Abstract:
Keyphrase extraction is essential to many Information retrieval (IR) and Natural language Processing (NLP) tasks such as summarization and indexing. In this study, we investigate state-of-the-art approaches to keyphrase extraction on Arabic. We address the problem as sequence classifications and create a Bi-LSTM model to classify each token of the sequence to either part of the keyphrase or outside of any keyphrase. We extracted word embeddings from two pre-trained model which are Word2Vec and BERT. Moreover, we investigated the effect of incorporating linguistic, positional, and statistical features with word embeddings on the performance. Our best performing model has achieved 0.45 F1-score when combining linguistic and positional features with embedding generated from BERT.
