Hi, how can I help you?: Automating enterprise IT support help desks
Question answering is one of the primary challenges of natural language
understanding. In realizing such a system, providing complex long answers to
questions is a challenging task as opposed to factoid answering as the former
needs context disambiguation. The different methods explored in the literature
can be broadly classified into three categories namely: 1) classification
based, 2) knowledge graph based and 3) retrieval based. Individually, none of
them address the need of an enterprise wide assistance system for an IT support
and maintenance domain. In this domain the variance of answers is large ranging
from factoid to structured operating procedures; the knowledge is present
across heterogeneous data sources like application specific documentation,
ticket management systems and any single technique for a general purpose
assistance is unable to scale for such a landscape. To address this, we have
built a cognitive platform with capabilities adopted for this domain. Further,
we have built a general purpose question answering system leveraging the
platform that can be instantiated for multiple products, technologies in the
support domain. The system uses a novel hybrid answering model that
orchestrates across a deep learning classifier, a knowledge graph based context
disambiguation module and a sophisticated bag-of-words search system. This
orchestration performs context switching for a provided question and also does
a smooth hand-off of the question to a human expert if none of the automated
techniques can provide a confident answer. This system has been deployed across
675 internal enterprise IT support and maintenance projects.Comment: To appear in IAAI 201
Role of sudarshan kriya and pranayam on lipid profile and blood cell parameters during exam stress: A randomized controlled trial
Background: Yoga is a science practiced in India over thousands of years. It produces constituent physiological changes and has sound scientific basis.
Aim: Since exam stress modifies lipid profile and hematological parameters, we conducted an investigation on the effect of sudarshan kriya (SK and P) program on these parameters.
Materials and Methods: Blood samples of 43 engineering students were collected at four intervals namely baseline (BL), exam stress (ES), three and six weeks practice of SK and P during exam stress. Lipid profile and hematological parameters were measured at all four intervals.
Results: ES elevated total cholesterol (TC), triglycerides (TGL) and very low density lipoprotein (VLDL) levels. Hematological parameters affected by ES included neutrophil, lymphocytes, platelet count, packed cell volume (PCV) and mean cell volume (MCV). Three and six weeks practice of SK and P reduced the elevated lipid profile, hematological parameters and improved lymphocyte levels.
Conclusion: Our study indicates that SK and P practice has the potential to overcome ES by improving lipid profile and hematological parameters
Design, synthesis and metal sensing studies of ether-linked bis-triazole derivatives
Ether-linked-bis-triazole derivatives have been synthesized by (CuAAC) "Click" reaction and well characterized by NMR spectroscopy, mass spectrometry, and elemental analysis. Application of these materials in the field of sensors has also been demonstrated using various spectroscopic techniques. The interaction of the compound with Hg2+ was further confirmed by computational studies
An easy access to novel sugar-based spirooxindole-pyrrolidines or -pyrrolizidines through [3+2] cycloaddition of azomethine ylides
An efficient one-pot synthesis of a library of novel sugar-based spirooxindole-pyrrolidines or -pyrrolizidines has been accomplished by [3+2] cycloaddition. This method utilizes an azomethine ylide derived from isatin and sarcosine or l-proline with an α,β-unsaturated β-C-glycosidic ketone as the dipolarophile. All these sugar-based heterocyclics were characterized by NMR (1H and 13C), HPLC, and elemental analysi
Agent Assist: Automating Enterprise IT Support Help Desks
In this paper, we present Agent Assist, a virtual assistant which helps IT support staff to resolve tickets faster. It is essentially a conversation system which provides procedural and often complex answers to queries. This system can ingest knowledge from various sources like application documentation, ticket management systems and knowledge transfer video recordings. It uses an ensemble of techniques like question classification, knowledge graph based disambiguation, information retrieval, etc., to provide quick and relevant solutions to problems from various technical domains and is currently being used in more than 650 projects within IBM
