Claim 0:
1. An apparatus for providing a search service based on important sentences, comprising:
memory in which at least one program and a previously trained word importance measurement model are recorded; and
a processor for executing the program,
wherein the program includes
a word importance measurement unit for measuring an importance of each of multiple words included in input text in the input text based on the word importance measurement model; and
a sentence importance measurement unit for measuring an importance of each of at least one sentence included in the text based on the measured importance of each of the multiple words,
wherein the sentence importance measurement unit performs extracting at least one piece of attribute information based on importance scores of the multiple words included in the sentence and calculating the sentence importance score by assigning weights to the extracted at least one piece of attribute information,
wherein extracting the at least one piece of attribute information includes at least one of
calculating an average of the importance scores of the multiple words;
calculating the first number of words having an importance score equal to or greater than a predetermined second threshold, among the multiple words; and
calculating the second number of words corresponding to content words based on parts of speech,
wherein calculating the sentence importance score includes:
assigning weights to each of at least one of the average, the first number and the second number: and
summing the results of assigning weights to each of at least one of the average, the first number and the second number.
