process is discussed and divided into subprocesses and/or categories of methods to provide a reference to describe and compare the more than 130 publications covered by the survey. References are included throughout the paper to exemplify important issues and their relations to the various methods. A

An approach to the construction of classifiers from imbalanced datasets is described. A dataset is imbalanced if the classification categories are not approximately equally represented. Often real-world data sets are predominately composed of ``normal'' examples with only a small

One of the major applications of data mining is in helping companies determine which potential customers to market to. If the expected pro t from a customer is greater than the cost of marketing to her, the marketing action for that customer is executed. So far, work in this area has considered

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

A neuropsychological theory is proposed that assumes category learning is a competition between separate verbal and implicit (i.e., procedural-learning-based) categorization systems. The theory assumes that the caudate nucleus is an important component of the implicit system and that the anterior

This paper describes a program that disambiguates English word senses in unrestricted text using statistical models of the major Roget's Thesaurus categories. Roget's categories serve as approximations of conceptual classes. The categories listed for a word in Roget's index tend

Total character count: 44,877 06/04/2005 2 Studies of skilled reading, its acquisition in children, and its impairment in patients with pure alexia, all highlight the importance of the left posterior fusiform cortex in visual word recognition. Its precise functional contribution, however, remains unclear. We used visual masked priming and fMRI to elucidate the specific functional contribution of this region to reading and found that: i) unlike words, repetition of pseudowords (“hith-hith”) did not produce a neural priming effect in this region, ii) orthographically related words such as “corner-corn ” did produce a neural priming effect, but iii) this orthographic priming effect was reduced when prime-target pairs were semantically related (“teacher-teach”). We argue that these findings conflict with the notion that visual word forms are stored in this region and instead propose that the posterior fusiform cortex acts as an interface between visual form information and higher-order properties of the stimulus such as its associated sound and meaning. Importantly, this function is not specific to reading but is also engaged when processing any meaningful visual stimulus.

The authors reviewed more than 70 studies concerning employees ’ general belief that their work organization values their contribution and cares about their well-being (perceived organizational support; POS). A meta-analysis indicated that 3 major categories of beneficial treatment received

major new challenge: generalization across object categories, not just across instances within a category. In this paper, we also introduce a novel feature selection method for learning attributes that generalize well across categories. We support our claims by thorough evaluation that provides insights
