  • Patent number: 5396566
    Abstract: A line space baseline adjuster in a handwriting recognition system achieves improved recognition accuracy by normalizing the Cartesian coordinates of the writings captured by a digitizer to coincide with prototype character space. The normalization techniques include weighted average estimation, prototype extraction estimation, extreme point clustering estimation and a combination of prototype extraction estimation and extreme point clustering estimation.

  • Patent number: 5099426
    Abstract: A data processing method is disclosed for storing and retrieving text. The storage part of the method includes the steps of compiling a vocabulary list of words occurring in the text and augmenting the vocabulary list with lemmas of the words in the text, as an augmented word list. It then continues with the steps of compiling a cross reference table relating the lemmas of the words to locations of the words in the text and storing the text, the augmented word list and the cross reference table.The retrieval part of the method includes the steps of inputting a query word to access a portion of the stored text, searching the augmented vocabulary list using the query word as a search term, and accessing the cross reference table with a lemma of the query word to locate the portion of the stored text.The resulting invention enables a faster performance for "fuzzy" searches of text in documents, while enabling the cross reference lists used in the retrieval process, to be compactly stored.
