Collocational grammar system |
September 19, 1989 |
| A system for the grammatical annotation of natural language receives natural language text and annotates each word with a set of tags indicative of its possible grammatical or syntactic uses. An empirical probability of collocation function defined on pairs of tags is iteratively ext |

Sentence analyzer |
September 5, 1989 |
| An apparatus for the grammatical anlysis of digitally encoded text material receives encoded text, annotates each word of the text with a tag, and processes the annotated text to identify basic syntactic units such as noun phrases and verb groups. A clausal analyzer then operates on the |

Word annotation system |
September 5, 1989 |
| A system for annotating digitally encoded text includes a dictionary of base forms. For each base form, a first set of tags represents possible grammatical and syntactic properties of the word, and may encode inflectional paradigms of the base form, or feature agreement behavior and |

Automated word substitution using numerical rankings of structural disparity between misspelled |
November 8, 1988 |
| A spelling correction system compares a correctly spelled word with an incorrectly spelled word to determine the degree of substitutability. If the system determines that the words are highly similar, the system flags the correct word as exclusively substitutable for the incorrect word. |

Method and apparatus for text analysis |
September 20, 1988 |
| An electronic text analyzer operates on an ordered block of digitally coded text by analyzing sequential strings thereof to determine paragraph and sentence boundaries. Each string is broken down into component words. Possible abbreviations are identified and checked against a table of |

Apparatus and method for linguistic expression processing |
September 13, 1988 |
| An apparatus and method for linguistic expression processing provides features for spelling verification, correction, and dictionary database storage. The system utilizes a linguistically salient word skeleton-forming process to correct both typrographic and cognitive spelling errors |

Method and apparatus for generating word skeletons utilizing alpha set replacement and omission |
March 8, 1988 |
| Automated spelling correction converts, by prescribed linguistic procedures, each word to be corrected to a skeleton, and compares that skeleton with a data base of skeletons derived by identical linguistic procedures from a dictionary of correctly spelled words. In the event of a ma |

Method and apparatus for the electronic storage and retrieval of expressions and linguistic info |
February 9, 1988 |
| The invention relates to a system for storing, retrieving, and processing linguistic information. In one aspect, the invention provides a system for storing linguistic expressions, which system includes a main dictionary storage section and three coding sections, one for each of regular |

Textual database system using skeletonization and phonetic replacement to retrieve words matchin |
June 16, 1987 |
| An electronic database search system can identify database records having textual expressions that match, or are similar to, an operator-designated search expression. The system features a mechanism for transforming linguistic expressions, e.g., words, into linguistically salient word |

Graphic word spelling correction using automated dictionary comparisons with phonetic skeletons |
April 1, 1986 |
| Automated spelling correction converts, by prescribed linguistic procedures, each word to be corrected to a skeleton, and compares that skeleton with a data base of skeletons derived by identical linguistic procedures from a dictionary of correctly spelled words. In the event of a ma |
