Method and system for automatic analysis of legal documents using sequence alignemnt

A system for automatically analyzing legal documents, the system comprising:

• a computer memory that receives a labelled legal document and at least one unlabeled legal document, wherein the legal documents exhibit similarity in terms of table of content thereof, and wherein the labelled legal document is labelled with a plurality of labels each indicating a start point and an end point of predefined entities associated with said legal documents;
• a text conversion module that converts the legal documents to respective sequences of characters;
• a global alignment module that applies a global alignment sequencing process to said sequence of characters of the labelled legal document and the sequence of characters of the at least one unlabeled legal document, based on said labels;
• a labelling transfer module that derives pointers to said start points and end points of the predefined entities in the unlabeled legal document based on said global alignment sequencing process;
• and
• a labeling module that labels the unlabeled legal document using said pointers.

A non-transitory computer readable storage medium for automatically analyzing legal documents, the computer readable storage medium comprising a set of instructions that when executed cause at least one computer processor to:

• receive a labelled legal document and at least one unlabeled legal document, wherein the legal documents exhibit similarity in terms of table of content thereof, and wherein the labelled legal document is labelled with a plurality of labels each indicating a start point and an end point of predefined entities associated with said legal documents;
• convert the legal documents to respective sequences of characters;
• apply a global alignment sequencing process to said sequence of characters of the labelled legal document and the sequence of characters of the at least one unlabeled legal document, based on said labels;
• derive pointers to said start points and end points of the predefined entities in the unlabeled legal document based on said global alignment sequencing process;
• and
• label the unlabeled legal document using said pointers.
