The increased volumes of Arabic sources of data available on the Web has boosted the development of Natural Language Processing (NLP) tools over different tasks and applications. However, to take advantage from a vast amount of these applications, a prior segmentation task call Sentence Boundary Detection (SBD) is needed. In this paper we focus on SBD over Modern Standard Arabic (MSA) by comparing two different approaches based on Deep Neural Networks (DNN) using out-of-domain and in-domain training data with only lexical features (represented as character embedding) while conducting two scenarios based on a Convolutional Neural Network and a Recurrent Neural Network with attention mechanism architectures. While tuning a big out-of-domain dataset with a smaller in-domain dataset, improves the performance in general. Our evaluations were based on IWSLT 2017 TED talks transcripts and showed similarities and differences depending of the SBD method. MSA carries certain complications given its rich and complex morphology. However, using only lexical features for Arabic SBD is an acceptable option when the source audio signal is not available and a certain level of language independence needs to be reached.
