A method for training a language model for multimodal dialog includes generating a first token sequence by tokenizing one or more text messages included in multimodal dialog data, generating a second token sequence by inserting, based on an appearance position of an image included in the multimodal dialog data, one or more image presence tokens and one or more image non-presence tokens into the first token sequence, and replacing one or more tokens among a plurality of tokens generated by the tokenization with a mask token, generating one or more feature vectors for the image, and training an artificial neural network-based language model to predict, based on the second token sequence and the one or more feature vectors, an appearance position of the image in the multimodal dialog data.

The present disclosure relates to a document classification method and a document classification device. A document classification method performed by a processor inside a computing device according to an embodiment of the present disclosure may include: obtaining a predicted dimension which is a dimension of a feature vector necessary to classify a document image that has been input, through a learned dimension prediction model; generating a feature vector of the document image, through a feature extraction model based on the predicted dimension; and identifying a document type corresponding to the document image on the basis of the generated feature vector.

The present disclosure relates to a text-based document classification method and a document classification device. A text-based document classification method according to an embodiment of the present disclosure is performed by a processor inside a computing device, and may include: extracting, from a document image that has been input, words included in the document image; generating, based on a degree of similarity between the words, a word set including a configured number of words; generating a word set image by individually turning the word set into an image; extracting an important keyword used for document classification among words included in the word set image; and classifying a type of the document image by using the important keyword.
