Spoken Language Systems at Saarland University (LSV) participated this year with 5 runs at the TAC KBP English slot filling track. Effective algorithms for all parts of the pipeline, from document retrieval to relation prediction and response post-processing, are bundled in a modular end-to-end relation extraction system called RelationFactory. The main run(More)
In recent years, sedating antidepressants have been increasingly used to treat primary insomnia. Up to now, only one open pilot study with trimipramine and one double-blind placebo-controlled study with doxepin have provided scientific support for this approach in treating primary insomnia. In order to test the hypothesis that sedating antidepressants are(More)
This double-blind, placebo-controlled clinical trial of yohimbine hydrochloride included 86 patients with erectile dysfunction and without clearly detectable organic or psychologic causes. The patient group fulfilled all entry criteria; 85 of these could be considered for the Safety-respectively 83 for the Intention-to-treat (ITT)-analysis. Yohimbine was(More)
In order to evaluate the impact of aging on EEG sleep patterns we investigated the polysomnograms of 74 patients with major depression and 51 healthy volunteers aged 18-65 years. In most of the EEG sleep parameters, age-related changes were obvious in both the depressives and the normals. In the patients, some of these alterations occurred earlier and were(More)
In 30 depressed patients who had responded to total sleep deprivation therapy, morning naps led more frequently to relapses into depression than did afternoon naps. Longer naps were less detrimental than shorter ones, and there was no significant relationship between the effect of a nap on mood and its content of slow-wave-sleep. The amount of the rapid(More)
We survey recent approaches to noise reduction in distant supervision learning for relation extraction. We group them according to the principles they are based on: at-least-one constraints, topic-based models, or pattern correlations. Besides describing them, we illustrate the fundamental differences and attempt to give an outlook to potentially fruitful(More)
We compare several different corpus-based and lexicon-based methods for the scalar ordering of adjectives. Among them, we examine for the first time a low-resource approach based on distinctive-collexeme analysis that just requires a small predefined set of adverbial modi-fiers. While previous work on adjective intensity mostly assumes one single scale for(More)
Total sleep deprivation (TSD) exerts beneficial but transient effects on mood in approximately 60% of patients with a major depressive disorder. The positive effects of a night of total sleep deprivation are generally reversed after the next night of sleep. Several anecdotal reports and a pilot study by our group indicated that even short naps during the(More)
In the treatment of primary insomnia, benzodiazepines and non-benzodiazepine hypnotics are not a first-line medication, mainly due to the dependency risk, especially in longterm treatment. Sedating antidepressants are widely used as an alternative treatment (Wiegand 1999). However, these compounds have several side effects and tend to interact with other(More)
