Title: In Search of Lost Time (stamps?): Diachronic Text Classification
using Supervised Learning and N-Gram Feature Representations

Abstract:
This talk discusses a recent submission (with Terrence Szymanski of The
Insight Centre) to the SemEval 2015 Shared Task on Diachronic Text
evaluation. We approach the task of assigning a date of publication to a
text as a multi-class classification problem. We extract features from a
collection of historical news texts at the letter, word, and syntactic
level, and use these to train a classifier on date-labeled training data.
We alsoincorporate date probabilities of syntactic features as estimated
from the Google Books Ngram corpus. Our system achieved the highest
performance of all systems on subtask 2: identifying texts by
specific time language use.

Venue: K2-008 DIT Kevin Street
Time: 4pm
