classical criteria in the decision-making process. The risk function in the implementation of a particular strategy is defined. Found risk magnitude for a possible information situation and the recorded state of the environment. Defined risk as the difference between the solution when accurate data on the environment state is available and the result when data on the state of the environment is not determined. Three-month plan creation for inventory use is taken as an example, were considered alternative strategies for the formation of inventories. Developed plan adjustment algorithm for enterprise production stocks. Defined an effective production strategy for the next strategic management of enterprise production stocks period according to the algorithm. An assessment matrix of the considered information situation is formed. According to estimates, an alternative solution was chosen. Using the voting method, the optimal strategy and the amount of risk were found. It is concluded that it is insufficient to use one classical criterion for optimal decision-making in uncertain conditions.","PeriodicalId":353631,"journal":{"name":"Computer systems and information technologies","volume":"7 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128729165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Машинне навчання та SEO-технології на даний момент є надзвичайно важливими в контексті розроблення ІС опрацювання та аналізу великих даних . Практично кожна популярна серед великої кількості людей ІС використовує відповідні механізми соціалізації.  Головною функцією ІС соціалізації особистостей за спільними інтересами є пошук релевантних користувачів, тому основним завданням є написати оптимізований алгоритм, який максимально автоматизує процес соціалізації користувачів. В даному випадку створений спеціальний алгоритм на основі таких алгоритмів, як алгоритм Левенштейна, розширення вибірки, N-грам та моделі Noisy Channel. До наукової новизни одержаних результатів варто віднести розроблення нового алгоритму аналізу користувацької інформації та пошуку найбільш релевантних користувачів ІС відповідно до проаналізованого тексту повідомлень профілю на основі вже існуючих алгоритмів Левенштейна, розширення вибірки, N-грам та моделі Noisy Channel.

Удосконалено згорткову нейронну мережу, що дозволило ефективно здійснювати пошук людських обличь на фото та перевіряти наявність вже існуючих людей в БД ІС. Система дозволить ефективно та швидко здійснювати підбір, аналіз, опрацювання текстових даних та формування кінцевого результату. В системі використовуються SEO-технології для ефективного та якісного інтелектуального пошуку та опрацювання відповідних даних за потребою конкретного користувача.
