We propose a method to quantify semantic linguistic maturity (SELMA) based on a high dimensional semantic representation of words created from the co-occurrence of words in a large text corpus. The SELMA method was applied to oral narratives from 108 children aged 4;0-12;10. By comparing the SELMA measure with maturity ratings made by human raters we found that SELMA predicted the rating of semantic maturity made by human raters over and above the prediction made using a child's age and number of words produced. We conclude that the semantic content of narratives changes in a predictable pattern with children's age and argue that SELMA is a measure quantifying semantic linguistic maturity. The study opens up the possibility of using quantitative measures for studying the development of semantic representation in children's narratives, and emphasizes the importance of word co-occurrences for understanding the development of meaning.

This study has two goals: First, to give an account of the semantic organization of individually used antonymic adjectives in discourse and second, based on those findings and previous work on antonymic meanings, to contribute to a comprehensive theoretical account of their representation within the framework of Cognitive Linguistics. The hypothesis is that the members of the pairs are used in the same contexts and in the same type of constructions, not only when they co-occur and are used to express binary opposition as shown in previous studies, but also when they do not. The manually coded corpus data from the BNC are analyzed along four semantic parameters: (i) the configuration of the adjectives in terms of gradability, (ii) the way they modify the nominal meanings, i.e., attributively or predicatively (iii) the meaning type of the modified nouns, and (iv) the status of the constructions with respect to whether their meanings are what we refer to as "basic", metaphorical or metonymical. Correspondence analysis technique is used to identify similarities and differences on the basis of the totality of the data. As predicted, our findings confirm a high degree of pairwise similarity -but also some differences. On the basis of these results, it can be argued that the long-standing controversy within Structuralism between proponents of the co-occurrence hypothesis and the substitutability hypothesis in antonym research is a non-issue.Keywords: opposition, gradability, nominal meaning, metaphor, metonymy, literal, scalar, corpus, adjectives, English, semantics, noun, attributive, figurative, syntagmatic, paradigmatic, substitution hypothesis, co-occurrence hypothesis

Within cognitive linguistics, the notion of domain is central. In the literature, the notion of domain has been interpreted in an all-encompassing way, which has led to conceptual confusion. The article proposes to distinguish between a more psychologically oriented description of domains based on dimensional structures, on the one hand; and meronomic relations, on the other. It is shown how Langacker's notion of a configurational domain can be analyzed as higher-level dimensional structures. An added benefit of the distinction between dimensional domains and meronomic relations is that it generates a natural account of the difference between metaphors and metonymies.
