Abstract

This paper presents a computerized grammar which can analyze and generate a sample of pedagogical Chinese sentences, in particular those mentioned in the textbook Kinesiska är inte svårt (‘Chinese is not difficult’) by Göran Malmqvist 1974. Equivalent grammars for English and Swedish have also been constructed allowing translation between the three languages. The grammar model used is the Swetra grammar developed in the MT-project Swetra at the Department of Linguistics, Lund University and used in various translation and generation projects, including the application which generates weather reports in Swedish and English used by SMHI, the Swedish meteorological agency. The Swetra grammar (see Sigurd (ed.) 1994) is written directly in the DCG (Definite Clause Grammar) format and implemented in Prolog (LPAProlog). It has been used for several languages and adapted to various practical needs. Swetra grammar is characterized by its separate functional (-semantic) representation which is abstract enough to be used as an interlingua in automatic translation. The functional representation of Swetra does not show surface details such as word order, case or agreement. Swetra grammar has ways to account for mode, topic, coordinated clauses and subordinate clauses including relative clauses. The word meanings are represented by a standardized English Machinese according to certain conventions. The construction of a computerized grammar of Chinese can be based on traditional Chinese grammar but it requires reconsideration and taking a number of decisions. The computerized grammars presented pinpoint the differences between Chinese, English and Swedish. The Chinese, English and Swedish grammars and lexicons are constructed to enable the automatic translation into or from these languages using the Swetra functional representation as interlingua. In order to allow writing in both Chinese characters and pinyin the lexical items of the grammar are rended in these two systems. Demo sentences showing the use of the Chinese, English and Swedish grammars are presented.
