Single Document Automatic Text Summarization using Term Frequency-Inverse Document Frequency (TF-IDF) [PDF]

open access: yesComTech: Computer, Mathematics and Engineering Applications, 2016
The increasing availability of online information has triggered an intensive research in the area of automatic text summarization within the Natural Language Processing (NLP). Text summarization reduces the text by removing the less useful information which helps the reader to find the required information quickly.

A study of the Dirichlet Priors for term frequency normalisation [PDF]

open access: yes, 2005
In Information Retrieval (IR), the Dirichlet Priors have been applied to the smoothing technique of the language modeling approach. In this paper, we apply the Dirichlet Priors to the term frequency normalisation of the classical BM25 probabilistic model
