NewsMTSC dataset

NewsMTSC is a high-quality dataset consisting of more than 11k manually labeled sentences sampled from English news articles. Each sentence was labeled by five human coders (the dataset contains only examples where the five coders assessed same or similar sentiment). The dataset is published as a full paper at EACL 2021: NewsMTSC: (Multi-)Target-dependent Sentiment Classification in News Articles.

Subsets and splits

The dataset consists of two subsets (rw and mt), each consisting of three splits (train, validation, and test). We recommend to use the rw subset, which is also the default subset. Both subsets share the same train set, in which the three sentiment classes have similar frequency since we applied class boosting. The two subsets differ in their validation and test sets: rw contains validation and test sets that resemble real-world distribution of sentiment in news articles. In contrast, mt's validation and test sets contain only sentences that each have two or more (different) targets, where each target's sentiment was labeled individually.

More information on the subsets can be found in our paper.

Format

Each split is stored in a JSONL file. In JSONL, each line represents one JSON object. In our dataset, each JSON object consists of the following attributes. When using the dataset, you most likely will need (only) the attributes highlighted in bold.

  1. mention: text of the mention within sentence
  2. polarity: sentiment of the sentence concerning the target's mention (-1 = negative, 0 = neutral, 1 = positive)
  3. from: character-based, 0-indexed position of the first character of the target's mention within sentence
  4. to: last character of the target's mention
  5. sentence: sentence
  6. id: identifier that is unique within NewsMTSC
