Handcrafted feature methods were employed for this task given a little success since they are limited by the scope of the expert. Lately, deep learning-based methods have been employed to solve this issue. However, most architectures used for this task take into consideration long dependencies only. The proposed method is a two-stage deep neural network model. We start by discovering local dependencies and creating high-level features from word embedding inputs using a deep convolutional neural network. Then we identify long dependencies using a bi-directional recurrent neural network. To solve the problem of unbalanced dataset given by the BMEWO tagging schema and to enforce sequence modeling, we developed a new POS-based tagging schema that subdivides the dominant class into smaller more balanced units. The proposed system was trained and tested on NCBI and achieved an [Formula: see text]-score of 85.59 outperforming the current state-of-the-art methods. Our research results show the effectiveness of using both long and short dependencies. The results also illustrate the benefits of combining different word embedding techniques and the incorporation of morphological features in this task. <\/jats:p>","DOI":"10.1142\/s0219720020500158","type":"journal-article","created":{"date-parts":[[2020,2,24]],"date-time":"2020-02-24T13:36:51Z","timestamp":1582551411000},"page":"2050015","source":"Crossref","is-referenced-by-count":5,"title":["Disease named entity recognition using long\u2013short dependencies"],"prefix":"10.1142","volume":"18","author":[{"given":"Houssemeddine","family":"Derbel","sequence":"first","affiliation":[{"name":"RIADI Laboratory, National School of Computer Science (ENSI), University of Manouba, Manouba University Campus, Manouba 2010, Tunisia"}]},{"given":"Anja Habacha","family":"Chaibi","sequence":"additional","affiliation":[{"name":"RIADI Laboratory, National School of Computer Science (ENSI), University of Manouba, Manouba University Campus, Manouba 2010, Tunisia"}]},{"given":"Henda Hajjami","family":"Ben Ghezala","sequence":"additional","affiliation":[{"name":"RIADI Laboratory, National School of Computer Science (ENSI), University of Manouba, Manouba University Campus, Manouba 2010, Tunisia"}]}],"member":"219","published-online":{"date-parts":[[2020,6,5]]},"reference":[{"key":"S0219720020500158BIB001","doi-asserted-by":"publisher","DOI":"10.1142\/S0219720010005014"},{"key":"S0219720020500158BIB002","doi-asserted-by":"publisher","DOI":"10.1142\/S0219720010004586"},{"key":"S0219720020500158BIB003","doi-asserted-by":"publisher","DOI":"10.2196\/jmir.3331"},{"key":"S0219720020500158BIB004","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0173671"},{"key":"S0219720020500158BIB005","first-page":"82","volume-title":"Proc 2009 Symp Lang Biol Med","volume":"82","author":"Leaman R","year":"2009"},{"key":"S0219720020500158BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2010.08.009"},{"key":"S0219720020500158BIB007","doi-asserted-by":"publisher","DOI":"10.1093\/database\/bar065"},{"key":"S0219720020500158BIB008","doi-asserted-by":"publisher","DOI":"10.1002\/humu.21466"},{"key":"S0219720020500158BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2019.2927253"},{"key":"S0219720020500158BIB011","first-page":"282","volume-title":"Proc.
