Neural Natural Language Processing for Long Texts: A Survey of the State-of-the-Art
The adoption of Deep Neural Networks (DNNs) has greatly benefited Natural
Language Processing (NLP) during the past decade. However, the demands of long
document analysis are quite different from those of shorter texts, while the
ever increasing size of documents uploaded on-line renders automated
understanding of long texts a critical area of research. This article has two
goals: a) it overviews the relevant neural building blocks, thus serving as a
short tutorial, and b) it surveys the state-of-the-art in long document NLP,
mainly focusing on two central tasks: document classification and document
summarization. Sentiment analysis for long texts is also covered, since it is
typically treated as a particular case of document classification.
Additionally, this article discusses the main challenges, issues and current
solutions related to long document NLP. Finally, the relevant, publicly
available, annotated datasets are presented, in order to facilitate further
research.Comment: 53 pages, 2 figures, 171 citation
Hepatic Abscess 6 years after ERCP
Backround : ERCP combined with the insertion of biliary endoprosthesis is considered a daily practice endoscopic intervention for the treatment of choledocholithiasis. Nevertheless, retained biliary stents for a prolonged period without follow up may cause serious complications. Case presentation : We present the case of a 62-year-old man who was hospitalized with symptoms of vomiting, abdominal pain, fatigue and fever. Clinical examination and laboratory results were indicative of an intra abdominal infection. Ultrasound and CT scans were performed, identifying a 17x11.3x7.7 cm. The cause of this lesion was a retained stent in the common bile duct which was placed 6 years ago via endoscopic retrograde cholangiopancreatography. The patient did not attend his follow up appointments after his initial ERCP. Patient’s clinical status deteriorated, and an urgent ERCP was performed replacing the retained stent, followed by ultrasound-guided pigtail stent insertion into the hepatic abscess and administration of antibiotics intravenously. Patient’s clinical condition was improved and after two months of surveillance complete resolution of the hepatic abscess was achieved. Conclusion : The insertion of biliary stents is common endoscopic technique, but close follow up is of outmost importance
