We present Tripadvisor Restaurant 2020 (TripR-2020) dataset, a new set of reviews from Tripadvisor referred to restaurants located in the city of London.

Trip-2020 dataset provides the reviews of 1,428 experts evaluating 78 restaurants. Not all experts evaluate all the restaurants. The dataset collects 8,306 reviews. In particular, each review is given by attributes:

• Concerning the restaurant: name, identifier code, location name, and location identifier code.
• Concerning the expert: name, identifier code, and location name.
• Concerning the review: title, body, date, general rating, food rating, service rating, and value rating.

For the evaluation of the Sentiment Analysis based Multi-person Multi-criteria Decision Making (SA-MpMcDM) methodology, a reduction of the TripR-2020 dataset has been analyzed. Specifically, 4 restaurants are evaluated by 6 experts. The six experts evaluate the four restaurants providing a total of 24 reviews and avoiding the loss of information.

The dataset is annotated following the official SemEval-2016 annotation manual. We show the main features of the annotation:

The 24 reviews from the dataset are split into 168 sentences. We labelled 185 opinions of which 149 are positive, 26 are negative and the rest are neutral opinions. Each sentence can have at least an aspect category annotated (Restaurant, Food, Service, Drinks, Ambience and Location).

We show an example of annotation of a review from the TripR-2020 dataset:

The review is split into sentences. First column presents the text of the sentence. Second column is referred to the aspect terms discussed in the sentence. The aspect is implicit when the aspect term is not explicitly mentioned in the sentence. Third column is the aspect category to which the aspect term is categorized. Fourth column is the sentiment polarity about each aspect category.
