The FF planning system: Fast plan generation through heuristic search

by Jörg Hoffmann, Bernhard Nebel - Journal of Artificial Intelligence Research , 2001
"... We describe and evaluate the algorithmic techniques that are used in the FF planning system. Like the HSP system, FF relies on forward state space search, using a heuristic that estimates goal distances by ignoring delete lists. Unlike HSP's heuristic, our method does not assume facts to be ind ..."

to be independent. We introduce a novel search strategy that combines Hill-climbing with systematic search, and we show how other powerful heuristic information can be extracted and used to prune the search space. FF was the most successful automatic planner at the recent AIPS-2000 planning competition. We review

Ontology Mapping: The State of the Art

by Yannis Kalfoglou, Marco Schorlemmer , 2003
"... Ontology mapping is seen as a solution provider in today's landscape of ontology research. As the number of ontologies that are made publicly available and accessible on the Web increases steadily, so does the need for applications to use them. A single ontology is no longer enough to support t ..."

such mappings has been the focus of a variety of works originating from diverse communities over a number of years. In this article we comprehensively review and present these works. We also provide insights on the pragmatics of ontology mapping and elaborate on a theoretical approach for defining ontology

Extracting Policy Positions from Political Texts Using Words as Data

by Michael Laver, Kenneth Benoit, Trinity College - American Political Science Review , 2003
"... We present a new way of extracting policy positions from political texts that treats texts not as discourses to be understood and interpreted but rather, as data in the form of words. We compare this approach to previous methods of text analysis and use it to replicate published estimates of the pol ..."

Conceptual-Model-Based Data Extraction from Multiple-Record Web Pages

by D. W. Embley, D.M. Campbell, Y.S. Jiang, S.W. Liddle, D.W. Lonsdale, Y. -k. Ng, R.D. Smith - Data & Knowledge Engineering , 1999
"... Electronically available data on the Web is exploding at an ever increasing pace. Much of this data is unstructured, which makes searching hard and traditional database querying impossible. Many Web documents, however, contain an abundance of recognizable constants that together describe the esse ..."

the essence of a document's content. For these kinds of data-rich, multiple-record documents (e.g. advertisements, movie reviews, weather reports, travel information, sports summaries, financial statements, obituaries, and many others) we can apply a conceptual-modeling approach to extract

VENKATESH S.: Video abstraction: A systematic review and classification

by Ba Tu Truong, Svetha Venkatesh - ACM Transactions on Multimedia Computing, Communications and Applications
"... The demand for various multimedia applications is rapidly increasing due to the recent advance in the computing and network infrastructure, together with the widespread use of digital video technology. Among the key elements for the success of these applications is how to effectively and efficiently ..."

information in the minimum time. Over past years, various ideas and techniques have been proposed towards the effective abstraction of video contents. The purpose of this article is to provide a systematic classification of these works. We identify and detail, for each approach, the underlying components

T.: Microformats: a pragmatic path to the Semantic Web

by Rohit Khare - Proceedings of the 15 th international conference on World Wide Web. (2006
"... Microformats are a clever adaptation of semantic XHTML that makes it easier to publish, index, and extract semi-structured information such as tags, calendar entries, contact information, and reviews on the Web. This makes it a pragmatic path towards achieving the vision set forth for the Semantic W ..."

The visual word form area: Expertise for reading in the fusiform gyrus. Trends in Cognitive Sciences,

by Bruce D Mccandliss , Laurent Cohen , Stanislas Dehaene , 2003
"... Brain imaging studies reliably localize a region of visual cortex that is especially responsive to visual words. This brain specialization is essential to rapid reading ability because it enhances perception of words by becoming specifically tuned to recurring properties of a writing system. The or ..."

adults possess a special form of visual expertise that allows their visual system to process words efficiently. Within less than 250 ms of viewing a written word, the visual system extracts the information needed to identify its linguistic significance, despite wide variations in print, script, font

Towards a cognitive psychology of syntax: Information processing contributions to sentence formulation

by J. Kathryn Bock - Psychological Review , 1982
"... it is widely acknowledged that characteristics of the general information processing svstem in which sentence formulation occurs mav provide constraints on syntax in language use. This paper proposes one possibli&urce of such constraints. Ev-idence is reviewed indicating that the syntax of sente ..."

The existence of such an interaction argues that the utterance formulation system is not strictly hierarchical, as most current approaches to sentence production imply. A broad framework for models of production is outlined that incorporates

Movie review mining and summarization

by Li Zhuang, Feng Jing, Xiao-yan Zhu - In Proceedings of the International Conference on Information and Knowledge Management (CIKM , 2006
"... With the flourish of the Web, online review is becoming a more and more useful and important information resource for people. As a result, automatic review mining and summarization has become a hot research topic recently. Different from traditional text summarization, review mining and summarizatio ..."

and summarization aims at extracting the features on which the reviewers express their opinions and determining whether the opinions are positive or negative. In this paper, we focus on a specific domain – movie review. A multi-knowledge based approach is proposed, which integrates WordNet, statistical analysis
