Abstract

Keywords are list of significant words or terms that best present the document context in brief and relate to the textual context. Extraction models are categorized into either statistical, linguistic, machine learning or a combination of these approaches. This paper introduces a model for extracting keywords based on their relatedness weight among the entire text terms. Strength of terms relationship is evaluated by semantic similarity. Document terms are assigned a weighted metric based on the likeness of their meaning content. Terms that are strongly co-related to each other are highly considered in individual terms semantic similarity. Provision of the overall terms similarity is crucial for defining relevant keywords that most expressing the text in both frequency and weighted likeness. Keywords are recursively evaluated according to their cohesion to each other and to the document context. The proposed model showed enhanced precision and recall extraction values over other approaches.
