A summary generating apparatus includes a text storage device storing text with information indicating a portion to be focused on; word vector converters vectorizing each word of the text and adding an element indicating whether the word is focused on or not to the vector and thereby converting the text to a word vector sequence; an LSTM implemented by a neural network performing sequence-to-sequence type conversion, pre-trained by machine learning to output, in response to each of the word vectors of the word vector sequence input in a prescribed order, a summary of the text consisting of the words represented by the word sequence; and input units inputting each of the word vectors of the word vector sequence in the prescribed order to the neural network.

A credibility determining system enabling highly accurate credibility determination of given information includes causal relation knowledge DBand search scope constraint DB. Causal relation knowledge each includes a combination of cause and result parts, and time and position constraints associated with the causal relation. The credibility determining system further includes a query generating unitretrieving a causal relation matching the input information and based on the time and position constraints stored in search scope constraint DBin association with the retrieved causal relation, generating a query for retrieving remarks from mini-blog text DB, a text search unitsearching for related remarks from mini-blog text DBusing the query, and a display candidate selecting unitclassifying the searched remarks to expressions interpreted as causes or to results, determining credibility of the input information based on the classification result and outputting the determination result.

System and method for determining credibility of information based on many remarks on a network, and non-transitory computer readable storage medium having stored thereon computer program therefor
