A Pairwise Learning-to-Rank Algorithm is a supervised ranking algorithm that compares item pairs.
- Context:
- It can be implemented by a Pairwise LTR system (to solve a pairwise LTR task).
- It can range from being a Factorization-based Pairwise LTR Algorithm to being an SVM-based Pairwise LTR Algorithm to being ...

- In this case learning-to-rank problem is approximated by a classification problem — learning a binary classifier that can tell which document is better in a given pair of documents. The goal is to minimize average number of inversions in ranking.

- QUOTE: The paper is concerned with learning to rank, which is to construct a model or a function for ranking objects. Learning to rank is useful for document retrieval, collaborative filtering, and many other applications. Several methods for learning to rank have been proposed, which take object pairs as 'instances' in learning. We refer to them as the pairwise approach in this paper. ...
