Peers in online social learning communities— whether humans, autonomous agents, or web services — can provide feedback when observing the activities performed by others. This feedback may vary in its form. In this paper, we divide feedback into three different types: (1) as opinions which assess the quality of observed activities from the point of view of the opinion holder, (2) as advice which...

most of the studies on the key word method of second/foreign language vocabulary learning have been based on the evidence from laboratory experiments and have primarily involved the use of english key words to learn the vocabularies of other languages. furthermore, comparatively quite limited number of such studies is done in authentic classroom contexts. the present study inquired into the eff...

Over the years, various meta-languages have been used to manually enrich documents with conceptual knowledge of some kind. Examples include keyword assignment to citations or, more recently, tags to websites. In this paper we propose generative concept models as an extension to query modeling within the language modeling framework, which leverages these conceptual annotations to improve retriev...

A ternary-weight neural network (TWN) inspired keyword spotting (KWS) processor is proposed to support complicated and variable application scenarios. To achieve high-precision recognition of 10 keywords under 5dB Clean wide range background noises, a convolution consists 4 layers fully connected layers, with modified sparsity-controllable Truncated Gaussian Approximation based training used. E...

We examine the effectiveness of various speaker recognition approaches based on word-conditioning. Subsets of 62 keywords (used for word-conditioning) are examined for their individual and combined effectiveness for a keyword HMM approach, a supervector keyword HMM approach, a keyword phone Ngrams approach, and a keyword phone HMM approach. Our results demonstrate the effectiveness of acoustic ...

In this chapter, we survey methods that perform keyword search on graph data. Keyword search provides a simple but user-friendly interface to retrieve information from complicated data structures. Since many real life datasets are represented by trees and graphs, keyword search has become an attractive mechanism for data of a variety of types. In this survey, we discuss methods of keyword searc...

Paper presents a survey of methods and approaches for keyword extraction task. In addition to the systematization of methods, the paper gathers a comprehensive review of existing research. Related work on keyword extraction is elaborated for supervised and unsupervised methods, with special emphasis on graphbased methods as well as Croatian keyword extraction. Selectivity-based keyword extracti...
