We want to implement an automaton in the cell. It is based on a few simple rules on how to parse a simple sentence like
We target only the parts of speech (POS) tags which in these above grammars are:
This way the grammar can be implemented as a finite state automaton (FSA) and not as a push-down automaton. A finite state automation is a 5-tupel A = (Q, Σ, δ, s0, F), where Q is a finite set of states, Σ is the finite set of input symbols (alphabet), δ is the transition function, δ: Q × Σ -> Q, s0 is the start state and F is the set of final/accepting states. Our AimThe sentence in our project is a string of different reagents which will be introduced to the cell one by one. As soon as a wrong input is detected the cell will light up red. A sentence is finished by a stop reagent and then the cell will light up green. |
The image represents an automaton that show how state transition occurs in a particular sentence parsing automaton  |
