  • This paper shows that a simple two-stage approach to handle non-local dependencies in Named Entity Recognition (NER) can outperform existing approaches that handle non-local dependencies, while being much more computationally efficient. NER systems typically use sequence models for tractable inference, but this makes them unable to capture the long distance structure present in text.

  • Traditional Supply Chain Management (SCM) aims at movement of goods and services from one end of this chain to the other through different stages so as to improve the efficiency, productivity and profitability of the entire process. As SCM spans across the economic functions of the entire value chain of a product or service, it is vital for a company to join in, form, or coordinate its business related supply chains, forming various kinds of business relationships.

  • Information Systems are the software and hardware systems that support data‐ intensive applications. One of the most critical stages of an Information System development cycle is the System Design stage. During this stage the architecture, components, modules, interfaces and system data are defined and modeled in order to fulfill the respective requirements that the developed Information System should meet. For accomplishing this task a number...

  • In this tutorial the sequence analysis for construction stage analysis is outlined. The example selected is a prestressed concrete box girder bridge (FCM) and the construction stage analysis is performed using the Wizard”.In the construction stage analysis the above construction sequences should be considered precisely. The construction stage analysis capability of MIDAS/Civil comprises an activate/deactivate concept of Structure Groups, Boundary Groups, and Load Groups. The analysis sequence of construction stage analysis for FCM is as follows:...

  • We analyse the mathematical structure of portfolio credit risk models with particular regard to the modelling of dependence between default events in these models. We explore the role of copulas in latent variable models (the approach that underlies KMV and CreditMetrics) and use non-Gaussian copulas to present extensions to standard industry models. We explore the role of the mixing distribution in Bernoulli mixture models (the approach underlying CreditRisk+) and derive large portfolio approximations for the loss distribution.

  • This paper addresses the problem of automatically retrieving answers for how-to questions, focusing on those that inquire about the procedure for achieving a specific goal. For such questions, typical information retrieval methods, based on key word matching, are better suited to detecting the content of the goal (e.g., ‘installing a Windows XP server’) than the general nature of the desired information (i.e., procedural, a series of steps for achieving this goal).

  • While computational estimation of difficulty of words in the lexicon is useful in many educational and assessment applications, the concept of scalar word difficulty and current corpus-based methods for its estimation are inadequate. We propose a new paradigm called word meaning maturity which tracks the degree of knowledge of each word at different stages of language learning. We present a computational algorithm for estimating word maturity, based on modeling language acquisition with Latent Semantic Analysis. ...

  • This paper deals with the automatic translation of route descriptions into graphic sketches. We discuss some general problems implied by such inter-mode transcription. We propose a model for an automatic text-to-image translator with a two-stage intermediate representation in which the linguistic representation of a route description precedes the creation of its conceptual representation.

  • Linguistic knowledge usable for machine translation is always imperfect. We cannot be free from the uncertainty of knowledge we have for machine translation. Especially at the transfer stage of machine translation, the selection of target language expression is rather subjective and optional. Therefore the linguistic contents of machine translation system always fluctuate, and make gradual progress. The system should be designed to allow such constant change and improvements.

  • The study presents the application of parabolic model using MEPBAY package to estimate the equilibrium stages of the headland-bay beaches in Binh Thuan and Ninh Thuan provinces. The model results showed that the present shorelines in Phan Thiet, Binh Thuan are not under equilibrium stages. As for Binh Thuan, the shoreline changes with and without structures in Phan Thiet and Hon Rom beaches were predicte.

  • The objective of the past work was to capture the main processes, both biophysical and economic, to reproduce them in a virtual world similar to reality. There have been two stages. In a first step, the team tried to select relevant knowledge to set-up a first conceptual model. As an hydrological model was already developed (Hoanh, et al. 2001), the emphasis was put on the economic and social processes. The first idea was to work on the interactions between decisions making at different scales.

  • All practical systems contain nonlinear dynamics. Control system development for these systems has traditionally been based on linearized system dynamics in conjunction with linear control techniques. Sometimes it is possible to describe the operation of systems by a linear model around its operating points. Linearized system can provide approximate behavior of the system. But in analyzing the overall system behavior, the resulting system model is inadequate or inaccurate. Moreover, the stability of the system cannot be guaranteed.

  • Success in interviewing requires a two-pronged approach. You must address the mechanics and mindset—the visible and invisible elements— of interviewing. Many job seekers focus only on the mechanics of interviewing—what’s the “right” answer to this or that question, how do I follow up after the interview, how do I negotiate salary, and so on. Although these “mechanical” elements are important, they are only half of what you need. It’s like trying to walk on one leg—a distinct disadvantage.

  • Science arises from the very human desire to understand and control the world. Over the course of history, we humans have gradually built up a grand edifice of knowledge that enables us to predict, to varying extents, the weather, the motions of the planets, solar and lunar eclipses, the courses of diseases, the rise and fall of economic growth, the stages of language development in children, and a vast panorama of other natural, social, and cultural phenomena. More recently we have even come to understand some fundamental limits to our abilities to predict.
