Information processing terminal and method, and information management apparatus and method
First Claim
1. An information processing terminal permitted to be connected to an information management apparatus for managing metadata items on electronic documents and annotation information items corresponding to the metadata items, the annotation information items on the electronic documents being generated by users, comprising a processing circuitry coupled to a memory, the processing circuitry being configured to:
- analyze an electronic document to generate a metadata item including text information in the electronic document and structure information on the electronic document, the structure information being associated with logical structure or layout of a document in the electronic document;
transmit the metadata item to the information management apparatus, to cause the information management apparatus to estimate a similar metadata item similar to the metadata item;
acquire a certain annotation information item corresponding to the similar metadata item, the certain annotation information item being included in the annotation information items, wherein the similar metadata item is estimated based on a first similarity degree, a second similarity degree, and a third similarity degree, wherein the first, second, and third similarity degrees has a weighting factor,wherein the first similarity degree is obtained based on an edition distance between keyword sequences in the metadata item and a stored metadata item;
wherein the second similarity degree indicates a degree of similarity between tree structures, in which a hierarchy of logical elements in the structure information is expressed;
wherein the third similarity degree indicates a degree of similarity in information as a combination of the structure information and the text information; and
output the annotation information item in association with the electronic document, the annotation information item being output at least by a voice output device.

Abstract
According to one embodiment, an information processing terminal includes a generator, an acquisition unit, and an output unit. The generator analyzes an electronic document to generate a metadata item including text information in an electronic document and structure information on the electronic document. The acquisition unit transmits the metadata item to an information management apparatus, causes the information management apparatus to estimate a similar metadata item similar to the metadata item and acquires an annotation information item corresponding to the similar metadata item. The output unit outputs the annotation information item in association with the electronic document.
