    Title:Scalable Querying of Semantic Web Data Models: Challenges and Opportunities

    Abstract: The Center for Transformational Innovations (CeTI), at EMC India COE has been chartered with looking at some of fundamental problems afflicting masses in emerging economies. Healthcare and education has come up as the two fundamental pillars on which we can deliver a wholesome human-like life to all citizens. The health of populations is a distinct key issue in public policy discourse in every mature society often determining the deployment of huge society. The first criteria for a just healthcare system is- universal access to an adequate level, and access without excessive burden. In most emerging economies meeting this first criteria itself has been and continuous to be a challenge. In this talk I will highlight the problems in existing Healthcare Systems, present the potential of bringing IT enabled solutions, share the data management, analytics and privacy issues that will arise and conclude with how we at CeTI are engaged in this space.

    Title:Massive Scale Collaborative Editing

    Abstract: Since the Web 2.0 era, the Internet is a huge content editing place in which users contribute to the content they browse. Users do not just edit the content but they collaborate on this content. Such shared content can be edited by thousands of people. However, current consistency maintenance algorithms seem not to be adapted to massive collaborative updating. Shared data is usually fragmented into smaller atomic elements that can only be added or removed. Coarse-grained data leads to the possibility of conflicting updates while fine-grained data requires more metadata. In this discussion we offer a solution for handling an adaptable granularity for shared data that overcomes the limitations of fixed-grained data approaches. Our approach defines data at a coarse granularity when it is created and refines its granularity only for facing possible conflicting updates on this data.

    Biography: Luc Andre is a 3rd year PH.D Student in Computer Science at Université de Lorraine, in France, and works at the Loria Lab which also partners with INRIA Research Center. His research focuses on algorithms for collaborative editing in the distributed environment.

    Title:Scalable Querying of Semantic Web Data Models: Challenges and Opportunities

    Abstract: Recent advancements in Semantic Web publishing technologies are ushering in the era of "big Semantic Web data". We now have a rapidly growing number of publicly available Semantic Web datasets spanning a variety of domains. Attempting to harness the collective knowledge represented in combinations of these datasets, quickly gives rise to a "big and heterogeneous data" problem. Although, there are numerous research activities now focused on "big data", many of them focus on data that is fairly homogeneous and either completely structured or completely unstructured. However, Semantic Web data models impose very few constraints on structure compared to relational models, leading to graph-like or semi(structured) nature. Further, Semantic Web data collections often contain data expressed using multiple vocabularies or schemas requiring processing that involves reasoning about equivalences that are not explicitly stated. These requirements lead to workloads that do not match assumptions made by traditional relational query optimization techniques. Unfortunately, many existing Semantic Web data query processing techniques still rely on relational-like query optimization techniques and, the impact of this mismatch is much more palpable at large scales. The use of cloud computing platforms to support elastic scaling requirements adds yet another dimension of challenges because several key assumptions underlying traditional query optimization techniques do not transfer to popular platforms like Google's MapReduce. In this talk, I will present an overview of the efforts being undertaken by the Semantic Computing Research Lab at North Carolina State University to address some of these challenges and highlight some open research opportunities.

    Biography: Kemafor Anyanwu is an Assistant Professor of Computer Science and director of the Semantic Computing Research Lab at North Carolina State University.

    Title:The trouble with first impressions: How contextualized instantiations hinder transfer of mathematical knowledge

    Abstract: It has been suggested by philosophers and cognitive scientists that mathematical cognition is embodied in the sense that it is grounded in human perception and action. Embodied accounts of cognition often posit that cognition is situated in real-world experiences, and these accounts are frequently extended to advocate that mathematics teaching should also be grounded in human experience. According to such as a position, presenting mathematical concepts through real-world contexts can tap a learner's prior knowledge and facilitate learning. However, a primary goal of learning mathematics is the ability to apply this knowledge to novel situations. Therefore effective teaching should promote not only initial learning but also subsequent transfer of mathematical knowledge. Real-world instantiations of mathematics are typically perceptually and conceptually rich, conveying considerably more extraneous information than their more symbolic counterparts. This extraneous information may remain associated with the learner's interpretation of the mathematical structure consequently constraining the applicability of the mathematical knowledge. In this talk, I will present evidence that acquiring mathematical concepts through contextualized, real-world instantiations can hinder subsequent transfer of knowledge in comparison to acquiring mathematics through more symbolic instantiations. These findings have important implications for the teaching of mathematics because they suggest that while some contextualized instantiations of mathematics may be intuitively appealing and offer a leg-up in the learning process, they may hinder subsequent transfer. Symbolic representations of mathematics may sometimes be more difficult to initially learn, but once acquired they are powerful in the sense that they enable the learner to recognize mathematical structures in realworld situations.

