Keyphrase extraction is a textual information processing task concerned with the automatic extraction of representative and characteristic phrases from a document that express all the key aspects of its content. Keyphrases constitute a succinct conceptual summary of a document, which is very useful in digital information management systems for semantic indexing, faceted search, document clustering and classification. This article introduces keyphrase extraction, provides a well‐structured… 

Multi-Document Keyphrase Extraction: A Literature Review and the First Dataset

TLDR
The first literature review and the first dataset for the task are presented, MK-DUC-01, which can serve as a new benchmark and several keyphrase extraction baselines are tested and show their results.

Multi-Document Keyphrase Extraction: Dataset, Baselines and Review

TLDR

CorpusRank: Corpus Information in Unsupervised Keyphrase Extraction

TLDR
This work extends their method by considering information from other documents in the corpus, and introduces a new keyphrase extraction algorithm, CorpusRank, which is based on document-phrase similarity drawn from the embedding space of BERT.

GLEAKE: Global and Local Embedding Automatic Keyphrase Extraction

TLDR
GLEAKE utilizes single and multi-word embedding techniques to explore the syntactic and semantic aspects of the candidate phrases and then combines them into a series of embedding-based graphs to refine the most significant phrases as a final set of keyphrases.

Unsupervised Keyphrase Extraction via Interpretable Neural Networks

TLDR
This work proposes INSPECT—a self-explaining neural framework for identifying influential keyphrases by measuring the predictive impact of input phrases on the downstream task of topic classification and suggests a new usage of interpretable neural networks as an intrinsic component in NLP systems, and not only as a tool for explaining model predictions to humans.
