DLS$@$CU: Sentence Similarity from Word Alignment and Semantic Vector Composition

Md Arafat Sultan, Steven Bethard, Tamara Sumner
2015 Proceedings of the 9th International Workshop on Semantic Evaluation (SemEval 2015)  
We also submitted two runs of a supervised system which uses word alignments and similarities between compositional sentence vectors as its features.  ...  Given two English sentences, each system outputs the degree of their semantic similarity.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.  ...

DLS$@$CU at SemEval-2016 Task 1: Supervised Models of Sentence Similarity

Md Arafat Sultan, Steven Bethard, Tamara Sumner
2016 Proceedings of the 10th International Workshop on Semantic Evaluation (SemEval-2016)  
We describe a set of systems submitted to the SemEval-2016 English Semantic Textual Similarity (STS) task. Given two English sentences, the task is to compute the degree of their semantic similarity.  ...  Each of our systems uses the SemEval 2012-2015 STS datasets to train a ridge regression model that combines different measures of similarity.  ...  Instead of comparing word vectors across the two input sentences, we adopt a simple vector composition scheme to construct a vector representation of each input sentence and then take the cosine similarity  ...

FBK-HLT: A New Framework for Semantic Textual Similarity

Ngoc Phuoc An Vo, Simone Magnolini, Octavian Popescu
2015 Proceedings of the 9th International Workshop on Semantic Evaluation (SemEval 2015)  
This paper reports the description and performance of our system, FBK-HLT, participating in the SemEval 2015, Task #2 "Semantic Textual Similarity", English subtask.  ...  We submitted three runs with different hypothesis in combining typical features (lexical similarity, string similarity, word n-grams, etc) with syntactic structure features, resulting in different sets  ...  structure information, word alignment and semantic word similarity.  ...

Improving Semantic Textual Similarity with Phrase Entity Alignment

Vangapelli Sowmya, Bulusu Vardhan, Mantena Raju
2017 International Journal of Intelligent Engineering and Systems  
A phrase entity is a conceptual unit in a sentence with a subject or an object and its describing words. PEA aligns phrase entities present in the sentences based on their similarity scores.  ...  The textual segments are word phrases, sentences, paragraphs or documents. The similarity can be measured using lexical, syntactic and semantic information embedded in the sentences.  ...  The outperformed system is DLS@CU [21] with mean correlation 0.761, has aligned the related words in two sentences for measuring the semantic equivalent between two sentences.  ...

TKLBLIIR: Detecting Twitter Paraphrases with TweetingJay

Mladen Karan, Goran Glavaš, Jan Šnajder, Bojana Dalbelo Bašić, Ivan Vulić, Marie-Francine Moens
2015 Proceedings of the 9th International Workshop on Semantic Evaluation (SemEval 2015)  
TweetingJay uses a supervised model that combines semantic overlap and word alignment features, previously shown to be effective for detecting semantic textual similarity.  ...  We describe TweetingJay, a system for detecting paraphrases and semantic similarity of tweets, with which we participated in Task 1 of SemEval 2015.  ...  Word Alignment Features We adopt the word alignment features from two alignment-based systems: (1) the DLS@CU system of Sultan et al.  ...

Word Rotator's Distance [article]

Sho Yokoi, Ryo Takahashi, Reina Akama, Jun Suzuki, Kentaro Inui
2020 arXiv   pre-print
Besides, we find how to grow the norm and direction of word vectors (vector converter), which is a new systematic approach derived from sentence-vector estimation methods.  ...  A key principle in assessing textual similarity is measuring the degree of semantic overlap between two texts by considering the word alignment.  ...  Acknowledgments We appreciate the helpful comments from the anonymous reviewers. We thank Emad Kebriaei for indicating how to normalize the sentence vectors.  ...
