coeficiente
quotient ; coefficient.
One reads, for instance, that a parameter in assessing the maximum period a user can be kept waiting is the 'aggravation quotient'.
The coefficients of eigenvectors associated with the largest eigenvalue provide the basis for sequencing atoms which are ordered according to the relative magnitudes of the coefficients.
coeficiente de correlación
correlation coefficient
These and various correlation coefficients are discussed and the type of conclusions to be drawn are pointed out.
coeficiente de correlación de Pearson
Pearson correlation coefficient
The Pearson correlation coefficient has been calculated to find out the correlation and to test the null hypothesis that there is no correlation among publishing in journals, citing from journals and use of journals by a defined set of researchers.
coeficiente de exhaustividad [Relación entre el número de documentos pertinentes recuperados y el número total de documentos pertinentes en el sistema]
coefficient of recall
recall ratio
This article presents a method which makes it possible to calculate the fuzzy coefficient of precision and fuzzy coefficient of recall.
The recall ratio is the number of relevant documents retrieved, in proportion to the total number of relevant documents in the collection.
coeficiente de inteligencia
IQ (intelligence quotient)
He was a precocious seventh grader who had demonstrated an IQ of 145, thus placing him intellectually far ahead of his co-students.
coeficiente de irrelevancia [Indice que se obtiene de dividir los documentos recuperados e irrelevantes a la pregunta y el total de documentos irrelevantes contenidos en la colección]
fallout ratio
The fallout ratio is particularly useful when comparing performances of document collections of different sizes.
coeficiente de la correlación de los cosenos
cosine correlation coefficient
A query is treated in the same way, and the query vector is then compared with the document vectors, using the cosine correlation coefficient to give a measure of the extent to which they coincide.
coeficiente de pertinencia [Relación existente entre el número de documentos pertinentes obtenidos y el número total de documentos pertinentes y no pertinentes]
precision ratio
relevance rating
relevance ranking
The precision ratio (originally called the relevance ratio) is the number of relevant documents retrieved, in proportion to the total number of documents searched and retrieved and its formula is: precision ratio = number of relevant documents retrieved / total number of documents retrieved X 100%.
Various scales of relevance ratings may be established.
SABRE (Semi-Automated Bibliographic Environment) provides semi-automatic relevance ranking of citations obtained from bibliographic data base searches.
coeficiente de precisión
coefficient of precision
This article presents a method which makes it possible to calculate the fuzzy coefficient of precision and fuzzy coefficient of recall.
coeficiente de referencia conjunta [Valor de afinidad temática entre publicaciones en función del número de veces que han sido citadas conjuntamente]
cocitation strength
Using the random graph hypothesis, the statistical validity of co-citation graphs has been investigated as a function of co-citation strength for a given value of citation frequency.
coeficiente de similitud [Medida usada para determinar la afinidad temática de varias publicaciones en base al número de citas bibliográficas que tienen en común y al número de veces que han sido citadas conjuntamente]
similarity measure
A further refinement is to use a combination of bibliographic coupling and co-citation to give a 'similarity measure', which gives better results in terms of relevance than either method on its own.
coeficiente intelectual
IQ (intelligence quotient)
He was a precocious seventh grader who had demonstrated an IQ of 145, thus placing him intellectually far ahead of his co-students.
