- locate and comprehend parts of text
- summarize useful information across documents
- converting them into a clean, structured representation
3 Goals of Information Extraction:
- Information Organisation - we can organise info where humans can understand
- Entity and Relationship Identification - identify r/s between entities through r/s with text
- Generation of Structured Data - put information contained within text into semantically precise form allowing for further algorithmic inferences
Entities are the units that get extracted, and they are found by Named Entity Recognition (NER).
