Which of the following is an opinion, as defined in text mining?

Question

BlackTom AI · Accepted Answer

The question asks which option corresponds to an opinion, as defined in text mining, among the given choices.
Option 1: [place, sentiment, polarity, time]. Here, 'place' is used instead of the typical 'target' of the opinion, and 'polarity' is a related concept but not the standard labeling for the core opinion structure. The inclusion of 'place' and 'time' does not align with the common definition that opinions are about a target rather than a place, and the set does not match the usual components.
Option 2: [target, sentiment, holder, time]. This aligns with a widely used opinion-formation schema in text mining: the opinion has a target (what is being evaluated), the sentiment (the expressed positive/negative evaluation), the holder (who expresses the opinion), and the time (when the opinion is stated). This combination captures the full contextual elements of an opinion.
Option 3: [target, sentiment, polarity, intensity]. While this contains meaningful elements—target and sentiment are correct—the terms 'polarity' and 'intensity' replace 'holder' and 'time'. Polarity is often used synonymously with sentiment, but 'holder' (the author of the opinion) and 'time' are distinct and informative components that this option omits. Therefore this set is incomplete with respect to the defined opinion structure in many text-mining definitions.
Option 4: [place, sentiment, holder, intensity]. This includes 'holder' (which is good) and 'sentiment' (good), but uses 'place' instead of 'target' and 'intensity' instead of 'time'. The mismatch of 'place' and 'time' again makes this option misaligned with the standard opinion definition that centers on the target and the time of the opinion's expression.
In summary, Option 2 correctly captures the established elements of an opinion in text mining by including target, sentiment, holder, and time, while the other options substitute or omit essential components, leading to inaccuracies.
