Computer method and apparatus of information management and navigation

A computer method of navigating information comprising:

• receiving a first source of information and one or more second sources of information, each second source having a parent-child relationship with the first source, the first source being the parent;
• automatically extracting keywords from the first source and each of the second sources in a manner employing knowledge management including knowledge management services or a semantic lexicon tool, such that, for each extracted keyword, the keyword correlates the first source and at least one second source, resulting in a respective set of second sources for each extracted keyword and resulting in precise keywords that enhance retrieval of second sources of information, and wherein for each extracted keyword, knowledge management automatically records semantic relationships between the extracted keyword and its respective set of second sources;
• and
• displaying to a user a listing of the keywords resulting from the automatic extracting and from the automatically recorded semantic relationships, the displayed listing enabling the user to navigate the one or more second sources, different keywords in the displayed listing effectively referencing the different respective sets of second sources and the different respective sets of second sources having subject matter of the first source of information shown to the user;
• wherein automatically extracting includes:
• extracting initial keywords from the first source;
• forming an initial taxonomy from the extracted initial keywords;
• detecting in the second sources words that match the initial taxonomy but that do not duplicate the extracted initial keywords of the first source;
• and
• combining the extracted initial keywords from the first source and the detected words from the second sources, said combining forming the listing of keyword.

A computer information navigation system, comprising:

• in a computer memory:
• (i) a first source of information;
• and
• (ii) one or more second sources of information, information from each second source having a parent-child relationship with the first source information, the first source information being parent information;
• in a processor coupled for communication with the computer memory, a keyword engine executed by the processor and responsive to the first and second sources of information, the keyword engine extracting keywords from the first source information and from each of the second sources information in a manner employing knowledge management including knowledge management services or a semantic lexicon tool, such that, for each extracted keyword, the extracted keyword is related to the first source information and at least one second source information, the keyword engine producing respective groupings of second source information related by keyword and resulting in precise keywords that enhance retrieval of second sources of information, and for each extracted keyword, the knowledge management automatically records semantic relationships between the extracted keyword and its respective set of second sources, wherein the keyword engine extracting keywords includes:
• extracting initial keywords from the first source;
• forming an initial taxonomy from the extracted initial keywords;
• detecting in the second sources words that match the initial taxonomy but that do not duplicate the extracted initial keywords of the first source;
• and
• combining the extracted initial keywords from the first source and the detected words from the second sources, said combining forming the listing of keyword;
• and
• an output member coupled to the keyword engine to receive the extracted keywords, the output member executed by a computer and in response to the received extracted keywords and automatically recorded semantic relationships thereof, displaying to a user a listing of the received extracted keywords in a manner enabling the user to navigate the one or more second sources of information, different keywords in the displayed listing referencing the different respective groupings of second source information and the different respective sets of second sources having subject matter of the first source of information shown to the user.
