The application of Word Sense Disambiguation (WSD) is usually deter- mined exclusively by the trust in the disambiguation system used. In this paper, a study in the Information Retrieval (IR) field is carried out about the impact of others factors in WSD such as the confidence of the WSD tool, the grade of polisemy or granularity and the difference in the discrimination strength between the original term and the disambiguated one. Thus, a proposal to decide whether a word should be disambiguated or not according to Inverse Document Frequency (IDF) is pre- sented. Finally, it is shown that a selective disambiguation based on IDF improves slightly the performance of an IR system.
