TAXONOMIC PROPERTY

Intrinsic Property-based Taxonomic Relation Extraction from Category Structure

We propose a novel algorithm to extract taxonomic (or isa/instanceOf ) relations from category structure by classifying each category link. Previous algorithms mainly focus on lexical patterns of category names to classify whether or not a given category link is an isa/instanceOf. In contrast, our algorithm extracts intrinsic properties that represent the definition of given category name, and ...

Stability of operational taxonomic units: an important but neglected property for analyzing microbial diversity

BACKGROUND The operational taxonomic unit (OTU) is widely used in microbial ecology. Reproducibility in microbial ecology research depends on the reliability of OTU-based 16S ribosomal subunit RNA (rRNA) analyses. RESULTS Here, we report that many hierarchical and greedy clustering methods produce unstable OTUs, with membership that depends on the number of sequences clustered. If OTUs are re...

Taxonomic Reasoning

In formalizing knowledge for common sense reasoning, one often needs to partition some domain. An instance of this from the Blocks World is the statement "All blocks are either held, on the table, or on another block." Although we can write this axiom in predicate calculus or in clause form for input to a theorem prover, such representations are highly space inefficient. In this paper we presen...
