Method and Apparatus of Knowledge Base Building

摘要

The present disclosure provides a method and apparatus of knowledge base building to automatically construct a knowledge base. Furthermore, the disclosed techniques can be used to improve the accuracy of that knowledge base. In one aspect, a method acquires a sentence from a webpage using a basic data processing layer of a computing apparatus. The acquired sentence is parsed into words using a data mining layer of the computing apparatus. One or more representative words in a first category of a knowledge base are matched with the words parsed from the acquired sentence. When there is a match between one of the representative words and one of the words parsed from the acquired sentence, a string of words adjacent the matched word in the acquired sentence is added to the first category as a first entry. When matching the words parsed from the acquired sentence with a second entry of a second category of the knowledge base, it is determined whether or not an established correlation exists between the first category and the second category. When it is determined that an established correlation exists between the first category and the second category, a correlation between the first entry of the first category and the second entry of the second category is established. The present disclosure also discloses methods for searching information and computing apparatuses that implement the methods.
