Research paper thumbnail of Inferring activity time in news through event modeling

Proceedings of the 46th Annual Meeting of the Association for Computational Linguistics on Human Language Technologies Student Research Workshop - HLT '08, 2008

Creating an ef- fective algorithm for identifying the activ- ity time of an event in news is difficult in part because of the sparsity of explicit tem- poral expressions. This paper describes a domain-independent machine-learning based

We report on its use in the WMT 2011 Haitian Creole to English trans-lation task, showing that MonoTrans2 trans-lated 38% of the sentences well compared to Google Translate's 25%.

In this paper we propose a fuzzy algebraic framework where the valuating sets are other than the unit interval (lattices, partially ordered sets or relational structures) . This provides for a flexible organization of the information gathered by the agent (via interactions with the environment and/or other agents) and enables its selected use when different drives are active. Agents (Petitagé, ANNA, POPSICLE and Izbushka) , which are instantiations of our model, are also given in order to illustrate the use of this framework, as well as its possible extensions.

Research paper thumbnail of Improving a simple bigram HMM part-of-speech tagger by latent annotation and self-training

Proceedings of Human Language Technologies: The 2009 Annual Conference of the North American Chapter of the Association for Computational Linguistics, Companion Volume: Short Papers on - NAACL '09, 2009

The use of latent annotations substantially improves the performance of a baseline HMM bigram tagger, outperforming a trigram HMM tagger with sophisticated smoothing. The performance of the latent tagger is further enhanced by self-training with a large set of unlabeled data, even in situations where standard bigram or trigram taggers do not benefit from selftraining when trained on greater amounts of labeled training data. Our best model obtains a state-of-the-art Chinese tagging accuracy of 94.78% when evaluated on a representative test set of the Penn Chinese Treebank 6.0.

Working within cdec, an open source modular framework for machine translation, we explore the benefits of several modifications to our hierarchical phrase-based model, including segmentation lattices, minimum Bayes Risk decoding, grammar extraction methods, and varying language models. Furthermore, we analyze decoder speed and memory performance across our set of models and show there is an important trade-off that needs to be made.

We analyze the performance of state-of-the-art tagging models, either generative or discriminative, left-to-right or bidirectional, with or without latent annotations, together with the use of ToBI break indexes and several methods for segmenting the speech transcripts (i.e., conversation side, speaker turn, or humanannotated sentence). Based on these studies, we observe that: (1) bidirectional models tend to achieve better accuracy levels than left-toright models, (2) generative models seem to perform somewhat better than discriminative models on this task, and (3) prosody improves tagging performance of models on conversation sides, but has much less impact on smaller segments. We conclude that, although the use of break indexes can indeed significantly improve performance over baseline models without them on conversation sides, tagging accuracy improves more by using smaller segments, for which the impact of the break indexes is marginal.

Unfortunately these successes have not been uniform; closely related language pairs can be translated with a high degree of precision, while for distant pairs the result is far from acceptable. Models which have been most successful for translating between structurally divergent language pairs have been based on synchronous grammars. A critical component of these translation models is their grammar which encodes translational ...
