Text data are an important source of detailed information about social and political events. Automated systems parse large volumes of text data to infer or extract structured information that describes actors, actions, dates, times, and locations. One of these sub-tasks is geocoding: predicting the geographic coordinates associated with events or locations described by a given text. I present an end-to-end probabilistic model for geocoding text data. Additionally, I collect a novel data set for…

Lost in Space: Geolocation in Event Data
TLDR
A two-stage supervised machine-learning algorithm that evaluates each location mention to be either correct or incorrect is introduced and shows that the proposed algorithm outperforms existing geocoders even in a case added post hoc to test the generality of the developed algorithm.
Mordecai: Full Text Geoparsing and Event Geocoding
Mordecai is a new full-text geoparsing system that extracts place names from text, resolves them to their correct entries in a gazetteer, and returns structured geographic information for the…
Spatial Language Representation with Multi-Level Geocoding
TLDR
A multi-level geocoding model (MLG) that learns to associate texts to geographic locations and can effectively learn the connection between text spans and coordinates - and thus can be extended to toponymns not present in knowledge bases.
Distributed Representations of Words and Phrases and their Compositionality
TLDR
This paper presents a simple method for finding phrases in text, and shows that learning good vector representations for millions of phrases is possible and describes a simple alternative to the hierarchical softmax called negative sampling.
Cross-Lingual Ability of Multilingual BERT: An Empirical Study
TLDR
A comprehensive study of the contribution of different components in M-BERT to its cross-lingual ability, finding that the lexical overlap between languages plays a negligible role, while the depth of the network is an integral part of it.
DistilBERT, a distilled version of BERT: smaller, faster, cheaper and lighter
TLDR
This work proposes a method to pre-train a smaller general-purpose language representation model, called DistilBERT, which can be fine-tuned with good performances on a wide range of tasks like its larger counterparts, and introduces a triple loss combining language modeling, distillation and cosine-distance losses.
Adam: A Method for Stochastic Optimization
TLDR
This work introduces Adam, an algorithm for first-order gradient-based optimization of stochastic objective functions, based on adaptive estimates of lower-order moments, and provides a regret bound on the convergence rate that is comparable to the best known results under the online convex optimization framework.
Attention is All you Need
TLDR
A new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely is proposed, which generalizes well to other tasks by applying it successfully to English constituency parsing both with large and limited training data.
RoBERTa: A Robustly Optimized BERT Pretraining Approach
TLDR
It is found that BERT was significantly undertrained, and can match or exceed the performance of every model published after it, and the best model achieves state-of-the-art results on GLUE, RACE and SQuAD.
