Abstract
Embodiments of the present invention provide systems and methods for extracting and annotating text. Heuristics are applied to extracted text data in order to detect the readability of the text data. The text data is converted to an intermediate form. The transformed intermediate form is converted back to the original text format. Character and feature correspondence; positional logic; and queries to determine if the text data within a line corresponds with a token header are used to maintain the formatting and annotate the original text.
Claims15
A method for extracting and annotating text, the method comprising the steps of:
- performing, by one or more processors, a copying operation on a first source;
- extracting, by one or more processors, text data from the copy operation, wherein the text data comprises a stream of characters in a first text format;
- applying, by one or more processors, heuristics to extracted text data from the first source, wherein the heuristics detect readability of the text data;
- encoding, by one or more processors, the text data into a second text format, wherein encoding the text data into the second text format maintains structures and elements of the text data;
- transforming, by one or more processors, the second text format into annotations with the first text format;
- performing, by one or more processors, a pasting operation on the transformed annotations in the first text format while maintaining a respective arrangement of the structure and elements of the first text format;
- responsive to transforming the second text format into the annotations with the first text format, resolving, by one or more processors, offsets into the first source to maintain a format, structure, and elements of the annotations within a matrix structure;
- applying, by one or more processors, validating analytics on the extracted text data, the annotations with the first text format, and search queries within the matrix structure, wherein the validating analytics comprise at least:
- delimitation and position logic;
- responsive to analyzing the search queries by applying the validation analytics, determining, by one or more processors, if the text data a line corresponds with a token header, wherein the line is contained within the matrix structure;
- determining, by one or more processors, character and feature correspondence, wherein a token on a first line has a same character and feature correspondence as another token on a second line;
- and
- utilizing, by one or more processors, the positional logic to identify missing values within the text data, as contained within the matrix structure.
