Formal Semantic Controls over Language Models (2024.lrec-tutorials)

Copied to clipboard

Challenge: Text embeddings provide a concise representation of the semantics of sentences and larger spans of text, rather than individual words, capturing a wide range of linguistic features.
Approach: They propose to shorten the gap between latent semantics and formal symbolics by comparing distributional models to symbolic models grounded on formal linguistics and well-defined mathematical properties.
Outcome: This paper examines the analysis and control of text representations, covering methods from pooling to LLM-based.
Assessing the Limits of the Distributional Hypothesis in Semantic Spaces: Trait-based Relational Knowledge and the Impact of Co-occurrences (2022.starsem-1)

Copied to clipboard

Challenge: a rise in performance in NLP has led to a decrease in interpretability . a recent study examined how neural semantic models capture relational knowledge .
Approach: They evaluate how well English and Spanish semantic spaces capture a particular type of relational knowledge . they also explore the role of co-occurrences in this context .
Outcome: The proposed model can be used to predict traits associated with concepts in English and Spanish.
Can a Gorilla Ride a Camel? Learning Semantic Plausibility from Text (D19-60)

Copied to clipboard

Challenge: Existing work on modeling semantic plausibility has focused on physical plausability but distributional methods fail when tested in supervised settings.
Approach: They propose to use large pretrained language models to model plausibility in supervised settings by extracting attested events from a large corpus and injecting explicit commonsense knowledge into a distributional model.
Outcome: The proposed model is effective in modeling plausibility in a supervised setting.
Comparing Probabilistic, Distributional and Transformer-Based Models on Logical Metonymy Interpretation (2020.aacl-main)

Copied to clipboard

Challenge: Logical metonymies are type clashes between an event-selecting verb and an entity-denoting noun . they are typically interpreted by inferring a hidden event on the basis of contextual cues .
Approach: They propose to use probabilistic and distributional models to model logical metonymy interpretation . they compare models with the best Transformer-based models and some traditional distributional ones .
Outcome: The proposed models perform well on a complex scenario, but low performance on some datasets suggests that logical metonymy is still a challenging phenomenon for computational modeling.
A Tale of Two Laws of Semantic Change: Predicting Synonym Changes with Distributional Semantic Models (2023.starsem-1)

Copied to clipboard

Challenge: Lexical Semantic Change is the study of how the meaning of words evolves through time.
Approach: They propose to use distributional models to detect whether LD or LPC operate for given word pairs.
Outcome: The proposed frameworks achieve a balanced accuracy above 0.6 on the dataset.
A Retrofitting Model for Incorporating Semantic Relations into Word Embeddings (2020.coling-main)

Copied to clipboard

Challenge: Existing word embedding models mix semantic similarity with other types of relatedness.
Approach: They propose a model that leverages relational knowledge available in a knowledge resource to improve word embeddings.
Outcome: The proposed model improves word embeddings on synonymy, antonymy and hypernymy relations in WordNet and significantly improves lexical entailment detection task.
Modeling Event Plausibility with Consistent Conceptual Abstraction (2021.naacl-main)

Copied to clipboard

Challenge: Understanding natural language requires common sense, one aspect of which is the ability to discern the plausibility of events.
Approach: They propose a method of forcing model consistency that improves correlation with human plausibility judgements.
Outcome: The proposed method improves correlation with human plausibility judgements.
BiRRE: Learning Bidirectional Residual Relation Embeddings for Supervised Hypernymy Detection (2020.acl-main)

Copied to clipboard

Challenge: supervised hypernymy detection has been studied under various frameworks . supervised classifiers are more likely to suffer from "lexical memorization"
Approach: They propose a representation learning framework called Bidirectional Residual Relation Embeddings to model the possibility of a term being mapped to another in the embedding space by hypernymy relations.
Outcome: The proposed model outperforms baselines over evaluation frameworks.
Montague semantics and modifier consistency measurement in neural language models (2025.coling-main)

Copied to clipboard

Challenge: Existing studies on distributional language models have been focused on linguistics and their relationship with semantic formalisms for decades.
Approach: They propose a method for measuring compositional behavior in contemporary language embedding models by introducing three new tests inspired by Montague semantics.
Outcome: The proposed method measures compositional behavior in language embedding models on adjectival modifier phenomena in adjective-noun phrases.
Syn2Vec: Synset Colexification Graphs for Lexical Semantic Similarity (2022.naacl-main)

Copied to clipboard

Challenge: In this paper we examine patterns of colexification as an aspect of lexical-semantic organization, and compare several approaches to build large scale graphs across 499 world languages.
Approach: They propose to use patterns of colexification as an aspect of lexical-semantic organization to build large scale synset graphs across a typologically diverse set of 499 world languages.
Outcome: The proposed models are evaluated against human judgments on a semantic similarity task for nine languages.
Distributional Term Set Expansion (L18-1)

Copied to clipboard

Challenge: Iterative term set expansion methods for distributional semantic models are used to label terms belonging to a sought after term set.
Approach: They compare iterative term set expansion methods for distributional semantic models to the Simple Margin method, an active learning approach to classification using Support Vector Machines.
Outcome: The proposed methods outperform centrality and classification based methods for distributional semantic models over five different term sets.
The Contextual Variability of English Nouns: The Impact of Categorical Specificity beyond Conceptual Concreteness (2024.lrec-main)

Copied to clipboard

Challenge: Empirical studies on conceptual abstraction have examined differences in contextual distributions of abstract and concrete concept words.
Approach: They propose to use a model to investigate the interplay between contextual variability and specificity of abstract and concrete concepts.
Outcome: The proposed models show that more specific words have closer contexts than generic terms.
