The importance of copy detection has led to a substantial amount of research in recent years, among which Bag of visual Words (BoW) plays an important role due to its ability to effectively handling occlusion and some minor transformations. One crucial issue in BoW approaches is the size of vocabulary. BoW descriptors under a small vocabulary can be both robust and efficient, while keeping high...

Should computer-based study tasks use multiple-choice or constructed-response question formats? It was hypothesized that a constructed-response study task (CR) with feedback would be superior to multiple-choice study tasks that allowed either single or multiple tries (STF and MTF). Two additional recognition study task treatments were included that required an overt constructed response after f...

In this paper we describe stochastic finite state model for named entity (NE) identification, based on explicit word-level -gram relations. NE categories are incorporated in the model as word attributes. We present an overview of the approach, describing how the extensible vocabulary model may be used for NE identification. We report development and evaluation results on a North American Broadc...

Students learning facts such as foreign language vocabulary often rely on a self-testing procedure in which they cue themselves with the English word and try to recall the foreign language target, instead of simply memorizing cue-target pairs. The value of this strategy has been empirically verified by a long history of research, yet existing computational models of human learning do not addres...

In unseren vorangegangenen Arbeiten haben wir die Schwächen der BPMN Geschäftsprozessmodellierung in dem von uns untersuchten Bereich des Precision Dairy Farmings (PDF) aufgezeigt. Dies betraf insbesondere die Darstellung und die Integration von Geschäftsregeln in der Prozessdefinition. Daher war der nächste Schritt die Standardisierung der Ausdrucksweise der Regeln. Als Ausgangspunkt diente un...

Abstract Eighty Japanese learners of English as a foreign language encountered 40 target words in one four experimental conditions (three encounters, six three encounters with talker variability, and variability). A picture-naming test was conducted times (pretest, immediate posttest, delayed posttest) elicited speech samples were scored terms form-meaning connection (spoken form recall) word s...

Judit Ács Research Institute for Linguistics Hungarian Academy of Sciences [email protected] Abstract We describe a method for expanding existing dictionaries in several languages by discovering previously non-existent links between translations. We call this method triangulation and we present and compare several variations of it. We assess precision manually, and recall by comparing the ...

Automatic methods for vocabulary expansion are valuable in supporting the development of terminological resources. Here, we evaluate two methods based on distributional semantics for extracting terms that belong to a certain semantic category. In a list of 1000 terms extracted from a corpus of Swedish medical text, the best method obtains a recall of 0.53 and 0.88, respectively, for identifying...

The way we study material influences how well we retain it. Psychologists have established that spaced practice leads to better long-term retention of declarative knowledge (facts such as foreign language vocabulary) than massed practice. However, determining the appropriate amount of time between practice sessions is complex and depends on the duration of time over which the material must be a...
