TL;DR: The overall architecture of the goal oriented parsing system, along with the basic features of the parsing algorithm, are illustrated, based on the new concept of hierarchical parsing and is mainly directed by the semantics of the language.
Abstract: In this paper, a novel approach to natural language understanding, called goal oriented parsing, is presented. Such a model of comprehension is embedded in the more general frame of interpersonal communication and is applied to the person-machine interaction task. It is based on the claim that understanding imperative natural language is strongly dependent both on the goal of the speaker and on the nature of the hearer. This assumption has proved appropriate for the design of effective and robust natural language interfaces to artificial systems. This approach is supported by the development of an experimental project, called NLI, for enquiring in Italian a relational data base. NLI is to date running on a PDP 11/34 computer at the University of Udine. In this paper we illustrate the overall architecture of the system, along with the basic features of the parsing algorithm. This is based on the new concept of hierarchical parsing and is mainly directed by the semantics of the language. The role of clarification dialogue to overcome critical situations is discussed as well. The use of goal oriented parsing in dealing with full query text and anaphora is also exploited. Several meaningful examples are presented. Comparisons with related works are outlined and promising directions deserving further investigation are presented.

TL;DR: In this article, a finite-element procedure is presented for the calculation of two-dimensional, viscous, incompressible flows of a recirculating nature, where velocity and pressure are uncoupled and the equations are solved one after the other.
Abstract: A finite-element procedure is presented for the calculation of two-dimensional, viscous, incompressible flows of a recirculating nature. As in finite-difference procedures, velocity and pressure are uncoupled and the equations are solved one after the other. Velocity fields are determined by first calculating intermediate velocity values based on an estimated pressure distribution and then obtaining appropriate corrections to satisfy the continuity equation. Illustrative examples involving flow in the entrance region between parallel plates, lid-driven cavity flow, and flow around an obstacle demonstrate the accuracy and capabilities of the proposed technique.

TL;DR: In this article, two different models for the damping moment to introduce in the rolling equation of the ship are proposed, which contain two terms, respectively linear-quadratic and linear-cubic in the angular velocity, and furthermore they foresee a non-linear term representing the dependence of damping from the heeling angle.

TL;DR: In the paper the specifications and basic methodologies of SUSY are introduced, its architecture is illustrated with particular attention to the organization of the basic algorithms, and an example to support the novel approach proposed is described.
Abstract: The paper is devoted to present a new approach to automatic abstracting which is supported by the development of SUSY, an experimental system currently being implemented at the University of Udine (Italy). The original contribution of the research reported is mostly focused on the role of forward and backward reasoning in the abstracting activity. In the paper the specifications and basic methodologies of SUSY are introduced, its architecture is illustrated with particular attention to the organization of the basic algorithms, and an example to support the novel approach proposed is described.

TL;DR: A proposal is developed in order to overcome inadequacy and to emphasize the basic aspects of theoretical Computer Science.
Abstract: Theoretical foundations of Computer Science (Automata Theory, Complexity, Formal Languages ) are taught almost everywhere within Computer Science curricula However little effort is usually done to present this material in an integrated and motivated way, that is in such a way that its application and use in the solution of practical problems appears to any studentA proposal is developed in order to overcome this inadequacy and to emphasize the basic aspects of theoretical Computer Science

Journal ArticleDOI
TL;DR: In this paper, an iterative procedure for a vector optimization problem in a differentiable context is presented, where the limit 2 of a sequence is fixed a priori and does not depend on the choice both of the initial point x0 and of the procedure itself.

TL;DR: In this paper, the process of the reduction of a principal fiber bundle P(M, G) to a reduced subbundle Q(M and H) is analyzed in view of applications to the description of symmetries of gauge theories.
Abstract: The process of the reduction of a principal fibre bundle P(M, G) to a reduced subbundle Q(M, H) is analysed in view of applications to the description of symmetries of gauge theories. The main idea is to relate symmetries of the nonuniqueness of the reduction by gauging the different ways in which for each fiber the unbroken group H is imbedded into the large group G. Gauge theories encompassing gravitation are especially taken into account.
