Claim Text:
1. A computer implemented method for analysing natural language contained in electronic text to determine a sentiment between two entities discussed in the natural language, comprising the following steps: receiving, via an input module, the electronic text containing the natural language at a processing circuitry; using an input/output subsystem of the processing circuitry to move the received natural language to a data storage; analysing the natural language in the data storage to determine a syntactic representation which shows syntactic constituents of the analysed natural language and to determine a sentiment score of each constituent, wherein each constituent is a sentiment (sub)context, and wherein determining a sentiment score of each constituent comprises: determining which constituents link the two entities; 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; and outputting, by a computer processor, the overall sentiment score for the sentiment between the two entities discussed by the natural language contained in the electronic text.
