Abstract: A method for document extraction includes receiving, from a user device associated with a user, an annotated document that includes one or more fields. Each respective field of the one or more fields of the annotated document is labeled by a respective annotation. The method includes clustering, using a template matching algorithm, the annotated document into a cluster and inducing, using the annotated document, a document template for the cluster. The method includes receiving, from the user device, an unannotated document including the one or more fields. The method includes clustering, using the template matching algorithm, the unannotated document into the cluster and, in response to clustering the unannotated document into the cluster, extracting, using the document template, the one or more fields.

Abstract: A multilingual translation device and method. The multilingual translation device may obtain a multilingual sentence, obtain vector values corresponding to words included in the multilingual sentence by using a multilingual translation model, convert the obtained vector values into vector values corresponding to a target language, and obtain a sentence in the target language, based on the vector values corresponding to the target language.

Abstract: A method and a device for converting a dialect of a predetermined language into a standard language include obtaining a sentence including a dialect word, identifying at least one common word that is used identically in the dialect and the standard language in the sentence including the dialect word, replacing the identified at least one common word with a predetermined keyword, obtaining one or more vector values corresponding to the predetermined keyword and each of remaining words included in the sentence, and obtaining a standard language sentence based on an arrangement of the obtained one or more vector values.
