A paraphrase model of a question text inputted by a user is learned, and a paraphrase expression is generated in real time. When information in text set storage unit is updated, text pair extracting unit extracts a paraphrase text pair from the text set storage unit and stores it in text pair storage unit. Model learning unit learns a question text paraphrase model from the paraphrase text pair in text pair storage unit, and stores it in model storage unit. Text pair extracting unit extracts a paraphrase text pair again from the text set storage unit by using the question text paraphrase model which the model storage unit possesses, and stores it in the text pair storage unit. In case where the stored paraphrase text pair is the same as the paraphrase text pair stored in the text pair storage unit, learning of the question text paraphrase model is ended. Candidate creating unit reads the question text paraphrase model from the model storage unit and generates a paraphrase candidate of the inputted question text.

In one aspect of the invention, roughly stated, Applicants have discovered that a compensation material within slot elongated in a direction parallel to a segment of waveguide in an arrayed waveguide grating apparatus can compensate for both first and second order change in refractive index of the base waveguide material over temperature. Unlike the transverse slots of conventional linear athermalization techniques, the elongated slot generally parallel to the base material defines a composite waveguide section having a second order effective index of refraction temperature dependency which can be utilized to accurately minimize the temperature dependence of the overall optical path length to both the first and second order. The techniques described herein are also generalizeable to neutralization of the optical path length temperature dependence to any order.
