how will you evaluate a text summarizer system?
user
the evaluation of a text summarizer system is typically performed by comparing its generated summaries against reference summaries. such a comparison is typically done using metrics such as rouge, which measures the extent to which the generated summary overlaps with a reference summary. other metrics such as semantic similarity metrics and human evaluation can also be used to evaluate a text summarizer system.
