Leveraging graph-based semantic annotation for the identification of cause-effect relations

This research is related to language article in Indonesia that discuss about causality relationship research used as public health surveillance information monitoring system. Utilization of this research is suitability of feature selection, phrase annotation, paragraph annotation, medical element annotation and graph-based semantic annotation. Evaluation of system performance is done by intrinsic approach using the Naive Bayes Multinomial method. The results obtained sequentially for recall, precision and f-measure are 0.924, 0.905, and 0.910

A tool for enhancing MetaMap performance when annotating clinical guideline documents with UMLS concepts

We developed a tool that integrates the National Library of Medicine's MetaMap software with GATE, an open-source text an- alytics framework. The tool allows non-ASCII encoded documents of numerous formats to be annotated with UMLS concepts. We created a GATE pipeline to chunk cardiovascular disease guideline text into default segments (blank-line delimited), XML element content, sentences and phrases, which were sequentially submitted to MetaMap for annotation. XML element, sentence and phrase chunking allowed term extraction and mapping to be completed in around 1/3 of the time taken with de- fault chunking, although with slight loss of accuracy (F1.0s=0.94-0.99). However, phrase chunking allows more complex input to be processed in real time, which is not possible with the other approaches. We discuss the results in relation to use of MetaMap's --term processing option for generating pre- and post-coordinated mappings from composite phrases

Towards Bidirectional Hierarchical Representations for Attention-Based Neural Machine Translation

This paper proposes a hierarchical attentional neural translation model which focuses on enhancing source-side hierarchical representations by covering both local and global semantic information using a bidirectional tree-based encoder. To maximize the predictive likelihood of target words, a weighted variant of an attention mechanism is used to balance the attentive information between lexical and phrase vectors. Using a tree-based rare word encoding, the proposed model is extended to sub-word level to alleviate the out-of-vocabulary (OOV) problem. Empirical results reveal that the proposed model significantly outperforms sequence-to-sequence attention-based and tree-based neural translation models in English-Chinese translation tasks.Comment: Accepted for publication at EMNLP 201

Cultural specificities in Carnatic and Hindustani music: Commentary on the Saraga Open Dataset

This commentary explores features of the "Saraga" article and open dataset, discussing some of the issues arising. I argue that the CompMusic project and this resulting dataset are impressive for their sensitivity to cultural specificities of the Hindustani and Carnatic musical styles; for example, the dataset includes manual annotations based on music theoretical concepts from within the styles, rather than imposing conceptual categories from outside. However, I propose there are aspects of the dataset's manual annotations that require clarification in order for them to be used as ground truths by other researchers. In addition, I raise questions regarding the representativeness of the dataset – an issue that has ethical implications

Identification des unités de mesure dans les textes scientifiques

National audienceIdentification of units of measures in scientific texts. The work presented in this paper consists in identifying specialized terms (units of measures) in textual documents in order to enrich a onto-terminological resource (OTR). The first step permits to predict the localization of unit of measure variants in the documents. We have used a method based on supervised learning. This method permits to reduce significantly the variant search space staying in an optimal search context (reduction of 86% of the search space on the studied set of documents). The second step uses a new similarity measure identifying automatically variants associated with term denoting a unit of measure already present in the OTR with a precision rate of 82% for a threshold above 0.6 on the studied corpus.Le travail présenté dans cet article se situe dans le cadre de l'identification de termes spécialisés (unités de mesure) à partir de données textuelles pour enrichir une Ressource Termino-Ontologique (RTO). La première étape de notre méthode consiste à prédire la localisation des variants d'unités de mesure dans les documents. Nous avons utilisé une méthode reposant sur l'apprentissage supervisé. Cette méthode permet de réduire sensiblement l'espace de recherche des variants tout en restant dans un contexte optimal de recherche (réduction de 86% de l'espace de recherché sur le corpus étudié). La deuxième étape du processus, une fois l'espace de recherche réduit aux variants d'unités, utilise une nouvelle mesure de similarité permettant d'identifier automatiquement les variants découverts par rapport à un terme d'unité déjà référencé dans la RTO avec un taux de précision de 82% pour un seuil au dessus de 0.6 sur le corpus étudié
