Summarizer

Apply summarizer to an index

GUI

Navigate to Tools -> Summarizer and click on the CREATE button on top-left. Choose the name for your task (Description). Select appropriate indices and then fields that contain the textual data you want to summarize. Select summarization algorithm(s) you wish to use. Finally, specify the expected size of the summaries either as a ratio to the original length of the text or as the number of sentences.

Märkus

Ratio must be a decimal number between 0 and 1 and the number of sentences must be specified with a positive integer. The maximum number of sentences you can have is 100. It is recommended to use ratio if the index contains many documents with different lengths and you don’t know what would be optimal number of sentences. On the other hand, specify the length in the number of sentences if you need the ouput strictly to be a fixed number of sentences.

If the task is successful then a new field is added to indices which contains the summaries.
