Querying heterogeneous XML document collections is an open problem. This will require building some sort of correspondence between the DTD of the different sources. We consider here the problem of matching the structure of XML documents from different sources. We introduce for that a stochastic structured document model and describe preliminary experiments performed on the INEX collection.

Analyses of social mobility remains divided between structuralist (e.g. class structural) and individualist (e.g. status attainment) perspectives. Primarily adopted by sociologists, the former focus on the opportunity structure in which social mobility operates, while the latter, adopted by economists, on the individual attributes associated with mobility. It is becoming increasingly clear howe...

in present paper, housing has been considered as a multidimensional and heterogeneous item. its characteristics has been considered as key elements in determination of unit price of each building unit. the aim of the present paper is to determine the degree of importance which each charactericstics of housing has for users. there fore, hedonic price function of urbun housing in khoramabad estim...

There has been some work on learning bayesian network structure from data. In this paper, there is an investigation of search and score methods for assessing the factors that contribute to greater skill in intelligent games such as chess and go. I will discuss different search strategies and compare their efficiencies. There will also be a discussion on speeding up bayesian network structure

This article focuses on the regional heterogeneity of the mammalian sinoatrial (SA) node in terms of cell morphology, pacemaker activity, action potential configuration and conduction, densities of ionic currents (i(Na), i(Ca,L), i(to), i(K,r), i(K,s) and i(f)), expression of gap junction proteins (Cx40, Cx43 and Cx45), autonomic regulation, and ageing. Experimental studies on the single SA nod...

Social networks have a scale-free property and community structure, many problems in life the characteristic of public goods, such as resource shortage. Due to different preferences individuals, there exist individuals who adopt heterogeneous strategies updating rules network. We investigate evolution cooperation network with goods games influence multiple strategy rules. Here, two types are co...

In recent years, the size of many social networks such as Facebook, MySpace, and LinkedIn has exploded at a rapid pace, because of its convenience in using the internet in order to connect geographically disparate users. This has lead to considerable interest in many graph-theoretical aspects of social networks such as the underlying communities, the graph diameter, and other structural informa...

A social network (SN) is a network containing nodes – social entities (people or groups of people) and links between these nodes. Social networks are examples of more general concept of complex networks and SNs are usually free-scale and have power distribution of node degree. Overall, several types of social networks can be enumerated: (i) simple SNs, (ii) multi-layered SNs (with many links be...

Uncovering community structure is a core challenge in social network analysis. This is a significant challenge for large networks where there is a single type of relation in the network (e.g. friend or knows). In practice there may be other types of relation, for instance demographic or geographic information, that also reveal network structure. Uncovering structure in such multi-relational net...

Social structure and personality (SSP) research is concerned with the relationship between macro-social systems or processes and individual feelings, attitudes, and behaviors. It is considered a perspective or framework rather than a theoretical paradigm because it is not associated with general theoretical claims that transcend specific substantive problems. Rather, it provides a set of orient...
