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.

Claims

1. 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.

2. The process of claim 1, further including the steps of

creating a modified collection of information items by replacing a selected one of the elements of the collection of information items determined to be included in the lexicon data base with an alternate element from the lexicon data base,

extracting the associated values for each of the elements of the modified collection of information items determined to be included in the lexicon data base;

and

establishing, from the extracted associated values, a new measure reflecting the semantic content of the modified collection.

displaying a list of alternate elements in the lexicon data base for the selected element, and

receiving an indication for one of the alternate elements.
