Bidirectional Sequence Classification for Tagging Tasks with Guided Learning

نویسنده

  • Andrea Gesmundo
چکیده

In this paper we present a series of adaptations of the Guided Learning framework to solve different tagging tasks. The specificity of the proposed system lies in its ability to learn the order of inference together with the parameters of the local classifier instead of forcing it into a pre-defined order (left-to-right). The training algorithm is based on the Perceptron Algorithm. We apply the system to different kinds of tagging tasks reaching state of the art results with short execution time. Mots-clés : Bidirectionnel, Classification de Séquence, Apprentissage Guidé.

Guided Learning for Bidirectional Sequence Classification

In this paper, we propose guided learning, a new learning framework for bidirectional sequence classification. The tasks of learning the order of inference and training the local classifier are dynamically incorporated into a single Perceptron like learning algorithm. We apply this novel learning algorithm to POS tagging. It obtains an error rate of 2.67% on the standard PTB test set, which rep...

Lemmatising Serbian as Category Tagging with Bidirectional Sequence Classification

We present a novel tool for morphological analysis of Serbian, which is a low-resource language with rich morphology. Our tool produces lemmatisation and morphological analysis reaching accuracy that is considerably higher compared to the existing alternative tools: 83.6% relative error reduction on lemmatisation and 8.1% relative error reduction on morphological analysis. The system is trained...

Bi-directional LSTM-CNNs-CRF for Italian Sequence Labeling

English. In this paper, we propose a Deep Learning architecture for sequence labeling based on a state of the art model that exploits both wordand characterlevel representations through the combination of bidirectional LSTM, CNN and CRF. We evaluate the proposed method on three Natural Language Processing tasks for Italian: PoS-tagging of tweets, Named Entity Recognition and Super-Sense Tagging...

Bidirectional Inference with the Easiest-First Strategy for Tagging Sequence Data

This paper presents a bidirectional inference algorithm for sequence labeling problems such as part-of-speech tagging, named entity recognition and text chunking. The algorithm can enumerate all possible decomposition structures and find the highest probability sequence together with the corresponding decomposition structure in polynomial time. We also present an efficient decoding algorithm ba...

Semi-supervised sequence tagging with bidirectional language models

Pre-trained word embeddings learned from unlabeled text have become a standard component of neural network architectures for NLP tasks. However, in most cases, the recurrent network that operates on word-level representations to produce context sensitive representations is trained on relatively little labeled data. In this paper, we demonstrate a general semi-supervised approach for adding pret...
