Supervised Categorization for Habitual versus Episodic Sentences
نویسندگان
چکیده
We implement and evaluate systems for automatically distinguishing habitual and episodic sentences. Using features such as tense, aspect, noun phrase characteristics, temporal modifiers, specific adverb modifiers, and specific verb auxiliaries on genericity we built and evaluated a supervised machine learning classifier that provides 86.3% precision in disambiguating habitual and episodic sentences. This compares against a majority class baseline of 73.1% precision. In order to support these objectives, a representative corpus sample was hand-annotated.

Automatic Text Categorization by Unsupervised Learning
The goal of text categorization is to classify documents into a certain number of predefined categories. The previous works in this area have used a large number of labeled training doculnents for supervised learning. One problem is that it is difficult to create the labeled training documents. While it is easy to collect the unlabeled documents, it is not so easy to manually categorize them fo...
متن کاملJournal of Experimental Psychology: Human Learning and Memory
The possible empirical bases for the semantic-episodic distinction are examined. Two kinds of results are particularly relevant. The first concerns whether the same functional laws can be demonstrated for semantic as for episodic memory. Failure to demonstrate such generalities argues for the distinction, whereas success at demonstrating generalities argues against the need for such a distincti...

In this paper, extractive speech summarization using different machine learning algorithms was investigated. The task of Speech summarization deals with extracting important and salient segments from speech in order to access, search, extract and browse speech files easier and in a less costly manner. In this paper, a new method for speech summarization without using automatic speech recognitio...
متن کاملSupervised versus unsupervised categorization: two sides of the same coin?
Supervised and unsupervised categorization have been studied in separate research traditions. A handful of studies have attempted to explore a possible convergence between the two. The present research builds on these studies, by comparing the unsupervised categorization results of Pothos et al. ( 2011 ; Pothos et al., 2008 ) with the results from two procedures of supervised categorization. In...
متن کاملFrom episodic to habitual prospective memory: ERP-evidence for a linear transition
Performing a prospective memory task repeatedly changes the nature of the task from episodic to habitual. The goal of the present study was to investigate the neural basis of this transition. In two experiments, we contrasted event-related potentials (ERPs) evoked by correct responses to prospective memory targets in the first, more episodic part of the experiment with those of the second, more...
