摘要： A method and system for obtaining a knowledge point implicit relationship are provided; first, establishing a knowledge point explicit relationship map according to knowledge point explicit relationship strengths; second, computing according to said knowledge point explicit relationship map a simple path set of two knowledge points; then, computing the implicit relationship strength values corresponding to each simple path in said simple path set; further, comparing the relationship strength values of the simple paths and setting as the significant implicit relationship strength value the simple path relationship strength having the largest value also greater than a preset threshold value. The described solution effectively avoids the problems of only using the relationship strengths between knowledge points and the ratio of relationship strengths to obtain the implicit relationship of knowledge points, the manner of searching for an implicit relationship being insufficiently accurate, and not performing normalization processing on the relationship strengths.

摘要： Method and system for detecting a correction pattern in a QR code are disclosed. In the detection of a correction pattern, coordinates of the correction pattern is at first roughly estimated according to the detected coordinates of the detection patterns and different QR code versions, then a square region is specified around the coordinates of the correction pattern, in which a search is performed repeatedly. Finally, in conjunction with the characteristic of the correction pattern itself, i.e., having a line segment meeting a predetermined ratio, the correction pattern may be accurately located in the predetermined area, without the need of searching patterns meeting a 1:1:1 ratio line by line in the entire QR code image.

摘要： A keyword expansion method and system are provided. The method comprises searching with a predetermined initial keyword to obtain current keywords used as a basis of a next search, performing loop search through keyword iteration. If a keyword error between keywords obtained in the current search and those keywords obtained in a previous search is less than a predetermined threshold, using the keywords obtained in the current search as expanded keywords of the initial keyword. With this method, the problem of manually establishing a thesaurus in the prior art may be solved. A method and system of automatically annotating a classified corpus is also provided. The method comprises: determining one or more initial core keywords for each class; obtaining expanded keywords for each class through expanding the initial core keywords; searching with the expanded keywords corresponding to a class to select a classified corpus and annotating the classified corpus.

摘要： In the method and system for knowledge extraction of this invention, knowledge extraction is realized through acquiring an initial sentence group including one or more sentences, and then comparing the length of the initial sentence group with an expected length to determine the initial sentence group to be expanded according to the comparison result. Since the sentence groups are formed by consecutive sentences, it may be guaranteed that the sentence groups themselves have good coherence in logic, so that the final sentence groups obtained through expanding the initial sentence groups have good coherence in logic correspondingly. Thus, this invention may override the drawback of lacking logical coherence in extracted knowledge information in the prior art.
