Graphs, Computation, and Language

Graphs, Computation, and Language (GCL) is a series of tutorials by Dmitry Ustalov dedicated to human-computer interaction systems, graph theory, and computational linguistics. The tutorials discuss their real-world applications and elaborately go through the corresponding algorithms step-by-step.

Currently the GCL series includes two tutorials:

Crowdsourcing for Language Resources and Evaluation

Abstract

Crowdsourcing is an efficient approach for knowledge acquisition and data annotation that enables building impressive human-computer systems. In this tutorial we will discuss the relations between Crowdsourcing and Natural Language Processing, focusing on its practical use for Language Resource construction and evaluation. We will describe the established genres of crowdsourcing, show their strengths and weaknesses on real-world examples and case studies, and provide recommendations for ensuring the high quality of the crowdsourced annotation.

Graph Clustering for Natural Language Processing

Abstract

Graph-based representations are proven to be an effective approach for a variety of Natural Language Processing (NLP) tasks. Graph clustering makes it possible to extract useful knowledge by exploiting the implicit structure of the data. In this tutorial we will present several efficient graph clustering algorithms, show their strengths and weaknesses as well as their implementations and applications. Then, the evaluation methodology in unsupervised NLP tasks will be discussed.
