Abstract: The present document relates to a system and method for searching a document using one or more search terms. In particular, the present document relates to a resource efficient method for searching a document within a database of documents. A method for determining an inverse index on an electronic device including a database is described. The inverse index is configured to map a plurality of text data entities from the database to a search term. The method includes determining a plurality of relevance vectors for a plurality of text data entities from the database. Determining a relevance vector for a text data entity from the database includes: selecting N terms which are descriptive of the text data entity; and determining the relevance vector from the selected N terms. Furthermore, the method includes determining the inverse index comprising a plurality of records.

Abstract: The application relates to a method for facilitating the selection of an information source, comprising: providing two search strings to an electronic device; obtaining strings and relationship values, wherein each relationship value defines a degree of semantic relationship between two strings or a string and a search string and wherein at least some of the strings match with elements in the information sources; and displaying at least some of the matching strings on a two-dimensional map. The map comprises a first, a second and a third region, the first region comprising matching strings that have a non-zero relationship value only with regard to the first search string, the second region comprising matching strings that have a non-zero relationship value only with regard to the second search string and the third region comprising matching strings that have non-zero relationship values with regard to the first and the second search string.

Abstract: A method for enabling machine learning from unstructured documents is described. The method comprises analyzing at an electronic device, one or more structured databases, thereby providing a mapping between a plurality of referenced character strings and a corresponding plurality of type labels; providing, at the electronic device, a first unstructured document comprising a plurality of unstructured character strings; analyzing the first unstructured document to identify a first character string of the plurality of unstructured character strings which is associated with a first referenced character string of the plurality of referenced character strings; associating, within the first unstructured document, a first type label which is mapped to the first referenced character string to the first character string; and determining a training set for machine learning from the first unstructured document comprising the association to the first type label.
