Determining the semantic orientation of terms through gloss classification

Andrea Esuli, Fabrizio Sebastiani
2005 Proceedings of the 14th ACM international conference on Information and knowledge management - CIKM '05  
The method is based on the quantitative analysis of the glosses of such terms, i.e. the definitions that these terms are given in on-line dictionaries, and on the use of the resulting term representations  ...  Functional to the extraction of opinions from text is the determination of the orientation of "subjective" terms contained in text, i.e. the determination of whether a term that carries opinionated content  ...  "noun" senses of good will likely generate noisy representations.  ...

Continuous Sign Language Recognition through Cross-Modal Alignment of Video and Text Embeddings in a Joint-Latent Space

Ilias Papastratis, Kosmas Dimitropoulos, Dimitrios Konstantinidis, Petros Daras
2020 IEEE Access  
The purpose of the proposed cross-modal alignment is the modelling of intra-gloss dependencies and the creation of more descriptive video-based latent representations for CSLR.  ...  The proposed method is trained jointly with video and text latent representations. Finally, the aligned video latent representations are classified using a jointly trained decoder.  ...  The hidden state of the LSTM layer h y k encapsulates the history of the sentence up to gloss y k , i.e., all previous words.  ...

Master Thesis: Neural Sign Language Translation by Learning Tokenization [article]

Alptekin Orbay
2020 arXiv   pre-print
Lastly, we discuss the advantages of sign-level tokenization over gloss-level tokenization.  ...  Therefore, we aim to develop a generic sign-level tokenization layer so that it is applicable to other domains without further effort.  ...  In this study, glosses and sentences are learned jointly, yet requires tedious gloss annotations. It uses common representations of images as tokens.  ...
