syntactic structure obtained by the parsing procedure with semantics by applying some<br />

sort of thematic relations assignment procedure. Parsers are usually based on a particular<br />

linguistic theory, very often on Head Driven Phrase Structure Grammar (Pollard & Sag,<br />

1994) due to the incorporation and making use of notions taken from computer science<br />

(e.g. ‘knowledge representation’, a notion that is needed <strong>for</strong> processing and classification<br />

of data in an in<strong>for</strong>mation system; it is important <strong>for</strong> determining which aspect of data<br />

should be taken into account; <strong>for</strong> example, in a series 31, 28, 31, 30, 31 one knows what<br />

these data represent only if one knows that these are the numbers of days in the first five<br />

months in a year). Parsers do not entirely rely only on grammatical in<strong>for</strong>mation and are<br />

usually in some aspect statistical – <strong>for</strong> example, they employ big corpora <strong>for</strong> training - or<br />

probabilistic rules to determine what aspect of meaning should be taken from the lexicon.<br />

In the broader sense language comprehension includes building a reconstruction of the<br />

state of affairs described in the sentence (or sentences) where linguistic message is<br />

viewed as a set of instructions to achieve this goal. Sometimes in the latter sense a term<br />

sentence understanding is used (Garman, 1990) and it includes not only understanding of<br />

the individual parts of the linguistic message, but<br />

‘…takes account of general knowledge about the events and incorporates<br />

elements that were not actually specified in the linguistic message (Garman, 1990:<br />

305).<br />

This account of sentence comprehension leads to the mental models or situation models<br />

of sentence comprehension (Johnson-Laird, 1983, 1989, van Dijk & Kintsch, 1983,<br />

Zwaan & Radvansky, 1998). This approach is psychologically more realistic and could<br />
