 To conclude this section, we will briefly mention some contemporary approaches to word meaning that, in different ways, pursue the theoretical agenda of the relational current of the structuralist paradigm. For pedagogical convenience, we can group them into two categories. On the one hand, we have network approaches, which formalize knowledge of word meaning within models where the lexicon is seen as a structured system of entries interconnected by sense relations such as synonymy, antonymy, and meronymy. On the other, we have statistical approaches, whose primary aim is to investigate the patterns of co-occurrence among words in linguistic corpora.
