Entity Extraction:

 

Using the Text mining extension and coupled process documents operators, we can build a process for entity extraction.

 

Requirements:

  • Text Processing Extension
  • Text file of entities to be extracted
  • Text file to extract

For the entity file, a simple CSV where each line is an individual entity

 

Step 1:

Read CSV - Call our entity CSV file

Process documents from data - send the read CSV into the process documents

Inside the process documents from data we will need a filter tokens and a transform cases (lowercase)

 

Step 2: 

 

Using the word list output from step one, we connect it to a Process Documents operator to extract the word list from the text.
