Abstract:

Abstract Translation equivalence constitutes the basis of all Machine Translation systems including the recent hierarchical and syntax-based systems. For hierarchical MT research it is important to have a tool that supports the qualitative and quantitative analysis of hierarchical translation equivalence relations extracted from word alignments in data. In this paper we present such a toolkit and exemplify some of its uses. The main challenges taken up in designing this tool are the efficient and compact, yet complete, representation of hierarchical translation equivalence coupled with an intu

Abstract:

The main aim of this paper is to discuss the claim that discourse connectives are best treated as indicators of coherence relations between hierarchically organized discourse units. It will be argued that coherence relations cannot be seen as cognitively real entities. Furthermore, there is no evidence for hierarchical organization in discourse. The intuitions underlying the notion of hierarchical discourse structure are instead explained in terms of consequences of processing a text in the search for optimal relevance. This account draws attention to a hitherto not widely discussed set of dat

Abstract:

Common-sense physical reasoning in the real world requires learning about the interactions of objects and their dynamics. The notion of an abstract object, however, encompasses a wide variety of physical objects that differ greatly in terms of the complex behaviors they support. To address this, we propose a novel approach to physical reasoning that models objects as hierarchies of parts that may locally behave separately, but also act more globally as a single whole. Unlike prior approaches, our method learns in an unsupervised fashion directly from raw visual images to discover objects, part

Abstract:

Abstract Topic taxonomy discovery aims at uncovering topics of different abstraction levels and constructing hierarchical relations between them. Unfortunately, most prior work can hardly model semantic scopes of words and topics by holding the Euclidean embedding space assumption. What’s worse, they infer asymmetric hierarchical relations by symmetric distances between topic embeddings. As a result, existing methods suffer from problems of low-quality topics at high abstraction levels and inaccurate hierarchical relations. To alleviate these problems, this paper develops a Box embedding-based

Chinese information processing is a critical step toward cognitive linguistic applications like machine translation. Lexical hyponymy relation, which exists in some Eastern languages like Chinese, is a kind of hyponymy that can be directly inferred from the lexical compositions of concepts, and of great importance in ontology learning. However, a key problem is that the lexical hyponymy is so commonsense that it cannot be discovered by any existing acquisition methods. In this paper, we systematically define lexical hyponymy relationship, its linguistic features and propose a computational app

It is generally acknowledged, that in vocabulary learning and teaching, the main important factors are frequency, meaningful context, and variation in input. Within the last factor, some researchers stress the importance of hierarchical relations between words (paradigmatic relations as in animal - bird - craw), considering these relations essential for network building and vocabulary learning by children. Others believe they are just as important as associative (syntagmatic) relations between words. The findings of the research reported in this article (a curriculum intervention study) show t

Abstract:

According to Dumont, caste can be understood as the institutionalisation of hierarchy, and the principle of hierarchy permeates all relations within Indian society. So understood, caste ideology is uniform throughout the society. This point has been contested by several ethnographers, especially those working among untouchables whom they often described as more ‘egalitarian’. This chapter aims to discuss the concepts of hierarchy and equality among the Paraiyar caste in a Tamil Nadu village. It will show that in spite of a basic acceptance of the value of caste, the Paraiyar espouse a strongly

When professional ethics is applied to hierarchic relationships, specific obligations emerge for managers and subordinates alike. The application of feminist ethics results in the identification of an entirely different, though not contradictory, set of obligations. In t

The joint optimization of representation learning and clustering in the embedding space has experienced a breakthrough in recent years. In spite of the advance, clustering with representation learning has been limited to flat-level categories, which often involves cohesive clustering with a focus on instance relations. To overcome the limitations of flat clustering, we introduce hierarchically-clustered representation learning (HCRL), which simultaneously optimizes representation learning and hierarchical clustering in the embedding space.

World politics is commonly referred to as anarchic, meaning that it lacks a common government. Yet a Hobbesian “war of all against all” does not usually ensue: even sovereign governments that recognize no common authority may engage in limited cooperation. The anarchic structure of world politics does mean, however, that the achievement of cooperation can depend neither on deference to hierarchical authority nor on centralized enforcement. On the contrary, if cooperation is to emerge, whatever produces it must be consistent with the principles of sovereignty and self-help.

The article presents a socio-philosophical analysis of such a phenomenon as a falsehood. The analysis of falsehood is based on the study of inverse relations in a hierarchical system. Since the lie itself can be considered as a hierarchical system, and in addition, it is implemented in a hierarchical social system, this approach is reasonable. Inversion is a form of system relations in which some lower element takes on a dominant value. This situation is observed, in particular, when a falsehood occurs. The ability of the system to form inversions depends on the organizational principles that

Abstract:

In the real world, complex dynamic scenes often arise from the composition of simpler parts. The visual system exploits this structure by hierarchically decomposing dynamic scenes: When we see a person walking on a train or an animal running in a herd, we recognize the individual’s movement as nested within a reference frame that is, itself, moving. Despite its ubiquity, surprisingly little is understood about the computations underlying hierarchical motion perception. To address this gap, we developed a class of stimuli that grant tight control over statistical relations among object velociti

Abstract:

Wireless sensor network is a key technology in the sensing layer of the Internet of Things. Data security in wireless sensor network is directly related to the authenticity and validity of data transmitted in the Internet of Things. Due to the large number and different types of nodes in wireless sensor networks, layered secret key sharing technology is increasingly used in wireless sensor networks. In a hierarchical secret sharing scheme, participants are divided into sections with different permissions for each team, but the same permissions for participants in the same team. In this article

Abstract:

This work presents a theoretical study of outward and inward hierarchical metamaterials. Hierarchically configured multiple electromechanical resonators with shunt circuits are implemented, maintaining the same overall mass as that of a comparable single resonator metamaterial. The governing equations of motion for the outward and inward hierarchical configurations are derived. Dispersion relations are determined for each configuration with varying system parameters to identify key design parameters and assess their impact on the system’s dynamic behavior. Furthermore, outer mass displacement

Abstract:

Distantly Supervised Relation Extraction (DSRE) aims to automatically identify semantic relationships within large text corpora by aligning with external knowledge bases. Despite the success of current methods in automating data annotation, they introduce two main challenges: label noise and data long-tail distribution. Label noise results in inaccurate annotations, which can undermine the quality of relation extraction. The long-tail problem, on the other hand, leads to an imbalanced model that struggles to extract less frequent, long-tail relations. In this paper, we introduce a novel relati

Abstract:

AbstractThe extensive scholarship on ‘varieties of capitalism’ offers some conceptual and theoretical innovations that can be fruitfully employed to analyse the distinctive institutional foundations of capitalism in Latin America, or what could be called hierarchical market economies (HMEs). This perspective helps identify four core features of HMEs in Latin America that structure business access to essential inputs of capital, technology and labour: diversified business groups, multinational corporations (MNCs), low-skilled labour, and atomistic labour relations. Overall non-market, hierarchi
