Abstract: A computer-implemented method for outputting a data element to a user for an operation by the user to give a label to plural data elements, includes: selecting the data element by either one of a first strategy and a second strategy, the first strategy being a strategy for selecting a data element which has been predicted with a low confidence level, the second strategy being a strategy for selecting a data element which has been predicted with a high confidence level; outputting the selected data element so as for a user to give a label to the selected data element; and switching between the first strategy and the second strategy depending on a progress degree of labeling by the user.

Abstract: A method and system are provided for performing a legal document search. The method includes finding, by a processor, for each of a plurality of documents, a respective law clause related thereto, to obtain a plurality of related law clauses. The method further includes constructing, by the processor, a graph having nodes defined by the plurality of documents and the plurality of related law clauses and having edges defined by (1) relations between the plurality of documents and the plurality of related law clauses and (2) relations between the plurality of documents. The method further includes identifying, by the processor, from the plurality of documents, one or more candidate documents that are similar to an input query document by mining the graph using similarity criteria.
