CsFEVER and CTKFacts: acquiring Czech data for fact verification.

In this paper, we examine several methods of acquiring Czech data for automated fact-checking, which is a task commonly modeled as a classification of textual claim veracity w.r.t. a corpus of trusted ground truths. We attempt to collect sets of data in form of a factual claim, evidence within the ground truth corpus, and its veracity label (supported, refuted or not enough info). As a first attempt, we generate a Czech version of the large-scale FEVER dataset built on top of Wikipedia corpus. We take a hybrid approach of machine translation and document alignment; the approach and the tools we provide can be easily applied to other languages. We discuss its weaknesses, propose a future strategy for their mitigation and publish the 127k resulting translations, as well as a version of such dataset reliably applicable for the Natural Language Inference task-the CsFEVER-NLI. Furthermore, we collect a novel dataset of 3,097 claims, which is annotated using the corpus of 2.2 M articles of Czech News Agency. We present an extended dataset annotation methodology based on the FEVER approach, and, as the underlying corpus is proprietary, we also publish a standalone version of the dataset for the task of Natural Language Inference we call CTKFactsNLI. We analyze both acquired datasets for spurious cues-annotation patterns leading to model overfitting. CTKFacts is further examined for inter-annotator agreement, thoroughly cleaned, and a typology of common annotator errors is extracted. Finally, we provide baseline models for all stages of the fact-checking pipeline and publish the NLI datasets, as well as our annotation platform and other experimental data.

On Gerasimov's plastic facial reconstruction technique: new insights to facilitate repeatability.

Gerasimov's plastic facial reconstruction method is notoriously difficult to repeat from the published literature. Primarily, this is because of the method's underlying qualitative basis but other factors contribute including: misreports in the secondary literature of Gerasimov's method essence; a lack of published details concerning Gerasimov's modeling mastic; Gerasimov's deviation from his own published nose projection prediction guidelines; and continued refinement of the methods in the 15 years following their foremost publication. As Gerasimov cannot be consulted to resolve these issues, we provide solutions via one of his five former principal students. This includes clarification of Gerasimov's method and use of soft tissue depths; the constitution of his modeling mastic; methods used for nose projection prediction; and refinements made to his methods following their primary publication.

[Goethe's skull and skeleton]. / Goethes Schädel und Skelett.

In 1970 there was a conservation of Goethe's skeleton, housed in the Fürstengruft in Weimar. This procedure was kept secret until 1999. The restoration of the sarcophagus and the conservation of the skeleton have been documented together with many photos in the so-called "Sonderakte Mazeration Goethe" (special file mazeration Goethe). In this special file there are also photos of Goethe's skull and skeleton which will be published here for the first time and analysed under anthropological and palaeopathological aspects. A short description of the skull will be given. The dentition of Goethe at the time of his death and the question of progenia in Goethe's family are discussed in detail. Data on Goethe's stature obtained from the skeleton qualify statements of Goethe's contemporaries. Among the few documented pathological changes the ankylosis of eight thoracal vertebrae (T 5-12) and five right ribs are of special interest, caused by the loss of the intervertebral discs, spondylosis deformans and Morbus Forestier. A connection between this ankylosis and the known stiff posture and stiff gait of Goethe is obviously and possibly dates back to Goethe's fortieth years of age.
