Crowdsourcing-based semantic relation recognition for natural language questions over RDF data

ABSTRACT

Natural language query systems over RDF data need to rely on the semantic relations in query. First, we propose the new crowdsourcing model that used to produce semantic relations dataset. The model not only inherits completeness of the iterative model and accuracy of the parallel model, but also saves human resources. Second, we mine the rules of semantic relation recognition from the correlations between dependency structures and semantic relations. Third, we propose an algorithm of semantic relation recognition for natural language query over RDF data, and experiments demonstrate that it can recognize more semantic relations than existing methods.

Land Reform: Taking a Long(er) View

The paper proposes a broad argument that the end of state–led development from the 1970s coincided with (i) the final wave of major redistributive land reform, and its place within transitions to capitalism, that lasted from about 1910 to the 1970s, and (ii) the beginnings of contemporary 'globalization'. Self–styled 'new wave' agrarian reform in the age of neo–liberalism, centred on property rights, is unlikely to deliver much on its claims to both stimulate agricultural productivity and reduce rural poverty. The reasons are grounded in the basic relations and dynamics of capitalism, and how these are intensified and reshaped by and through globalization. Understanding these processes, with all their inevitable unevenness, requires (i) recognizing that the historical conditions of the 'classic' agrarian question no longer apply, and (ii) developing the means to investigate and understand better the changing realities facing different agrarian classes within a general tendency to the concentration of capital and fragmentation of labour, including how the latter may generate new agrarian questions of labour.     

对我国城市房屋拆迁中存在问题的法律思考

城市房屋拆迁,既关系国家、开发建设单位、被拆迁单位及亿万城镇居民的利益,又关系到城市规划的具体落实,这是一个敏感而又普遍的社会问题,已成为近几年全社会高度关注的社会问题之一.基于城市房屋拆迁所引发的拆迁人与被拆迁人利益冲突问题比较严重,引发矛盾冲突的根本原因是我国现行的拆迁法律制度和政策存在问题,本文着重分析了我国城市房屋拆迁法律制度和政策存在的几个问题,并从学理上提出解决矛盾的建议.

The Theory of Socially Embedded Games: Applications and Extensions to Open and Closed Games

An earlier article, drawing on the mathematical theory of rules and rule complexes, extends and generalizes game theory (GGT). The theory has been used to conceptualize and analyze diverse social relationships, roles, and games as particular types of rule complexes.For instance, a social role, as a major basis of a parent's action in a game, consists of at least four key components – which are mathematical objects – in the determination of action: value complex, model of reality (including beliefs and knowledge bases), a repertoire of acts, routines, programs, and strategies, and modality, a role-specific algorithm for determining or generating action in game settings. This article applies and extends GGT in analyses of a market bargaining game (a type of open game) and of the classical game of prisoners' dilemma (a type of closed game). The applications show the concrete effects of social embeddedness on game structuring, game interaction patterns and outcomes, and social equilibria.

我国生态旅游可持续发展的探讨

生态旅游含义复杂，具有原生性，资源利用的适度性和可持续性，开发与保护的辩证性和系统的复杂性。生态旅游的可持续发展要以可持续理论为基本原则，以生态学及生态经济学为依据，以区位理论为其开发及营销战略的指导。本文在分析我国开发生态旅游中存在的典型问题后，运用生态旅游可持续发展所必需遵循的原则，阐述了我国生态旅游可持续发展的具体对策。
