Foraging memory: Retrieving words from one and from two semantic categories
… and sub-optimal allocation of time between categories. Experiment 1 tested whether switching between categories leads to a switch cost and/or time-out benefit by having subjects produce items from a category in a continuous three-minute block or multiple blocks that add to three minutes. …

Priming in semantic categories : an evaluation of the effects of similarity and prototypicality
… subjects judged word pairs from six natural semantic categories as containing members from the same category or from different categories. Pairs of both high and low typicality were primed by items of their own or of a different typicality which were similar or dissimilar to the pairs. The …

Was the patient cured? : understanding semantic categories and their relationship in patient records
… words and phrases in the text belonging to semantic categories of interest to doctors (semantic category recognition). For disease and symptoms, we determine whether the problem is present, absent, uncertain, or associated with somebody else (assertion classification). Finally, we classify …

Object Localization, Segmentation, and Classification in 3D Images
… elements, classifying detected objects into semantic categories, and estimating the 3D pose of detected objects within the scene. The increasing availability of 3D sensors motivates us to leverage large amounts of 3D data to train machine learning models to address these tasks in 3D images. …

Die kortikale Verarbeitung semantischer Domänen : eine ERP-Studie
From a semantic point of view concrete nouns can be divided into different categories or domains such as living - non-living as well as into different lexical hierarchies (e.g. dog - beagle). Psycholinguistic and aphasiological case studies as well as neurophysiological investigations have shown …

Russian Bird Names: A Linguistic Analysis
… the ethnobiological context. Chapter 4 discusses semantic classification systems of bird names, and chapters 5-11 contain individual bird name entries for each of the six semantic categories described above plus foreign borrowings. The final two chapters are a summary of the semantic data with an …

StructureTransfer: A Scene Parsing Framework via Graph Matching for Images and Point Clouds
… to densely label the pixels in an image with the semantic categories. In this thesis, we present a scene parsing framework which can work on both images and point clouds. To this end, we develop two separate pipelines for images and point clouds. For point clouds, a coarse segmentation is …

Automatic analysis of medical dialogue in the home hemodialysis domain : structure induction and summarization
… an abstraction of a dialogue into a sequence of semantic categories. This abstraction uncovers structure in informal, verbose conversation between a caregiver and a patient, thereby facilitating automatic processing of dialogue content. Our method induces this structure based on a range of …

Lexical errors produced during category generation tasks by bilingual adults and bilingual typically developing and language-impaired seven to nine-year-old children
… on the development and organization of lexical-semantic categories. The purpose of this study was to examine the types of errors made by bilingual (Spanish-English) children with (n=37) and without (n=35) LI and bilingual adults (n=26) on category generation tasks in both their languages and at …

Exploring social tagging graph for web object classification
… classifying web objects into manageable semantic categories has long been a fundamental preprocess for indexing, browsing, searching, and mining these objects. The explosive growth of heterogeneous web objects, especially non-textual objects such as products, pictures, and videos, has …

Motion in Language and Experience : Actual and Non-actual motion in Swedish, French and Thai
… according to the framework of Holistic Spatial Semantics, which assumes a set of semantic categories and claims that these are distributed across clauses and descriptions rather than being localized to a select few form classes, such as verbs and so-called satellites. The descriptions in the …

Identifying expression fingerprints using linguistic information
… These fingerprints consist of both syntactic and semantic elements of language. Examples of the syntactic elements of expression include structures of embedding and embedded verb phrases. The semantic elements of expression consist of high-level, broad semantic categories. Syntactic and semantic …

Development and Validation of a New Naming Task: The Southwestern Item Fluency Test (SWIFT)

Phase I (Test Development) -Phase I of the study involved development and analysis of the SWIFT, where it was hypothesized that (1) confrontation naming …

Often Wrong but Never in Doubt: Categorized Lists Produce Confident False Memories

A study of the auxiliary in Sesotho
… The study investigates the syntactic and semantic behaviour of Auxiliaries in Sesotho. Having established that there is a category AUX in Sesotho, we then developed a descriptive framework in which auxiliaries in Sesotho participate. In this framework we posit as basic the three …

The role of expertise, semantics, and learning in spatial memory
… exclusivity. These methods include expertise, semantics and learning. It was proposed that expertise would allow for holistic processing of information and it would therefore increase the likelihood of spatial memory integration. Also, the connection between two related spatial memories was …

Getting the gist of websites: Exploring the effects of display duration, size, and resolution
… few studies, no known research has examined what semantic information can be extracted from a web page within a single fixation, but the scene perception literature provides a possible framework for understanding how viewers can extract diverse semantic information from scenes in a glance. The …

A Systemic-Functional Approach to Communicative course Design in English Language Teaching
… method, Inspired by the growing interest in semantics and speech acts, communicative syllabus designers saw language in terms of the meanings speakers need to express, that is, the functions (speech acts) and notions (semantic categories) of language. It is the contention of this thesis that …

Unsupervised Feature Learning for Point Cloud by Contrasting and Clustering with Graph Convolutional Neural Network
