A method for transaction analysis comprises extracting a plurality of character groups from a plurality of transaction identifiers, determining an inverse document frequency value for each of the plurality of character groups, generating, for a first transaction and a second transaction, respectively, a first transaction signature and a second transaction signature corresponding to the plurality of character groups, and computing a distance between the first and second transaction signatures.

A system, method and computer program product for conducting questions and answers with deferred type evaluation based on any corpus of data. The method includes processing a query including waiting until a 'Type' (i.e. a descriptor) is determined AND a candidate answer is provided. Then, a search is conducted to look (search) for evidence that the candidate answer has the required Lexical Answer Type (e.g., as determined by a matching function that can leverage a parser, a semantic interpreter and/or a simple pattern matcher). Prior to or during candidate answer evaluation, a process is provided for extracting and storing collections of entity-type pairs from semi-structured text documents. During QA processing and candidate answer scoring, a process is implemented to match the query LAT against the lexical type of each provided candidate answer and generate a score judging a degree of match.
