A deep learning model incorporating part of speech and self-matching attention for named entity recognition of Chinese electronic medical records

BMC Medical Informatics and Decision Making, 2019
Background The Named Entity Recognition (NER) task as a key step in the extraction of health information, has encountered many challenges in Chinese Electronic Medical Records (EMRs). Firstly, the casual use of Chinese abbreviations and doctors’ personal

Arabic POS Tagging: Don’t Abandon Feature Engineering Just Yet

WANLP@EACL, 2017
This paper focuses on comparing between using Support Vector Machine based ranking (SVM-Rank) and Bidirectional Long-Short-Term-Memory (bi-LSTM) neural-network based sequence labeling in building a state-of-the-art Arabic part-of-speech tagging system ...

A lipid‐sensitive food choice behavior influences aging outcomes from a longevity‐promoting diet

The FEBS Journal, EarlyView.
C. elegans are exposed to a variety of bacteria in their natural environment and must be able to distinguish between beneficial and detrimental food sources. We show that C. elegans exposed to the bacterium from their natural habitat, Methylobacterium, disrupts lipid homeostasis, causing worms to avoid this bacterial species and choose the laboratory ...

Similar Semantic Category Distributions but Distinct Noun Choices in Nonacademic Second Language Writing of Graduate Students With Different Disciplinary Backgrounds: A Natural Language Processing‐Based Analysis

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The disciplinary background of second language (L2) writers can shape their writing style, including their lexical choices. This study examines lexical differences in nonacademic argumentative essays on the same topic by L2‐English graduate students with humanities‐related or science‐related majors.

Character-level Supervision for Low-resource POS Tagging

DeepLo@ACL, 2018
Neural part-of-speech (POS) taggers are known to not perform well with little training data. As a step towards overcoming this problem, we present an architecture for learning more robust neural POS taggers by jointly training a hierarchical, recurrent ...

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

Journal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

Analysis and development of Urdu POS tagged corpus [PDF]

Proceedings of the 7th Workshop on Asian Language Resources - ALR7, 2009
In this paper, two corpora of Urdu (with 110K and 120K words) tagged with different POS tagsets are used to train TnT and Tree taggers. Error analysis of both taggers is done to identify frequent confusions in tagging. Based on the analysis of tagging, and syntactic structure of Urdu, a more refined tagset is derived.

MALAY PART OF SPEECH TAGGER: A COMPARATIVE STUDY ON TAGGING TOOLS

Asia-Pacific Journal of Information Technology and Multimedia, 2015
Malay language is an agglutinative language which rich morphology. Affixation to a root word is the most common morphological processes used to derive a new word for other meaning that would affect the change in their part of speech (POS ...

Transferring from Formal Newswire Domain with Hypernet for Twitter POS Tagging

Conference on Empirical Methods in Natural Language Processing, 2018
Part-of-Speech (POS) tagging for Twitter has received considerable attention in recent years. Because most POS tagging methods are based on supervised models, they usually require a large amount of labeled data for training. However, the existing labeled

Multifaceted Role of Multilevel Statistical and Linguistic Information From Target Language in Predicting Second Language Verb–Preposition and Verb–Particle Construction Production

Language Learning, EarlyView.
Abstract This study explores how statistical properties of verb–preposition and verb–particle constructions (VPCs) and their interplay in the target language shape second language (L2) production across L2 proficiency levels. We compared phrasal frequency and three contingency measures—mutual information (MI), forward delta P (ΔP), and backward ΔP—of ...
