Relevance-based entity selection for ad hoc retrieval

Recent developments have shown that entity-based models that rely on information from the knowledge graph can improve document retrieval performance. However, given the non-transitive nature of relatedness between entities on the knowledge graph, the use of semantic relatedness measures can lead to topic drift. To address this issue, we propose a relevance-based model for entity selection based on pseudo-relevance feedback, which is then used to systematically expand the input query leading to improved retrieval performance. We perform our experiments on the widely used TREC Web corpora and empirically show that our proposed approach to entity selection significantly improves ad hoc document retrieval compared to strong baselines. More concretely, the contributions of this work are as follows: (1) We introduce a graphical probability model that captures dependencies between entities within the query and documents. (2) We propose an unsupervised entity selection method based on the graphical model for query entity expansion and then for ad hoc retrieval. (3) We thoroughly evaluate our method and compare it with the state-of-the-art keyword and entity based retrieval methods. We demonstrate that the proposed retrieval model shows improved performance over all the other baselines on ClueWeb09B and ClueWeb12B, two widely used Web corpora, on the [email protected], and [email protected] metrics. We also show that the proposed method is most effective on the difficult queries. In addition, We compare our proposed entity selection with a state-of-the-art entity selection technique within the context of ad hoc retrieval using a basic query expansion method and illustrate that it provides more effective retrieval for all expansion weights and different number of expansion entities.     

一个超图嵌入问题的多项式时间近似算法

把定义在一个圈上的超图的每个超边映射为这个圈的一条路,每条超边的顶点均在对应的映射中,要求使圈中的任一边经过的路的最大次数最小,称此问题为超图在圈中的最小嵌入问题.将此问题归结为最近串选取问题,从而证明该问题存在多项式时间近似算法.     

英汉语主语对语类的选择

除了名词与代词都可以作主语外,英汉两种语言在对主语语类选择上似乎有着明显的不同,然而,本文试图证明这种不同只是表面的,实际上英汉两种语言中,主语都只能选择[+N]性成分,而不能选择[+V]性成分。

Selecting an open innovation community as an alliance partner: Looking for healthy communities and ecosystems

Organizations build strategic alliances with other firms with the intent of tapping into partners’ resources and capturing long-term value from these relationships. Such partnerships are typically governed by contractual or equity arrangements with clear mutual obligations. More recently, however, organizations have begun to seek strategic partnerships with open innovation communities, which are novel digitally enabled forms of organizing, and where contractual commitments are not possible. Thus, selecting the right open innovation community as an alliance partner becomes a more complex decision. We follow how the organizational decision makers, in two technology firms that were pioneers of forming strategic alliances with open innovation communities, developed metrics around making such decisions. We build upon Shah and Swaminathan’s (2008) contingency model of alliance partner selection and consider how it applies to the case of partnering with open innovation communities. This framework was useful in to frame our findings, yet our work recognizes and builds upon two key differences: 1) the evaluation metrics used in selecting an open innovation community were more focused on value creation than value capture; and 2) open ecosystem considerations, and not just partner-specific metrics, featured prominently in this type of alliance partner evaluation. We develop the notions of community and ecosystem health to refer to these new metrics.     

颠覆性技术遴选的指标体系与流程设计——基于扎根理论的多案例研究

针对目前颠覆性技术评价标准和评审流程系统性研究不足,基于国内外颠覆性技术遴选研究,选取我国科技部主办的全国颠覆性技术创新大赛为主案例,辅以其他颠覆性创新相关赛事、新型人才评价、新型职称评定机制及诺贝尔奖评审机制等6个案例交叉验证,运用程序化扎根理论分析得到111个概念、25个子范畴和8个主范畴,据此设计先质后量的评审原则,设置前期准备、初评、再评和现场评议的遴选流程.其中,在质的判断方面,运用德尔菲调查法,依靠专家直觉对项目是否具有颠覆性进行初步判断;在量的判断方面,邀请专家从技术颠覆、产业变革、经济价值、社会影响这4个维度进行打分,通过加权评分最终计算出各项目综合评分,层层递进以完成颠覆性技术的遴选.为增强颠覆性技术遴选方法的系统性以及各级政府和相关部门决策提供参考.
