  • Patent number: 9940408
    Abstract: A trigger query obtaining apparatus includes a graph creating unit, a score calculation unit, a trigger query obtaining unit, and an output unit. The graph creating unit creates a minimal directed graph having nodes each corresponding to a search query included in one of two search logs, and a link directed from one node to another node. The score calculation unit calculates a score for each node of a directed graph composed of minimal directed graphs, using a seed query. The trigger query obtaining unit obtains a trigger query that is a search query corresponding to a node having a score that satisfies a condition. The output unit outputs the trigger query.

  • Publication number: 20090259646
    Abstract: A method and system for automatically calculating, regarding an input search query, a score for evaluating a new query or URL which is a candidate for recommendation information according to a user's search intention. To this end, a recommendation server 10 extracts recommended queries or URLs regarding a certain query, and configures a graph structure in which a plurality of queries are sequentially connected via URLs, based on historical data of URLs searched and browsed by the user in the past. The recommendation server 10 then calculates a score for indicating a degree of popularity of each query, by analyzing a relationship between input and output of edges, i.e. a linking relationship of URLs, in which each query is a node in this graph structure.

  • Patent number: 6207759
    Abstract: A scale has marks or a point-symmetrical shape which are arranged in matrix. The scale and an article to be measured in dimension are positioned without any relative movement. An image sensor unit detects a predetermined portion of the article and the marks of the scale corresponding to the predetermined portion of the article selectively and successively, and the image sensor unit generates output signals in accordance with the detected results of the article and the scale. The output signals are processed to calculate the dimension of the article.

  • Patent number: 4520502
    Abstract: In a pitch synchronous speech synthesizer, an output signal from a pitch phase detector is applied to a delay circuit in a digital filter portion to initialize the output contents of the delay circuit at zero for each pitch period. In this manner the sequence of neighboring frames is smoothed.

  • Patent number: 4489437
    Abstract: A speech synthesizer, using linear predictive coding technique, obtains variable frame lengths by multiplying a pitch period by the number of repetitions, and interpolates PARCOR coefficients at a rate different than the interpolation of amplitude.
