Automatic Extraction of Linguistic Metaphors with LDA Topic Modeling
نویسندگان
چکیده
We aim to investigate cross-cultural patterns of thought through cross-linguistic investigation of the use of metaphor. As a first step, we produce a system for locating instances of metaphor in English and Spanish text. In contrast to previous work which relies on resources like syntactic parsing and WordNet, our system is based on LDA topic modeling, enabling its application even to low-resource languages, and requires no labeled data. We achieve an F-score of 59% for English.

This project investigates the applicability of image annotation algorithms based on Latent Dirichlet Allocation (LDA) to a task different from the one for which they were originally designed: visual object categorization. We developed a topic model which is based on an existing approach and evaluated its performance on four datasets which we created from the PASCAL database using different feat...
