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.

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:The IBM PaaS: from inception in research project Altocumulus to customers as IBM Pure Application Systems
Abstract:
In this talk I will describe the evolution of the IBM Platform-as-a-Service or IBM PureApplication System, a member of the IBM PureSystems [1] family of PaaS and private IaaS cloud products and services [2]. Our journey will take us from a little known cloud research project (IBM Altocumulus [3][4]) to its current manifestation as IBM PureApplication System and the many forms it took in between. I will try to draw some lessons learned in the three year journey, highlighting how IBM Research does "research" (from my opinion) as well as what works well in this type of industry research setting and what does not.

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.
