RUSSE'2018: Human-Annotated Sense-Disambiguated Word Contexts for Russian

This dataset contains human-annotated sense identifiers for 2562 contexts of 20 words used in the RUSSE'2018 shared task on Word Sense Induction and Disambiguation for the Russian language; part of the bts-rnc evaluation dataset. These sense identifiers are disambiguated as according to the sense inventory of the Large Explanatory Dictionary of Russian.

The annotation is done on December 1, 2017, on the Yandex.Toloka crowdsourcing platform. In particular, 80 pre-annotated contexts are used for training the human annotators, 2562 contexts are annotated by humans such that each context was annotated by 9 different annotators. The annotation reliability is indicated by a high value of Krippendorff's α = 0.83. After the annotation, every context was additionally inspected (“curated”) by the organizers of the shared task.

The following words are represented: акция (action / stock), байка (yarn / tale), гвоздика (carnation / nail), гипербола (hyperbole), град (avalanche), гусеница (grub), домино (domino), кабачок (marrow / pub), капот (hood), карьер (mine / career), кок (cook), крона (top / crown), круп (croup), мандарин (mandarine), рок (fate / rock), слог (syllable), стопка (glass, stack), таз (bowl), такса (rate / badger-dog), шах (shah / check).