    Biography: Jennifer Kaminski holds bachelors and masters degrees in mathematics and a doctorate in mathematics education with a focus on psychology and cognitive science. She has worked in the field of actuarial consulting and also taught undergraduate mathematics. Currently, she is a research scientist at the Ohio State University Center for Cognitive Science and Department of Psychology. The primary focus of her research has been the acquisition and application of mathematical structures.

    Title:Mathematical Reasoning as a Literally Physical Symbol System

    Abstract: Much of the power of mathematics comes from its generality and ability to unify prime face dissimilar domains. By one account, analytic thought in math and science requires developing deep construals of phenomena that run counter to untutored perceptions. This approach draws an opposition between superficial perception and principled understanding. In this talk, I advocate the converse strategy of grounding mathematical reasoning in perception and action. I will describe empirical evidence for perceptual changes that accompany learning in mathematics. In arithmetic and algebraic reasoning, we find that proficiency involves executing spatially explicit transformations to notational elements. People learn to attend mathematical operations in the order in which they should be executed, and the extent to which students employ their perceptual attention in this manner is positively correlated with their mathematical experience. People produce mathematical notations that they are good at reading. Perceptual and attentional processes are tailored to fit mathematical requirements. Thus, for reasoning in mathematics, relatively sophisticated performance can be achieved not only by ignoring perceptual features in favor of deep conceptual features, but also by adapting perceptual processing so as to conform with and support formally sanctioned responses. These "Rigged Up Perceptual Systems" (RUPS) offer a promising strategy for achieving educational reform. Based on the theoretical foundation of RUPS, we have designed and implemented a virtual, interactive sandbox for students to explore algebra. At the end of this talk, I will describe experiments that explore the use of this system by 11-19 year old students.

    Title: Social Life Networks
    Abstract: We are living in an age of social media that provides numerous channels for digital expression and sharing almost instantaneously in any part of the world. By bringing different media as well as modes of distribution -- focused, narrowcast, and broadcast -- social networks (SN) have revolutionized communication among people. I believe that by using the enormous reach of mobile phones equipped with myriad sensors,the next generation of social networks can be designed not only to connect people with other people, but also to connect people with essential life resources. I call these networks Social Life Networks (SLN) and believe that this is the right time to focus efforts to discover and develop technology and infrastructure to design and build these networks. I will discuss my approach to building SLNs and will identify challenges that must be addressed to make SLNs practical. I will also discuss their implications for masses in emerging countries, the Middle of the Pyramid, and the technology development in making that practical.

    Title: Social tagging networks: Cohesiveness and Dynamics
    Abstract: This talk proposes an approach to studying the structure and dynamics of large cohesive groups of tags in online social networks. Given a tag co-occurrence graph defined over a particular time span, the cohesive subgroups of tags are modeled using the graph theoretic concept of a k-plex, which was originally introduced in the social network analysis literature. This model can be thought of as a relaxed, more practical version of the popular clique model that is obtained by allowing a predetermined (and typically small) number k of non-neighbors for each vertex within the group. Intuitively, a maximum k-plex in the graph should be related to one of the most popular topics discussed in the network, and the size of a maximum k-plex can serve as a reasonable global measure of cohesiveness of the network. Moreover, study of the structure and dynamics of changes in the maximum k-plex of the tag co-occurrence graph of the same social network over time can be used to deduce some interesting information about the underlying social network. We illustrate the proposed method on a large set of dynamic data extracted from Delicious social bookmarking community.

    Title: Weighted PageRank for heterogeneous scholarly networks
    Abstract: Large scale weighted PageRank can be calculated for heterogeneous citation network, author-citation networks and journal citation networks. Weights are considered as citation time, self-citation, journal impact factors. Weighted PR ranks have been compared with normal citation rank. This method can be easily extended to other heterogeneous networks. Potential interesting issues are dangling nodes, heuristic parameter settings.

