Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Synthetic Biology

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Schemata

Schemata

A schema is a mental construct that organizes related concepts, allowing the brain to process information efficiently. Upon activation, schemata facilitate assumptions about people or objects.
Two types of schemata are:

Schemas

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Anatomical Terminology

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

What is Organic Chemistry?

What is Organic Chemistry?

Organic chemistry is the study of compounds of carbon called organic compounds. Organic compounds either originate from living organisms or are synthesized by chemists. A defining trait of these compounds is the presence of carbon as the principal element, which is bonded to other carbon atoms and other elements such as hydrogen, oxygen, nitrogen, and sulfur. The existence of a wide array of organic molecules is a consequence of carbon atoms’ ability to form up to four strong bonds to other...

Area of Science:

Biomedical Informatics
Semantic Web Technologies
Scientific Literature Analysis

Background:

A significant gap exists between available biomedical ontologies and their integration with scientific literature.
Researchers need better ways to connect formal ontologies with the natural language of published papers.

Purpose of the Study:

To develop an open, shareable structure, the Annotation Ontology (AO), for dynamic integration of biomedical ontologies with scientific documents.
To bridge the gap between formal ontologies and the scientific literature, enabling direct application of ontologies to emerging research.

Main Methods:

Elicited requirements through analysis of integration needs in biomedical communities and text mining results.
Developed and refined annotation tools and a metadata model in OWL, incorporating feedback from pharmaceutical and academic users.
Incorporated critiques and further requirements through discussions with colleagues.

Main Results:

Presents Annotation Ontology (AO), an open OWL-DL ontology for web-based scientific document annotation.
AO supports both human and algorithmic annotation, enabling "stand-off" metadata independent of the document.
Includes provenance and set models for versioning and annotation grouping; freely available under open-source license.

Conclusions:

Annotation Ontology (AO) fulfills critical requirements for an open, shareable OWL model for scientific document annotation metadata.
AO is poised to become a valuable common model for annotation metadata, facilitating wider use of biomedical ontologies in literature analysis.
Invites collaboration and welcomes new use cases for AO.
