## Abstract

A translation machine capable of translating a sentence in a source language with an ambiguous parallel disposition of words and/or phrases into an accurate sentence in a target language includes a unit (151) for looking-up dictionaries and for analyzing morphological of the sentence in the source language input to the translation machine so as to provide a part of speech of the analyzed morphological, a unit (152) connected to the dictionary look up and morphological analyzing unit (151) for analyzing a syntactic of the sentence based on the obtained parts of speech of the morphological by using grammatical rules stored in the dictionary look up and morphological analyzing unit (151), a unit (153) connected to the syntactic analyzing unit (152) for transforming the analyzed syntactic into a syntactic in a target language, and a unit (154) connected to the transforming unit (153) for generating a translated sentence in the target language in accordance with the transformed syntactic in the target language.

## Claims

### Claim 1

A translation machine for translating into a target language a sentence including a plurality of words and/or phrases, a word and/or phrase group of a plurality of other words and/or phrases, a parallel-disposition start symbol just before said word and/or phrase group, and a parallel-disposition end symbol, said start symbol including a part-of-speech specifying symbol, said machine comprising:
a first storing means for storing said sentence in a first buffer;
a second storing means for storing sequentially in a second buffer a first information unit including said words and/or phrases and said other words and/or phrases, and the corresponding word locations thereof;
a third storing means for storing in a third buffer a second information unit including said part-of-speech specifying symbol, a word location just after said start symbol, and the number of said other words and/or phrases between said start symbol and said end symbol; and
an adding means for adding said second information stored in said third buffer to said first information stored in said second buffer.

### Claim 2 (depends on 1)

A translation machine according to claim 1, wherein said part-of-speech specifying symbol specifies a part-of-speech of said word and/or phrase group as one of a noun, a verb, an adjective and an adverb, said start symbol indicates a start of said word and/or phrase group, and said end symbol indicates an end of said word and/or phrase group.

### Claim 3 (depends on 2)

A translation machine according to claim 2, wherein said part-of-speech specifying symbol is nS for noun, vS for verb, aS for adjective, and dS for adverb.

### Claim 4 (depends on 3)

A translation machine according to claim 3, wherein said start symbol is nS [ for noun, vS [ for verb, aS [ for adjective, and dS [ for adverb.

### Claim 5 (depends on 4)

A translation machine according to claim 4, wherein said end symbol is E [.

### Claim 6 (depends on 1)

A translation machine according to claim 1, wherein said sentence further includes a parallel element start symbol and a parallel element end symbol.

### Claim 7 (depends on 5)

A translation machine according to claim 5, wherein said parallel element start symbol is [.

### Claim 8 (depends on 5)

A translation machine according to claim 5, wherein said parallel element end symbol is ].
