Natural language and spatial reasoning
… domains: finding video clips that match a spatial language description such as "People walking through the kitchen and then going to the dining room" and following natural language commands such as "Go down the hall towards the fireplace in the living room." Understanding spatial language …

Qualitative Spatial Reasoning With Super-Intuitionistic Logics
… that may benefit from the automation of spatial reasoning, notably in geographic information systems and in graphics. Reasoning about topology is known to be intrinsically complex, and difficult to be dealt with by a machine. Qualitative formalisms for spatial reasoning, region-based …

Generating Relation Algebras for Qualitative Spatial Reasoning
… rooms should be close to each other. Qualitative spatial reasoning as an area of artificial intelligence tries to develop a theory of space based on similar notions. In formal ontology and in ontological computer science, mereotopology is a first-order theory, embodying mereological and …

Modal and Relevance Logics for Qualitative Spatial Reasoning
Qualitative Spatial Reasoning (QSR) is an alternative technique to represent spatial relations without using numbers. Regions and their relationships are used as qualitative terms. Mostly peer qualitative spatial reasonings has two aspect: (a) the first aspect is based on inclusion and it focuses …

Propositional and activity monitoring using qualitative spatial reasoning
… semantic relationships known as qualitative spatial relations (QSRs). These primitives are then combined to estimate the state of the world in the same language used by most planners, planning domain definition language (PDDL) propositions. Both the primitives and propositions are combined to …

Evaluating Shadowspect as a Potential Measure of Spatial Reasoning
Spatial reasoning allows individuals to conceive and manipulate mental representations of objects in space and is an essential process in countless daily activities (Clements & Battista, 1992). The online geometric puzzle game Shadowspect was created as a tool to evaluate players' spatial reasoning …

Spatial reasoning for computer aided design, manufacturing and process planning
Reasoning about geometric relations and construction of scenes satisfying them are critically important tasks in computer-aided design, manufacturing and process planning. This work addresses these tasks by producing a centralized server for static and dynamic geometric reasoning. Static reasoning …

Spatial reasoning about remotely sensed data for drainage network mapping
In order to extract a drainage network from a LANDSAT scene of mountainous terrain, it is necessary to use an illumination model to separate the reflectance information from the topographic information in the LANDSAT data. From the reflectance information, visible stream segments can be detected. …

Characterizing the use of spatial reasoning skills in introductory chemistry instructor's materials
Undergraduate chemistry students require spatial reasoning skills to interpret static images of molecular and electronic structure, particularly when encountering new molecular concepts. Prior literature has established that spatial reasoning is an important indicator for success in chemistry, yet …

Preschoolers’ Use of Verbal and Musical Strategies for Solving a Spatial Reasoning Task
<p>Spatial reasoning is the ability to visualize and interact with one’s three-dimensional environment. A spatial problem that is particularly challenging for young children is the tube task, developed by Hood in 1995. Children are presented with an apparatus that consists of a large frame with …

Evaluation and Enhancement of Qualitative Spatial Reasoning in LLMs via Symbolic Fine-Tuning
… σε σύγχρονα Μοντέλα Μεγάλης Συλλογιστικής (Large Reasoning Models- LRMs). Παρά την εντυπωσιακή πρόοδο των Μεγάλων Γλωσσικών Μοντέλων (LLMs), η ικανότητά τους να εκτελούν τυπική συμβολική λογική σε αυστηρά γεωχωρικά πλαίσια παραμένει μια σημαντική πρόκληση. Η έρευνα επικεντρώνεται στο μοντέλο …

Effects Of A Mathematics Curriculum Rich In Spatial Reasoning Activities On Fifth Grade Students' Abilities To Spatially Reason: An Action Research Project
… to describe the effect of a curriculum rich in spatial reasoning activities and experiences on the ability of my fifth grade students to spatially reason. The study was conducted to examine 1) the effects of my practice of incorporating spatial reasoning lessons and activities in my fifth-grade …

Supporting spatial skill learning with gesture-based embodied interaction
Prior research has revealed that spatial abilities are crucial for STEM achievement and attainment. The connection between the digital and physical worlds provided by embodied interaction has been shown to enhance performance and engagement in educational contexts. Spatial reasoning is a domain …

Virginia's Foundation Blocks for Early Learning: Interpretation and Implementation by Practitioners
… scaffolded instruction, emergent literacy, and spatial reasoning. The Foundation Blocks were examined to determine how they were interpreted and implemented by preschool classroom teachers. Using a case-study format, four volunteer teachers participated in three days of classroom observations, …

Working memory and human reasoning : an individual differences approach
… memory and syllogistic and five-ten-n series spatial inference. A secondary aim was to replicate the findings of Shah and Miyake (1996) who suggested the use of separate central resources of working memory for spatial and verbal ability. The correlational analysis showed that the complex …

VRCC-3D+: Qualitative spatial and temporal reasoning in 3 dimensions
<p>"Qualitative Spatial Reasoning (QSR) has varying applications in Geographic Information Systems (GIS), visual programming language semantics, and digital image analysis. Systems for spatial reasoning over a set of objects have evolved in both expressive power and complexity, but implementations …

Video as the Language of Embodied Intelligence
… perception, grounding, and control. For example, spatial reasoning—a simple yet indispensable capability for robots—reveals one of such shortcoming clearly: multimodal LLMs often fail even basic spatial perception tasks like estimating distances. This thesis begins by examining these failures …

Discrimination of water from shadow regions on radar imagery using computer vision techniques
… algorithm to do the low level labeling and a spatial reasoning procedure based on a relational model to perform the high level interpretation. The experimental results obtained from the SAR images are presented to illustrate the performance of this system.
