CECL: a New Baseline and a Non-Compositional Approach for the Sick Benchmark
Yves Bestgen · 2014
This paper describes the two procedures for determining the semantic similarities between sentences submitted for the Se-mEval 2014 Task 1. MeanMaxSim, an unsupervised procedure, is proposed as a new baseline to assess the efficiency gain provided by compositional models.It outperforms a number of other baselines by a wide margin.Compared to the wordoverlap baseline, it has the advantage of taking into account the distributional similarity between words that are also involved in compositional models.The second procedure aims at building a predictive model using as predictors MeanMaxSim and (transformed) lexical features describing the differences between each sentence of a pair.It finished sixth out of 17 teams in the textual similarity sub-task and sixth out of 19 in the textual entailment subtask.
