چکیده

It is necessary to find a proper arrangement of sentences in order to generate a well-organized summary from multiple documents. In this paper we describe an approach to coherent sentence ordering for summarizing newspaper articles. Since there is no guarantee that chronological ordering of extracted sentences, which is widely used by conventional summarization system, arranges each sentence behind presupposed information of the sentence, we improve chronological ordering by resolving antecedent sentences of arranged sentences. Combining the refinement algorithm with topical segmentation and chronological ordering, we address our experiment to test the effectiveness of the proposed method. The results reveal that the proposed method improves chronological sentence ordering.

Context processing plays an important role in different Natural Language Processing applications. Sentence ordering is one of critical tasks in text generation. Following the same order of sentences in the row sources of text is not necessarily to be applied for the resulted text. Accordingly, a need for chronological sentence ordering is of high importance in this regard. Some researches follo...

Domain-Independent Shallow Sentence Ordering

We present a shallow approach to the sentence ordering problem. The employed features are based on discourse entities, shallow syntactic analysis, and temporal precedence relations retrieved from VerbOcean. We show that these relatively simple features perform well in a machine learning algorithm on datasets containing sequences of events, and that the resulting models achieve optimal performan...

A preference learning approach to sentence ordering for multi-document summarization

Ordering information is a difficult but an important task for applications generating naturallanguage texts such as multi-document summarization, question answering, and conceptto-text generation. In multi-document summarization, information is selected from a set of source documents. Therefore, the optimal ordering of those selected pieces of information to create a coherent summary is not obv...
