“…Although coreference resolution in English texts was the main focus of the sixth and seventh Message Understanding Conferences [3, 5], studies of coreference resolution in languages other than English were published in this period, including Japanese [6], Spanish [7], French [8] or Portuguese [9]. A new trend towards multilinguality in the field was established by [10] or [11].…”

This paper describes the process of adapting the Stanford Coreference resolution module to the Basque language, taking into account the characteristics of the language. The module has been integrated in a linguistic analysis pipeline obtaining an end-to-end coreference resolution system for the Basque language. The adaptation process explained can benefit and facilitate other languages with similar characteristics in the implementation of their coreference resolution systems. During the experimentation phase, we have demonstrated that language-specific features have a noteworthy effect on coreference resolution, obtaining a gain in CoNLL score of 7.07 with respect to the baseline system. We have also analysed the effect that preprocessing has in coreference resolution, comparing the results obtained with automatic mentions versus gold mentions. When gold mentions are provided, the results increase 11.5 points in CoNLL score in comparison with results obtained when automatic mentions are used. The contribution of each sieve is analysed concluding that morphology is essential for agglutinative languages to obtain good performance in coreference resolution. Finally, an error analysis of the coreference resolution system is presented which have revealed our system’s weak points and help to determine the improvements of the system. As a result of the error analysis, we have enriched the Basque coreference resolution adding new two sieves, obtaining an improvement of 0.24 points in CoNLL F1 when automatic mentions are used and of 0.39 points when the gold mentions are provided.

When people tend to refer to a previous mentioned discourse entity, they can use various types of anaphoric expressions, such as pronouns, definite noun phrases, proper names or expressions that are introduced by a lexical modifier or a comparative adjective. Among the different types of anaphoric expressions, pronoun is most common and frequently used which contains only a little information about the referent, while definite expressions contain much richer semantic information. As pronouns contain very little information on their own, they are always ambiguous. The cognitive mechanism that underlies the comprehension of pronouns, especially the ones with ambiguities, catches the interests of many researchers. Various tasks have been used to investigate this issue and the results did not go for the same direction. A combination of multiple research methods is needed for a better and deeper understanding of anaphora.

Pronominal anaphors are commonly observed in written texts. In this article, effective Chinese pronominal anaphora resolution is addressed by using lexical knowledge acquisition and salience measurement. The lexical knowledge acquisition is aimed to extract more semantic features, such as gender, number, and collocate compatibility by employing multiple resources. The presented salience measurement is based on entropybased weighting on selecting antecedent candidates.The resolution is justified with a real corpus and compared with a rule-based model. Experimental results by five-fold cross-validation show that our approach yields 82.5% success rate on 1343 anaphoric instances. In comparison with a general rule-based approach, the performance is improved by 7%.
