NIF Webinar – April 6, 2010 / Topic: Preview of NIF 2.5 Release

Posted on March 30th, 2010 in News & Events, Webinar Announcement | No Comments »

The Neuroscience Information Framework (NIF) hosts Webinar series on topics focused on collaborating with NIF, getting involved in building the NIF vocabulary, using NIF portal resources, as well as other appropriate NIF topics.

Our next NIF Webinar is scheduled for April 6th, 2010. Please join Dr. Anita Bandrowski for an informational session on the new features offered in NIF 2.5.  Below is information on how to join the online meeting and accompanying teleconference.

Date and Time: Tuesday, April 6, 2010 • 11:00-12:00 PST
Topic: Preview of NIF 2.5 Release
Presenters: Dr. Anita Bandrowski

Dial-In (toll-free): 866-740-1260
Access Code: 8220739

NIF 2.5 will include new services, incorporate new features to the search interface, and solve known issues/bugs. Through this informational session, find out more about NIF cards, NIFSTD entity recognition, new literature, and improvements on search.  Learn more about the services such as the Ontology Access Service, SOLR Service, and  the varying API interfaces. New features to look forward to are Concept-based search through autoexpansion, MyNIF capabilities to save searches, highlighted search results according to a semantic category in the NIF ontologies, and many more. Known issues regarding the scroll bar, browser compatibility, and search box behavior have been resolved and we have even improved on performance and stability of NIF Literature and Pubmed Results.

We hope you can make it to this exciting session!

NIF Webinar – March 30, 2010 / Topic: NIF as a Multi-Model Semantic Information System Part 1: Relational, XML, RDF and OWL models

Our next NIF Webinar is scheduled for March 30th, 2010. Please join Dr. Amarnath Gupta  from the University of California, San Diego as he covers: NIF as a Multi-Model Semantic Information System–Part 1: Relational, XML, RDF and OWL models.  Below is information on how to join the online meeting and accompanying teleconference.

An important goal of the Neuroscience Information Framework (NIF) is to develop a data infrastructure that can ingest structured, semi-structured and unstructured information and perform semantic search over them. This is the first presentation of a series that will cover the NIF data infrastructure. In this presentation. we lay out the foundation of the different forms of data models that NIF is equipped to handle at this point. We specifically describe the relational, object relational, XML, RDF and OWL models of data and knowledge, and touch upon some of their variants. For these models, we present a simplified overview of their semantics, capabilities, and limitations. We conclude the presentation with an outlook of the specialized data models that NIF expects to handle in the future.

We hope you can make it!

A few months ago, ODIE 1.0 was quietly released on the NCBO GForge site. ODIE is an application that lets researchers (1) analyze text corpora using BioPortal ontologies to map text to BioPortal concepts, and (2) identify candidate concepts within text corpora that could be considered for addition to an existing ontology. The ODIE project has made some significant advances this year – including (1) complete redesign to use the UIMA platform, (2) integration of Mayo cTAKES pipeline into ODIE, (3) addition of a simple co-reference resolution algorithm as UIMA resource, and (4) addition of statistical as well as linguistic methods for discovering candidate concepts. In addition to the software, we’ve been working on developing co-reference corpora, and testing a variety of existing methods for ontology enrichment using domain experts and ontology developers as judges. This talk will demonstrate the latest release and will sample some of the year’s research project findings. Dr. Rebecca Crowley from the University of Pittsburgh School of Medicine, will preview the upcoming release of ODIE 1.1 which includes improved installation, visualization, placement of candidate concepts and export of proposals as OWL files.

We look forward to seeing you there.
