Automatic propbank generation for Turkish

Semantic role labeling (SRL) is an important task for understanding natural languages, where the objective is to analyse propositions expressed by the verb and to identify each word that bears a semantic role. It provides an extensive dataset to enhance NLP applications such as information retrieval, machine translation, information extraction, and question answering. However, creating SRL models are difficult. Even in some languages, it is infeasible to create SRL models that have predicate-argument structure due to lack of linguistic resources. In this paper, we present our method to create an automatic Turkish PropBank by exploiting parallel data from the translated sentences of English PropBank. Experiments show that our method gives promising results. © 2019 Association for Computational Linguistics (ACL).Publisher's Versio

Autologous repair of an internal carotid artery aneurysm by resection, caliber reduction, and external mesh tube reinforcement in a 9-year-old boy

Extracranial internal carotid artery aneurysms in children are rare, with a reported incidence of 0.5% to 1.9% in internal carotid artery aneurysm operations compared with all carotid operations in adult patients. We report a case of surgical reconstruction of an extracranial internal carotid artery aneurysm in a 9-year-old boy. Our patient complained of episodic neck pain on the left site under the mastoid process for the last year. The child was otherwise healthy. Autologous reconstruction without graft interposition was planned. Surgical repair was performed by resection of the main body of the aneurysm and restoration of the arterial continuity with end-to-end anastomosis. Because nondilated proximal and distal vessels could not be approximated, the most distal end of the aneurysm was tapered over a mandril. To prevent redilation, a tubular polyester external stent was fitted around the diseased segment

Construction of a Turkish proposition bank

This paper describes our approach to developing the Turkish PropBank by adopting the semantic role-labeling guidelines of the original PropBank and using the translation of the English Penn-TreeBank as a resource. We discuss the semantic annotation process of the PropBank and language-specific cases for Turkish, the tools we have developed for annotation, and quality control for multiuser annotation. In the current phase of the project, more than 9500 sentences are semantically analyzed and predicate-argument information is extracted for 1330 verbs and 1914 verb senses. Our plan is to annotate 17,000 sentences by the end of 2017.This work was supported by Isik University BAP projects 14B206 and 15B201Publisher's Versio

Ameloblastic Fibroma: a Case Report With Five Years Follow-Up

Svrha ovog rada bila je opisati rijedak slučaj dugo praćenoga ameloblastičnog fibroma (AF-a) na atipičnoj lokalizaciji. Ameloblastični fibrom dosta je rijedak benigni miješani odontogeni tumor koji se vrlo rijetko može naći u prednjoj regiji gornje čeljusti. Čini samo 1 do 2 posto svih odontogenih tumora i češći je kod muškaraca negoli kod žena. Češći je u donjoj čeljusti negoli u gornjoj. Većina ameloblastičnih fibroma nalazi se u stražnjem području donje čeljusti, bezbolni su, sporo rastu i uglavnom su asimptomatski, ali mogu proširiti čeljust. Prikaz slučaja: trogodišnja djevojčica bila se žalila na bezbolnu oteklinu u području desne gornje čeljusti. Radiološka pretraga pokazala je dobro ograničenu, veliku leziju. Prema histopatološkim nalazima, dijagnosticirana je kao ameloblastični fibrom. Liječena je enukleacijom te nije bio uočen recidiv na kontrolnom pregledu nakon pet godina. Nakon toga razdoblja radiološke snimke pokazale su da se kirurški defekt ispunio novom kosti. Konzervativni pristup, uključujući enukleaciju i mehaničku kiretažu okolnog tkiva, pokazao se uspješnim za pacijenta. Iako je recidiv ameloblastičnog fibroma rijedak, redoviti pregledi – kako bi se pratio rast i razvoj - potrebni su zbog velike mogućnosti recidiva.The purpose of this article is to describe a rare case of Ameloblastic Fibroma (AF) with atypical localization with long term follow-up period. The AF is a relatively rare benign mixed odontogenic tumour, which is extremely uncommon in the anterior maxillary region. It represents only 1-2% of all odontogenic tumors and males are slightly more frequently affected than females. It presents more frequently in the mandible than maxilla. The majority of AF’s are found in the posterior area of the mandible and painless, slow growing and usually asymptomatic but eventually expand the jaw. A 3 year-old girl with a chief complaint of painless swelling on the right maxillar area. Radiological evaluation revealed a well-circumscribed large lesion. The lesion was diagnosed as AF according to the histopathological fi ndings. She was treated by enucleation with no recurrence observed after a follow-up period of 5 years. After fi ve years, radiographs showed that the surgical defect had fi lled with new bone. A conservative approach, including enucleation and mechanical curettage of the surrounding tissue appeared to be successful for the patient. Although recurrence of AF is rare, regular reviews to monitor growth and development are required for the high potential of recurrence rates

Clinical features and molecular genetic analysis in a Turkish family with oral white sponge nevus

Oral white sponge nevus (WSN) is a rare autosomal dominant benign condition, characterized by asymptomatic spongy white plaques. Mutations in Keratin 4 (KRT4) and 13 (KRT13) have been shown to cause WSN. Familial cases are uncommon due to irregular penetrance. Thus, the aim of the study was: a) to demonstrate the clinical and histopathological features of a three-generation Turkish family with oral WSN b) to determine whether KRT4 or KRT13 gene mutation was the molecular basis of WSN. Out of twenty members of the family ten were available for assessment. Venous blood samples from six affected and five unaffected members and 48 healthy controls were obtained for genetic mutational analysis. Polymerase chain reaction was used to amplify all exons within KRT4 and KRT13 genes. These products were sequenced and the data was examined for mutations and polymorphisms. Varying presentation and severity of clinical features were observed. Analysis of the KRT13 gene revealed the sequence variant Y118D as the disease-causing mutation. One patient revealed several previously unreported polymorphisms including a novel mutation in exon 1 of the KRT13 gene and a heterozygous deletion in exon 1 of KRT4. This deletion in the KRT4 gene was found to be a common polymorphism reflecting a high allele frequency of 31.25% in the Turkish population. Oral WSN may manifest variable clinical features. The novel mutation found in the KRT13 gene is believed to add evidence for a mutational hotspot in the mucosal keratins. Molecular genetic analysis is required to establish correct diagnosis and appropriate genetic consultation
