Method for summarization of threads in electronic mail

The present invention discloses a pre-processing summarization technique that makes use of knowledge specific to the electronic mail domain to pre-process an electronic mail message so that commercially-available document summarization software can subsequently generate a more useful summary from the message. The summarization technique removes extraneous headers, quoted text, forward information, and electronic signatures, leaving more useful text to be summarized. If an enclosing electronic mail thread exists, the summarization technique uses the electronic mail message's ancestors to provide additional context for summarizing the electronic mail message. The disclosed system can be used with IBM Lotus Notes and Domino infrastructure, along with existing single-document summarizer software, to generate a summary of the discourse activity in an electronic mail thread dynamically. The summary may be further augmented to list any names, dates, and names of companies that are present in the electronic mail message being summarized.

Document summarization based on topicality and specificity

Topicality scores are determined for a number of phrasal expressions in documents. Phrasal expressions may be noun phrases, with or without corresponding prepositional phrases, subject-verb pairs, and verb-object pairs. The documents describe some topic or multiple topics. Techniques can be used to determined how the phrasal expression compares with the topic or topics being described in the documents. Specificities are determined for the phrasal expressions. Techniques may be used to determine whether phrasal expressions are more or less specific than other phrasal expressions. An order is determined for the phrasal expressions by using the topicality scores and the specificities. The order may be represented as a phrasal expression tree, for example. The phrasal expression tree may be displayed to a user, and the user can navigate through the phrasal expression tree, and therefore through the one or more documents.

An Evolutionary Summary Generation Method for Internet News Events

The invention relates to an evolutionary summarization generation method for internet news events. The evolutionary summarization generation method includes the steps: inputting a related news document set; representing documents as topic facture vectors by an LDA (latent Dirichlet allocation) topic model; clustering the documents represented as the topic facture vectors; calculating local scoresof the documents in each topic; calculating global scores of the documents in each topic; calculating final scores of the documents in each topic; extracting document titles with high scores from eachtopic to serve as a summary according to time sequence; outputting the summary. The dimensions of the topic facture vectors are first preset values, and each cluster represents one topic. According to the evolutionary summarization generation method for the internet news events, the extracted summary has dynamic evolvability and is coherent and strong in readability, and experimental results indicate that the system is greatly improved in terms of redundancy, coherence and dynamic evolvability as compared with a traditional multi-document summarization system.

Provided is an automatic document summarization extraction method based on term vectors. The method includes the steps that S1, a deep neural network model is used for training linguistic data to obtain term vector representation of feature terms; S2, a sentence graph model is constructed; S3, the weights of sentences are calculated; S4, a maximum marginal relevance algorithm is used for generating a summarization. According to the method, a linguistic data set is collected and preprocessed to obtain a training feature linguistic data set, the deep neural network model is used for training the constructed training feature linguistic data set to obtain the term vectors of the feature terms, a candidate document set and a candidate sentence set are obtained from the linguistic data set through preset search terms, the semantic similarity between the senesces is obtained according to the term vectors of the feature terms, and then the semantic relation between every two sentences is obtained. The problem that in a traditional calculation method based on term co-occurrence, calculation errors are caused under the condition that semantic meaning is identical but terms are different is avoided, and therefore the accuracy of similarity calculation and the performance of the summarization are improved.
