Use of a multi-way method to analyze the amino acid composition of a conserved group of orthologous proteins in prokaryotes.

abstract：BACKGROUND:The biomedical literature continues to grow at a rapid pace, making the challenge of knowledge retrieval and extraction ever greater. Tools that provide a means to search and mine the full text of literature thus represent an important way by which the efficiency of these processes can be improved. RESULTS:...
