Embodiment approach

[0070] Such as image 3 As shown, the information extracting device 300 includes: a first evaluation information initial seed obtaining device 310, configured to obtain an initial seed of the first evaluation information. According to an embodiment of the present invention, the first evaluation information initial seed obtaining means 310 may automatically obtain the first evaluation information initial seed. In the present invention, after word segmentation is performed on sentences, sentences containing parts of speech less than a certain threshold can be defined as short sentences, for example, the threshold can be limited to 5. Because the comment information sentence pattern of the short sentence is relatively simple, the initial seed of the first evaluation information to be extracted can be effectively obtained. In this step, if the first evaluation information is the evaluation object, for example, at least one noun / noun phrase contained in the short sentence can be u...

Abstract

The invention discloses an information extraction method and an information extraction device. The information extraction method comprises the following steps of: a) acquiring an initial seed of first evaluation information; b) determining second evaluation information associated with the seed of the first evaluation information; c) determining a new seed of the second evaluation information according to the weight of the second evaluation information which is generated by associating with the seed of the first evaluation information; d) determining the first evaluation information associatedwith the seed of the second evaluation information; e) determining a new seed of the first evaluation information according to the weight of the first evaluation information which is generated by associating with the seed of the second evaluation information; and f) judging whether the iteration termination condition is met or not, if so, outputting the acquired first evaluation information and the acquired second evaluation information, otherwise, executing the steps b to e again. In addition, the invention discloses the corresponding information extraction device.

Description

technical field [0001] The present invention generally relates to the field of network information processing, and in particular relates to an information processing technology for simultaneously extracting interrelated first evaluation information and second evaluation information from comment information. In particular, the present invention relates to an information extraction method and device. Background technique [0002] With the rapid development of the Internet, the amount of information on the Internet is increasing at an alarming rate every day. More and more people like to express their opinions on people, things and things on the Internet, and a large amount of information containing personal opinions and comments appears on the Internet. How to analyze and monitor comment information on the Internet, and how to reduce people's workload of reading a large number of relevant comment information, has become a research hotspot in the field of information processin...
