On the Replicability of Combining Word Embeddings and Retrieval Models

no code implementations13 Jan 2020 Luca Papariello, Alexandros Bampoulidis, Mihai Lupu

We replicate recent experiments attempting to demonstrate an attractive hypothesis about the use of the Fisher kernel framework and mixture models for aggregating word embeddings towards document representations and the use of these representations in document classification, clustering, and retrieval.

Addressing Cross-Lingual Word Sense Disambiguation on Low-Density Languages: Application to Persian

no code implementations16 Nov 2017 Navid Rekabsaz, Mihai Lupu, Allan Hanbury, Andres Duque

We explore the use of unsupervised methods in Cross-Lingual Word Sense Disambiguation (CL-WSD) with the application of English to Persian.

Toward Incorporation of Relevant Documents in word2vec

no code implementations20 Jul 2017 Navid Rekabsaz, Bhaskar Mitra, Mihai Lupu, Allan Hanbury

As an alternative, explicit word representations propose vectors whose dimensions are easily interpretable, and recent methods show competitive performance to the dense vectors.

Character-based Neural Embeddings for Tweet Clustering

1 code implementation WS 2017 Svitlana Vakulenko, Lyndon Nixon, Mihai Lupu

In this paper we show how the performance of tweet clustering can be improved by leveraging character-based neural networks.

Standard Test Collection for English-Persian Cross-Lingual Word Sense Disambiguation

1 code implementation LREC 2016 Navid Rekabsaz, Serwah Sabetghadam, Mihai Lupu, Linda Andersson, Allan Hanbury

In this paper, we address the shortage of evaluation benchmarks on Persian (Farsi) language by creating and making available a new benchmark for English to Persian Cross Lingual Word Sense Disambiguation (CL-WSD).

Applying Random Indexing to Structured Data to Find Contextually Similar Words

no code implementations LREC 2012 Danica Damljanovi{\'c}, Udo Kruschwitz, M-Dyaa Albakour, Johann Petrak, Mihai Lupu

Our approach is based on exploiting the structure inherent in an RDF graph and then applying the methods from statistical semantics, and in particular, Random Indexing, in order to discover contextually related terms.
