a pictorial-symbol opinion-score retriever configured to retrieve within the pictorial-symbol dictionary memory, at least one of the opinion scores which corresponds to the at least one extracted pictorial-symbol; and
an opinion-score calculator configured to calculate an aggregate net opinion score for the message, based on an aggregate opinion score for the at least one extracted pictorial-symbol, wherein the aggregate opinion score is calculated with the at least one retrieved opinion score for the at least one extracted pictorial-symbol,wherein the pictorial-symbol dictionary memory stores an additional correspondence between at least one selected pictorial-symbol and at, least one intensity rate when the at least one selected pictorial-symbol is used as a linguistic modifier for describing another pictorial symbol on which the at least one selected pictorial-symbol depends linguistically, andthe pictorial-symbol extractor extracts from the message, as a modificative pictorial-symbol, at least one of the used pictorial-symbols in the message which is coincident with at least one of the at least one selected pictorial-symbol stored in the pictorial-symbol dictionary memory,the server further comprising;
an intensity-rate retriever configured to retrieve within the pictorial-symbol dictionary memory, at least one of the at least one intensity rate which corresponds to the at least one extracted modificative-pictorial-symbol; and