    Ontology alignment determines the semantic heterogeneity between two or more domain specifications by considering their associated concepts. Our approach considers name, structural and content matching techniques for aligning ontologies. Together with UMN, we justify the conceptual validity of our ontology alignment technique with a series of experimental results that demonstrate the efficacy and utility of our algorithms on a wide-variety of authentic GIS data including multi-jurisdictions.

    The second part of the presentation deals with scalable storage and retrieval of large RDF graph. Currently available semantic web frameworks do not work well for this retrieval task. In this talk, we describe a framework that we built using Hadoop to store and retrieve large number of RDF triples. We describe a scheme to store RDF data in Hadoop Distributed File System. We also describe our algorithms to generate the best possible query plan to answer a SPARQL (SPARQL Protocol and RDF Query Language) query based on a cost model. We use Hadoop's MapReduce framework to actually answer the queries. Our results show that we can store large RDF graphs in Hadoop clusters built with cheap commodity class hardware. We conclude that our framework is scalable and efficient and can handle large amounts of RDF data.

    Title: Beyond Search: 5 steps to insight
    Abstract: Evidence points to the reason why blind application of Web search to enterprises produces undesirable outcomes. First, enterprises are lagging the Web in achieving richly connected information. Second, the level of specificity of meaning and the depth of modeling expected by enterprise users are both higher than by consumers. In this talk, I will show the first houses we have built on the semantic foundations for enterprise search we laid in our previous work.

    The talk will begin with an analysis of how people, processes and infrastructure are currently deployed in information-rich businesses in order to make sense of tens of petabytes of open and proprietary information. I will discuss why existing architectures—especially, their implied cost and delay structures—do not scale to the demands and opportunities thrown open by new economic and business models aroundormation. I will then argue that in order to architect for exabytes and beyond, businesses need to make a switch to architecting their information services around an economy of plenty (away from architecting around the economy of dearth that gave us search).

    In the process, we will turn on its head the very problem that motivates search technology, for instance, asking and answering the fundamental question: Is it not already too late if you have to look for something? I will present architectures for delivery and sense-making. At the heart of these systems lies an engine that shortens the path from “Got it.â€Got it!†to insight. We will show how to couple this engine with context-mapping technologies in order to move beyond searching for documents to having the right insights delivered into the right heads at the right time. The talk concludes with blueprints from information-heavy industries, such as financial and legal services, which I expect will become widely adopted in the near future.

    Title: Toward Visual Knowledge Discovery and Analytics
    Abstract: Knowledge discovery and data mining is a process whose goal is to extract interpretable and actionable information from complex (potentially large) data. Visualization can play an important role in this exploratory process. Indeed, a number of important scientific discoveries have ultimately relied on visual confirmation from Galileo seeing the moons of Jupiter to Gerd Binnig and Heinrich Rohrer seeing atoms on a surface. Visualization can also play an important role in understanding the nature of a problem domain and subsequently the patterns governing the underlying solution space. In this talk I will talk about our vision on the roles visualization can play in the knowledge discovery process. Specifically we will examine the use of visualization:

    1. As a mechanism to facilitate exploration of complex datasets.
    2. As a means to validate and confirm results obtained from the discovery process.
    3. As an approach to understand and lend transparency to the discovery process.

    In each case I will attempt to illustrate the roles in the context of specific end applications drawn from the domains of physics of materials, bioinformatics, social network analysis and clinical diagnosis of eye disease. No prior knowledge of data mining, knowledge discovery, visualization or any of these application domains will be assumed.

    Title: Extracting Semantic Predications from Biomedical Text
    Abstract: SemRep is a symbolic natural language processing system that identifies semantic predications in biomedical text. For example, "Acetylcholine STIMULATES Nitric Oxide" is extracted from the sentence "In humans, ACh evoked a dose-dependent increase of NO levels in exhaled air." The system is linguistically based and depends on domain knowledge in the Unified Medical Language System. Underspecified interpretation for a range of syntactic structures is provided, rather than detailed representation for a limited number of phenomena. Thirty core predications in clinical medicine, genetic etiology of disease, pharmacogenomics, and molecular biology are retrieved. Several evaluations report precision around 75% and recall near 65% (both lower for molecular biology). SemRep predications have been exploited for text mining applications in genetic etiology of disease, automatic summarization, literature-based discovery, and enhanced information retrieval.
