and a controller operably coupled with the display and configured to: cause the display to display a webpage including a plurality of text contents, each of the plurality of text contents being selectable to access a corresponding link; divide the plurality of text contents based on blank units to generate a plurality of tokens and a token table in which at least one link and a corresponding one of the plurality of tokens are associated; assign a number to a text content corresponding to a token having two or more links based on the generated token table, wherein no number is assigned to a text content corresponding to a token having less than two links; enter a voice recognition mode; and based on entering the voice recognition mode, search for duplicate words included in the plurality of text contents; and based on the search identifying that a specific noun is included in each text content of a subset of the plurality of text contents: cause the display to display sequential numbers at a side of each text content of the subset of the plurality of text contents; receive a voice command; based on determining that the voice command identifies one of the displayed sequential numbers, access the link corresponding to the text content corresponding to the identified one of the displayed sequential numbers, wherein the link corresponding to the text content corresponding to the identified one of the displayed sequential numbers is accessed without requiring earlier reception of another voice command that identifies the specific noun; and based on determining that the voice command identifies one of the plurality of text contents and not one of the displayed sequential numbers, access the link corresponding to the identified one of the plurality of text contents. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the controller is further configured to: compare text contents corresponding to the token having the two or more links with each other; and delete a correspondence relationship of the token and a link corresponding to the token from the token table, wherein the link corresponding to the token is same as one of the two or more links. ### Claim 3 (depends on 1) The display device according to claim 1, wherein the controller is further configured to: extract a paragraph tag indicating a paragraph when an anchor tag for opening another webpage is not extracted; determine whether a link exists from the extracted paragraph tag; and assign a number to a text content corresponding to the paragraph tag based on determining that the link exists. ### Claim 4 (depends on 3) The display device according to claim 3, wherein the controller is further configured to determine whether a state change of the text content corresponding to the paragraph tag occurs in response to an input focus event to the text content. ### Claim 5 (depends on 4) The display device according to claim 4, wherein the focus event corresponds to positioning a pointer on the text content corresponding to the paragraph tag, wherein the pointer is controlled according to movement of a remote control device. ### Claim 6 (depends on 5) The display device according to claim 5, wherein the controller is further configured to determine that a link exists in the text content when the state change occurs in response to the focus event. ### Claim 7 (depends on 6) The display device according to claim 6, wherein the state change includes a change in a displayed size of the text content or a display of another text content. ### Claim 8 (depends on 6) The display device according to claim 6, wherein the controller is further configured to cause the display to display other numbers other than the displayed sequential numbers when an image corresponding to the link exists in the webpage. ### Claim 9 (depends on 8) The display device according to claim 8, wherein the controller is further configured to, when a plurality of overlapping images corresponding to the link exist in the webpage, cause the display to display a number only on a non-hidden image of the plurality of overlapping images. ### Claim 10 (depends on 1) The display device according to claim 1, wherein the controller is further configured to assign a number to a direction key in the webpage which is associated with a link. ### Claim 11 (depends on 1) The display device according to claim 1, wherein each of the plurality of text contents respectively corresponds to the corresponding link extracted based on a source code of the webpage.
