A Semi-Supervised Learning Approach for Morpheme Segmentation for an Arabic Dialect
We evaluate our approach by applying morpheme segmentation to the training data of a statistical machine translation (SMT) system. Experiments show that our approach is less sensitive to the availability…

Advances in Mandarin Broadcast Speech Recognition
We describe our continuing efforts to improve the UW-SRI-ICSI Mandarin broadcast speech recognizer.

IraqComm: A Next Generation Translation System
This paper describes the IraqComm translation system that mediates and translates spontaneous conversations between an English speaker and a speaker of colloquial Iraqi Arabic.

Detecting Deception Using Critical Segments
We present an investigation of segments that map to GLOBAL LIES, that is, the intent to deceive with respect to salient topics of the discourse. We propose that identifying the…

Duration and Pronunciation Conditioned Lexical Modeling for Speaker Verification
We propose a method to improve speaker recognition lexical model performance using acoustic-prosodic information. More specifically, the lexical model is trained using duration- and pronunciation-conditioned word N-grams, simultaneously modeling lexical…

fMPE-MAP: Improved Discriminative Adaptation for Modeling New Domains
This paper introduces a new adaptation approach, fMPE-MAP, which is an extension to the original fMPE (feature minimum phone error) algorithm, with the enhanced ability in porting Gaussian models and…

Leveraging graph locality via abstraction
The use of abstraction to speedup problem solving is ubiquitous in AI, especially in the field of heuristic search where abstraction has proven a crucial technique for creating highly accurate…

Regression testing for grammar-based systems
This paper describes best practices in two closely related regression testing frameworks used in grammar-based systems: MedSLT, a spoken language translation system based on the Regulus platform, and a search…

An LFG Chinese grammar for machine use
This paper describes the Chinese grammar developed at PARC, including its three basic components: the tokenizer and tagger, lexicon and syntactic rules.

PARC’s Bridge question answering system
This paper describes a system designed to robustly map from natural language sentences to logical, abstract knowledge representations (the Bridge system).
