In-Session Personalization for Talent Search
Sahin Cem Geyik, Vijay Dialani, Meng Meng, Ryan Smith

TL;DR
This paper introduces an in-session personalized candidate recommendation system for talent search that dynamically updates suggestions based on user feedback, improving relevance even with minimal initial input.
Contribution
It proposes a novel in-session personalization framework combining intent clustering and multi-armed bandits, with online learning to adapt recommendations during the search session.
Findings
Offline experiments show improved candidate relevance.
Online deployment demonstrates effective real-time personalization.
Method outperforms traditional static recommendation models.
Abstract
Previous efforts in recommendation of candidates for talent search followed the general pattern of receiving an initial search criteria and generating a set of candidates utilizing a pre-trained model. Traditionally, the generated recommendations are final, that is, the list of potential candidates is not modified unless the user explicitly changes his/her search criteria. In this paper, we are proposing a candidate recommendation model which takes into account the immediate feedback of the user, and updates the candidate recommendations at each step. This setting also allows for very uninformative initial search queries, since we pinpoint the user's intent due to the feedback during the search session. To achieve our goal, we employ an intent clustering method based on topic modeling which separates the candidate space into meaningful, possibly overlapping, subsets (which we call…
