A knowledge evaluation apparatus, method, and system are provided. The knowledge evaluation apparatus includes an extraction module configured to extract at least one of triple information which is previously set with respect to a document for each field accumulated in an Internet community site; a classification module configured to classify and digitize the triple information extracted from the document for each field by a topic and an item; and a measurement module configured to measure knowledge maturity of the Internet community site based on the knowledge classified and digitized by the classification module.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A knowledge evaluation apparatus, comprising: an extraction module configured to extract at least one of triple information which is previously set with respect to a document for each field accumulated in an Internet community site; a classification module configured to classify and digitize the triple information extracted from the document for each field by a topic and an item; and a measurement module configured to measure knowledge maturity of the Internet community site based on the knowledge classified and digitized by the classification module. 2. The knowledge evaluation apparatus of claim 1, wherein the extraction module classifies the document for each field based on the field which is previously set by a manager in the Internet community site, and extracts the triple information with respect to the document for each field. 3. The knowledge evaluation apparatus of claim 1, wherein the classification module classifies the triple information by each topic according to a first entity name which is previously set, and classifies and digitizes the triple information classified by each topic by an item which is previously set. 4. The knowledge evaluation apparatus of claim 1, wherein the measurement module confirms whether there is a knowledge gap among each topic and items in each topic in the classified knowledge, and informs a member in the Internet community site. 5. The knowledge evaluation apparatus of claim 1, wherein the measurement module confirms a knowledge difference among items in each topic in the classified knowledge, and informs a member in the Internet community site. 6. The knowledge evaluation apparatus of claim 5, wherein, when it is confirmed that the knowledge difference is an error by a feedback of the member, the measurement module or another component deletes a document corresponding to the knowledge difference. 7. The knowledge evaluation apparatus of claim 5, wherein, when it is confirmed that the knowledge difference is content needed to be subdivided, the classification module subdivides the triple information corresponding to the knowledge difference into a plurality of topics or items. 8. The knowledge evaluation apparatus of claim 5, wherein the measurement module receives solutions from a plurality of members confirming the knowledge difference, and solves the knowledge difference. 9. The knowledge evaluation apparatus of claim 1, wherein the extraction module extracts the triple information with respect to the document for each field in each period which is previously set or when updating the document for each field. 10. A knowledge evaluation method, comprising: extracting at least one of triple information which is previously set with respect to a document for each field accumulated in an Internet community site; classifying and digitizing the triple information extracted from the document for each field by a topic and an item; and measuring knowledge maturity of the Internet community site based on the knowledge classified and digitized in the classifying and digitizing of the triple information. 11. The knowledge evaluation method of claim 10, wherein the extracting of at least one of the triple information comprises: classifying the document for each field based on the field which is previously set by a manager in the Internet community site; and extracting the triple information with respect to the document for each field. 12. The knowledge evaluation method of claim 10, wherein the classifying and digitizing of the triple information comprises: classifying the triple information by each topic according to a first entity name which is previously set; and classifying and digitizing the triple information classified by each topic by an item which is previously set. 13. The knowledge evaluation method of claim 10, wherein the measuring of the knowledge maturity comprises: confirming whether there is a knowledge gap among each topic and items in each topic in the classified knowledge, and informing a member in the Internet community site. 14. The knowledge evaluation method of claim 10, wherein the measuring of the knowledge maturity comprises: confirming the knowledge difference among items in each topic in the classified knowledge, and informing a member in the Internet community site. 15. The knowledge evaluation method of claim 14, when it is confirmed that the knowledge difference is an error by a feedback of the member, further comprising: after the measuring of the knowledge maturity, deleting a document corresponding to the knowledge difference. 16. The knowledge evaluation method of claim 14, when it is confirmed that the knowledge difference is content needed to be subdivided, further comprising: after the measuring of the knowledge maturity, subdividing the triple information corresponding to the knowledge difference into a plurality of topics or items. 17. The knowledge evaluation method of claim 14, wherein the measuring of the knowledge maturity comprises: receiving solutions from a plurality of members confirming the knowledge difference, and solving the knowledge difference. 18. The knowledge evaluation method of claim 10, wherein the extracting of the triple information extracts the triple information with respect to the document for each field each field by a previously set period. 19. A knowledge evaluation system, comprising: a database configured to store a document for each field accumulated in an Internet community site; and a knowledge evaluation apparatus configured to extract at least one of triple information which is previously set with respect to the document for each field, classify and digitize the triple information by a topic and an item, and measure knowledge maturity of the Internet community site. 20. The knowledge evaluation system of claim 19, wherein the knowledge evaluation apparatus extracts the triple information with respect to the document for each field in a period which is previously set or when updating the document for each field.
