If it is not, the frequent terms are from a cluster of nonrelevant
documents and hence local feedback fails.
Articles not identified as relevant must be treated as nonrelevant
, making it impossible to compute reasonable values for search precision and recall.
by statistical analysis using word frequency counts comparing relevant and nonrelevant
We then tested the cDNA from 50 pathology-positive metastatic breast cancer lymph node samples and 27 healthy or nonrelevant
disease lymph node samples, respectively.
Here performance can be measured either in terms of precision and recall (which, in turn, refer to relevance), or by means of a decision-theoretic model which attributes different costs to the retrieval of relevant and nonrelevant
It also suggests that the ability of users to see the relevance of apparently nonrelevant
pieces of information is a key step in the discovery process.
The average ratings of abstracts returned by the filtering methods are not very high, considering the range of relevance ratings was from one for nonrelevant
TMs up to seven for very relevant TMs.
In our opinion, the proposed method will find applications in the following areas: (a) to distinguish between clinically relevant and nonrelevant
concentrations of PSA mRNA, the latter possibly occurring because of illegitimate transcription (28); (b) to provide information about the relation of PSA mRNA concentrations and recurrent disease after surgery; (c) as a powerful research tool in the study of the biology of prostate cancer and the metastatic process; and (d) PSA may be a new favorable prognostic indicator in female breast cancer, as has been found in recent years (29-32).
Within the confines of lexical similarity the test sets do provide a broad sample of query-document comparisons and are representative of the highly nontrivial task of separating the relevant from the nonrelevant
They found little correlation between a student's grade and the overall number of such phrases -- but they did find an "inverse correspondence between grade received and number of nonrelevant
prepositional phrases" (p.
The two measures of meaning attached to each value dimension by the respondent are used to distinguish the respondent's operative values from his adopted, intended, and nonrelevant
It may also decrease precision by retrieving nonrelevant
