Title: Natural Language Interface to Data

Time: 8:30 – 10:00

Abstract: A large amount of the world’s data is stored in relational databases and knowledge graphs. One has to either learn programming languages like Structured Query Language (SQL) or reply on canned query forms to query data, even for very simple queries. SQL and SPARQL are the most commonly used interface for accessing relational databases and knowledge graphs, respectively. However, it requires users to acquire good understanding of such query languages, data schema, and database running environment, which could take long training time and is not practical for users who query data occasionally. In this tutorial, I will give an introduction of research progress in this area and discuss future research directions.

Title: From Data to Model Programming: Injecting Structured Priors for Knowledge Extraction

Time: 10:30-12:00

Abstract: Deep neural models have achieved state-of-the-art performance on knowledge extraction tasks, from sequence tagging, to relation extraction, and knowledge reasoning. Yet, these data-hungry models have heavy reliance on human-labeled training data and often operate as “black-box” components, slowing down the development of downstream applications.

In this talk, I will introduce our recent advances on imposing structured prior knowledge into deep neural models for knowledge extraction, both at the input data level (i.e., programming the “data”) and at the model architecture level (i.e., programming the “model”). In particular, I will discuss how to faithfully incorporate domain dictionaries in named entity recognition and how to softly ground semantic rules in relation extraction, as examples of input-level structured priors. Towards model programming, I will present a graph neural network-based framework, for capturing multi-relational structured priors as part of the model architecture in natural language inference that involves commonsense reasoning. Together, these solutions form a roadmap for going from “data” to “model” programming with structured priors.

Title: Deep Learning for Graphs: Models and Applications

Time: 14:00-17:30

Abstract: Graphs provide a universal representation of data with numerous types while deep learning has demonstrated immense ability in representation learning. Thus, bridging deep learning with graphs presents astounding opportunities to enable general solutions for a variety of real-world problems. However, traditional deep learning techniques that were disruptive for regular grid data such as images and sequences are not immediately applicable to graph-structured data. Therefore, marrying these two areas faces tremendous challenges. In this tutorial, I will provide a comprehensive overview of recent advances in deep learning for graphs including both models and applications. In particular, I will introduce some basic concepts, review state of the art algorithms, and illustrate various important applications. Finally, I will summarize the tutorial with discussions on open issues and challenges.

Title:  Tutorial on Explainable Recommendation and Search

Time: 8:30 – 12:00

Abstract: Explainable recommendation and search attempt to develop models or methods that not only generate high-quality recommendation or search results, but also intuitive explanations of the results for users or system designers, which can help to improve the system transparency, persuasiveness, trustworthiness, fairness and effectiveness. This is even more important in personalized search and recommendation scenarios, where users would like to know why a particular product, web page, news report, or friend suggestion exists in his or her own search and recommendation lists. The tutorial focuses on the research and application of explainable recommendation and search algorithms, as well as their application in real-world systems such as search engine, e-commerce and social networks. The tutorial aims at introducing and communicating explainable recommendation and search methods to the community, as well as gathering researchers and practitioners interested in this research direction for discussions, idea communications, and research promotions.
