Lexical Substitution has a noticeable evolution in the literature,
mainly in the data sources used for the generation of substitutes
that feed the process. Of course, dictionaries and thesauri are widely
used for grouping synonyms in their structure, but the polysemy of
words prevents a direct exchange of terms without analyzing the
context. Vector space models, such as embeddings, are used to rep-
resent substitutes and also contexts. However, the representation of
words considering only contextual factors, in many cases, may in-
cur the approximation of terms that are not exactly synonyms. The
characteristics mentioned above suggest that the simultaneous use
of dictionaries and embeddings is a promising alternative for the
process. Thus, we present a method using information contained in
merged dictionaries, in addition to their linguistic relations struc-
tured in taxonomies. The method measures the preservation of the
meaning of the sentence with the potential synonym by observing
its frequency of application in small contexts. In addition, we also
consider a complete context to generate input from vector opera-
tions highlighting the best synonyms in a previously selected set.
The results show the efficiency of the method, surpassing many
methods consolidated in the literature in the prediction of the best
substitute for words contained in instances of a known benchmark.
