System detects, translates sarcasm on social media

"There are a lot of systems designed to identify sarcasm, but this is the first that is able to interpret sarcasm in written text," said Peled. "We hope in the future, it will help people with autism and Asperger's, who have difficulty interpreting sarcasm, irony and humor."
Based on machine translation, the new system turns sarcastic sentences into honest (non-sarcastic) ones. It will, for example, turn a sarcastic sentence such as, "The new 'Fast and Furious' movie is awesome. #sarcasm" into the honest sentence, "The new Fast and Furious movie is terrible."
Despite the vast development in this field, and the successes of sentiment analysis applications on "social media intelligence," existing applications do not know how to interpret sarcasm, where the writer writes the opposite of what (s)he actually means.
In order to teach the system to produce accurate interpretations, the researchers compiled a database of 3,000 sarcastic tweets that were tagged with #sarcasm, where each tweet was interpreted into a non-sarcastic expression by five human experts. In addition, the system was trained to identify words with strong sarcastic sentiments -- for example, the word "best" in the tweet, "best day ever" -- and to replace them with strong words that reveal the true meaning of the text. The system was examined by a number of (human) judges, who gave its interpretations high scores of fluency and adequacy, agreeing that in most cases it produced a semantically and linguistically correct sentence.
Automatic identification and analysis of sentiment in text is a very complex challenge being explored by many researchers around the world because of its commercial potential and scientific importance. Sentiment identification could be used in social, commercial, and other applications to improve communication between people and computers, and between social media users.

Exposing newborn mice to general anesthetic disrupts brain development

The researchers, based in The Johns Hopkins University School of Medicine , Baltimore, focused on the hippocampus, a brain region that is critical for learning and memory. The hippocampus contains a large number of neurons that develop in the early postnatal period, and which might thus vulnerable be to perturbation by anesthetic exposure. 15 day-old mice were exposed to clinically relevant doses of isoflurane and the effects on the subsequent development of the hippocampus were recorded. The structures of one class of neurons (the dentate gyrus granule cells) were found to be substantially altered. Specifically, the branches or dendrites of the neurons were almost twice the length of those in untreated animals, suggesting that the anesthetic caused an abnormal acceleration in their growth. In addition they saw a significant reduction in the number of mature dendritic spines -- structures on the dendrites where synapses are found. To see whether these changes were associated wit...

Structural insights into the modulation of synaptic adhesion by MDGA for synaptogenesis

In a recent issue of  Neuron , published on June 21, 2017, a research team led by Professor Ho Min Kim at the Graduate School of Medical Science and Engineering of KAIST reported the three-dimensional structure of MDGA1/Neuroligin-2 complex and mechanistic insights into how MDGAs negatively modulate synapse development governed by Neurexins/Neuroligins trans -synaptic adhesion complex. MDGA1 consists of six Ig-like domains, fibronectin type III repeat domain, and MAM domain . The crystal structure of MDGA1/Neuroligin-2 complex reveals that they form the 2:2 hetero-tetrameric complex and only the Ig1-Ig2 domains of MDGA1 are involved in interactions with Neuroligin-2. The structural comparison between the MDGA1/Neuroligin-2 and Neurexin-1β/Neuroligin-1 complexes intriguingly indicates that the Neuroligin-2 region binding to MDGA1 largely overlaps with that of Neurexin-1β, but the interaction interface of the MDGA1/Neuroligin-2 complex is much larger than that of the Neurexin-1β...

Mice provide insight into genetics of autism spectrum disorders

Taking advantage of advances in genetic technologies, researchers led by Alex Nord, assistant professor of neurobiology, physiology and behavior with the Center for Neuroscience at the University of California, Davis, are gaining a better understanding of the role played by a specific gene involved in autism. The collaborative work appears June 26 in the journal  Nature Neuroscience . "For years, the targets of drug discovery and treatment have been based on an unknown black box of what's happening in the brain," said Nord. "Now, using genetic approaches to study the impact of specific mutations found in cases, we're trying to build a cohesive model that links genetic control of brain development with behavior and brain function." The Nord laboratory studies how the genome encodes brain development and function, with a particular interest in understanding the genetic basis of neurological disorders. Mouse brain models There is no known specific g...
