Persuasion aims at forming one’s opinion and action via a series of persuasive messages containing persuader’s strategies. Due to its potential application in dialogue systems, the task strategy recognition has gained much attention lately. Previous methods on user intent systems adopt recurrent neural network (RNN) or convolutional (CNN) model context conversational history, neglecting tactic ...

In order to decide if systems are running according to their usual trend, it is necessary to compare against a performance baseline that defines an operating envelope. We describe how baselines can be derived from passive stores of performance data, which are typically flat text files or databases. Baselines can be built as needed by varying the baseline norm, granularity, update frequency, etc...

A task-oriented evaluation of text understanding systems was prepared and conducted. Nine different NLP systems participated in the evaluation. NOSC collected 150 texts to be used as development (i.e. training) and test data and prepared explanatory documentation on them. The performance task--a simulated database update task--and the expected outputs for each text were defined. A scoring syste...

In this paper, we offer broad insight into the underperformance of Arabic constituency parsing by analyzing the interplay of linguistic phenomena, annotation choices, and model design. First, we identify sources of syntactic ambiguity understudied in the existing parsing literature. Second, we show that although the Penn Arabic Treebank is similar to other treebanks in gross statistical terms, ...

We analyze a general model of rationing in which agents have baselines, in addition to claims against the (insufficient) endowment of the good to be allocated. Many reallife problems fit this general model (e.g., bankruptcy with prioritized claims, resource allocation in the public health care sector, water distribution in drought periods). We introduce (and characterize) a natural class of all...

We introduce a new operator for general rationing problems in which, besides conflicting claims, individual baselines play an important role in the rationing process. The operator builds onto ideas of composition, which are not only frequent in rationing, but also in related problems such as bargaining, choice, and queuing. We characterize the operator and show how it preserves some standard ax...
