Latest Patents

One of Bessho's latest patents is a "Word vector changing device, method, and program." This invention aims to arrange words so that the distance between a given pair of words is appropriate. The device utilizes a concept base, which consists of pairs of words and their corresponding concept vectors, along with a dictionary of semantically related or distant word pairs. The conversion means in this patent associates a magnitude of a difference vector with word pairs, optimizing the representation of words in a way that minimizes the total sum of the magnitudes corresponding to every word pair.

Another significant patent is a "Model generation device, text search device, model generation method, text search method, data structure, and program." This invention takes a group of text pairs for learning, where each pair consists of a first text and a second text that serves as an answer to questions posed about the first text. The query expansion model learned from this input generates an expanded query for the text serving as a query, enhancing the efficiency of text searches.
