Remembered frameworks

The field of artificial intelligence (Al) has provided a further approach to how people understand one another. AI makes proposals about how to simulate intelligent systems on computers. The original prob­lem was one of finding out how computers could be made to cope with inexplicit and superficially irrelevant conversations:

Salesman: Pink sinks are the latest fashion, madam. Customer: My dish-washer's red.

A solution proposed for the computer might also be one utilized by humans. Knowledge, it was suggested, might be stored in the form of stereotypical situations, or frames. These memorized frameworks are adapted to fit in with present reality, so they are altered as required. So, for example, a person might have a frame representing a typical kitchen, and would have 'slots' in the frame for a sink, a cooker, a dish-washer and so on. A superficially disjointed conversation, such as the one above, would become quite coherent when considered in relation to the 'kitchen frame' in a person's mind. Furthermore the speakers in this conversation clearly have a certain amount of mutual knowledge, in that they both have a similar outline kitchen frame. Another way of dealing with human interaction, therefore, is to spec­ify both the relevant frames and the mutual knowledge held in com­mon by the participants.

Discourse analysis

So far, we have concentrated on cases in which people made sense of quite strange disjointed utterances. However, when we use language, we do not necessarily do so in a random and unstructured way. Both conversation and written texts have various devices for welding together miscellaneous utterances into a cohesive whole. Compare the two accounts of George's meal below:

A George ate the curry with delight. Curry had always been George's favourite food. The curry was subtly flavoured. George detected hints of cumin and coriander in the curry. Cumin and coriander are George's favourite spices.

В George ate the curry with delight. This type of food had always

been his favourite. The dish was subtly flavoured, ami in it he detected hints of his favourite spices, cumin and coriander.

The two versions are more or less the same as far as semantic con­tent is concerned, and the syntax is fairly similar. Nevertheless, there4 is a lot of difference between the two. The second is both stylistically better, and more normal-sounding. The first appears to have been written sentence by sentence, without any attention to the overall effect. In the second, various devices have been used in order to link the sentences together into a cohesive whole: after its first occur­rence, the word curry has been replaced by alternative words this type of food, the dish, and by the pronoun it. Similarly, George has been replaced by he, and in some places, the order of words has been altered so as to maintain the smooth connections, as when in it was brought to the front of its clause. In addition, some of the original sen­tences have been joined together.

Discourse analysis is the study which deals with this topic. It over­laps with stylistics, the study of linguistics and literature. Devices which maintain the smooth flow of communication are particularly important in written language, where there is no one available to clarify unclear points. However, many of these devices are also used in ordi­nary conversation. Consider two versions of the same dialogue:

A Edna: Someone ought to lock up Fred. Minnie: Fred is a disgrace.

Edna: Someone caught Fred peeping at the new lodger through the bathroom window.

Minnie: What is the name of the new lodger? Is the name of the new lodger Arabella or Annabel?

В Edna: Fred ought to be locked up. Minnie: That man's a disgrace.

Edna: He was caught peeping through the bathroom window at the new lodger.

Minnie: What's her name? Is it Arabella or Annabel?

The first version sounds stilted and odd, even though by itself, each sentence is well-formed. The second version sounds far more like an ordinary conversation. It contains devices similar to those used in the piece of prose about George and his curry: alter the first occurrence of Fred, the alternative phrase that man and the pronoun he was used. 'Hie third sentence has been changed into the passive, in order lo keep Fred at the centre of attention. And so on. The overall result is that the whole

dialogue becomes linked together into a cohesive whole, something that people who know a language do automatically - though people learning a second language usually have to be taught this skill, as the devices used vary in their details from language to language.
