Embodiment Construction

[0051] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0052] Such as figure 1 As shown in , a method for topic or query-oriented multi-document summarization based on cluster arrangement includes the following steps:

[0053] (1) Read in the document, use the topic or query information as a sentence, divide each document and topic or query information into sentences and words, calculate the sentence similarity, and construct a sentence relationship graph;

[0054] The theme described in this embodiment includes user attributes, user questions, user inquiries and other personalized descriptions related to specific users. These descriptions are directly provided by users, and can certainly be obtained from user behavior analysis; if the theme is too long, Topics can be broken down into multiple sentences, ideally between 1 and 5 sentences. Since the topic in this embodiment is relatively short, the topic is rega...

Abstract

To overcome the defect in prior art, the related method considers fully the relation between sentences and the relation between sentence and user query to generate the abstract both with main file information and topic explanation or query answer, and applies difference penalty algorithm to ensure the novelty of abstract. This invention can meet individual request.

Description

technical field [0001] The invention belongs to the technical field of language and word processing, and in particular relates to a multi-document summarization method based on manifold-ranking orientated to a topic or query. Background technique [0002] Multi-document summarization is a core issue in the field of natural language processing, and has been widely used in applications such as text / Web retrieval in recent years. For example, search engines such as Google and Baidu all provide news services, and form multiple news topics by collecting news information on the Internet. Brief and concise summary. However, subject or query-oriented multi-document summarization can be regarded as a special multi-document summarization task. The multi-document summarization generated by this task needs to reflect a certain topic or query (or user attribute) specified by the user, that is, That is, the generated summaries can explain or answer the user's focus or information needs....
