This paper investigates the potential use of dialog-based ALICEbots in disseminating terrorism information to the general public. In particular, we study the acceptance and response satisfaction of ALICEbot responses in both the general conversation and terrorism domains. From our analysis of three different knowledge sets: general conversation, terrorism, and combined, we found that users were...

This paper describes a process of building a bilingual syntactically annotated corpus, the PCEDT (Prague Czech-English Dependency Treebank). The corpus is being created at Charles University, Prague, and the release of this corpus as Linguistic Data Consortium data collection is scheduled for the spring of 2004. The paper discusses important decisions made prior to the start of the project and ...

To relax the Term Independence Assumption, Term Dependency is introduced and it has improved retrieval precision dramatically. There are two kinds of term dependencies, one is defined by term proximity, and the other is defined by linguistic dependencies. In this paper, we take a comparative study to re-examine these two kinds of term dependencies in dependence language model framework. Syntact...

Absolute linguistic universals are often justified by cross-linguistic analysis: If all observed languages exhibit a property, the property is taken to be a likely universal, perhaps specified in the cognitive or linguistic systems of language learners and users. In many cases, these patterns are then taken to motivate linguistic theory. Here, we show that cross-linguistic analysis will very ra...

Different from the “black-box” evaluation, the diagnostic evaluation aims to provide a better explanatory power into various aspects of the performance of artificial intelligence systems. However, for machine translation (MT) systems, due to its complexity and knowledge dependency, such diagnostic evaluation often demands a large amount of manual work. To tackle this problem, we propose an auto...

The Arabic Treebank (ATB), released by the Linguistic Data Consortium, contains multiple annotation files for each source file, due in part to the role of diacritic inclusion in the annotation process. The data is made available in both ”vocalized” and ”unvocalized” forms, with and without the diacritic marks, respectively. Much parsing work with the ATB has used the unvocalized form, on the ba...

The paper examines the impact of the income distribution in a less-developed country (LDC) on its patterns of trade, through its influence on home market demand patterns. In a learning-by-doing model with nonhomothetic preferences, the authors show that import substitution under low inequality generates more focused learning and enhances trade potential more effectively. In addition, relative w...

Coverage has been a constant thorn in the side of deployed deep linguistic processing applications, largely because of the difficulty in constructing, maintaining and domaintuning the complex lexicons that they rely on. This paper reviews various strands of research on deep lexical acquisition (DLA), i.e. the (semi-)automatic creation of linguistically-rich language resources, particularly from...

In this paper, the multi-person decision making problems with various different types of incomplete linguistic preference relations are studied. Some new concepts, including incomplete uncertain linguistic preference relation, incomplete triangular fuzzy linguistic preference relation, incomplete trapezoid fuzzy linguistic preference relation, expected incomplete linguistic preference relation ...

This study examined four universal operating principles for first language acquisition proposed by Slobin (1973) and MacWhinney (1978). The applicability of these principles to second-language acquisition was tested by teaching children and adults a miniature linguistic system. The results suggested that the four principles played a major role in the learning of the system by 5-to 7-year-olds b...
