Study Notes
Text Mining vs Data Mining
- Text mining involves extracting useful information from unstructured textual data, whereas data mining involves extracting useful information from structured or semi-structured data sources.
- Text mining and data mining both involve preprocessing operations before extracting useful information.
Key Concepts in Text Mining
- Text mining involves identifying and exploring interesting patterns in document collections.
- Document collections in text mining can be static or dynamic, and a document can be a member of multiple collections.
- The presentation layer is important in text mining.
Preprocessing in Text Mining and Data Mining
- Data scrubbing and data normalization are both preprocessing tasks in data mining and text mining, involving similar tasks.
- The main purpose of data normalization is not to maximize duplicated data.
Patterns in Data Mining
- A pattern in data mining means that the data are correlated, have a relationship, and are predictable.
- The primary goal of data mining and text mining is to discover patterns in the data sources.
