6. A glossary management system comprising: an image forming apparatus; and an information processing device that communicates with the image forming apparatus over a network, wherein the image forming apparatus includes a processing circuit that executes a job of copying or printing a document, a collection circuit that collects from the document, text segments to be added to a glossary as entry terms, and a transmission circuit that transmits the text segments collected by the collection circuit to the information processing device, the information processing device includes a storage circuit that has a storage area for the glossary, a reception circuit that receives the text segments transmitted from the information processing device, and a registration circuit that adds each of the text segments received by the reception circuit to the glossary, the collection circuit includes an acquisition circuit that acquires text data of the document, an analysis circuit that performs analysis of the text data acquired by the acquisition circuit to identify a language of the document and parts of speech of text segments in the text data and extracts one or more text segments from the document based on the analysis, and a term matching circuit that performs matching for each of the extracted text segments against a public dictionary containing entry terms registered therein, the analysis circuit determines whether or not each extracted text segment is a proper noun, if the analysis circuit determines that the extracted text segment is not a proper noun, the term matching circuit performs matching of the extracted text segment against the public dictionary, and the registration circuit adds the extracted text segment to the glossary if the extracted text segment does not match any entry term in the public dictionary, and if the analysis circuit determines that the extracted text segment is a proper noun, the registration circuit adds the extracted text segment to the glossary without the term matching circuit performing matching of the extracted text segment against the public dictionary.
10. The glossary management system according to claim 6 , wherein the acquisition circuit receives a user input designating an internal-external classification of the document, and determines that the document is an internal document and acquires text data of the document if the internal-external classification indicates that the document is classified as an internal document.
