    While research on English opinion mining has already achieved significant progress and success, work on Arabic opinion mining is still lagging. This is mainly due to the relative recency of research efforts in developing natural language processing (NLP) methods for Ar...

    We propose a coreference annotation scheme as a layer on top of the Universal Conceptual Cognitive Annotation foundational layer, treating units in predicate-argument structure as a basis for entity and event mentions. We argue that this allows coreference annotators to...

    In this paper, we introduce a general iterative human-machine collaborative method for training crowdsource workers: the classifier (i.e., the machine) selects the highest quality examples for training the crowdsource workers (i.e., the humans). Then, the latter annotat...

    We studied thin films (25 µm-thick) of nanomaterials composed from 3 wt.% aerosil nanospheres and the room-temperature nematic liquid crystal 4-n-heptyl cyanobiphenyl (7CB). The inclusion of 3 wt.% of the photoactive liquid crystal 4-(4'-ethoxyphenylazo)phenyl hexanoate...

    When the European Union began to finance transport and pipeline infrastructure constructions in Bulgaria, large-scale development-led archaeological projects emerged. After 2011, many 'polluter pays' projects were executed with the outlined workflow containing prelimina...

    Tree kernels (TKs) and neural networks are two effective approaches for automatic feature engineering. In this paper, we combine them by modeling context word similarity in semantic TKs. This way, the latter can operate subtree matching by applying neural-based similari...

    Abstract Using lidar and contact facilities, the relation is investigated experimentally between the extinction coefficient and the mass concentration of near-ground aerosol pollution over some districts in Sofia City. The extinction coefficient profiles of the aerosol ...

    Abstract A large-scale massive transport of Saharan dust over all of Europe was observed in the last third of April 2019. As part of the European Aerosol Research Lidar Network (EARLINET) and the Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS), Sofia li...

    Many unsupervised learning techniques have been proposed to obtain meaningful representations of words from text. In this study, we evaluate these various techniques when used to generate Arabic word embeddings. We first build a benchmark for the Arabic language that ca...
