“…Given appropriate term selection and weighting, the BOW model can produce cognitively plausible results (Westerman et al, 2010;Lee et al, 2005). However, the validity of resultant similarities can be compromised by vocabulary mismatch, which is the tendency for different words to be used to express the same concepts (Furnas, Landauer, Gomez, & Dumais, 1987).As terms are deemed independent, the semantic relationship between documents using synonymous or semantically related terms will remain obscured, wrongly suppressing similarity measures.…”
