D-REX: Dialogue Relation Extraction with Explanations

1 code implementation10 Sep 2021 Alon Albalak, Varun Embar, Yi-Lin Tuan, Lise Getoor, William Yang Wang

Existing research studies on cross-sentence relation extraction in long-form multi-party conversations aim to improve relation extraction without considering the explainability of such methods.

Local Explanation of Dialogue Response Generation

1 code implementation NeurIPS 2021 Yi-Lin Tuan, Connor Pryor, Wenhu Chen, Lise Getoor, William Yang Wang

To gain insights into the reasoning process of a generation model, we propose anew method, local explanation of response generation (LERG) that regards the explanations as the mutual interaction of segments in input and output sentences.

Contrastive Entity Linkage: Mining Variational Attributes from Large Catalogs for Entity Linkage

no code implementations AKBC 2020 Varun Embar, Bunyamin Sisman, Hao Wei, Xin Luna Dong, Christos Faloutsos, Lise Getoor

However, this task is challenging as the variational attributes are often present as a part of unstructured text and are domain dependent.

Estimating Aggregate Properties In Relational Networks With Unobserved Data

User Profiling Using Hinge-loss Markov Random Fields

no code implementations5 Jan 2020 Golnoosh Farnadi, Lise Getoor, Marie-Francine Moens, Martine De Cock

In this paper, we propose a mechanism to infer a variety of user characteristics, such as, age, gender and personality traits, which can then be compiled into a user profile.

Estimating Causal Effects of Tone in Online Debates

1 code implementation10 Jun 2019 Dhanya Sridhar, Lise Getoor

In this paper, we estimate the causal effect of reply tones in debates on linguistic and sentiment changes in subsequent responses.

Scalable Structure Learning for Probabilistic Soft Logic

no code implementations3 Jul 2018 Varun Embar, Dhanya Sridhar, Golnoosh Farnadi, Lise Getoor

We introduce a greedy search-based algorithm and a novel optimization method that trade-off scalability and approximations to the structure learning problem in varying ways.

Using Noisy Extractions to Discover Causal Knowledge

Adaptive Neighborhood Graph Construction for Inference in Multi-Relational Networks

no code implementations2 Jul 2016 Shobeir Fakhraei, Dhanya Sridhar, Jay Pujara, Lise Getoor

A neighborhood graph, which represents the instances as vertices and their relations as weighted edges, is the basis of many semi-supervised and relational models for node labeling and link prediction.

Value of Information Lattice: Exploiting Probabilistic Independence for Effective Feature Subset Acquisition

no code implementations16 Jan 2014 Mustafa Bilgic, Lise Getoor

We address the cost-sensitive feature acquisition problem, where misclassifying an instance is costly but the expected misclassification cost can be reduced by acquiring the values of the missing features.

Hinge-loss Markov Random Fields: Convex Inference for Structured Prediction

no code implementations26 Sep 2013 Stephen Bach, Bert Huang, Ben London, Lise Getoor

Graphical models for structured domains are powerful tools, but the computational complexities of combinatorial prediction spaces can force restrictions on models, or require approximate inference in order to be tractable.

Scalable Text and Link Analysis with Mixed-Topic Link Models

no code implementations28 Mar 2013 Yaojia Zhu, Xiaoran Yan, Lise Getoor, Cristopher Moore

The resulting model has the advantage that its parameters, including the mixture of topics of each document and the resulting overlapping communities, can be inferred with a simple and scalable expectation-maximization algorithm.
