LSA as a Measure of Coherence in Second Language Natural Discourse
نویسندگان
چکیده
This study explores Latent Semantic Analysis as a model of coherence relations in spoken discourse. Two studies were conducted on language data from six adult learners of English observed longitudinally for one year. The studies investigated whether LSA values increase as a function of time spent learning English and if there were links between negotiations for meaning and LSA values. Results show that LSA values increase significantly and that negotiations for meaning decrease significantly over time. Negotiations for meaning are also negatively correlated to LSA values. These findings provide evidence of co-referential semantic development in L2 learners. The findings also demonstrate that a lack of semantic similarity in natural spoken discourse is sufficient to trigger negotiations for meaning.

Quantifying incoherence in speech: an automated methodology and novel application to schizophrenia.
Incoherent discourse, with a disjointed flow of ideas, is a cardinal symptom in several psychiatric and neurological conditions. However, measuring incoherence has often been complex and subjective. We sought to validate an objective, intrinsically reliable, computational approach to quantifying speech incoherence. Patients with schizophrenia and healthy control volunteers were administered a v...
متن کاملUse of Cohesive Ties in English as a Foreign Language Students’ Writing
This study aims to understand certain linguistic and semantic resources for the text construction, namely the constructs of cohesion, coherence. The analysis of cohesive ties was conducted on the writing samples of 40 subjects (20 most coherent and 20 least coherent) Iranian undergraduates of English. This prompted us to identify the dominant types of cohesive devices used in most coherent writ...

متن کاملMeasuring Coherence 1 Running head: TEXTUAL COHERENCE USING LATENT SEMANTIC ANALYSIS The Measurement of Textual Coherence with Latent Semantic Analysis
Latent Semantic Analysis is used as a technique for measuring the coherence of texts. By comparing the vectors for two adjoining segments of text in a highdimensional semantic space, the method provides a characterization of the degree of semantic relatedness between the segments. We illustrate the approach for predicting coherence through re-analyzing sets of texts from two studies that manipu...
متن کاملComparison between LSA-LDA-Lexical Chains
This paper presents an analysis of three techniques used for similar tasks, especially related to semantics, in Natural Language Processing (NLP): Latent Semantic Analysis (LSA), Latent Dirichlet Allocation (LDA) and lexical chains. These techniques were evaluated and compared on two different corpora in order to highlight the similarities and differences between them from a semantic analysis v...
