CompareWords: Measuring semantic change in word usage in different corpora

Measuring, Predicting and Visualizing Short-Term Change in Word Representation and Usage in VKontakte Social Network

Language in social media is extremely dynamic: new words emerge, trend and disappear, while the meaning of existing words can fluctuate over time. This work addresses several important tasks of visualizing and predicting short term text representation shift, i.e. the change in a word’s contextual semantics. We study the relationship between short-term concept drift and representation shift on a...

Semantic Maps for Word Alignment in Bilingual Parallel Corpora

Tracking word semantic change in biomedical literature

Up to this point, research on written scholarly communication has focused primarily on syntactic, rather than semantic, analyses. Consequently, we have yet to understand semantic change as it applies to disciplinary discourse. The objective of this study is to illustrate word semantic change in biomedical literature. To that end, we identify a set of representative words in biomedical literatur...

Extracting Constraints on Word Usage from Large Text Corpora

Our research focuses on the identification of word usage constraints from large text corpora. Such constraints are important for natural language systems, both for the problem of selecting vocabulary for language generation and for disambiguating lexical meaning in interpretation. The first stage of our research involves the development of systems that can automatically extract such constraints...

Word Space Modeling for Measuring Semantic Specificity in Chinese

The aim of this study is to use the word-space model to measure the semantic loads of single verbs, profile verbal lexicon acquisition, and explore the semantic information on Chinese resultative verb compounds (RVCs). A distributional model based on Academia Sinica Balanced Corpus (ASBC) with Latent Semantic Analysis (LSA) is built to investigate the semantic space variation depending on the s...
