CitationAS: A Tool of Automatic Survey Generation Based on Citation Content

Abstract

Purpose

This study aims to build an automatic survey generation tool, named CitationAS, based on citation content as represented by the set of citing sentences in the original articles.

Design/methodology/approach

Firstly, we apply LDA to analyse topic distribution of citation content. Secondly, in CitationAS, we use bisecting K-means, Lingo and STC to cluster retrieved citation content. Then Word2Vec, WordNet and combination of them are applied to generate cluster labels. Next, we employ TF-IDF, MMR, as well as considering sentence location information, to extract important sentences, which are used to generate surveys. Finally, we adopt manual evaluation for the generated surveys.

Findings

In experiments, we choose 20 high-frequency phrases as search terms. Results show that Lingo-Word2Vec, STC-WordNet and bisecting K-means-Word2Vec have better clustering effects. In 5 points evaluation system, survey quality scores obtained by designing methods are close to 3, indicating surveys are within acceptable limits. When considering sentence location information, survey quality will be improved. Combination of Lingo, Word2Vec, TF-IDF or MMR can acquire higher survey quality.

Research limitations

The manual evaluation method may have a certain subjectivity. We use a simple linear function to combine Word2Vec and WordNet that may not bring out their strengths. The generated surveys may not contain some newly created knowledge of some articles which may concentrate on sentences with no citing.

Practical implications

CitationAS tool can automatically generate a comprehensive, detailed and accurate survey according to user’s search terms. It can also help researchers learn about research status in a certain field.

Originality/value

CitaitonAS tool is of practicability. It merges cluster labels from semantic level to improve clustering results. The tool also considers sentence location information when calculating sentence score by TF-IDF and MMR.

Vanishing Set-Aside Authority in International Commercial Arbitration

Summary

Traditional set-aside theory is subject to considerable challenges as a result of an uncompromising trend towards autonomy and internationalism in international arbitration. The silence and ambiguity of international law regarding enforcement of set-aside arbitral awards allow some states to abandon their own set-aside authority or ignore set-aside decisions made by competent courts. This article presents a range of evidence that demonstrates the enforcement of set-aside arbitral awards has become a common phenomenon. This article first introduces robust academic debates regarding set-aside authority. Then this article exposes omission and ambiguity in the legal source, which leads to confusion in enforcement proceedings of set-aside arbitral awards. This article describes and analyses selected cases and practical data in order to summarize the approaches taken by national courts when reviewing foreign set-aside decisions. Finally, this article briefly evaluates the most promising solutions to the contradictory enforcement proceedings of set-aside arbitral awards.
