The result is a determin- istic, best-first, O(nlogn) parser, which is signifi- cantly more accurate than best-first transition based parsers, and nears the performance of globally opti- mized parsing models. Therefore. A drawback of this approach is that it is extremely local: while decisions can be based on complex structures on the left, they can look only at a few words to the right. For sequential constraints, this procedure reduces to simple linear programming as the inference process. essarily reﬂect the view of the agencies.

Our method learns to map arithmetic word problem text to math expressions, by learning to select the relevant declarative knowledge for each operation of the solution expression. For the IL dataset, we acquired the, system of (Roy et al., 2015) from the authors, and ran, it with the same fold information. tity Schema extraction is challenging due to parsing is-, sues as well as some non-standard rate patterns, and it, will be one of the future work targets. In this work, we show that numerical reasoning is amenable to automatic data generation, and thus one can inject this skill into pre-trained LMs, by generating large amounts of data, and training in a multi-task setup. stream We show, that features extracted from quantity schemas help rea-, soning effectively about the solution. bles”, the term “more” usually indicates addition. A distance based feature set is extracted for each label from the reduced instance set to facilitate final classification. These problems pose an in-, teresting challenge to the NLP community, due to its, concise and relatively straightforward text, and seem-. to the left and the subtraction chain terms to the right. The ability to compress sentences while preserving their grammaticality and most of their meaning has recently received much attention. Experimental evidence is supplied in the context of an important NLP problem, semantic role labeling. endobj they implicitly assume that similar equation forms have, There is a recent interest in understanding text for, the purpose of solving scientiﬁc and quantitative prob-, lems of various kinds. The right one is monotonic, whereas the left one is not. x�ROHQ��6��A�x�w For all expressions, quantities, there exists only one monotonic expression, tree, and hence, the statement is trivially true.

We show that pre-training our model, GenBERT, on this data, dramatically improves performance on DROP (49.3 $\rightarrow$ 72.3 F1), reaching performance that matches state-of-the-art models of comparable size, while using a simple and general-purpose encoder-decoder architecture.
