It locates in the previous sentenc es the referent or antecedent which the pronoun replaces. An example of a direct anaphora solved is the pronoun he in the sentence He is sad. Much of the work on anaphora has been done for texts in English; thus , we specifically focus on Spanish documents. AnaPro directly supports text analys is (to understand what a document says ), a non trivial task since there are different writing styles, references, idiomatic expressions, etc. The problem grows if t he analyzer is a computer, because they lack common sense (which persons possess) . Hence, before text analysis, its preprocessing is required, in order to assign tags (noun, verb,...) to each word, find the stems, disambiguate nouns, verbs, prepositions, identify colloquial expressions, i dentify and resolve anaphor a, among other chores. AnaPro works for Spanish sentences. It is a novel procedure, since it is automatic (no user intervenes during the resolution) and it does not need dictionaries. It employs heu ristics procedures to discover the semantics and help in the decisions; they are rather easy to implement and use li mited knowledge. Nevertheless, its results are good (81% of correct answers, at least). However, more tests will give a better idea of its goodness. | URI: | http://ri.uaemex.mx/handle20.500.11799/39315 | Other Identifiers: | http://hdl.handle.net/20.500.11799/39315 | Rights: | info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
