Paraphrase detection is important for a number of applications, including plagiarism detection, authorship attribution, question answering, text summarization, text mining in general, etc. In this paper, we give a performance overview of various types of corpus-based models, especially deep learning (DL) models, with the task of paraphrase detection. We report the results of eight models (LSI, TF-IDF, Word2Vec, Doc2Vec, GloVe, FastText, ELMO, and USE) evaluated on three different public available corpora: Microsoft Research Paraphrase Corpus, Clough and Stevenson and Webis Crowd Paraphrase Corpus 2011. Through a great number of experiments, we decided on the most appropriate approaches for text pre-processing: hyper-parameters, sub-model selection—where they exist (e.g., Skipgram vs. CBOW), distance measures, and semantic similarity/paraphrase detection threshold. Our findings and those of other researchers who have used deep learning models show that DL models are very competitive with traditional state-of-the-art approaches and have potential that should be further developed.

Computer security, school security policy and school computers usability should be important for all school computers and network resources users. But instead of implementing security policy, users often unintentionally compromise computer functionality and security out of ignorance or negligence. Since Windows is the default operating system in the majority of Croatian schools, students often have to use computers in the role of administrator. Bearing in mind the multitude of new technological solutions and continual changes which happen in this industry, this paper tries to provide an overview of software solutions for IT administrators of school computers, which are also applicable in libraries, colleges, universities and other public places which use computers with Windows OS.
