When talking of positive and negative wires the electrical terminology refers to DC voltages. In DC voltages the positive conductor is coloured red and the negative conductor is coloured black.
When talking about AC conductors the terminology refers to "hot" conductors and neutral conductors. Lamp cord in particular only use two wires to power table lamps and floor lamps. To get the polarity correct when wiring these devices the cord has to be identified. You will find that the neutral side of the cord will have a colour identifier or a raised rib. This could be a white marker on darker cables. The raised rib is more prevalent on two wire cables these days that the paint identifier.
