  • Patent number: 11971918
    Abstract: A calculation unit (15a) calculates a degree of association between words included in compound word candidates that are each constituted by consecutive words in a document. The calculation unit (15a) calculates the degree of association by using a conditional probability that is a probability of a word that precedes a last word being present in the document under the condition that the last word follows. A selection unit (15b) selects, as a compound word, a compound word candidate whose degree of association thus calculated is higher than a predetermined threshold value. A learning unit (15c) learns a positional relationship between words that include the selected compound word in the document and predetermined tags added to the document. An addition unit (15d) adds the predetermined tags to the document based on the positional relationship between words that include the learned compound word in the document and the predetermined tags added to the document.

  • Patent number: 11943243
    Abstract: In an anomaly detection method that determines whether each frame in observation data constituted by a collection of frames sent and received over a communication network system is anomalous, a difference between a data distribution of a feature amount extracted from the frame in the observation data and a data distribution for a collection of frames sent and received over the communication network system, obtained at a different timing from the observation data, is calculated. A frame having a feature amount for which the difference is predetermined value or higher is determined to be an anomalous frame. An anomaly contribution level of feature amounts extracted from the frame determined to be an anomalous frame is calculated, and an anomalous payload part, which is at least one part of the payload corresponding to the feature amount for which the anomaly contribution level is at least the predetermined value, is output.
