BeeSpace Navigator

BeeSpace Navigator automates extraction and semantic indexing of gene function information from biological literature to support literature-based gene function classification.

Key Features:

• Automated curation: Automates extraction of gene function information from biological literature that would otherwise be manually curated.
• Semantic indexing and conceptual spaces: Performs semantic indexing within conceptual spaces to enable task-specific literature curation and concept retrieval.
• Analysis of gene lists from expression experiments: Analyzes literature containing gene lists derived from expression experiments and extracts concepts computationally equivalent to classifications such as the Gene Ontology.
• Summarization, phrase extraction, and statistical indexing: Extracts sentences summarizing individual gene functions, performs statistical frequency analysis of literature phrase extraction, and builds offline semantic indexes to support gene function services and generate results analogous to model organism database entries.

Scientific Applications:

• Literature-based gene function classification: Supports automated classification of gene functions using evidence extracted from biological texts.
• Generation of database-style summaries: Produces sentence-level summaries of gene function comparable to entries in model organism databases.
• Interpretation of expression-derived gene lists: Facilitates interpretation of gene lists from expression experiments by extracting discriminating functional concepts.
• Support for genomics and bioinformatics research: Provides computational evidence and semantic indexes useful in genomics, molecular biology, and bioinformatics studies.

Methodology:

Automated curation of biological literature, semantic indexing within conceptual spaces, literature phrase extraction with statistical frequency analysis, extraction of sentences summarizing gene functions, creation of offline semantic indexes, and mapping of extracted concepts to classifications analogous to the Gene Ontology; analysis of gene lists from expression experiments is supported.
