Graph based semi-supervised approach for information extraction
- In Proceedings of the TextGraphs Workshop in the Human Language Technology Conference of the North American Chapter of the Association of Computational Linguistics (HLT/NAACL
"... Classification techniques deploy supervised labeled instances to train classifiers for various classification problems. However labeled instances are limited, expensive, and time consuming to obtain, due to the need of experienced human annotators. Meanwhile large amount of unlabeled data is usually ..."

is usually easy to obtain. Semi-supervised learning addresses the problem of utilizing unlabeled data along with supervised labeled data, to build better classifiers. In this paper we introduce a semi-supervised approach based on mutual reinforcement in graphs to obtain more labeled data to enhance
A Semi-Supervised Approach to Modeling Web Search
"... Web search is an interactive process that involves actions from Web search users and responses from the search engine. Many research efforts have been made to address the problem of understanding search behavior in general. Some of this work focused on predicting whether a particular user has succee ..."

labeled and unlabeled data to learn better models of user behavior that can be used to predict search success more effectively. We present a semi-supervised approach to modeling Web search satisfaction. The proposed approach can use either labeled data only or both labeled and unlabeled data. We show
A Semi-supervised Approach to Space Carving
"... In this paper, we present a semi-supervised approach to space carving by casting the recovery of volumetric data from multiple views into an evidence combining setting. The method presented here is statistical in nature and employs, as a starting point, a manually obtained contour. By making use of ..."

A semi-supervised approach to question classification ∗
"... Abstract. This paper presents a machine learning approach to question classification. We have defined a kernel function based on latent semantic information acquired from unlabeled data. This kernel allows including external semantic knowledge into the supervised learning process. We have combined t ..."

Music Genre Classification: A Semi-supervised Approach
"... Abstract. Music genres can be seen as categorical descriptions used to classify music basing on various characteristics such as instrumentation, pitch, rhythmic structure, and harmonic contents. Automatic music genre classification is im-portant for music retrieval in large music collections on the ..."

on the web. We build a classifier that learns from very few labeled examples plus a large quantity of unlabeled data, and show that our methodology outperforms existing supervised and unsupervised approaches. We also identify salient features useful for music genre classification. We achieve 97.1 % accuracy
EMDC: A Semi-supervised Approach for Word Alignment
"... This paper proposes a novel semisupervised word alignment technique called EMDC that integrates discriminative and generative methods. A discriminative aligner is used to find high precision partial alignments that serve as constraints for a generative aligner which implements a constrained version ..."

Active Semi-Supervised Approach for Checking App Behavior Against Its Description
"... Abstract—Mobile applications are popular in recent years. They are often allowed to access and modify users ’ sensitive data. However, many mobile applications are malwares that inappropriately use these sensitive data. To detect these malwares, Gorla et al. propose CHABADA which compares app behavi ..."

In this work, we extend the work by Gorla et al. by proposing an active and semi-supervised approach for detecting malwares. Different from CHABADA, our approach will make use of both
Improving BAS Committee Performance with a Semi-Supervised Approach
"... Abstract. Semi-supervised Learning is a machine learning approach that, by making use of both labeled and unlabeled data for training, can significantly improve learning accuracy. Boosting is a machine learning technique that combines several weak classifiers to improve the overall accuracy. At each ..."
