Abstract: There is provided a method for searching an unstructured dataset with a query, comprising: receiving a query comprising a value for a first token of a triplet, and a value for a relation term defining a relationship between the first token and a second token of the triplet, wherein the second token is defined as a variable element set with an undefined value, creating a plurality of enhanced queries for the query, each one of the plurality of enhanced queries including variations of the relation term, providing the plurality of enhanced queries for search by a search engine on at least one dataset of unstructured text-based data, receiving a plurality of documents in response to the search, analyzing the plurality of documents for extracting at least one value for the variable element of the triplet, and providing the at least one value for the variable element.

Abstract: A method of identifying an element. The method comprises setting a training set comprising a plurality of data units, selecting a function group of building block functions adapted for processing said plurality of data units, combining members of said function group to create a stream of a plurality of combination functions each complied from at least two members of said function group, applying each member of said stream on each of said plurality of data units to create a set of results, analyzing said set of results to identify a correlation between at least one member of said stream and a target variable for an analysis of said plurality of data units, and outputting said at least one member or an indication thereof.
