These rules instruct the system to use semantically relevant elements of a text to identify relevant categories based on its content. Each rule consists of an antecedent or pattern and a predicted category.

What are the 8 levels of classification?

The classification system commonly used today is based on the Linnean system and has eight levels of taxa; from the most general to the most specific, these are domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.

What is the first level of classification?

Explanation: The first categorical level–called a taxonomic level–is the broadest. That means it includes the MOST organisms. By organisms we are including only cell-based organisms, so viruses, viroids and prions are not included.
