Algebraic Graph Theory

by Chris Godsil, Mike Newman , 2011
"... Algebraic graph theory comprises both the study of algebraic objects arising in connection with graphs, for example, automorphism groups of graphs along with the use of algebraic tools to establish interesting properties of combinatorial objects. One of the oldest themes in the area is the investiga ..."

is the investigation of the relation between properties of a graph and the spectrum of its adjacency matrix. A central topic and important source of tools is the theory of association schemes. An association scheme is, roughly speaking, a collection of graphs on a common vertex set which fit together in a highly

Authoritative Sources in a Hyperlinked Environment

by Jon M. Kleinberg - JOURNAL OF THE ACM , 1999
"... The network structure of a hyperlinked environment can be a rich source of information about the content of the environment, provided we have effective means for understanding it. We develop a set of algorithmic tools for extracting information from the link structures of such environments, and repo ..."

, and report on experiments that demonstrate their effectiveness in a variety of contexts on the World Wide Web. The central issue we address within our framework is the distillation of broad search topics, through the discovery of “authoritative ” information sources on such topics. We propose and test

The Generative Lexicon

by James Pustejovsky - Computational Linguistics , 1991
"... this paper, I will discuss four major topics relating to current research in lexical semantics: methodology, descriptive coverage, adequacy of the representation, and the computational usefulness of representations. In addressing these issues, I will discuss what I think are some of the central prob ..."

Inferring Web Communities from Link Topology

by David Gibson, Jon Kleinberg, Prabhakar Raghavan , 1998
"... The World Wide Web grows through a decentralized, almost anarchic process, and this has resulted in a large hyperlinked corpus without the kind of logical organization that can be built into more traditionally-created hypermedia. To extract meaningful structure under such circumstances, we develop a ..."

of central, "authoritative" pages linked together by "hub pages"; and they exhibit a natural type of hierarchical topic generalization that can be inferred directly from the pattern of linkage. Our investigation shows that although the process by which users of the Web create pages

Trust as a social reality

by J. David Lewis, Andrew Weigert - Social Forces , 1985
"... Although trust is an underdeveloped concept in sociology, promising theoretical formulations are available in the recent work of Luhmann and Barber. This socio-logica! version complements the psychological and attitudinal conceptualizations of experimental and survey researchers. Trust is seen to in ..."

to include both emotional and cognitive dimensions and to function as a deep assumption underwriting so-cial order. Contemporary examples such as lying, family exchange, monetary atti-tudes, and litigation illustrate the centrality of trust as a sociological reality. In recent years, sociologists have begun

Predicting Central Topics in a Blog Corpus from a Networks Perspective

by Srayan Datta
"... In today’s content-centric Internet, blogs are becoming increasingly popular and important from a data analysis perspective. According to Wikipedia, there were over 156 million public blogs on the Internet as of February 2011. Blogs are a reflection of our contemporary society. The contents of diffe ..."

of different blog posts are important from social, psychological, economical and po-litical perspectives. Discovery of impor-tant topics in the blogosphere is an area which still needs much exploring. We try to come up with a procedure using prob-abilistic topic modeling and network cen-trality measures which

LexRank: Graph-based lexical centrality as salience in text summarization

by Dragomir R. Radev - Journal of Artificial Intelligence Research , 2004
"... We introduce a stochastic graph-based method for computing relative importance of textual units for Natural Language Processing. We test the technique on the problem of Text Summarization (TS). Extractive TS relies on the concept of sentence salience to identify the most important sentences in a doc ..."

document or set of documents. Salience is typically dened in terms of the presence of particular important words or in terms of similarity to a centroid pseudo-sentence. We consider a new approach, LexRank, for computing sentence importance based on the concept of eigenvector centrality in a graph

The role of assessment in a learning culture

by Lorrie A. Shepard - Educational Researcher , 2000

This article is about classroom assessment—not the kind of assessments used to give grades or to satisfy the ac-countability demands of an external authority, but rather the kind of assessment that can be used as a part of instruction to support and enhance learning. On this topic, I am especially i ..."
