Decision Strategies for Incremental POS Tagging
نویسندگان
چکیده
In an incremental NLP pipeline every module needs to work incrementally. However, an incremental processing mode can lead to a degradation of accuracy due to the missing context to the right. We discuss three properties of incremental output that can be traded for accuracy, namely timeliness, monotonicity and decisiveness. The consequences of these trade-offs are evaluated systematically for the task of part-of-speech tagging.

An improved joint model: POS tagging and dependency parsing
Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...

Abstract: Part-Of-Speech (POS) tagging is essential work for many models and methods in other areas in natural language processing such as machine translation, spell checker, text-to-speech, automatic speech recognition, etc. So far, high accurate POS taggers have been created in many languages. In this paper, we focus on POS tagging in the Persian language. Because of problems in Persian POS t...
متن کاملAdaptive Latency for Part-of-Speech Tagging in Incremental Text-to-Speech Synthesis
Incremental text-to-speech systems aim at synthesizing a text ’on-the-fly’, while the user is typing a sentence. In this context, this article addresses the problem of the part-of-speech tagging (POS, i.e. lexical category) which is a critical step for accurate grapheme-to-phoneme conversion and prosody estimation. Here, the main challenge is to estimate the POS of a given word without knowing ...
متن کاملIncremental Joint POS Tagging and Dependency Parsing in Chinese
We address the problem of joint part-of-speech (POS) tagging and dependency parsing in Chinese. In Chinese, some POS tags are often hard to disambiguate without considering longrange syntactic information. Also, the traditional pipeline approach to POS tagging and dependency parsing may suffer from the problem of error propagation. In this paper, we propose the first incremental approach to the...
متن کاملIncremental Joint Approach to Word Segmentation, POS Tagging, and Dependency Parsing in Chinese
We propose the first joint model for word segmentation, POS tagging, and dependency parsing for Chinese. Based on an extension of the incremental joint model for POS tagging and dependency parsing (Hatori et al., 2011), we propose an efficient character-based decoding method that can combine features from state-of-the-art segmentation, POS tagging, and dependency parsing models. We also describ...
