Well,
now I post material about Systemic Functional Linguistics. Actually I don’t
really understand what the material about but I’ll try to resume it from
resources. Check it out.
SYSTEMIC
FUNCTIONAL LINGUISTICS
Introduction
Systemic, or Systemic-Functional,
theory has its origins in the main intellectual tradition of European
linguistics that developed following the work of Saussure. It is functional and
semantic rather than formal and syntactic in orientation, takes the text rather
than the sentence as its object, and defines its scope by reference to usage
rather than grammaticality.
In systemic theory the system takes
priority; the most abstract representation at any level is in paradigmatic
terms. Syntagmatic organization is interpreted as the REALIZATION of
paradigmatic features.
Systemic-Functional Linguistics
(SFL) is a theory of language centred around the notion of language function.
While SFL accounts for the syntactic structure of language, it places the
function of language as central (what language does, and how it does it), in
preference to more structural approaches, which place the elements of language
and their combinations as central. SFL starts at social context, and looks at
how language both acts upon, and is constrained by, this social context.
A central notion is 'stratification',
such that language is analyzed in terms of four strata: Context, Semantics,
Lexico-Grammar and Phonology-Graphology.
Context concerns the Field (what is
going on), Tenor (the social roles and relationships between the participants),
and the Mode (aspects of the channel of communication, e.g.,
monologic/dialogic, spoken/written, +/- visual-contact, etc.).
Systemic semantics includes what is
usually called 'pragmatics'. Semantics is divided into three components:
- Ideational Semantics (the propositional content);
- Interpersonal Semantics (concerned with speech-function, exchange structure, expression of attitude, etc.);
- Textual Semantics (how the text is structured as a message, e.g., theme-structure, given/new, rhetorical structure etc.
The
Lexico-Grammar concerns the syntactic organization of words into utterances.
Even here, a functional approach is taken, involving analysis of the utterance
in terms of roles such as Actor, Agent/Medium, Theme, Mood, etc.
History of Systemic
SFL grew out of the work of JR
Firth, a British linguist of the 30s, 40s, and 50s, but was mainly developed by
his student MAK Halliday. He developed the theory in the early sixties (seminal
paper, Halliday 1961), based in England, and moved to Australia in the
Seventies, establishing the department of linguistics at the University of
Sydney. Through his teaching there, SFL has spread to a number of institutions
throughout Australia, and around the world. Australian Systemics is especially
influential in areas of language education.
Child Language Development
Some
of Halliday's early work involved the study of his son's developing language
abilities. This study in fact has had a substantial influence on the present
systemic model of adult language, particularly in regard to the metafunctions.
This work has been followed by other child language development work,
especially that of Clare Painter. Ruqaia Hasan has also performed studies of
interactions between children and mothers.
Systemic and Computation
SFL
has been prominent in computational linguistics, especially in Natural Language
Generation (NLG). Penman, an NLG system started at Information Sciences
Institute in 1980, is one of the three main such systems, and has influenced
much of the work in the field. John Bateman (currently in Bremen, Germany) has
extended this system into a multilingual text generator, KPML.
Robin Fawcett in Cardiff have developed another systemic generator, called Genesys.
Mick O'Donnell has developed yet another system, called WAG.
Numerous other systems have been built using Systemic grammar, either in whole
or in part.
One of the earliest and
best-known parsing systems is Winograd's SHRDLU, which uses system networks and
grammar as a central component. Since then, several systems have been developed
using SFL (e.g., Kasper, O'Donnell, O'Donoghue, Cummings, Weerasinghe),
although this work hasn't been as central to the field as that in NLG.
Communication Planes
From the perspective of Systemic
Functional Linguistics the oral and written texts we engage with and produce
have their particular linguistic form because of the social purposes they
fulfill. The focus is not on texts as decontextualized structural entities in
their own right but rather on the mutually predictive relationships between
texts and the social practices they realize.
Level of Social Context
•
The form of human language is as it is
since it co-evolves with the meanings which co-evolve with the community's
contexts of social interaction (Hasan, 1992:24).
•
SFL then, treats language and social
context as complementary levels of semiosis, related by the concept of realisation.
The relationship between language and social context has been represented using
the image of co-tangential circles as in Figure 4.1 (Halliday and Martin,
1993:25).
•
The interpretation of social context
then includes two communication planes, genre (context of culture) and register
(context of situation) (Martin,1992:495).
The context of culture can be thought of as deriving
from a vast complex network of all of the genres which make up a particular
culture. Genres are staged, goal oriented social processes in which people
engage as members of the culture. These genres include all of those routines
from everyday experience such as purchase of goods (food, clothing etc),
medical consultation, eating in a restaurant etc to the genres of particular
forms of social life including church services, TV interviews, getting arrested
etc.
•
The FIELD OF DISCOURSE refers to what is
happening, to the nature of the social action that is taking place: what is it
that the participants are engaged in, in which the language figures as some
essential component?

Information:
•
Semantics is
the interface between language and context of situation (register). Semantics
is therefore concerned with the meanings that are involved with the three
situational variables Field, Tenor and Mode. Ideational meanings realise Field,
interpersonal meanings realise Tenor and textual meanings realise Mode.
•
Lexicogrammar
is a resource for wording meanings, ie. realising them as configurations of
lexical and grammatical items. It follows then, that lexicogrammar is characterised
by the same kind of metafunctional diversification discussed above. This takes
us back to our discussion in section three where we showed that functional
grammar included three separate analyses, each describing the construction of
one of three different kinds of meaning which all operate simultaneously in
each clause.
•
Ideational
(experiential and logical) meanings construing Field are realised lexicogrammatically
by the system of Transitivity. This system interprets and represents our
experience of phenomena in the world and in our consciousness by modelling experiential
meanings in terms of participants, processes and circumstances. Resources for
chaining clauses into clause complexes, and for serialising time by means of
tense, address logical meanings.
•
Interpersonal meanings are realized lexicogrammatically
by systems of Mood and Modality and by the selection of attitudinal lexis. The
Mood system is the central resource establishing and maintaining an ongoing
exchange between interactants by assuming and assigning speech roles such as
giving or demanding goods and services or information.
