Automatic Selection of Context Configurations for Improved Class-Specific Word Representations

2017

This paper is concerned with identifying contexts useful for training word representation models for different word classes such as adjectives (A), verbs (V), and nouns (N). We introduce a simple yet effective framework for an …

Symmetric Pattern Based Word Embeddings for Improved Word Similarity Prediction

2015

We present a novel word level vector representation based on symmetric patterns (SPs). For this aim we automatically acquire SPs (e.g., "X and Y") from a large corpus of plain text, and generate vectors where …

BLEU is Not Suitable for the Evaluation of Text Simplification

2018

BLEU is widely considered to be an informative metric for text-to-text generation, including Text Simplification (TS). TS includes both lexical and structural aspects. In this paper we show that BLEU is not suitable for the …
