In recent decades, the vast majority of researchers in the field of information retrieval (IR) have been studying three main categories of IR models (i.e., vector space models, probabilistic models and statistical language models). Recently, some researchers have been exploring a new category of IR models which introduce the knowledge from the field of digital signal processing (DSP), which have been shown to be promising. However, the existing DSP-based models are not well-performed in some cases because they have not incorporated effective term weighting methods and the existing framework it...
