1. A computer implemented method for analysing natural language to determine a sentiment between two entities discussed in the natural language, comprising the following steps: receiving the natural language at a processing circuitry; analysing the natural language to determine a syntactic representation which shows syntactic constituents of the analysed natural language and to determine a sentiment score of each constituent; determining which constituents link the two entities; and calculating an overall sentiment score for the sentiment between the two entities by processing the sentiment score of each constituent of the constituents determined to link the two entities.
