Abstract

A process for analyzing the informational and semantic content of an information source, such as text, a picture, or a video sequence. After compiling a lexicon of information elements, values are assigned to each element for relevant categories. A target information store is compared to the lexicon to calculate values for each category. Information elements are substituted to modify the store to the desired level. The methodology has broad application to analysis of semantic content of visual, verbal, and auditory input streams, such as graphics, text, video, and music. In a textual example, a word list is compiled and values are assigned to the determined categories. Individual words and entire documents are compared to this repository for calculating semantic content in various categories. Values for semantic content in each category are determined. Samples with undesirable scores can be adjusted through substitutions to modify the document. This process may be automated using a computer system for analysis and modification.

Dependent claims

A computer-implemented process for evaluating semantic content of a collection of information items comprising the steps of:

referencing a lexicon data base having a list of information elements and associated values for predetermined categories of semantic content;
determining which of the elements of the collection of information items are in the lexicon data base;
extracting the associated values for each of the elements of the collection of information items determined to be in the lexicon data base;
and
establishing, from the extracted associated values, a measure reflecting the semantic content of the collection.

A computer readable medium containing instructions for directing a computer to perform a process for evaluating semantic content of a collection of information items, the medium comprising:

means for causing a computer to reference a lexicon data base having a list of information elements and associated values for predetermined categories of semantic content;
means for causing a computer to determine which of the elements of the collection of information items are included in the lexicon data base;
means for causing a computer to extract the associates values for each of the elements of the collection of information items determined to be included in the lexicon data base;
and
means for causing a computer to establish, from the extracted associated values, a measure reflecting the semantic content of the collection.
