Title: Remi Zajac: Innovator in Query Classification Technologies

Introduction

Remi Zajac is a notable inventor based in Pasadena, CA, who has made significant contributions to the field of query classification technologies. With a total of 6 patents to his name, Zajac's work focuses on enhancing the efficiency and accuracy of web search queries.

Latest Patents

Zajac's latest patents include innovative methods and systems for integrated World Wide Web query classification. One of his notable inventions involves executing a reductionist module on a query to extract a core term, which is then used to search a hash table that maps core terms to corresponding categories. This process derives a first result that includes one of the categories from the search, followed by executing an enrichment module on the query to yield a second result. The enrichment module searches an index of terms mapped to documents and corresponding categories. If the core term is present in the hash table, a weighted average is calculated for the values of the first and second results based on training data. If the core term is not found, and the probability score of the category in the index for the second result meets a minimum confidence value, the core term and corresponding categories are stored in the hash table.

Another significant patent involves a query parser derivation computing device and method for parsing unstructured search queries. This system utilizes conditional random fields, learned by semi-supervised automated learning, to parse structured information from unstructured geographic web-search queries. The method establishes semi-supervised conditional random fields using either a rule-based finite state machine model or a statistics-based conditional random field model. Systematic geographic parsing is applied to enhance the accuracy of local geographical web-based queries.
