Many researchers have used lexical networks and ontologies to mitigate synonymy and polysemy problems in Question Answering (QA), systems coupled with taggers, query classifiers, and answer extractors in complex and ad-hoc ways. We seek to make QA systems reproducible with shared and modest human effort, carefully separating knowledge from algorithms. To(More)
•Matches based on signal subsequences of any length, although they are typically longer than single characters or phonemes (e.g. polygrams). •Accommodates common distortions in cameraand tablet-based OCR (stretching, contraction) and speech (time-warping). •Does not depend on the specific medium, feature set, and vocabulary. •No training, only a reference(More)
Letter-polygram based Symbolic Indirect Correlation is a new method that offers significant advantages for ordered unsegmented signals. However, its application to on -line, cursive handwriting requires solving several difficult problems. (1) Reference strings of words must satisfy certa in uniformity properties on their lexical match with the lexicon of(More)
Symbolic indirect correlation (SIC) is a new approach for bringing lexical context into the recognition of unsegmented signals that represent words or phrases in printed or spoken form. One way of viewing the SIC problem is to find the correspondence, if one exists, between two bipartite graphs, one representing the matching of the two lexical strings and(More)
Symbolic Indirect Correlation (SIC) is a nonparametric method that offers significant advantages for recognition of ordered unsegmented signals. A previously introduced formulation of SIC based on subgraph-isomorphism requires very large reference sets in the presence of noise. In this paper, we seek to address this issue by formulating SIC classification(More)
This paper describes the design and simulation of a probe fed PLANAR INVERTED F ANTENNA (PIFA), operating at 2.4 GHz ISM band frequency; using HFSS simulator. Parameters like height of the patch from the ground, shorting plate dimensions and feed position are optimized to obtain a high gain PIFA. Bandwidth of the designed antenna is 281 MHz and gain is(More)
metabolic stress responses and electrolyte shift during perioperative period. Overall, BWS with AV canal defect requires management of airway, PAP in a balanced way with a judicious use of inotropes, sedation and an aggressive monitoring of arterial blood gas, blood sugar, and electrolytes in the entire perioperative period. The skills of the(More)
BACKGROUND It is a common practice to perform inhalational induction with sevoflurane followed by intravenous cannulation in children. However, there is little information regarding the time at which the intravenous cannulation can be attempted safely after sevoflurane induction. AIM To determine the optimal time for safe intravenous cannulation in(More)
