We present our submission to SemEval-2015 Task 7: Diachronic Text Evaluation, in which we approach the task of assigning a date to a text as a multi-class classification problem. We extract n-gram features from the text at the letter, word, and syntactic level, and use these to train a classifier on date-labeled training data. We also incorporate date(More)
In this paper we present the system we submitted to the PAN 2015 competition for the author verification task. We consider the task as a supervised classification problem, where each case in a dataset is an instance. Our approach combines the output from multiple learners using basic stacked generalization. The individual learners are obtained using five(More)
Eukaryotic genomes are replicated from many origin sites that are licensed by the loading of the replicative DNA helicase, Mcm2-7. How eukaryotic origin positions are specified remains elusive. Here we show that, contrary to the bacterial paradigm, eukaryotic replication origins are not irrevocably defined by selection of the helicase loading site, but can(More)
There have been no studies specifically examining the efficacy of selective serotonin reuptake inhibitor antidepressants for the symptoms of depression in schizophrenia. This study aimed to determine the efficacy and safety of sertraline as a treatment for depressive symptoms in patients with stable, chronic schizophrenia. The Beck Depression Inventory(More)
Experiments on the detection of the source language of literary translations are described. Two feature types are exploited, n-gram based features and document-level statistics. Cross-validation results on a corpus of twenty 19th-century texts including translations from Russian, French, German and texts written in English are promising: single feature(More)
In 1949 Donald Hebb published The Organization of Behavior, in which he introduced several hypotheses about the neural substrate of learning and memory , including the Hebb learning rule, or Hebb synapse. We now have solid physiological evidence, verified in several laboratories, that long-term potenti-ation (LTP) in some parts of the mammalian hippocampus(More)
This article outlines a simple method for parsing an ASCII-format dramatic work from the Project Gutenberg Corpus into separate characters. The motivation for the program is a upcoming study in computational stylistics and characterization in drama. Various previous approaches involving interactive media are examined and the parser is evaluated by comparing(More)
Research into the stylistic properties of translations is an issue which has received some attention in computational stylistics. Previous work by Rybicki (2006) on the distinguishing of character idiolects in the work of Polish author Henryk Sienkiewicz and two corresponding English translations using Burrow's Delta method concluded that idiolectal(More)
