Error analysis for anaphora resolution in Russian: new challenging issues for anaphora resolution task in a morphologically rich language

Abstract: This paper presents a quantitative and qualitative error analysis of Russian anaphora resolvers which participated in the RU-EVAL event. Its aim is to identify and characterize a set of challenging errors common to stateof-the-art systems dealing with Russian. We examined three types of pronouns: 3rd person pronouns, reflexive and relative pronouns. The investigation has shown that a high level of grammatical ambiguity, specific features of reflexive pronouns, free word order and special cases of non-referenti… Show more

“…Mixed Polish coreferences resolution approach combines neural networks architecture with the sieve-based approach [48]. For Russian, RU-EVAL-2014 [49] was an evaluation campaign of anaphora and coreferences resolution tools that employed a wide variety of approaches. The evaluation was performed on Russian Coreference Corpus (RuCur).…”
