A system, method, and computer program product are configured to extract key value pair (KVP) data from one or more documents; obtain a content index for the one or more documents; and enhance the content index with the KVP data to provide a KVP content index.

Document content search index

One embodiment of the invention provides a method for creating an inverted index. The method comprises receiving documents to be indexed, classifying the documents to determine document types of the documents, and analyzing the documents to identify crucial portions of the documents. The method further comprises generating, based on the analyzing, inverted indexes corresponding to indexing words contained in the documents. Each inverted index corresponding to each indexing word includes a document type tier identifying at least one document type of at least one document containing the indexing word, and the inverted index further includes a crucial list identifying each document which contains the indexing word in a crucial portion of the document if the indexing word occurs in the crucial portions of the documents. The method further comprises selectively caching each inverted index based on whether the inverted index includes a crucial list.

Method and system for creating an index

In an approach, a processor identifies a plurality of text separators in a borderless table, a text separator of the plurality of text separators defining a non-text region between two consecutive text lines in the borderless table. A processor classifies the plurality of text separators into a number of target clusters comprised in a target group based on property information related to the plurality of text separators, the number of target clusters corresponding to a number of separator types. A processor provides indication information to indicate respective separator types of the plurality of text separators based on a result of the classifying.

Line item detection in borderless tabular structured data

A method, computer system, and a computer program product is provided for generating a detailed thumbnail and/or preview of a content. In one embodiment the technique comprises analyzing data obtained from a content and classifying it according to a plurality of specific types. A plurality of key information may be then extracted from the data according to the classification. A plurality of key-values are correlated to the plurality of key information so as to provide a plurality of key-value pairs. These pairs are consolidated accordingly to generate a thumbnail and/or a preview that at least renders the key information provided by the consolidated key-value pairs as a rendering.
