abstract |
Recent works in the area of academic recommender systems have demonstrated the effectiveness
of co-citation and citation closeness in related-document recommendations. However,
documents recommended from such systems may drift away from the main theme of the
query document. In this work, we investigate whether incorporating the textual information
in close proximity to a citation as well as the citation position could reduce such
drifting and further increase the performance of the recommender system. To investigate
this, we run experiments with several recommendation methods on a newly created and
now publicly available dataset containing 53 million unique citation-based records.
We then conduct a user-based evaluation with domain-knowledgeable participants. Our
results show that a new method based on the combination of Citation Proximity Analysis
(CPA), topic modelling and word embeddings achieves more than 20% improvement in Normalised
Discounted Cumulative Gain (nDCG) compared to CPA. |
