Computing Lexical Contrast
Knowing the degree of semantic contrast between words has widespread application in natural language processing, including machine translation, information retrieval, and dialogue systems. Manually-created lexicons focus on opposites, such as hot and cold. Opposites are of many kinds such as antipodals, complementaries, and gradable. However, existing lexicons often do not classify opposites in...
متن کاملComputing Lexical Chains with Graph Clustering
This paper describes a new method for computing lexical chains. These are sequences of semantically related words that reflect a text’s cohesive structure. In contrast to previous methods, we are able to select chains based on their cohesive strength. This is achieved by analyzing the connectivity in graphs representing the lexical chains. We show that the generated chains significantly improve...
متن کاملExamining lexical tonal contrast in Norwegian using intonation modelling
The lexical accents of one dialect of East Norwegian were examined using a parametric intonation model. The purpose of this investigation was to examine the tonal contrast using a different method, whereby analyses can be done automatically and additional acoustic cues examined. The disyllabic contrast of the Trøndersk dialect had been previously described using F0-measurements in Praat, but th...
متن کاملProsodic and lexical marking of contrast in L2 Italian
We investigated the second language (L2) acquisition of pragmatic categories that are not as consistently and frequently encoded in the L2 than in the first language (L1). Experiment 1 showed that Italian speakers linguistically highlighted affirmative polarity contrast (e.g. The child ate the candies following after The child did not eat the candies) in 34.3% of the cases, by producing a nucle...
متن کاملAsymmetric processing of lexical tonal contrast in Swedish.
Languages such as Swedish use suprasegmental information such as tone, over and above segments, to mark lexical contrast. Theories differ with respect to the abstractness and specification of tone in the mental lexicon. In a forced choice task, we tested Swedish listeners' responses to words with segmentally identical first syllables differing in tonal contours (characterized as Accents 1 and 2...
