Extracting Relations from Large Plain-Text Collections

by Eugene Agichtein, Luis Gravano , 2000
"... Text documents often contain valuable structured data that is hidden in regular English sentences. This data is best exploited if available as a relational table that we could use for answering precise queries or for running data mining tasks. We explore a technique for extracting such tables fr ..."

from document collections that requires only a handful of training examples from users. These examples are used to generate extraction patterns, that in turn result in new tuples being extracted from the document collection. We build on this idea and present our Snowball system. Snowball

Modeling A-Priori Likelihoods for Angry User Turns with Hidden Markov Models

by Er Schmitt, Tim Polzehl, Wolfgang Minker
"... Current studies dealing with the detection of angry users in automated telephone-based speech applications take acoustic and sometimes linguistic information into account in order to classify the emotional state of the caller in single user turns. Angry user turns, however, don’t appear from nowhere ..."

Relational Databases for Querying XML Documents: Limitations and Opportunities

by Jayavel Shanmugasundaram, Kristin Tufte, Gang He, Chun Zhang, David DeWitt, Jeffrey Naughton , 1999
"... XML is fast emerging as the dominant standard for representing data in the World Wide Web. Sophisticated query engines that allow users to effectively tap the data stored in XML documents will be crucial to exploiting the full power of XML. While there has been a great deal of activity recently prop ..."

A framework for clustering evolving data streams. In:

by Charu C Aggarwal , T J Watson , Resch Jiawei Ctr , Jianyong Han , Wang , Philip Yu , T J Watson , Resch Ctr - Proc of VLDB’03, , 2003
"... Abstract The clustering problem is a difficult problem for the data stream domain. This is because the large volumes of data arriving in a stream renders most traditional algorithms too inefficient. In recent years, a few one-pass clustering algorithms have been developed for the data stream proble ..."
Abstract - Cited by 359 (36 self) - Add to MetaCart
simple one-pass clustering algorithm over an entire data stream of a few years is dominated by the outdated history of the stream. The exploration of the stream over different time windows can provide the users with a much deeper understanding of the evolving behavior of the clusters. At the same time

Why Cryptosystems Fail

by Ross Anderson , 2005
"... Designers of cryptographic systems are at a disadvantage to most other engineers, in that information on how their systems fail is hard to get: their major users have traditionally been government agencies, which are very secretive about their mistakes. In this article, we present the results of a s ..."

Democratizing content publication with Coral

by Michael Freedman, Eric Freudenthal, David Mazières - IN NSDI , 2004
"... CoralCDN is a peer-to-peer content distribution network that allows a user to run a web site that offers high performance and meets huge demand, all for the price of a cheap broadband Internet connection. Volunteer sites that run CoralCDN automatically replicate content as a side effect of users acc ..."

Steps Toward an Ecology of Infrastructure: Design and Access for Large Information Spaces

by Susan Leigh Star, Karen Ruhleder - Information Systems Research , 1996
"... We analyze a large-scale custom software effort, the Worm Community system (WCS), a collaborative system designed for a geographically dispersed community of geneticists. There were complex challenges in creating this infrastructural tool, ranging from simple lack of resources to complex organizatio ..."

organizational and intellectual communication failures and tradeoffs. Despite high user satisfaction with the system and interface, and extensive user needs assessment, feedback and analysis, many users experienced difficulties in signing on and use. The study was conducted during a time of unprecedented growth

The status of the Tropical Rainfall Measuring Mission (TRMM) after two years in orbit

"... The potential to achieve dynamic, scalable and cost-effective marketplaces and eCommerce solutions has driven recent research efforts towards so-called Semantic Web Services, that are enriching Web services with machine-processable semantics. To this end, the Web Service Modeling Ontology (WSMO) pro ..."

A Pattern Approach to Interaction Design

by Jan O. Borchers , 2000
"... To create successful interactive systems, user interface designers need to cooperate with developers and application domain experts in an interdisciplinary team. These groups, however, usually miss a common terminology to exchange ideas, opinions, and values. This paper presents an approach that use ..."
