A proposal for the inductive categorisation of parenthetical discourse markers in Spanish using parallel corpora
We propose a method for the automatic induction of categories of Spanish discourse markers using parallel corpora, based on a quantitative and empirical approach that minimises explicit linguistic knowledge. We conducted the analysis the using a large Spanish-English parallel corpus. First, we used this corpus to obtain a list of parenthetical discourse markers in each language. Then, we used it as a “semantic mirror”, inspecting the English equi…
New verbs and dictionaries
The appearance of new verbs can be observed regularly, but verbs are not frequently investigated in neology, and they are difficult to detect automatically. In this study, a corpus-based method is proposed to detect Spanish verbs with a series of algorithms that analyse the morphology of regular verbs. The vocabulary was drawn from a large corpus and contrasted with a major dictionary of Spanish. Then, a series of filters were applied to distingu…
Corpus-Based Methods for Recognizing the Gender of Anthroponyms
This paper presents a series of methods for automatically determining the gender of proper names, based on their co-occurrence with words and grammatical features in a large corpus. Although the results obtained were for Spanish given names, the method presented here can be easily replicated and used for names in other languages. Most methods reported in the literature use pre-existing lists of first names that require costly manual processing an…

Distributional analysis applied to terminology extraction
This paper presents the first results of a new method for terminology extraction based on distributional analysis. The intuition behind the algorithm is that single or multi-word lexical units that refer to specialised concepts will show a characteristic co-occurrence pattern, described as a tendency to appear in the same contexts with other conceptually related terms. E.g. the term fluoxetine will systematically appear in the same sentences with…
Automatic taxonomy extraction for specialized domains using distributional semantics
This article explores a statistical, language-independent methodology for the construction of taxonomies of specialized domains from noisy corpora. In contrast to proposals that exploit linguistic information by searching for lexico-syntactic patterns that tend to express the hypernymy relation, our methodology relies entirely upon the distributional semantics of terms as captured by their lexical co-occurrence in large scale corpora. In a first …
