Related to teachers' assessment and feedbacks from the four aspects, namely support, promotion, syllabus analysis and organization also indicate as at high rank.
For top returned concepts, a precision at high ranks (P0) of more than 80% is observed.
Tasks were shifted from different cadres of different specialities at high ranks to cadres at lower ranks.
Fruits that developed at high ranks, especially above a CPN value of 25, showed very low fibre quality in every aspect.
By obtaining PPI-related articles at high rank, researchers can more easily find the up-to-date PPI information, which cannot be found in manually curated PPI databases.
In both BASELINE and L1SVM, the self-rank distributions have a large peak at high ranks at a significant level (the P-value is almost zero), which means that both the methods are capable of predicting most known intermediate compounds correctly, compared with the random inference.
The second drawback of LCA, that is, the fact that it assigns many reads to taxa at high ranks, has been recently tackled in Clemente et al. (2010), where a method was proposed for assigning each read to a taxon at a rank lower (or equal) than the one selected by LCA.
The community does not appear to be primarily involved in lignocellulose degradation, but conservation of its members at high ranks suggests that these bacteria are beneficial to the host fitness and may contribute to insect nutrition, presumably by providing a fixed nitrogen source.
(i) LCA annotates a relatively small percentage of reads because a read is discarded if the least common taxon of its hits cannot be computed; (ii) LCA assigns many reads to taxa at high ranks, because it computes the lowest common ancestor of (possibly many) matching sequences (Kunin et al., 2008).
The best choice of approach in a given situation might depend on the expected degree of taxonomic novelty: for example, metagenomes with many taxa novel at high ranks might be better classified with a conservative approach, such as CARMA3 or an unsupervised approach, whereas metagenomes with close proxies could be confidently assigned using SPANNER.
