This paper presents work where a general-purpose text categorization method was applied to categorize medical free-texts. The purpose of the experiments was to examine how such a method performs without any domain-specific knowledge, hand-crafting or tuning. Additionally, we compare the results from the general-purpose method with results from runs in which a medical thesaurus as well as automa...

We study the effect of frequent trading opportunities and categorization on pricing of a risky asset. Frequent opportunities to trade can lead to large distortions in prices if some agents forecast future prices using a simplified model of the world that fails to distinguish between some states. In the limit as the period length vanishes, these distortions take a particular form: the price must...

We discuss the categorization of 20 quantum mechanics problems by 6 physics professors and 22 undergraduate students from two honors-level quantum mechanics courses. Professors and students were asked to categorize the problems based upon similarity of solution. We also had individual discussions with professors who categorized the problems. Faculty members’ categorizations were overall rated b...

Categorization of facial wrinkles is used in dermatology studies to determine the efficacy of a certain treatment over a certain period of time. These studies, however, are limited by the fact that when dermatologists assign these categorizations, it is done so through qualitative, in-vivo observation. The objective of this study was to train a computer to categorize nasolabial wrinkles into on...

In this paper we focus on web sites categorization. We compare some quantitative characteristics of existing web directories, analyze the vocabulary used in descriptions of the web sites in Yahoo web directory and propose an approach to automatically categorize web sites. Our approach is based on the novel concept of salient words. Two realizations of the proposed concept are experimentally eva...

This paper is a critical review of the existing literature examining the validity of nonverbal intelligence as an exclusionary criterion used to categorize children as having specific language impairment. Following the completion of a computerized database search seven articles meeting the inclusion criteria were included for analysis. Study designs include: nonrandomized control trials (betwee...

This paper describes our system, called ITC-UT, for the task-2 (on-line reputation management task) in WePS-3. Our idea is to categorize each query into 3 or 4 classes according to how much the tweets retrieved by the query contain the “true” entity names that refer to the target entity, and then categorize each tweet by the rules defined for each class of queries. We show the evaluation result...
