Word embedding models learn semantically rich vector representations of words and are widely used to initialize natural processing language (NLP) models. The popular continuous bag-of words (CBOW) model of word2vec learns a vector embedding by masking a given word in a sentence and then using the other words as a context to predict it. A limitation of CBOW is that it equally weights the context words when making a prediction, which is inefficient, since some words have higher predictive value than others. We tackle this inefficiency by introducing the Attention Word Embedding (AWE) model, which integrates the attention mechanism into the CBOW model. We also propose AWE-S, which incorporates subword information. We demonstrate that AWE and AWE-S outperform the state-of-the-art word embedding models both on a variety of word similarity datasets and when used for initialization of NLP models.

Musical Word Embedding for Music Tagging and Retrieval IEEE Transactions on Audio, Speech and Language Processing (submitted) - SeungHeon Doh, Jongpil Lee, Dasaem Jeong, Juhan NamDEMO: https://seungheondoh.github.io/musical_word_embedding_demo/ Word embedding has become an essential means for text-based information retrieval. Typically, word embeddings are learned from large quantities of general and unstructured text data. However, in the domain of music, the word embedding may have difficulty understanding musical contexts or recognizing music-related entities like artists and tracks. To address this issue, we propose a new approach called Musical Word Embedding (MWE), which involves learning from various types of texts, including both everyday and music-related vocabulary. We integrate MWE into an audio-word joint representation framework for tagging and retrieving music, using words like tag, artist, and track that have different levels of musical specificity. Our experiments show that using a more specific musical word like track results in better retrieval performance, while using a less specific term like tag leads to better tagging performance. To balance this compromise, we suggest multi-prototype training that uses words with different levels of musical specificity jointly. We evaluate both word embedding and audio-word joint embedding on four tasks (tag rank prediction, music tagging, query-by-tag, and query-by-track) across two datasets (Million Song Dataset and MTG-Jamendo). Our findings show that the suggested MWE is more efficient and robust than the conventional word embedding.

Die automatisierte Verarbeitung natürlicher Sprache bietet großes Potenzial, um neues Wissen aus unstrukturierten Daten zu gewinnen. Für die Bewältigung dieser Herausforderung haben sich in den vergangenen Jahren Word-Embedding-Verfahren bewährt, da diese semantische Ähnlichkeiten abbilden können. Durch die intensive Forschung entstehen stetig neue Verfahren. Je nach Aufgabe ist dabei aber nicht immer eindeutig, welches Verfahren für den Einzelfall empfehlenswert ist. Um dieses Problem zu adressieren, liefert dieser Beitrag einen Word-Embedding Benchmark, der die NLP-Tasks Ähnlichkeit, Analogie und (Multiclass-/Multilabel-) Klassifikation für einheitlich trainierte Word-Embeddings betrachtet und neben der Genauigkeit auch auf Kriterien wie die Trainingsdauer und die Hardwareressourcen eingeht. Zudem werden die Standardparametereinstellungen der Word-Embeddings modifiziert, um die Ergebnisse zu validieren. Die besten Ergebnisse lieferten die Word-Embeddings FastText und ELMo. Mit diesem Benchmark werden Data Scientisten bei der Auswahl eines Word-Embeddings für den Einsatz in entsprechenden NLPAufgaben unterstützt.

Learning a high-dimensional dense representation for vocabulary terms, also known as a word embedding, has recently attracted much attention in natural language processing and information retrieval tasks. The embedding vectors are typically learned based on term proximity in a large corpus. This means that the objective in well-known word embedding algorithms, e.g., word2vec, is to accurately predict adjacent word(s) for a given word or context. However, this objective is not necessarily equivalent to the goal of many information retrieval (IR) tasks. The primary objective in various IR tasks is to capture relevance instead of term proximity, syntactic, or even semantic similarity. This is the motivation for developing unsupervised relevance-based word embedding models that learn word representations based on query-document relevance information. In this paper, we propose two learning models with different objective functions; one learns a relevance distribution over the vocabulary set for each query, and the other classifies each term as belonging to the relevant or non-relevant class for each query. To train our models, we used over six million unique queries and the top ranked documents retrieved in response to each query, which are assumed to be relevant to the query. We extrinsically evaluate our learned word representation models using two IR tasks: query expansion and query classification. Both query expansion experiments on four TREC collections and query classification experiments on the KDD Cup 2005 dataset suggest that the relevance-based word embedding models significantly outperform state-of-the-art proximity-based embedding models, such as word2vec and GloVe.

Word Sense Disambiguation (WSD) which aims to identify the correct sense of a target word appearing in a specific context is essential for web text analysis. The use of glosses has been explored as a means for WSD. However, only a few works model the correlation between the target context and gloss. We add to the body of literature by presenting a model that employs a multi-head attention mechanism on deep contextual features of the target word and candidate glosses to refine the target word embedding. Furthermore, to encourage the model to learn the relevant part of target features that align with the correct gloss, we recursively alternate attention on target word features and that of candidate glosses to gradually extract the relevant contextual features of the target word, refining its representation and strengthening the final disambiguation results. Empirical studies on the five most commonly used benchmark datasets show that our proposed model is effective and achieves state-of-the-art results.

Recent studies in the literature demonstrate that human language can be effectively modeled as a complex network, commonly referred to as a word co-occurrence network.These networks exhibit characteristics typical of scale-free and small-world networks, aligning them with fundamental concepts in network theory.The use of word co-occurrence networks in text classification has shown notable success, primarily due to their ability to capture the structural and syntactic properties of a text, without relying on parsers that require a deeper linguistic knowledge of the language.However, the increasing use of word embeddings across various applications highlights the importance of integrating contextual and semantic information, which co-occurrence networks, in their traditional form, may lack.In this research, we propose to extend the modeling of word co-occurrence networks by incorporating word embedding data to generate virtual edges, thereby unifying syntactic, semantic, and contextual elements within the same network.This approach aims to improve several aspects of text classification, particularly in terms of quality, robustness, and adaptability to short texts, which often present unique challenges.Due to the generalizability of the proposed model and the flexible nature of embeddings, we believe that these networks can further our understanding of how word embeddings operate within complex network structures.The results of our experiments reveal that the use of virtual edges generated from embeddings such as GloVe, Word2Vec, and FastText enhances the discriminative power of the network, significantly improving text classification performance.Additionally, we discovered that the most optimized results are achieved when stop-words are retained and a simple global thresholding strategy is applied to establish virtual edges.Moreover, incorporating word embeddings in these networks not only enhances but also maintains a high level of informativeness, allowing the network to better distinguish between human texts and nonsensical texts over short and long texts.Finally, the combination of word embeddings with stop-word filtering, provides the network with semantic richness, giving the ability to capture semantical and context information of texts.However, maintaining word embedding without stop-word filtering, retains its ability to capture the underlying syntactic structure, making it possible to identify the linguistic properties of different languages.This approach adds robustness to word co-occurrence networks, preserving their initial syntactic capabilities without being compromised by the addition of virtual edges.
