The tf-idf is an algorithm which is generally used where massive data processing is done. Tf-idf is the weight given to a particular term within a document and it is proportional to the importance of the term. This paper aims to use the idea behind the tf-idf algorithm to design the df-icf algorithm which finds the importance of a particular document within the given corpus. General Terms DF-IC...

Objectives of this review are to define criteria for evaluating insoluble dietary fiber (IDF) methods, discuss their relevance in meeting the nutritional needs of ruminants and herbivores, describe problems with empirical IDF methods, and assess their relative merits. The challenge for the researcher, nutritionist, and analyst is to select fiber methods that are relevant and reproducible. Witho...

INTRODUCTION Full text searching over a database of moderate size often uses the inverse document frequency, idf = log(N/df), as a component in term weighting functions used for document indexing and retrieval. However, in very large databases (e.g. internet search engines), there is the potential that the collection size (N) could dominate the idf value, decreasing the usefulness of idf as a t...
