Term repetition abuse is considered an adversarial IR practice known as keyword spam. See list of practices we fought at AIRWEB at http://airweb.cse.lehigh.edu/2007/cfp.html
This tool can help you to write better titles, abstracts, descriptions, paragraphs, or full text by allowing you to detect and fix over-repeated terms. The tool uses a proprietary algorithm for detecting frequency-based spam.
Once detected, over-repeated terms can be edited by either reducing their term frequency or diluting the input by adding unique terms not present in the original text.
