Angela Bonifati, Ugo Comignani, Emmanuel Coquery, Romuald Thion
2017 Proceedings of the 2017 ACM International Conference on Management of Data - SIGMOD '17  
To tackle the above problem, in this paper we set forth a novel approach for Interactive Mapping Specification (IMS) that bootstraps with exemplar tuples, corresponding to a limited number of tuples provided  ...  Since exemplar tuples are not universal by definition 1 , this mapping is far Figure 2 : Interactive mapping specification process. too constrained.  ...

New trends on exploratory methods for data analytics

Davide Mottin, Matteo Lissandrini, Yannis Velegrakis, Themis Palpanas
2017 Proceedings of the VLDB Endowment  
We show how different data types require different techniques, and present algorithms that are specifically designed for relational, textual, and graph data.  ...  In this tutorial, we present an excursus over the main methods for exploratory analysis, with a particular focus on examplebased methods.  ...  More specifically, exact algorithms when positive and negative tuples are provided mostly rely on satisfiability problems and are therefore hard to solve [35] .  ...

Contextual Geometric Structures: modeling the fundamental components of cultural behavior

Bradly Alicea
2012 Artificial Life 13  
The first is a set of discrete automata with a soft classificatory structure.  ...  Formal computational and algorithmic models of culture have focused on the inheritance of discrete cultural units, which can be hard to define and map to practical contexts.  ...  The second kernel design is a 5-tuple with a contextual anchor, and maps to the human gustatory system.  ...

Designing a BPEL Orchestration Engine Based on ReSpecT Tuple Centres

Michele Cabano, Enrico Denti, Alessandro Ricci, Mirko Viroli
2006 Electronical Notes in Theoretical Computer Science  
We present the design of a BPEL orchestration engine based on ReSpecT tuple centres, a coordination model extending Linda with the ability of declaratively programming the reactive behaviour of tuple spaces  ...  Architectural and linguistic aspects of our solution are discussed, focussing on how the syntax and semantics of BPEL have been mapped to tuple centres.  ...  Mapping BPEL onto ReSpecT In this section we describe the mapping of a BPEL orchestration server in ReSpecT tuple centres, both in terms of the representation of a BPEL specification and the WVM behaviour  ...

RAQ: Relationship-Aware Graph Querying in Large Networks [article]

Jithin Vachery, Akhil Arora, Sayan Ranu, Arnab Bhattacharya
2021 arXiv   pre-print
However, almost all existing techniques have tacitly ignored the presence of relationships in graphs, which are usually encoded through interactions between node and edge labels.  ...  Given two isomorphic subgraphs and , and an isomorphic mapping from the edges in to the edges in , the relationship-aware similarity (RAS) with respect to the mapping is the similarity between the mapped  ...  Given the exemplar edges, the common goal in this line of work is to identify subgraphs from the target graph that are connected by the same edge labels as expressed in the exemplars.  ...

Identifying the provenance of correlated anomalies

Dawood Tariq, Basim Baig, Ashish Gehani, Salman Mahmood, Rashid Tahir, Azeem Aqil, Fareed Zaffar
2011 Proceedings of the 2011 ACM Symposium on Applied Computing - SAC '11  
A key contribution is the design of an anomaly-provenance bridge that allows opaque digests of anomalies to be mapped back to their associated provenance.  ...  The more specific the logs, the more precise the analysis they allow. However, collecting detailed logs from across a distributed system can deluge the network fabric.  ...  We create a data provenance subsystem, and a bridge that allows a specific k-tuple to be mapped to its provenance, as depicted in Figure 2 .  ...

Unsupervised incremental learning for long-term autonomy

Lionel Ott, Fabio Ramos
2012 2012 IEEE International Conference on Robotics and Automation  
For each of these clusters, we obtain the probability of representing an obstacle through the interaction of the robot with the environment.  ...  The traversability property of an unseen object is also learnt without human supervision by the interaction between the robot and the environment.  ...  Each cluster is described by a 4-tuple (e i , n i , Σ i , t i ) where e i is the exemplar associated with the cluster, n i is the number of data points represented by the cluster, Σ i is the distortion  ...

ORCHESTRA: Rapid, Collaborative Sharing of Dynamic Data

Zachary G. Ives, Nitin Khandelwal, Aneesh Kapur, Murat Cakir
2005 Conference on Innovative Data Systems Research  
Conventional data integration techniques employ a "top-down" design philosophy, starting by assessing requirements and defining a global schema, and then mapping data sources to that schema.  ...  This works well if the problem domain is well-understood and relatively static, as with enterprise data.  ...  Consistency with Conflicting Data We begin by defining the specifics of the data model what it means for an instance to be consistent with a set of schema mappings.  ...

Varying variation: the effects of within- versus across-feature differences on relational category learning

Katherine A. Livins, Michael J. Spivey, Leonidas A. A. Doumas
2015 Frontiers in Psychology  
As a result, the way that they interact with feature variation is unclear.  ...  Learning of feature-based categories is known to interact with feature-variation in a variety of ways, depending on the type of variation (e.g., Markman and Maddox, 2003) .  ...  If DORA managed to map the current exemplar onto a previously seen exemplar, it "answered" with the category of the mapped previous exemplar.  ...

An approach to quantify integration quality using feedback on mapping results

Fernando R.S. Serrano, Alvaro A.A. Fernandes, Klitos Christodoulou
2019 International Journal of Web Information Systems  
Given a set of mappings and a set of workers of unknown trustworthiness, feedback instances are collected in the extents of the mappings that characterize the integration.  ...  pay-as-you-go approach to data integration aims to reduce the time and effort required by proposing a bootstrap phase in which algorithms, rather than experts, identify semantic correspondences and generate the mappings  ...  namely, I 1 , with mostly good mappings (specifically, ten good and three bad), and I 2 , with mostly bad mappings (specifically, ten bad and three good) [5] .  ...
