Abstract: Reference identification and resolution identifies reference text fragments in a document and associates referenced object text fragments in the document with the identified reference text fragments. Reference profiles are abstracted from the document. Each reference profile specifies at least a reference number and an object type identifier. A reference profile is paired with an object text fragment of the document containing the reference number of the reference profile. The pairing is repeated to associate reference profiles with object text fragments. A reference text fragment of the document satisfying one of the reference profiles is associated with the object text fragment paired with the satisfied reference profile. The associating is repeated to associate reference text fragments of the document with object text fragments.

Abstract: A method is provided for operating a computing device to create a document structure model of a computer parsable text document utilizing recognition of at least one ordered sequence of identifiers in the document. The method includes converting a computer parsable text document of any format to an alternative structured language format to form a converted document. The text of the converted document is fragmented into an ordered sequence of text fragments within a text format. The text fragments are enumerated to obtain a sequence of terms. At least one optimal sub-sequence of terms is identified from among the sequence of terms, with an optimal sub-sequence being one or more longest increasing sub-sequence(s). The computer parsable text document is annotated with tags, with the tags including information derived from identification of the optimal sub-sequence(s). The annotated document is displayed on the graphical user interface.

Abstract: A system and method that converts legacy and proprietary documents into extended mark-up language format which treats the conversion as transforming ordered trees of one schema and/or model into ordered trees of another schema and/or model. In embodiments, the tree transformers are coded using a learning method that decomposes the converting task into three components which include path re-labeling, structural composition and input tree traversal, each of which involves learning approaches. The transformation of an input tree into an output tree may involve labeling components in the input tree with valid labels or paths from a particular output schema, composing the labeled elements into the output tree with a valid structure, and finding such a traversal of the input tree that achieves the correct composition of the output tree and applies structural rules.

Abstract: A method for identifying header/footer content of a document, in order to sequence text fragments comprising recognizable text blocks as derived from the document. The textual variability of lines comprised of text blocks, including the different kinds of text blocks within the line is analyzed for assessment of textual variability. Header/footer zones are defined by textual content having a low textual variability. An alternative embodiment identifies pagination constructs by comparing selected text-boxes for similarity and proximity and clustering the text boxes satisfying a predetermined similarity value, wherein the clustered text boxes are deemed to comprise pagination constructs.

The method comprises computing a first leading distance between a first baseline of a first token element, and a second baseline of a second token element. The method further comprises defining a block with the first token element and the second token element, and characterizing the first leading distance as a leading distance of the block. The method further comprises computing a second leading distance between the second baseline and a third baseline of a third token element. The method furthermore comprises, grouping the third token element in to the block based on a first difference between the second leading distance and the leading distance of the block lying within a first predefined threshold value.

Abstract: A method for detection of page numbers in a document includes identifying a plurality of text fragments associated with a plurality of pages of a document. From the identified text fragments, at least one sequence is identified. Each identified sequence includes a plurality of terms. Each term of the sequence is derived from a text fragment selected from the plurality text fragments. The terms of an identified sequence comply with at least one predefined numbering scheme which defines a form and an incremental state of the terms in a sequence. A subset of the identified sequences which cover at least some of the pages of the document is computed. Terms of at least some of the subset of the identified sequences are construed as page numbers of pages of the document. Additional page numbers may be identified by considering one or more features of the terms in the subset of identified sequences.

Abstract: To detect captions in a document that includes text fragments and objects of interest, a signature is assigned to each text fragment. The signature is the value for that text fragment of a text fragment representation comprising at least one text fragment attribute. A caption signature is identified as a signature assigned to a substantial number of text fragments that are near at least one object of interest in the document. One or more captions are detected as one or more text fragments each assigned a caption signature.

Abstract: A method and apparatus is provided for converting a document in a first format essentially comprising a flat layout structure into a structured document in a hierarchical form in accordance with predetermined attributes identified from the input format. The process comprises fragmenting the input document into a plurality of document content elements in accordance with a predetermined set of document attributes identifiable from the input document format. The content elements are clustered into selective sets having similar document attributes. The clustered sets are validated with reference to common textual properties organizational content common in documents in the collection. The clustered sets are then categorized into predetermined categories comprising structured elements of the structured document format and the document content elements are organized by hierarchical dependency from the predetermined categories wherein the organized document elements comprise the desired structured document format.
