Map<String, List<int>>? abstractInvertedIndex
getter/setter pair

The abstract of the work, as an inverted index, which encodes information about the abstract's words and their positions within the text. Like Microsoft Academic Graph, OpenAlex doesn't include plaintext abstracts due to legal constraints.

Newer works are more likely to have an abstract inverted index. For example, over 60% of works in 2022 have abstract data, compared to 45% for works older than 2000.

Implementation

@JsonKey(name: 'abstract_inverted_index')
Map<String, List<int>>? abstractInvertedIndex;
