Mining the Peanut Gallery: Opinion Extraction and Semantic Classification of Product Reviews

by Kushal Dave, Steve Lawrence, David M. Pennock , 2003
"... The web contains a wealth of product reviews, but sifting through them is a daunting task. Ideally, an opinion mining tool would process a set of search results for a given item, generating a list of product attributes (quality, features, etc.) and aggregating opinions about each of them (poor, mixe ..."

Syskill & Webert: Identifying interesting web sites

by Michael Pazzani, Jack Muramatsu, Daniel Billsus - In Proc. 13th Natl. Conf. on Artificial Intelligence , 1998
"... We describe Syskill & Webert, a software agent that learns to rate pages on the World Wide Web (WWW), deciding what pages might interest a user. The user rates explored pages on a three point scale, and Syskill & Webert learns a user profile by analyzing the information on a page. The user p ..."

algorithm on this task. . 1 Introduction There is a vast amount of information on the World Wide Web (WWW) and more is becoming available daily. How can a user locate information that might be useful to that user? In this paper, we discuss Syskill & Webert, a software agent that learns a profile of a

Evaluating Speech-Driven IR in the NTCIR-3 Web Retrieval Task

by Atsushi Fujii, Katunobu Itou - In Proceedings of the 3rd NTCIR Workshop on Research in Information Retrieval, Automatic Text Summarization and Question Answering , 2003
"... Speech recognition has of late become a practical technology for real world applications. For the purpose of research and development in speech-driven retrieval, which facilitates retrieving information with spoken queries, we organized the speech-driven retrieval subtask in the NTCIR-3 Web retrieva ..."

retrieval task. Search topics for the Web retrieval main task were dictated by ten speakers and recorded as collections of spoken queries. We used those queries to evaluate the performance of our speech-driven retrieval system, where speech recognition and text retrieval modules were integrated. The text

Object categorization by learned universal visual dictionary

by J. Winn, A. Criminisi, T. Minka - IN ICCV , 2005
"... This paper presents a new algorithm for the automatic recognition of object classes from images (categorization). Compact and yet discriminative appearance-based object class models are automatically learned from a set of training images. The method is simple and extremely fast, making it suitable ..."

it suitable for many applications such as semantic image retrieval, web search, and interactive image editing. It classifies a region according to the proportions of different visual words (clusters in feature space). The specific visual words and the typical proportions in each object are learned from a

Saliency, Scale and Image Description

by Timor Kadir, Michael Brady , 2001
"... Many computer vision problems can be considered to consist of two main tasks: the extraction of image content descriptions and their subsequent matching. The appropriate choice of type and level of description is of course task dependent, yet it is generally accepted that the low-level or so called ..."

Using the web to obtain frequencies for unseen bigrams

by Frank Keller, Mirella Lapata - COMPUT. LINGUIST , 2003
"... This paper shows that the web can be employed to obtain frequencies for bigrams that are unseen in a given corpus. We describe a method for retrieving counts for adjective-noun, noun-noun, and verb-object bigrams from the web by querying a search engine. We evaluate this method by demonstrating: (a) ..."

UbiCrawler: a scalable fully distributed web crawler

by Paolo Boldi, Bruno Codenotti, Massimo Santini, Sebastiano Vigna - Software: Practice & Experience , 2003
"... We report our experience in implementing UbiCrawler, a scalable distributed web crawler, using the Java programming language. The main features of UbiCrawler are platform independence, fault tolerance, a very effective assignment function for partitioning the domain to crawl, and more in general ..."

Subtopic Structuring for Full-Length Document Access

by Marti A. Hearst, Christian Plaunt , 1993
"... We argue that the advent of large volumes of fulllength text, as opposed to short texts like abstracts and newswire, should be accompanied by corresponding new approaches to information access. Toward this end, we discuss the merits of imposing structure .on fulllength text documents; that is, ..."

Harvesting implicit group attitudes and beliefs from a demonstration Web site.

by Brian A Nosek , Mahzarin R Banaji , Anthony G Greenwald - Group Dynamics, , 2002
"... Respondents at an Internet site completed over 600,000 tasks between October 1998 and April 2000 measuring attitudes toward and stereotypes of social groups. Their responses demonstrated, on average, implicit preference for White over Black and young over old and stereotypic associations linking ma ..."
