Methods and Systems for Alignment of Parallel Text Corpora

A computer-implemented method of aligning fragments of a first text in a first language with corresponding fragments of a second text, which is a translation of the first text into a second language, comprising:

• preliminarily dividing the first and second texts into fragments;
• generating a hypothesis about correspondence between at least first fragment in the first text and at least second fragment in the second text;
• performing a lexico-morphological analysis of the first and the second fragments using linguistic descriptions;
• performing a syntactic analysis of the first and the second fragments using linguistic descriptions and generating a syntactic structure for the first fragment and a syntactic structure for the second fragment;
• generating a semantic structure for the first fragment and a semantic structure for the second fragment;
• estimating the degree of correspondence between the semantic structure for the first fragment and the semantic structure for the second fragment;
• saving the generated syntactic and semantic structures for the first fragment in connection with the first fragment;
• and
• saving the generated syntactic and semantic structures for the second fragment in connection with the second fragment.

A computer system for aligning fragments of a first text in a first language with corresponding fragments of a second text, which is a translation of the first text into a second language, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory storing instructions, which when executed by the computer system for aligning fragments cause the system to perform a method comprising:
• preliminarily dividing the first and second texts into fragments;
• generating a hypothesis about correspondence between at least first fragment in the first text and at least second fragment in the second text;
• performing a lexico-morphological analysis of the first and the second fragments using linguistic descriptions;
• performing a syntactic analysis of the first and the second fragments using linguistic descriptions and generating a syntactic structure for the first fragment and a syntactic structure for the second fragment;
• generating a semantic structure for the first fragment and a semantic structure for the second fragment;
• estimating the degree of correspondence between the semantic structure for the first fragment and the semantic structure for the second fragment;
• saving the generated syntactic and semantic structures for the first fragment in connection with the first fragment;
• and
• saving the generated syntactic and semantic structures for the second fragment in connection with the second fragment.

A computer-readable medium having stored thereon a sequence of instructions, which, when executed by a computer system for aligning fragments of a first text in a first language with corresponding fragments of a second text, which is a translation of the first text into a second language, causes the system to perform a method, comprising:

• preliminarily dividing the first and second texts into fragments;
• generating a hypothesis about correspondence between at least first fragment in the first text and at least second fragment in the second text;
• performing a lexico-morphological analysis of the first and the second fragments using linguistic descriptions;
• performing a syntactic analysis of the first and the second fragments using linguistic descriptions and generating a syntactic structure for the first fragment and a syntactic structure for the second fragment;
• generating a semantic structure for the first fragment and a semantic structure for the second fragment;
• estimating the degree of correspondence between the semantic structure for the first fragment and the semantic structure for the second fragment;
• saving the generated syntactic and semantic structures for the first fragment in connection with the first fragment;
• and
• saving the generated syntactic and semantic structures for the second fragment in connection with the second fragment.
