Textual ETL: An Important Component in the IT Ecosystem

Simply put, unstructured content becomes much more useful to applications such as Business Intelligence, Enterprise Search, or "big data" analysis, through the addition of structure.

In other words, structuring the unstructured.

Textual ETL:  This is one of a number of labels that can be attached to this process. It involves the processing of text. For example:

  • To Identify idioms and important entities, and record these as metadata (additional structure)
  • To identify of "parts-of-speech". Generally nouns are more important than other word types. Also, combinations of different parts-of-speech can indicate meaning or intent within a sentence

These capabilities are language dependent.

    Most applications require more than than just core text processing capabilities

    • Cleaning:  The removal of extraneous or misleading content, such as html menus, or headers and footers, is important to quality. Cleaning should be done prior to text processing
    • Normalization: This applies to dates, times, phone numbers and other entities, and also to the format and arrangement of the metadata output from the textual ETL process
