    Computational Linguistic Analysis of Earthquake Collections
    Bialousz, Kenneth; Kokal, Kevin; Orleans-Pobee, Kwamina; Wakeley, Christopher (2014-12)
    CS4984 is a newly-offered class at Virginia Tech with a unit based, project-problem based learning curriculum. This class style is based on NSF-funded work on curriculum for the field of digital libraries and related topics, and in this class, is used to guide a student based investigation of computational linguistics. The specific problem this report addresses is the creation of a means to automatically generate a short summary of a corpus of articles about earthquakes. Such a summary should be best representative of the texts and include all relevant information about earthquakes. For our analysis, we operated on two corpora--one about a 5.8 magnitude earthquake in Virginia in August 2011, and another about a 6.6 magnitude earthquake in April 2013 in Lushan, China. Techniques used to analyze the articles include clustering, lemmatization, frequency analysis of n-grams, and regular expression searches.
