Andrew Rosenberg

I am currently an Assistant Professor of Computer Science at Queens College (CUNY). I completed my Ph.D. at Columbia University in 2009.

My research concerns Natural Language Processing, Spoken Language Processing, Prosody/Intonation and Machine Learning.

Current Research Projects

AuToBI

Based on my dissertation, "Automatic Detection and Classification of Prosodic Events", I will incrementally release a system to generate hypothesized ToBI tones over the next few months. I am currently working to bringing the disparate components together to a single software package.

Most Recent Update (12-31-2009): Syllabifier -- An acoustic based pseudosyllable generator. Implemented in java, based on Villing et al.'s 2004 paper, Automatic Blind Syllable Segmentation for Continuous Speech.

Analysis of Non-native Intonation

Intonation is typically the last aspect of spoken language acquired by non-native speakers. In this work, we examine the influence of Mandarin Chinese speakers' native language on their perception and production of intonation in American English.

V-Measure: Cluster Evaluation Measure

Evaluating the success of clustering algorithms is not a trivial task. In 2007, I proposed a conditional entropy-based measure called V-measure at EMNLP. This measure is described in V-Measure: A conditional entropy-based external cluster evaluation measure. The name comes from its similarity in calculation to F-measure, and its goal of evaluating cluster validity.

V-measure is the evaluation measure for the unsupervised evaluation of the SemEval 2010 Word Sense Induction and Disambiguation Task

Distributed here is a java package that implements V-Measure as well as a number of other cluster evaluation measures. Feel free to email with bug reports and feature requests
