Keyphrase Generation: A Multi-Aspect Survey
TABLE IV: KE scores on OAGKX (100K)
['[BOLD] Method', '[BOLD] F1@5', '[BOLD] F1@7', '[BOLD] F1@10']
For the evaluation, we used F1 score of full matches between predicted keyphrases from each method and those available in the data record (author keyphrases). We computed F1 scores on top 5, top 7 and top 10 returned keywords. Before comparing, both sets of terms were stemmed with Porter Stemmer and duplicates were removed. As we can see, the best of the three methods is YAKE, with top F1@10 score of 21.86 %. We also observed that RAKE was considerably faster than the two other methods.
