Unitization and semantic information
… of an item and its related contextual information, and a general sense of familiarity for the item. Performance on recollection-based associative memory tests can be supported by familiarity when stimuli are “unitized”, or encoded as a single representation. Unitization generally …

Decision-centric resource-efficient semantic information management
… build a set of techniques as well as a holistic information management system that not only account for data level characteristics, but, more importantly, take advantage of the higher information semantic level features as well as the even higher level decision logic structures in achieving …

Is There Hebb Repetition Learning for Semantic Information?
… al., 2013) showing that repeating a sequence of information results in better serial recall accuracy relative to non-repeated sequences (i.e., the Hebb repetition effect, HRE). Additional information, other than exact item and order repetition, can produce HREs such as motor responses (Johnson et …

Learning Semantic Information from Multimodal Data using Deep Neural Networks
<p>During the last decades, most collective information has been digitized to form an immense database distributed across the Internet. This can also be referred to as Big data, a collection of data that is vast in volume and still growing with time. Nowadays, we can say that Big data is …

Eye movements and processing of semantic information in the parafovea during reading
When we read a text, we obtain information at different levels of representation from abstract symbols. A reader’s ultimate aim is the extraction of the meaning of the words and the text. The reserach of eye movements in reading covers a broad range of psychological systems, ranging from low-level …

A comparison of imaging modalities and decoding methods for detecting semantic information in the brain
Representation of semantic information enables us to engage with the world in a meaningful way – to comprehend and produce language, identify and use objects, and understand and participate in events that involve us. Our understanding of where in the brain semantic information is represented has …

Semantic structure of personal information
… decisions are earliest, followed by access to semantic information, followed by naming. To date, the stage involved in semantic decisions has received least attention. Thus, relatively little is known about how we store personal semantic information. More research into this stage is necessary …

Semantic and Phonological Influences on Memory, False Memory, and Reminding
… impact on the relative amounts of surface and semantic information that are encoded in memory, resulting in different patterns of memory errors at test. Experiment 3 shows that older adults are able to use these naturalistic strategies in the same way as younger adults, resulting in the same …

Extraction and Use of Structured Information in Full -Text Retrieval: A Case Study
This work contributes to information retrieval research by providing a more specific and accurate document content representation and consequently more effective full-text retrieval and by providing a better understanding of how structured semantic information can impact full-text retrieval …

Pragmatic referring functions as Montague semantic operators
… the thesis is defended that lexical semantics is not a subdomain of semantics, but rather a subdomain of pragmatics. That is, knowledge about the meaning of words is not part of one's knowledge of the language, but rather part of one's knowledge of the world. This distinction marks …

Using 3D Visual Data to Build a Semantic Map for Autonomous Localization
… who normally rely on conceptual knowledge or semantic contents of the environment. Therefore, semantic maps become necessary for building an effective human-robot interface. Although researchers from both robotics and computer vision domains have designed some promising systems, mapping with …

Sensitivity to (sub)lexical cues as a function of cognitive profile and language abilities
… and orthographic) with morphological, semantic, and lexico-semantic cues during written and spoken word processing, as evidenced by behavioural and MEG data. The first part of the thesis shows that the processing of visual words and pseudowords in English varies considerably between …

A Neurophysiological Investigation of Listening Effort in Normal Hearing Adults Using fNIRS and Pupillometry
… how effort might be alleviated with access to semantic information. To achieve this, I implemented a speech recognition task and manipulated the semantic content of the sentence (Predictability), spectral degradation (Speech Quality), and the way participants reported their response (Task …

A pragmatic account of control

The Effects of Focus During Sentence Comprehension
… word, enhances memory for particular types of information about the word, including its identity and its phonological and semantic characteristics. In each of four experiments, subjects read sentences that varied according to whether or not they placed a single, critical word (the prime) in …

Lifelong, Learning-Augmented Robot Navigation
… the maps robots can build with object-level semantic information. To do so, a robot must combine continuous geometric information about its trajectory and object locations with discrete semantic information about object classes. This problem is complicated by the fact that object detection …

Effects of efficient fronto-temporal circuitry on lexical ambiguity resolution: converging evidence from cross-age comparisons in eye-tracking and ERP data
… how younger and older adults use syntactic and semantic information to disambiguate noun/verb (NV) homographs (e.g., park). We find that young adults exhibit inflated first fixations to NV-homographs when only syntactic cues are available for disambiguation (i.e., in syntactic prose). This …

Interactive Pattern Recognition Strategies for Multimedia Document Analysis and Search
… can be modeled as interactive prediction of semantic information. As a result, we can broadly decompose research into this area into the three critical system components: Interaction Strategies, Search/Learning Strategies and Representation. This dissertation seeks to make contributions to …

Applying case based reasoning and structural similarity for effective retrieval of expert knowledge from software designs
