Abstract

The invention provides a method and a system for automatically classifying objects. The method comprises the following steps: inputting a group of the objects and a class hierarchy for classifying theobjects; acquiring body information correlative with a field; using a method based on the body information to classify each object into the class hierarchy so as to obtain a first classification result; using a method based on information retrieval (IR) to classify each object into the class hierarchy so as to obtain a second classification result; and combining the first and the second classification results to obtain a final classification result. The method and the system can be applied to single-layer or multi-layer class hierarchies, and can effectively and accurately achieve object classification so as to obtain a smaller classification result granularity.

Description

technical field [0001] The present invention generally relates to information retrieval and text data mining, and more particularly, the present invention relates to methods and systems for automatically classifying objects (eg, documents, mail, etc.). Background technique [0002] As the amount of information available online, such as electronic documents, continues to grow, it becomes increasingly difficult for people to understand and effectively utilize this vast amount of information. Therefore, helping people organize information and find interesting information in an effective and efficient manner has become a very challenging task. [0003] Information Retrieval (IR) is the science of searching for information in collections of objects (such as documents). Depending on the object of processing, it can further be divided into searches for pieces of information contained in documents, searches for documents themselves, searches for metadata describing documents, or se...
