档案馆现行文件收集工作研究——兼论与档案收集工作的差异

档案馆的档案收集工作是档案工作的基础性工作,现行文件的收集工作则是档案馆开展现行文件利用服务工作的先提条件,本文对比分析了两项工作在目的、依据、内容、范围、期限等方面存在的差异,指出档案馆既要继续做好档案的收集工作,又要立足于政务信息公开的需要做好现行文件的收集工作。     

从概念角度论述保持电子文件真实性的要求

电子文件真实性问题的研究成为电子文件管理的重中之重,有必要确定评估和维护永久保存的电子文件的真实性的要求。然而在讨论这些要求之前,有必要解释确定要求的概念基础。在本文中,将概念要求分为两个部分,第一部分要求包括支持电子文件真实性假设的要求;第二部分要求包括支持电子文件真实性拷贝的要求。

Bakhtin Applied: Employing Dialogism to Analyze the Interplay of the Ideologies of Individualism and Community Within the Discourse of Alcoholics Anonymous

An ongoing debate regarding the nature of therapeutic communities concerns the extent to which these communities reinforce the ideologies of individualism and community. This article engages this discussion through a process of social text analysis informed by the dialogism theory of Russian philosopher and literary scholar Mikhail Bakhtin. Dialogism seeks to understand the multiple voices interpenetrating particular utterances, revealing an emergent social construction of meaning. Applying this approach to examples of discourse from a prominent therapeutic community, Alcoholics Anonymous, illustrates how meaning in the discourse of this movement can be understood to emerge among the interplay between the ideologies of individualism and community as expressed within the movement's narrative practice.     

Construction of query concepts based on feature clustering of documents

In Information Retrieval, since it is hard to identify users’ information needs, many approaches have been tried to solve this problem by expanding initial queries and reweighting the terms in the expanded queries using users’ relevance judgments. Although relevance feedback is most effective when relevance information about retrieved documents is provided by users, it is not always available. Another solution is to use correlated terms for query expansion. The main problem with this approach is how to construct the term-term correlations that can be used effectively to improve retrieval performance. In this study, we try to construct query concepts that denote users’ information needs from a document space, rather than to reformulate initial queries using the term correlations and/or users’ relevance feedback. To form query concepts, we extract features from each document, and then cluster the features into primitive concepts that are then used to form query concepts. Experiments are performed on the Associated Press (AP) dataset taken from the TREC collection. The experimental evaluation shows that our proposed framework called QCM (Query Concept Method) outperforms baseline probabilistic retrieval model on TREC retrieval.
