Abstract: The invention provides a system to categorize user queries including an identification component that receives an original user query and identifies a what-component and a where-component using the original user query, a first classification component that analyzes and classifies the what-component of the original user query, a second classification component that analyzes and processes the where-component of the original user query, and a transmission component that sends the results of the first and second classification components and a processed user query to a backend search engine.

Abstract: The invention provides for a system for ranking data including a first calculation component that calculates a qualitative semantic similarity score of at least one data entry from at least one data source, a second calculation component that calculates a general quantitative score of the at least one data entry from at least one data source, a third calculation component that combines the qualitative semantic similarity score and the general quantitative score of the at least one data entry from at least one data source into a vector score for the at least one data entry, and a ranking component that ranks the at least one data entry among other data entries using the vector score. General qualitative scores such as distance scores are never overruled by semantic scores.

Abstract: The invention provides for a system to transform user queries including a reception component that receives an original user query, a transformation component to transform the original user query into a processed user query, and a transmission component that sends the processed user query to a backend search engine.

Abstract: The invention provides for a system to correlate data including a feed data set, a correlated data set, and a correlator that links entries in the feed data set with entries in the correlated data set.

Abstract: The invention provides a system for searching data including an online query processing system, a ranking system, an offline data processing component, and a backend search engine.

Abstract: The invention provides for a system to select data including a reception component that receives at least one data entry from at least one data source, a processor component to determine the entropy of a word extracted from the at least one data entry, a filtering component to select reliable words, wherein reliable words are words with low entropy values, the filtering component further excluding words with high entropy values, and a transmission component to output a set of reliable words, wherein the set of reliable words is associated with the at least one data entry from which the reliable words were extracted.
