METHOD AND SYSTEM FOR ASSESSING ENVIRONMENTAL IMPACTS CAPABLE OF ESTABLISHING WEIGHTING FACTORS FOR ENVIRONMENTAL IMPACT CATEGORIES USING INTERNET SEARCH STATISTICS

摘要

According to embodiments of the present invention, in order to be provided with the search frequency of each search word from an Internet search engine, an environmental impact assessment system may include: a search frequency inquiry unit for inquiring about the search frequency of each search word for each predetermined environmental impact category to the Internet search engine; a search frequency calculation unit for calculating relative search frequencies for each search word in a predetermined environmental impact category; an environmental impact category-based search search calculation unit for calculating search frequencies for each environmental impact category based on relative search frequency values for each search word with respect to search words in each environmental impact category; and a category-based environmental impact assessment unit for calculating a comprehensive environmental impact assessment value through weighted summation of the assessment values for each category which are calculated for each environmental impact category by using the weighted values for each environmental impact category.
