Özetçe-Bir sınıfa ait bir metni başka bir sınıfa ait metinden hangi özellikleri ayırt eder? Bu soruya çeşitli cevaplarvererek metin dosyalarının otomatik sınıflandırılması için uzun zamandır çalışmalar sürmektedir. Bu çalışmada Türkçe metinlerin özelliklerinin çıkarılması işlemini yapan Text2arff yazılımına eklenen yeni özellikler (word2vec, metin yörüngeleri vb.) tanıtılmıştır. Yazılım başka uygulamalardan çağrılabilecek bir kütüphane haline getirilmiştir. İki örnek veri kümesi üzerinde yazılım denenmesiyle elde edilen sonuçlarına göre farklı metin temsil yöntemlerinin kullanımının etkisi farklı sınıflandırıcı kullanımının etkisinden çok daha fazla olduğudur. Bu da metin sınıflandırmada yeni metin temsil yöntemleri üzerine çalışmanın önemini ortaya koymaktadır.

In the automatic text categorization area, several studies seek answers to this question. In this paper, new version of Text2arff (a library for text representation) and its new features (word2vec, Word trajectories, etc.) are presented. Also, the software is now a java library which can be used in the user's own projects. In the experiments, the library is run on two sample datasets. The results show that the effect of text representation method is bigger than the classification method. This result also emphasizes the importance of developing new test representation methods.
SUMMARY: Kamit-Can F, Alparslan C, Anıl AB, Anıl M, Zengin N, Can E. The need for mechanical ventilation in a child exposed to a laundry detergent pod. Turk J Pediatr 2016; 58: 323-326.Laundry detergent pods (LDPs) are a new, concentrated form of detergent covered by a membrane of polyvinyl alcohol or other water-soluble material. In contrast to traditional laundry detergents, the spectrum of responses to exposure to LDPs ranges from mild to life-threatening events. This is a case report of a 3-year-old male who ingested part of an LDP, leading to a depressed level of consciousness, upper airway obstruction, and severe respiratory distress. The patient required intubation and mechanical ventilation for 2 days before being discharged. This rare, severe clinical pattern demonstrates the potential toxicity of these laundry detergents. In the literature, few cases that required intubation and ventilation have been reported. To our knowledge, this is also the first case of LDP exposure reported from Turkey.
