Determining the Semantic Weight of Concepts
Unlike conventional search-and-retrieval programs, Syntactica does not simply match strings of letters to other strings of letters in an index. It analyzes concepts in the context of the sentence structures in which the words reside. To take a simple example, a concept will have a different weight if it contains a noun than if it contains a modifier. Syntactica takes into account far more complex aspects of English grammar than the part of speech in which the words are used to determine if a concept is relevant or not.

The program first determines the semantic weight of the concept from the dictionary. The dictionary filters all the short words such as articles out and gives them their meanings. The dictionary assigns a series of codes to the concepts based on what their dictionary definition is together with how much information is contained in them. After the semantic weight is determined, the program determines the concept’s place in the text’s syntactic structure to determine its overall relevance. Once a concept’s relevance has been determined, the program follows more rules that compare the weight of all the concepts within a text, and generates summaries based on the relevance of all its concepts to produce the desired output.
