Representing semantic relatedness
… organised reflects certain explicit and implicit semantic and syntactical coupling relationships which are embedded in its contents. The effective capturing of such content couplings is thereby crucial for a genuine understanding of text representations. It has also led to the recent interest in …

The impact of semantic relatedness on speaking durations in sentences
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-04-12 without embargo terms

Learning sentiment and semantic relatedness in user generated content using neural models
… harnessing and understanding the sentiment and semantics expressed in review platforms and discussion forums. Riding on the recent trends of deep learning, this work applies neural networks to solve these tasks. We design neuralbased models including Convolutional Neural Networks (CNNs) and Long …

The development of semantic memory : a spatial model of animal concepts in schoolchildren, novices and experts
Children’s and adults judgements of semantic relatedness amongst a set of animal terms were compared in order to examine the validity of a spatial model of conceptual development in schoolchildren.

Lexical Representation and Processing in Second Language Learners
… written distractors. The distractors differed in semantic relatedness and gender congruency. There was a clear indication of a gender interference effect when the pictures and the distractors were semantically related, but not when they were unrelated. This gender interference effect suggests that …

Visualizing inference
… as nodes in a graph, clustered by their semantic relatedness. A usability study was performed and the results show users were able to successfully use Alar to determine the cause of an incorrect inference.

Associative Memory Processes in Schizophrenia
… manipulated and studied: 1) orientation to the semantic relatedness of associative pairs; and 2) provision of memory cues at subsequent recall. Behaviorally, schizophrenia participants: like controls) demonstrated significant memory benefits from both the provision of support for effective …

Role of semantic indexing for text classification.
… meanings. Thus, failure to take into account the semantic relatedness between terms means that document similarity is not properly captured in the VSM. To address this problem, semantic indexing approaches have been proposed for modelling the semantic relatedness between terms in document …

Semantic modeling of the natural language of Wikipedia annotations
… of metrics in three concrete tasks: measuring semantic relatedness, solving semantic analogies, and KB completion and refinement. A central feature of our work is a new log-linear discriminative model for the annotations inside a Wikipedia document that we name IBOE (isotropic bag-of-entities): …

Unitization and semantic information
… proposal is that unitization may modulate the semantic relatedness between the two items; thus, unitization of stimuli with little semantic content would lead to reduced effects. To assess this claim, two ERP experiments were performed with semantically sparse stimuli (abstract images and …

The Electrophysiology of Written Informal Language
… made judgments about Twitter targets primed with semantically related or unrelated words. Classic psycholinguistic studies have shown very specific event-related potentials (ERPs) for semantic processing. Most notably, the N400 event-related potential component is an index of lexical expectancy …

Semantic linking and personalization in context
… data and automated processing. The Semantic Web is an extension to the WWW and can overcome its shortcomings. The Semantic Web provides the technology for creating and sharing data in machineprocessable semantics. As a result, the data can be used and shared in effective ways between …

Semantic mapping of the bilingual lexicon : form-to-meaning mapping through computerized testing
… the participants of the study. They performed a semantic relatedness rating task of sixty high frequency semantically related English word pairs on a 6point scale. While thirty word pairs had the same translation (ST) word in Arabic, the other thirty had a different translation (DT) word. Fifteen …

Usefulness of social tagging in organizing and providing access to the web: An analysis of indexing consistency and quality
… investigate the quality of tags, a Latent Semantic Analysis (LSA) was conducted to determine to what extent tags are conceptually related to professionals’ keywords and it was found that tags of higher specificity tended to have a higher semantic relatedness to professionals’ keywords. This …

Augmenting Dynamic Query Expansion in Microblog Texts
… The problems of information overload and semantic mismatch are systemic during the Information Retrieval (IR) tasks undertaken by such systems. In this dissertation, we develop approaches to dynamic query expansion algorithms that can help improve the efficacy of such systems using only a …

Applying Wikipedia to Interactive Information Retrieval
… from Wikipedia, and that accurate measures of semantic relatedness can be efficiently mined from it. Second, we show that Wikipedia provides the necessary features and training data for existing data mining techniques to accurately detect and disambiguate topics when they are mentioned in plain …

Semantics and statistics for automated image annotation
… and also exploits information about the actual semantics of the words used in the annotation process, is able to improve the performance of probabilistic annotation systems. Specifically, I present three experiments. Firstly, I introduce a novel approach that automatically refines the annotation …

Examining the mechanism and influential extent of retrieval-induced forgetting
… items become competitors simply by sharing semantic features with retrieval practiced targets, or whether competitors also must be subsumed within the domain of the retrieval practice cue. Items in the overlap between two categories were retrieval practiced as members of one of the paired …

Detecting and analyzing bursty events on Twitter
… stage characterizes bursts along two dimensions, semantic coherence and causal influence. Semantic coherence measures the semantic relatedness of the tweets in a burst to each other based on a deep neural network derived embedding of tweet contents. Causal influence measures the potential causal …

Semantic Representation of L2 Lexicon in Japanese University Students
In a series of studies using semantic relatedness judgment response times, Jiang (2000, 2002, 2004a) has claimed that L2 lexical entries fossilize with their equivalent L1 content or something very close to it. In another study using a more productive test of lexical knowledge (Jiang 2004b), …
