Sentiment search is a new feature in Lexxe Search Engine. It calculates the sentiment score of the keyword in the context using syntactic and semantic methods. Each webpage will be given a sentiment score of that keyword. An aggregated sentiment score will also be delivered from all the scores in individual pages.
Search Sentiment Options
There are some "sentiment search" options under the search query slot:
1) "No Sentiment" means no sentiment is calculated, just like an ordinary search engine.
2) "All Sentiment" means all sentiments, i.e. positive, negative and neutral. The ranking of the results will be based on keyword relevance to each text.
3) "Positive" means all results are positive and they are ranked from most positive to least positive.
4) "Negative" means all results are negative and they are ranked from most negative to least negative.
5) "Neutral" means all the results are neutral.
6) "Comparison" means you can enter up to four items of keywords, each separated by a comma:
e.g. Intel, Apple, Motorola, Cisco
This option is for Web and News search only.
Category Options
There are 13 individual categories in News and Sindex. And there is an "All" option in Category putting all categories together. A sentiment score is associated with each category showing the sentiment scores of all the articles in that category.
Categories offer a way to narrow down information into specific domains.
