Abstract: A system for analyzing a sentence emotion is provided. The system comprises a case repository, an input module, a sentence structure analyzing module, a similarity analyzing module and an emotion detection module. The case repository stores several case sentences and each case sentence comprises at least one major term and is corresponding to at least one emotion annotation. The input module receives an input sentence and the sentence structure analyzing module analyzes a sentence structure of the input sentence. The similarity analyzing module performs a semantic analysis and a syntax analysis according to the sentence structure to obtain a similarity level between the input sentence and each of the case sentences. The emotion detection module detects at least one emotion of the input sentence according to the similarity level between the input sentence and each of the case sentences.

Abstract: A method for instantly expanding a keyterm is provided. According to the query term, a data search process is performed by several search engines. Several document snippets related to the query term are obtained from the search engines. A related term table containing several keyterms corresponding to each snippet is built up by analyzing each of the document snippet. According to a position relationship between the each keyterm and the query term in each snippet, a correlation calculation is performed for giving each keyterm a correlation value. A semantic merging process is performed to merge the correlation values of the keyterms with the same semantic meaning to be a correlation indicator. Some of the keyterms are determined to form a keyterm set of the query term.

Abstract: The invention discloses a POI recommendation apparatus comprising a database and a POI recommendation module. The database provides a plurality of predetermined POIs, each having popularity information corresponding to a time period. The POI recommendation module finds out a recommended POI corresponding to the time period from the predetermined POIs according to the popularity information, and transmits the recommended POI to an electronic device.
