Next Steps

Arity Corporation

Arity Corporation leads the way in the use of Linked Data and Social Learning for Performance Support.

We build life-preservers for individuals and organizations that are drowning in data and tools. We are passionate about facilitating innovation, insight, and collaboration to enable people to solve complex problems and create breakthrough solutions.

To achieve this, we have solved a great many problems in the understanding of content and context of knowledge within documents and as expressed by people's goals and workflow needs while performing research. We are expert at natural language understanding, knowledge representation, recommendation, and reasoning technologies.

LexiLink

LexiLink™: The Vocabulary and Ontology Management Tool and the LexiLink tools are a part of Arity's Semantic Studio.

LexiLink™ is an ideal application for building, curating and managing multiple lexicons and ontologies in one enterprise-wide Web-based application. Oftentimes, source lexicons are outside your control. The magic of LexiLink is this: When you assemble a new lexicon that draws relevant parts from existing lexicons and ontologies to meet a particular need, LexiLink manages the provenance of concepts and attributes and alerts you to specific changes in source lexicons that are relevant to you. This allows you to quickly absorb changes and new versions directly into your new lexicon.

In Brief

With LexiLink™, enterprise-wide management of multiple lexicons and ontologies sets the stage for conducting scientific investigations and accelerating scholarship.

LexiLink is the premiere tool for organizing complex knowledge bases through collaborative curation and alignment of multiple lexicons and ontologies. Based on Arity’s innovative data storage and interpretation architecture, LexiLink offers faster and smarter searching, matching, classification, and integrity verification. LexiLink automatically fixes logic errors in imported data (such as parent relationships to ancestors) – a feature not available in any other lexicon manager. And, LexiLink comes with Web service API’s to further exploit the power of the poly-ontology. With LexiLink, users can view terms with full synonym expansion and annotate entries, establish links between terms, and perform fast, powerful searches across lexicons.

LexiLink enables productivity by providing curators with all the tools they need to solve technical language issues. LexiLink can import many of the widely used lexicons and ontologies in the biomedical field such as UMLS extracts, MeSH, GO, GOA, ChEBI and non-biomedical such as WordNet. LexiLink can manage vocabularies with millions of entries. It’s easy to incorporate existing vocabularies as well as create new ones within LexiLink. With its sophisticated API, tools, interfaces and services LexiLink supports:

Different levels of abstraction for different audiences;
Unlimited cross references between multiple lexicons;
Alerts when any one of a set of linked concepts is changed;
Flexible import/export features (for example, exporting data to text mining applications).

LexiLink Tools

LexiLink also includes a set of tools that are particularly convenient to high-throughput curation tasks. These tools enable a group of people with differing skills and responsibilities to adapt and improve a set of lexicons and ontologies for any application area. Below is a screenshot of one of these tools displaying a particular concept.

Suggestions

LexiLink also incorporates automatically discovered synonyms and new concepts arising from Semantic Studio's analysis of content. Much more than typical "text analytics", the suggestions presented by Semantic Studio are derived from a sophisticated linguistic and conceptual analysis of content.
