This paper presents a method for training SVM-based classification systems for combination with other existing classification systems designed for the same task.

We investigate the question of whether phone recognition models trained on large English databases can be used for speaker recognition in another language.

We discuss a named entity recognition system for Arabic, and show how we incorporated the information provided by MADA, a full morphological tagger which uses a morphological analyzer.

We investigate, through the transformation of human annotations into hypothetical idealized user interactions, the relative utility of various modes of user interaction and techniques for their interpretation.

We propose a new method for detecting out-of-vocabulary (OOV) words for large vocabulary continuous speech recognition (LVCSR) systems. Our method is based on performing a joint alignment between independently generated…

We present a sentence extraction algorithm for Information Distillation, a task where for a given templated query, relevant passages must be extracted from massive audio and textual document sources.

We explore the use of morph-based language models in large-vocabulary continuous speech recognition systems across four so-called “morphologically rich” languages: Finnish, Estonian, Turkish, and Egyptian Colloquial Arabic. The morphs are…

In this paper, we investigate the use of linguistically motivated and computationally efficient structured language models for reranking N-best hypotheses in a statistical machine translation system.

We describe a highly accurate large-vocabulary continuous Mandarin speech recognizer, a collaborative effort among four research organizations. Particularly, we build two acoustic models (AMs) with significant differences but with similar…

In this paper, we present a study – conducted in the context of the Halo Project – cataloging the types of failures that occur when capturing knowledge from natural language.

As part of the ongoing project, Project Halo, our goal is to build a system capable of answering questions posed by novice users to a formal knowledge base. In our…

We propose three methods for extending the Boosting family of classifiers motivated by the real-life problems we have encountered. Our results indicate that it is possible to obtain the same…
