[Problem] To provide a technology for automatically detecting, with high precision, a specified description of interest within a text, and for automatically abstracting the text with a focus on the detected description. [Solution] Provided is an abstract generation device comprising: a text storage device for storing text together with information indicating sections of interest thereof; word vector conversion units 834 and 836 for vectorizing each word of the text, adding to the vectors elements indicating whether the words are the sections of interest, and converting the text to a word vector sequence; LSTMs composed of neural networks carrying out sequence-to-sequence conversions and pre-learned by machine learning to output, in response to each of the word vectors of the word vector sequence being inputted in a prescribed sequence, an abstract of the text composed of the words represented by the word vector sequence; and input units 838–848 for inputting into the neural networks in the prescribed sequence each of the word vectors of the word vector sequence.
