| Claim | A method for text selection for use in a terminal having a touch screen, comprising: determining, in text for selection, a first display position of a start selection point and a first display position of an end selection point, wherein text between the start selection point and the end selection point is target text including at least one character; partitioning the text for selection into a plurality of text blocks based on semantic meaning; receiving a dragging operation on the touch screen corresponding to the start selection point or the end selection point; changing, according to the dragging operation, the first display position of the start selection point or the first display position of the end selection point to a corresponding second display position in unit of a text block; and adjusting, when at least one of the first display position of the start selection point and the first display position of the end selection point is located within a text block, the first display position of the start selection point and the first display position of the end selection point according to the text block, such that each of the first display position of the start selection point and the first display position of the end selection point is located at a nearest delimiter position, wherein the delimiter position is a position between two text blocks. The method of claim 1 , wherein partitioning the text for selection into a plurality of text blocks based on the semantic meaning comprises: determining a semantic granularity to be one of a word, a sentence, or a paragraph; and partitioning the text for selection into the plurality of text blocks conforming to the semantic granularity based on the semantic meaning. The method of claim 2 , wherein changing, according to the dragging operation, the first display position of the start selection point or the first display position of the end selection point to the corresponding second display position comprises one or more the following: moving forward the first display position of the start selection point by a first number of text blocks to obtain the corresponding second display position, when the dragging operation is to drag forward the start selection point; moving backward the first display position of the start selection point by a second number of text blocks to obtain the corresponding second display position, when the dragging operation is to drag backward the start selection point; moving forward the first display position of the end selection point by a third number of text blocks to obtain the corresponding second display position, when the dragging operation is to drag forward the end selection point; and moving backward the first display position of the end selection point by a fourth number of text blocks to obtain the corresponding second display position, when the dragging operation is to drag backward the end selection point; wherein the dragging forward is at least one of dragging leftward horizontally and dragging upward vertically, and the dragging backward is at least one of dragging rightward horizontally and dragging downward vertically. The method of claim 2 , wherein changing, according to the dragging operation, the first display position of the start selection point or the first display position of the end selection point into the corresponding second display position comprises: obtaining an ending position of the dragging operation; search for a delimiter position nearest to the ending position, wherein the delimiter position is a position between two text blocks; and determining the delimiter position as the corresponding second display position of the start selection point or the second display position of the end selection point. The method of claim 1 , wherein changing, according to the dragging operation, the first display position of the start selection point or the first display position of the end selection point to the corresponding second display position comprises performing at least one of: moving forward the first display position of the start selection point by a first number of text blocks to obtain the corresponding second display position, when the dragging operation is dragging forward the start selection point; moving backward the first display position of the start selection point by a second number of text blocks to obtain the corresponding second display position, when the dragging operation is dragging backward the start selection point; moving forward the first display position of the end selection point by a third number of text blocks to obtain the corresponding second display position, when the dragging operation is dragging forward the end selection point; and moving backward the first display position of the end selection point by a fourth number of text blocks to obtain the corresponding second display position, when the dragging operation is dragging backward the end selection point; wherein the dragging forward is at least one of dragging leftward horizontally and dragging upward vertically, and the dragging backward is at least one of dragging rightward horizontally and dragging downward vertically. The method of claim 1 , wherein changing, according to the dragging operation, the first display position of the start selection point or the first display position of the end selection point into the corresponding second display position comprises: obtaining an ending position of the dragging operation; searching for a delimiter position nearest to the ending position, wherein the delimiter position is a position between two text blocks; and determining the delimiter position as the corresponding second display position of the start selection point or the second display position of the end selection point. An apparatus for text selection, comprising: a touch screen; a processor; and a memory for storing instructions executable by the processor; wherein the processor is configured to: determine, in text for selection, a first display position of a start selection point and a first display position of an end selection point, wherein text between the start selection point and the end selection point is target text including at least one character; partition the text for selection into a plurality of text blocks based on semantic meaning; receive a dragging operation on the touch screen corresponding to the start selection point or the end selection point; change, according to the dragging operation, the first display position of the start selection point or the first display position of the end selection point to a corresponding second display position in unit of a text block; and adjust, when at least one of the first display position of the start selection point and the first display position of the end selection point is located within a text block, the first display position of the start selection point and the first display position of the end selection point according to the text block, such that each of the first display position of the start selection point and the first display position of the end selection point is located at a nearest delimiter position, wherein the nearest delimiter position is a position between two text blocks.
