Towards Sparsified Federated Neuroimaging Models via Weight Pruning
Federated training of large deep neural networks can often be restrictive due to the increasing costs of communicating the updates with increasing model sizes. Various model pruning techniques have been design...

NSEEN: Neural Semantic Embedding for Entity Normalization
Much of human knowledge is encoded in text, available in scientific publications, books, and the web. Given the rapid growth of these resources, we need automated methods to extract such knowledge into machine...

Abstract Meaning Representations as Linked Data
The complex relationship between natural language and formal semantic representations can be investigated by the development of large, semantically-annotated corpora. The “Abstract Meaning Representation” (AMR...

Leveraging Linked Data to Discover Semantic Relations Within Data Sources
Map** data to a shared domain ontology is a key step in publishing semantic content on the Web. Most of the work on automatically map** structured and semi-structured sources to ontologies focuses on seman...

Finding Concept Coverings in Aligning Ontologies of Linked Data
Despite the recent growth in the size of the Linked Data Cloud, the absence of links between the vocabularies of the sources has resulted in heterogenous schemas. Our previous work tried to find conceptual map...

A Graph-Based Approach to Learn Semantic Descriptions of Data Sources
Semantic models of data sources and services provide support to automate many tasks such as source discovery, data integration, and service composition, but writing these semantic descriptions by hand is a ted...

Semi-automatically Map** Structured Sources into the Semantic Web
Linked data continues to grow at a rapid rate, but a limitation of a lot of the data that is being published is the lack of a semantic description. There are tools, such as D2R, that allow a user to quickly co...

Discovering Concept Coverings in Ontologies of Linked Data Sources
Despite the increase in the number of linked instances in the Linked Data Cloud in recent times, the absence of links at the concept level has resulted in heterogenous schemas, challenging the interoperability...

Rapidly Integrating Services into the Linked Data Cloud
The amount of data available in the Linked Data cloud continues to grow. Yet, few services consume and produce linked data. There is recent work that allows a user to define a linked service from an online ser...

Linking and Building Ontologies of Linked Data
The Web of Linked Data is characterized by linking structured data from different sources using equivalence statements, such as owl:sameAs, as well as other types of linked properties. The ontologies behind th...

Automatically Constructing Semantic Web Services from Online Sources
The work on integrating sources and services in the Semantic Web assumes that the data is either already represented in RDF or OWL or is available through a Semantic Web Service. In practice, there is a tremen...

Automatically Composing Data Workflows with Relational Descriptions and Shim Services
Many scientific problems can be represented as computational workflows of operations that access remote data, integrate heterogeneous data, and analyze and derive new data. Even when the data access and proces...

Integration of Heterogeneous Knowledge Sources in the CALO Query Manager
We report on our effort to build a real system for integrating heterogeneous knowledge sources with different query answering and reasoning capabilities. We are conducting this work in the context of CALO (Cog...
