”A Rose by any other Name”. Exploiting Knowledge Graphs for Lexical Learning in Information Retrieval


November 5, 2019, ore 16:00-18:00.

Room Enzo Paci, Directorate of the Department of Philosophy, Via Festa del Perdono, 7, Milan


Abstract

Information retrieval (IR) systems need to constantly update their knowledge as objects and language change over time. Due to linguistic data sparsity in the long tail of search queries, learning lexical concepts resists standard embedding-based approaches. We propose a learning framework that leverages symbolic information as encoded in knowledge graphs, both as a source of prior knowledge over lexical meanings and as a means of generating experiments to update this prior. The proposed framework is a novel combination of two ideas from cognitive science, lexical learning as inference and optimal experiment design, for the purpose of ecient IR. In this talk, we introduce the key components of this system, discuss preliminary results in idealized settings and share our roadmap for future improvements.

Participation is strongly recommended to students of the Doctoral School in Philosophy and Human Sciences.
Everyone interested is welcome to attend
