This paper proposes an algorithm that enables robots to efficiently learn human-centric models of their environment from natural language descriptions. Typical semantic mapping approaches augment metric maps with higher-level properties of the robot’s surroundings (e.g., place type, object locations), but do not use this information to improve the metric map. The novelty of our algorithm lies i...

Robotic systems should have a deep and specific knowledge about the environment they live in to properly interact with people and effectively perform the requested tasks. To this end, a suitable representation of the environment is needed, including both metric spatial information and semantic representations of locations and objects of interest. In this paper a representation of spatial and en...

This paper presents technology mapping techniques that optimize for average case delay of asynchronous burst-mode control circuits. First, the speci cation of the circuit is analyzed using stochastic techniques to determine the relative frequency of occurrence of each state transition. Then, subject to timing and area constraints, the technology mapper minimizes the sum of the cycle times of th...

ground penetrating radar (gpr) method as a high resolution non-destructive geophysical method is used for detection of shallow subsurface targets. this method is based on the transmission of electromagnetic waves inside the earth and recording the reflected waves from the subsurface. as the method uses high-frequency electromagnetic waves in the frequency ranges of 12.5 to 2500 mhz (called gpr ...

Semantic analyses of the PERFECT often defeat their own purpose: by restricting their attention to ‘real’ perfects (like the English one), they implicitly assume the PERFECT has predefined meanings and usages. We turn the tables and focus on form, using data extracted from multilingual parallel corpora to automatically generate semantic maps (Haspelmath, 1997) of the sequence ‘HAVE/BE + past pa...

This work combines semantic maps with hybrid control models, generating a direct link between action and environment models to produce a control policy for mobile manipulation in unstructured environments. First, we generate a semantic map for our environment and design a base model of robot action. Then, we combine this map and action model using the Motion Grammar Calculus to produce a combin...

MOTIVATION To evaluate how well current anatomical ontologies fit the way real-world users apply anatomy terms in their data annotations. METHODS Annotations from three diverse multi-species public-domain datasets provided a set of use cases for matching anatomical terms in two major anatomical ontologies (the Foundational Model of Anatomy and Uberon), using two lexical-matching applications ...
