The entire case grammar experiment has also been described in detail and with a specific focus on the linguistic relevance of the experiments by van Trijp (2008a).
In this paper I have presented experiments on artificial language evolution that investigated how a population of artificial agents could self-organize a case grammar for marking event structure.
Analogy and multi-level selection in the formation of a Case Grammar.
This case grammar
is used to detect the agent, object and recepient in the sentence which is obtained by analysing the words with repesct to grammar of that language.
This proposal is based on the argumentation theory, in the valence grammar and in the case grammar
In the 1960s, Case Grammar
attempted to develop a functional sense of the parts of speech, substituting, for instance, subject with the more descriptive agent (Williams 120).
He uses linguistic ideas such as case grammar
and transitivity analysis, but extends this work beyond specific sentences to an exploration of the predominant (and often shifting) roles and relations of participants in whole stories.
The techniques explored in the semantic phase of this work include the use of a case grammar
and frames (Schank & Abelson, 1977; Schank & Riesbeck, 1981) to map the surface structure of the text into an internal representation from which the RIFs can be formed.
The semantic representation that we use is a case frame representation based on a variation of case grammar
which was originally introduced in [11, 12].
