Methods and apparatus for spell checking

A method for spell checking on a page when loading and presenting the page by a client of a user, which is applied to a server, characterized in that the method comprises:

• receiving character segments corresponding to characters contained in the page to be presented at the client, wherein the character segments are determined by dividing the page according to a preset character segment dividing rule by the client;
• determining whether the page is being displayed to the user for the first time;
• in response to determining that the page is being displayed to the user for the first time, performing the following operations:
• obtaining character locations of wrong words in each of the received character segments;
• performing word segmentation on the received character segments and obtaining words corresponding to the received character segments, performing the spell checking on the words corresponding to the received character segments according to a preset spell checking rule, determining wrong words in the received character segments and obtaining character locations of the wrong words in the received character segments;
• caching the obtained character locations of the wrong words in each of the received character segments;
• in response to determining that the page was previously displayed to the user, performing the following operations:
• obtaining character locations of wrong words in each of the received character segments from the character locations cached when the page was displayed to the user for the first time;
• and
• sending the character locations of the wrong words in each of the received character segments to the client such that the client presents, to the user, each of the received character segments and mark wrong words in each of the received character segments according to the character locations of the wrong words in each of the received character segments,
• wherein the preset character segment dividing rule includes at least one of the following operations:
• determining all characters contained in the page as one character segment;
• in presenting the page, determining characters contained in a line of the page as one character segment;
• dividing characters contained in the page into character segments according to a preset character length;
• and
• after a character segment corresponding to characters contained in the page is obtained according to a preset character length, determining whether the character at the end of this character segment constitutes a word together with several characters at the beginning of the next character segment, and adjusting the obtained character segment according to the checking result,
• wherein characters contained in the page are obtained from a text stream system, and the text stream system is a system consisting of mapping rules and data pools.

An apparatus for spell checking on a page when loading and presenting the page, which is applied to a client of a user, characterized in that the apparatus comprises:

• a character segment determining module for determining character segments corresponding to characters contained in the page according to a preset character segment dividing rule;
• a character location obtaining module for obtaining character locations of wrong words in each of the determined character segments;
• a character location caching module for caching the character locations of the wrong words in each of the determined character segments after the character location obtaining module obtains the character locations;
• and
• a wrong word marking module for presenting, to the user, each of the determined character segments and marking, according to the character locations of the wrong words in each of the determined character segments, the wrong words in each of the determined character segments,
• wherein the character location obtaining module comprises:
• a character segment determining submodule for determining whether the page is being displayed to the user for the first time in response to displaying the page by the client;
• a word obtaining submodule for performing word segmentation on each of the determined character segments and obtaining words corresponding to each of the determined character segments in response to determining that the page is being displayed to the user for the first time;
• a first character location obtaining submodule for performing the spell checking on the words corresponding to each of the determined character segments according to a preset spell checking rule, determining wrong words in each of the determined character segments, and obtaining character locations of the wrong words in each of the determined character segments;
• and
• a second character location obtaining submodule for obtaining character locations of the wrong words in the determined character segments from character locations cached when the page was displayed to the user for the first time in response to determining that the page was previously displayed to the user,
• wherein the preset character segment dividing rule includes at least one of the following operations:
• determining all characters contained in the page as one character segment;
• in presenting the page, determining characters contained in a line of the page as one character segment;
• dividing characters contained in the page into character segments according to a preset character length;
• and
• after a character segment corresponding to characters contained in the page is obtained according to a preset character length, determining whether the character at the end of this character segment constitutes a word together with several characters at the beginning of the next character segment, and adjusting the obtained character segment according to the checking result;
• and
• wherein characters contained in the page are obtained from a text stream system, and the text stream system is a system consisting of mapping rules and data pools.

An apparatus for spell checking on a page when loading and presenting the page by a client of a user, which is applied to a server, characterized in that the spell checking is performed on the server, and the apparatus comprises:

• a character segment receiving module for receiving character segments corresponding to characters contained in the page to be presented at the client, wherein the character segments are determined by dividing the page according to a preset character segment dividing rule by the client;
• a character location obtaining module for obtaining character locations of wrong words in each of the received character segments;
• a character location caching module for caching the character locations of the wrong words in each of the received character segments after the character location obtaining module obtains the character locations;
• and
• a character location sending module for sending the character locations of the wrong words in each of the received character segments to the client such that the client is able to present, to the user, each of the character segments and mark wrong words in each of the determined character segments according to the character locations of the wrong words in each of the received character segments,
• wherein the character location obtaining module comprises:
• a character segment determining submodule for determining whether the page is being displayed to the user for the first time;
