While the resolution of term ambiguity is important for information extraction (IE) systems, the cost of resolving each in- stance of an entity can be prohibitively expensive on large datasets. To combat this, this work looks at ambiguity detec- tion at the term, rather than the instance, level. By making a judgment about the general ambiguity of a term, a system is able to handle ambiguous and unambigu- ous cases differently, improving through- put and quality. To address the term ambiguity detection problem, we employ a model that combines data from lan- guage models, ontologies, and topic mod- eling. Results over a dataset of entities from four product domains show that the proposed approach achieves significantly above baseline F-measure of 0.96.
