Latest Patents
One of Howard's latest patents is a "System of document representation retrieval by successive iterated." This innovative information retrieval system is based on probabilities that documents meet information needs. The system estimates the frequency of occurrence of a representation in a collection of documents by identifying the frequency of occurrence in a sample and calculating the difference between the maximum and minimum probable frequencies. If this difference does not exceed a limit, the midpoint of these frequencies is used as the estimated frequency of occurrence. The document distribution probabilities are optimized, and probability thresholds are established for identifying relevant documents. An initial probability threshold is set and adjusted as the probabilities are scored for documents in samples, allowing for an iteratively adjusted document result list.
Another significant patent is related to "Concept matching of natural language queries with a database of document." This computer-implemented process creates a search query for an information retrieval system. It involves a database containing a plurality of stopwords and phrases. The natural language input query defines the text composition of documents to be identified. Each word of the input query is compared to the database to remove stopwords, and the remaining words are stemmed to their basic roots. The sequence of stemmed words is then compared to phrases in the database to identify and substitute phrases in the search query. The completed search query elements form query nodes used to match representation nodes of a document network.
