    摘要： An apparatus for anomaly detection, the apparatus comprising means for:
    - Collecting a plurality of log messages from a data processing system, log messages comprising textual content and numeric attributes,
    - Classifying the plurality of log messages into a plurality of clusters as a function of a number of the numeric attributes in the log messages, such that the log messages within a cluster have a given number of the numeric attributes,
    - For at least one of the clusters, computing at least one encoding vector associated to a numeric attribute,
    - Computing a combined semantic embedding vector from the textual contents of the plurality of log messages,
    - Combining the at least one encoding vector with the combined semantic embedding vector into a final encoding vector, and
    - Feeding the final encoding vector to an anomaly detection module intended to detect an anomaly in the data processing system.
