In predicate-argument structure analysis, it is important to capture non-local dependencies among arguments and interdependencies between the sense of a predicate and the semantic roles of its arguments. However, no existing approach explicitly handles both non-local dependencies and semantic dependencies between predicates and arguments.
In this paper we investigate a structured model for jointly classifying the sentiment of text at varying levels of granularity. Inference in the model is based on standard sequence classiﬁcation techniques using constrained Viterbi to ensure consistent solutions. The primary advantage of such a model is that it allows classiﬁcation decisions from one level in the text to inﬂuence decisions at another. Experiments show that this method can signiﬁcantly reduce classiﬁcation error relative to models trained in isolation. ...
SAP2000 represents the most sophisticated and user-friendly release of the SAP series of computer programs. When initially released in 1996, SAP2000 was the first version of SAP to be completely integrated within Microsoft Windows. It features a powerful graphical user interface that is unmatched in terms of ease-of-use and productivity. Creation and modification of the model, execution of the analysis, and checking and optimization of the design, and production of the output are all accomplished using this single interface.
In this paper, we present a structural learning model for joint sentiment classiﬁcation and aspect analysis of text at various levels of granularity. Our model aims to identify highly informative sentences that are aspect-speciﬁc in online custom reviews.
We describe a new loss function, due to Jeon and Lin (2006), for estimating structured log-linear models on arbitrary features. The loss function can be seen as a (generative) alternative to maximum likelihood estimation with an interesting information-theoretic interpretation, and it is statistically consistent. It is substantially faster than maximum (conditional) likelihood estimation of conditional random ﬁelds (Lafferty et al., 2001; an order of magnitude or more).

We present a generative model for the unsupervised learning of dependency structures. We also describe the multiplicative combination of this dependency model with a model of linear constituency. The product model outperforms both components on their respective evaluation metrics, giving the best published ﬁgures for unsupervised dependency parsing and unsupervised constituency parsing. We also demonstrate that the combined model works and is robust cross-linguistically, being able to exploit either attachment or distributional regularities that are salient in the data. ...

Prior to construction of any structural system, an extensive engineering design and analysis process must be undertaken. During this process, many engineering assumptions are routinely used in the application of engineering principles and theories to practice.

AutoCAD Structural Detailing - Formwork Drawings has been developed to make it easier to prepare formwork drawings (plans of arrangement of structural positions) of structure components. AutoCAD Structural Detailing - Formwork Drawings is the program for defining a structure model, creating drawings (sections, views, projections), creating formwork drawings of single structure elements, preparing tables of material elements and estimating costs of a structure.
After providing the basic background in electromagnetic theory necessary to utilize the software, the author of Ebook Antenna and EM Modeling with Matlab describes the benefits and many practical uses of the Matlab. Sergey Makarov's text utilizes the widely used Matlab(r) software, which offers a more flexible and affordable alternative to other antenna and electromagnetic modeling tools currently available.
The final article in this section presents a modification to the Green’s function
approach for modeling acoustic pressure, where the use of conformal mapping is
replaced by a group of bound vortices. The author shows that the approach is readily
extended to three dimensions. The method is discussed in the context of aircraft noise.
