My Lecture Style
I may tend to talk fast, especially when excited
Class materials are highly interdisciplinary
Use your questions to slow me down
Ask for clarification, repetition of a strange phrase, jargons
“If in doubt, speak it out”

Forward Class Reviewing
This is for overview, not content
Don’t worry if you do not understand some of the words, that’s
why you want to take this class.
Gives an idea of what is coming
Order of presentation might be shuffled to accommodate
everyone’s schedule
Topics may be adjusted with progresses of the class

Week 11: Text Mining, Gene Ontology,
Data Management
Ontology seeks to describe or posit the basic categories
and relationships of being or existence to define entities
and types of entities within its framework. Ontology can
be said to study conceptions of reality (Wikipedia).
GO is a database of terms for genes
Terms are connected as a directed acyclic graph
Levels represent specifity of the terms (not normalized)
GO contains three different sub-ontologies:
Molecular function
Biological process
Cellular component
