A handwritten character recognition system that includes a document scanner for generating scanned images of a previously created document containing handwritten characters, and a pen and digitizing tablet for real time entry of handwritten characters by a user. The handwritten character recognition system includes an image processor connected from the document scanner for receiving the scanned image of a previously created document and generating one or more ordered cluster arrays. The ordered cluster arrays contain spatially ordered coordinate arrays of skeletal image arcs representing and corresponding to the strokes of the handwritten characters wherein the spatial order represents an induced time ordered sequence of creation of the strokes of the handwritten characters that emulates the sequence of creation of the character strokes. A low level recognition processor is connected from the time order induction processor for receiving the ordered cluster arrays and generating a sequential character array wherein the sequential character array contains a character list for each ordered cluster array and wherein each character list contains at least one character identification representing a possible interpretation of the corresponding ordered cluster array. A linguistic post processor may be connected from the low level recognition processor for receiving the sequential character array and generating an output string representing the most probable interpretation of the handwritten characters of the document.

Text management system

An apparatus for generating an index for a collection of words, the apparatus including means for selecting an input word from the collection of words; means for generating words that are lexically related to the input word, wherein the input word and the lexically related words form a group of words; and an indexing engine for representing the occurrence in the collection of words of any of the members of the group by a single member of the group.

Text indexing system

An apparatus for searching a collection of words based upon an input word, the apparatus including means for generating a first set of words containing members that are lexically related to the input word, the first set of words including words that are other than regular inflectional nouns; and also including a search engine for searching the collection of words to detect the occurrence of any of the words from a group of search words, the group of search words including the input word and the first set of words.

Text searching system

A morphological analyzer for analyzing the morphology of an input word, the analyzer including a recognition engine which includes means for finding a stem within the input word; and means for identifying suffixes attached to the stem, wherein the finding means and suffix identifying means cooperate to conduct morphological analysis of the input word from the root to the affix and wherein the recognition engine performs inflectional and derivational analysis, the derivational analysis using more than two derivational suffixes.
