1. An information providing system comprising:
a memory storing instructions; and
a processor configured to execute the instructions to:
acquire log data generated by an information equipment system;
calculate a first term frequency-inverse document frequency (TF-IDF) vector to extract a feature of the log data;
calculate a second TF-IDF vector as a feature of information included in history information related to the information equipment system;
acquire information from the history information based on a degree of similarity between the first TF-IDF vector and the second TF-IDF vector;
output the acquired information;
generate a model for calculating likelihood of classifying a log for each type of failure and for each time interval acquired by dividing a time until a failure occurs; and
detect a sign of failure occurrence of the information equipment system by using the model and the extracted feature of the log data.
